+ * either in BL1 or BL31 depending on the platform and assists in identifying
+ * and notifying the features which are enabled but not supported by the PE.
+ *
+ * It reads all the enabled features ID-registers and ensures the features
+ * are supported by the PE.
+ * In case if they aren't it stops booting at an early phase and logs the error
+ * messages, notifying the platforms about the features that are not supported.
+ *
+ * Further the procedure is implemented with a tri-state approach for each feature:
+ * ENABLE_FEAT_xxx = 0 : The feature is disabled statically at compile time
+ * ENABLE_FEAT_xxx = 1 : The feature is enabled and must be present in hardware.
+ *                       There will be panic if feature is not present at cold boot.
+ * ENABLE_FEAT_xxx = 2 : The feature is enabled but dynamically enabled at runtime
+ *                       depending on hardware capability.
+ *
+ * For better readability, state values are defined with macros namely:
+ * { FEAT_STATE_0, FEAT_STATE_1, FEAT_STATE_2 } taking values as their naming.

+Feature Overview
+================
+
+This page provides an overview of the current |TF-A| feature set. For a full
+description of these features and their implementation details, please see
+the documents that are part of the *Components* and *System Design* chapters.
+
+The :ref:`Change Log & Release Notes` provides details of changes made since the
+last release.
+
+Current features
+----------------
+
+-  Initialization of the secure world, for example exception vectors, control
+   registers and interrupts for the platform.
+
+-  Library support for CPU specific reset and power down sequences. This
+   includes support for errata workarounds and the latest Arm DynamIQ CPUs.
+
+-  Drivers to enable standard initialization of Arm System IP, for example
+   Generic Interrupt Controller (GIC), Cache Coherent Interconnect (CCI),
+   Cache Coherent Network (CCN), Network Interconnect (NIC) and TrustZone
+   Controller (TZC).
+
+-  A generic |SCMI| driver to interface with conforming power controllers, for
+   example the Arm System Control Processor (SCP).
+
+-  SMC (Secure Monitor Call) handling, conforming to the `SMC Calling
+   Convention`_ using an EL3 runtime services framework.
+
+-  |PSCI| library support for CPU, cluster and system power management
+   use-cases.
+   This library is pre-integrated with the AArch64 EL3 Runtime Software, and
+   is also suitable for integration with other AArch32 EL3 Runtime Software,
+   for example an AArch32 Secure OS.
+
+-  A minimal AArch32 Secure Payload (*SP_MIN*) to demonstrate |PSCI| library
+   integration with AArch32 EL3 Runtime Software.
+
+-  Secure Monitor library code such as world switching, EL1 context management
+   and interrupt routing.
+   When a Secure-EL1 Payload (SP) is present, for example a Secure OS, the
+   AArch64 EL3 Runtime Software must be integrated with a Secure Payload
+   Dispatcher (SPD) component to customize the interaction with the SP.
+
+-  A Test SP and SPD to demonstrate AArch64 Secure Monitor functionality and SP
+   interaction with PSCI.
+
+-  SPDs for the `OP-TEE Secure OS`_, `NVIDIA Trusted Little Kernel`_,
+   `Trusty Secure OS`_ and `ProvenCore Secure OS`_.
+
+-  A Trusted Board Boot implementation, conforming to all mandatory TBBR
+   requirements. This includes image authentication, Firmware Update (or
+   recovery mode), and packaging of the various firmware images into a
+   Firmware Image Package (FIP).
+
+-  Pre-integration of TBB with the Arm CryptoCell product, to take advantage of
+   its hardware Root of Trust and crypto acceleration services.
+
+-  Reliability, Availability, and Serviceability (RAS) functionality, including
+
+   -  A Secure Partition Manager (SPM) to manage Secure Partitions in
+      Secure-EL0, which can be used to implement simple management and
+      security services.
+
+   -  An |SDEI| dispatcher to route interrupt-based |SDEI| events.
+
+   -  An Exception Handling Framework (EHF) that allows dispatching of EL3
+      interrupts to their registered handlers, to facilitate firmware-first
+      error handling.
+
+-  A dynamic configuration framework that enables each of the firmware images
+   to be configured at runtime if required by the platform. It also enables
+   loading of a hardware configuration (for example, a kernel device tree)
+   as part of the FIP, to be passed through the firmware stages.
+   This feature is now incorporated inside the firmware configuration framework
+   (fconf).
+
+-  Support for alternative boot flows, for example to support platforms where
+   the EL3 Runtime Software is loaded using other firmware or a separate
+   secure system processor, or where a non-TF-A ROM expects BL2 to be loaded
+   at EL3.
+
+-  Support for the GCC, LLVM and Arm Compiler 6 toolchains.
+
+-  Support for combining several libraries into a "romlib" image that may be
+   shared across images to reduce memory footprint. The romlib image is stored
+   in ROM but is accessed through a jump-table that may be stored
+   in read-write memory, allowing for the library code to be patched.
+
+-  Support for the Secure Partition Manager Dispatcher (SPMD) component as a
+   new standard service.
+
+-  Support for ARMv8.3 pointer authentication in the normal and secure worlds.
+   The use of pointer authentication in the normal world is enabled whenever
+   architectural support is available, without the need for additional build
+   flags.
+
+-  Position-Independent Executable (PIE) support. Currently for BL2, BL31, and
+   TSP, with further support to be added in a future release.
+
+Still to come
+-------------
+
+-  Support for additional platforms.
+
+-  Refinements to Position Independent Executable (PIE) support.
+
+-  Continued support for the FF-A v1.0 (formally known as SPCI) specification, to enable the
+   use of secure partition management in the secure world.
+
+-  Documentation enhancements.
+
+-  Ongoing support for new architectural features, CPUs and System IP.
+
+-  Ongoing support for new Arm system architecture specifications.
+
+-  Ongoing security hardening, optimization and quality improvements.

+Release Processes
+=================
+
+Project Release Cadence
+-----------------------
+
+The project currently aims to do a release once every 6 months which will be
+tagged on the master branch. There will be a code freeze (stop merging
+non-essential changes) up to 4 weeks prior to the target release date. The release
+candidates will start appearing after this and only bug fixes or updates
+required for the release will be merged. The maintainers are free to use their
+judgement on what changes are essential for the release. A release branch may be
+created after code freeze if there are significant changes that need merging onto
+the integration branch during the merge window.
+
+The release testing will be performed on release candidates and depending on
+issues found, additional release candidates may be created to fix the issues.

+      boot. For the earlier architectures PMCR register is saved/restored on
+      secure world entry/exit from/to Non-secure state, and cycle counting gets
+      disabled by setting PMCR.DP bit.
+  - AArch64: Disable Secure Cycle Counter
+    - For ARMv8.5 the counter gets disabled by setting `MDCR_El3.SCCD` bit on
+      CPU cold/warm boot. For the earlier architectures PMCR_EL0 register is
+      saved/restored on secure world entry/exit from/to Non-secure state, and

+  - dtb: DTB creation not supported when building on a Windows host.
+
+    This step in the build process is skipped when running on a Windows host. A
+    known issue from the 1.6 release.
+- Platform Issues
+  - arm/juno: System suspend from Linux does not function as documented in the
+    user guide
+
+    Following the instructions provided in the user guide document does not
+    result in the platform entering system suspend state as expected. A message
+    relating to the hdlcd driver failing to suspend will be emitted on the Linux
+    terminal.
+
+  - mediatek/mt6795: This platform does not build in this release
+
+## [2.1.0](https://review.trustedfirmware.org/plugins/gitiles/TF-A/trusted-firmware-a/+/refs/tags/v2.0..refs/tags/v2.1) (2019-03-29)
+
+### New Features
+
+- Architecture
+
+  - Support for ARMv8.3 pointer authentication in the normal and secure worlds
+
+    The use of pointer authentication in the normal world is enabled whenever
+    architectural support is available, without the need for additional build
+    flags.
+
+    Use of pointer authentication in the secure world remains an experimental
+    configuration at this time. Using both the `ENABLE_PAUTH` and
+    `CTX_INCLUDE_PAUTH_REGS` build flags, pointer authentication can be enabled
+    in EL3 and S-EL1/0.
+
+    See the {ref}`Firmware Design` document for additional details on the use of
+    pointer authentication.
+
+  - Enable Data Independent Timing (DIT) in EL3, where supported
+
+- Build System
+
+  - Support for BL-specific build flags
+
+  - Support setting compiler target architecture based on `ARM_ARCH_MINOR` build
+    option.
+
+  - New `RECLAIM_INIT_CODE` build flag:
+
+    A significant amount of the code used for the initialization of BL31 is not
+    needed again after boot time. In order to reduce the runtime memory
+    footprint, the memory used for this code can be reclaimed after
+    initialization.
+
+    Certain boot-time functions were marked with the `__init` attribute to
+    enable this reclamation.

+
+  - Add platform-specific jump table list
+
+  - Allow patching of romlib functions
+
+    This change allows patching of functions in the romlib. This can be done by
+    adding "patch" at the end of the jump table entry for the function that
+    needs to be patched in the file jmptbl.i.
+
+- Library Code
+
+  - Support non-LPAE-enabled MMU tables in AArch32

+
+    Building a combined BL1 and ROMLIB binary file with the correct page
+    alignment is now supported on the Juno platform. When `USE_ROMLIB` is set
+    for Juno, it generates the combined file `bl1_romlib.bin` which needs to be

+- Position-Independent Executable (PIE)
+
+  PIE support has initially been added to BL31. The `ENABLE_PIE` build flag is
+  used to enable or disable this functionality as required.
+
+- Secure Partition Manager
+
+  - New SPM implementation based on SPCI Alpha 1 draft specification
+
+    A new version of SPM has been implemented, based on the SPCI (Secure
+    Partition Client Interface) and SPRT (Secure Partition Runtime) draft
+    specifications.
+
+    The new implementation is a prototype that is expected to undergo intensive
+    rework as the specifications change. It has basic support for multiple
+    Secure Partitions and Resource Descriptions.
+
+    The older version of SPM, based on MM (ARM Management Mode Interface
+    Specification), is still present in the codebase. A new build flag, `SPM_MM`
+    has been added to allow selection of the desired implementation. This flag
+    defaults to 1, selecting the MM-based implementation.
+
+- Security
+
+  - Spectre Variant-1 mitigations (`CVE-2017-5753`)
+
+  - Use Speculation Store Bypass Safe (SSBS) functionality where available
+
+    Provides mitigation against `CVE-2018-19440` (Not saving x0 to x3 registers
+    can leak information from one Normal World SMC client to another)
+
+### Changed
+
+- Build System
+

+  - "Warnings as errors" (Werror) can be disabled using `E=0`
+  - Support totally quiet output with `-s` flag
+  - Support passing options to checkpatch using `CHECKPATCH_OPTS=<opts>`
+  - Invoke host compiler with `HOSTCC / HOSTCCFLAGS` instead of `CC / CFLAGS`
+  - Make device tree pre-processing similar to U-boot/Linux by:
+    - Creating separate `CPPFLAGS` for DT preprocessing so that compiler options
+      specific to it can be accommodated.
+    - Replacing `CPP` with `PP` for DT pre-processing
+
+- CPU Support
+
+  - Errata report function definition is now mandatory for CPU support files
+
+    CPU operation files must now define a `<name>_errata_report` function to
+    print errata status. This is no longer a weak reference.
+
+- Documentation
+
+  - Migrated some content from GitHub wiki to `docs/` directory
+  - Security advisories now have CVE links
+  - Updated copyright guidelines
+
+- Drivers
+
+  - console: The `MULTI_CONSOLE_API` framework has been rewritten in C

+    values at runtime.
+
+  - delay_timer: Check that the Generic Timer extension is present
+
+  - mmc: Increase command reply timeout to 10 milliseconds
+

+    master branch (r345645)
+  - cpu: Updated macro that checks need for `CVE-2017-5715` mitigation
+  - libc: Made setjmp and longjmp C standard compliant
+  - libc: Allowed overriding the default libc (use `OVERRIDE_LIBC`)
+  - libc: Moved setjmp and longjmp to the `libc/` directory
+
+- Platforms
+
+  - Removed Mbed TLS dependency from plat_bl_common.c
+
+  - arm: Removed unused `ARM_MAP_BL_ROMLIB` macro
+
+  - arm: Removed `ARM_BOARD_OPTIMISE_MEM` feature and build flag
+
+  - arm: Moved several components into `drivers/` directory
+
+    This affects the SDS, SCP, SCPI, MHU and SCMI components
+
+  - arm/juno: Increased maximum BL2 image size to `0xF000`
+
+    This change was required to accommodate a larger `libfdt` library
+
+- SCMI
+
+  - Optimized bakery locks when hardware-assisted coherency is enabled using the
+    `HW_ASSISTED_COHERENCY` build flag
+
+- SDEI
+
+  - Added support for unconditionally resuming secure world execution after {{
+    SDEI }} event processing completes
+
+    {{ SDEI }} interrupts, although targeting EL3, occur on behalf of the
+    non-secure world, and may have higher priority than secure world interrupts.
+    Therefore they might preempt secure execution and yield execution to the
+    non-secure {{ SDEI }} handler. Upon completion of {{ SDEI }} event handling,
+    resume secure execution if it was preempted.
+
+- Translation Tables (XLAT)
+
+  - Dynamically detect need for `Common not Private (TTBRn_ELx.CnP)` bit
+
+    Properly handle the case where `ARMv8.2-TTCNP` is implemented in a CPU that
+    does not implement all mandatory v8.2 features (and so must claim to
+    implement a lower architecture version).
+
+### Resolved Issues
+
+- Architecture
+  - Incorrect check for SSBS feature detection
+  - Unintentional register clobber in AArch32 reset_handler function
+- Build System
+  - Dependency issue during DTB image build
+  - Incorrect variable expansion in Arm platform makefiles
+  - Building on Windows with verbose mode (`V=1`) enabled is broken
+  - AArch32 compilation flags is missing `$(march32-directive)`
+- BL-Specific Issues
+  - bl2: `uintptr_t is not defined` error when `BL2_IN_XIP_MEM` is defined
+  - bl2: Missing prototype warning in `bl2_arch_setup`
+  - bl31: Omission of Global Offset Table (GOT) section
+- Code Quality Issues
+  - Multiple MISRA compliance issues
+  - Potential NULL pointer dereference (Coverity-detected)
+- Drivers
+  - mmc: Local declaration of `scr` variable causes a cache issue when
+    invalidating after the read DMA transfer completes
+  - mmc: `ACMD41` does not send voltage information during initialization,
+    resulting in the command being treated as a query. This prevents the command
+    from initializing the controller.
+  - mmc: When checking device state using `mmc_device_state()` there are no
+    retries attempted in the event of an error
+  - ccn: Incorrect Region ID calculation for RN-I nodes
+  - console: `Fix MULTI_CONSOLE_API` when used as a crash console
+  - partition: Improper NULL checking in gpt.c
+  - partition: Compilation failure in `VERBOSE` mode (`V=1`)
+- Library Code
+  - common: Incorrect check for Address Authentication support
+
+  - xlat: Fix XLAT_V1 / XLAT_V2 incompatibility
+
+    The file `arm_xlat_tables.h` has been renamed to `xlat_tables_compat.h` and
+    has been moved to a common folder. This header can be used to guarantee
+    compatibility, as it includes the correct header based on
+    `XLAT_TABLES_LIB_V2`.
+
+  - xlat: armclang unused-function warning on `xlat_clean_dcache_range`
+
+  - xlat: Invalid `mm_cursor` checks in `mmap_add` and `mmap_add_ctx`
+
+  - sdei: Missing `context.h` header
+- Platforms
+  - common: Missing prototype warning for `plat_log_get_prefix`
+
+  - arm: Insufficient maximum BL33 image size
+
+  - arm: Potential memory corruption during BL2-BL31 transition
+
+    On Arm platforms, the BL2 memory can be overlaid by BL31/BL32. The memory
+    descriptors describing the list of executable images are created in BL2 R/W
+    memory, which could be possibly corrupted later on by BL31/BL32 due to
+    overlay. This patch creates a reserved location in SRAM for these
+    descriptors and are copied over by BL2 before handing over to next BL image.
+
+  - juno: Invalid behaviour when `CSS_USE_SCMI_SDS_DRIVER` is not set
+
+    In `juno_pm.c` the `css_scmi_override_pm_ops` function was used regardless
+    of whether the build flag was set. The original behaviour has been restored
+    in the case where the build flag is not set.
+- Tools
+  - fiptool: Incorrect UUID parsing of blob parameters
+  - doimage: Incorrect object rules in Makefile
+
+### Deprecations
+
+- Common Code
+  - `plat_crash_console_init` function
+  - `plat_crash_console_putc` function
+  - `plat_crash_console_flush` function
+  - `finish_console_register` macro
+- AArch64-specific Code
+  - helpers: `get_afflvl_shift`
+  - helpers: `mpidr_mask_lower_afflvls`
+  - helpers: `eret`
+- Secure Partition Manager (SPM)
+  - Boot-info structure
+
+### Known Issues
+
+- Build System Issues
+  - dtb: DTB creation not supported when building on a Windows host.
+
+    This step in the build process is skipped when running on a Windows host. A
+    known issue from the 1.6 release.
+- Platform Issues
+  - arm/juno: System suspend from Linux does not function as documented in the
+    user guide
+
+    Following the instructions provided in the user guide document does not
+    result in the platform entering system suspend state as expected. A message
+    relating to the hdlcd driver failing to suspend will be emitted on the Linux
+    terminal.
+
+  - arm/juno: The firmware update use-cases do not work with motherboard
+    firmware version \< v1.5.0 (the reset reason is not preserved). The Linaro
+    18.04 release has MB v1.4.9. The MB v1.5.0 is available in Linaro 18.10
+    release.
+
+  - mediatek/mt6795: This platform does not build in this release
+
+## [2.0.0](https://review.trustedfirmware.org/plugins/gitiles/TF-A/trusted-firmware-a/+/refs/tags/v1.6..refs/tags/v2.0) (2018-10-02)
+
+### New Features
+
+- Removal of a number of deprecated APIs
+
+  - A new Platform Compatibility Policy document has been created which
+    references a wiki page that maintains a listing of deprecated interfaces and
+    the release after which they will be removed.
+  - All deprecated interfaces except the MULTI_CONSOLE_API have been removed
+    from the code base.
+  - Various Arm and partner platforms have been updated to remove the use of
+    removed APIs in this release.
+  - This release is otherwise unchanged from 1.6 release
+
+### Issues resolved since last release
+
+- No issues known at 1.6 release resolved in 2.0 release
+
+### Known Issues
+
+- DTB creation not supported when building on a Windows host. This step in the
+  build process is skipped when running on a Windows host. Known issue from 1.6
+  version.
+- As a result of removal of deprecated interfaces the Nvidia Tegra, Marvell
+  Armada 8K and MediaTek MT6795 platforms do not build in this release. Also
+  MediaTek MT8173, NXP QorIQ LS1043A, NXP i.MX8QX, NXP i.MX8QMa, Rockchip
+  RK3328, Rockchip RK3368 and Rockchip RK3399 platforms have not been confirmed
+  to be working after the removal of the deprecated interfaces although they do
+  build.
+
+## [1.6.0](https://review.trustedfirmware.org/plugins/gitiles/TF-A/trusted-firmware-a/+/refs/tags/v1.5..refs/tags/v1.6) (2018-09-21)
+
+### New Features
+
+- Addressing Speculation Security Vulnerabilities
+
+  - Implement static workaround for CVE-2018-3639 for AArch32 and AArch64
+  - Add support for dynamic mitigation for CVE-2018-3639
+  - Implement dynamic mitigation for CVE-2018-3639 on Cortex-A76
+  - Ensure {{ SDEI }} handler executes with CVE-2018-3639 mitigation enabled
+
+- Introduce RAS handling on AArch64
+
+  - Some RAS extensions are mandatory for Armv8.2 CPUs, with others mandatory
+    for Armv8.4 CPUs however, all extensions are also optional extensions to the
+    base Armv8.0 architecture.
+  - The Armv8 RAS Extensions introduced Standard Error Records which are a set
+    of standard registers to configure RAS node policy and allow RAS Nodes to
+    record and expose error information for error handling agents.
+  - Capabilities are provided to support RAS Node enumeration and iteration
+    along with individual interrupt registrations and fault injections support.
+  - Introduce handlers for Uncontainable errors, Double Faults and EL3 External
+    Aborts
+
+- Enable Memory Partitioning And Monitoring (MPAM) for lower EL's
+
+  - Memory Partitioning And Monitoring is an Armv8.4 feature that enables
+    various memory system components and resources to define partitions.
+    Software running at various ELs can then assign themselves to the desired
+    partition to control their performance aspects.
+  - When ENABLE_MPAM_FOR_LOWER_ELS is set to 1, EL3 allows lower ELs to access
+    their own MPAM registers without trapping to EL3. This patch however,
+    doesn't make use of partitioning in EL3; platform initialisation code should
+    configure and use partitions in EL3 if required.
+
+- Introduce ROM Lib Feature
+
+  - Support combining several libraries into a self-called "romlib" image, that
+    may be shared across images to reduce memory footprint. The romlib image is
+    stored in ROM but is accessed through a jump-table that may be stored in
+    read-write memory, allowing for the library code to be patched.
+
+- Introduce Backtrace Feature
+
+  - This function displays the backtrace, the current EL and security state to
+    allow a post-processing tool to choose the right binary to interpret the
+    dump.
+  - Print backtrace in assert() and panic() to the console.
+
+- Code hygiene changes and alignment with MISRA C-2012 guideline with fixes
+  addressing issues complying to the following rules:
+
+  - MISRA rules 4.9, 5.1, 5.3, 5.7, 8.2-8.5, 8.8, 8.13, 9.3, 10.1, 10.3-10.4,
+    10.8, 11.3, 11.6, 12.1, 14.4, 15.7, 16.1-16.7, 17.7-17.8, 20.7, 20.10,
+    20.12, 21.1, 21.15, 22.7
+  - Clean up the usage of void pointers to access symbols
+  - Increase usage of static qualifier to locally used functions and data
+  - Migrated to use of u_register_t for register read/write to better match
+    AArch32 and AArch64 type sizes
+  - Use int-ll64 for both AArch32 and AArch64 to assist in consistent format
+    strings between architectures
+  - Clean up TF-A libc by removing non arm copyrighted implementations and
+    replacing them with modified FreeBSD and SCC implementations
+
+- Various changes to support Clang linker and assembler
+
+  - The clang assembler/preprocessor is used when Clang is selected. However,
+    the clang linker is not used because it is unable to link TF-A objects due
+    to immaturity of clang linker functionality at this time.
+
+- Refactor support APIs into Libraries
+
+  - Evolve libfdt, mbed TLS library and standard C library sources as proper
+    libraries that TF-A may be linked against.
+
+- CPU Enhancements
+
+  - Add CPU support for Cortex-Ares and Cortex-A76
+  - Add AMU support for Cortex-Ares
+  - Add initial CPU support for Cortex-Deimos
+  - Add initial CPU support for Cortex-Helios
+  - Implement dynamic mitigation for CVE-2018-3639 on Cortex-A76
+  - Implement Cortex-Ares erratum 1043202 workaround
+  - Implement DSU erratum 936184 workaround
+  - Check presence of fix for errata 843419 in Cortex-A53
+  - Check presence of fix for errata 835769 in Cortex-A53
+
+- Translation Tables Enhancements
+
+  - The xlat v2 library has been refactored in order to be reused by different
+    TF components at different EL's including the addition of EL2. Some
+    refactoring to make the code more generic and less specific to TF, in order
+    to reuse the library outside of this project.
+
+- SPM Enhancements
+
+  - General cleanups and refactoring to pave the way to multiple partitions
+    support
+
+- SDEI Enhancements
+
+  - Allow platforms to define explicit events
+  - Determine client EL from NS context's SCR_EL3
+  - Make dispatches synchronous
+  - Introduce jump primitives for BL31
+  - Mask events after CPU wakeup in {{ SDEI }} dispatcher to conform to the
+    specification
+
+- Misc TF-A Core Common Code Enhancements
+
+  - Add support for eXecute In Place (XIP) memory in BL2
+  - Add support for the SMC Calling Convention 2.0
+  - Introduce External Abort handling on AArch64 External Abort routed to EL3
+    was reported as an unhandled exception and caused a panic. This change
+    enables Trusted Firmware-A to handle External Aborts routed to EL3.
+  - Save value of ACTLR_EL1 implementation-defined register in the CPU context
+    structure rather than forcing it to 0.
+  - Introduce ARM_LINUX_KERNEL_AS_BL33 build option, which allows BL31 to
+    directly jump to a Linux kernel. This makes for a quicker and simpler boot
+    flow, which might be useful in some test environments.
+  - Add dynamic configurations for BL31, BL32 and BL33 enabling support for
+    Chain of Trust (COT).
+  - Make TF UUID RFC 4122 compliant
+

+
+### Issues resolved since last release
+
+- No issues known at 1.5 release resolved in 1.6 release
+
+### Known Issues
+
+- DTB creation not supported when building on a Windows host. This step in the
+  build process is skipped when running on a Windows host. Known issue from 1.5
+  version.
+
+## [1.5.0](https://review.trustedfirmware.org/plugins/gitiles/TF-A/trusted-firmware-a/+/refs/tags/v1.4..refs/tags/v1.5) (2018-03-20)
+
+### New features
+
+- Added new firmware support to enable RAS (Reliability, Availability, and
+  Serviceability) functionality.
+
+  - Secure Partition Manager (SPM): A Secure Partition is a software execution
+    environment instantiated in S-EL0 that can be used to implement simple
+    management and security services. The SPM is the firmware component that is
+    responsible for managing a Secure Partition.
+
+  - SDEI dispatcher: Support for interrupt-based {{ SDEI }} events and all
+    interfaces as defined by the {{ SDEI }} specification v1.0, see
+    [SDEI Specification]
+
+  - Exception Handling Framework (EHF): Framework that allows dispatching of EL3
+    interrupts to their registered handlers which are registered based on their
+    priorities. Facilitates firmware-first error handling policy where
+    asynchronous exceptions may be routed to EL3.
+
+    Integrated the TSPD with EHF.
+
+- Updated PSCI support:
+
+  - Implemented PSCI v1.1 optional features `MEM_PROTECT` and `SYSTEM_RESET2`.
+    The supported PSCI version was updated to v1.1.
+
+  - Improved PSCI STAT timestamp collection, including moving accounting for
+    retention states to be inside the locks and fixing handling of wrap-around
+    when calculating residency in AArch32 execution state.
+
+  - Added optional handler for early suspend that executes when suspending to a
+    power-down state and with data caches enabled.
+
+    This may provide a performance improvement on platforms where it is safe to
+    perform some or all of the platform actions from `pwr_domain_suspend` with
+    the data caches enabled.
+
+- Enabled build option, BL2_AT_EL3, for BL2 to allow execution at EL3 without
+  any dependency on TF BL1.
+
+  This allows platforms which already have a non-TF Boot ROM to directly load
+  and execute BL2 and subsequent BL stages without need for BL1. This was not
+  previously possible because BL2 executes at S-EL1 and cannot jump straight to
+  EL3.
+
+- Implemented support for SMCCC v1.1, including `SMCCC_VERSION` and
+  `SMCCC_ARCH_FEATURES`.
+
+  Additionally, added support for `SMCCC_VERSION` in PSCI features to enable
+  discovery of the SMCCC version via PSCI feature call.
+
+- Added Dynamic Configuration framework which enables each of the boot loader
+  stages to be dynamically configured at runtime if required by the platform.
+  The boot loader stage may optionally specify a firmware configuration file
+  and/or hardware configuration file that can then be shared with the next boot
+  loader stage.
+
+  Introduced a new BL handover interface that essentially allows passing of 4
+  arguments between the different BL stages.
+
+  Updated cert_create and fip_tool to support the dynamic configuration files.
+  The COT also updated to support these new files.
+
+- Code hygiene changes and alignment with MISRA guideline:
+
+  - Fix use of undefined macros.
+  - Achieved compliance with Mandatory MISRA coding rules.
+  - Achieved compliance for following Required MISRA rules for the default build
+    configurations on FVP and Juno platforms : 7.3, 8.3, 8.4, 8.5 and 8.8.
+
+- Added support for Armv8.2-A architectural features:
+
+  - Updated translation table set-up to set the CnP (Common not Private) bit for
+    secure page tables so that multiple PEs in the same Inner Shareable domain
+    can use the same translation table entries for a given stage of translation
+    in a particular translation regime.
+  - Extended the supported values of ID_AA64MMFR0_EL1.PARange to include the
+    52-bit Physical Address range.
+  - Added support for the Scalable Vector Extension to allow Normal world
+    software to access SVE functionality but disable access to SVE, SIMD and
+    floating point functionality from the Secure world in order to prevent
+    corruption of the Z-registers.
+
+- Added support for Armv8.4-A architectural feature Activity Monitor Unit (AMU)
+
+  extensions.
+
+  In addition to the v8.4 architectural extension, AMU support on Cortex-A75 was
+  implemented.
+
+- Enhanced OP-TEE support to enable use of pageable OP-TEE image. The Arm
+  standard platforms are updated to load up to 3 images for OP-TEE; header,
+  pager image and paged image.
+
+  The chain of trust is extended to support the additional images.
+
+- Enhancements to the translation table library:
+
+  - Introduced APIs to get and set the memory attributes of a region.
+  - Added support to manage both privilege levels in translation regimes that
+    describe translations for 2 Exception levels, specifically the EL1&0
+    translation regime, and extended the memory map region attributes to include
+    specifying Non-privileged access.
+  - Added support to specify the granularity of the mappings of each region, for
+    instance a 2MB region can be specified to be mapped with 4KB page tables
+    instead of a 2MB block.
+  - Disabled the higher VA range to avoid unpredictable behaviour if there is an
+    attempt to access addresses in the higher VA range.
+  - Added helpers for Device and Normal memory MAIR encodings that align with
+    the Arm Architecture Reference Manual for Armv8-A (Arm DDI0487B.b).
+  - Code hygiene including fixing type length and signedness of constants,
+    refactoring of function to enable the MMU, removing all instances where the
+    virtual address space is hardcoded and added comments that document
+    alignment needed between memory attributes and attributes specified in
+    TCR_ELx.
+
+- Updated GIC support:
+
+  - Introduce new APIs for GICv2 and GICv3 that provide the capability to
+    specify interrupt properties rather than list of interrupt numbers alone.
+    The Arm platforms and other upstream platforms are migrated to use interrupt
+    properties.
+
+  - Added helpers to save / restore the GICv3 context, specifically the
+    Distributor and Redistributor contexts and architectural parts of the ITS
+    power management. The Distributor and Redistributor helpers also support the
+    implementation-defined part of GIC-500 and GIC-600.
+
+    Updated the Arm FVP platform to save / restore the GICv3 context on system
+    suspend / resume as an example of how to use the helpers.
+
+    Introduced a new TZC secured DDR carve-out for use by Arm platforms for
+    storing EL3 runtime data such as the GICv3 register context.
+
+- Added support for Armv7-A architecture via build option ARM_ARCH_MAJOR=7. This
+  includes following features:
+
+  - Updates GICv2 driver to manage GICv1 with security extensions.
+  - Software implementation for 32bit division.
+  - Enabled use of generic timer for platforms that do not set
+    ARM_CORTEX_Ax=yes.
+  - Support for Armv7-A Virtualization extensions \[DDI0406C_C\].
+  - Support for both Armv7-A platforms that only have 32-bit addressing and
+    Armv7-A platforms that support large page addressing.
+  - Included support for following Armv7 CPUs: Cortex-A12, Cortex-A17,
+    Cortex-A7, Cortex-A5, Cortex-A9, Cortex-A15.
+  - Added support in QEMU for Armv7-A/Cortex-A15.
+
+- Enhancements to Firmware Update feature:
+
+  - Updated the FWU documentation to describe the additional images needed for
+    Firmware update, and how they are used for both the Juno platform and the
+    Arm FVP platforms.
+
+- Enhancements to Trusted Board Boot feature:
+
+  - Added support to cert_create tool for RSA PKCS1# v1.5 and SHA384, SHA512 and
+    SHA256.
+  - For Arm platforms added support to use ECDSA keys.
+  - Enhanced the mbed TLS wrapper layer to include support for both RSA and
+    ECDSA to enable runtime selection between RSA and ECDSA keys.
+
+- Added support for secure interrupt handling in AArch32 sp_min, hardcoded to
+  only handle FIQs.
+
+- Added support to allow a platform to load images from multiple boot sources,
+  for example from a second flash drive.
+
+- Added a logging framework that allows platforms to reduce the logging level at
+  runtime and additionally the prefix string can be defined by the platform.
+
+- Further improvements to register initialisation:
+
+  - Control register PMCR_EL0 / PMCR is set to prohibit cycle counting in the
+    secure world. This register is added to the list of registers that are saved
+    and restored during world switch.
+  - When EL3 is running in AArch32 execution state, the Non-secure version of
+    SCTLR is explicitly initialised during the warmboot flow rather than relying
+    on the hardware to set the correct reset values.
+
+- Enhanced support for Arm platforms:
+
+  - Introduced driver for Shared-Data-Structure (SDS) framework which is used
+    for communication between SCP and the AP CPU, replacing Boot-Over_MHU (BOM)
+    protocol.
+
+    The Juno platform is migrated to use SDS with the SCMI support added in v1.3
+    and is set as default.
+
+    The driver can be found in the plat/arm/css/drivers folder.
+
+  - Improved memory usage by only mapping TSP memory region when the TSPD has
+    been included in the build. This reduces the memory footprint and avoids
+    unnecessary memory being mapped.
+
+  - Updated support for multi-threading CPUs for FVP platforms - always check
+    the MT field in MPDIR and access the bit fields accordingly.
+
+  - Support building for platforms that model DynamIQ configuration by
+    implementing all CPUs in a single cluster.
+
+  - Improved nor flash driver, for instance clearing status registers before
+    sending commands. Driver can be found plat/arm/board/common folder.
+
+- Enhancements to QEMU platform:
+
+  - Added support for TBB.
+  - Added support for using OP-TEE pageable image.
+  - Added support for LOAD_IMAGE_V2.
+  - Migrated to use translation table library v2 by default.
+  - Added support for SEPARATE_CODE_AND_RODATA.
+
+- Applied workarounds CVE-2017-5715 on Arm Cortex-A57, -A72, -A73 and -A75, and
+  for Armv7-A CPUs Cortex-A9, -A15 and -A17.
+
+- Applied errata workaround for Arm Cortex-A57: 859972.
+
+- Applied errata workaround for Arm Cortex-A72: 859971.
+
+- Added support for Poplar 96Board platform.
+
+- Added support for Raspberry Pi 3 platform.
+
+- Added Call Frame Information (CFI) assembler directives to the vector entries
+  which enables debuggers to display the backtrace of functions that triggered a
+  synchronous abort.
+
+- Added ability to build dtb.
+
+- Added support for pre-tool (cert_create and fiptool) image processing enabling
+  compression of the image files before processing by cert_create and fiptool.
+
+  This can reduce fip size and may also speed up loading of images. The image
+  verification will also get faster because certificates are generated based on
+  compressed images.
+
+  Imported zlib 1.2.11 to implement gunzip() for data compression.
+
+- Enhancements to fiptool:
+
+  - Enabled the fiptool to be built using Visual Studio.
+  - Added padding bytes at the end of the last image in the fip to be facilitate
+    transfer by DMA.
+
+### Issues resolved since last release
+
+- TF-A can be built with optimisations disabled (-O0).
+- Memory layout updated to enable Trusted Board Boot on Juno platform when
+  running TF-A in AArch32 execution mode (resolving [tf-issue#501]).
+
+### Known Issues
+
+- DTB creation not supported when building on a Windows host. This step in the
+  build process is skipped when running on a Windows host.
+
+## [1.4.0](https://review.trustedfirmware.org/plugins/gitiles/TF-A/trusted-firmware-a/+/refs/tags/v1.3..refs/tags/v1.4) (2017-07-07)
+
+### New features
+
+- Enabled support for platforms with hardware assisted coherency.
+
+  A new build option HW_ASSISTED_COHERENCY allows platforms to take advantage of
+  the following optimisations:
+
+  - Skip performing cache maintenance during power-up and power-down.
+  - Use spin-locks instead of bakery locks.
+  - Enable data caches early on warm-booted CPUs.
+
+- Added support for Cortex-A75 and Cortex-A55 processors.
+
+  Both Cortex-A75 and Cortex-A55 processors use the Arm DynamIQ Shared Unit
+  (DSU). The power-down and power-up sequences are therefore mostly managed in
+  hardware, reducing complexity of the software operations.
+
+- Introduced Arm GIC-600 driver.
+
+  Arm GIC-600 IP complies with Arm GICv3 architecture. For FVP platforms, the
+  GIC-600 driver is chosen when FVP_USE_GIC_DRIVER is set to FVP_GIC600.
+
+- Updated GICv3 support:
+
+  - Introduced power management APIs for GICv3 Redistributor. These APIs allow
+    platforms to power down the Redistributor during CPU power on/off. Requires
+    the GICv3 implementations to have power management operations.
+
+    Implemented the power management APIs for FVP.
+
+  - GIC driver data is flushed by the primary CPU so that secondary CPU do not
+    read stale GIC data.
+
+- Added support for Arm System Control and Management Interface v1.0 (SCMI).
+
+  The SCMI driver implements the power domain management and system power
+  management protocol of the SCMI specification (Arm DEN 0056ASCMI) for
+  communicating with any compliant power controller.
+
+  Support is added for the Juno platform. The driver can be found in the
+  plat/arm/css/drivers folder.
+
+- Added support to enable pre-integration of TBB with the Arm TrustZone
+  CryptoCell product, to take advantage of its hardware Root of Trust and crypto
+  acceleration services.
+
+- Enabled Statistical Profiling Extensions for lower ELs.
+
+  The firmware support is limited to the use of SPE in the Non-secure state and
+  accesses to the SPE specific registers from S-EL1 will trap to EL3.
+
+  The SPE are architecturally specified for AArch64 only.
+
+- Code hygiene changes aligned with MISRA guidelines:
+
+  - Fixed signed / unsigned comparison warnings in the translation table
+    library.
+  - Added U(\_x) macro and together with the existing ULL(\_x) macro fixed some
+    of the signed-ness defects flagged by the MISRA scanner.
+
+- Enhancements to Firmware Update feature:
+
+  - The FWU logic now checks for overlapping images to prevent execution of
+    unauthenticated arbitrary code.
+  - Introduced new FWU_SMC_IMAGE_RESET SMC that changes the image loading state
+    machine to go from COPYING, COPIED or AUTHENTICATED states to RESET state.
+    Previously, this was only possible when the authentication of an image
+    failed or when the execution of the image finished.
+  - Fixed integer overflow which addressed TFV-1: Malformed Firmware Update SMC
+    can result in copy of unexpectedly large data into secure memory.
+
+- Introduced support for Arm Compiler 6 and LLVM (clang).
+
+  TF-A can now also be built with the Arm Compiler 6 or the clang compilers. The
+  assembler and linker must be provided by the GNU toolchain.
+
+  Tested with Arm CC 6.7 and clang 3.9.x and 4.0.x.
+
+- Memory footprint improvements:
+
+  - Introduced `tf_snprintf`, a reduced version of `snprintf` which has support
+    for a limited set of formats.
+
+    The mbedtls driver is updated to optionally use `tf_snprintf` instead of
+    `snprintf`.
+
+  - The `assert()` is updated to no longer print the function name, and
+    additional logging options are supported via an optional platform define
+    `PLAT_LOG_LEVEL_ASSERT`, which controls how verbose the assert output is.
+
+- Enhancements to TF-A support when running in AArch32 execution state:
+
+  - Support booting SP_MIN and BL33 in AArch32 execution mode on Juno. Due to
+    hardware limitations, BL1 and BL2 boot in AArch64 state and there is
+    additional trampoline code to warm reset into SP_MIN in AArch32 execution
+    state.
+  - Added support for Arm Cortex-A53/57/72 MPCore processors including the
+    errata workarounds that are already implemented for AArch64 execution state.
+  - For FVP platforms, added AArch32 Trusted Board Boot support, including the
+    Firmware Update feature.
+
+- Introduced Arm SiP service for use by Arm standard platforms.
+
+  - Added new Arm SiP Service SMCs to enable the Non-secure world to read PMF
+    timestamps.
+
+    Added PMF instrumentation points in TF-A in order to quantify the overall
+    time spent in the PSCI software implementation.
+
+  - Added new Arm SiP service SMC to switch execution state.
+
+    This allows the lower exception level to change its execution state from
+    AArch64 to AArch32, or vice verse, via a request to EL3.
+
+- Migrated to use SPDX\[0\] license identifiers to make software license
+  auditing simpler.
+
+  \:::\{note} Files that have been imported by FreeBSD have not been modified.
+  \:::
+
+  \[0\]: <https://spdx.org/>
+
+- Enhancements to the translation table library:
+
+  - Added version 2 of translation table library that allows different
+    translation tables to be modified by using different 'contexts'. Version 1
+    of the translation table library only allows the current EL's translation
+    tables to be modified.
+
+    Version 2 of the translation table also added support for dynamic regions;
+    regions that can be added and removed dynamically whilst the MMU is enabled.
+    Static regions can only be added or removed before the MMU is enabled.
+
+    The dynamic mapping functionality is enabled or disabled when compiling by
+    setting the build option PLAT_XLAT_TABLES_DYNAMIC to 1 or 0. This can be
+    done per-image.
+
+  - Added support for translation regimes with two virtual address spaces such
+    as the one shared by EL1 and EL0.
+
+    The library does not support initializing translation tables for EL0
+    software.
+
+  - Added support to mark the translation tables as non-cacheable using an
+    additional build option `XLAT_TABLE_NC`.
+
+- Added support for GCC stack protection. A new build option
+  ENABLE_STACK_PROTECTOR was introduced that enables compilation of all BL
+  images with one of the GCC -fstack-protector-\* options.
+
+  A new platform function plat_get_stack_protector_canary() was introduced that
+  returns a value used to initialize the canary for stack corruption detection.
+  For increased effectiveness of protection platforms must provide an
+  implementation that returns a random value.
+
+- Enhanced support for Arm platforms:
+
+  - Added support for multi-threading CPUs, indicated by `MT` field in MPDIR. A
+    new build flag `ARM_PLAT_MT` is added, and when enabled, the functions
+    accessing MPIDR assume that the `MT` bit is set for the platform and access
+    the bit fields accordingly.
+
+    Also, a new API `plat_arm_get_cpu_pe_count` is added when `ARM_PLAT_MT` is
+    enabled, returning the Processing Element count within the physical CPU
+    corresponding to `mpidr`.
+
+  - The Arm platforms migrated to use version 2 of the translation tables.
+
+  - Introduced a new Arm platform layer API `plat_arm_psci_override_pm_ops`
+    which allows Arm platforms to modify `plat_arm_psci_pm_ops` and therefore
+    dynamically define PSCI capability.
+
+  - The Arm platforms migrated to use IMAGE_LOAD_V2 by default.
+
+- Enhanced reporting of errata workaround status with the following policy:
+
+  - If an errata workaround is enabled:
+
+    - If it applies (i.e. the CPU is affected by the errata), an INFO message is
+      printed, confirming that the errata workaround has been applied.
+    - If it does not apply, a VERBOSE message is printed, confirming that the
+      errata workaround has been skipped.
+
+  - If an errata workaround is not enabled, but would have applied had it been,
+    a WARN message is printed, alerting that errata workaround is missing.
+
+- Added build options ARM_ARCH_MAJOR and ARM_ARM_MINOR to choose the
+  architecture version to target TF-A.
+
+- Updated the spin lock implementation to use the more efficient CAS (Compare
+  And Swap) instruction when available. This instruction was introduced in
+  Armv8.1-A.
+
+- Applied errata workaround for Arm Cortex-A53: 855873.
+
+- Applied errata workaround for Arm-Cortex-A57: 813419.
+
+- Enabled all A53 and A57 errata workarounds for Juno, both in AArch64 and
+  AArch32 execution states.
+
+- Added support for Socionext UniPhier SoC platform.
+
+- Added support for Hikey960 and Hikey platforms.
+
+- Added support for Rockchip RK3328 platform.
+
+- Added support for NVidia Tegra T186 platform.
+
+- Added support for Designware emmc driver.
+
+- Imported libfdt v1.4.2 that addresses buffer overflow in fdt_offset_ptr().
+
+- Enhanced the CPU operations framework to allow power handlers to be registered
+  on per-level basis. This enables support for future CPUs that have multiple
+  threads which might need powering down individually.
+
+- Updated register initialisation to prevent unexpected behaviour:
+
+  - Debug registers MDCR-EL3/SDCR and MDCR_EL2/HDCR are initialised to avoid
+    unexpected traps into the higher exception levels and disable secure
+    self-hosted debug. Additionally, secure privileged external debug on Juno is
+    disabled by programming the appropriate Juno SoC registers.
+  - EL2 and EL3 configurable controls are initialised to avoid unexpected traps
+    in the higher exception levels.
+  - Essential control registers are fully initialised on EL3 start-up, when
+    initialising the non-secure and secure context structures and when preparing
+    to leave EL3 for a lower EL. This gives better alignment with the Arm ARM
+    which states that software must initialise RES0 and RES1 fields with 0 / 1.
+
+- Enhanced PSCI support:
+
+  - Introduced new platform interfaces that decouple PSCI stat residency
+    calculation from PMF, enabling platforms to use alternative methods of
+    capturing timestamps.
+  - PSCI stat accounting performed for retention/standby states when requested
+    at multiple power levels.
+
+- Simplified fiptool to have a single linked list of image descriptors.
+
+- For the TSP, resolved corruption of pre-empted secure context by aborting any
+  pre-empted SMC during PSCI power management requests.
+
+### Issues resolved since last release
+
+- TF-A can be built with the latest mbed TLS version (v2.4.2). The earlier
+  version 2.3.0 cannot be used due to build warnings that the TF-A build system
+  interprets as errors.
+- TBBR, including the Firmware Update feature is now supported on FVP platforms
+  when running TF-A in AArch32 state.
+- The version of the AEMv8 Base FVP used in this release has resolved the issue
+  of the model executing a reset instead of terminating in response to a
+  shutdown request using the PSCI SYSTEM_OFF API.
+
+### Known Issues
+
+- Building TF-A with compiler optimisations disabled (-O0) fails.
+- Trusted Board Boot currently does not work on Juno when running Trusted
+  Firmware in AArch32 execution state due to error when loading the sp_min to
+  memory because of lack of free space available. See [tf-issue#501] for more
+  details.
+- The errata workaround for A53 errata 843419 is only available from binutils
+  2.26 and is not present in GCC4.9. If this errata is applicable to the
+  platform, please use GCC compiler version of at least 5.0. See [PR#1002] for
+  more details.
+
+## [1.3.0](https://review.trustedfirmware.org/plugins/gitiles/TF-A/trusted-firmware-a/+/refs/tags/v1.2..refs/tags/v1.3) (2016-10-13)
+
+### New features
+
+- Added support for running TF-A in AArch32 execution state.
+
+  The PSCI library has been refactored to allow integration with **EL3 Runtime
+  Software**. This is software that is executing at the highest secure privilege
+  which is EL3 in AArch64 or Secure SVC/Monitor mode in AArch32. See
+  \{ref}`PSCI Library Integration guide for Armv8-A AArch32 systems`.
+
+  Included is a minimal AArch32 Secure Payload, **SP-MIN**, that illustrates the
+  usage and integration of the PSCI library with EL3 Runtime Software running in
+  AArch32 state.
+
+  Booting to the BL1/BL2 images as well as booting straight to the Secure
+  Payload is supported.
+
+- Improvements to the initialization framework for the PSCI service and Arm
+  Standard Services in general.
+
+  The PSCI service is now initialized as part of Arm Standard Service
+  initialization. This consolidates the initializations of any Arm Standard
+  Service that may be added in the future.
+
+  A new function `get_arm_std_svc_args()` is introduced to get arguments
+  corresponding to each standard service and must be implemented by the EL3
+  Runtime Software.
+
+  For PSCI, a new versioned structure `psci_lib_args_t` is introduced to
+  initialize the PSCI Library. **Note** this is a compatibility break due to the
+  change in the prototype of `psci_setup()`.
+
+- To support AArch32 builds of BL1 and BL2, implemented a new, alternative
+  firmware image loading mechanism that adds flexibility.
+
+  The current mechanism has a hard-coded set of images and execution order
+  (BL31, BL32, etc). The new mechanism is data-driven by a list of image
+  descriptors provided by the platform code.
+
+  Arm platforms have been updated to support the new loading mechanism.
+
+  The new mechanism is enabled by a build flag (`LOAD_IMAGE_V2`) which is
+  currently off by default for the AArch64 build.
+
+  **Note** `TRUSTED_BOARD_BOOT` is currently not supported when `LOAD_IMAGE_V2`
+  is enabled.
+
+- Updated requirements for making contributions to TF-A.
+
+  Commits now must have a 'Signed-off-by:' field to certify that the
+  contribution has been made under the terms of the
+  {download}`Developer Certificate of Origin <../dco.txt>`.
+
+  A signed CLA is no longer required.
+
+  The {ref}`Contributor's Guide` has been updated to reflect this change.
+
+- Introduced Performance Measurement Framework (PMF) which provides support for
+  capturing, storing, dumping and retrieving time-stamps to measure the
+  execution time of critical paths in the firmware. This relies on defining
+  fixed sample points at key places in the code.
+
+- To support the QEMU platform port, imported libfdt v1.4.1 from
+  <https://git.kernel.org/pub/scm/utils/dtc/dtc.git>
+
+- Updated PSCI support:
+
+  - Added support for PSCI NODE_HW_STATE API for Arm platforms.
+  - New optional platform hook, `pwr_domain_pwr_down_wfi()`, in `plat_psci_ops`
+    to enable platforms to perform platform-specific actions needed to enter
+    powerdown, including the 'wfi' invocation.
+  - PSCI STAT residency and count functions have been added on Arm platforms by
+    using PMF.
+
+- Enhancements to the translation table library:
+
+  - Limited memory mapping support for region overlaps to only allow regions to
+    overlap that are identity mapped or have the same virtual to physical
+    address offset, and overlap completely but must not cover the same area.
+
+    This limitation will enable future enhancements without having to support
+    complex edge cases that may not be necessary.
+
+  - The initial translation lookup level is now inferred from the virtual
+    address space size. Previously, it was hard-coded.
+
+  - Added support for mapping Normal, Inner Non-cacheable, Outer Non-cacheable
+    memory in the translation table library.
+
+    This can be useful to map a non-cacheable memory region, such as a DMA
+    buffer.
+
+  - Introduced the MT_EXECUTE/MT_EXECUTE_NEVER memory mapping attributes to
+    specify the access permissions for instruction execution of a memory region.
+
+- Enabled support to isolate code and read-only data on separate memory pages,
+  allowing independent access control to be applied to each.
+
+- Enabled SCR_EL3.SIF (Secure Instruction Fetch) bit in BL1 and BL31 common
+  architectural setup code, preventing fetching instructions from non-secure
+  memory when in secure state.
+
+- Enhancements to FIP support:
+
+  - Replaced `fip_create` with `fiptool` which provides a more consistent and
+    intuitive interface as well as additional support to remove an image from a
+    FIP file.
+  - Enabled printing the SHA256 digest with info command, allowing quick
+    verification of an image within a FIP without having to extract the image
+    and running sha256sum on it.
+  - Added support for unpacking the contents of an existing FIP file into the
+    working directory.
+  - Aligned command line options for specifying images to use same naming
+    convention as specified by TBBR and already used in cert_create tool.
+
+- Refactored the TZC-400 driver to also support memory controllers that
+  integrate TZC functionality, for example Arm CoreLink DMC-500. Also added
+  DMC-500 specific support.
+
+- Implemented generic delay timer based on the system generic counter and
+  migrated all platforms to use it.
+
+- Enhanced support for Arm platforms:
+
+  - Updated image loading support to make SCP images (SCP_BL2 and SCP_BL2U)
+    optional.
+  - Enhanced topology description support to allow multi-cluster topology
+    definitions.
+  - Added interconnect abstraction layer to help platform ports select the right
+    interconnect driver, CCI or CCN, for the platform.
+  - Added support to allow loading BL31 in the TZC-secured DRAM instead of the
+    default secure SRAM.
+  - Added support to use a System Security Control (SSC) Registers Unit enabling
+    TF-A to be compiled to support multiple Arm platforms and then select one at
+    runtime.
+  - Restricted mapping of Trusted ROM in BL1 to what is actually needed by BL1
+    rather than entire Trusted ROM region.
+  - Flash is now mapped as execute-never by default. This increases security by
+    restricting the executable region to what is strictly needed.
+
+- Applied following erratum workarounds for Cortex-A57: 833471, 826977, 829520,
+  828024 and 826974.
+
+- Added support for Mediatek MT6795 platform.
+
+- Added support for QEMU virtualization Armv8-A target.
+
+- Added support for Rockchip RK3368 and RK3399 platforms.
+
+- Added support for Xilinx Zynq UltraScale+ MPSoC platform.
+
+- Added support for Arm Cortex-A73 MPCore Processor.
+
+- Added support for Arm Cortex-A72 processor.
+
+- Added support for Arm Cortex-A35 processor.
+
+- Added support for Arm Cortex-A32 MPCore Processor.
+
+- Enabled preloaded BL33 alternative boot flow, in which BL2 does not load BL33
+  from non-volatile storage and BL31 hands execution over to a preloaded BL33.
+  The User Guide has been updated with an example of how to use this option with
+  a bootwrapped kernel.
+
+- Added support to build TF-A on a Windows-based host machine.
+
+- Updated Trusted Board Boot prototype implementation:
+
+  - Enabled the ability for a production ROM with TBBR enabled to boot test
+    software before a real ROTPK is deployed (e.g. manufacturing mode). Added
+    support to use ROTPK in certificate without verifying against the platform
+    value when `ROTPK_NOT_DEPLOYED` bit is set.
+  - Added support for non-volatile counter authentication to the Authentication
+    Module to protect against roll-back.
+
+- Updated GICv3 support:
+
+  - Enabled processor power-down and automatic power-on using GICv3.
+  - Enabled G1S or G0 interrupts to be configured independently.
+  - Changed FVP default interrupt driver to be the GICv3-only driver. **Note**
+    the default build of TF-A will not be able to boot Linux kernel with GICv2
+    FDT blob.
+  - Enabled wake-up from CPU_SUSPEND to stand-by by temporarily re-routing
+    interrupts and then restoring after resume.
+
+### Issues resolved since last release
+
+### Known issues
+
+- The version of the AEMv8 Base FVP used in this release resets the model
+  instead of terminating its execution in response to a shutdown request using
+  the PSCI `SYSTEM_OFF` API. This issue will be fixed in a future version of the
+  model.
+- Building TF-A with compiler optimisations disabled (`-O0`) fails.
+- TF-A cannot be built with mbed TLS version v2.3.0 due to build warnings that
+  the TF-A build system interprets as errors.
+- TBBR is not currently supported when running TF-A in AArch32 state.
+
+## [1.2.0](https://review.trustedfirmware.org/plugins/gitiles/TF-A/trusted-firmware-a/+/refs/tags/v1.1..refs/tags/v1.2) (2015-12-22)
+
+### New features
+
+- The Trusted Board Boot implementation on Arm platforms now conforms to the
+  mandatory requirements of the TBBR specification.
+
+  In particular, the boot process is now guarded by a Trusted Watchdog, which
+  will reset the system in case of an authentication or loading error. On Arm
+  platforms, a secure instance of Arm SP805 is used as the Trusted Watchdog.
+
+  Also, a firmware update process has been implemented. It enables authenticated
+  firmware to update firmware images from external interfaces to SoC
+  Non-Volatile memories. This feature functions even when the current firmware
+  in the system is corrupt or missing; it therefore may be used as a recovery
+  mode.
+
+- Improvements have been made to the Certificate Generation Tool (`cert_create`)
+  as follows.
+
+  - Added support for the Firmware Update process by extending the Chain of
+    Trust definition in the tool to include the Firmware Update certificate and
+    the required extensions.
+  - Introduced a new API that allows one to specify command line options in the
+    Chain of Trust description. This makes the declaration of the tool's
+    arguments more flexible and easier to extend.
+  - The tool has been reworked to follow a data driven approach, which makes it
+    easier to maintain and extend.
+
+- Extended the FIP tool (`fip_create`) to support the new set of images involved
+  in the Firmware Update process.
+
+- Various memory footprint improvements. In particular:
+
+  - The bakery lock structure for coherent memory has been optimised.
+  - The mbed TLS SHA1 functions are not needed, as SHA256 is used to generate
+    the certificate signature. Therefore, they have been compiled out, reducing
+    the memory footprint of BL1 and BL2 by approximately 6 KB.
+  - On Arm development platforms, each BL stage now individually defines the
+    number of regions that it needs to map in the MMU.
+
+- Added the following new design documents:
+
+  - {ref}`Authentication Framework & Chain of Trust`
+  - {ref}`Firmware Update (FWU)`
+  - {ref}`CPU Reset`
+  - {ref}`PSCI Power Domain Tree Structure`
+
+- Applied the new image terminology to the code base and documentation, as
+  described in the {ref}`Image Terminology` document.
+
+- The build system has been reworked to improve readability and facilitate
+  adding future extensions.
+
+- On Arm standard platforms, BL31 uses the boot console during cold boot but
+  switches to the runtime console for any later logs at runtime. The TSP uses
+  the runtime console for all output.
+
+- Implemented a basic NOR flash driver for Arm platforms. It programs the device
+  using CFI (Common Flash Interface) standard commands.
+
+- Implemented support for booting EL3 payloads on Arm platforms, which reduces
+  the complexity of developing EL3 baremetal code by doing essential baremetal
+  initialization.
+
+- Provided separate drivers for GICv3 and GICv2. These expect the entire
+  software stack to use either GICv2 or GICv3; hybrid GIC software systems are
+  no longer supported and the legacy Arm GIC driver has been deprecated.
+
+- Added support for Juno r1 and r2. A single set of Juno TF-A binaries can run
+  on Juno r0, r1 and r2 boards. Note that this TF-A version depends on a Linaro
+  release that does *not* contain Juno r2 support.
+
+- Added support for MediaTek mt8173 platform.
+
+- Implemented a generic driver for Arm CCN IP.
+
+- Major rework of the PSCI implementation.
+
+  - Added framework to handle composite power states.
+  - Decoupled the notions of affinity instances (which describes the
+    hierarchical arrangement of cores) and of power domain topology, instead of
+    assuming a one-to-one mapping.
+  - Better alignment with version 1.0 of the PSCI specification.
+
+- Added support for the SYSTEM_SUSPEND PSCI API on Arm platforms. When invoked
+  on the last running core on a supported platform, this puts the system into a
+  low power mode with memory retention.
+
+- Unified the reset handling code as much as possible across BL stages. Also
+  introduced some build options to enable optimization of the reset path on
+  platforms that support it.
+
+- Added a simple delay timer API, as well as an SP804 timer driver, which is
+  enabled on FVP.
+
+- Added support for NVidia Tegra T210 and T132 SoCs.
+
+- Reorganised Arm platforms ports to greatly improve code shareability and
+  facilitate the reuse of some of this code by other platforms.
+
+- Added support for Arm Cortex-A72 processor in the CPU specific framework.
+
+- Provided better error handling. Platform ports can now define their own error
+  handling, for example to perform platform specific bookkeeping or post-error
+  actions.
+
+- Implemented a unified driver for Arm Cache Coherent Interconnects used for
+  both CCI-400 & CCI-500 IPs. Arm platforms ports have been migrated to this
+  common driver. The standalone CCI-400 driver has been deprecated.
+
+### Issues resolved since last release
+
+- The Trusted Board Boot implementation has been redesigned to provide greater
+  modularity and scalability. See the
+  \{ref}`Authentication Framework & Chain of Trust` document. All missing
+  mandatory features are now implemented.
+- The FVP and Juno ports may now use the hash of the ROTPK stored in the Trusted
+  Key Storage registers to verify the ROTPK. Alternatively, a development public
+  key hash embedded in the BL1 and BL2 binaries might be used instead. The
+  location of the ROTPK is chosen at build-time using the `ARM_ROTPK_LOCATION`
+  build option.
+- GICv3 is now fully supported and stable.
+
+### Known issues
+
+- The version of the AEMv8 Base FVP used in this release resets the model
+  instead of terminating its execution in response to a shutdown request using
+  the PSCI `SYSTEM_OFF` API. This issue will be fixed in a future version of the
+  model.
+- While this version has low on-chip RAM requirements, there are further RAM
+  usage enhancements that could be made.
+- The upstream documentation could be improved for structural consistency,
+  clarity and completeness. In particular, the design documentation is
+  incomplete for PSCI, the TSP(D) and the Juno platform.
+- Building TF-A with compiler optimisations disabled (`-O0`) fails.
+
+## [1.1.0](https://review.trustedfirmware.org/plugins/gitiles/TF-A/trusted-firmware-a/+/refs/tags/v1.0..refs/tags/v1.1) (2015-02-04)
+
+### New features
+
+- A prototype implementation of Trusted Board Boot has been added. Boot loader
+  images are verified by BL1 and BL2 during the cold boot path. BL1 and BL2 use
+  the PolarSSL SSL library to verify certificates and images. The OpenSSL
+  library is used to create the X.509 certificates. Support has been added to
+  `fip_create` tool to package the certificates in a FIP.
+
+- Support for calling CPU and platform specific reset handlers upon entry into
+  BL3-1 during the cold and warm boot paths has been added. This happens after
+  another Boot ROM `reset_handler()` has already run. This enables a developer
+  to perform additional actions or undo actions already performed during the
+  first call of the reset handlers e.g. apply additional errata workarounds.
+
+- Support has been added to demonstrate routing of IRQs to EL3 instead of S-EL1
+  when execution is in secure world.
+
+- The PSCI implementation now conforms to version 1.0 of the PSCI specification.
+  All the mandatory APIs and selected optional APIs are supported. In
+  particular, support for the `PSCI_FEATURES` API has been added. A capability
+  variable is constructed during initialization by examining the `plat_pm_ops`
+  and `spd_pm_ops` exported by the platform and the Secure Payload Dispatcher.
+  This is used by the PSCI FEATURES function to determine which PSCI APIs are
+  supported by the platform.
+
+- Improvements have been made to the PSCI code as follows.
+
+  - The code has been refactored to remove redundant parameters from internal
+    functions.
+  - Changes have been made to the code for PSCI `CPU_SUSPEND`, `CPU_ON` and
+    `CPU_OFF` calls to facilitate an early return to the caller in case a
+    failure condition is detected. For example, a PSCI `CPU_SUSPEND` call
+    returns `SUCCESS` to the caller if a pending interrupt is detected early in
+    the code path.
+  - Optional platform APIs have been added to validate the `power_state` and
+    `entrypoint` parameters early in PSCI `CPU_ON` and `CPU_SUSPEND` code paths.
+  - PSCI migrate APIs have been reworked to invoke the SPD hook to determine the
+    type of Trusted OS and the CPU it is resident on (if applicable). Also,
+    during a PSCI `MIGRATE` call, the SPD hook to migrate the Trusted OS is
+    invoked.
+
+- It is now possible to build TF-A without marking at least an extra page of
+  memory as coherent. The build flag `USE_COHERENT_MEM` can be used to choose
+  between the two implementations. This has been made possible through these
+  changes.
+
+  - An implementation of Bakery locks, where the locks are not allocated in
+    coherent memory has been added.
+  - Memory which was previously marked as coherent is now kept coherent through
+    the use of software cache maintenance operations.
+
+  Approximately, 4K worth of memory is saved for each boot loader stage when
+  `USE_COHERENT_MEM=0`. Enabling this option increases the latencies associated
+  with acquire and release of locks. It also requires changes to the platform
+  ports.
+
+- It is now possible to specify the name of the FIP at build time by defining
+  the `FIP_NAME` variable.
+
+- Issues with dependencies on the 'fiptool' makefile target have been rectified.
+  The `fip_create` tool is now rebuilt whenever its source files change.
+
+- The BL3-1 runtime console is now also used as the crash console. The crash
+  console is changed to SoC UART0 (UART2) from the previous FPGA UART0 (UART0)
+  on Juno. In FVP, it is changed from UART0 to UART1.
+
+- CPU errata workarounds are applied only when the revision and part number
+  match. This behaviour has been made consistent across the debug and release
+  builds. The debug build additionally prints a warning if a mismatch is
+  detected.
+
+- It is now possible to issue cache maintenance operations by set/way for a
+  particular level of data cache. Levels 1-3 are currently supported.
+
+- The following improvements have been made to the FVP port.
+
+  - The build option `FVP_SHARED_DATA_LOCATION` which allowed relocation of
+    shared data into the Trusted DRAM has been deprecated. Shared data is now
+    always located at the base of Trusted SRAM.
+  - BL2 Translation tables have been updated to map only the region of DRAM
+    which is accessible to normal world. This is the region of the 2GB DDR-DRAM
+    memory at 0x80000000 excluding the top 16MB. The top 16MB is accessible to
+    only the secure world.
+  - BL3-2 can now reside in the top 16MB of DRAM which is accessible only to the
+    secure world. This can be done by setting the build flag
+    `FVP_TSP_RAM_LOCATION` to the value `dram`.
+
+- Separate translation tables are created for each boot loader image. The
+  `IMAGE_BLx` build options are used to do this. This allows each stage to
+  create mappings only for areas in the memory map that it needs.
+
+- A Secure Payload Dispatcher (OPTEED) for the OP-TEE Trusted OS has been added.
+  Details of using it with TF-A can be found in {ref}`OP-TEE Dispatcher`
+
+### Issues resolved since last release
+
+- The Juno port has been aligned with the FVP port as follows.
+
+  - Support for reclaiming all BL1 RW memory and BL2 memory by overlaying the
+    BL3-1/BL3-2 NOBITS sections on top of them has been added to the Juno port.
+  - The top 16MB of the 2GB DDR-DRAM memory at 0x80000000 is configured using
+    the TZC-400 controller to be accessible only to the secure world.
+  - The Arm GIC driver is used to configure the GIC-400 instead of using a GIC
+    driver private to the Juno port.
+  - PSCI `CPU_SUSPEND` calls that target a standby state are now supported.
+  - The TZC-400 driver is used to configure the controller instead of direct
+    accesses to the registers.
+
+- The Linux kernel version referred to in the user guide has DVFS and HMP
+  support enabled.
+
+- DS-5 v5.19 did not detect Version 5.8 of the Cortex-A57-A53 Base FVPs in CADI
+  server mode. This issue is not seen with DS-5 v5.20 and Version 6.2 of the
+  Cortex-A57-A53 Base FVPs.
+
+### Known issues
+
+- The Trusted Board Boot implementation is a prototype. There are issues with
+  the modularity and scalability of the design. Support for a Trusted Watchdog,
+  firmware update mechanism, recovery images and Trusted debug is absent. These
+  issues will be addressed in future releases.
+- The FVP and Juno ports do not use the hash of the ROTPK stored in the Trusted
+  Key Storage registers to verify the ROTPK in the `plat_match_rotpk()`
+  function. This prevents the correct establishment of the Chain of Trust at the
+  first step in the Trusted Board Boot process.
+- The version of the AEMv8 Base FVP used in this release resets the model
+  instead of terminating its execution in response to a shutdown request using
+  the PSCI `SYSTEM_OFF` API. This issue will be fixed in a future version of the
+  model.
+- GICv3 support is experimental. There are known issues with GICv3
+  initialization in the TF-A.
+- While this version greatly reduces the on-chip RAM requirements, there are
+  further RAM usage enhancements that could be made.
+- The firmware design documentation for the Test Secure-EL1 Payload (TSP) and
+  its dispatcher (TSPD) is incomplete. Similarly for the PSCI section.
+- The Juno-specific firmware design documentation is incomplete.
+
+## [1.0.0](https://review.trustedfirmware.org/plugins/gitiles/TF-A/trusted-firmware-a/+/refs/tags/v0.4..refs/tags/v1.0) (2014-08-28)
+
+### New features
+
+- It is now possible to map higher physical addresses using non-flat virtual to
+  physical address mappings in the MMU setup.
+
+- Wider use is now made of the per-CPU data cache in BL3-1 to store:
+
+  - Pointers to the non-secure and secure security state contexts.
+  - A pointer to the CPU-specific operations.
+  - A pointer to PSCI specific information (for example the current power
+    state).
+  - A crash reporting buffer.
+
+- The following RAM usage improvements result in a BL3-1 RAM usage reduction
+  from 96KB to 56KB (for FVP with TSPD), and a total RAM usage reduction across
+  all images from 208KB to 88KB, compared to the previous release.
+
+  - Removed the separate `early_exception` vectors from BL3-1 (2KB code size
+    saving).
+  - Removed NSRAM from the FVP memory map, allowing the removal of one (4KB)
+    translation table.
+  - Eliminated the internal `psci_suspend_context` array, saving 2KB.
+  - Correctly dimensioned the PSCI `aff_map_node` array, saving 1.5KB in the FVP
+    port.
+  - Removed calling CPU mpidr from the bakery lock API, saving 160 bytes.
+  - Removed current CPU mpidr from PSCI common code, saving 160 bytes.
+  - Inlined the mmio accessor functions, saving 360 bytes.
+  - Fully reclaimed all BL1 RW memory and BL2 memory on the FVP port by
+    overlaying the BL3-1/BL3-2 NOBITS sections on top of these at runtime.
+  - Made storing the FP register context optional, saving 0.5KB per context (8KB
+    on the FVP port, with TSPD enabled and running on 8 CPUs).
+  - Implemented a leaner `tf_printf()` function, allowing the stack to be
+    greatly reduced.
+  - Removed coherent stacks from the codebase. Stacks allocated in normal memory
+    are now used before and after the MMU is enabled. This saves 768 bytes per
+    CPU in BL3-1.
+  - Reworked the crash reporting in BL3-1 to use less stack.
+  - Optimized the EL3 register state stored in the `cpu_context` structure so
+    that registers that do not change during normal execution are re-initialized
+    each time during cold/warm boot, rather than restored from memory. This
+    saves about 1.2KB.
+  - As a result of some of the above, reduced the runtime stack size in all BL
+    images. For BL3-1, this saves 1KB per CPU.
+
+- PSCI SMC handler improvements to correctly handle calls from secure states and
+  from AArch32.
+
+- CPU contexts are now initialized from the `entry_point_info`. BL3-1 fully
+  determines the exception level to use for the non-trusted firmware (BL3-3)
+  based on the SPSR value provided by the BL2 platform code (or otherwise
+  provided to BL3-1). This allows platform code to directly run non-trusted
+  firmware payloads at either EL2 or EL1 without requiring an EL2 stub or OS
+  loader.
+
+- Code refactoring improvements:
+
+  - Refactored `fvp_config` into a common platform header.
+  - Refactored the fvp gic code to be a generic driver that no longer has an
+    explicit dependency on platform code.
+  - Refactored the CCI-400 driver to not have dependency on platform code.
+  - Simplified the IO driver so it's no longer necessary to call `io_init()` and
+    moved all the IO storage framework code to one place.
+  - Simplified the interface the the TZC-400 driver.
+  - Clarified the platform porting interface to the TSP.
+  - Reworked the TSPD setup code to support the alternate BL3-2 initialization
+    flow where BL3-1 generic code hands control to BL3-2, rather than expecting
+    the TSPD to hand control directly to BL3-2.
+  - Considerable rework to PSCI generic code to support CPU specific operations.
+
+- Improved console log output, by:
+
+  - Adding the concept of debug log levels.
+  - Rationalizing the existing debug messages and adding new ones.
+  - Printing out the version of each BL stage at runtime.
+  - Adding support for printing console output from assembler code, including
+    when a crash occurs before the C runtime is initialized.
+
+- Moved up to the latest versions of the FVPs, toolchain, EDK2, kernel, Linaro
+  file system and DS-5.
+
+- On the FVP port, made the use of the Trusted DRAM region optional at build
+  time (off by default). Normal platforms will not have such a "ready-to-use"
+  DRAM area so it is not a good example to use it.
+
+- Added support for PSCI `SYSTEM_OFF` and `SYSTEM_RESET` APIs.
+
+- Added support for CPU specific reset sequences, power down sequences and
+  register dumping during crash reporting. The CPU specific reset sequences
+  include support for errata workarounds.
+
+- Merged the Juno port into the master branch. Added support for CPU hotplug and
+  CPU idle. Updated the user guide to describe how to build and run on the Juno
+  platform.
+
+### Issues resolved since last release
+
+- Removed the concept of top/bottom image loading. The image loader now
+  automatically detects the position of the image inside the current memory
+  layout and updates the layout to minimize fragmentation. This resolves the
+  image loader limitations of previously releases. There are currently no plans
+  to support dynamic image loading.
+- CPU idle now works on the publicized version of the Foundation FVP.
+- All known issues relating to the compiler version used have now been resolved.
+  This TF-A version uses Linaro toolchain 14.07 (based on GCC 4.9).
+
+### Known issues
+
+- GICv3 support is experimental. The Linux kernel patches to support this are
+  not widely available. There are known issues with GICv3 initialization in the
+  TF-A.
+
+- While this version greatly reduces the on-chip RAM requirements, there are
+  further RAM usage enhancements that could be made.
+
+- The firmware design documentation for the Test Secure-EL1 Payload (TSP) and
+  its dispatcher (TSPD) is incomplete. Similarly for the PSCI section.
+
+- The Juno-specific firmware design documentation is incomplete.
+
+- Some recent enhancements to the FVP port have not yet been translated into the
+  Juno port. These will be tracked via the tf-issues project.
+
+- The Linux kernel version referred to in the user guide has DVFS and HMP
+  support disabled due to some known instabilities at the time of this release.
+  A future kernel version will re-enable these features.
+
+- DS-5 v5.19 does not detect Version 5.8 of the Cortex-A57-A53 Base FVPs in CADI
+  server mode. This is because the `<SimName>` reported by the FVP in this
+  version has changed. For example, for the Cortex-A57x4-A53x4 Base FVP, the
+  `<SimName>` reported by the FVP is `FVP_Base_Cortex_A57x4_A53x4`, while DS-5
+  expects it to be `FVP_Base_A57x4_A53x4`.
+
+  The temporary fix to this problem is to change the name of the FVP in
+  `sw/debugger/configdb/Boards/ARM FVP/Base_A57x4_A53x4/cadi_config.xml`. Change
+  the following line:
+
+  ```
+  <SimName>System Generator:FVP_Base_A57x4_A53x4</SimName>
+  ```
+
+  to System Generator:FVP_Base_Cortex-A57x4_A53x4
+
+  A similar change can be made to the other Cortex-A57-A53 Base FVP variants.
+
+## [0.4.0](https://review.trustedfirmware.org/plugins/gitiles/TF-A/trusted-firmware-a/+/refs/tags/v0.3..refs/tags/v0.4) (2014-06-03)
+
+### New features
+
+- Makefile improvements:
+
+  - Improved dependency checking when building.
+  - Removed `dump` target (build now always produces dump files).
+  - Enabled platform ports to optionally make use of parts of the Trusted
+    Firmware (e.g. BL3-1 only), rather than being forced to use all parts. Also
+    made the `fip` target optional.
+  - Specified the full path to source files and removed use of the `vpath`
+    keyword.
+
+- Provided translation table library code for potential re-use by platforms
+  other than the FVPs.
+
+- Moved architectural timer setup to platform-specific code.
+
+- Added standby state support to PSCI cpu_suspend implementation.
+
+- SRAM usage improvements:
+
+  - Started using the `-ffunction-sections`, `-fdata-sections` and
+    `--gc-sections` compiler/linker options to remove unused code and data from
+    the images. Previously, all common functions were being built into all
+    binary images, whether or not they were actually used.
+  - Placed all assembler functions in their own section to allow more unused
+    functions to be removed from images.
+  - Updated BL1 and BL2 to use a single coherent stack each, rather than one per
+    CPU.
+  - Changed variables that were unnecessarily declared and initialized as
+    non-const (i.e. in the .data section) so they are either uninitialized (zero
+    init) or const.
+
+- Moved the Test Secure-EL1 Payload (BL3-2) to execute in Trusted SRAM by
+  default. The option for it to run in Trusted DRAM remains.
+
+- Implemented a TrustZone Address Space Controller (TZC-400) driver. A default
+  configuration is provided for the Base FVPs. This means the model parameter
+  `-C bp.secure_memory=1` is now supported.
+
+- Started saving the PSCI cpu_suspend 'power_state' parameter prior to
+  suspending a CPU. This allows platforms that implement multiple power-down
+  states at the same affinity level to identify a specific state.
+
+- Refactored the entire codebase to reduce the amount of nesting in header files
+  and to make the use of system/user includes more consistent. Also split
+  platform.h to separate out the platform porting declarations from the required
+  platform porting definitions and the definitions/declarations specific to the
+  platform port.
+
+- Optimized the data cache clean/invalidate operations.
+
+- Improved the BL3-1 unhandled exception handling and reporting. Unhandled
+  exceptions now result in a dump of registers to the console.
+
+- Major rework to the handover interface between BL stages, in particular the
+  interface to BL3-1. The interface now conforms to a specification and is more
+  future proof.
+
+- Added support for optionally making the BL3-1 entrypoint a reset handler
+  (instead of BL1). This allows platforms with an alternative image loading
+  architecture to re-use BL3-1 with fewer modifications to generic code.
+
+- Reserved some DDR DRAM for secure use on FVP platforms to avoid future
+  compatibility problems with non-secure software.
+
+- Added support for secure interrupts targeting the Secure-EL1 Payload (SP)
+  (using GICv2 routing only). Demonstrated this working by adding an interrupt
+  target and supporting test code to the TSP. Also demonstrated non-secure
+  interrupt handling during TSP processing.
+
+### Issues resolved since last release
+
+- Now support use of the model parameter `-C bp.secure_memory=1` in the Base
+  FVPs (see **New features**).
+- Support for secure world interrupt handling now available (see **New
+  features**).
+- Made enough SRAM savings (see **New features**) to enable the Test Secure-EL1
+  Payload (BL3-2) to execute in Trusted SRAM by default.
+- The tested filesystem used for this release (Linaro AArch64 OpenEmbedded
+  14.04) now correctly reports progress in the console.
+- Improved the Makefile structure to make it easier to separate out parts of the
+  TF-A for re-use in platform ports. Also, improved target dependency checking.
+
+### Known issues
+
+- GICv3 support is experimental. The Linux kernel patches to support this are
+  not widely available. There are known issues with GICv3 initialization in the
+  TF-A.
+- Dynamic image loading is not available yet. The current image loader
+  implementation (used to load BL2 and all subsequent images) has some
+  limitations. Changing BL2 or BL3-1 load addresses in certain ways can lead to
+  loading errors, even if the images should theoretically fit in memory.
+- TF-A still uses too much on-chip Trusted SRAM. A number of RAM usage
+  enhancements have been identified to rectify this situation.
+- CPU idle does not work on the advertised version of the Foundation FVP. Some
+  FVP fixes are required that are not available externally at the time of
+  writing. This can be worked around by disabling CPU idle in the Linux kernel.
+- Various bugs in TF-A, UEFI and the Linux kernel have been observed when using
+  Linaro toolchain versions later than 13.11. Although most of these have been
+  fixed, some remain at the time of writing. These mainly seem to relate to a
+  subtle change in the way the compiler converts between 64-bit and 32-bit
+  values (e.g. during casting operations), which reveals previously hidden bugs
+  in client code.
+- The firmware design documentation for the Test Secure-EL1 Payload (TSP) and
+  its dispatcher (TSPD) is incomplete. Similarly for the PSCI section.
+
+## [0.3.0](https://review.trustedfirmware.org/plugins/gitiles/TF-A/trusted-firmware-a/+/refs/tags/v0.2..refs/tags/v0.3) (2014-02-28)
+
+### New features
+
+- Support for Foundation FVP Version 2.0 added. The documented UEFI
+  configuration disables some devices that are unavailable in the Foundation
+  FVP, including MMC and CLCD. The resultant UEFI binary can be used on the
+  AEMv8 and Cortex-A57-A53 Base FVPs, as well as the Foundation FVP.
+
+  \:::\{note} The software will not work on Version 1.0 of the Foundation FVP.
+  \:::
+
+- Enabled third party contributions. Added a new contributing.md containing
+  instructions for how to contribute and updated copyright text in all files to
+  acknowledge contributors.
+
+- The PSCI CPU_SUSPEND API has been stabilised to the extent where it can be
+  used for entry into power down states with the following restrictions:
+
+  - Entry into standby states is not supported.
+  - The API is only supported on the AEMv8 and Cortex-A57-A53 Base FVPs.
+
+- The PSCI AFFINITY_INFO api has undergone limited testing on the Base FVPs to
+  allow experimental use.
+
+- Required C library and runtime header files are now included locally in TF-A
+  instead of depending on the toolchain standard include paths. The local
+  implementation has been cleaned up and reduced in scope.
+
+- Added I/O abstraction framework, primarily to allow generic code to load
+  images in a platform-independent way. The existing image loading code has been
+  reworked to use the new framework. Semi-hosting and NOR flash I/O drivers are
+  provided.
+
+- Introduced Firmware Image Package (FIP) handling code and tools. A FIP
+  combines multiple firmware images with a Table of Contents (ToC) into a single
+  binary image. The new FIP driver is another type of I/O driver. The Makefile
+  builds a FIP by default and the FVP platform code expect to load a FIP from
+  NOR flash, although some support for image loading using semi- hosting is
+  retained.
+
+  \:::\{note} Building a FIP by default is a non-backwards-compatible change. :::
+
+  \:::\{note} Generic BL2 code now loads a BL3-3 (non-trusted firmware) image
+  into DRAM instead of expecting this to be pre-loaded at known location. This
+  is also a non-backwards-compatible change. :::
+
+  \:::\{note} Some non-trusted firmware (e.g. UEFI) will need to be rebuilt so
+  that it knows the new location to execute from and no longer needs to copy
+  particular code modules to DRAM itself. :::
+
+- Reworked BL2 to BL3-1 handover interface. A new composite structure
+  (bl31_args) holds the superset of information that needs to be passed from BL2
+  to BL3-1, including information on how handover execution control to BL3-2 (if
+  present) and BL3-3 (non-trusted firmware).
+
+- Added library support for CPU context management, allowing the saving and
+  restoring of
+
+  - Shared system registers between Secure-EL1 and EL1.
+  - VFP registers.
+  - Essential EL3 system registers.
+
+- Added a framework for implementing EL3 runtime services. Reworked the PSCI
+  implementation to be one such runtime service.
+
+- Reworked the exception handling logic, making use of both SP_EL0 and SP_EL3
+  stack pointers for determining the type of exception, managing general purpose
+  and system register context on exception entry/exit, and handling SMCs. SMCs
+  are directed to the correct EL3 runtime service.
+
+- Added support for a Test Secure-EL1 Payload (TSP) and a corresponding
+  Dispatcher (TSPD), which is loaded as an EL3 runtime service. The TSPD
+  implements Secure Monitor functionality such as world switching and EL1
+  context management, and is responsible for communication with the TSP.
+
+  \:::\{note} The TSPD does not yet contain support for secure world interrupts.
+  \:::
+
+  \:::\{note} The TSP/TSPD is not built by default. :::
+
+### Issues resolved since last release
+
+- Support has been added for switching context between secure and normal worlds
+  in EL3.
+- PSCI API calls `AFFINITY_INFO` & `PSCI_VERSION` have now been tested (to a
+  limited extent).
+- The TF-A build artifacts are now placed in the `./build` directory and
+  sub-directories instead of being placed in the root of the project.
+- TF-A is now free from build warnings. Build warnings are now treated as
+  errors.
+- TF-A now provides C library support locally within the project to maintain
+  compatibility between toolchains/systems.
+- The PSCI locking code has been reworked so it no longer takes locks in an
+  incorrect sequence.
+- The RAM-disk method of loading a Linux file-system has been confirmed to work
+  with the TF-A and Linux kernel version (based on version 3.13) used in this
+  release, for both Foundation and Base FVPs.
+
+### Known issues
+
+The following is a list of issues which are expected to be fixed in the future
+releases of TF-A.
+
+- The TrustZone Address Space Controller (TZC-400) is not being programmed yet.
+  Use of model parameter `-C bp.secure_memory=1` is not supported.
+- No support yet for secure world interrupt handling.
+- GICv3 support is experimental. The Linux kernel patches to support this are
+  not widely available. There are known issues with GICv3 initialization in
+  TF-A.
+- Dynamic image loading is not available yet. The current image loader
+  implementation (used to load BL2 and all subsequent images) has some
+  limitations. Changing BL2 or BL3-1 load addresses in certain ways can lead to
+  loading errors, even if the images should theoretically fit in memory.
+- TF-A uses too much on-chip Trusted SRAM. Currently the Test Secure-EL1 Payload
+  (BL3-2) executes in Trusted DRAM since there is not enough SRAM. A number of
+  RAM usage enhancements have been identified to rectify this situation.
+- CPU idle does not work on the advertised version of the Foundation FVP. Some
+  FVP fixes are required that are not available externally at the time of
+  writing.
+- Various bugs in TF-A, UEFI and the Linux kernel have been observed when using
+  Linaro toolchain versions later than 13.11. Although most of these have been
+  fixed, some remain at the time of writing. These mainly seem to relate to a
+  subtle change in the way the compiler converts between 64-bit and 32-bit
+  values (e.g. during casting operations), which reveals previously hidden bugs
+  in client code.
+- The tested filesystem used for this release (Linaro AArch64 OpenEmbedded
+  14.01) does not report progress correctly in the console. It only seems to
+  produce error output, not standard output. It otherwise appears to function
+  correctly. Other filesystem versions on the same software stack do not exhibit
+  the problem.
+- The Makefile structure doesn't make it easy to separate out parts of the TF-A
+  for re-use in platform ports, for example if only BL3-1 is required in a
+  platform port. Also, dependency checking in the Makefile is flawed.
+- The firmware design documentation for the Test Secure-EL1 Payload (TSP) and
+  its dispatcher (TSPD) is incomplete. Similarly for the PSCI section.
+
+## [0.2.0](https://review.trustedfirmware.org/plugins/gitiles/TF-A/trusted-firmware-a/+/4b825dc642cb6eb9a060e54bf8d69288fbee4904..refs/tags/v0.2) (2013-10-25)
+
+### New features
+
+- First source release.
+- Code for the PSCI suspend feature is supplied, although this is not enabled by
+  default since there are known issues (see below).
+
+### Issues resolved since last release
+
+- The "psci" nodes in the FDTs provided in this release now fully comply with
+  the recommendations made in the PSCI specification.
+
+### Known issues
+
+The following is a list of issues which are expected to be fixed in the future
+releases of TF-A.
+
+- The TrustZone Address Space Controller (TZC-400) is not being programmed yet.
+  Use of model parameter `-C bp.secure_memory=1` is not supported.
+- No support yet for secure world interrupt handling or for switching context
+  between secure and normal worlds in EL3.
+- GICv3 support is experimental. The Linux kernel patches to support this are
+  not widely available. There are known issues with GICv3 initialization in
+  TF-A.
+- Dynamic image loading is not available yet. The current image loader
+  implementation (used to load BL2 and all subsequent images) has some
+  limitations. Changing BL2 or BL3-1 load addresses in certain ways can lead to
+  loading errors, even if the images should theoretically fit in memory.
+- Although support for PSCI `CPU_SUSPEND` is present, it is not yet stable and
+  ready for use.
+- PSCI API calls `AFFINITY_INFO` & `PSCI_VERSION` are implemented but have not
+  been tested.
+- The TF-A make files result in all build artifacts being placed in the root of
+  the project. These should be placed in appropriate sub-directories.
+- The compilation of TF-A is not free from compilation warnings. Some of these
+  warnings have not been investigated yet so they could mask real bugs.
+- TF-A currently uses toolchain/system include files like stdio.h. It should
+  provide versions of these within the project to maintain compatibility between
+  toolchains/systems.
+- The PSCI code takes some locks in an incorrect sequence. This may cause
+  problems with suspend and hotplug in certain conditions.
+- The Linux kernel used in this release is based on version 3.12-rc4. Using this
+  kernel with the TF-A fails to start the file-system as a RAM-disk. It fails to
+  execute user-space `init` from the RAM-disk. As an alternative, the
+  VirtioBlock mechanism can be used to provide a file-system to the kernel.

+Activity Monitors
+=================
+
+FEAT_AMUv1 of the Armv8-A architecture introduces the Activity Monitors
+extension. This extension describes the architecture for the Activity Monitor
+Unit (|AMU|), an optional non-invasive component for monitoring core events
+through a set of 64-bit counters.
+
+When the ``ENABLE_AMU=1`` build option is provided, Trusted Firmware-A sets up
+the |AMU| prior to its exit from EL3, and will save and restore architected
+|AMU| counters as necessary upon suspend and resume.
+
+.. _Activity Monitor Auxiliary Counters:
+
+Auxiliary counters
+------------------
+
+FEAT_AMUv1 describes a set of implementation-defined auxiliary counters (also
+known as group 1 counters), controlled by the ``ENABLE_AMU_AUXILIARY_COUNTERS``
+build option.
+
+As a security precaution, Trusted Firmware-A does not enable these by default.
+Instead, platforms may configure their auxiliary counters through one of two
+possible mechanisms:
+
+- |FCONF|, controlled by the ``ENABLE_AMU_FCONF`` build option.
+- A platform implementation of the ``plat_amu_topology`` function (the default).
+
+See :ref:`Activity Monitor Unit (AMU) Bindings` for documentation on the |FCONF|
+device tree bindings.

+Arm SiP Services
+================
+
+This document enumerates and describes the Arm SiP (Silicon Provider) services.
+
+SiP services are non-standard, platform-specific services offered by the silicon
+implementer or platform provider. They are accessed via ``SMC`` ("SMC calls")
+instruction executed from Exception Levels below EL3. SMC calls for SiP
+services:
+
+-  Follow `SMC Calling Convention`_;
+-  Use SMC function IDs that fall in the SiP range, which are ``0xc2000000`` -
+   ``0xc200ffff`` for 64-bit calls, and ``0x82000000`` - ``0x8200ffff`` for 32-bit
+   calls.
+
+The Arm SiP implementation offers the following services:
+
+-  Performance Measurement Framework (PMF)
+-  Execution State Switching service
+-  DebugFS interface
+
+Source definitions for Arm SiP service are located in the ``arm_sip_svc.h`` header
+file.
+
+Performance Measurement Framework (PMF)
+---------------------------------------
+
+The :ref:`Performance Measurement Framework <firmware_design_pmf>`
+allows callers to retrieve timestamps captured at various paths in TF-A
+execution.
+
+Execution State Switching service
+---------------------------------
+
+Execution State Switching service provides a mechanism for a non-secure lower
+Exception Level (either EL2, or NS EL1 if EL2 isn't implemented) to request to
+switch its execution state (a.k.a. Register Width), either from AArch64 to
+AArch32, or from AArch32 to AArch64, for the calling CPU. This service is only
+available when Trusted Firmware-A (TF-A) is built for AArch64 (i.e. when build
+option ``ARCH`` is set to ``aarch64``).
+
+``ARM_SIP_SVC_EXE_STATE_SWITCH``
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Arguments:
+        uint32_t Function ID
+        uint32_t PC hi
+        uint32_t PC lo
+        uint32_t Cookie hi
+        uint32_t Cookie lo
+
+    Return:
+        uint32_t
+
+The function ID parameter must be ``0x82000020``. It uniquely identifies the
+Execution State Switching service being requested.
+
+The parameters *PC hi* and *PC lo* defines upper and lower words, respectively,
+of the entry point (physical address) at which execution should start, after
+Execution State has been switched. When calling from AArch64, *PC hi* must be 0.
+
+When execution starts at the supplied entry point after Execution State has been
+switched, the parameters *Cookie hi* and *Cookie lo* are passed in CPU registers
+0 and 1, respectively. When calling from AArch64, *Cookie hi* must be 0.
+
+This call can only be made on the primary CPU, before any secondaries were
+brought up with ``CPU_ON`` PSCI call. Otherwise, the call will always fail.
+
+The effect of switching execution state is as if the Exception Level were
+entered for the first time, following power on. This means CPU registers that
+have a defined reset value by the Architecture will assume that value. Other
+registers should not be expected to hold their values before the call was made.
+CPU endianness, however, is preserved from the previous execution state. Note
+that this switches the execution state of the calling CPU only. This is not a
+substitute for PSCI ``SYSTEM_RESET``.
+
+The service may return the following error codes:
+
+-  ``STATE_SW_E_PARAM``: If any of the parameters were deemed invalid for
+   a specific request.
+-  ``STATE_SW_E_DENIED``: If the call is not successful, or when TF-A is
+   built for AArch32.
+
+If the call is successful, the caller wouldn't observe the SMC returning.
+Instead, execution starts at the supplied entry point, with the CPU registers 0
+and 1 populated with the supplied *Cookie hi* and *Cookie lo* values,
+respectively.
+
+DebugFS interface
+-----------------
+
+The optional DebugFS interface is accessed through an SMC SiP service. Refer
+to the component documentation for details.
+
+String parameters are passed through a shared buffer using a specific union:
+
+.. code:: c
+
+    union debugfs_parms {
+        struct {
+            char fname[MAX_PATH_LEN];
+        } open;
+
+        struct mount {
+            char srv[MAX_PATH_LEN];
+            char where[MAX_PATH_LEN];
+            char spec[MAX_PATH_LEN];
+        } mount;
+
+        struct {
+            char path[MAX_PATH_LEN];
+            dir_t dir;
+        } stat;
+
+        struct {
+            char oldpath[MAX_PATH_LEN];
+            char newpath[MAX_PATH_LEN];
+        } bind;
+    };
+
+Format of the dir_t structure as such:
+
+.. code:: c
+
+    typedef struct {
+        char		name[NAMELEN];
+        long		length;
+        unsigned char	mode;
+        unsigned char	index;
+        unsigned char	dev;
+        qid_t		qid;
+    } dir_t;

+========
+Debug FS
+========
+
+.. contents::
+
+Overview
+--------
+
+The *DebugFS* feature is primarily aimed at exposing firmware debug data to
+higher SW layers such as a non-secure component. Such component can be the
+TFTF test payload or a Linux kernel module.
+
+Virtual filesystem
+------------------
+
+The core functionality lies in a virtual file system based on a 9p file server
+interface (`Notes on the Plan 9 Kernel Source`_ and
+`Linux 9p remote filesystem protocol`_).
+The implementation permits exposing virtual files, firmware drivers, and file blobs.
+
+Namespace
+~~~~~~~~~
+
+Two namespaces are exposed:
+
+  - # is used as root for drivers (e.g. #t0 is the first uart)
+  - / is used as root for virtual "files" (e.g. /fip, or /dev/uart)
+
+9p interface
+~~~~~~~~~~~~
+
+The associated primitives are:
+
+- Unix-like:
+
+  - open(): create a file descriptor that acts as a handle to the file passed as
+    an argument.
+  - close(): close the file descriptor created by open().
+  - read(): read from a file to a buffer.
+  - write(): write from a buffer to a file.
+  - seek(): set the file position indicator of a file descriptor either to a
+    relative or an absolute offset.
+  - stat(): get information about a file (type, mode, size, ...).
+
+.. code:: c
+
+    int open(const char *name, int flags);
+    int close(int fd);
+    int read(int fd, void *buf, int n);
+    int write(int fd, void *buf, int n);
+    int seek(int fd, long off, int whence);
+    int stat(char *path, dir_t *dir);
+
+- Specific primitives :
+
+  - mount(): create a link between a driver and spec.
+  - create(): create a file in a specific location.
+  - bind(): expose the content of a directory to another directory.
+
+.. code:: c
+
+    int mount(char *srv, char *mnt, char *spec);
+    int create(const char *name, int flags);
+    int bind(char *path, char *where);
+
+This interface is embedded into the BL31 run-time payload when selected by build
+options. The interface multiplexes drivers or emulated "files":
+
+- Debug data can be partitioned into different virtual files e.g. expose PMF
+  measurements through a file, and internal firmware state counters through
+  another file.
+- This permits direct access to a firmware driver, mainly for test purposes
+  (e.g. a hardware device that may not be accessible to non-privileged/
+  non-secure layers, or for which no support exists in the NS side).
+
+SMC interface
+-------------
+
+The communication with the 9p layer in BL31 is made through an SMC conduit
+(`SMC Calling Convention`_), using a specific SiP Function Id. An NS
+shared buffer is used to pass path string parameters, or e.g. to exchange
+data on a read operation. Refer to :ref:`ARM SiP Services <arm sip services>`
+for a description of the SMC interface.
+
+Security considerations
+-----------------------
+
+- Due to the nature of the exposed data, the feature is considered experimental
+  and importantly **shall only be used in debug builds**.
+- Several primitive imply string manipulations and usage of string formats.
+- Special care is taken with the shared buffer to avoid TOCTOU attacks.
+
+Limitations
+-----------
+
+- In order to setup the shared buffer, the component consuming the interface
+  needs to allocate a physical page frame and transmit its address.
+- In order to map the shared buffer, BL31 requires enabling the dynamic xlat
+  table option.
+- Data exchange is limited by the shared buffer length. A large read operation
+  might be split into multiple read operations of smaller chunks.
+- On concurrent access, a spinlock is implemented in the BL31 service to protect
+  the internal work buffer, and re-entrancy into the filesystem layers.
+- Notice, a physical device driver if exposed by the firmware may conflict with
+  the higher level OS if the latter implements its own driver for the same
+  physical device.
+
+Applications
+------------
+
+The SMC interface is accessible from an NS environment, that is:
+
+- a test payload, bootloader or hypervisor running at NS-EL2
+- a Linux kernel driver running at NS-EL1
+- a Linux userspace application through the kernel driver

+EL3 Secure Partition Manager
+****************************
+
+.. contents::
+
+Foreword
+========
+
+This document describes the design of the EL3 SPMC based on the FF-A specification.
+EL3 SPMC provides reference FF-A compliant implementation without S-EL2 virtualization support,
+to help adopt and migrate to FF-A early.
+EL3 SPMC implementation in TF-A:
+
+- Manages a single S-EL1 Secure Partition
+- Provides a standard protocol for communication and memory sharing between FF-A endpoints.
+- Provides support for EL3 Logical Partitions to support easy migration from EL3 to S-EL1.
+
+Sample reference stack
+======================
+
+The following diagram illustrates a possible configuration when the
+FEAT_SEL2 architecture extension is not implemented, showing the SPMD
+and SPMC at EL3, one S-EL1 secure partition, with an optional
+Hypervisor:
+
+.. image:: ../resources/diagrams/ff-a-spm-at-el3.png
+
+TF-A build options
+==================
+
+This section explains the TF-A build options involved in building
+an FF-A based SPM where the SPMD and SPMC are located at EL3:
+
+- **SPD=spmd**: this option selects the SPMD component to relay the FF-A
+  protocol from NWd to SWd back and forth. It is not possible to
+  enable another Secure Payload Dispatcher when this option is chosen.
+- **SPMC_AT_EL3**: this option adjusts the SPMC exception level to being
+  at EL3.
+- **ARM_SPMC_MANIFEST_DTS**: this option specifies a manifest file
+  providing SP description. It is required when
+  ``SPMC_AT_EL3`` is enabled, the secure partitions are loaded
+  by BL2 on behalf of the SPMC.
+
+Notes:
+
+- BL32 option is re-purposed to specify the S-EL1 TEE or SP image.
+  BL32 option can be omitted if using TF-A Test Secure Payload as SP.
+- BL33 option can specify the TFTF binary or a normal world loader
+  such as U-Boot or the UEFI framework payload.
+
+Sample TF-A build command line when the SPMC is located at EL3:
+
+.. code:: shell
+
+    make \
+    CROSS_COMPILE=aarch64-none-elf- \
+    SPD=spmd \
+    SPMD_SPM_AT_SEL2=0 \
+    SPMC_AT_EL3=1 \
+    BL32=<path-to-tee-binary> (opt for TSP) \
+    BL33=<path-to-bl33-binary> \
+    PLAT=fvp \
+    all fip
+
+FVP model invocation
+====================
+
+Sample FVP command line invocation:
+
+.. code:: shell
+
+    <path-to-fvp-model>/FVP_Base_RevC-2xAEMvA -C pctl.startup=0.0.0.0 \
+    -C cluster0.NUM_CORES=4 -C cluster1.NUM_CORES=4 -C bp.secure_memory=1 \
+    -C bp.secureflashloader.fname=trusted-firmware-a/build/fvp/debug/bl1.bin \
+    -C bp.flashloader0.fname=trusted-firmware-a/build/fvp/debug/fip.bin \
+    -C bp.pl011_uart0.out_file=fvp-uart0.log -C bp.pl011_uart1.out_file=fvp-uart1.log \
+    -C bp.pl011_uart2.out_file=fvp-uart2.log -C bp.vis.disable_visualisation=1
+
+
+Platform Guide
+==============
+
+- Platform Hooks  See - `[4]`_
+
+  - plat_spmc_shmem_begin
+  - plat_spmc_shmem_reclaim
+
+SPMC provides platform hooks related to memory management interfaces.
+These hooks can be used for platform specific implementations like
+for managing access control, programming TZ Controller or MPUs.
+These hooks are called by SPMC before the initial share request completes,
+and after the final reclaim has been completed.
+
+- Datastore
+
+  - plat_spmc_shmem_datastore_get
+
+    EL3 SPMC uses datastore for tracking memory transaction descriptors.
+    On FVP platform datastore is allocated from TZC DRAM section.
+    Other platforms need to allocate a similar secure memory region
+    to be used as shared memory datastore.
+
+    The accessor function is used during SPMC initialization to obtain
+    address and size of the datastore.
+    SPMC will also zero out the provided memory region.
+
+- Platform Defines See - `[5]`_
+
+  - SECURE_PARTITION_COUNT
+    Number of Secure Partitions supported: must be 1.
+
+  - NS_PARTITION_COUNT
+    Number of NWd Partitions supported.
+
+  - MAX_EL3_LP_DESCS_COUNT
+    Number of Logical Partitions supported.
+
+Logical Secure Partition (LSP)
+==============================
+
+- The SPMC provides support for statically allocated EL3 Logical Secure Partitions
+  as per FF-A v1.1 specification.
+- The DECLARE_LOGICAL_PARTITION macro can be used to add a LSP.
+- For reference implementation See - `[2]`_
+
+.. image:: ../resources/diagrams/ff-a-lsp-at-el3.png
+
+SPMC boot
+=========
+
+The SPMD and SPMC are built into the BL31 image along with TF-A's runtime components.
+BL2 loads the BL31 image as a part of (secure) boot process.
+
+The SPMC manifest is loaded by BL2 as the ``TOS_FW_CONFIG`` image `[9]`_.
+
+BL2 passes the SPMC manifest address to BL31 through a register.
+
+At boot time, the SPMD in BL31 runs from the primary core, initializes the core
+contexts and launches the SPMC passing the following information through
+registers:
+
+- X0 holds the SPMC manifest blob address.
+- X4 holds the currently running core linear id.
+
+Parsing SP partition manifests
+------------------------------
+
+SPMC consumes the SP manifest, as defined in `[7]`_.
+SP manifest fields align with Hafnium SP manifest for easy porting.
+
+.. code:: shell
+
+	compatible = "arm,ffa-manifest-1.0";
+
+	ffa-version = <0x00010001>; /* 31:16 - Major, 15:0 - Minor */
+	id = <0x8001>;
+	uuid = <0x6b43b460 0x74a24b78 0xade24502 0x40682886>;
+	messaging-method = <0x3>; /* Direct Messaging Only */
+	exception-level = <0x2>;  /* S-EL1 */
+	execution-state = <0>;
+	execution-ctx-count = <8>;
+	gp-register-num = <0>;
+	power-management-messages = <0x7>;
+
+
+Passing boot data to the SP
+---------------------------
+
+In `[1]`_ , the section  "Boot information protocol" defines a method for passing
+data to the SPs at boot time. It specifies the format for the boot information
+descriptor and boot information header structures, which describe the data to be
+exchanged between SPMC and SP.
+The specification also defines the types of data that can be passed.
+The aggregate of both the boot info structures and the data itself is designated
+the boot information blob, and is passed to a Partition as a contiguous memory
+region.
+
+Currently, the SPM implementation supports the FDT type which is used to pass the
+partition's DTB manifest.
+
+The region for the boot information blob is statically allocated (4K) by SPMC.
+BLOB contains Boot Info Header, followed by SP Manifest contents.
+
+The configuration of the boot protocol is done in the SP manifest. As defined by
+the specification, the manifest field 'gp-register-num' configures the GP register
+which shall be used to pass the address to the partitions boot information blob when
+booting the partition.
+
+Supported interfaces
+====================
+
+The following interfaces are exposed to SPs only:
+
+-  ``FFA_MSG_WAIT``
+-  ``FFA_MEM_RETRIEVE_REQ``
+-  ``FFA_MEM_RETRIEVE_RESP``
+-  ``FFA_MEM_RELINQUISH``
+-  ``FFA_SECONDARY_EP_REGISTER``
+
+The following interfaces are exposed to both NS Client and SPs:
+
+-  ``FFA_VERSION``
+-  ``FFA_FEATURES``
+-  ``FFA_RX_RELEASE``
+-  ``FFA_RXTX_MAP``
+-  ``FFA_RXTX_UNMAP``
+-  ``FFA_PARTITION_INFO_GET``
+-  ``FFA_ID_GET``
+-  ``FFA_MSG_SEND_DIRECT_REQ``
+-  ``FFA_MSG_SEND_DIRECT_RESP``
+-  ``FFA_MEM_FRAG_TX``
+-  ``FFA_SPM_ID_GET``
+
+The following additional interfaces are forwarded from SPMD to support NS Client:
+
+-  ``FFA_RUN``
+-  ``FFA_MEM_LEND``
+-  ``FFA_MEM_SHARE``
+-  ``FFA_MEM_FRAG_RX``
+-  ``FFA_MEM_RECLAIM``
+
+
+FFA_VERSION
+-----------
+
+``FFA_VERSION`` requires a *requested_version* parameter from the caller.
+SPMD forwards call to SPMC, the SPMC returns its own implemented version.
+SPMC asserts SP and SPMC are at same FF-A Version.
+
+FFA_FEATURES
+------------
+
+FF-A features supported by the SPMC may be discovered by secure partitions at
+boot (that is prior to NWd is booted) or run-time.
+
+The SPMC calling FFA_FEATURES at secure physical FF-A instance always get
+FFA_SUCCESS from the SPMD.
+
+The request made by an Hypervisor or OS kernel is forwarded to the SPMC and
+the response relayed back to the NWd.
+
+
+FFA_RXTX_MAP
+------------
+
+FFA_RXTX_UNMAP
+--------------
+
+When invoked from a secure partition FFA_RXTX_MAP maps the provided send and
+receive buffers described by their PAs to the EL3 translation regime
+as secure buffers in the MMU descriptors.
+
+When invoked from the Hypervisor or OS kernel, the buffers are mapped into the
+SPMC EL3 translation regime and marked as NS buffers in the MMU
+descriptors.
+
+The FFA_RXTX_UNMAP unmaps the RX/TX pair from the translation regime of the
+caller, either it being the Hypervisor or OS kernel, as well as a secure
+partition.
+
+FFA_PARTITION_INFO_GET
+----------------------
+
+Partition info get call can originate:
+
+- from SP to SPMC
+- from Hypervisor or OS kernel to SPMC. The request is relayed by the SPMD.
+
+The format (v1.0 or v1.1) of the populated data structure returned is based upon the
+FFA version of the calling entity.
+
+EL3 SPMC also supports returning only the count of partitions deployed.
+
+All LSPs and SP are discoverable from FFA_PARTITION_INFO_GET call made by
+either SP or NWd entities.
+
+FFA_ID_GET
+----------
+
+The FF-A ID space is split into a non-secure space and secure space:
+
+- FF-A ID with bit 15 clear relates to VMs.
+- FF-A ID with bit 15 set related to SPs or LSPs.
+- FF-A IDs 0, 0xffff, 0x8000 are assigned respectively to the Hypervisor
+  (or OS Kernel if Hyp is absent), SPMD and SPMC.
+
+This convention helps the SPM to determine the origin and destination worlds in
+an FF-A ABI invocation. In particular the SPM shall filter unauthorized
+transactions in its world switch routine. It must not be permitted for a VM to
+use a secure FF-A ID as origin world by spoofing:
+
+- A VM-to-SP direct request/response shall set the origin world to be non-secure
+  (FF-A ID bit 15 clear) and destination world to be secure (FF-A ID bit 15
+  set).
+- Similarly, an SP-to-LSP direct request/response shall set the FF-A ID bit 15
+  for both origin and destination IDs.
+
+An incoming direct message request arriving at SPMD from NWd is forwarded to
+SPMC without a specific check. The SPMC is resumed through eret and "knows" the
+message is coming from normal world in this specific code path. Thus the origin
+endpoint ID must be checked by SPMC for being a normal world ID.
+
+An SP sending a direct message request must have bit 15 set in its origin
+endpoint ID and this can be checked by the SPMC when the SP invokes the ABI.
+
+The SPMC shall reject the direct message if the claimed world in origin endpoint
+ID is not consistent:
+
+-  It is either forwarded by SPMD and thus origin endpoint ID must be a "normal
+   world ID",
+-  or initiated by an SP and thus origin endpoint ID must be a "secure world ID".
+
+
+FFA_MSG_SEND_DIRECT_REQ
+-----------------------
+
+FFA_MSG_SEND_DIRECT_RESP
+------------------------
+
+This is a mandatory interface for secure partitions participating in direct request
+and responses with the following rules:
+
+- An SP can send a direct request to LSP.
+- An LSP can send a direct response to SP.
+- An SP cannot send a direct request to an Hypervisor or OS kernel.
+- An Hypervisor or OS kernel can send a direct request to an SP or LSP.
+- An SP and LSP can send a direct response to an Hypervisor or OS kernel.
+- SPMD can send direct request to SPMC.
+
+FFA_SPM_ID_GET
+--------------
+
+Returns the FF-A ID allocated to an SPM component which can be one of SPMD
+or SPMC.
+
+At initialization, the SPMC queries the SPMD for the SPMC ID, using the
+FFA_ID_GET interface, and records it. The SPMC can also query the SPMD ID using
+the FFA_SPM_ID_GET interface at the secure physical FF-A instance.
+
+Secure partitions call this interface at the virtual FF-A instance, to which
+the SPMC returns the SPMC ID.
+
+The Hypervisor or OS kernel can issue the FFA_SPM_ID_GET call handled by the
+SPMD, which returns the SPMC ID.
+
+FFA_ID_GET
+----------
+
+Returns the FF-A ID of the calling endpoint.
+
+FFA_MEM_SHARE
+-------------
+
+FFA_MEM_LEND
+------------
+
+- If SP is borrower in the memory transaction, these calls are forwarded to SPMC.
+  SPMC performs Relayer responsibilities, caches the memory descriptors in the datastore,
+  and allocates FF-A memory handle.
+- If format of descriptor was v1.0, SPMC converts the descriptor to v1.1 before caching.
+  In case of fragmented sharing, conversion of memory descriptors happens after last
+  fragment has been received.
+- Multiple borrowers (including NWd endpoint) and fragmented memory sharing are supported.
+
+FFA_MEM_RETRIEVE_REQ
+--------------------
+
+FFA_MEM_RETRIEVE_RESP
+---------------------
+
+- Memory retrieve is supported only from SP.
+- SPMC fetches the cached memory descriptor from the datastore,
+- Performs Relayer responsiilities and sends FFA_MEM_RETRIEVE_RESP back to SP.
+- If descriptor size is more than RX buffer size, SPMC will send the descriptor in fragments.
+- SPMC will set NS Bit to 1 in memory descriptor response.
+
+FFA_MEM_FRAG_RX
+---------------
+
+FFA_MEM_FRAG_TX
+---------------
+
+FFA_MEM_FRAG_RX is to be used by:
+
+- SP if FFA_MEM_RETRIEVE_RESP returned descriptor with fragment length less than total length.
+- or by SPMC if FFA_MEM_SHARE/FFA_MEM_LEND is called with fragment length less than total length.
+
+SPMC validates handle and Endpoint ID and returns response with FFA_MEM_FRAG_TX.
+
+FFA_SECONDARY_EP_REGISTER
+-------------------------
+
+When the SPMC boots, secure partition is initialized on its primary
+Execution Context.
+
+The FFA_SECONDARY_EP_REGISTER interface is to be used by a secure partition
+from its first execution context, to provide the entry point address for
+secondary execution contexts.
+
+A secondary EC is first resumed either upon invocation of PSCI_CPU_ON from
+the NWd or by invocation of FFA_RUN.
+
+Power management
+================
+
+In platforms with or without secure virtualization:
+
+- The NWd owns the platform PM policy.
+- The Hypervisor or OS kernel is the component initiating PSCI service calls.
+- The EL3 PSCI library is in charge of the PM coordination and control
+  (eventually writing to platform registers).
+- While coordinating PM events, the PSCI library calls backs into the Secure
+  Payload Dispatcher for events the latter has statically registered to.
+
+When using the SPMD as a Secure Payload Dispatcher:
+
+- A power management event is relayed through the SPD hook to the SPMC.
+- In the current implementation CPU_ON (svc_on_finish), CPU_OFF
+  (svc_off), CPU_SUSPEND (svc_suspend) and CPU_SUSPEND_RESUME (svc_suspend_finish)
+  hooks are registered.
+
+Secure partitions scheduling
+============================
+
+The FF-A specification `[1]`_ provides two ways to relinquinsh CPU time to
+secure partitions. For this a VM (Hypervisor or OS kernel), or SP invokes one of:
+
+- the FFA_MSG_SEND_DIRECT_REQ interface.
+- the FFA_RUN interface.
+
+Additionally a secure interrupt can pre-empt the normal world execution and give
+CPU cycles by transitioning to EL3.
+
+Partition Runtime State and Model
+=================================
+
+EL3 SPMC implements Partition runtime states are described in v1.1 FF-A specification `[1]`_
+
+An SP can be in one of the following state:
+
+- RT_STATE_WAITING
+- RT_STATE_RUNNING
+- RT_STATE_PREEMPTED
+- RT_STATE_BLOCKED
+
+An SP will transition to one of the following runtime model when not in waiting state:
+
+- RT_MODEL_DIR_REQ
+- RT_MODEL_RUN
+- RT_MODEL_INIT
+- RT_MODEL_INTR
+
+Platform topology
+=================
+
+SPMC only supports a single Pinned MP S-EL1 SP. The *execution-ctx-count*
+SP manifest field should match the number of physical PE.
+
+Interrupt handling
+==================
+
+Secure Interrupt handling
+-------------------------
+
+- SPMC is capable of forwarding Secure interrupt to S-EL1 SP
+  which has preempted the normal world.
+- Interrupt is forwarded to SP using FFA_INTERRUPT interface.
+- Interrupt Number is not passed, S-EL1 SP can access the GIC registers directly.
+- Upon completion of Interrupt handling SP is expected to return to
+  SPMC using FFA_MSG_WAIT interface.
+- SPMC returns to normal world after interrupt handling is completed.
+
+In the scenario when secure interrupt occurs while the secure partition is running,
+the SPMC is not involved and the handling is implementation defined in the TOS.
+
+Non-Secure Interrupt handling
+-----------------------------
+
+The 'managed exit' scenario is the responsibility of the TOS and the SPMC is not involved.
+
+Test Secure Payload (TSP)
+=========================
+
+- TSP provides reference implementation of FF-A programming model.
+- TSP has the following support:
+
+  - SP initialization on all CPUs.
+  - Consuming Power Messages including CPU_ON, CPU_OFF, CPU_SUSPEND, CPU_SUSPEND_RESUME.
+  - Event Loop to receive Direct Requests.
+  - Sending Direct Response.
+  - Memory Sharing helper library.
+  - Ability to handle secure interrupt (timer).
+
+TSP Tests in CI
+---------------
+
+- TSP Tests are exercised in the TF-A CI using prebuilt FF-A Linux Test driver in NWd.
+- Expected output:
+

+Exception Handling Framework
+============================
+
+This document describes various aspects of handling exceptions by Runtime
+Firmware (BL31) that are targeted at EL3, other than SMCs. The |EHF| takes care
+of the following exceptions when targeted at EL3:
+
+-  Interrupts
+-  Synchronous External Aborts
+-  Asynchronous External Aborts
+
+|TF-A|'s handling of synchronous ``SMC`` exceptions raised from lower ELs is
+described in the :ref:`Firmware Design document <handling-an-smc>`. However, the
+|EHF| changes the semantics of `Interrupt handling`_ and :ref:`synchronous
+exceptions <Effect on SMC calls>` other than SMCs.
+
+The |EHF| is selected by setting the build option ``EL3_EXCEPTION_HANDLING`` to
+``1``, and is only available for AArch64 systems.
+
+Introduction
+------------
+
+Through various control bits in the ``SCR_EL3`` register, the Arm architecture
+allows for asynchronous exceptions to be routed to EL3. As described in the
+:ref:`Interrupt Management Framework` document, depending on the chosen
+interrupt routing model, TF-A appropriately sets the ``FIQ`` and ``IRQ`` bits of
+``SCR_EL3`` register to effect this routing. For most use cases, other than for
+the purpose of facilitating context switch between Normal and Secure worlds,
+FIQs and IRQs routed to EL3 are not required to be handled in EL3.
+
+However, the evolving system and standards landscape demands that various
+exceptions are targeted at and handled in EL3. For instance:
+
+-  Starting with ARMv8.2 architecture extension, many RAS features have been
+   introduced to the Arm architecture. With RAS features implemented, various
+   components of the system may use one of the asynchronous exceptions to signal
+   error conditions to PEs. These error conditions are of critical nature, and
+   it's imperative that corrective or remedial actions are taken at the earliest
+   opportunity. Therefore, a *Firmware-first Handling* approach is generally
+   followed in response to RAS events in the system.
+
+-  The Arm `SDEI specification`_ defines interfaces through which Normal world
+   interacts with the Runtime Firmware in order to request notification of
+   system events. The |SDEI| specification requires that these events are
+   notified even when the Normal world executes with the exceptions masked. This
+   too implies that firmware-first handling is required, where the events are
+   first received by the EL3 firmware, and then dispatched to Normal world
+   through purely software mechanism.
+
+For |TF-A|, firmware-first handling means that asynchronous exceptions are
+suitably routed to EL3, and the Runtime Firmware (BL31) is extended to include
+software components that are capable of handling those exceptions that target
+EL3. These components—referred to as *dispatchers* [#spd]_ in general—may
+choose to:
+
+.. _delegation-use-cases:
+
+-  Receive and handle exceptions entirely in EL3, meaning the exceptions
+   handling terminates in EL3.
+
+-  Receive exceptions, but handle part of the exception in EL3, and delegate the
+   rest of the handling to a dedicated software stack running at lower Secure
+   ELs. In this scheme, the handling spans various secure ELs.
+
+-  Receive exceptions, but handle part of the exception in EL3, and delegate
+   processing of the error to dedicated software stack running at lower secure
+   ELs (as above); additionally, the Normal world may also be required to
+   participate in the handling, or be notified of such events (for example, as
+   an |SDEI| event). In this scheme, exception handling potentially and
+   maximally spans all ELs in both Secure and Normal worlds.
+
+On any given system, all of the above handling models may be employed
+independently depending on platform choice and the nature of the exception
+received.
+
+.. [#spd] Not to be confused with :ref:`Secure Payload Dispatcher
+   <firmware_design_sel1_spd>`, which is an EL3 component that operates in EL3
+   on behalf of Secure OS.
+
+The role of Exception Handling Framework
+----------------------------------------
+
+Corollary to the use cases cited above, the primary role of the |EHF| is to
+facilitate firmware-first handling of exceptions on Arm systems. The |EHF| thus
+enables multiple exception dispatchers in runtime firmware to co-exist, register
+for, and handle exceptions targeted at EL3. This section outlines the basics,
+and the rest of this document expands the various aspects of the |EHF|.
+
+In order to arbitrate exception handling among dispatchers, the |EHF| operation
+is based on a priority scheme. This priority scheme is closely tied to how the
+Arm GIC architecture defines it, although it's applied to non-interrupt
+exceptions too (SErrors, for example).
+
+The platform is required to `partition`__ the Secure priority space into
+priority levels as applicable for the Secure software stack. It then assigns the
+dispatchers to one or more priority levels. The dispatchers then register
+handlers for the priority levels at runtime. A dispatcher can register handlers
+for more than one priority level.
+
+.. __: `Partitioning priority levels`_
+
+
+.. _ehf-figure:
+
+.. image:: ../resources/diagrams/draw.io/ehf.svg
+
+A priority level is *active* when a handler at that priority level is currently
+executing in EL3, or has delegated the execution to a lower EL. For interrupts,
+this is implicit when an interrupt is targeted and acknowledged at EL3, and the
+priority of the acknowledged interrupt is used to match its registered handler.
+The priority level is likewise implicitly deactivated when the interrupt
+handling concludes by EOIing the interrupt.
+
+Non-interrupt exceptions (SErrors, for example) don't have a notion of priority.
+In order for the priority arbitration to work, the |EHF| provides APIs in order
+for these non-interrupt exceptions to assume a priority, and to interwork with
+interrupts. Dispatchers handling such exceptions must therefore explicitly
+activate and deactivate the respective priority level as and when they're
+handled or delegated.
+
+Because priority activation and deactivation for interrupt handling is implicit
+and involves GIC priority masking, it's impossible for a lower priority
+interrupt to preempt a higher priority one. By extension, this means that a
+lower priority dispatcher cannot preempt a higher-priority one. Priority
+activation and deactivation for non-interrupt exceptions, however, has to be
+explicit. The |EHF| therefore disallows for lower priority level to be activated
+whilst a higher priority level is active, and would result in a panic.
+Likewise, a panic would result if it's attempted to deactivate a lower priority
+level when a higher priority level is active.
+
+In essence, priority level activation and deactivation conceptually works like a
+stack—priority levels stack up in strictly increasing fashion, and need to be
+unstacked in strictly the reverse order. For interrupts, the GIC ensures this is
+the case; for non-interrupts, the |EHF| monitors and asserts this. See
+`Transition of priority levels`_.
+
+.. _interrupt-handling:
+
+Interrupt handling
+------------------
+
+The |EHF| is a client of *Interrupt Management Framework*, and registers the
+top-level handler for interrupts that target EL3, as described in the
+:ref:`Interrupt Management Framework` document. This has the following
+implications:
+
+-  On GICv3 systems, when executing in S-EL1, pending Non-secure interrupts of
+   sufficient priority are signalled as FIQs, and therefore will be routed to
+   EL3. As a result, S-EL1 software cannot expect to handle Non-secure
+   interrupts at S-EL1. Essentially, this deprecates the routing mode described
+   as :ref:`CSS=0, TEL3=0 <EL3 interrupts>`.
+
+   In order for S-EL1 software to handle Non-secure interrupts while having
+   |EHF| enabled, the dispatcher must adopt a model where Non-secure interrupts
+   are received at EL3, but are then :ref:`synchronously <sp-synchronous-int>`
+   handled over to S-EL1.
+
+-  On GICv2 systems, it's required that the build option ``GICV2_G0_FOR_EL3`` is
+   set to ``1`` so that *Group 0* interrupts target EL3.
+
+-  While executing in Secure world, |EHF| sets GIC Priority Mask Register to the
+   lowest Secure priority. This means that no Non-secure interrupts can preempt
+   Secure execution. See `Effect on SMC calls`_ for more details.
+
+As mentioned above, with |EHF|, the platform is required to partition *Group 0*
+interrupts into distinct priority levels. A dispatcher that chooses to receive
+interrupts can then *own* one or more priority levels, and register interrupt
+handlers for them. A given priority level can be assigned to only one handler. A
+dispatcher may register more than one priority level.
+
+Dispatchers are assigned interrupt priority levels in two steps:
+
+.. _Partitioning priority levels:
+
+Partitioning priority levels
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Interrupts are associated to dispatchers by way of grouping and assigning
+interrupts to a priority level. In other words, all interrupts that are to
+target a particular dispatcher should fall in a particular priority level. For
+priority assignment:
+
+-  Of the 8 bits of priority that Arm GIC architecture permits, bit 7 must be 0
+   (secure space).
+
+-  Depending on the number of dispatchers to support, the platform must choose
+   to use the top *n* of the 7 remaining bits to identify and assign interrupts
+   to individual dispatchers. Choosing *n* bits supports up to 2\ :sup:`n`
+   distinct dispatchers. For example, by choosing 2 additional bits (i.e., bits
+   6 and 5), the platform can partition into 4 secure priority ranges: ``0x0``,
+   ``0x20``, ``0x40``, and ``0x60``. See `Interrupt handling example`_.
+
+.. note::
+
+   The Arm GIC architecture requires that a GIC implementation that supports two
+   security states must implement at least 32 priority levels; i.e., at least 5
+   upper bits of the 8 bits are writeable. In the scheme described above, when
+   choosing *n* bits for priority range assignment, the platform must ensure
+   that at least ``n+1`` top bits of GIC priority are writeable.
+
+The priority thus assigned to an interrupt is also used to determine the
+priority of delegated execution in lower ELs. Delegated execution in lower EL is
+associated with a priority level chosen with ``ehf_activate_priority()`` API
+(described `later`__). The chosen priority level also determines the interrupts
+masked while executing in a lower EL, therefore controls preemption of delegated
+execution.
+
+.. __: `ehf-apis`_
+
+The platform expresses the chosen priority levels by declaring an array of
+priority level descriptors. Each entry in the array is of type
+``ehf_pri_desc_t``, and declares a priority level, and shall be populated by the
+``EHF_PRI_DESC()`` macro.
+
+.. warning::
+
+   The macro ``EHF_PRI_DESC()`` installs the descriptors in the array at a
+   computed index, and not necessarily where the macro is placed in the array.
+   The size of the array might therefore be larger than what it appears to be.
+   The ``ARRAY_SIZE()`` macro therefore should be used to determine the size of
+   array.
+
+Finally, this array of descriptors is exposed to |EHF| via the
+``EHF_REGISTER_PRIORITIES()`` macro.
+
+Refer to the `Interrupt handling example`_ for usage. See also: `Interrupt
+Prioritisation Considerations`_.
+
+Programming priority
+~~~~~~~~~~~~~~~~~~~~
+
+The text in `Partitioning priority levels`_ only describes how the platform
+expresses the required levels of priority. It however doesn't choose interrupts
+nor program the required priority in GIC.
+
+The :ref:`Firmware Design guide<configuring-secure-interrupts>` explains methods
+for configuring secure interrupts. |EHF| requires the platform to enumerate
+interrupt properties (as opposed to just numbers) of Secure interrupts. The
+priority of secure interrupts must match that as determined in the
+`Partitioning priority levels`_ section above.
+
+See `Limitations`_, and also refer to `Interrupt handling example`_ for
+illustration.
+
+Registering handler
+-------------------
+
+Dispatchers register handlers for their priority levels through the following
+API:
+
+.. code:: c
+
+   int ehf_register_priority_handler(int pri, ehf_handler_t handler)
+
+The API takes two arguments:
+
+-  The priority level for which the handler is being registered;
+
+-  The handler to be registered. The handler must be aligned to 4 bytes.
+
+If a dispatcher owns more than one priority levels, it has to call the API for
+each of them.
+
+The API will succeed, and return ``0``, only if:
+
+-  There exists a descriptor with the priority level requested.
+
+-  There are no handlers already registered by a previous call to the API.
+
+Otherwise, the API returns ``-1``.
+
+The interrupt handler should have the following signature:
+
+.. code:: c
+
+   typedef int (*ehf_handler_t)(uint32_t intr_raw, uint32_t flags, void *handle,
+                   void *cookie);
+
+The parameters are as obtained from the top-level :ref:`EL3 interrupt handler
+<el3-runtime-firmware>`.
+
+The :ref:`SDEI dispatcher<SDEI: Software Delegated Exception Interface>`, for
+example, expects the platform to allocate two different priority levels—
+``PLAT_SDEI_CRITICAL_PRI``, and ``PLAT_SDEI_NORMAL_PRI`` —and registers the
+same handler to handle both levels.
+
+Interrupt handling example

+The following annotated snippet demonstrates how a platform might choose to
+assign interrupts to fictitious dispatchers:

+
+.. _Activating and Deactivating priorities:
+
+Activating and Deactivating priorities
+--------------------------------------
+
+A priority level is said to be *active* when an exception of that priority is
+being handled: for interrupts, this is implied when the interrupt is
+acknowledged; for non-interrupt exceptions, such as SErrors or :ref:`SDEI
+explicit dispatches <explicit-dispatch-of-events>`, this has to be done via
+calling ``ehf_activate_priority()``. See `Run-time flow`_.
+
+Conversely, when the dispatcher has reached a logical resolution for the cause
+of the exception, the corresponding priority level ought to be deactivated. As
+above, for interrupts, this is implied when the interrupt is EOId in the GIC;
+for other exceptions, this has to be done via calling
+``ehf_deactivate_priority()``.
+
+Thanks to `different provisions`__ for exception delegation, there are
+potentially more than one work flow for deactivation:
+
+.. __: `delegation-use-cases`_
+
+.. _deactivation workflows:
+
+-  The dispatcher has addressed the cause of the exception, and decided to take
+   no further action. In this case, the dispatcher's handler deactivates the
+   priority level before returning to the |EHF|. Runtime firmware, upon exit
+   through an ``ERET``, resumes execution before the interrupt occurred.
+
+-  The dispatcher has to delegate the execution to lower ELs, and the cause of
+   the exception can be considered resolved only when the lower EL returns
+   signals complete (via an ``SMC``) at a future point in time. The following
+   sequence ensues:
+
+   #. The dispatcher calls ``setjmp()`` to setup a jump point, and arranges to
+      enter a lower EL upon the next ``ERET``.
+
+   #. Through the ensuing ``ERET`` from runtime firmware, execution is delegated
+      to a lower EL.
+
+   #. The lower EL completes its execution, and signals completion via an
+      ``SMC``.
+
+   #. The ``SMC`` is handled by the same dispatcher that handled the exception
+      previously. Noticing the conclusion of exception handling, the dispatcher
+      does ``longjmp()`` to resume beyond the previous jump point.
+
+As mentioned above, the |EHF| provides the following APIs for activating and
+deactivating interrupt:
+
+.. _ehf-apis:
+
+-  ``ehf_activate_priority()`` activates the supplied priority level, but only
+   if the current active priority is higher than the given one; otherwise
+   panics. Also, to prevent interruption by physical interrupts of lower
+   priority, the |EHF| programs the *Priority Mask Register* corresponding to
+   the PE to the priority being activated.  Dispatchers typically only need to
+   call this when handling exceptions other than interrupts, and it needs to
+   delegate execution to a lower EL at a desired priority level.
+
+-  ``ehf_deactivate_priority()`` deactivates a given priority, but only if the
+   current active priority is equal to the given one; otherwise panics. |EHF|
+   also restores the *Priority Mask Register* corresponding to the PE to the
+   priority before the call to ``ehf_activate_priority()``. Dispatchers
+   typically only need to call this after handling exceptions other than
+   interrupts.
+
+The calling of APIs are subject to allowed `transitions`__. See also the
+`Run-time flow`_.
+
+.. __: `Transition of priority levels`_
+
+Transition of priority levels
+-----------------------------
+
+The |EHF| APIs ``ehf_activate_priority()`` and ``ehf_deactivate_priority()`` can
+be called to transition the current priority level on a PE. A given sequence of
+calls to these APIs are subject to the following conditions:
+
+-  For activation, the |EHF| only allows for the priority to increase (i.e.
+   numeric value decreases);
+
+-  For deactivation, the |EHF| only allows for the priority to decrease (i.e.
+   numeric value increases). Additionally, the priority being deactivated is
+   required to be the current priority.
+
+If these are violated, a panic will result.
+
+.. _Effect on SMC calls:
+
+Effect on SMC calls
+-------------------
+
+In general, Secure execution is regarded as more important than Non-secure
+execution. As discussed elsewhere in this document, EL3 execution, and any
+delegated execution thereafter, has the effect of raising GIC's priority
+mask—either implicitly by acknowledging Secure interrupts, or when dispatchers
+call ``ehf_activate_priority()``. As a result, Non-secure interrupts cannot
+preempt any Secure execution.
+
+SMCs from Non-secure world are synchronous exceptions, and are mechanisms for
+Non-secure world to request Secure services. They're broadly classified as
+*Fast* or *Yielding* (see `SMCCC`__).
+
+.. __: https://developer.arm.com/docs/den0028/latest
+
+-  *Fast* SMCs are atomic from the caller's point of view. I.e., they return
+   to the caller only when the Secure world has finished serving the request.
+   Any Non-secure interrupts that become pending meanwhile cannot preempt Secure
+   execution.
+
+-  *Yielding* SMCs carry the semantics of a preemptible, lower-priority request.
+   A pending Non-secure interrupt can preempt Secure execution handling a
+   Yielding SMC. I.e., the caller might observe a Yielding SMC returning when
+   either:
+
+   #. Secure world completes the request, and the caller would find ``SMC_OK``
+      as the return code.
+
+   #. A Non-secure interrupt preempts Secure execution. Non-secure interrupt is
+      handled, and Non-secure execution resumes after ``SMC`` instruction.
+
+   The dispatcher handling a Yielding SMC must provide a different return code
+   to the Non-secure caller to distinguish the latter case. This return code,
+   however, is not standardised (unlike ``SMC_UNKNOWN`` or ``SMC_OK``, for
+   example), so will vary across dispatchers that handle the request.
+
+For the latter case above, dispatchers before |EHF| expect Non-secure interrupts
+to be taken to S-EL1 [#irq]_, so would get a chance to populate the designated
+preempted error code before yielding to Non-secure world.
+
+The introduction of |EHF| changes the behaviour as described in `Interrupt
+handling`_.
+
+When |EHF| is enabled, in order to allow Non-secure interrupts to preempt
+Yielding SMC handling, the dispatcher must call ``ehf_allow_ns_preemption()``
+API. The API takes one argument, the error code to be returned to the Non-secure
+world upon getting preempted.
+
+.. [#irq] In case of GICv2, Non-secure interrupts while in S-EL1 were signalled
+          as IRQs, and in case of GICv3, FIQs.
+
+Build-time flow
+---------------
+
+Please refer to the `figure`__ above.
+
+.. __: `ehf-figure`_
+
+The build-time flow involves the following steps:
+
+#. Platform assigns priorities by installing priority level descriptors for
+   individual dispatchers, as described in `Partitioning priority levels`_.
+
+#. Platform provides interrupt properties to GIC driver, as described in
+   `Programming priority`_.
+
+#. Dispatcher calling ``ehf_register_priority_handler()`` to register an
+   interrupt handler.
+
+Also refer to the `Interrupt handling example`_.
+
+Run-time flow
+-------------
+
+.. _interrupt-flow:
+
+The following is an example flow for interrupts:
+
+#. The GIC driver, during initialization, iterates through the platform-supplied
+   interrupt properties (see `Programming priority`_), and configures the
+   interrupts. This programs the appropriate priority and group (Group 0) on
+   interrupts belonging to different dispatchers.
+
+#. The |EHF|, during its initialisation, registers a top-level interrupt handler
+   with the :ref:`Interrupt Management Framework<el3-runtime-firmware>` for EL3
+   interrupts. This also results in setting the routing bits in ``SCR_EL3``.
+
+#. When an interrupt belonging to a dispatcher fires, GIC raises an EL3/Group 0
+   interrupt, and is taken to EL3.
+
+#. The top-level EL3 interrupt handler executes. The handler acknowledges the
+   interrupt, reads its *Running Priority*, and from that, determines the
+   dispatcher handler.
+
+#. The |EHF| programs the *Priority Mask Register* of the PE to the priority of
+   the interrupt received.
+
+#. The |EHF| marks that priority level *active*, and jumps to the dispatcher
+   handler.
+
+#. Once the dispatcher handler finishes its job, it has to immediately
+   *deactivate* the priority level before returning to the |EHF|. See
+   `deactivation workflows`_.
+
+.. _non-interrupt-flow:
+
+The following is an example flow for exceptions that targets EL3 other than
+interrupt:
+
+#. The platform provides handlers for the specific kind of exception.
+
+#. The exception arrives, and the corresponding handler is executed.
+
+#. The handler calls ``ehf_activate_priority()`` to activate the required
+   priority level. This also has the effect of raising GIC priority mask, thus
+   preventing interrupts of lower priority from preempting the handling. The
+   handler may choose to do the handling entirely in EL3 or delegate to a lower
+   EL.
+
+#. Once exception handling concludes, the handler calls
+   ``ehf_deactivate_priority()`` to deactivate the priority level activated
+   earlier. This also has the effect of lowering GIC priority mask to what it
+   was before.
+
+Interrupt Prioritisation Considerations
+---------------------------------------
+
+The GIC priority scheme, by design, prioritises Secure interrupts over Normal
+world ones. The platform further assigns relative priorities amongst Secure
+dispatchers through |EHF|.
+
+As mentioned in `Partitioning priority levels`_, interrupts targeting distinct
+dispatchers fall in distinct priority levels. Because they're routed via the
+GIC, interrupt delivery to the PE is subject to GIC prioritisation rules. In
+particular, when an interrupt is being handled by the PE (i.e., the interrupt is
+in *Active* state), only interrupts of higher priority are signalled to the PE,
+even if interrupts of same or lower priority are pending. This has the side
+effect of one dispatcher being starved of interrupts by virtue of another
+dispatcher handling its (higher priority) interrupts.
+
+The |EHF| doesn't enforce a particular prioritisation policy, but the platform
+should carefully consider the assignment of priorities to dispatchers integrated
+into runtime firmware. The platform should sensibly delineate priority to
+various dispatchers according to their nature. In particular, dispatchers of
+critical nature (RAS, for example) should be assigned higher priority than
+others (|SDEI|, for example); and within |SDEI|, Critical priority
+|SDEI| should be assigned higher priority than Normal ones.
+
+Limitations
+-----------
+
+The |EHF| has the following limitations:
+
+-  Although there could be up to 128 Secure dispatchers supported by the GIC
+   priority scheme, the size of descriptor array exposed with
+   ``EHF_REGISTER_PRIORITIES()`` macro is currently limited to 32. This serves most
+   expected use cases. This may be expanded in the future, should use cases
+   demand so.
+
+-  The platform must ensure that the priority assigned to the dispatcher in the
+   exception descriptor and the programmed priority of interrupts handled by the
+   dispatcher match. The |EHF| cannot verify that this has been followed.

+Firmware Configuration Framework
+================================
+
+This document provides an overview of the |FCONF| framework.
+
+Introduction
+~~~~~~~~~~~~
+
+The Firmware CONfiguration Framework (|FCONF|) is an abstraction layer for
+platform specific data, allowing a "property" to be queried and a value
+retrieved without the requesting entity knowing what backing store is being used
+to hold the data.
+
+It is used to bridge new and old ways of providing platform-specific data.
+Today, information like the Chain of Trust is held within several, nested
+platform-defined tables. In the future, it may be provided as part of a device
+blob, along with the rest of the information about images to load.
+Introducing this abstraction layer will make migration easier and will preserve
+functionality for platforms that cannot / don't want to use device tree.
+
+Accessing properties
+~~~~~~~~~~~~~~~~~~~~
+
+Properties defined in the |FCONF| are grouped around namespaces and
+sub-namespaces: a.b.property.
+Examples namespace can be:
+
+- (|TBBR|) Chain of Trust data: tbbr.cot.trusted_boot_fw_cert
+- (|TBBR|) dynamic configuration info: tbbr.dyn_config.disable_auth
+- Arm io policies: arm.io_policies.bl2_image
+- GICv3 properties: hw_config.gicv3_config.gicr_base
+
+Properties can be accessed with the ``FCONF_GET_PROPERTY(a,b,property)`` macro.
+
+Defining properties
+~~~~~~~~~~~~~~~~~~~
+
+Properties composing the |FCONF| have to be stored in C structures. If
+properties originate from a different backend source such as a device tree,
+then the platform has to provide a ``populate()`` function which essentially
+captures the property and stores them into a corresponding |FCONF| based C
+structure.
+
+Such a ``populate()`` function is usually platform specific and is associated
+with a specific backend source. For example, a populator function which
+captures the hardware topology of the platform from the HW_CONFIG device tree.
+Hence each ``populate()`` function must be registered with a specific
+``config_type`` identifier. It broadly represents a logical grouping of
+configuration properties which is usually a device tree file.
+
+Example:
+ - FW_CONFIG: properties related to base address, maximum size and image id
+   of other DTBs etc.
+ - TB_FW: properties related to trusted firmware such as IO policies,
+   mbedtls heap info etc.
+ - HW_CONFIG: properties related to hardware configuration of the SoC
+   such as topology, GIC controller, PSCI hooks, CPU ID etc.
+
+Hence the ``populate()`` callback must be registered to the (|FCONF|) framework
+with the ``FCONF_REGISTER_POPULATOR()`` macro. This ensures that the function
+would be called inside the generic ``fconf_populate()`` function during
+initialization.
+
+::
+
+    int fconf_populate_topology(uintptr_t config)
+    {
+        /* read hw config dtb and fill soc_topology struct */
+    }
+
+    FCONF_REGISTER_POPULATOR(HW_CONFIG, topology, fconf_populate_topology);
+
+Then, a wrapper has to be provided to match the ``FCONF_GET_PROPERTY()`` macro:
+
+::
+
+    /* generic getter */
+    #define FCONF_GET_PROPERTY(a,b,property)	a##__##b##_getter(property)
+
+    /* my specific getter */
+    #define hw_config__topology_getter(prop) soc_topology.prop
+
+This second level wrapper can be used to remap the ``FCONF_GET_PROPERTY()`` to
+anything appropriate: structure, array, function, etc..
+
+To ensure a good interpretation of the properties, this documentation must
+explain how the properties are described for a specific backend. Refer to the
+:ref:`binding-document` section for more information and example.
+
+Loading the property device tree
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The ``fconf_load_config(image_id)`` must be called to load fw_config and
+tb_fw_config devices tree containing the properties' values. This must be done
+after the io layer is initialized, as the |DTB| is stored on an external
+device (FIP).
+
+.. uml:: ../../resources/diagrams/plantuml/fconf_bl1_load_config.puml
+
+Populating the properties
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Once a valid device tree is available, the ``fconf_populate(config)`` function

+
+Namespace guidance
+~~~~~~~~~~~~~~~~~~
+
+As mentioned above, properties are logically grouped around namespaces and
+sub-namespaces. The following concepts should be considered when adding new
+properties/namespaces.
+The framework differentiates two types of properties:
+
+ - Properties used inside common code.
+ - Properties used inside platform specific code.
+
+The first category applies to properties being part of the firmware and shared
+across multiple platforms. They should be globally accessible and defined
+inside the ``lib/fconf`` directory. The namespace must be chosen to reflect the
+feature/data abstracted.
+
+Example:
+ - |TBBR| related properties: tbbr.cot.bl2_id
+ - Dynamic configuration information: dyn_cfg.dtb_info.hw_config_id
+
+The second category should represent the majority of the properties defined
+within the framework: Platform specific properties. They must be accessed only
+within the platform API and are defined only inside the platform scope. The
+namespace must contain the platform name under which the properties defined
+belong.
+
+Example:
+ - Arm io framework: arm.io_policies.bl31_id

+Firmware Update (FWU)
+=====================
+
+This document describes the design of the various Firmware Update (FWU)
+mechanisms available in TF-A.
+
+1. PSA Firmware Update (PSA FWU)
+2. TBBR Firmware Update (TBBR FWU)
+
+PSA Firmware Update implements the specification of the same name (Arm document
+IHI 0093), which defines a standard firmware interface for installing firmware
+updates.
+On the other hand, TBBR Firmware Update only covers firmware recovery. Arguably,
+its name is somewhat misleading but the TBBR specification and terminology
+predates PSA FWU. Both mechanisms are complementary in the sense that PSA FWU
+assumes that the device has a backup or recovery capability in the event of a
+failed update, which can be fulfilled with TBBR FWU implementation.
+
+.. _PSA Firmware Update:
+
+PSA Firmware Update (PSA FWU)
+-----------------------------
+
+Introduction
+~~~~~~~~~~~~
+The `PSA FW update specification`_ defines the concepts of ``Firmware Update
+Client`` and ``Firmware Update Agent``.
+The new firmware images are provided by the ``Client`` to the ``Update Agent``
+to flash them in non-volatile storage.
+
+A common system design will place the ``Update Agent`` in the Secure-world
+while the ``Client`` executes in the Normal-world.
+The `PSA FW update specification`_ provides ABIs meant for a Normal-world
+entity aka ``Client`` to transmit the firmware images to the ``Update Agent``.
+
+Scope
+~~~~~
+The design of the ``Client`` and ``Update Agent`` is out of scope of this
+document.
+This document mainly covers ``Platform Boot`` details i.e. the role of
+the second stage Bootloader after FWU has been done by ``Client`` and
+``Update Agent``.
+
+Overview
+~~~~~~~~
+
+There are active and update banks in the non-volatile storage identified
+by the ``active_index`` and the ``update_index`` respectively.
+An active bank stores running firmware, whereas an update bank contains
+firmware updates.
+
+Once Firmwares are updated in the update bank of the non-volatile
+storage, then ``Update Agent`` marks the update bank as the active bank,
+and write updated FWU metadata in non-volatile storage.
+On subsequent reboot, the second stage Bootloader (BL2) performs the
+following actions:
+
+-  Read FWU metadata in memory
+-  Retrieve the image specification (offset and length) of updated images
+   present in non-volatile storage with the help of FWU metadata
+-  Set these image specification in the corresponding I/O policies of the
+   updated images using the FWU platform functions
+   ``plat_fwu_set_images_source()`` and ``plat_fwu_set_metadata_image_source()``,
+   please refer :ref:`Porting Guide`
+-  Use these I/O policies to read the images from this address into the memory
+
+By default, the platform uses the active bank of non-volatile storage to boot
+the images in ``trial state``. If images pass through the authentication check
+and also if the system successfully booted the Normal-world image then
+``Update Agent`` marks this update as accepted after further sanitisation
+checking at Normal-world.
+
+The second stage Bootloader (BL2) avoids upgrading the platform NV-counter until
+it's been confirmed that given update is accepted.
+
+The following sequence diagram shows platform-boot flow:
+
+.. image:: ../resources/diagrams/PSA-FWU.png
+
+If the platform fails to boot from active bank due to any reasons such
+as authentication failure or non-fuctionality of Normal-world software then the
+watchdog will reset to give a chance to the platform to fix the issue. This
+boot failure & reset sequence might be repeated up to ``trial state`` times.
+After that, the platform can decide to boot from the ``previous_active_index``
+bank.
+
+If the images still does not boot successfully from the ``previous_active_index``
+bank (e.g. due to ageing effect of non-volatile storage) then the platform can
+choose firmware recovery mechanism :ref:`TBBR Firmware Update` to bring system
+back to life.
+
+.. _TBBR Firmware Update:
+
+TBBR Firmware Update (TBBR FWU)
+-------------------------------
+
+Introduction
+~~~~~~~~~~~~
+
+This technique enables authenticated firmware to update firmware images from
+external interfaces such as USB, UART, SD-eMMC, NAND, NOR or Ethernet to SoC
+Non-Volatile memories such as NAND Flash, LPDDR2-NVM or any memory determined
+by the platform.
+This feature functions even when the current firmware in the system is corrupt
+or missing; it therefore may be used as a recovery mode. It may also be
+complemented by other, higher level firmware update software.
+
+FWU implements a specific part of the Trusted Board Boot Requirements (TBBR)
+specification, Arm DEN0006C-1. It should be used in conjunction with the
+:ref:`Trusted Board Boot` design document, which describes the image
+authentication parts of the Trusted Firmware-A (TF-A) TBBR implementation.
+
+It can be used as a last resort when all firmware updates that are carried out
+as part of the :ref:`PSA Firmware Update` procedure have failed to function.
+
+Scope
+~~~~~
+
+This document describes the secure world FWU design. It is beyond its scope to
+describe how normal world FWU images should operate. To implement normal world
+FWU images, please refer to the "Non-Trusted Firmware Updater" requirements in
+the TBBR.
+
+Overview
+~~~~~~~~
+
+The FWU boot flow is primarily mediated by BL1. Since BL1 executes in ROM, and
+it is usually desirable to minimize the amount of ROM code, the design allows
+some parts of FWU to be implemented in other secure and normal world images.
+Platform code may choose which parts are implemented in which images but the
+general expectation is:
+
+-  BL1 handles:
+
+   -  Detection and initiation of the FWU boot flow.
+   -  Copying images from non-secure to secure memory
+   -  FWU image authentication
+   -  Context switching between the normal and secure world during the FWU
+      process.
+
+-  Other secure world FWU images handle platform initialization required by
+   the FWU process.
+-  Normal world FWU images handle loading of firmware images from external
+   interfaces to non-secure memory.
+
+The primary requirements of the FWU feature are:
+
+#. Export a BL1 SMC interface to interoperate with other FWU images executing
+   at other Exception Levels.
+#. Export a platform interface to provide FWU common code with the information
+   it needs, and to enable platform specific FWU functionality. See the
+   :ref:`Porting Guide` for details of this interface.
+
+TF-A uses abbreviated image terminology for FWU images like for other TF-A
+images. See the :ref:`Image Terminology` document for an explanation of these
+terms.
+
+The following diagram shows the FWU boot flow for Arm development platforms.
+Arm CSS platforms like Juno have a System Control Processor (SCP), and these
+use all defined FWU images. Other platforms may use a subset of these.
+
+|Flow Diagram|
+
+Image Identification
+~~~~~~~~~~~~~~~~~~~~
+
+Each FWU image and certificate is identified by a unique ID, defined by the
+platform, which BL1 uses to fetch an image descriptor (``image_desc_t``) via a
+call to ``bl1_plat_get_image_desc()``. The same ID is also used to prepare the
+Chain of Trust (Refer to the :ref:`Authentication Framework & Chain of Trust`
+document for more information).
+
+The image descriptor includes the following information:
+
+-  Executable or non-executable image. This indicates whether the normal world
+   is permitted to request execution of a secure world FWU image (after
+   authentication). Secure world certificates and non-AP images are examples
+   of non-executable images.
+-  Secure or non-secure image. This indicates whether the image is
+   authenticated/executed in secure or non-secure memory.
+-  Image base address and size.
+-  Image entry point configuration (an ``entry_point_info_t``).
+-  FWU image state.
+
+BL1 uses the FWU image descriptors to:
+
+-  Validate the arguments of FWU SMCs
+-  Manage the state of the FWU process
+-  Initialize the execution state of the next FWU image.
+
+FWU State Machine
+~~~~~~~~~~~~~~~~~
+
+BL1 maintains state for each FWU image during FWU execution. FWU images at lower
+Exception Levels raise SMCs to invoke FWU functionality in BL1, which causes
+BL1 to update its FWU image state. The BL1 image states and valid state
+transitions are shown in the diagram below. Note that secure images have a more
+complex state machine than non-secure images.
+
+|FWU state machine|
+
+The following is a brief description of the supported states:
+
+-  RESET: This is the initial state of every image at the start of FWU.
+   Authentication failure also leads to this state. A secure
+   image may yield to this state if it has completed execution.
+   It can also be reached by using ``FWU_SMC_IMAGE_RESET``.
+
+-  COPYING: This is the state of a secure image while BL1 is copying it
+   in blocks from non-secure to secure memory.
+
+-  COPIED: This is the state of a secure image when BL1 has completed
+   copying it to secure memory.
+
+-  AUTHENTICATED: This is the state of an image when BL1 has successfully
+   authenticated it.
+
+-  EXECUTED: This is the state of a secure, executable image when BL1 has
+   passed execution control to it.
+
+-  INTERRUPTED: This is the state of a secure, executable image after it has
+   requested BL1 to resume normal world execution.

+
+This SMC passes execution control to an EL3 image described by the provided
+``entry_point_info_t`` structure. In the normal TF-A boot flow, BL2 invokes
+this SMC for BL1 to pass execution control to BL31.
+
+FWU_SMC_IMAGE_COPY
+^^^^^^^^^^^^^^^^^^
+
+::
+
+    Arguments:
+        uint32_t     function ID : 0x10
+        unsigned int image_id
+        uintptr_t    image_addr
+        unsigned int block_size
+        unsigned int image_size
+
+    Return:
+        int : 0 (Success)
+            : -ENOMEM
+            : -EPERM
+
+    Pre-conditions:
+        if (image_id is invalid) return -EPERM
+        if (image_id is non-secure image) return -EPERM
+        if (image_id state is not (RESET or COPYING)) return -EPERM
+        if (secure world caller) return -EPERM
+        if (image_addr + block_size overflows) return -ENOMEM
+        if (image destination address + image_size overflows) return -ENOMEM
+        if (source block is in secure memory) return -ENOMEM
+        if (source block is not mapped into BL1) return -ENOMEM
+        if (image_size > free secure memory) return -ENOMEM
+        if (image overlaps another image) return -EPERM
+
+This SMC copies the secure image indicated by ``image_id`` from non-secure memory
+to secure memory for later authentication. The image may be copied in a single
+block or multiple blocks. In either case, the total size of the image must be
+provided in ``image_size`` when invoking this SMC for the first time for each
+image; it is ignored in subsequent calls (if any) for the same image.
+
+The ``image_addr`` and ``block_size`` specify the source memory block to copy from.
+The destination address is provided by the platform code.
+
+If ``block_size`` is greater than the amount of remaining bytes to copy for this
+image then the former is truncated to the latter. The copy operation is then
+considered as complete and the FWU state machine transitions to the "COPIED"
+state. If there is still more to copy, the FWU state machine stays in or
+transitions to the COPYING state (depending on the previous state).
+
+When using multiple blocks, the source blocks do not necessarily need to be in
+contiguous memory.
+
+Once the SMC is handled, BL1 returns from exception to the normal world caller.
+
+FWU_SMC_IMAGE_AUTH
+^^^^^^^^^^^^^^^^^^
+
+::
+
+    Arguments:
+        uint32_t     function ID : 0x11
+        unsigned int image_id
+        uintptr_t    image_addr
+        unsigned int image_size
+
+    Return:
+        int : 0 (Success)
+            : -ENOMEM
+            : -EPERM
+            : -EAUTH
+
+    Pre-conditions:
+        if (image_id is invalid) return -EPERM
+        if (secure world caller)
+            if (image_id state is not RESET) return -EPERM
+            if (image_addr/image_size is not mapped into BL1) return -ENOMEM
+        else // normal world caller
+            if (image_id is secure image)
+                if (image_id state is not COPIED) return -EPERM
+            else // image_id is non-secure image
+                if (image_id state is not RESET) return -EPERM
+                if (image_addr/image_size is in secure memory) return -ENOMEM
+                if (image_addr/image_size not mapped into BL1) return -ENOMEM
+
+This SMC authenticates the image specified by ``image_id``. If the image is in the
+RESET state, BL1 authenticates the image in place using the provided
+``image_addr`` and ``image_size``. If the image is a secure image in the COPIED
+state, BL1 authenticates the image from the secure memory that BL1 previously
+copied the image into.
+
+BL1 returns from exception to the caller. If authentication succeeds then BL1
+sets the image state to AUTHENTICATED. If authentication fails then BL1 returns
+the -EAUTH error and sets the image state back to RESET.
+
+FWU_SMC_IMAGE_EXECUTE
+^^^^^^^^^^^^^^^^^^^^^
+
+::
+
+    Arguments:
+        uint32_t     function ID : 0x12
+        unsigned int image_id
+
+    Return:
+        int : 0 (Success)
+            : -EPERM
+
+    Pre-conditions:
+        if (image_id is invalid) return -EPERM
+        if (secure world caller) return -EPERM
+        if (image_id is non-secure image) return -EPERM
+        if (image_id is non-executable image) return -EPERM
+        if (image_id state is not AUTHENTICATED) return -EPERM
+
+This SMC initiates execution of a previously authenticated image specified by
+``image_id``, in the other security world to the caller. The current
+implementation only supports normal world callers initiating execution of a
+secure world image.
+
+BL1 saves the normal world caller's context, sets the secure image state to
+EXECUTED, and returns from exception to the secure image.
+
+FWU_SMC_IMAGE_RESUME
+^^^^^^^^^^^^^^^^^^^^
+
+::
+
+    Arguments:
+        uint32_t   function ID : 0x13
+        register_t image_param
+
+    Return:
+        register_t : image_param (Success)
+                   : -EPERM
+
+    Pre-conditions:
+        if (normal world caller and no INTERRUPTED secure image) return -EPERM
+
+This SMC resumes execution in the other security world while there is a secure
+image in the EXECUTED/INTERRUPTED state.
+
+For normal world callers, BL1 sets the previously interrupted secure image state
+to EXECUTED. For secure world callers, BL1 sets the previously executing secure
+image state to INTERRUPTED. In either case, BL1 saves the calling world's
+context, restores the resuming world's context and returns from exception into
+the resuming world. If the call is successful then the caller provided
+``image_param`` is returned to the resumed world, otherwise an error code is
+returned to the caller.
+
+FWU_SMC_SEC_IMAGE_DONE
+^^^^^^^^^^^^^^^^^^^^^^
+
+::
+
+    Arguments:
+        uint32_t function ID : 0x14
+
+    Return:
+        int : 0 (Success)
+            : -EPERM
+
+    Pre-conditions:
+        if (normal world caller) return -EPERM
+
+This SMC indicates completion of a previously executing secure image.
+
+BL1 sets the previously executing secure image state to the RESET state,
+restores the normal world context and returns from exception into the normal
+world.
+
+FWU_SMC_UPDATE_DONE
+^^^^^^^^^^^^^^^^^^^
+
+::
+
+    Arguments:
+        uint32_t   function ID : 0x15
+        register_t client_cookie
+
+    Return:
+        N/A
+
+This SMC completes the firmware update process. BL1 calls the platform specific
+function ``bl1_plat_fwu_done``, passing the optional argument ``client_cookie`` as
+a ``void *``. The SMC does not return.
+
+FWU_SMC_IMAGE_RESET
+^^^^^^^^^^^^^^^^^^^
+
+::
+
+    Arguments:
+        uint32_t     function ID : 0x16
+        unsigned int image_id
+
+    Return:
+        int : 0 (Success)
+            : -EPERM
+
+    Pre-conditions:
+        if (secure world caller) return -EPERM
+        if (image in EXECUTED) return -EPERM
+
+This SMC sets the state of an image to RESET and zeroes the memory used by it.
+
+This is only allowed if the image is not being executed.

+Granule Protection Tables Library
+=================================
+
+This document describes the design of the granule protection tables (GPT)
+library used by Trusted Firmware-A (TF-A). This library provides the APIs needed
+to initialize the GPTs based on a data structure containing information about
+the systems memory layout, configure the system registers to enable granule
+protection checks based on these tables, and transition granules between
+different PAS (physical address spaces) at runtime.
+
+Arm CCA adds two new security states for a total of four: root, realm, secure, and
+non-secure. In addition to new security states, corresponding physical address
+spaces have been added to control memory access for each state. The PAS access
+allowed to each security state can be seen in the table below.
+
+.. list-table:: Security states and PAS access rights
+   :widths: 25 25 25 25 25
+   :header-rows: 1
+
+   * -
+     - Root state
+     - Realm state
+     - Secure state
+     - Non-secure state
+   * - Root PAS
+     - yes
+     - no
+     - no
+     - no
+   * - Realm PAS
+     - yes
+     - yes
+     - no
+     - no
+   * - Secure PAS
+     - yes
+     - no
+     - yes
+     - no
+   * - Non-secure PAS
+     - yes
+     - yes
+     - yes
+     - yes
+
+The GPT can function as either a 1 level or 2 level lookup depending on how a
+PAS region is configured. The first step is the level 0 table, each entry in the
+level 0 table controls access to a relatively large region in memory (block
+descriptor), and the entire region can belong to a single PAS when a one step
+mapping is used, or a level 0 entry can link to a level 1 table where relatively
+small regions (granules) of memory can be assigned to different PAS with a 2
+step mapping. The type of mapping used for each PAS is determined by the user
+when setting up the configuration structure.
+
+Design Concepts and Interfaces
+------------------------------
+
+This section covers some important concepts and data structures used in the GPT
+library.
+
+There are three main parameters that determine how the tables are organized and
+function: the PPS (protected physical space) which is the total amount of
+protected physical address space in the system, PGS (physical granule size)
+which is how large each level 1 granule is, and L0GPTSZ (level 0 GPT size) which
+determines how much physical memory is governed by each level 0 entry. A granule
+is the smallest unit of memory that can be independently assigned to a PAS.
+
+L0GPTSZ is determined by the hardware and is read from the GPCCR_EL3 register.
+PPS and PGS are passed into the APIs at runtime and can be determined in
+whatever way is best for a given platform, either through some algorithm or hard
+coded in the firmware.
+
+GPT setup is split into two parts: table creation and runtime initialization. In
+the table creation step, a data structure containing information about the
+desired PAS regions is passed into the library which validates the mappings,
+creates the tables in memory, and enables granule protection checks. In the
+runtime initialization step, the runtime firmware locates the existing tables in
+memory using the GPT register configuration and saves important data to a
+structure used by the granule transition service which will be covered more
+below.
+
+In the reference implementation for FVP models, you can find an example of PAS
+region definitions in the file ``include/plat/arm/common/arm_pas_def.h``. Table
+creation API calls can be found in ``plat/arm/common/arm_bl2_setup.c`` and
+runtime initialization API calls can be seen in
+``plat/arm/common/arm_bl31_setup.c``.
+
+Defining PAS regions
+~~~~~~~~~~~~~~~~~~~~
+
+A ``pas_region_t`` structure is a way to represent a physical address space and
+its attributes that can be used by the GPT library to initialize the tables.
+
+This structure is composed of the following:
+
+#. The base physical address
+#. The region size
+#. The desired attributes of this memory region (mapping type, PAS type)
+
+See the ``pas_region_t`` type in ``include/lib/gpt_rme/gpt_rme.h``.
+
+The programmer should provide the API with an array containing ``pas_region_t``
+structures, then the library will check the desired memory access layout for
+validity and create tables to implement it.
+
+``pas_region_t`` is a public type, however it is recommended that the macros
+``GPT_MAP_REGION_BLOCK`` and ``GPT_MAP_REGION_GRANULE`` be used to populate
+these structures instead of doing it manually to reduce the risk of future
+compatibility issues. These macros take the base physical address, region size,
+and PAS type as arguments to generate the pas_region_t structure. As the names
+imply, ``GPT_MAP_REGION_BLOCK`` creates a region using only L0 mapping while
+``GPT_MAP_REGION_GRANULE`` creates a region using L0 and L1 mappings.
+
+Level 0 and Level 1 Tables
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The GPT initialization APIs require memory to be passed in for the tables to be
+constructed, ``gpt_init_l0_tables`` takes a memory address and size for building
+the level 0 tables and ``gpt_init_pas_l1_tables`` takes an address and size for
+building the level 1 tables which are linked from level 0 descriptors. The
+tables should have PAS type ``GPT_GPI_ROOT`` and a typical system might place
+its level 0 table in SRAM and its level 1 table(s) in DRAM.
+
+Granule Transition Service
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The Granule Transition Service allows memory mapped with GPT_MAP_REGION_GRANULE
+ownership to be changed using SMC calls. Non-secure granules can be transitioned
+to either realm or secure space, and realm and secure granules can be
+transitioned back to non-secure. This library only allows memory mapped as
+granules to be transitioned, memory mapped as blocks have their GPIs fixed after
+table creation.
+
+Library APIs
+------------
+
+The public APIs and types can be found in ``include/lib/gpt_rme/gpt_rme.h`` and this
+section is intended to provide additional details and clarifications.
+
+To create the GPTs and enable granule protection checks the APIs need to be
+called in the correct order and at the correct time during the system boot
+process.
+
+#. Firmware must enable the MMU.
+#. Firmware must call ``gpt_init_l0_tables`` to initialize the level 0 tables to
+   a default state, that is, initializing all of the L0 descriptors to allow all
+   accesses to all memory. The PPS is provided to this function as an argument.
+#. DDR discovery and initialization by the system, the discovered DDR region(s)
+   are then added to the L1 PAS regions to be initialized in the next step and
+   used by the GTSI at runtime.
+#. Firmware must call ``gpt_init_pas_l1_tables`` with a pointer to an array of
+   ``pas_region_t`` structures containing the desired memory access layout. The
+   PGS is provided to this function as an argument.
+#. Firmware must call ``gpt_enable`` to enable granule protection checks by
+   setting the correct register values.
+#. In systems that make use of the granule transition service, runtime
+   firmware must call ``gpt_runtime_init`` to set up the data structures needed
+   by the GTSI to find the tables and transition granules between PAS types.
+
+API Constraints
+~~~~~~~~~~~~~~~
+
+The values allowed by the API for PPS and PGS are enumerated types
+defined in the file ``include/lib/gpt_rme/gpt_rme.h``.
+
+Allowable values for PPS along with their corresponding size.
+
+* ``GPCCR_PPS_4GB`` (4GB protected space, 0x100000000 bytes)
+* ``GPCCR_PPS_64GB`` (64GB protected space, 0x1000000000 bytes)
+* ``GPCCR_PPS_1TB`` (1TB protected space, 0x10000000000 bytes)
+* ``GPCCR_PPS_4TB`` (4TB protected space, 0x40000000000 bytes)
+* ``GPCCR_PPS_16TB`` (16TB protected space, 0x100000000000 bytes)
+* ``GPCCR_PPS_256TB`` (256TB protected space, 0x1000000000000 bytes)
+* ``GPCCR_PPS_4PB`` (4PB protected space, 0x10000000000000 bytes)
+
+Allowable values for PGS along with their corresponding size.
+
+* ``GPCCR_PGS_4K`` (4KB granules, 0x1000 bytes)
+* ``GPCCR_PGS_16K`` (16KB granules, 0x4000 bytes)
+* ``GPCCR_PGS_64K`` (64KB granules, 0x10000 bytes)
+
+Allowable values for L0GPTSZ along with the corresponding size.
+
+* ``GPCCR_L0GPTSZ_30BITS`` (1GB regions, 0x40000000 bytes)
+* ``GPCCR_L0GPTSZ_34BITS`` (16GB regions, 0x400000000 bytes)
+* ``GPCCR_L0GPTSZ_36BITS`` (64GB regions, 0x1000000000 bytes)
+* ``GPCCR_L0GPTSZ_39BITS`` (512GB regions, 0x8000000000 bytes)
+
+Note that the value of the PPS, PGS, and L0GPTSZ definitions is an encoded value
+corresponding to the size, not the size itself. The decoded hex representations
+of the sizes have been provided for convenience.
+
+The L0 table memory has some constraints that must be taken into account.
+
+* The L0 table must be aligned to either the table size or 4096 bytes, whichever
+  is greater. L0 table size is the total protected space (PPS) divided by the
+  size of each L0 region (L0GPTSZ) multiplied by the size of each L0 descriptor
+  (8 bytes). ((PPS / L0GPTSZ) * 8)
+* The L0 memory size must be greater than or equal to the table size.
+* The L0 memory must fall within a PAS of type GPT_GPI_ROOT.
+
+The L1 memory also has some constraints.
+
+* The L1 tables must be aligned to their size. The size of each L1 table is the
+  size of each L0 region (L0GPTSZ) divided by the granule size (PGS) divided by
+  the granules controlled in each byte (2). ((L0GPTSZ / PGS) / 2)
+* There must be enough L1 memory supplied to build all requested L1 tables.
+* The L1 memory must fall within a PAS of type GPT_GPI_ROOT.
+
+If an invalid combination of parameters is supplied, the APIs will print an
+error message and return a negative value. The return values of APIs should be
+checked to ensure successful configuration.
+
+Sample Calculation for L0 memory size and alignment
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Let PPS=GPCCR_PPS_4GB and L0GPTSZ=GPCCR_L0GPTSZ_30BITS
+
+We can find the total L0 table size with ((PPS / L0GPTSZ) * 8)
+
+Substitute values to get this: ((0x100000000 / 0x40000000) * 8)
+
+And solve to get 32 bytes. In this case, 4096 is greater than 32, so the L0
+tables must be aligned to 4096 bytes.
+
+Sample calculation for L1 table size and alignment
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Let PGS=GPCCR_PGS_4K and L0GPTSZ=GPCCR_L0GPTSZ_30BITS
+
+We can find the size of each L1 table with ((L0GPTSZ / PGS) / 2).
+
+Substitute values: ((0x40000000 / 0x1000) / 2)
+
+And solve to get 0x20000 bytes per L1 table.

+Maximum Power Mitigation Mechanism (MPMM)
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+|MPMM| is an optional microarchitectural power management mechanism supported by
+some Arm Armv9-A cores, beginning with the Cortex-X2, Cortex-A710 and
+Cortex-A510 cores. This mechanism detects and limits high-activity events to
+assist in |SoC| processor power domain dynamic power budgeting and limit the
+triggering of whole-rail (i.e. clock chopping) responses to overcurrent
+conditions.
+
+|MPMM| is enabled on a per-core basis by the EL3 runtime firmware. The presence
+of |MPMM| cannot be determined at runtime by the firmware, and therefore the
+platform must expose this information through one of two possible mechanisms:
+
+- |FCONF|, controlled by the ``ENABLE_MPMM_FCONF`` build option.
+- A platform implementation of the ``plat_mpmm_topology`` function (the
+  default).
+
+See :ref:`Maximum Power Mitigation Mechanism (MPMM) Bindings` for documentation
+on the |FCONF| device tree bindings.
+
+.. warning::
+
+    |MPMM| exposes gear metrics through the auxiliary |AMU| counters. An
+    external power controller can use these metrics to budget SoC power by
+    limiting the number of cores that can execute higher-activity workloads or
+    switching to a different DVFS operating point. When this is the case, the

+Platform Interrupt Controller API
+=================================
+
+This document lists the optional platform interrupt controller API that
+abstracts the runtime configuration and control of interrupt controller from the
+generic code. The mandatory APIs are described in the
+:ref:`Porting Guide <porting_guide_imf_in_bl31>`.
+
+Function: unsigned int plat_ic_get_running_priority(void); [optional]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void
+    Return   : unsigned int
+
+This API should return the priority of the interrupt the PE is currently
+servicing. This must be be called only after an interrupt has already been
+acknowledged via ``plat_ic_acknowledge_interrupt``.
+
+In the case of Arm standard platforms using GIC, the *Running Priority Register*
+is read to determine the priority of the interrupt.
+
+Function: int plat_ic_is_spi(unsigned int id); [optional]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : unsigned int
+    Return   : int
+
+The API should return whether the interrupt ID (first parameter) is categorized
+as a Shared Peripheral Interrupt. Shared Peripheral Interrupts are typically
+associated to system-wide peripherals, and these interrupts can target any PE in
+the system.
+
+Function: int plat_ic_is_ppi(unsigned int id); [optional]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : unsigned int
+    Return   : int
+
+The API should return whether the interrupt ID (first parameter) is categorized
+as a Private Peripheral Interrupt. Private Peripheral Interrupts are typically
+associated with peripherals that are private to each PE. Interrupts from private
+peripherals target to that PE only.
+
+Function: int plat_ic_is_sgi(unsigned int id); [optional]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : unsigned int
+    Return   : int
+
+The API should return whether the interrupt ID (first parameter) is categorized
+as a Software Generated Interrupt. Software Generated Interrupts are raised by
+explicit programming by software, and are typically used in inter-PE
+communication. Secure SGIs are reserved for use by Secure world software.
+
+Function: unsigned int plat_ic_get_interrupt_active(unsigned int id); [optional]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : unsigned int
+    Return   : int
+
+This API should return the *active* status of the interrupt ID specified by the
+first parameter, ``id``.
+
+In case of Arm standard platforms using GIC, the implementation of the API reads
+the GIC *Set Active Register* to read and return the active status of the
+interrupt.
+
+Function: void plat_ic_enable_interrupt(unsigned int id); [optional]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : unsigned int
+    Return   : void
+
+This API should enable the interrupt ID specified by the first parameter,
+``id``. PEs in the system are expected to receive only enabled interrupts.
+
+In case of Arm standard platforms using GIC, the implementation of the API
+inserts barrier to make memory updates visible before enabling interrupt, and
+then writes to GIC *Set Enable Register* to enable the interrupt.
+
+Function: void plat_ic_disable_interrupt(unsigned int id); [optional]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : unsigned int
+    Return   : void
+
+This API should disable the interrupt ID specified by the first parameter,
+``id``. PEs in the system are not expected to receive disabled interrupts.
+
+In case of Arm standard platforms using GIC, the implementation of the API
+writes to GIC *Clear Enable Register* to disable the interrupt, and inserts
+barrier to make memory updates visible afterwards.
+
+Function: void plat_ic_set_interrupt_priority(unsigned int id, unsigned int priority); [optional]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : unsigned int
+    Argument : unsigned int
+    Return   : void
+
+This API should set the priority of the interrupt specified by first parameter
+``id`` to the value set by the second parameter ``priority``.
+
+In case of Arm standard platforms using GIC, the implementation of the API
+writes to GIC *Priority Register* set interrupt priority.
+
+Function: int plat_ic_has_interrupt_type(unsigned int type); [optional]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : unsigned int
+    Return   : int
+
+This API should return whether the platform supports a given interrupt type. The
+parameter ``type`` shall be one of ``INTR_TYPE_EL3``, ``INTR_TYPE_S_EL1``, or
+``INTR_TYPE_NS``.
+
+In case of Arm standard platforms using GICv3, the implementation of the API
+returns ``1`` for all interrupt types.
+
+In case of Arm standard platforms using GICv2, the API always return ``1`` for
+``INTR_TYPE_NS``. Return value for other types depends on the value of build
+option ``GICV2_G0_FOR_EL3``:
+
+- For interrupt type ``INTR_TYPE_EL3``:
+
+  - When ``GICV2_G0_FOR_EL3`` is ``0``, it returns ``0``, indicating no support
+    for EL3 interrupts.
+
+  - When ``GICV2_G0_FOR_EL3`` is ``1``, it returns ``1``, indicating support for
+    EL3 interrupts.
+
+- For interrupt type ``INTR_TYPE_S_EL1``:
+
+  - When ``GICV2_G0_FOR_EL3`` is ``0``, it returns ``1``, indicating support for
+    Secure EL1 interrupts.
+
+  - When ``GICV2_G0_FOR_EL3`` is ``1``, it returns ``0``, indicating no support
+    for Secure EL1 interrupts.
+
+Function: void plat_ic_set_interrupt_type(unsigned int id, unsigned int type); [optional]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : unsigned int
+    Argument : unsigned int
+    Return   : void
+
+This API should set the interrupt specified by first parameter ``id`` to the
+type specified by second parameter ``type``. The ``type`` parameter can be
+one of:
+
+- ``INTR_TYPE_NS``: interrupt is meant to be consumed by the Non-secure world.
+
+- ``INTR_TYPE_S_EL1``: interrupt is meant to be consumed by Secure EL1.
+
+- ``INTR_TYPE_EL3``: interrupt is meant to be consumed by EL3.
+
+In case of Arm standard platforms using GIC, the implementation of the API
+writes to the GIC *Group Register* and *Group Modifier Register* (only GICv3) to
+assign the interrupt to the right group.
+
+For GICv3:
+
+- ``INTR_TYPE_NS`` maps to Group 1 interrupt.
+
+- ``INTR_TYPE_S_EL1`` maps to Secure Group 1 interrupt.
+
+- ``INTR_TYPE_EL3`` maps to Secure Group 0 interrupt.
+
+For GICv2:
+
+- ``INTR_TYPE_NS`` maps to Group 1 interrupt.
+
+- When the build option ``GICV2_G0_FOR_EL3`` is set to ``0`` (the default),
+  ``INTR_TYPE_S_EL1`` maps to Group 0. Otherwise, ``INTR_TYPE_EL3`` maps to
+  Group 0 interrupt.
+
+Function: void plat_ic_raise_el3_sgi(int sgi_num, u_register_t target); [optional]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : int
+    Argument : u_register_t
+    Return   : void
+
+This API should raise an EL3 SGI. The first parameter, ``sgi_num``, specifies
+the ID of the SGI. The second parameter, ``target``, must be the MPIDR of the
+target PE.
+
+In case of Arm standard platforms using GIC, the implementation of the API
+inserts barrier to make memory updates visible before raising SGI, then writes
+to appropriate *SGI Register* in order to raise the EL3 SGI.
+
+Function: void plat_ic_set_spi_routing(unsigned int id, unsigned int routing_mode, u_register_t mpidr); [optional]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : unsigned int
+    Argument : unsigned int
+    Argument : u_register_t
+    Return   : void
+
+This API should set the routing mode of Share Peripheral Interrupt (SPI)
+specified by first parameter ``id`` to that specified by the second parameter
+``routing_mode``.
+
+The ``routing_mode`` parameter can be one of:
+
+- ``INTR_ROUTING_MODE_ANY`` means the interrupt can be routed to any PE in the
+  system. The ``mpidr`` parameter is ignored in this case.
+
+- ``INTR_ROUTING_MODE_PE`` means the interrupt is routed to the PE whose MPIDR
+  value is specified by the parameter ``mpidr``.
+
+In case of Arm standard platforms using GIC, the implementation of the API
+writes to the GIC *Target Register* (GICv2) or *Route Register* (GICv3) to set
+the routing.
+
+Function: void plat_ic_set_interrupt_pending(unsigned int id); [optional]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : unsigned int
+    Return   : void
+
+This API should set the interrupt specified by first parameter ``id`` to
+*Pending*.
+
+In case of Arm standard platforms using GIC, the implementation of the API
+inserts barrier to make memory updates visible before setting interrupt pending,
+and writes to the GIC *Set Pending Register* to set the interrupt pending
+status.
+
+Function: void plat_ic_clear_interrupt_pending(unsigned int id); [optional]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : unsigned int
+    Return   : void
+
+This API should clear the *Pending* status of the interrupt specified by first
+parameter ``id``.
+
+In case of Arm standard platforms using GIC, the implementation of the API
+writes to the GIC *Clear Pending Register* to clear the interrupt pending
+status, and inserts barrier to make memory updates visible afterwards.
+
+Function: unsigned int plat_ic_set_priority_mask(unsigned int id); [optional]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : unsigned int
+    Return   : int
+
+This API should set the priority mask (first parameter) in the interrupt
+controller such that only interrupts of higher priority than the supplied one
+may be signalled to the PE. The API should return the current priority value
+that it's overwriting.
+
+In case of Arm standard platforms using GIC, the implementation of the API
+inserts to order memory updates before updating mask, then writes to the GIC
+*Priority Mask Register*, and make sure memory updates are visible before
+potential trigger due to mask update.
+
+.. _plat_ic_get_interrupt_id:
+
+Function: unsigned int plat_ic_get_interrupt_id(unsigned int raw); [optional]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : unsigned int
+    Return   : unsigned int
+
+This API should extract and return the interrupt number from the raw value
+obtained by the acknowledging the interrupt (read using
+``plat_ic_acknowledge_interrupt()``). If the interrupt ID is invalid, this API
+should return ``INTR_ID_UNAVAILABLE``.
+
+In case of Arm standard platforms using GIC, the implementation of the API
+masks out the interrupt ID field from the acknowledged value from GIC.

+Reliability, Availability, and Serviceability (RAS) Extensions
+==============================================================
+
+This document describes |TF-A| support for Arm Reliability, Availability, and
+Serviceability (RAS) extensions. RAS is a mandatory extension for Armv8.2 and
+later CPUs, and also an optional extension to the base Armv8.0 architecture.
+
+In conjunction with the |EHF|, support for RAS extension enables firmware-first
+paradigm for handling platform errors: exceptions resulting from errors in
+Non-secure world are routed to and handled in EL3.
+Said errors are Synchronous External Abort (SEA), Asynchronous External Abort
+(signalled as SErrors), Fault Handling and Error Recovery interrupts.
+The |EHF| document mentions various :ref:`error handling
+use-cases <delegation-use-cases>` .
+
+For the description of Arm RAS extensions, Standard Error Records, and the
+precise definition of RAS terminology, please refer to the Arm Architecture
+Reference Manual. The rest of this document assumes familiarity with
+architecture and terminology.
+
+Overview
+--------
+
+As mentioned above, the RAS support in |TF-A| enables routing to and handling of
+exceptions resulting from platform errors in EL3. It allows the platform to
+define an External Abort handler, and to register RAS nodes and interrupts. RAS
+framework also provides `helpers`__ for accessing Standard Error Records as
+introduced by the RAS extensions.
+
+.. __: `Standard Error Record helpers`_
+
+The build option ``RAS_EXTENSION`` when set to ``1`` includes the RAS in run
+time firmware; ``EL3_EXCEPTION_HANDLING`` and ``HANDLE_EA_EL3_FIRST_NS`` must also
+be set ``1``. ``RAS_TRAP_NS_ERR_REC_ACCESS`` controls the access to the RAS
+error record registers from Non-secure.
+
+.. _ras-figure:
+
+.. image:: ../resources/diagrams/draw.io/ras.svg
+
+See more on `Engaging the RAS framework`_.
+
+Platform APIs
+-------------
+
+The RAS framework allows the platform to define handlers for External Abort,
+Uncontainable Errors, Double Fault, and errors rising from EL3 execution. Please
+refer to :ref:`RAS Porting Guide <External Abort handling and RAS Support>`.
+
+Registering RAS error records
+-----------------------------
+
+RAS nodes are components in the system capable of signalling errors to PEs
+through one one of the notification mechanisms—SEAs, SErrors, or interrupts. RAS
+nodes contain one or more error records, which are registers through which the
+nodes advertise various properties of the signalled error. Arm recommends that
+error records are implemented in the Standard Error Record format. The RAS
+architecture allows for error records to be accessible via system or
+memory-mapped registers.
+
+The platform should enumerate the error records providing for each of them:
+
+-  A handler to probe error records for errors;
+-  When the probing identifies an error, a handler to handle it;
+-  For memory-mapped error record, its base address and size in KB; for a system
+   register-accessed record, the start index of the record and number of
+   continuous records from that index;
+-  Any node-specific auxiliary data.
+
+With this information supplied, when the run time firmware receives one of the
+notification mechanisms, the RAS framework can iterate through and probe error
+records for error, and invoke the appropriate handler to handle it.
+
+The RAS framework provides the macros to populate error record information. The
+macros are versioned, and the latest version as of this writing is 1. These
+macros create a structure of type ``struct err_record_info`` from its arguments,
+which are later passed to probe and error handlers.
+
+For memory-mapped error records:
+
+.. code:: c
+
+    ERR_RECORD_MEMMAP_V1(base_addr, size_num_k, probe, handler, aux)
+
+And, for system register ones:
+
+.. code:: c
+
+    ERR_RECORD_SYSREG_V1(idx_start, num_idx, probe, handler, aux)
+
+The probe handler must have the following prototype:
+
+.. code:: c
+
+    typedef int (*err_record_probe_t)(const struct err_record_info *info,
+                    int *probe_data);
+
+The probe handler must return a non-zero value if an error was detected, or 0
+otherwise. The ``probe_data`` output parameter can be used to pass any useful
+information resulting from probe to the error handler (see `below`__). For
+example, it could return the index of the record.
+
+.. __: `Standard Error Record helpers`_
+
+The error handler must have the following prototype:
+
+.. code:: c
+
+    typedef int (*err_record_handler_t)(const struct err_record_info *info,
+               int probe_data, const struct err_handler_data *const data);
+
+The ``data`` constant parameter describes the various properties of the error,
+including the reason for the error, exception syndrome, and also ``flags``,
+``cookie``, and ``handle`` parameters from the :ref:`top-level exception handler
+<EL3 interrupts>`.
+
+The platform is expected populate an array using the macros above, and register
+the it with the RAS framework using the macro ``REGISTER_ERR_RECORD_INFO()``,
+passing it the name of the array describing the records. Note that the macro
+must be used in the same file where the array is defined.
+
+Standard Error Record helpers
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The |TF-A| RAS framework provides probe handlers for Standard Error Records, for
+both memory-mapped and System Register accesses:
+
+.. code:: c
+
+    int ras_err_ser_probe_memmap(const struct err_record_info *info,
+                int *probe_data);
+
+    int ras_err_ser_probe_sysreg(const struct err_record_info *info,
+                int *probe_data);
+
+When the platform enumerates error records, for those records in the Standard
+Error Record format, these helpers maybe used instead of rolling out their own.
+Both helpers above:
+
+-  Return non-zero value when an error is detected in a Standard Error Record;
+-  Set ``probe_data`` to the index of the error record upon detecting an error.
+
+Registering RAS interrupts
+--------------------------
+
+RAS nodes can signal errors to the PE by raising Fault Handling and/or Error
+Recovery interrupts. For the firmware-first handling paradigm for interrupts to
+work, the platform must setup and register with |EHF|. See `Interaction with
+Exception Handling Framework`_.
+
+For each RAS interrupt, the platform has to provide structure of type ``struct
+ras_interrupt``:
+
+-  Interrupt number;
+-  The associated error record information (pointer to the corresponding
+   ``struct err_record_info``);
+-  Optionally, a cookie.
+
+The platform is expected to define an array of ``struct ras_interrupt``, and
+register it with the RAS framework using the macro
+``REGISTER_RAS_INTERRUPTS()``, passing it the name of the array. Note that the
+macro must be used in the same file where the array is defined.
+
+The array of ``struct ras_interrupt`` must be sorted in the increasing order of
+interrupt number. This allows for fast look of handlers in order to service RAS
+interrupts.
+
+Double-fault handling
+---------------------
+
+A Double Fault condition arises when an error is signalled to the PE while
+handling of a previously signalled error is still underway. When a Double Fault
+condition arises, the Arm RAS extensions only require for handler to perform
+orderly shutdown of the system, as recovery may be impossible.
+
+The RAS extensions part of Armv8.4 introduced new architectural features to deal
+with Double Fault conditions, specifically, the introduction of ``NMEA`` and
+``EASE`` bits to ``SCR_EL3`` register. These were introduced to assist EL3
+software which runs part of its entry/exit routines with exceptions momentarily
+masked—meaning, in such systems, External Aborts/SErrors are not immediately
+handled when they occur, but only after the exceptions are unmasked again.
+
+|TF-A|, for legacy reasons, executes entire EL3 with all exceptions unmasked.
+This means that all exceptions routed to EL3 are handled immediately. |TF-A|
+thus is able to detect a Double Fault conditions in software, without needing
+the intended advantages of Armv8.4 Double Fault architecture extensions.
+
+Double faults are fatal, and terminate at the platform double fault handler, and
+doesn't return.
+
+Engaging the RAS framework
+--------------------------
+
+Enabling RAS support is a platform choice constructed from three distinct, but
+related, build options:
+
+-  ``RAS_EXTENSION=1`` includes the RAS framework in the run time firmware;
+
+-  ``EL3_EXCEPTION_HANDLING=1`` enables handling of exceptions at EL3. See
+   `Interaction with Exception Handling Framework`_;
+
+-  ``HANDLE_EA_EL3_FIRST_NS=1`` enables routing of External Aborts and SErrors,
+   resulting from errors in NS world, to EL3.
+
+The RAS support in |TF-A| introduces a default implementation of
+``plat_ea_handler``, the External Abort handler in EL3. When ``RAS_EXTENSION``
+is set to ``1``, it'll first call ``ras_ea_handler()`` function, which is the
+top-level RAS exception handler. ``ras_ea_handler`` is responsible for iterating
+to through platform-supplied error records, probe them, and when an error is
+identified, look up and invoke the corresponding error handler.
+
+Note that, if the platform chooses to override the ``plat_ea_handler`` function
+and intend to use the RAS framework, it must explicitly call
+``ras_ea_handler()`` from within.
+
+Similarly, for RAS interrupts, the framework defines
+``ras_interrupt_handler()``. The RAS framework arranges for it to be invoked
+when  a RAS interrupt taken at EL3. The function bisects the platform-supplied
+sorted array of interrupts to look up the error record information associated
+with the interrupt number. That error handler for that record is then invoked to
+handle the error.
+
+Interaction with Exception Handling Framework
+---------------------------------------------
+
+As mentioned in earlier sections, RAS framework interacts with the |EHF| to
+arbitrate handling of RAS exceptions with others that are routed to EL3. This
+means that the platform must partition a :ref:`priority level <Partitioning
+priority levels>` for handling RAS exceptions. The platform must then define
+the macro ``PLAT_RAS_PRI`` to the priority level used for RAS exceptions.
+Platforms would typically want to allocate the highest secure priority for
+RAS handling.
+
+Handling of both :ref:`interrupt <interrupt-flow>` and :ref:`non-interrupt
+<non-interrupt-flow>` exceptions follow the sequences outlined in the |EHF|
+documentation. I.e., for interrupts, the priority management is implicit; but
+for non-interrupt exceptions, they're explicit using :ref:`EHF APIs
+<Activating and Deactivating priorities>`.

+Realm Management Extension (RME)
+====================================
+
+FEAT_RME (or RME for short) is an Armv9-A extension and is one component of the
+`Arm Confidential Compute Architecture (Arm CCA)`_. TF-A supports RME starting
+from version 2.6. This chapter discusses the changes to TF-A to support RME and
+provides instructions on how to build and run TF-A with RME.
+
+RME support in TF-A
+---------------------
+
+The following diagram shows an Arm CCA software architecture with TF-A as the
+EL3 firmware. In the Arm CCA architecture there are two additional security
+states and address spaces: ``Root`` and ``Realm``. TF-A firmware runs in the
+Root world. In the realm world, a Realm Management Monitor firmware (RMM)
+manages the execution of Realm VMs and their interaction with the hypervisor.
+
+.. image:: ../resources/diagrams/arm-cca-software-arch.png
+
+RME is the hardware extension to support Arm CCA. To support RME, various
+changes have been introduced to TF-A. We discuss those changes below.
+
+Changes to translation tables library
+***************************************
+RME adds Root and Realm Physical address spaces. To support this, two new
+memory type macros, ``MT_ROOT`` and ``MT_REALM``, have been added to the
+:ref:`Translation (XLAT) Tables Library`. These macros are used to configure
+memory regions as Root or Realm respectively.
+
+.. note::
+
+ Only version 2 of the translation tables library supports the new memory
+ types.
+
+Changes to context management
+*******************************
+A new CPU context for the Realm world has been added. The existing
+:ref:`CPU context management API<PSCI Library Integration guide for Armv8-A
+AArch32 systems>` can be used to manage Realm context.
+
+Boot flow changes
+*******************
+In a typical TF-A boot flow, BL2 runs at Secure-EL1. However when RME is
+enabled, TF-A runs in the Root world at EL3. Therefore, the boot flow is
+modified to run BL2 at EL3 when RME is enabled. In addition to this, a
+Realm-world firmware (RMM) is loaded by BL2 in the Realm physical address
+space.
+
+The boot flow when RME is enabled looks like the following:
+
+1. BL1 loads and executes BL2 at EL3
+2. BL2 loads images including RMM
+3. BL2 transfers control to BL31
+4. BL31 initializes SPM (if SPM is enabled)
+5. BL31 initializes RMM
+6. BL31 transfers control to Normal-world software
+
+Granule Protection Tables (GPT) library
+*****************************************
+Isolation between the four physical address spaces is enforced by a process
+called Granule Protection Check (GPC) performed by the MMU downstream any
+address translation. GPC makes use of Granule Protection Table (GPT) in the
+Root world that describes the physical address space assignment of every
+page (granule). A GPT library that provides APIs to initialize GPTs and to
+transition granules between different physical address spaces has been added.
+More information about the GPT library can be found in the
+:ref:`Granule Protection Tables Library` chapter.
+
+RMM Dispatcher (RMMD)
+************************
+RMMD is a new standard runtime service that handles the switch to the Realm
+world. It initializes the RMM and handles Realm Management Interface (RMI)
+SMC calls from Non-secure and Realm worlds.
+
+There is a contract between RMM and RMMD that defines the arguments that the
+former needs to take in order to initialize and also the possible return values.
+This contract is defined in the RMM Boot Interface, which can be found at
+:ref:`rmm_el3_boot_interface`.
+
+There is also a specification of the runtime services provided by TF-A
+to RMM. This can be found at :ref:`runtime_services_and_interface`.
+
+Test Realm Payload (TRP)
+*************************
+TRP is a small test payload that runs at R-EL2 and implements a subset of
+the Realm Management Interface (RMI) commands to primarily test EL3 firmware
+and the interface between R-EL2 and EL3. When building TF-A with RME enabled,
+if a path to an RMM image is not provided, TF-A builds the TRP by default
+and uses it as RMM image.
+
+Building and running TF-A with RME
+------------------------------------
+
+This section describes how you can build and run TF-A with RME enabled.
+We assume you have all the :ref:`Prerequisites` to build TF-A.
+
+The following instructions show you how to build and run TF-A with RME
+for two scenarios:
+
+- Three-world execution: TF-A with TF-A Tests or Linux.
+
+  - NS (TF-A Test or Linux),
+  - Root (TF-A)
+  - Realm (RMM or TRP)
+
+- Four-world execution: TF-A, Hafnium and TF-A Tests or Linux.
+
+  - NS (TF-A Test or Linux),
+  - Root (TF-A)
+  - Realm (RMM or TRP)
+  - SPM (Hafnium)
+
+To run the tests, you need an FVP model. Please use the :ref:`latest version
+<Arm Fixed Virtual Platforms (FVP)>` of *FVP_Base_RevC-2xAEMvA* model.
+
+Three World Testing with TF-A Tests
+*************************************
+
+**1. Obtain and build TF-A Tests with Realm Payload**
+
+The full set of instructions to setup build host and build options for
+TF-A-Tests can be found in the `TFTF Getting Started`_.
+
+Use the following instructions to build TF-A with `TF-A Tests`_ as the
+non-secure payload (BL33).
+
+.. code:: shell
+
+ git clone https://git.trustedfirmware.org/TF-A/tf-a-tests.git
+ cd tf-a-tests
+ make CROSS_COMPILE=aarch64-none-elf- PLAT=fvp DEBUG=1 all pack_realm
+
+This produces a TF-A Tests binary (**tftf.bin**) with Realm payload packaged
+and **sp_layout.json** in the **build/fvp/debug** directory.
+
+**2. Obtain and build RMM Image**
+
+Please refer to the `RMM Getting Started`_ on how to setup
+Host Environment and build RMM.
+
+The below command shows how to build RMM using the default build options for FVP.
+
+.. code:: shell
+
+ git clone --recursive https://git.trustedfirmware.org/TF-RMM/tf-rmm.git
+ cd tf-rmm
+ cmake -DRMM_CONFIG=fvp_defcfg -S . -B build
+ cmake --build build
+
+This will generate **rmm.img** in **build** folder.
+
+**3. Build TF-A**
+
+The `TF-A Getting Started`_ has the necessary instructions to setup Host
+machine and build TF-A.
+
+To build for RME, set ``ENABLE_RME`` build option to 1 and provide the path to
+the RMM binary using the ``RMM`` build option.
+Currently, this feature is only supported for the FVP platform.
+
+.. note::
+
+ ENABLE_RME build option is currently experimental.
+
+If the ``RMM`` option is not used, then the Test Realm Payload (TRP) in TF-A
+will be built and used as the RMM.
+
+.. code:: shell
+
+ git clone https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git
+ cd trusted-firmware-a
+ make CROSS_COMPILE=aarch64-none-elf- \
+ PLAT=fvp \
+ ENABLE_RME=1 \
+ RMM=<path/to/rmm.img> \
+ FVP_HW_CONFIG_DTS=fdts/fvp-base-gicv3-psci-1t.dts \
+ DEBUG=1 \
+ BL33=<path/to/tftf.bin> \
+ all fip
+
+This produces **bl1.bin** and **fip.bin** binaries in the **build/fvp/debug** directory.

+RMM-EL3 Communication interface
+*******************************
+
+This document defines the communication interface between RMM and EL3.
+There are two parts in this interface: the boot interface and the runtime
+interface.
+
+The Boot Interface defines the ABI between EL3 and RMM when the CPU enters
+R-EL2 for the first time after boot. The cold boot interface defines the ABI
+for the cold boot path and the warm boot interface defines the same for the
+warm path.
+
+The RMM-EL3 runtime interface defines the ABI for EL3 services which can be
+invoked by RMM as well as the register save-restore convention when handling an
+SMC call from NS.
+
+The below sections discuss these interfaces more in detail.
+
+.. _rmm_el3_ifc_versioning:
+
+RMM-EL3 Interface versioning
+____________________________
+
+The RMM Boot and Runtime Interface uses a version number to check
+compatibility with the register arguments passed as part of Boot Interface and
+RMM-EL3 runtime interface.
+
+The Boot Manifest, discussed later in section :ref:`rmm_el3_boot_manifest`,
+uses a separate version number but with the same scheme.
+
+The version number is a 32-bit type with the following fields:
+
+.. csv-table::
+   :header: "Bits", "Value"
+
+   [0:15],``VERSION_MINOR``
+   [16:30],``VERSION_MAJOR``
+   [31],RES0
+
+The version numbers are sequentially increased and the rules for updating them
+are explained below:
+
+  - ``VERSION_MAJOR``: This value is increased when changes break
+    compatibility with previous versions. If the changes
+    on the ABI are compatible with the previous one, ``VERSION_MAJOR``
+    remains unchanged.
+
+  - ``VERSION_MINOR``: This value is increased on any change that is backwards
+    compatible with the previous version. When ``VERSION_MAJOR`` is increased,
+    ``VERSION_MINOR`` must be set to 0.
+
+  - ``RES0``: Bit 31 of the version number is reserved 0 as to maintain
+    consistency with the versioning schemes used in other parts of RMM.
+
+This document specifies the 0.1 version of Boot Interface ABI and RMM-EL3
+services specification and the 0.1 version of the Boot Manifest.
+
+.. _rmm_el3_boot_interface:
+
+RMM Boot Interface
+__________________
+
+This section deals with the Boot Interface part of the specification.
+
+One of the goals of the Boot Interface is to allow EL3 firmware to pass
+down into RMM certain platform specific information dynamically. This allows
+RMM to be less platform dependent and be more generic across platform
+variations. It also allows RMM to be decoupled from the other boot loader
+images in the boot sequence and remain agnostic of any particular format used
+for configuration files.
+
+The Boot Interface ABI defines a set of register conventions and
+also a memory based manifest file to pass information from EL3 to RMM. The
+boot manifest and the associated platform data in it can be dynamically created
+by EL3 and there is no restriction on how the data can be obtained (e.g by DTB,
+hoblist or other).
+
+The register convention and the manifest are versioned separately to manage
+future enhancements and compatibility.
+
+RMM completes the boot by issuing the ``RMM_BOOT_COMPLETE`` SMC (0xC40001CF)
+back to EL3. After the RMM has finished the boot process, it can only be
+entered from EL3 as part of RMI handling.
+
+If RMM returns an error during boot (in any CPU), then RMM must not be entered
+from any CPU.
+
+.. _rmm_cold_boot_interface:
+
+Cold Boot Interface
+~~~~~~~~~~~~~~~~~~~
+
+During cold boot RMM expects the following register values:
+
+.. csv-table::
+   :header: "Register", "Value"
+   :widths: 1, 5
+
+   x0,Linear index of this PE. This index starts from 0 and must be less than the maximum number of CPUs to be supported at runtime (see x2).
+   x1,Version for this Boot Interface as defined in :ref:`rmm_el3_ifc_versioning`.
+   x2,Maximum number of CPUs to be supported at runtime. RMM should ensure that it can support this maximum number.
+   x3,Base address for the shared buffer used for communication between EL3 firmware and RMM. This buffer must be of 4KB size (1 page). The boot manifest must be present at the base of this shared buffer during cold boot.
+
+During cold boot, EL3 firmware needs to allocate a 4K page that will be
+passed to RMM in x3. This memory will be used as shared buffer for communication
+between EL3 and RMM. It must be assigned to Realm world and must be mapped with
+Normal memory attributes (IWB-OWB-ISH) at EL3. At boot, this memory will be
+used to populate the Boot Manifest. Since the Boot Manifest can be accessed by
+RMM prior to enabling its MMU, EL3 must ensure that proper cache maintenance
+operations are performed after the Boot Manifest is populated.
+
+EL3 should also ensure that this shared buffer is always available for use by RMM
+during the lifetime of the system and that it can be used for runtime
+communication between RMM and EL3. For example, when RMM invokes attestation
+service commands in EL3, this buffer can be used to exchange data between RMM
+and EL3. It is also allowed for RMM to invoke runtime services provided by EL3
+utilizing this buffer during the boot phase, prior to return back to EL3 via
+RMM_BOOT_COMPLETE SMC.
+
+RMM should map this memory page into its Stage 1 page-tables using Normal
+memory attributes.
+
+During runtime, it is the RMM which initiates any communication with EL3. If that
+communication requires the use of the shared area, it is expected that RMM needs
+to do the necessary concurrency protection to prevent the use of the same buffer
+by other PEs.
+
+The following sequence diagram shows how a generic EL3 Firmware would boot RMM.
+
+.. image:: ../resources/diagrams/rmm_cold_boot_generic.png
+
+Warm Boot Interface
+~~~~~~~~~~~~~~~~~~~
+
+At warm boot, RMM is already initialized and only some per-CPU initialization
+is still pending. The only argument that is required by RMM at this stage is
+the CPU Id, which will be passed through register x0 whilst x1 to x3 are RES0.
+This is summarized in the following table:
+
+.. csv-table::
+   :header: "Register", "Value"
+   :widths: 1, 5
+
+   x0,Linear index of this PE. This index starts from 0 and must be less than the maximum number of CPUs to be supported at runtime (see x2).
+   x1 - x3,RES0
+
+Boot error handling and return values
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+After boot up and initialization, RMM returns control back to EL3 through a
+``RMM_BOOT_COMPLETE`` SMC call. The only argument of this SMC call will
+be returned in x1 and it will encode a signed integer with the error reason
+as per the following table:
+
+.. csv-table::
+   :header: "Error code", "Description", "ID"
+   :widths: 2 4 1
+
+   ``E_RMM_BOOT_SUCCESS``,Boot successful,0
+   ``E_RMM_BOOT_ERR_UNKNOWN``,Unknown error,-1
+   ``E_RMM_BOOT_VERSION_NOT_VALID``,Boot Interface version reported by EL3 is not supported by RMM,-2
+   ``E_RMM_BOOT_CPUS_OUT_OF_RAGE``,Number of CPUs reported by EL3 larger than maximum supported by RMM,-3
+   ``E_RMM_BOOT_CPU_ID_OUT_OF_RAGE``,Current CPU Id is higher or equal than the number of CPUs supported by RMM,-4
+   ``E_RMM_BOOT_INVALID_SHARED_BUFFER``,Invalid pointer to shared memory area,-5
+   ``E_RMM_BOOT_MANIFEST_VERSION_NOT_SUPPORTED``,Version reported by the boot manifest not supported by RMM,-6
+   ``E_RMM_BOOT_MANIFEST_DATA_ERROR``,Error parsing core boot manifest,-7
+
+For any error detected in RMM during cold or warm boot, RMM will return back to
+EL3 using ``RMM_BOOT_COMPLETE`` SMC with an appropriate error code. It is
+expected that EL3 will take necessary action to disable Realm world for further
+entry from NS Host on receiving an error. This will be done across all the PEs
+in the system so as to present a symmetric view to the NS Host. Any further
+warm boot by any PE should not enter RMM using the warm boot interface.
+
+.. _rmm_el3_boot_manifest:
+
+Boot Manifest
+~~~~~~~~~~~~~
+
+During cold boot, EL3 Firmware passes a memory boot manifest to RMM containing
+platform information.
+
+This boot manifest is versioned independently of the boot interface, to help
+evolve the boot manifest independent of the rest of Boot Manifest.
+The current version for the boot manifest is ``v0.1`` and the rules explained
+in :ref:`rmm_el3_ifc_versioning` apply on this version as well.
+
+The boot manifest is divided into two different components:
+
+   - Core Manifest: This is the generic parameters passed to RMM by EL3 common to all platforms.
+   - Platform data: This is defined by the platform owner and contains information specific to that platform.
+
+For the current version of the manifest, the core manifest contains a pointer
+to the platform data. EL3 must ensure that the whole boot manifest,
+including the platform data, if available, fits inside the RMM EL3 shared
+buffer.
+
+For the type specification of the RMM Boot Manifest v0.1, refer to
+:ref:`rmm_el3_manifest_struct`
+
+.. _runtime_services_and_interface:
+
+RMM-EL3 Runtime Interface
+__________________________
+
+This section defines the RMM-EL3 runtime interface which specifies the ABI for
+EL3 services expected by RMM at runtime as well as the register save and
+restore convention between EL3 and RMM as part of RMI call handling. It is
+important to note that RMM is allowed to invoke EL3-RMM runtime interface
+services during the boot phase as well. The EL3 runtime service handling must
+not result in a world switch to another world unless specified. Both the RMM
+and EL3 are allowed to make suitable optimizations based on this assumption.
+
+If the interface requires the use of memory, then the memory references should
+be within the shared buffer communicated as part of the boot interface. See
+:ref:`rmm_cold_boot_interface` for properties of this shared buffer which both
+EL3 and RMM must adhere to.
+
+RMM-EL3 runtime service return codes
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The return codes from EL3 to RMM is a 32 bit signed integer which encapsulates
+error condition as described in the following table:
+
+.. csv-table::
+   :header: "Error code", "Description", "ID"
+   :widths: 2 4 1
+
+   ``E_RMM_OK``,No errors detected,0
+   ``E_RMM_UNK``,Unknown/Generic error,-1
+   ``E_RMM_BAD_ADDR``,The value of an address used as argument was invalid,-2
+   ``E_RMM_BAD_PAS``,Incorrect PAS,-3
+   ``E_RMM_NOMEM``,Not enough memory to perform an operation,-4
+   ``E_RMM_INVAL``,The value of an argument was invalid,-5
+
+If multiple failure conditions are detected in an RMM to EL3 command, then EL3
+is allowed to return an error code corresponding to any of the failure
+conditions.
+

+RMM-EL3 world switch register save restore convention
+_____________________________________________________
+
+As part of NS world switch, EL3 is expected to maintain a register context
+specific to each world and will save and restore the registers
+appropriately. This section captures the contract between EL3 and RMM on the
+register set to be saved and restored.
+
+EL3 must maintain a separate register context for the following:
+
+   #. General purpose registers (x0-x30) and ``sp_el0``, ``sp_el2`` stack pointers
+   #. EL2 system register context for all enabled features by EL3. These include system registers with the ``_EL2`` prefix. The EL2 physical and virtual timer registers must not be included in this.
+
+As part of SMC forwarding between the NS world and Realm world, EL3 allows x0-x7 to be passed
+as arguments to Realm and x0-x4 to be used for return arguments back to Non Secure.
+As per SMCCCv1.2, x4 must be preserved if not being used as return argument by the SMC function
+and it is the responsibility of RMM to preserve this or use this as a return argument.
+EL3 will always copy x0-x4 from Realm context to NS Context.
+
+EL3 will not save some registers as mentioned in the below list. It is the
+responsibility of RMM to ensure that these are appropriately saved if the
+Realm World makes use of them:
+
+   #. FP/SIMD registers
+   #. SVE registers
+   #. SME registers
+   #. EL1/0 registers
+
+It is the responsibility of EL3 that any other registers other than the ones mentioned above
+will not be leaked to the NS Host and to maintain the confidentiality of the Realm World.
+
+SMCCC v1.3 allows NS world to specify whether SVE context is in use. In this
+case, RMM could choose to not save the incoming SVE context but must ensure
+to clear SVE registers if they have been used in Realm World. The same applies
+to SME registers.

+Library at ROM
+==============
+
+This document provides an overview of the "library at ROM" implementation in
+Trusted Firmware-A (TF-A).
+
+Introduction
+~~~~~~~~~~~~
+
+The "library at ROM" feature allows platforms to build a library of functions to
+be placed in ROM. This reduces SRAM usage by utilising the available space in
+ROM. The "library at ROM" contains a jump table with the list of functions that
+are placed in ROM. The capabilities of the "library at ROM" are:
+
+1. Functions can be from one or several libraries.
+
+2. Functions can be patched after they have been programmed into ROM.
+
+3. Platform-specific libraries can be placed in ROM.
+
+4. Functions can be accessed by one or more BL images.
+
+Index file
+~~~~~~~~~~
+
+.. image:: ../resources/diagrams/romlib_design.png
+    :width: 600
+
+Library at ROM is described by an index file with the list of functions to be
+placed in ROM. The index file is platform specific and its format is:
+
+::
+
+    lib function    [patch]
+
+    lib      -- Name of the library the function belongs to
+    function -- Name of the function to be placed in library at ROM
+    [patch]  -- Option to patch the function
+
+It is also possible to insert reserved spaces in the list by using the keyword
+"reserved" rather than the "lib" and "function" names as shown below:
+
+::
+
+    reserved
+
+The reserved spaces can be used to add more functions in the future without
+affecting the order and location of functions already existing in the jump
+table. Also, for additional flexibility and modularity, the index file can
+include other index files.
+
+For an index file example, refer to ``lib/romlib/jmptbl.i``.
+
+Wrapper functions
+~~~~~~~~~~~~~~~~~
+
+.. image:: ../resources/diagrams/romlib_wrapper.png
+    :width: 600
+
+When invoking a function of the "library at ROM", the calling sequence is as
+follows:
+
+BL image --> wrapper function --> jump table entry --> library at ROM
+
+The index file is used to create a jump table which is placed in ROM. Then, the
+wrappers refer to the jump table to call the "library at ROM" functions. The
+wrappers essentially contain a branch instruction to the jump table entry
+corresponding to the original function. Finally, the original function in the BL
+image(s) is replaced with the wrapper function.
+
+The "library at ROM" contains a necessary init function that initialises the
+global variables defined by the functions inside "library at ROM".
+
+Script
+~~~~~~
+
+There is a ``romlib_generate.py`` Python script that generates the necessary
+files for the "library at ROM" to work. It implements multiple functions:
+
+1. ``romlib_generate.py gentbl [args]`` - Generates the jump table by parsing
+   the index file.
+
+2. ``romlib_generator.py genvar [args]`` - Generates the jump table global
+   variable (**not** the jump table itself) with the absolute address in ROM.
+   This global variable is, basically, a pointer to the jump table.
+
+3. ``romlib_generator.py genwrappers [args]`` - Generates a wrapper function for
+   each entry in the index file except for the ones that contain the keyword
+   ``patch``. The generated wrapper file is called ``<fn_name>.s``.
+
+4. ``romlib_generator.py pre [args]`` - Preprocesses the index file which means
+   it resolves all the include commands in the file recursively. It can also
+   generate a dependency file of the included index files which can be directly
+   used in makefiles.
+
+Each ``romlib_generate.py`` function has its own manual which is accessible by
+runing ``romlib_generator.py [function] --help``.
+
+``romlib_generate.py`` requires Python 3 environment.
+
+
+Patching of functions in library at ROM
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The ``romlib_generator.py genwrappers`` does not generate wrappers for the
+entries in the index file that contain the keyword ``patch``. Thus, it allows
+calling the function from the actual library by breaking the link to the
+"library at ROM" version of this function.
+
+The calling sequence for a patched function is as follows:
+
+BL image --> function
+
+Memory impact
+~~~~~~~~~~~~~
+
+Using library at ROM will modify the memory layout of the BL images:
+
+- The ROM library needs a page aligned RAM section to hold the RW data. This
+  section is defined by the ROMLIB_RW_BASE and ROMLIB_RW_END macros.
+  On Arm platforms a section of 1 page (0x1000) is allocated at the top of SRAM.
+  This will have for effect to shift down all the BL images by 1 page.
+
+- Depending on the functions moved to the ROM library, the size of the BL images
+  will be reduced.
+  For example: moving MbedTLS function into the ROM library reduces BL1 and
+  BL2, but not BL31.
+
+- This change in BL images size can be taken into consideration to optimize the
+  memory layout when defining the BLx_BASE macros.
+
+Build library at ROM
+~~~~~~~~~~~~~~~~~~~~~
+
+The environment variable ``CROSS_COMPILE`` must be set appropriately. Refer to
+:ref:`Performing an Initial Build` for more information about setting this
+variable.
+
+In the below example the usage of ROMLIB together with mbed TLS is demonstrated
+to showcase the benefits of library at ROM - it's not mandatory.

+SDEI: Software Delegated Exception Interface
+============================================
+
+This document provides an overview of the SDEI dispatcher implementation in
+Trusted Firmware-A (TF-A).
+
+Introduction
+------------
+
+Software Delegated Exception Interface (|SDEI|) is an Arm specification for
+Non-secure world to register handlers with firmware to receive notifications
+about system events. Firmware will first receive the system events by way of
+asynchronous exceptions and, in response, arranges for the registered handler to
+execute in the Non-secure EL.
+
+Normal world software that interacts with the SDEI dispatcher (makes SDEI
+requests and receives notifications) is referred to as the *SDEI Client*. A
+client receives the event notification at the registered handler even when it
+was executing with exceptions masked. The list of SDEI events available to the
+client are specific to the platform [#std-event]_. See also `Determining client
+EL`_.
+
+.. _general SDEI dispatch:
+
+The following figure depicts a general sequence involving SDEI client executing
+at EL2 and an event dispatch resulting from the triggering of a bound interrupt.
+A commentary is provided below:
+
+.. uml:: ../resources/diagrams/plantuml/sdei_general.puml
+
+As part of initialisation, the SDEI client binds a Non-secure interrupt [1], and
+the SDEI dispatcher returns a platform dynamic event number [2]. The client then
+registers a handler for that event [3], enables the event [5], and unmasks all
+events on the current PE [7]. This sequence is typical of an SDEI client, but it
+may involve additional SDEI calls.
+
+At a later point in time, when the bound interrupt triggers [9], it's trapped to
+EL3. The interrupt is handed over to the SDEI dispatcher, which then arranges to
+execute the registered handler [10]. The client terminates its execution with
+``SDEI_EVENT_COMPLETE`` [11], following which the dispatcher resumes the
+original EL2 execution [13]. Note that the SDEI interrupt remains active until
+the client handler completes, at which point EL3 does EOI [12].
+
+Other than events bound to interrupts, as depicted in the sequence above, SDEI
+events can be explicitly dispatched in response to other exceptions, for
+example, upon receiving an *SError* or *Synchronous External Abort*. See
+`Explicit dispatch of events`_.
+
+The remainder of this document only discusses the design and implementation of
+SDEI dispatcher in TF-A, and assumes that the reader is familiar with the SDEI
+specification, the interfaces, and their requirements.
+
+Defining events
+---------------
+
+A platform choosing to include the SDEI dispatcher must also define the events
+available on the platform, along with their attributes.
+
+The platform is expected to provide two arrays of event descriptors: one for
+private events, and another for shared events. The SDEI dispatcher provides
+``SDEI_PRIVATE_EVENT()`` and ``SDEI_SHARED_EVENT()`` macros to populate the
+event descriptors. Both macros take 3 arguments:
+
+-  The event number: this must be a positive 32-bit integer.
+
+-  For an event that has a backing interrupt, the interrupt number the event is
+   bound to:
+
+   - If it's not applicable to an event, this shall be left as ``0``.
+
+   - If the event is dynamic, this should be specified as ``SDEI_DYN_IRQ``.
+
+-  A bit map of `Event flags`_.
+
+To define event 0, the macro ``SDEI_DEFINE_EVENT_0()`` should be used. This
+macro takes only one parameter: an SGI number to signal other PEs.
+
+To define an event that's meant to be explicitly dispatched (i.e., not as a
+result of receiving an SDEI interrupt), the macro ``SDEI_EXPLICIT_EVENT()``
+should be used. It accepts two parameters:
+
+-  The event number (as above);
+
+-  Event priority: ``SDEI_MAPF_CRITICAL`` or ``SDEI_MAPF_NORMAL``, as described
+   below.
+
+Once the event descriptor arrays are defined, they should be exported to the
+SDEI dispatcher using the ``REGISTER_SDEI_MAP()`` macro, passing it the pointers
+to the private and shared event descriptor arrays, respectively. Note that the
+``REGISTER_SDEI_MAP()`` macro must be used in the same file where the arrays are
+defined.
+
+Regarding event descriptors:
+
+-  For Event 0:
+
+   - There must be exactly one descriptor in the private array, and none in the
+     shared array.
+
+   - The event should be defined using ``SDEI_DEFINE_EVENT_0()``.
+
+   - Must be bound to a Secure SGI on the platform.
+
+-  Explicit events should only be used in the private array.
+
+-  Statically bound shared and private interrupts must be bound to shared and
+   private interrupts on the platform, respectively. See the section on
+   `Configuration within Exception Handling Framework`_.
+
+-  Both arrays should be one-dimensional. The ``REGISTER_SDEI_MAP()`` macro
+   takes care of replicating private events for each PE on the platform.
+
+-  Both arrays must be sorted in the increasing order of event number.
+
+The SDEI specification doesn't have provisions for discovery of available events
+on the platform. The list of events made available to the client, along with
+their semantics, have to be communicated out of band; for example, through
+Device Trees or firmware configuration tables.
+
+See also `Event definition example`_.
+
+Event flags
+~~~~~~~~~~~
+
+Event flags describe the properties of the event. They are bit maps that can be
+``OR``\ ed to form parameters to macros that define events (see
+`Defining events`_).
+
+-  ``SDEI_MAPF_DYNAMIC``: Marks the event as dynamic. Dynamic events can be

+        /* Event 0 definition */
+        SDEI_DEFINE_EVENT_0(8),

+        /* PPI */
+        SDEI_PRIVATE_EVENT(8, 23, SDEI_MAPF_BOUND),

+   };
+
+   /* Export SDEI events */
+   REGISTER_SDEI_MAP(plat_private_sdei, plat_shared_sdei);
+
+Configuration within Exception Handling Framework
+-------------------------------------------------
+
+The SDEI dispatcher functions alongside the Exception Handling Framework. This
+means that the platform must assign priorities to both Normal and Critical SDEI
+interrupts for the platform:
+
+-  Install priority descriptors for Normal and Critical SDEI interrupts.
+
+-  For those interrupts that are statically bound (i.e. events defined as having
+   the ``SDEI_MAPF_BOUND`` property), enumerate their properties for the GIC
+   driver to configure interrupts accordingly.
+
+   The interrupts must be configured to target EL3. This means that they should
+   be configured as *Group 0*.  Additionally, on GICv2 systems, the build option
+   ``GICV2_G0_FOR_EL3`` must be set to ``1``.
+
+See also :ref:`porting_guide_sdei_requirements`.
+
+Determining client EL
+---------------------
+
+The SDEI specification requires that the *physical* SDEI client executes in the
+highest Non-secure EL implemented on the system. This means that the dispatcher
+will only allow SDEI calls to be made from:
+
+-  EL2, if EL2 is implemented. The Hypervisor is expected to implement a
+   *virtual* SDEI dispatcher to support SDEI clients in Guest Operating Systems
+   executing in Non-secure EL1.
+
+-  Non-secure EL1, if EL2 is not implemented or disabled.
+
+See the function ``sdei_client_el()`` in ``sdei_private.h``.
+
+.. _explicit-dispatch-of-events:
+
+Explicit dispatch of events
+---------------------------
+
+Typically, an SDEI event dispatch is caused by the PE receiving interrupts that
+are bound to an SDEI event. However, there are cases where the Secure world
+requires dispatch of an SDEI event as a direct or indirect result of a past
+activity, such as receiving a Secure interrupt or an exception.
+
+The SDEI dispatcher implementation provides ``sdei_dispatch_event()`` API for
+this purpose. The API has the following signature:
+
+.. code:: c
+
+        int sdei_dispatch_event(int ev_num);
+
+The parameter ``ev_num`` is the event number to dispatch. The API returns ``0``
+on success, or ``-1`` on failure.
+
+The following figure depicts a scenario involving explicit dispatch of SDEI
+event. A commentary is provided below:
+
+.. uml:: ../resources/diagrams/plantuml/sdei_explicit_dispatch.puml
+
+As part of initialisation, the SDEI client registers a handler for a platform
+event [1], enables the event [3], and unmasks the current PE [5]. Note that,
+unlike in `general SDEI dispatch`_, this doesn't involve interrupt binding, as
+bound or dynamic events can't be explicitly dispatched (see the section below).
+
+At a later point in time, a critical event [#critical-event]_ is trapped into
+EL3 [7]. EL3 performs a first-level triage of the event, and a RAS component
+assumes further handling [8]. The dispatch completes, but intends to involve
+Non-secure world in further handling, and therefore decides to explicitly
+dispatch an event [10] (which the client had already registered for [1]). The
+rest of the sequence is similar to that in the `general SDEI dispatch`_: the
+requested event is dispatched to the client (assuming all the conditions are
+met), and when the handler completes, the preempted execution resumes.
+
+Conditions for event dispatch
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+All of the following requirements must be met for the API to return ``0`` and
+event to be dispatched:
+
+-  SDEI events must be unmasked on the PE. I.e. the client must have called
+   ``PE_UNMASK`` beforehand.
+
+-  Event 0 can't be dispatched.
+
+-  The event must be declared using the ``SDEI_EXPLICIT_EVENT()`` macro
+   described above.
+
+-  The event must be private to the PE.
+
+-  The event must have been registered for and enabled.
+
+-  A dispatch for the same event must not be outstanding. I.e. it hasn't already
+   been dispatched and is yet to be completed.
+
+-  The priority of the event (either Critical or Normal, as configured by the
+   platform at build-time) shouldn't cause priority inversion. This means:
+
+   -  If it's of Normal priority, neither Normal nor Critical priority dispatch
+      must be outstanding on the PE.
+
+   -  If it's of a Critical priority, no Critical priority dispatch must be
+      outstanding on the PE.
+
+Further, the caller should be aware of the following assumptions made by the
+dispatcher:
+
+-  The caller of the API is a component running in EL3; for example, a RAS
+   driver.
+
+-  The requested dispatch will be permitted by the Exception Handling Framework.
+   I.e. the caller must make sure that the requested dispatch has sufficient
+   priority so as not to cause priority level inversion within Exception
+   Handling Framework.
+
+-  The caller must be prepared for the SDEI dispatcher to restore the Non-secure
+   context, and mark that the active context.
+
+-  The call will block until the SDEI client completes the event (i.e. when the
+   client calls either ``SDEI_EVENT_COMPLETE`` or ``SDEI_COMPLETE_AND_RESUME``).
+
+-  The caller must be prepared for this API to return failure and handle
+   accordingly.
+
+Porting requirements
+--------------------
+
+The porting requirements of the SDEI dispatcher are outlined in the
+:ref:`Porting Guide <porting_guide_sdei_requirements>`.
+
+Note on writing SDEI event handlers
+-----------------------------------
+
+*This section pertains to SDEI event handlers in general, not just when using
+the TF-A SDEI dispatcher.*
+
+The SDEI specification requires that event handlers preserve the contents of all
+registers except ``x0`` to ``x17``. This has significance if event handler is
+written in C: compilers typically adjust the stack frame at the beginning and
+end of C functions. For example, AArch64 GCC typically produces the following
+function prologue and epilogue:
+
+::
+
+        c_event_handler:
+                stp     x29, x30, [sp,#-32]!
+                mov     x29, sp
+
+                ...
+
+                bl      ...
+
+                ...
+
+                ldp     x29, x30, [sp],#32
+                ret
+
+The register ``x29`` is used as frame pointer in the prologue. Because neither a
+valid ``SDEI_EVENT_COMPLETE`` nor ``SDEI_EVENT_COMPLETE_AND_RESUME`` calls
+return to the handler, the epilogue never gets executed, and registers ``x29``
+and ``x30`` (in the case above) are inadvertently corrupted. This violates the
+SDEI specification, and the normal execution thereafter will result in
+unexpected behaviour.
+
+To work this around, it's advised that the top-level event handlers are
+implemented in assembly, following a similar pattern as below:
+
+::
+
+        asm_event_handler:
+                /* Save link register whilst maintaining stack alignment */
+                stp     xzr, x30, [sp, #-16]!
+                bl      c_event_handler
+
+                /* Restore link register */
+                ldp     xzr, x30, [sp], #16
+
+                /* Complete call */
+                ldr     x0, =SDEI_EVENT_COMPLETE
+                smc     #0
+                b       .

+Secure Partition Manager (MM)
+*****************************
+
+Foreword
+========
+
+Two implementations of a Secure Partition Manager co-exist in the TF-A codebase:
+
+-  SPM based on the FF-A specification (:ref:`Secure Partition Manager`).
+-  SPM based on the MM interface.
+
+Both implementations differ in their architectures and only one can be selected
+at build time.
+
+This document describes the latter implementation where the Secure Partition Manager
+resides at EL3 and management services run from isolated Secure Partitions at S-EL0.
+The communication protocol is established through the Management Mode (MM) interface.
+
+Background
+==========
+
+In some market segments that primarily deal with client-side devices like mobile
+phones, tablets, STBs and embedded devices, a Trusted OS instantiates trusted
+applications to provide security services like DRM, secure payment and
+authentication. The Global Platform TEE Client API specification defines the API
+used by Non-secure world applications to access these services. A Trusted OS
+fulfils the requirements of a security service as described above.
+
+Management services are typically implemented at the highest level of privilege
+in the system, i.e. EL3 in Trusted Firmware-A (TF-A). The service requirements are
+fulfilled by the execution environment provided by TF-A.
+
+The following diagram illustrates the corresponding software stack:
+
+|Image 1|
+
+In other market segments that primarily deal with server-side devices (e.g. data
+centres and enterprise servers) the secure software stack typically does not
+include a Global Platform Trusted OS. Security functions are accessed through
+other interfaces (e.g. ACPI TCG TPM interface, UEFI runtime variable service).
+
+Placement of management and security functions with diverse requirements in a
+privileged Exception Level (i.e. EL3 or S-EL1) makes security auditing of
+firmware more difficult and does not allow isolation of unrelated services from
+each other either.
+
+Introduction
+============
+
+A **Secure Partition** is a software execution environment instantiated in
+S-EL0 that can be used to implement simple management and security services.
+Since S-EL0 is an unprivileged Exception Level, a Secure Partition relies on
+privileged firmware (i.e. TF-A) to be granted access to system and processor
+resources. Essentially, it is a software sandbox in the Secure world that runs
+under the control of privileged software, provides one or more services and
+accesses the following system resources:
+
+- Memory and device regions in the system address map.
+
+- PE system registers.
+
+- A range of synchronous exceptions (e.g. SMC function identifiers).
+
+Note that currently TF-A only supports handling one Secure Partition.
+
+A Secure Partition enables TF-A to implement only the essential secure
+services in EL3 and instantiate the rest in a partition in S-EL0.
+Furthermore, multiple Secure Partitions can be used to isolate unrelated
+services from each other.
+
+The following diagram illustrates the place of a Secure Partition in a typical
+Armv8-A software stack. A single or multiple Secure Partitions provide secure
+services to software components in the Non-secure world and other Secure
+Partitions.
+
+|Image 2|
+
+The TF-A build system is responsible for including the Secure Partition image
+in the FIP. During boot, BL2 includes support to authenticate and load the
+Secure Partition image. A BL31 component called **Secure Partition Manager
+(SPM)** is responsible for managing the partition. This is semantically
+similar to a hypervisor managing a virtual machine.
+
+The SPM is responsible for the following actions during boot:
+
+- Allocate resources requested by the Secure Partition.
+
+- Perform architectural and system setup required by the Secure Partition to
+  fulfil a service request.
+
+- Implement a standard interface that is used for initialising a Secure
+  Partition.
+
+The SPM is responsible for the following actions during runtime:
+
+- Implement a standard interface that is used by a Secure Partition to fulfil
+  service requests.
+
+- Implement a standard interface that is used by the Non-secure world for
+  accessing the services exported by a Secure Partition. A service can be
+  invoked through a SMC.
+
+Alternatively, a partition can be viewed as a thread of execution running under
+the control of the SPM. Hence common programming concepts described below are
+applicable to a partition.
+
+Description
+===========
+
+The previous section introduced some general aspects of the software
+architecture of a Secure Partition. This section describes the specific choices
+made in the current implementation of this software architecture. Subsequent
+revisions of the implementation will include a richer set of features that
+enable a more flexible architecture.
+
+Building TF-A with Secure Partition support
+-------------------------------------------
+
+SPM is supported on the Arm FVP exclusively at the moment. The current
+implementation supports inclusion of only a single Secure Partition in which a
+service always runs to completion (e.g. the requested services cannot be
+preempted to give control back to the Normal world).
+
+It is not currently possible for BL31 to integrate SPM support and a Secure
+Payload Dispatcher (SPD) at the same time; they are mutually exclusive. In the
+SPM bootflow, a Secure Partition image executing at S-EL0 replaces the Secure
+Payload image executing at S-EL1 (e.g. a Trusted OS). Both are referred to as
+BL32.
+
+A working prototype of a SP has been implemented by re-purposing the EDK2 code
+and tools, leveraging the concept of the *Standalone Management Mode (MM)* in
+the UEFI specification (see the PI v1.6 Volume 4: Management Mode Core
+Interface). This will be referred to as the *Standalone MM Secure Partition* in
+the rest of this document.
+
+To enable SPM support in TF-A, the source code must be compiled with the build
+flag ``SPM_MM=1``, along with ``EL3_EXCEPTION_HANDLING=1`` and ``ENABLE_SVE_FOR_NS=0``.
+On Arm platforms the build option ``ARM_BL31_IN_DRAM`` must be set to 1. Also, the
+location of the binary that contains the BL32 image
+(``BL32=path/to/image.bin``) must be specified.
+
+First, build the Standalone MM Secure Partition. To build it, refer to the
+`instructions in the EDK2 repository`_.
+
+Then build TF-A with SPM support and include the Standalone MM Secure Partition
+image in the FIP:
+
+.. code:: shell
+
+    BL32=path/to/standalone/mm/sp BL33=path/to/bl33.bin \
+    make PLAT=fvp SPM_MM=1 EL3_EXCEPTION_HANDLING=1 ENABLE_SVE_FOR_NS=0 ARM_BL31_IN_DRAM=1 all fip
+
+Describing Secure Partition resources
+-------------------------------------
+
+TF-A exports a porting interface that enables a platform to specify the system
+resources required by the Secure Partition. Some instructions are given below.
+However, this interface is under development and it may change as new features
+are implemented.
+
+- A Secure Partition is considered a BL32 image, so the same defines that apply
+  to BL32 images apply to a Secure Partition: ``BL32_BASE`` and ``BL32_LIMIT``.
+
+- The following defines are needed to allocate space for the translation tables
+  used by the Secure Partition: ``PLAT_SP_IMAGE_MMAP_REGIONS`` and
+  ``PLAT_SP_IMAGE_MAX_XLAT_TABLES``.
+
+- The functions ``plat_get_secure_partition_mmap()`` and
+  ``plat_get_secure_partition_boot_info()`` have to be implemented. The file
+  ``plat/arm/board/fvp/fvp_common.c`` can be used as an example. It uses the
+  defines in ``include/plat/arm/common/arm_spm_def.h``.
+
+  - ``plat_get_secure_partition_mmap()`` returns an array of mmap regions that
+    describe the memory regions that the SPM needs to allocate for a Secure
+    Partition.
+
+  - ``plat_get_secure_partition_boot_info()`` returns a
+    ``spm_mm_boot_info_t`` struct that is populated by the platform
+    with information about the memory map of the Secure Partition.
+
+For an example of all the changes in context, you may refer to commit
+``e29efeb1b4``, in which the port for FVP was introduced.
+
+Accessing Secure Partition services
+-----------------------------------
+
+The `SMC Calling Convention`_ (*Arm DEN 0028B*) describes SMCs as a conduit for
+accessing services implemented in the Secure world. The ``MM_COMMUNICATE``
+interface defined in the `Management Mode Interface Specification`_ (*Arm DEN
+0060A*) is used to invoke a Secure Partition service as a Fast Call.
+
+The mechanism used to identify a service within the partition depends on the
+service implementation. It is assumed that the caller of the service will be
+able to discover this mechanism through standard platform discovery mechanisms
+like ACPI and Device Trees. For example, *Volume 4: Platform Initialisation
+Specification v1.6. Management Mode Core Interface* specifies that a GUID is
+used to identify a management mode service. A client populates the GUID in the
+``EFI_MM_COMMUNICATE_HEADER``. The header is populated in the communication
+buffer shared with the Secure Partition.
+
+A Fast Call appears to be atomic from the perspective of the caller and returns
+when the requested operation has completed. A service invoked through the
+``MM_COMMUNICATE`` SMC will run to completion in the partition on a given CPU.
+The SPM is responsible for guaranteeing this behaviour. This means that there
+can only be a single outstanding Fast Call in a partition on a given CPU.
+
+Exchanging data with the Secure Partition
+-----------------------------------------
+
+The exchange of data between the Non-secure world and the partition takes place
+through a shared memory region. The location of data in the shared memory area
+is passed as a parameter to the ``MM_COMMUNICATE`` SMC. The shared memory area
+is statically allocated by the SPM and is expected to be either implicitly known
+to the Non-secure world or discovered through a platform discovery mechanism
+e.g. ACPI table or device tree. It is possible for the Non-secure world to
+exchange data with a partition only if it has been populated in this shared
+memory area. The shared memory area is implemented as per the guidelines
+specified in Section 3.2.3 of the `Management Mode Interface Specification`_
+(*Arm DEN 0060A*).
+
+The format of data structures used to encapsulate data in the shared memory is
+agreed between the Non-secure world and the Secure Partition. For example, in
+the `Management Mode Interface specification`_ (*Arm DEN 0060A*), Section 4
+describes that the communication buffer shared between the Non-secure world and
+the Management Mode (MM) in the Secure world must be of the type
+``EFI_MM_COMMUNICATE_HEADER``. This data structure is defined in *Volume 4:
+Platform Initialisation Specification v1.6. Management Mode Core Interface*.
+Any caller of a MM service will have to use the ``EFI_MM_COMMUNICATE_HEADER``
+data structure.
+
+Runtime model of the Secure Partition
+=====================================
+
+This section describes how the Secure Partition interfaces with the SPM.
+
+Interface with SPM
+------------------
+
+In order to instantiate one or more secure services in the Secure Partition in
+S-EL0, the SPM should define the following types of interfaces:
+
+- Interfaces that enable access to privileged operations from S-EL0. These
+  operations typically require access to system resources that are either shared
+  amongst multiple software components in the Secure world or cannot be directly
+  accessed from an unprivileged Exception Level.
+
+- Interfaces that establish the control path between the SPM and the Secure
+  Partition.
+
+This section describes the APIs currently exported by the SPM that enable a
+Secure Partition to initialise itself and export its services in S-EL0. These
+interfaces are not accessible from the Non-secure world.
+
+Conduit
+^^^^^^^
+
+The `SMC Calling Convention`_ (*Arm DEN 0028B*) specification describes the SMC
+and HVC conduits for accessing firmware services and their availability
+depending on the implemented Exception levels. In S-EL0, the Supervisor Call
+exception (SVC) is the only architectural mechanism available for unprivileged
+software to make a request for an operation implemented in privileged software.
+Hence, the SVC conduit must be used by the Secure Partition to access interfaces
+implemented by the SPM.
+
+A SVC causes an exception to be taken to S-EL1. TF-A assumes ownership of S-EL1
+and installs a simple exception vector table in S-EL1 that relays a SVC request
+from a Secure Partition as a SMC request to the SPM in EL3. Upon servicing the
+SMC request, Trusted Firmware-A returns control directly to S-EL0 through an
+ERET instruction.
+
+Calling conventions
+^^^^^^^^^^^^^^^^^^^
+
+The `SMC Calling Convention`_ (*Arm DEN 0028B*) specification describes the
+32-bit and 64-bit calling conventions for the SMC and HVC conduits. The SVC
+conduit introduces the concept of SVC32 and SVC64 calling conventions. The SVC32
+and SVC64 calling conventions are equivalent to the 32-bit (SMC32) and the
+64-bit (SMC64) calling conventions respectively.
+
+Communication initiated by SPM
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+A service request is initiated from the SPM through an exception return
+instruction (ERET) to S-EL0. Later, the Secure Partition issues an SVC
+instruction to signal completion of the request. Some example use cases are
+given below:
+
+- A request to initialise the Secure Partition during system boot.
+
+- A request to handle a runtime service request.
+
+Communication initiated by Secure Partition
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+A request is initiated from the Secure Partition by executing a SVC instruction.
+An ERET instruction is used by TF-A to return to S-EL0 with the result of the
+request.
+
+For instance, a request to perform privileged operations on behalf of a
+partition (e.g.  management of memory attributes in the translation tables for
+the Secure EL1&0 translation regime).
+
+Interfaces
+^^^^^^^^^^
+
+The current implementation reserves function IDs for Fast Calls in the Standard
+Secure Service calls range (see `SMC Calling Convention`_ (*Arm DEN 0028B*)
+specification) for each API exported by the SPM. This section defines the
+function prototypes for each function ID. The function IDs specify whether one
+or both of the SVC32 and SVC64 calling conventions can be used to invoke the
+corresponding interface.
+
+Secure Partition Event Management
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The Secure Partition provides an Event Management interface that is used by the
+SPM to delegate service requests to the Secure Partition. The interface also
+allows the Secure Partition to:
+
+- Register with the SPM a service that it provides.
+- Indicate completion of a service request delegated by the SPM
+
+Miscellaneous interfaces
+------------------------
+
+``SPM_MM_VERSION_AARCH32``
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+- Description
+
+  Returns the version of the interface exported by SPM.
+
+- Parameters
+
+  - **uint32** - Function ID
+
+    - SVC32 Version: **0x84000060**
+
+- Return parameters
+
+  - **int32** - Status
+
+    On success, the format of the value is as follows:
+
+    - Bit [31]: Must be 0
+    - Bits [30:16]: Major Version. Must be 0 for this revision of the SPM
+      interface.
+    - Bits [15:0]: Minor Version. Must be 1 for this revision of the SPM
+      interface.
+
+    On error, the format of the value is as follows:
+
+    - ``NOT_SUPPORTED``: SPM interface is not supported or not available for the
+      client.
+
+- Usage
+
+  This function returns the version of the Secure Partition Manager
+  implementation. The major version is 0 and the minor version is 1. The version
+  number is a 31-bit unsigned integer, with the upper 15 bits denoting the major
+  revision, and the lower 16 bits denoting the minor revision. The following
+  rules apply to the version numbering:
+
+  - Different major revision values indicate possibly incompatible functions.
+
+  - For two revisions, A and B, for which the major revision values are
+    identical, if the minor revision value of revision B is greater than the
+    minor revision value of revision A, then every function in revision A must
+    work in a compatible way with revision B. However, it is possible for
+    revision B to have a higher function count than revision A.
+
+- Implementation responsibilities
+
+  If this function returns a valid version number, all the functions that are
+  described subsequently must be implemented, unless it is explicitly stated
+  that a function is optional.
+
+See `Error Codes`_ for integer values that are associated with each return
+code.
+
+Secure Partition Initialisation
+-------------------------------
+
+The SPM is responsible for initialising the architectural execution context to
+enable initialisation of a service in S-EL0. The responsibilities of the SPM are
+listed below. At the end of initialisation, the partition issues a
+``MM_SP_EVENT_COMPLETE_AARCH64`` call (described later) to signal readiness for
+handling requests for services implemented by the Secure Partition. The
+initialisation event is executed as a Fast Call.
+
+Entry point invocation
+^^^^^^^^^^^^^^^^^^^^^^
+
+The entry point for service requests that should be handled as Fast Calls is
+used as the target of the ERET instruction to start initialisation of the Secure
+Partition.
+
+Architectural Setup
+^^^^^^^^^^^^^^^^^^^
+
+At cold boot, system registers accessible from S-EL0 will be in their reset
+state unless otherwise specified. The SPM will perform the following
+architectural setup to enable execution in S-EL0
+
+MMU setup
+^^^^^^^^^
+
+The platform port of a Secure Partition specifies to the SPM a list of regions
+that it needs access to and their attributes. The SPM validates this resource
+description and initialises the Secure EL1&0 translation regime as follows.
+
+1. Device regions are mapped with nGnRE attributes and Execute Never
+   instruction access permissions.
+
+2. Code memory regions are mapped with RO data and Executable instruction access
+   permissions.
+
+3. Read Only data memory regions are mapped with RO data and Execute Never
+   instruction access permissions.
+
+4. Read Write data memory regions are mapped with RW data and Execute Never
+   instruction access permissions.
+
+5. If the resource description does not explicitly describe the type of memory
+   regions then all memory regions will be marked with Code memory region
+   attributes.
+
+6. The ``UXN`` and ``PXN`` bits are set for regions that are not executable by
+   S-EL0 or S-EL1.
+
+System Register Setup
+^^^^^^^^^^^^^^^^^^^^^
+
+System registers that influence software execution in S-EL0 are setup by the SPM
+as follows:
+
+1. ``SCTLR_EL1``
+
+   - ``UCI=1``
+   - ``EOE=0``
+   - ``WXN=1``
+   - ``nTWE=1``
+   - ``nTWI=1``
+   - ``UCT=1``
+   - ``DZE=1``
+   - ``I=1``
+   - ``UMA=0``
+   - ``SA0=1``
+   - ``C=1``
+   - ``A=1``
+   - ``M=1``
+
+2. ``CPACR_EL1``
+
+   - ``FPEN=b'11``
+
+3. ``PSTATE``
+
+   - ``D,A,I,F=1``
+   - ``CurrentEL=0`` (EL0)
+   - ``SpSel=0`` (Thread mode)
+   - ``NRW=0`` (AArch64)
+
+General Purpose Register Setup
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+SPM will invoke the entry point of a service by executing an ERET instruction.
+This transition into S-EL0 is special since it is not in response to a previous
+request through a SVC instruction. This is the first entry into S-EL0. The
+general purpose register usage at the time of entry will be as specified in the
+"Return State" column of Table 3-1 in Section 3.1 "Register use in AArch64 SMC
+calls" of the `SMC Calling Convention`_ (*Arm DEN 0028B*) specification. In
+addition, certain other restrictions will be applied as described below.
+
+1. ``SP_EL0``
+
+   A non-zero value will indicate that the SPM has initialised the stack pointer
+   for the current CPU.
+
+   The value will be 0 otherwise.
+
+2. ``X4-X30``
+
+   The values of these registers will be 0.
+
+3. ``X0-X3``
+
+   Parameters passed by the SPM.
+
+   - ``X0``: Virtual address of a buffer shared between EL3 and S-EL0. The
+     buffer will be mapped in the Secure EL1&0 translation regime with read-only
+     memory attributes described earlier.
+
+   - ``X1``: Size of the buffer in bytes.
+
+   - ``X2``: Cookie value (*IMPLEMENTATION DEFINED*).
+
+   - ``X3``: Cookie value (*IMPLEMENTATION DEFINED*).
+
+Runtime Event Delegation
+------------------------
+
+The SPM receives requests for Secure Partition services through a synchronous
+invocation (i.e. a SMC from the Non-secure world). These requests are delegated
+to the partition by programming a return from the last
+``MM_SP_EVENT_COMPLETE_AARCH64`` call received from the partition. The last call
+was made to signal either completion of Secure Partition initialisation or
+completion of a partition service request.
+
+``MM_SP_EVENT_COMPLETE_AARCH64``
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+- Description
+
+  Signal completion of the last SP service request.
+
+- Parameters
+
+  - **uint32** - Function ID
+
+    - SVC64 Version: **0xC4000061**
+
+  - **int32** - Event Status Code
+
+    Zero or a positive value indicates that the event was handled successfully.
+    The values depend upon the original event that was delegated to the Secure
+    partition. They are described as follows.
+
+    - ``SUCCESS`` : Used to indicate that the Secure Partition was initialised
+      or a runtime request was handled successfully.
+
+    - Any other value greater than 0 is used to pass a specific Event Status
+      code in response to a runtime event.
+
+    A negative value indicates an error. The values of Event Status code depend
+    on the original event.
+
+- Return parameters
+
+  - **int32** - Event ID/Return Code
+
+    Zero or a positive value specifies the unique ID of the event being
+    delegated to the partition by the SPM.
+
+    In the current implementation, this parameter contains the function ID of
+    the ``MM_COMMUNICATE`` SMC. This value indicates to the partition that an
+    event has been delegated to it in response to an ``MM_COMMUNICATE`` request
+    from the Non-secure world.
+
+    A negative value indicates an error. The format of the value is as follows:
+
+    - ``NOT_SUPPORTED``: Function was called from the Non-secure world.
+
+    See `Error Codes`_ for integer values that are associated with each return
+    code.
+
+  - **uint32** - Event Context Address
+
+    Address of a buffer shared between the SPM and Secure Partition to pass
+    event specific information. The format of the data populated in the buffer
+    is implementation defined.
+
+    The buffer is mapped in the Secure EL1&0 translation regime with read-only
+    memory attributes described earlier.
+
+    For the SVC64 version, this parameter is a 64-bit Virtual Address (VA).
+
+    For the SVC32 version, this parameter is a 32-bit Virtual Address (VA).
+
+  - **uint32** - Event context size
+
+    Size of the memory starting at Event Address.
+
+  - **uint32/uint64** - Event Cookie
+
+    This is an optional parameter. If unused its value is SBZ.
+
+- Usage
+
+  This function signals to the SPM that the handling of the last event delegated
+  to a partition has completed. The partition is ready to handle its next event.
+  A return from this function is in response to the next event that will be
+  delegated to the partition. The return parameters describe the next event.
+
+- Caller responsibilities
+
+  A Secure Partition must only call ``MM_SP_EVENT_COMPLETE_AARCH64`` to signal
+  completion of a request that was delegated to it by the SPM.
+
+- Callee responsibilities
+
+  When the SPM receives this call from a Secure Partition, the corresponding
+  syndrome information can be used to return control through an ERET
+  instruction, to the instruction immediately after the call in the Secure
+  Partition context. This syndrome information comprises of general purpose and
+  system register values when the call was made.
+
+  The SPM must save this syndrome information and use it to delegate the next
+  event to the Secure Partition. The return parameters of this interface must
+  specify the properties of the event and be populated in ``X0-X3/W0-W3``
+  registers.
+
+Secure Partition Memory Management
+----------------------------------
+
+A Secure Partition executes at S-EL0, which is an unprivileged Exception Level.
+The SPM is responsible for enabling access to regions of memory in the system
+address map from a Secure Partition. This is done by mapping these regions in
+the Secure EL1&0 Translation regime with appropriate memory attributes.
+Attributes refer to memory type, permission, cacheability and shareability
+attributes used in the Translation tables. The definitions of these attributes
+and their usage can be found in the `Armv8-A ARM`_ (*Arm DDI 0487*).
+
+All memory required by the Secure Partition is allocated upfront in the SPM,
+even before handing over to the Secure Partition for the first time. The initial
+access permissions of the memory regions are statically provided by the platform
+port and should allow the Secure Partition to run its initialisation code.
+
+However, they might not suit the final needs of the Secure Partition because its
+final memory layout might not be known until the Secure Partition initialises
+itself. As the Secure Partition initialises its runtime environment it might,
+for example, load dynamically some modules. For instance, a Secure Partition
+could implement a loader for a standard executable file format (e.g. an PE-COFF
+loader for loading executable files at runtime). These executable files will be
+a part of the Secure Partition image. The location of various sections in an
+executable file and their permission attributes (e.g. read-write data, read-only
+data and code) will be known only when the file is loaded into memory.
+
+In this case, the Secure Partition needs a way to change the access permissions
+of its memory regions. The SPM provides this feature through the
+``MM_SP_MEMORY_ATTRIBUTES_SET_AARCH64`` SVC interface. This interface is
+available to the Secure Partition during a specific time window: from the first
+entry into the Secure Partition up to the first ``SP_EVENT_COMPLETE`` call that
+signals the Secure Partition has finished its initialisation. Once the
+initialisation is complete, the SPM does not allow changes to the memory
+attributes.
+
+This section describes the standard SVC interface that is implemented by the SPM
+to determine and change permission attributes of memory regions that belong to a
+Secure Partition.
+
+``MM_SP_MEMORY_ATTRIBUTES_GET_AARCH64``
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+- Description
+
+  Request the permission attributes of a memory region from S-EL0.
+
+- Parameters
+
+  - **uint32** Function ID
+
+    - SVC64 Version: **0xC4000064**
+
+  - **uint64** Base Address
+
+    This parameter is a 64-bit Virtual Address (VA).
+
+    There are no alignment restrictions on the Base Address. The permission
+    attributes of the translation granule it lies in are returned.
+
+- Return parameters
+
+  - **int32** - Memory Attributes/Return Code
+
+    On success the format of the Return Code is as follows:
+
+    - Bits[1:0] : Data access permission
+
+      - b'00 : No access
+      - b'01 : Read-Write access
+      - b'10 : Reserved
+      - b'11 : Read-only access

+
+      - b'0 : Executable
+      - b'1 : Non-executable
+
+    - Bit[30:3] : Reserved. SBZ.
+
+    - Bit[31]   : Must be 0
+
+    On failure the following error codes are returned:
+
+    - ``INVALID_PARAMETERS``: The Secure Partition is not allowed to access the
+      memory region the Base Address lies in.
+
+    - ``NOT_SUPPORTED`` : The SPM does not support retrieval of attributes of
+      any memory page that is accessible by the Secure Partition, or the
+      function was called from the Non-secure world. Also returned if it is
+      used after ``MM_SP_EVENT_COMPLETE_AARCH64``.
+
+    See `Error Codes`_ for integer values that are associated with each return
+    code.
+
+- Usage
+
+  This function is used to request the permission attributes for S-EL0 on a
+  memory region accessible from a Secure Partition. The size of the memory
+  region is equal to the Translation Granule size used in the Secure EL1&0
+  translation regime. Requests to retrieve other memory region attributes are
+  not currently supported.
+
+- Caller responsibilities
+
+  The caller must obtain the Translation Granule Size of the Secure EL1&0
+  translation regime from the SPM through an implementation defined method.
+
+- Callee responsibilities
+
+  The SPM must not return the memory access controls for a page of memory that
+  is not accessible from a Secure Partition.
+
+``MM_SP_MEMORY_ATTRIBUTES_SET_AARCH64``
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+- Description
+
+  Set the permission attributes of a memory region from S-EL0.
+
+- Parameters
+
+  - **uint32** - Function ID
+
+    - SVC64 Version: **0xC4000065**
+
+  - **uint64** - Base Address
+
+    This parameter is a 64-bit Virtual Address (VA).
+
+    The alignment of the Base Address must be greater than or equal to the size
+    of the Translation Granule Size used in the Secure EL1&0 translation
+    regime.
+
+  - **uint32** - Page count
+
+    Number of pages starting from the Base Address whose memory attributes
+    should be changed. The page size is equal to the Translation Granule Size.

+
+    - Bits[31:3] : Reserved. SBZ.
+
+    A combination of attributes that mark the region with RW and Executable
+    permissions is prohibited. A request to mark a device memory region with
+    Executable permissions is prohibited.
+
+- Return parameters
+
+  - **int32** - Return Code
+
+    - ``SUCCESS``: The Memory Access Controls were changed successfully.
+
+    - ``DENIED``: The SPM is servicing a request to change the attributes of a
+      memory region that overlaps with the region specified in this request.
+
+    - ``INVALID_PARAMETER``: An invalid combination of Memory Access Controls
+      has been specified. The Base Address is not correctly aligned. The Secure
+      Partition is not allowed to access part or all of the memory region
+      specified in the call.
+
+    - ``NO_MEMORY``: The SPM does not have memory resources to change the
+      attributes of the memory region in the translation tables.
+
+    - ``NOT_SUPPORTED``: The SPM does not permit change of attributes of any
+      memory region that is accessible by the Secure Partition. Function was
+      called from the Non-secure world. Also returned if it is used after
+      ``MM_SP_EVENT_COMPLETE_AARCH64``.
+
+    See `Error Codes`_ for integer values that are associated with each return
+    code.
+
+- Usage
+
+  This function is used to change the permission attributes for S-EL0 on a
+  memory region accessible from a Secure Partition. The size of the memory
+  region is equal to the Translation Granule size used in the Secure EL1&0
+  translation regime. Requests to change other memory region attributes are not
+  currently supported.
+
+  This function is only available at boot time. This interface is revoked after
+  the Secure Partition sends the first ``MM_SP_EVENT_COMPLETE_AARCH64`` to
+  signal that it is initialised and ready to receive run-time requests.
+
+- Caller responsibilities
+
+  The caller must obtain the Translation Granule Size of the Secure EL1&0
+  translation regime from the SPM through an implementation defined method.
+
+- Callee responsibilities
+
+  The SPM must preserve the original memory access controls of the region of
+  memory in case of an unsuccessful call.  The SPM must preserve the consistency
+  of the S-EL1 translation regime if this function is called on different PEs
+  concurrently and the memory regions specified overlap.

+Foreword
+========
+
+Three implementations of a Secure Partition Manager co-exist in the TF-A
+codebase:
+
+#. S-EL2 SPMC based on the FF-A specification `[1]`_, enabling virtualization in
+   the secure world, managing multiple S-EL1 or S-EL0 partitions.
+#. EL3 SPMC based on the FF-A specification, managing a single S-EL1 partition
+   without virtualization in the secure world.
+#. EL3 SPM based on the MM specification, legacy implementation managing a
+   single S-EL0 partition `[2]`_.
+
+These implementations differ in their respective SW architecture and only one
+can be selected at build time. This document:
+
+- describes the implementation from bullet 1. when the SPMC resides at S-EL2.
+- is not an architecture specification and it might provide assumptions
+  on sections mandated as implementation-defined in the specification.
+- covers the implications to TF-A used as a bootloader, and Hafnium used as a
+  reference code base for an S-EL2/SPMC secure firmware on platforms
+  implementing the FEAT_SEL2 architecture extension.
+
+Terminology
+-----------
+
+- The term Hypervisor refers to the NS-EL2 component managing Virtual Machines
+  (or partitions) in the normal world.
+- The term SPMC refers to the S-EL2 component managing secure partitions in
+  the secure world when the FEAT_SEL2 architecture extension is implemented.
+- Alternatively, SPMC can refer to an S-EL1 component, itself being a secure
+  partition and implementing the FF-A ABI on platforms not implementing the
+  FEAT_SEL2 architecture extension.
+- The term VM refers to a normal world Virtual Machine managed by an Hypervisor.
+- The term SP refers to a secure world "Virtual Machine" managed by an SPMC.
+
+Support for legacy platforms
+----------------------------
+
+The SPM is split into a dispatcher and a core component (respectively SPMD and
+SPMC) residing at different exception levels. To permit the FF-A specification
+adoption and a smooth migration, the SPMD supports an SPMC residing either at
+S-EL1 or S-EL2:
+
+- The SPMD is located at EL3 and mainly relays the FF-A protocol from NWd
+  (Hypervisor or OS kernel) to the SPMC.
+- The same SPMD component is used for both S-EL1 and S-EL2 SPMC configurations.
+- The SPMC exception level is a build time choice.
+
+TF-A supports both cases:
+
+- S-EL1 SPMC for platforms not supporting the FEAT_SEL2 architecture
+  extension. The SPMD relays the FF-A protocol from EL3 to S-EL1.
+- S-EL2 SPMC for platforms implementing the FEAT_SEL2 architecture
+  extension. The SPMD relays the FF-A protocol from EL3 to S-EL2.
+
+Sample reference stack
+======================
+
+The following diagram illustrates a possible configuration when the
+FEAT_SEL2 architecture extension is implemented, showing the SPMD
+and SPMC, one or multiple secure partitions, with an optional
+Hypervisor:
+
+.. image:: ../resources/diagrams/ff-a-spm-sel2.png
+
+TF-A build options
+==================
+
+This section explains the TF-A build options involved in building with
+support for an FF-A based SPM where the SPMD is located at EL3 and the
+SPMC located at S-EL1, S-EL2 or EL3:
+
+- **SPD=spmd**: this option selects the SPMD component to relay the FF-A
+  protocol from NWd to SWd back and forth. It is not possible to
+  enable another Secure Payload Dispatcher when this option is chosen.
+- **SPMD_SPM_AT_SEL2**: this option adjusts the SPMC exception
+  level to being at S-EL2. It defaults to enabled (value 1) when
+  SPD=spmd is chosen.
+- **SPMC_AT_EL3**: this option adjusts the SPMC exception level to being
+  at EL3.
+- If neither ``SPMD_SPM_AT_SEL2`` or ``SPMC_AT_EL3`` are enabled the SPMC
+  exception level is set to S-EL1.
+- **CTX_INCLUDE_EL2_REGS**: this option permits saving (resp.
+  restoring) the EL2 system register context before entering (resp.
+  after leaving) the SPMC. It is mandatorily enabled when
+  ``SPMD_SPM_AT_SEL2`` is enabled. The context save/restore routine
+  and exhaustive list of registers is visible at `[4]`_.
+- **SP_LAYOUT_FILE**: this option specifies a text description file
+  providing paths to SP binary images and manifests in DTS format
+  (see `Describing secure partitions`_). It
+  is required when ``SPMD_SPM_AT_SEL2`` is enabled hence when multiple
+  secure partitions are to be loaded by BL2 on behalf of the SPMC.

+Other combinations of such build options either break the build or are not
+supported.
+
+Notes:
+
+- Only Arm's FVP platform is supported to use with the TF-A reference software
+  stack.
+- When ``SPMD_SPM_AT_SEL2=1``, the reference software stack assumes enablement
+  of FEAT_PAuth, FEAT_BTI and FEAT_MTE architecture extensions.
+- The ``CTX_INCLUDE_EL2_REGS`` option provides the generic support for
+  barely saving/restoring EL2 registers from an Arm arch perspective. As such
+  it is decoupled from the ``SPD=spmd`` option.
+- BL32 option is re-purposed to specify the SPMC image. It can specify either
+  the Hafnium binary path (built for the secure world) or the path to a TEE
+  binary implementing FF-A interfaces.
+- BL33 option can specify the TFTF binary or a normal world loader
+  such as U-Boot or the UEFI framework payload.

+Boot process
+============
+
+Loading Hafnium and secure partitions in the secure world
+---------------------------------------------------------
+
+TF-A BL2 is the bootlader for the SPMC and SPs in the secure world.
+
+SPs may be signed by different parties (SiP, OEM/ODM, TOS vendor, etc.).
+Thus they are supplied as distinct signed entities within the FIP flash
+image. The FIP image itself is not signed hence this provides the ability
+to upgrade SPs in the field.
+
+Booting through TF-A
+--------------------
+
+SP manifests
+~~~~~~~~~~~~
+
+An SP manifest describes SP attributes as defined in `[1]`_
+(partition manifest at virtual FF-A instance) in DTS format. It is
+represented as a single file associated with the SP. A sample is
+provided by `[5]`_. A binding document is provided by `[6]`_.
+
+Secure Partition packages
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Secure partitions are bundled as independent package files consisting
+of:
+
+- a header
+- a DTB
+- an image payload
+
+The header starts with a magic value and offset values to SP DTB and
+image payload. Each SP package is loaded independently by BL2 loader
+and verified for authenticity and integrity.
+
+The SP package identified by its UUID (matching FF-A uuid property) is
+inserted as a single entry into the FIP at end of the TF-A build flow
+as shown:
+
+.. code:: shell
+
+    Trusted Boot Firmware BL2: offset=0x1F0, size=0x8AE1, cmdline="--tb-fw"
+    EL3 Runtime Firmware BL31: offset=0x8CD1, size=0x13000, cmdline="--soc-fw"
+    Secure Payload BL32 (Trusted OS): offset=0x1BCD1, size=0x15270, cmdline="--tos-fw"
+    Non-Trusted Firmware BL33: offset=0x30F41, size=0x92E0, cmdline="--nt-fw"
+    HW_CONFIG: offset=0x3A221, size=0x2348, cmdline="--hw-config"
+    TB_FW_CONFIG: offset=0x3C569, size=0x37A, cmdline="--tb-fw-config"
+    SOC_FW_CONFIG: offset=0x3C8E3, size=0x48, cmdline="--soc-fw-config"
+    TOS_FW_CONFIG: offset=0x3C92B, size=0x427, cmdline="--tos-fw-config"
+    NT_FW_CONFIG: offset=0x3CD52, size=0x48, cmdline="--nt-fw-config"
+    B4B5671E-4A90-4FE1-B81F-FB13DAE1DACB: offset=0x3CD9A, size=0xC168, cmdline="--blob"
+    D1582309-F023-47B9-827C-4464F5578FC8: offset=0x48F02, size=0xC168, cmdline="--blob"
+
+.. uml:: ../resources/diagrams/plantuml/fip-secure-partitions.puml
+
+Describing secure partitions
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+A json-formatted description file is passed to the build flow specifying paths
+to the SP binary image and associated DTS partition manifest file. The latter
+is processed by the dtc compiler to generate a DTB fed into the SP package.
+Optionally, the partition's json description can contain offsets for both
+the image and partition manifest within the SP package. Both offsets need to be
+4KB aligned, because it is the translation granule supported by Hafnium SPMC.
+These fields can be leveraged to support SPs with S1 translation granules that
+differ from 4KB, and to configure the regions allocated within the SP package,
+as well as to comply with the requirements for the implementation of the boot
+information protocol (see `Passing boot data to the SP`_ for more details). In
+case the offsets are absent in their json node, they default to 0x1000 and
+0x4000 for the manifest offset and image offset respectively.
+This file also specifies the SP owner (as an optional field) identifying the
+signing domain in case of dual root CoT.
+The SP owner can either be the silicon or the platform provider. The
+corresponding "owner" field value can either take the value of "SiP" or "Plat".
+In absence of "owner" field, it defaults to "SiP" owner.
+The UUID of the partition can be specified as a field in the description file or
+if it does not exist there the UUID is extracted from the DTS partition
+manifest.
+
+.. code:: shell
+
+    {
+        "tee1" : {
+            "image": "tee1.bin",
+             "pm": "tee1.dts",
+             "owner": "SiP",
+             "uuid": "1b1820fe-48f7-4175-8999-d51da00b7c9f"
+        },
+
+        "tee2" : {
+            "image": "tee2.bin",
+            "pm": "tee2.dts",
+            "owner": "Plat"
+        },
+
+        "tee3" : {
+            "image": {
+                "file": "tee3.bin",
+                "offset":"0x2000"
+             },
+            "pm": {
+                "file": "tee3.dts",
+                "offset":"0x6000"
+             },
+            "owner": "Plat"
+        },
+    }
+
+SPMC manifest
+~~~~~~~~~~~~~
+
+This manifest contains the SPMC *attribute* node consumed by the SPMD at boot
+time. It implements `[1]`_ (SP manifest at physical FF-A instance) and serves
+two different cases:
+
+- The SPMC resides at S-EL1: the SPMC manifest is used by the SPMD to setup a
+  SP that co-resides with the SPMC and executes at S-EL1 or Secure Supervisor
+  mode.
+- The SPMC resides at S-EL2: the SPMC manifest is used by the SPMD to setup
+  the environment required by the SPMC to run at S-EL2. SPs run at S-EL1 or
+  S-EL0.
+
+.. code:: shell
+
+    attribute {
+        spmc_id = <0x8000>;
+        maj_ver = <0x1>;
+        min_ver = <0x1>;
+        exec_state = <0x0>;
+        load_address = <0x0 0x6000000>;
+        entrypoint = <0x0 0x6000000>;
+        binary_size = <0x60000>;
+    };
+
+- *spmc_id* defines the endpoint ID value that SPMC can query through
+  ``FFA_ID_GET``.
+- *maj_ver/min_ver*. SPMD checks provided version versus its internal
+  version and aborts if not matching.
+- *exec_state* defines the SPMC execution state (AArch64 or AArch32).
+  Notice Hafnium used as a SPMC only supports AArch64.
+- *load_address* and *binary_size* are mostly used to verify secondary
+  entry points fit into the loaded binary image.
+- *entrypoint* defines the cold boot primary core entry point used by
+  SPMD (currently matches ``BL32_BASE``) to enter the SPMC.
+
+Other nodes in the manifest are consumed by Hafnium in the secure world.
+A sample can be found at `[7]`_:
+
+- The *hypervisor* node describes SPs. *is_ffa_partition* boolean attribute
+  indicates a FF-A compliant SP. The *load_address* field specifies the load
+  address at which BL2 loaded the SP package.
+- *cpus* node provide the platform topology and allows MPIDR to VMPIDR mapping.
+  Note the primary core is declared first, then secondary cores are declared
+  in reverse order.
+- The *memory* node provides platform information on the ranges of memory
+  available to the SPMC.
+
+SPMC boot
+~~~~~~~~~
+
+The SPMC is loaded by BL2 as the BL32 image.
+
+The SPMC manifest is loaded by BL2 as the ``TOS_FW_CONFIG`` image `[9]`_.
+
+BL2 passes the SPMC manifest address to BL31 through a register.
+
+At boot time, the SPMD in BL31 runs from the primary core, initializes the core
+contexts and launches the SPMC (BL32) passing the following information through
+registers:
+
+- X0 holds the ``TOS_FW_CONFIG`` physical address (or SPMC manifest blob).
+- X1 holds the ``HW_CONFIG`` physical address.
+- X4 holds the currently running core linear id.
+
+Loading of SPs
+~~~~~~~~~~~~~~
+
+At boot time, BL2 loads SPs sequentially in addition to the SPMC as depicted
+below:
+
+.. uml:: ../resources/diagrams/plantuml/bl2-loading-sp.puml
+
+Note this boot flow is an implementation sample on Arm's FVP platform.
+Platforms not using TF-A's *Firmware CONFiguration* framework would adjust to a
+different boot flow. The flow restricts to a maximum of 8 secure partitions.
+
+Secure boot
+~~~~~~~~~~~
+
+The SP content certificate is inserted as a separate FIP item so that BL2 loads SPMC,
+SPMC manifest, secure partitions and verifies them for authenticity and integrity.
+Refer to TBBR specification `[3]`_.
+
+The multiple-signing domain feature (in current state dual signing domain `[8]`_) allows
+the use of two root keys namely S-ROTPK and NS-ROTPK:
+
+- SPMC (BL32) and SPMC manifest are signed by the SiP using the S-ROTPK.
+- BL33 may be signed by the OEM using NS-ROTPK.
+- An SP may be signed either by SiP (using S-ROTPK) or by OEM (using NS-ROTPK).
+- A maximum of 4 partitions can be signed with the S-ROTPK key and 4 partitions
+  signed with the NS-ROTPK key.
+
+Also refer to `Describing secure partitions`_ and `TF-A build options`_ sections.
+
+Hafnium in the secure world
+===========================
+
+General considerations
+----------------------
+
+Build platform for the secure world
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+In the Hafnium reference implementation specific code parts are only relevant to
+the secure world. Such portions are isolated in architecture specific files
+and/or enclosed by a ``SECURE_WORLD`` macro.
+
+Secure partitions scheduling
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The FF-A specification `[1]`_ provides two ways to relinquinsh CPU time to
+secure partitions. For this a VM (Hypervisor or OS kernel), or SP invokes one of:
+
+- the FFA_MSG_SEND_DIRECT_REQ interface.
+- the FFA_RUN interface.
+
+Additionally a secure interrupt can pre-empt the normal world execution and give
+CPU cycles by transitioning to EL3 and S-EL2.
+
+Platform topology
+~~~~~~~~~~~~~~~~~
+
+The *execution-ctx-count* SP manifest field can take the value of one or the
+total number of PEs. The FF-A specification `[1]`_  recommends the
+following SP types:
+
+- Pinned MP SPs: an execution context matches a physical PE. MP SPs must
+  implement the same number of ECs as the number of PEs in the platform.
+- Migratable UP SPs: a single execution context can run and be migrated on any
+  physical PE. Such SP declares a single EC in its SP manifest. An UP SP can
+  receive a direct message request originating from any physical core targeting
+  the single execution context.
+
+Parsing SP partition manifests
+------------------------------
+
+Hafnium consumes SP manifests as defined in `[1]`_ and `SP manifests`_.
+Note the current implementation may not implement all optional fields.
+
+The SP manifest may contain memory and device regions nodes. In case of
+an S-EL2 SPMC:
+
+- Memory regions are mapped in the SP EL1&0 Stage-2 translation regime at
+  load time (or EL1&0 Stage-1 for an S-EL1 SPMC). A memory region node can
+  specify RX/TX buffer regions in which case it is not necessary for an SP
+  to explicitly invoke the ``FFA_RXTX_MAP`` interface.
+- Device regions are mapped in the SP EL1&0 Stage-2 translation regime (or
+  EL1&0 Stage-1 for an S-EL1 SPMC) as peripherals and possibly allocate
+  additional resources (e.g. interrupts).
+
+For the S-EL2 SPMC, base addresses for memory and device region nodes are IPAs
+provided the SPMC identity maps IPAs to PAs within SP EL1&0 Stage-2 translation
+regime.
+
+Note: in the current implementation both VTTBR_EL2 and VSTTBR_EL2 point to the
+same set of page tables. It is still open whether two sets of page tables shall
+be provided per SP. The memory region node as defined in the specification
+provides a memory security attribute hinting to map either to the secure or
+non-secure EL1&0 Stage-2 table if it exists.
+
+Passing boot data to the SP
+---------------------------
+
+In `[1]`_ , the section  "Boot information protocol" defines a method for passing
+data to the SPs at boot time. It specifies the format for the boot information
+descriptor and boot information header structures, which describe the data to be
+exchanged between SPMC and SP.
+The specification also defines the types of data that can be passed.
+The aggregate of both the boot info structures and the data itself is designated
+the boot information blob, and is passed to a Partition as a contiguous memory
+region.
+
+Currently, the SPM implementation supports the FDT type which is used to pass the
+partition's DTB manifest.
+
+The region for the boot information blob is allocated through the SP package.
+
+.. image:: ../resources/diagrams/partition-package.png
+
+To adjust the space allocated for the boot information blob, the json description
+of the SP (see section `Describing secure partitions`_) shall be updated to contain
+the manifest offset. If no offset is provided the manifest offset defaults to 0x1000,
+which is the page size in the Hafnium SPMC.
+
+The configuration of the boot protocol is done in the SPs manifest. As defined by
+the specification, the manifest field 'gp-register-num' configures the GP register
+which shall be used to pass the address to the partitions boot information blob when
+booting the partition.
+In addition, the Hafnium SPMC implementation requires the boot information arguments
+to be listed in a designated DT node:
+
+.. code:: shell
+
+  boot-info {
+      compatible = "arm,ffa-manifest-boot-info";
+      ffa_manifest;
+  };
+
+The whole secure partition package image (see `Secure Partition packages`_) is
+mapped to the SP secure EL1&0 Stage-2 translation regime. As such, the SP can
+retrieve the address for the boot information blob in the designated GP register,
+process the boot information header and descriptors, access its own manifest
+DTB blob and extract its partition manifest properties.
+
+SP Boot order
+-------------
+
+SP manifests provide an optional boot order attribute meant to resolve
+dependencies such as an SP providing a service required to properly boot
+another SP. SPMC boots the SPs in accordance to the boot order attribute,
+lowest to the highest value. If the boot order attribute is absent from the FF-A
+manifest, the SP is treated as if it had the highest boot order value
+(i.e. lowest booting priority).
+
+It is possible for an SP to call into another SP through a direct request
+provided the latter SP has already been booted.
+
+Boot phases
+-----------
+
+Primary core boot-up
+~~~~~~~~~~~~~~~~~~~~
+
+Upon boot-up, BL31 hands over to the SPMC (BL32) on the primary boot physical
+core. The SPMC performs its platform initializations and registers the SPMC
+secondary physical core entry point physical address by the use of the
+`FFA_SECONDARY_EP_REGISTER`_ interface (SMC invocation from the SPMC to the SPMD
+at secure physical FF-A instance).
+
+The SPMC then creates secure partitions based on SP packages and manifests. Each
+secure partition is launched in sequence (`SP Boot order`_) on their "primary"
+execution context. If the primary boot physical core linear id is N, an MP SP is
+started using EC[N] on PE[N] (see `Platform topology`_). If the partition is a
+UP SP, it is started using its unique EC0 on PE[N].
+
+The SP primary EC (or the EC used when the partition is booted as described
+above):
+
+- Performs the overall SP boot time initialization, and in case of a MP SP,
+  prepares the SP environment for other execution contexts.
+- In the case of a MP SP, it invokes the FFA_SECONDARY_EP_REGISTER at secure
+  virtual FF-A instance (SMC invocation from SP to SPMC) to provide the IPA
+  entry point for other execution contexts.
+- Exits through ``FFA_MSG_WAIT`` to indicate successful initialization or
+  ``FFA_ERROR`` in case of failure.
+
+Secondary cores boot-up
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Once the system is started and NWd brought up, a secondary physical core is
+woken up by the ``PSCI_CPU_ON`` service invocation. The TF-A SPD hook mechanism
+calls into the SPMD on the newly woken up physical core. Then the SPMC is
+entered at the secondary physical core entry point.
+
+In the current implementation, the first SP is resumed on the coresponding EC
+(the virtual CPU which matches the physical core). The implication is that the
+first SP must be a MP SP.
+
+In a linux based system, once secure and normal worlds are booted but prior to
+a NWd FF-A driver has been loaded:
+
+- The first SP has initialized all its ECs in response to primary core boot up
+  (at system initialization) and secondary core boot up (as a result of linux
+  invoking PSCI_CPU_ON for all secondary cores).
+- Other SPs have their first execution context initialized as a result of secure
+  world initialization on the primary boot core. Other ECs for those SPs have to
+  be run first through ffa_run to complete their initialization (which results
+  in the EC completing with FFA_MSG_WAIT).
+
+Refer to `Power management`_ for further details.
+
+Notifications
+-------------
+
+The FF-A v1.1 specification `[1]`_ defines notifications as an asynchronous
+communication mechanism with non-blocking semantics. It allows for one FF-A
+endpoint to signal another for service provision, without hindering its current
+progress.
+
+Hafnium currently supports 64 notifications. The IDs of each notification define
+a position in a 64-bit bitmap.
+
+The signaling of notifications can interchangeably happen between NWd and SWd
+FF-A endpoints.
+
+The SPMC is in charge of managing notifications from SPs to SPs, from SPs to
+VMs, and from VMs to SPs. An hypervisor component would only manage
+notifications from VMs to VMs. Given the SPMC has no visibility of the endpoints
+deployed in NWd, the Hypervisor or OS kernel must invoke the interface
+FFA_NOTIFICATION_BITMAP_CREATE to allocate the notifications bitmap per FF-A
+endpoint in the NWd that supports it.
+
+A sender can signal notifications once the receiver has provided it with
+permissions. Permissions are provided by invoking the interface
+FFA_NOTIFICATION_BIND.
+
+Notifications are signaled by invoking FFA_NOTIFICATION_SET. Henceforth
+they are considered to be in a pending sate. The receiver can retrieve its
+pending notifications invoking FFA_NOTIFICATION_GET, which, from that moment,
+are considered to be handled.
+
+Per the FF-A v1.1 spec, each FF-A endpoint must be associated with a scheduler
+that is in charge of donating CPU cycles for notifications handling. The
+FF-A driver calls FFA_NOTIFICATION_INFO_GET to retrieve the information about
+which FF-A endpoints have pending notifications. The receiver scheduler is
+called and informed by the FF-A driver, and it should allocate CPU cycles to the
+receiver.
+
+There are two types of notifications supported:
+
+- Global, which are targeted to a FF-A endpoint and can be handled within any of
+  its execution contexts, as determined by the scheduler of the system.
+- Per-vCPU, which are targeted to a FF-A endpoint and to be handled within a
+  a specific execution context, as determined by the sender.
+
+The type of a notification is set when invoking FFA_NOTIFICATION_BIND to give
+permissions to the sender.
+
+Notification signaling resorts to two interrupts:
+
+- Schedule Receiver Interrupt: non-secure physical interrupt to be handled by
+  the FF-A driver within the receiver scheduler. At initialization the SPMC
+  donates a SGI ID chosen from the secure SGI IDs range and configures it as
+  non-secure. The SPMC triggers this SGI on the currently running core when
+  there are pending notifications, and the respective receivers need CPU cycles
+  to handle them.
+- Notifications Pending Interrupt: virtual interrupt to be handled by the
+  receiver of the notification. Set when there are pending notifications for the
+  given secure partition. The NPI is pended when the NWd relinquishes CPU cycles
+  to an SP.
+
+The notifications receipt support is enabled in the partition FF-A manifest.
+
+Mandatory interfaces
+--------------------
+
+The following interfaces are exposed to SPs:
+
+-  ``FFA_VERSION``
+-  ``FFA_FEATURES``
+-  ``FFA_RX_RELEASE``
+-  ``FFA_RXTX_MAP``
+-  ``FFA_RXTX_UNMAP``
+-  ``FFA_PARTITION_INFO_GET``
+-  ``FFA_ID_GET``
+-  ``FFA_MSG_WAIT``
+-  ``FFA_MSG_SEND_DIRECT_REQ``
+-  ``FFA_MSG_SEND_DIRECT_RESP``
+-  ``FFA_MEM_DONATE``
+-  ``FFA_MEM_LEND``
+-  ``FFA_MEM_SHARE``
+-  ``FFA_MEM_RETRIEVE_REQ``
+-  ``FFA_MEM_RETRIEVE_RESP``
+-  ``FFA_MEM_RELINQUISH``
+-  ``FFA_MEM_FRAG_RX``
+-  ``FFA_MEM_FRAG_TX``
+-  ``FFA_MEM_RECLAIM``
+-  ``FFA_RUN``
+
+As part of the FF-A v1.1 support, the following interfaces were added:
+
+ - ``FFA_NOTIFICATION_BITMAP_CREATE``
+ - ``FFA_NOTIFICATION_BITMAP_DESTROY``
+ - ``FFA_NOTIFICATION_BIND``
+ - ``FFA_NOTIFICATION_UNBIND``
+ - ``FFA_NOTIFICATION_SET``
+ - ``FFA_NOTIFICATION_GET``
+ - ``FFA_NOTIFICATION_INFO_GET``
+ - ``FFA_SPM_ID_GET``
+ - ``FFA_SECONDARY_EP_REGISTER``
+ - ``FFA_MEM_PERM_GET``
+ - ``FFA_MEM_PERM_SET``
+ - ``FFA_MSG_SEND2``
+ - ``FFA_RX_ACQUIRE``
+
+FFA_VERSION
+~~~~~~~~~~~
+
+``FFA_VERSION`` requires a *requested_version* parameter from the caller.
+The returned value depends on the caller:
+
+- Hypervisor or OS kernel in NS-EL1/EL2: the SPMD returns the SPMC version
+  specified in the SPMC manifest.
+- SP: the SPMC returns its own implemented version.
+- SPMC at S-EL1/S-EL2: the SPMD returns its own implemented version.
+
+FFA_FEATURES
+~~~~~~~~~~~~
+
+FF-A features supported by the SPMC may be discovered by secure partitions at
+boot (that is prior to NWd is booted) or run-time.
+
+The SPMC calling FFA_FEATURES at secure physical FF-A instance always get
+FFA_SUCCESS from the SPMD.
+
+The request made by an Hypervisor or OS kernel is forwarded to the SPMC and
+the response relayed back to the NWd.
+
+FFA_RXTX_MAP/FFA_RXTX_UNMAP
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+When invoked from a secure partition FFA_RXTX_MAP maps the provided send and
+receive buffers described by their IPAs to the SP EL1&0 Stage-2 translation
+regime as secure buffers in the MMU descriptors.
+
+When invoked from the Hypervisor or OS kernel, the buffers are mapped into the
+SPMC EL2 Stage-1 translation regime and marked as NS buffers in the MMU
+descriptors. The provided addresses may be owned by a VM in the normal world,
+which is expected to receive messages from the secure world. The SPMC will in
+this case allocate internal state structures to facilitate RX buffer access
+synchronization (through FFA_RX_ACQUIRE interface), and to permit SPs to send
+messages.
+
+The FFA_RXTX_UNMAP unmaps the RX/TX pair from the translation regime of the
+caller, either it being the Hypervisor or OS kernel, as well as a secure
+partition.
+
+FFA_PARTITION_INFO_GET
+~~~~~~~~~~~~~~~~~~~~~~
+
+Partition info get call can originate:
+
+- from SP to SPMC
+- from Hypervisor or OS kernel to SPMC. The request is relayed by the SPMD.
+
+FFA_ID_GET
+~~~~~~~~~~
+
+The FF-A id space is split into a non-secure space and secure space:
+
+- FF-A ID with bit 15 clear relates to VMs.
+- FF-A ID with bit 15 set related to SPs.
+- FF-A IDs 0, 0xffff, 0x8000 are assigned respectively to the Hypervisor, SPMD
+  and SPMC.
+
+The SPMD returns:
+
+- The default zero value on invocation from the Hypervisor.
+- The ``spmc_id`` value specified in the SPMC manifest on invocation from
+  the SPMC (see `SPMC manifest`_)
+
+This convention helps the SPMC to determine the origin and destination worlds in
+an FF-A ABI invocation. In particular the SPMC shall filter unauthorized
+transactions in its world switch routine. It must not be permitted for a VM to
+use a secure FF-A ID as origin world by spoofing:
+
+- A VM-to-SP direct request/response shall set the origin world to be non-secure
+  (FF-A ID bit 15 clear) and destination world to be secure (FF-A ID bit 15
+  set).
+- Similarly, an SP-to-SP direct request/response shall set the FF-A ID bit 15
+  for both origin and destination IDs.
+
+An incoming direct message request arriving at SPMD from NWd is forwarded to
+SPMC without a specific check. The SPMC is resumed through eret and "knows" the
+message is coming from normal world in this specific code path. Thus the origin
+endpoint ID must be checked by SPMC for being a normal world ID.
+
+An SP sending a direct message request must have bit 15 set in its origin
+endpoint ID and this can be checked by the SPMC when the SP invokes the ABI.
+
+The SPMC shall reject the direct message if the claimed world in origin endpoint
+ID is not consistent:
+
+-  It is either forwarded by SPMD and thus origin endpoint ID must be a "normal
+   world ID",
+-  or initiated by an SP and thus origin endpoint ID must be a "secure world ID".
+
+
+FFA_MSG_SEND_DIRECT_REQ/FFA_MSG_SEND_DIRECT_RESP
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This is a mandatory interface for secure partitions consisting in direct request
+and responses with the following rules:
+
+- An SP can send a direct request to another SP.
+- An SP can receive a direct request from another SP.
+- An SP can send a direct response to another SP.
+- An SP cannot send a direct request to an Hypervisor or OS kernel.
+- An Hypervisor or OS kernel can send a direct request to an SP.
+- An SP can send a direct response to an Hypervisor or OS kernel.
+
+FFA_NOTIFICATION_BITMAP_CREATE/FFA_NOTIFICATION_BITMAP_DESTROY
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The secure partitions notifications bitmap are statically allocated by the SPMC.
+Hence, this interface is not to be issued by secure partitions.
+
+At initialization, the SPMC is not aware of VMs/partitions deployed in the
+normal world. Hence, the Hypervisor or OS kernel must use both ABIs for SPMC
+to be prepared to handle notifications for the provided VM ID.
+
+FFA_NOTIFICATION_BIND/FFA_NOTIFICATION_UNBIND
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Pair of interfaces to manage permissions to signal notifications. Prior to
+handling notifications, an FF-A endpoint must allow a given sender to signal a
+bitmap of notifications.
+
+If the receiver doesn't have notification support enabled in its FF-A manifest,
+it won't be able to bind notifications, hence forbidding it to receive any
+notifications.
+
+FFA_NOTIFICATION_SET/FFA_NOTIFICATION_GET
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+FFA_NOTIFICATION_GET retrieves all pending global notifications and
+per-vCPU notifications targeted to the current vCPU.
+
+Hafnium maintains a global count of pending notifications which gets incremented
+and decremented when handling FFA_NOTIFICATION_SET and FFA_NOTIFICATION_GET
+respectively. A delayed SRI is triggered if the counter is non-zero when the
+SPMC returns to normal world.
+
+FFA_NOTIFICATION_INFO_GET
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Hafnium maintains a global count of pending notifications whose information
+has been retrieved by this interface. The count is incremented and decremented
+when handling FFA_NOTIFICATION_INFO_GET and FFA_NOTIFICATION_GET respectively.
+It also tracks notifications whose information has been retrieved individually,
+such that it avoids duplicating returned information for subsequent calls to
+FFA_NOTIFICATION_INFO_GET. For each notification, this state information is
+reset when receiver called FFA_NOTIFICATION_GET to retrieve them.
+
+FFA_SPM_ID_GET
+~~~~~~~~~~~~~~
+
+Returns the FF-A ID allocated to an SPM component which can be one of SPMD
+or SPMC.
+
+At initialization, the SPMC queries the SPMD for the SPMC ID, using the
+FFA_ID_GET interface, and records it. The SPMC can also query the SPMD ID using
+the FFA_SPM_ID_GET interface at the secure physical FF-A instance.
+
+Secure partitions call this interface at the virtual FF-A instance, to which
+the SPMC returns the priorly retrieved SPMC ID.
+
+The Hypervisor or OS kernel can issue the FFA_SPM_ID_GET call handled by the
+SPMD, which returns the SPMC ID.
+
+FFA_SECONDARY_EP_REGISTER
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+When the SPMC boots, all secure partitions are initialized on their primary
+Execution Context.
+
+The FFA_SECONDARY_EP_REGISTER interface is to be used by a secure partition
+from its first execution context, to provide the entry point address for
+secondary execution contexts.
+
+A secondary EC is first resumed either upon invocation of PSCI_CPU_ON from
+the NWd or by invocation of FFA_RUN.
+
+FFA_RX_ACQUIRE/FFA_RX_RELEASE
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The RX buffers can be used to pass information to an FF-A endpoint in the
+following scenarios:
+
+ - When it was targetted by a FFA_MSG_SEND2 invokation from another endpoint.
+ - Return the result of calling ``FFA_PARTITION_INFO_GET``.
+ - In a memory share operation, as part of the ``FFA_MEM_RETRIEVE_RESP``,
+   with the memory descriptor of the shared memory.
+
+If a normal world VM is expected to exchange messages with secure world,
+its RX/TX buffer addresses are forwarded to the SPMC via FFA_RXTX_MAP ABI,
+and are from this moment owned by the SPMC.
+The hypervisor must call the FFA_RX_ACQUIRE interface before attempting
+to use the RX buffer, in any of the aforementioned scenarios. A successful
+call to FFA_RX_ACQUIRE transfers ownership of RX buffer to hypervisor, such
+that it can be safely used.
+
+The FFA_RX_RELEASE interface is used after the FF-A endpoint is done with
+processing the data received in its RX buffer. If the RX buffer has been
+acquired by the hypervisor, the FFA_RX_RELEASE call must be forwarded to
+the SPMC to reestablish SPMC's RX ownership.
+
+An attempt from an SP to send a message to a normal world VM whose RX buffer
+was acquired by the hypervisor fails with error code FFA_BUSY, to preserve
+the RX buffer integrity.
+The operation could then be conducted after FFA_RX_RELEASE.
+
+FFA_MSG_SEND2
+~~~~~~~~~~~~~
+
+Hafnium copies a message from the sender TX buffer into receiver's RX buffer.
+For messages from SPs to VMs, operation is only possible if the SPMC owns
+the receiver's RX buffer.
+
+Both receiver and sender need to enable support for indirect messaging,
+in their respective partition manifest. The discovery of support
+of such feature can be done via FFA_PARTITION_INFO_GET.
+
+On a successful message send, Hafnium pends an RX buffer full framework
+notification for the receiver, to inform it about a message in the RX buffer.
+
+The handling of framework notifications is similar to that of
+global notifications. Binding of these is not necessary, as these are
+reserved to be used by the hypervisor or SPMC.
+
+SPMC-SPMD direct requests/responses
+-----------------------------------
+
+Implementation-defined FF-A IDs are allocated to the SPMC and SPMD.
+Using those IDs in source/destination fields of a direct request/response
+permits SPMD to SPMC communication and either way.
+
+- SPMC to SPMD direct request/response uses SMC conduit.
+- SPMD to SPMC direct request/response uses ERET conduit.
+
+This is used in particular to convey power management messages.
+
+PE MMU configuration
+--------------------
+
+With secure virtualization enabled (``HCR_EL2.VM = 1``) and for S-EL1
+partitions, two IPA spaces (secure and non-secure) are output from the
+secure EL1&0 Stage-1 translation.
+The EL1&0 Stage-2 translation hardware is fed by:
+
+- A secure IPA when the SP EL1&0 Stage-1 MMU is disabled.
+- One of secure or non-secure IPA when the secure EL1&0 Stage-1 MMU is enabled.
+
+``VTCR_EL2`` and ``VSTCR_EL2`` provide configuration bits for controlling the
+NS/S IPA translations. The following controls are set up:
+``VSTCR_EL2.SW = 0`` , ``VSTCR_EL2.SA = 0``, ``VTCR_EL2.NSW = 0``,
+``VTCR_EL2.NSA = 1``:
+
+- Stage-2 translations for the NS IPA space access the NS PA space.
+- Stage-2 translation table walks for the NS IPA space are to the secure PA space.
+
+Secure and non-secure IPA regions (rooted to by ``VTTBR_EL2`` and ``VSTTBR_EL2``)
+use the same set of Stage-2 page tables within a SP.
+
+The ``VTCR_EL2/VSTCR_EL2/VTTBR_EL2/VSTTBR_EL2`` virtual address space
+configuration is made part of a vCPU context.
+
+For S-EL0 partitions with VHE enabled, a single secure EL2&0 Stage-1 translation
+regime is used for both Hafnium and the partition.
+
+Schedule modes and SP Call chains
+---------------------------------
+
+An SP execution context is said to be in SPMC scheduled mode if CPU cycles are
+allocated to it by SPMC. Correspondingly, an SP execution context is said to be
+in Normal world scheduled mode if CPU cycles are allocated by the normal world.
+
+A call chain represents all SPs in a sequence of invocations of a direct message
+request. When execution on a PE is in the secure state, only a single call chain
+that runs in the Normal World scheduled mode can exist. FF-A v1.1 spec allows
+any number of call chains to run in the SPMC scheduled mode but the Hafnium
+SPMC restricts the number of call chains in SPMC scheduled mode to only one for
+keeping the implementation simple.
+
+Partition runtime models
+------------------------
+
+The runtime model of an endpoint describes the transitions permitted for an
+execution context between various states. These are the four partition runtime
+models supported (refer to `[1]`_ section 7):
+
+  - RTM_FFA_RUN: runtime model presented to an execution context that is
+    allocated CPU cycles through FFA_RUN interface.
+  - RTM_FFA_DIR_REQ: runtime model presented to an execution context that is
+    allocated CPU cycles through FFA_MSG_SEND_DIRECT_REQ interface.
+  - RTM_SEC_INTERRUPT: runtime model presented to an execution context that is
+    allocated CPU cycles by SPMC to handle a secure interrupt.
+  - RTM_SP_INIT: runtime model presented to an execution context that is
+    allocated CPU cycles by SPMC to initialize its state.
+
+If an endpoint execution context attempts to make an invalid transition or a
+valid transition that could lead to a loop in the call chain, SPMC denies the
+transition with the help of above runtime models.
+
+Interrupt management
+--------------------
+
+GIC ownership
+~~~~~~~~~~~~~
+
+The SPMC owns the GIC configuration. Secure and non-secure interrupts are
+trapped at S-EL2. The SPMC manages interrupt resources and allocates interrupt
+IDs based on SP manifests. The SPMC acknowledges physical interrupts and injects
+virtual interrupts by setting the use of vIRQ/vFIQ bits before resuming a SP.
+
+Abbreviations:
+
+  - NS-Int: A non-secure physical interrupt. It requires a switch to the normal
+    world to be handled if it triggers while execution is in secure world.
+  - Other S-Int: A secure physical interrupt targeted to an SP different from
+    the one that is currently running.
+  - Self S-Int: A secure physical interrupt targeted to the SP that is currently
+    running.
+
+Non-secure interrupt handling
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This section documents the actions supported in SPMC in response to a non-secure
+interrupt as per the guidance provided by FF-A v1.1 EAC0 specification.
+An SP specifies one of the following actions in its partition manifest:
+
+  - Non-secure interrupt is signaled.
+  - Non-secure interrupt is signaled after a managed exit.
+  - Non-secure interrupt is queued.
+
+An SP execution context in a call chain could specify a less permissive action
+than subsequent SP execution contexts in the same call chain. The less
+permissive action takes precedence over the more permissive actions specified
+by the subsequent execution contexts. Please refer to FF-A v1.1 EAC0 section
+8.3.1 for further explanation.
+
+Secure interrupt handling
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This section documents the support implemented for secure interrupt handling in
+SPMC as per the guidance provided by FF-A v1.1 EAC0 specification.
+The following assumptions are made about the system configuration:
+
+  - In the current implementation, S-EL1 SPs are expected to use the para
+    virtualized ABIs for interrupt management rather than accessing the virtual
+    GIC interface.
+  - Unless explicitly stated otherwise, this support is applicable only for
+    S-EL1 SPs managed by SPMC.
+  - Secure interrupts are configured as G1S or G0 interrupts.
+  - All physical interrupts are routed to SPMC when running a secure partition
+    execution context.
+  - All endpoints with multiple execution contexts have their contexts pinned
+    to corresponding CPUs. Hence, a secure virtual interrupt cannot be signaled
+    to a target vCPU that is currently running or blocked on a different
+    physical CPU.
+
+A physical secure interrupt could trigger while CPU is executing in normal world
+or secure world.
+The action of SPMC for a secure interrupt depends on: the state of the target
+execution context of the SP that is responsible for handling the interrupt;
+whether the interrupt triggered while execution was in normal world or secure
+world.
+
+Secure interrupt signaling mechanisms
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Signaling refers to the mechanisms used by SPMC to indicate to the SP execution
+context that it has a pending virtual interrupt and to further run the SP
+execution context, such that it can handle the virtual interrupt. SPMC uses
+either the FFA_INTERRUPT interface with ERET conduit or vIRQ signal for signaling
+to S-EL1 SPs. When normal world execution is preempted by a secure interrupt,
+the SPMD uses the FFA_INTERRUPT ABI with ERET conduit to signal interrupt to SPMC
+running in S-EL2.
+
++-----------+---------+---------------+---------------------------------------+

++-----------+---------+---------------+---------------------------------------+
+
+Secure interrupt completion mechanisms
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+A SP signals secure interrupt handling completion to the SPMC through the
+following mechanisms:
+
+  - ``FFA_MSG_WAIT`` ABI if it was in WAITING state.
+  - ``FFA_RUN`` ABI if its was in BLOCKED state.
+
+This is a remnant of SPMC implementation based on the FF-A v1.0 specification.
+In the current implementation, S-EL1 SPs use the para-virtualized HVC interface
+implemented by SPMC to perform priority drop and interrupt deactivation (SPMC
+configures EOImode = 0, i.e. priority drop and deactivation are done together).
+The SPMC performs checks to deny the state transition upon invocation of
+either FFA_MSG_WAIT or FFA_RUN interface if the SP didn't perform the
+deactivation of the secure virtual interrupt.
+
+If the current SP execution context was preempted by a secure interrupt to be
+handled by execution context of target SP, SPMC resumes current SP after signal
+completion by target SP execution context.
+
+Actions for a secure interrupt triggered while execution is in normal world

+|                   |          | when the target execution context next enters |
+|                   |          | the RUNNING state.                            |

+|                   |          | running on a different CPU. This is not       |
+|                   |          | supported by current SPMC implementation and  |
+|                   |          | execution hits panic.                         |
++-------------------+----------+-----------------------------------------------+
+
+If normal world execution was preempted by a secure interrupt, SPMC uses
+FFA_NORMAL_WORLD_RESUME ABI to indicate completion of secure interrupt handling
+and further returns execution to normal world.
+
+The following figure describes interrupt handling flow when a secure interrupt
+triggers while execution is in normal world:
+
+.. image:: ../resources/diagrams/ffa-secure-interrupt-handling-nwd.png
+
+A brief description of the events:
+
+  - 1) Secure interrupt triggers while normal world is running.
+  - 2) FIQ gets trapped to EL3.
+  - 3) SPMD signals secure interrupt to SPMC at S-EL2 using FFA_INTERRUPT ABI.
+  - 4) SPMC identifies target vCPU of SP and injects virtual interrupt (pends
+       vIRQ).
+  - 5) Assuming SP1 vCPU is in WAITING state, SPMC signals virtual interrupt
+       using FFA_INTERRUPT with interrupt id as an argument and resumes the SP1
+       vCPU using ERET in SPMC scheduled mode.
+  - 6) Execution traps to vIRQ handler in SP1 provided that the virtual
+       interrupt is not masked i.e., PSTATE.I = 0
+  - 7) SP1 queries for the pending virtual interrupt id using a paravirtualized
+       HVC call. SPMC clears the pending virtual interrupt state management
+       and returns the pending virtual interrupt id.
+  - 8) SP1 services the virtual interrupt and invokes the paravirtualized
+       de-activation HVC call. SPMC de-activates the physical interrupt,
+       clears the fields tracking the secure interrupt and resumes SP1 vCPU.
+  - 9) SP1 performs secure interrupt completion through FFA_MSG_WAIT ABI.
+  - 10) SPMC returns control to EL3 using FFA_NORMAL_WORLD_RESUME.
+  - 11) EL3 resumes normal world execution.

+|                   |          | context next enters the RUNNING state.         |
++-------------------+----------+------------------------------------------------+

+
+The following figure describes interrupt handling flow when a secure interrupt
+triggers while execution is in secure world. We assume OS kernel sends a direct
+request message to SP1. Further, SP1 sends a direct request message to SP2. SP1
+enters BLOCKED state and SPMC resumes SP2.
+
+.. image:: ../resources/diagrams/ffa-secure-interrupt-handling-swd.png
+
+A brief description of the events:
+
+  - 1) Secure interrupt triggers while SP2 is running.
+  - 2) SP2 gets preempted and execution traps to SPMC as IRQ.
+  - 3) SPMC finds the target vCPU of secure partition responsible for handling
+       this secure interrupt. In this scenario, it is SP1.
+  - 4) SPMC pends vIRQ for SP1 and signals through FFA_INTERRUPT interface.
+       SPMC further resumes SP1 through ERET conduit. Note that SP1 remains in
+       Normal world schedule mode.
+  - 6) Execution traps to vIRQ handler in SP1 provided that the virtual
+       interrupt is not masked i.e., PSTATE.I = 0
+  - 7) SP1 queries for the pending virtual interrupt id using a paravirtualized
+       HVC call. SPMC clears the pending virtual interrupt state management
+       and returns the pending virtual interrupt id.
+  - 8) SP1 services the virtual interrupt and invokes the paravirtualized
+       de-activation HVC call. SPMC de-activates the physical interrupt and
+       clears the fields tracking the secure interrupt and resumes SP1 vCPU.
+  - 9) Since SP1 direct request completed with FFA_INTERRUPT, it resumes the
+       direct request to SP2 by invoking FFA_RUN.
+  - 9) SPMC resumes the pre-empted vCPU of SP2.
+
+Power management
+----------------
+
+In platforms with or without secure virtualization:
+
+- The NWd owns the platform PM policy.
+- The Hypervisor or OS kernel is the component initiating PSCI service calls.
+- The EL3 PSCI library is in charge of the PM coordination and control
+  (eventually writing to platform registers).
+- While coordinating PM events, the PSCI library calls backs into the Secure
+  Payload Dispatcher for events the latter has statically registered to.
+
+When using the SPMD as a Secure Payload Dispatcher:
+
+- A power management event is relayed through the SPD hook to the SPMC.
+- In the current implementation only cpu on (svc_on_finish) and cpu off
+  (svc_off) hooks are registered.
+- The behavior for the cpu on event is described in `Secondary cores boot-up`_.
+  The SPMC is entered through its secondary physical core entry point.
+- The cpu off event occurs when the NWd calls PSCI_CPU_OFF. The PM event is
+  signaled to the SPMC through a power management framework message.
+  It consists in a SPMD-to-SPMC direct request/response (`SPMC-SPMD direct
+  requests/responses`_) conveying the event details and SPMC response.
+  The SPMD performs a synchronous entry into the SPMC. The SPMC is entered and
+  updates its internal state to reflect the physical core is being turned off.
+  In the current implementation no SP is resumed as a consequence. This behavior
+  ensures a minimal support for CPU hotplug e.g. when initiated by the NWd linux
+  userspace.
+
+Arm architecture extensions for security hardening
+==================================================
+
+Hafnium supports the following architecture extensions for security hardening:
+
+- Pointer authentication (FEAT_PAuth): the extension permits detection of forged
+  pointers used by ROP type of attacks through the signing of the pointer
+  value. Hafnium is built with the compiler branch protection option to permit
+  generation of a pointer authentication code for return addresses (pointer
+  authentication for instructions). The APIA key is used while Hafnium runs.
+  A random key is generated at boot time and restored upon entry into Hafnium
+  at run-time. APIA and other keys (APIB, APDA, APDB, APGA) are saved/restored
+  in vCPU contexts permitting to enable pointer authentication in VMs/SPs.
+- Branch Target Identification (FEAT_BTI): the extension permits detection of
+  unexpected indirect branches used by JOP type of attacks. Hafnium is built
+  with the compiler branch protection option, inserting land pads at function
+  prologues that are reached by indirect branch instructions (BR/BLR).
+  Hafnium code pages are marked as guarded in the EL2 Stage-1 MMU descriptors
+  such that an indirect branch must always target a landpad. A fault is
+  triggered otherwise. VMs/SPs can (independently) mark their code pages as
+  guarded in the EL1&0 Stage-1 translation regime.
+- Memory Tagging Extension (FEAT_MTE): the option permits detection of out of
+  bound memory array accesses or re-use of an already freed memory region.
+  Hafnium enables the compiler option permitting to leverage MTE stack tagging
+  applied to core stacks. Core stacks are marked as normal tagged memory in the
+  EL2 Stage-1 translation regime. A synchronous data abort is generated upon tag
+  check failure on load/stores. A random seed is generated at boot time and
+  restored upon entry into Hafnium. MTE system registers are saved/restored in
+  vCPU contexts permitting MTE usage from VMs/SPs.
+
+SMMUv3 support in Hafnium
+=========================
+
+An SMMU is analogous to an MMU in a CPU. It performs address translations for
+Direct Memory Access (DMA) requests from system I/O devices.
+The responsibilities of an SMMU include:
+
+-  Translation: Incoming DMA requests are translated from bus address space to
+   system physical address space using translation tables compliant to
+   Armv8/Armv7 VMSA descriptor format.
+-  Protection: An I/O device can be prohibited from read, write access to a
+   memory region or allowed.
+-  Isolation: Traffic from each individial device can be independently managed.
+   The devices are differentiated from each other using unique translation
+   tables.
+
+The following diagram illustrates a typical SMMU IP integrated in a SoC with
+several I/O devices along with Interconnect and Memory system.
+
+.. image:: ../resources/diagrams/MMU-600.png
+
+SMMU has several versions including SMMUv1, SMMUv2 and SMMUv3. Hafnium provides
+support for SMMUv3 driver in both normal and secure world. A brief introduction
+of SMMUv3 functionality and the corresponding software support in Hafnium is
+provided here.
+
+SMMUv3 features
+---------------
+
+-  SMMUv3 provides Stage1, Stage2 translation as well as nested (Stage1 + Stage2)
+   translation support. It can either bypass or abort incoming translations as
+   well.
+-  Traffic (memory transactions) from each upstream I/O peripheral device,
+   referred to as Stream, can be independently managed using a combination of
+   several memory based configuration structures. This allows the SMMUv3 to
+   support a large number of streams with each stream assigned to a unique
+   translation context.
+-  Support for Armv8.1 VMSA where the SMMU shares the translation tables with
+   a Processing Element. AArch32(LPAE) and AArch64 translation table format
+   are supported by SMMUv3.
+-  SMMUv3 offers non-secure stream support with secure stream support being
+   optional. Logically, SMMUv3 behaves as if there is an indepdendent SMMU
+   instance for secure and non-secure stream support.
+-  It also supports sub-streams to differentiate traffic from a virtualized
+   peripheral associated with a VM/SP.
+-  Additionally, SMMUv3.2 provides support for PEs implementing Armv8.4-A
+   extensions. Consequently, SPM depends on Secure EL2 support in SMMUv3.2
+   for providing Secure Stage2 translation support to upstream peripheral
+   devices.
+
+SMMUv3 Programming Interfaces
+-----------------------------
+
+SMMUv3 has three software interfaces that are used by the Hafnium driver to
+configure the behaviour of SMMUv3 and manage the streams.
+
+-  Memory based data strutures that provide unique translation context for
+   each stream.
+-  Memory based circular buffers for command queue and event queue.
+-  A large number of SMMU configuration registers that are memory mapped during
+   boot time by Hafnium driver. Except a few registers, all configuration
+   registers have independent secure and non-secure versions to configure the
+   behaviour of SMMUv3 for translation of secure and non-secure streams
+   respectively.
+
+Peripheral device manifest
+--------------------------
+
+Currently, SMMUv3 driver in Hafnium only supports dependent peripheral devices.
+These devices are dependent on PE endpoint to initiate and receive memory
+management transactions on their behalf. The acccess to the MMIO regions of
+any such device is assigned to the endpoint during boot. Moreover, SMMUv3 driver
+uses the same stage 2 translations for the device as those used by partition
+manager on behalf of the PE endpoint. This ensures that the peripheral device
+has the same visibility of the physical address space as the endpoint. The
+device node of the corresponding partition manifest (refer to `[1]`_ section 3.2
+) must specify these additional properties for each peripheral device in the
+system :
+
+-  smmu-id: This field helps to identify the SMMU instance that this device is
+   upstream of.
+-  stream-ids: List of stream IDs assigned to this device.
+
+.. code:: shell
+
+    smmuv3-testengine {
+        base-address = <0x00000000 0x2bfe0000>;
+        pages-count = <32>;
+        attributes = <0x3>;
+        smmu-id = <0>;
+        stream-ids = <0x0 0x1>;
+        interrupts = <0x2 0x3>, <0x4 0x5>;
+        exclusive-access;
+    };
+
+SMMUv3 driver limitations
+-------------------------
+
+The primary design goal for the Hafnium SMMU driver is to support secure
+streams.
+
+-  Currently, the driver only supports Stage2 translations. No support for
+   Stage1 or nested translations.
+-  Supports only AArch64 translation format.
+-  No support for features such as PCI Express (PASIDs, ATS, PRI), MSI, RAS,
+   Fault handling, Performance Monitor Extensions, Event Handling, MPAM.
+-  No support for independent peripheral devices.
+
+S-EL0 Partition support
+=======================
+The SPMC (Hafnium) has limited capability to run S-EL0 FF-A partitions using
+FEAT_VHE (mandatory with ARMv8.1 in non-secure state, and in secure world
+with ARMv8.4 and FEAT_SEL2).
+
+S-EL0 partitions are useful for simple partitions that don't require full
+Trusted OS functionality. It is also useful to reduce jitter and cycle
+stealing from normal world since they are more lightweight than VMs.
+
+S-EL0 partitions are presented, loaded and initialized the same as S-EL1 VMs by
+the SPMC. They are differentiated primarily by the 'exception-level' property
+and the 'execution-ctx-count' property in the SP manifest. They are host apps
+under the single EL2&0 Stage-1 translation regime controlled by the SPMC and
+call into the SPMC through SVCs as opposed to HVCs and SMCs. These partitions
+can use FF-A defined services (FFA_MEM_PERM_*) to update or change permissions
+for memory regions.
+
+S-EL0 partitions are required by the FF-A specification to be UP endpoints,
+capable of migrating, and the SPMC enforces this requirement. The SPMC allows
+a S-EL0 partition to accept a direct message from secure world and normal world,
+and generate direct responses to them.
+All S-EL0 partitions must use AArch64. AArch32 S-EL0 partitions are not supported.
+
+Memory sharing, indirect messaging, and notifications functionality with S-EL0
+partitions is supported.
+
+Interrupt handling is not supported with S-EL0 partitions and is work in
+progress.

+Trusted Little Kernel (TLK) Dispatcher
+======================================
+
+TLK dispatcher (TLK-D) adds support for NVIDIA's Trusted Little Kernel (TLK)
+to work with Trusted Firmware-A (TF-A). TLK-D can be compiled by including it
+in the platform's makefile. TLK is primarily meant to work with Tegra SoCs,
+so while TF-A only supports TLK on Tegra, the dispatcher code can only be
+compiled for other platforms.
+
+In order to compile TLK-D, we need a BL32 image to be present. Since, TLKD
+just needs to compile, any BL32 image would do. To use TLK as the BL32, please
+refer to the "Build TLK" section.
+
+Once a BL32 is ready, TLKD can be included in the image by adding "SPD=tlkd"
+to the build command.
+
+Trusted Little Kernel (TLK)
+---------------------------
+
+TLK is a Trusted OS running as Secure EL1. It is a Free Open Source Software
+(FOSS) release of the NVIDIA® Trusted Little Kernel (TLK) technology, which
+extends technology made available with the development of the Little Kernel (LK).
+You can download the LK modular embedded preemptive kernel for use on Arm,
+x86, and AVR32 systems from https://github.com/travisg/lk
+
+NVIDIA implemented its Trusted Little Kernel (TLK) technology, designed as a
+free and open-source trusted execution environment (OTE).
+
+TLK features include:
+
+• Small, pre-emptive kernel
+• Supports multi-threading, IPCs, and thread scheduling
+• Added TrustZone features
+• Added Secure Storage
+• Under MIT/FreeBSD license
+
+NVIDIA extensions to Little Kernel (LK) include:
+
+• User mode
+• Address-space separation for TAs
+• TLK Client Application (CA) library
+• TLK TA library
+• Crypto library (encrypt/decrypt, key handling) via OpenSSL
+• Linux kernel driver
+• Cortex A9/A15 support
+• Power Management
+• TrustZone memory carve-out (reconfigurable)
+• Page table management
+• Debugging support over UART (USB planned)
+
+TLK is hosted by NVIDIA on http://nv-tegra.nvidia.com under the
+3rdparty/ote\_partner/tlk.git repository. Detailed information about
+TLK and OTE can be found in the Tegra\_BSP\_for\_Android\_TLK\_FOSS\_Reference.pdf
+manual located under the "documentation" directory\_.
+
+Build TLK
+---------
+
+To build and execute TLK, follow the instructions from "Building a TLK Device"
+section from Tegra\_BSP\_for\_Android\_TLK\_FOSS\_Reference.pdf manual.
+
+Input parameters to TLK
+-----------------------
+
+TLK expects the TZDRAM size and a structure containing the boot arguments. BL2
+passes this information to the EL3 software as members of the bl32\_ep\_info
+struct, where bl32\_ep\_info is part of bl31\_params\_t (passed by BL2 in X0)
+
+Example
+~~~~~~~
+
+::
+
+    bl32_ep_info->args.arg0 = TZDRAM size available for BL32
+    bl32_ep_info->args.arg1 = unused (used only on Armv7-A)
+    bl32_ep_info->args.arg2 = pointer to boot args

+Trusty Dispatcher
+=================
+
+Trusty is a a set of software components, supporting a Trusted Execution
+Environment (TEE) on mobile devices, published and maintained by Google.
+
+Detailed information and build instructions can be found on the Android
+Open Source Project (AOSP) webpage for Trusty hosted at
+https://source.android.com/security/trusty
+
+Boot parameters
+---------------
+
+Custom boot parameters can be passed to Trusty by providing a platform
+specific function:
+
+.. code:: c
+
+    void plat_trusty_set_boot_args(aapcs64_params_t *args)
+
+If this function is provided ``args->arg0`` must be set to the memory
+size allocated to trusty. If the platform does not provide this
+function, but defines ``TSP_SEC_MEM_SIZE``, a default implementation
+will pass the memory size from ``TSP_SEC_MEM_SIZE``. ``args->arg1``
+can be set to a platform specific parameter block, and ``args->arg2``
+should then be set to the size of that block.
+
+Supported platforms
+-------------------
+
+Out of all the platforms supported by Trusted Firmware-A, Trusty is only
+verified and supported by NVIDIA's Tegra SoCs.

+Translation (XLAT) Tables Library
+=================================
+
+This document describes the design of the translation tables library (version 2)
+used by Trusted Firmware-A (TF-A). This library provides APIs to create page
+tables based on a description of the memory layout, as well as setting up system
+registers related to the Memory Management Unit (MMU) and performing the
+required Translation Lookaside Buffer (TLB) maintenance operations.
+
+More specifically, some use cases that this library aims to support are:
+
+#. Statically allocate translation tables and populate them (at run-time) based
+   upon a description of the memory layout. The memory layout is typically
+   provided by the platform port as a list of memory regions;
+
+#. Support for generating translation tables pertaining to a different
+   translation regime than the exception level the library code is executing at;
+
+#. Support for dynamic mapping and unmapping of regions, even while the MMU is
+   on. This can be used to temporarily map some memory regions and unmap them
+   later on when no longer needed;
+
+#. Support for non-identity virtual to physical mappings to compress the virtual
+   address space;
+
+#. Support for changing memory attributes of memory regions at run-time.
+
+
+About version 1, version 2 and MPU libraries
+--------------------------------------------
+
+This document focuses on version 2 of the library, whose sources are available
+in the ``lib/xlat_tables_v2`` directory. Version 1 of the library can still be
+found in ``lib/xlat_tables`` directory but it is less flexible and doesn't
+support dynamic mapping. ``lib/xlat_mpu``, which configures Arm's MPU
+equivalently, is also addressed here. The ``lib/xlat_mpu`` is experimental,
+meaning that its API may change. It currently strives for consistency and
+code-reuse with xlat_tables_v2.  Future versions may be more MPU-specific (e.g.,
+removing all mentions of virtual addresses). Although potential bug fixes will
+be applied to all versions of the xlat_* libs, future feature enhancements will
+focus on version 2 and might not be back-ported to version 1 and MPU versions.
+Therefore, it is recommended to use version 2, especially for new platform
+ports (unless the platform uses an MPU).
+
+However, please note that version 2 and the MPU version are still in active
+development and is not considered stable yet. Hence, compatibility breaks might
+be introduced.
+
+From this point onwards, this document will implicitly refer to version 2 of the
+library, unless stated otherwise.
+
+
+Design concepts and interfaces
+------------------------------
+
+This section presents some of the key concepts and data structures used in the
+translation tables library.
+
+`mmap` regions
+~~~~~~~~~~~~~~
+
+An ``mmap_region`` is an abstract, concise way to represent a memory region to
+map. It is one of the key interfaces to the library. It is identified by:
+
+- its physical base address;
+- its virtual base address;
+- its size;
+- its attributes;
+- its mapping granularity (optional).
+
+See the ``struct mmap_region`` type in ``xlat_tables_v2.h``.
+
+The user usually provides a list of such mmap regions to map and lets the
+library transpose that in a set of translation tables. As a result, the library
+might create new translation tables, update or split existing ones.
+
+The region attributes specify the type of memory (for example device or cached
+normal memory) as well as the memory access permissions (read-only or
+read-write, executable or not, secure or non-secure, and so on). In the case of
+the EL1&0 translation regime, the attributes also specify whether the region is
+a User region (EL0) or Privileged region (EL1). See the ``MT_xxx`` definitions
+in ``xlat_tables_v2.h``. Note that for the EL1&0 translation regime the Execute
+Never attribute is set simultaneously for both EL1 and EL0.
+
+The granularity controls the translation table level to go down to when mapping
+the region. For example, assuming the MMU has been configured to use a 4KB
+granule size, the library might map a 2MB memory region using either of the two
+following options:
+
+- using a single level-2 translation table entry;
+- using a level-2 intermediate entry to a level-3 translation table (which
+  contains 512 entries, each mapping 4KB).
+
+The first solution potentially requires less translation tables, hence
+potentially less memory.  However, if part of this 2MB region is later remapped
+with different memory attributes, the library might need to split the existing
+page tables to refine the mappings. If a single level-2 entry has been used
+here, a level-3 table will need to be allocated on the fly and the level-2
+modified to point to this new level-3 table. This has a performance cost at
+run-time.
+
+If the user knows upfront that such a remapping operation is likely to happen
+then they might enforce a 4KB mapping granularity for this 2MB region from the
+beginning; remapping some of these 4KB pages on the fly then becomes a
+lightweight operation.
+
+The region's granularity is an optional field; if it is not specified the
+library will choose the mapping granularity for this region as it sees fit (more
+details can be found in `The memory mapping algorithm`_ section below).
+
+The MPU library also uses ``struct mmap_region`` to specify translations, but
+the MPU's translations are limited to specification of valid addresses and
+access permissions.  If the requested virtual and physical addresses mismatch
+the system will panic. Being register-based for deterministic memory-reference
+timing, the MPU hardware does not involve memory-resident translation tables.
+
+Currently, the MPU library is also limited to MPU translation at EL2 with no
+MMU translation at other ELs.  These limitations, however, are expected to be
+overcome in future library versions.
+
+Translation Context
+~~~~~~~~~~~~~~~~~~~
+
+The library can create or modify translation tables pertaining to a different
+translation regime than the exception level the library code is executing at.
+For example, the library might be used by EL3 software (for instance BL31) to
+create translation tables pertaining to the S-EL1&0 translation regime.
+
+This flexibility comes from the use of *translation contexts*. A *translation
+context* constitutes the superset of information used by the library to track
+the status of a set of translation tables for a given translation regime.
+
+The library internally allocates a default translation context, which pertains
+to the translation regime of the current exception level. Additional contexts
+may be explicitly allocated and initialized using the
+``REGISTER_XLAT_CONTEXT()`` macro. Separate APIs are provided to act either on
+the default translation context or on an alternative one.
+
+To register a translation context, the user must provide the library with the
+following information:
+
+* A name.
+
+  The resulting translation context variable will be called after this name, to
+  which ``_xlat_ctx`` is appended. For example, if the macro name parameter is
+  ``foo``, the context variable name will be ``foo_xlat_ctx``.
+
+* The maximum number of `mmap` regions to map.
+
+  Should account for both static and dynamic regions, if applicable.
+
+* The number of sub-translation tables to allocate.
+
+  Number of translation tables to statically allocate for this context,
+  excluding the initial lookup level translation table, which is always
+  allocated. For example, if the initial lookup level is 1, this parameter would
+  specify the number of level-2 and level-3 translation tables to pre-allocate
+  for this context.
+
+* The size of the virtual address space.
+
+  Size in bytes of the virtual address space to map using this context. This
+  will incidentally determine the number of entries in the initial lookup level
+  translation table : the library will allocate as many entries as is required
+  to map the entire virtual address space.
+
+* The size of the physical address space.
+
+  Size in bytes of the physical address space to map using this context.
+
+The default translation context is internally initialized using information
+coming (for the most part) from platform-specific defines:
+
+- name: hard-coded to ``tf`` ; hence the name of the default context variable is
+  ``tf_xlat_ctx``;
+- number of `mmap` regions: ``MAX_MMAP_REGIONS``;
+- number of sub-translation tables: ``MAX_XLAT_TABLES``;
+- size of the virtual address space: ``PLAT_VIRT_ADDR_SPACE_SIZE``;
+- size of the physical address space: ``PLAT_PHY_ADDR_SPACE_SIZE``.
+
+Please refer to the :ref:`Porting Guide` for more details about these macros.
+
+
+Static and dynamic memory regions
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The library optionally supports dynamic memory mapping. This feature may be
+enabled using the ``PLAT_XLAT_TABLES_DYNAMIC`` platform build flag.
+
+When dynamic memory mapping is enabled, the library categorises mmap regions as
+*static* or *dynamic*.
+
+- *Static regions* are fixed for the lifetime of the system. They can only be
+  added early on, before the translation tables are created and populated. They
+  cannot be removed afterwards.
+
+- *Dynamic regions* can be added or removed any time.
+
+When the dynamic memory mapping feature is disabled, only static regions exist.
+
+The dynamic memory mapping feature may be used to map and unmap transient memory
+areas. This is useful when the user needs to access some memory for a fixed
+period of time, after which the memory may be discarded and reclaimed. For
+example, a memory region that is only required at boot time while the system is
+initializing, or to temporarily share a memory buffer between the normal world
+and trusted world. Note that it is up to the caller to ensure that these regions
+are not accessed concurrently while the regions are being added or removed.
+
+Although this feature provides some level of dynamic memory allocation, this
+does not allow dynamically allocating an arbitrary amount of memory at an
+arbitrary memory location. The user is still required to declare at compile-time
+the limits of these allocations ; the library will deny any mapping request that
+does not fit within this pre-allocated pool of memory.
+
+
+Library APIs
+------------
+
+The external APIs exposed by this library are declared and documented in the
+``xlat_tables_v2.h`` header file. This should be the reference point for
+getting information about the usage of the different APIs this library
+provides. This section just provides some extra details and clarifications.
+
+Although the ``mmap_region`` structure is a publicly visible type, it is not
+recommended to populate these structures by hand. Instead, wherever APIs expect
+function arguments of type ``mmap_region_t``, these should be constructed using
+the ``MAP_REGION*()`` family of helper macros. This is to limit the risk of
+compatibility breaks, should the ``mmap_region`` structure type evolve in the
+future.
+
+The ``MAP_REGION()`` and ``MAP_REGION_FLAT()`` macros do not allow specifying a
+mapping granularity, which leaves the library implementation free to choose
+it. However, in cases where a specific granularity is required, the
+``MAP_REGION2()`` macro might be used instead. Using ``MAP_REGION_FLAT()`` only
+to define regions for the MPU library is strongly recommended.
+
+As explained earlier in this document, when the dynamic mapping feature is
+disabled, there is no notion of dynamic regions. Conceptually, there are only
+static regions. For this reason (and to retain backward compatibility with the
+version 1 of the library), the APIs that map static regions do not embed the
+word *static* in their functions names (for example ``mmap_add_region()``), in
+contrast with the dynamic regions APIs (for example
+``mmap_add_dynamic_region()``).
+
+Although the definition of static and dynamic regions is not based on the state
+of the MMU, the two are still related in some way. Static regions can only be
+added before ``init_xlat_tables()`` is called and ``init_xlat_tables()`` must be
+called while the MMU is still off. As a result, static regions cannot be added
+once the MMU has been enabled. Dynamic regions can be added with the MMU on or
+off. In practice, the usual call flow would look like this:
+
+#. The MMU is initially off.
+
+#. Add some static regions, add some dynamic regions.
+
+#. Initialize translation tables based on the list of mmap regions (using one of
+   the ``init_xlat_tables*()`` APIs).
+
+#. At this point, it is no longer possible to add static regions. Dynamic
+   regions can still be added or removed.
+
+#. Enable the MMU.
+
+#. Dynamic regions can continue to be added or removed.
+
+Because static regions are added early on at boot time and are all in the
+control of the platform initialization code, the ``mmap_add*()`` family of APIs
+are not expected to fail. They do not return any error code.
+
+Nonetheless, these APIs will check upfront whether the region can be
+successfully added before updating the translation context structure. If the
+library detects that there is insufficient memory to meet the request, or that
+the new region will overlap another one in an invalid way, or if any other
+unexpected error is encountered, they will print an error message on the UART.
+Additionally, when asserts are enabled (typically in debug builds), an assertion
+will be triggered. Otherwise, the function call will just return straight away,
+without adding the offending memory region.
+
+
+Library limitations
+-------------------
+
+Dynamic regions are not allowed to overlap each other. Static regions are
+allowed to overlap as long as one of them is fully contained inside the other
+one. This is allowed for backwards compatibility with the previous behaviour in
+the version 1 of the library.
+
+
+Implementation details
+----------------------
+
+Code structure
+~~~~~~~~~~~~~~
+
+The library is divided into 4 modules:
+
+- **Core module**
+
+  Provides the main functionality of the library, such as the initialization of
+  translation tables contexts and mapping/unmapping memory regions. This module
+  provides functions such as ``mmap_add_region_ctx`` that let the caller specify
+  the translation tables context affected by them.
+
+  See ``xlat_tables_core.c``.
+
+- **Active context module**
+
+  Instantiates the context that is used by the current BL image and provides
+  helpers to manipulate it, abstracting it from the rest of the code.
+  This module provides functions such as ``mmap_add_region``, that directly
+  affect the BL image using them.
+
+  See ``xlat_tables_context.c``.
+
+- **Utilities module**
+
+  Provides additional functionality like debug print of the current state of the
+  translation tables and helpers to query memory attributes and to modify them.
+
+  See ``xlat_tables_utils.c``.
+
+- **Architectural module**
+
+  Provides functions that are dependent on the current execution state
+  (AArch32/AArch64), such as the functions used for TLB invalidation, setup the
+  MMU, or calculate the Physical Address Space size. They do not need a
+  translation context to work on.
+
+  See ``aarch32/xlat_tables_arch.c`` and ``aarch64/xlat_tables_arch.c``.
+
+From mmap regions to translation tables
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+A translation context contains a list of ``mmap_region_t``, which holds the
+information of all the regions that are mapped at any given time. Whenever there
+is a request to map (resp. unmap) a memory region, it is added to (resp. removed
+from) the ``mmap_region_t`` list.
+
+The mmap regions list is a conceptual way to represent the memory layout. At
+some point, the library has to convert this information into actual translation
+tables to program into the MMU.
+
+Before the ``init_xlat_tables()`` API is called, the library only acts on the
+mmap regions list. Adding a static or dynamic region at this point through one
+of the ``mmap_add*()`` APIs does not affect the translation tables in any way,
+they only get registered in the internal mmap region list. It is only when the
+user calls the ``init_xlat_tables()`` that the translation tables are populated
+in memory based on the list of mmap regions registered so far. This is an
+optimization that allows creation of the initial set of translation tables in
+one go, rather than having to edit them every time while the MMU is disabled.
+
+After the ``init_xlat_tables()`` API has been called, only dynamic regions can
+be added. Changes to the translation tables (as well as the mmap regions list)
+will take effect immediately.
+
+The memory mapping algorithm
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The mapping function is implemented as a recursive algorithm. It is however
+bound by the level of depth of the translation tables (the Armv8-A architecture
+allows up to 4 lookup levels).
+
+By default [#granularity]_, the algorithm will attempt to minimize the
+number of translation tables created to satisfy the user's request. It will
+favour mapping a region using the biggest possible blocks, only creating a
+sub-table if it is strictly necessary. This is to reduce the memory footprint of
+the firmware.
+
+The most common reason for needing a sub-table is when a specific mapping
+requires a finer granularity. Misaligned regions also require a finer
+granularity than what the user may had originally expected, using a lot more
+memory than expected. The reason is that all levels of translation are
+restricted to address translations of the same granularity as the size of the
+blocks of that level.  For example, for a 4 KiB page size, a level 2 block entry
+can only translate up to a granularity of 2 MiB. If the Physical Address is not
+aligned to 2 MiB then additional level 3 tables are also needed.
+
+Note that not every translation level allows any type of descriptor. Depending
+on the page size, levels 0 and 1 of translation may only allow table
+descriptors. If a block entry could be able to describe a translation, but that
+level does not allow block descriptors, a table descriptor will have to be used
+instead, as well as additional tables at the next level.
+
+|Alignment Example|
+
+The mmap regions are sorted in a way that simplifies the code that maps
+them. Even though this ordering is only strictly needed for overlapping static
+regions, it must also be applied for dynamic regions to maintain a consistent
+order of all regions at all times. As each new region is mapped, existing
+entries in the translation tables are checked to ensure consistency. Please
+refer to the comments in the source code of the core module for more details
+about the sorting algorithm in use.
+
+This mapping algorithm does not apply to the MPU library, since the MPU hardware
+directly maps regions by "base" and "limit" (bottom and top) addresses.
+
+TLB maintenance operations
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The library takes care of performing TLB maintenance operations when required.
+For example, when the user requests removing a dynamic region, the library
+invalidates all TLB entries associated to that region to ensure that these
+changes are visible to subsequent execution, including speculative execution,
+that uses the changed translation table entries.
+
+A counter-example is the initialization of translation tables. In this case,
+explicit TLB maintenance is not required. The Armv8-A architecture guarantees
+that all TLBs are disabled from reset and their contents have no effect on
+address translation at reset [#tlb-reset-ref]_. Therefore, the TLBs invalidation
+is deferred to the ``enable_mmu*()`` family of functions, just before the MMU is
+turned on.
+
+Regarding enabling and disabling memory management, for the MPU library, to
+reduce confusion, calls to enable or disable the MPU use ``mpu`` in their names
+in place of ``mmu``. For example, the ``enable_mmu_el2()`` call is changed to
+``enable_mpu_el2()``.
+
+TLB invalidation is not required when adding dynamic regions either. Dynamic
+regions are not allowed to overlap existing memory region. Therefore, if the
+dynamic mapping request is deemed legitimate, it automatically concerns memory
+that was not mapped in this translation regime and the library will have
+initialized its corresponding translation table entry to an invalid
+descriptor. Given that the TLBs are not architecturally permitted to hold any
+invalid translation table entry [#tlb-no-invalid-entry]_, this means that this
+mapping cannot be cached in the TLBs.

+Alternative Boot Flows
+======================
+
+EL3 payloads alternative boot flow
+----------------------------------
+
+On a pre-production system, the ability to execute arbitrary, bare-metal code at
+the highest exception level is required. It allows full, direct access to the
+hardware, for example to run silicon soak tests.
+
+Although it is possible to implement some baremetal secure firmware from
+scratch, this is a complex task on some platforms, depending on the level of
+configuration required to put the system in the expected state.
+
+Rather than booting a baremetal application, a possible compromise is to boot
+``EL3 payloads`` through TF-A instead. This is implemented as an alternative
+boot flow, where a modified BL2 boots an EL3 payload, instead of loading the
+other BL images and passing control to BL31. It reduces the complexity of
+developing EL3 baremetal code by:
+
+-  putting the system into a known architectural state;
+-  taking care of platform secure world initialization;
+-  loading the SCP_BL2 image if required by the platform.
+
+When booting an EL3 payload on Arm standard platforms, the configuration of the
+TrustZone controller is simplified such that only region 0 is enabled and is
+configured to permit secure access only. This gives full access to the whole
+DRAM to the EL3 payload.
+
+The system is left in the same state as when entering BL31 in the default boot
+flow. In particular:
+
+-  Running in EL3;
+-  Current state is AArch64;
+-  Little-endian data access;
+-  All exceptions disabled;
+-  MMU disabled;
+-  Caches disabled.
+
+.. _alt_boot_flows_el3_payload:
+
+Booting an EL3 payload
+~~~~~~~~~~~~~~~~~~~~~~
+
+The EL3 payload image is a standalone image and is not part of the FIP. It is
+not loaded by TF-A. Therefore, there are 2 possible scenarios:
+
+-  The EL3 payload may reside in non-volatile memory (NVM) and execute in
+   place. In this case, booting it is just a matter of specifying the right
+   address in NVM through ``EL3_PAYLOAD_BASE`` when building TF-A.
+
+-  The EL3 payload needs to be loaded in volatile memory (e.g. DRAM) at
+   run-time.
+
+To help in the latter scenario, the ``SPIN_ON_BL1_EXIT=1`` build option can be
+used. The infinite loop that it introduces in BL1 stops execution at the right
+moment for a debugger to take control of the target and load the payload (for
+example, over JTAG).
+
+It is expected that this loading method will work in most cases, as a debugger
+connection is usually available in a pre-production system. The user is free to
+use any other platform-specific mechanism to load the EL3 payload, though.
+
+
+Preloaded BL33 alternative boot flow
+------------------------------------
+
+Some platforms have the ability to preload BL33 into memory instead of relying
+on TF-A to load it. This may simplify packaging of the normal world code and
+improve performance in a development environment. When secure world cold boot
+is complete, TF-A simply jumps to a BL33 base address provided at build time.
+
+For this option to be used, the ``PRELOADED_BL33_BASE`` build option has to be
+used when compiling TF-A. For example, the following command will create a FIP
+without a BL33 and prepare to jump to a BL33 image loaded at address
+0x80000000:
+
+.. code:: shell
+
+    make PRELOADED_BL33_BASE=0x80000000 PLAT=fvp all fip

+Authentication Framework & Chain of Trust
+=========================================
+
+The aim of this document is to describe the authentication framework
+implemented in Trusted Firmware-A (TF-A). This framework fulfills the
+following requirements:
+
+#. It should be possible for a platform port to specify the Chain of Trust in
+   terms of certificate hierarchy and the mechanisms used to verify a
+   particular image/certificate.
+
+#. The framework should distinguish between:
+
+   -  The mechanism used to encode and transport information, e.g. DER encoded
+      X.509v3 certificates to ferry Subject Public Keys, hashes and non-volatile
+      counters.
+
+   -  The mechanism used to verify the transported information i.e. the
+      cryptographic libraries.
+
+The framework has been designed following a modular approach illustrated in the

+Framework design
+----------------
+
+This section describes some aspects of the framework design and the rationale
+behind them. These aspects are key to verify a Chain of Trust.
+
+Chain of Trust
+~~~~~~~~~~~~~~
+
+A CoT is basically a sequence of authentication images which usually starts with
+a root of trust and culminates in a single data image. The following diagram
+illustrates how this maps to a CoT for the BL31 image described in the
+`TBBR-Client specification`_.

+        DIAGRAM 2.
+
+The root of trust is usually a public key (ROTPK) that has been burnt in the
+platform and cannot be modified.
+
+Image types
+~~~~~~~~~~~
+
+Images in a CoT are categorised as authentication and data images. An
+authentication image contains information to authenticate a data image or
+another authentication image. A data image is usually a boot loader binary, but
+it could be any other data that requires authentication.
+
+Component responsibilities
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+For every image in a Chain of Trust, the following high level operations are
+performed to verify it:
+
+#. Allocate memory for the image either statically or at runtime.
+
+#. Identify the image and load it in the allocated memory.
+
+#. Check the integrity of the image as per its type.
+
+#. Authenticate the image as per the cryptographic algorithms used.
+
+#. If the image is an authentication image, extract the information that will
+   be used to authenticate the next image in the CoT.
+
+In Diagram 1, each component is responsible for one or more of these operations.
+The responsibilities are briefly described below.
+
+TF-A Generic code and IO framework (GEN/IO)
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+These components are responsible for initiating the authentication process for a
+particular image in BL1 or BL2. For each BL image that requires authentication,
+the Generic code asks recursively the Authentication module what is the parent
+image until either an authenticated image or the ROT is reached. Then the
+Generic code calls the IO framework to load the image and calls the
+Authentication module to authenticate it, following the CoT from ROT to Image.
+
+TF-A Platform Port (PP)
+^^^^^^^^^^^^^^^^^^^^^^^
+
+The platform is responsible for:
+
+#. Specifying the CoT for each image that needs to be authenticated. Details of
+   how a CoT can be specified by the platform are explained later. The platform
+   also specifies the authentication methods and the parsing method used for
+   each image.
+
+#. Statically allocating memory for each parameter in each image which is
+   used for verifying the CoT, e.g. memory for public keys, hashes etc.
+
+#. Providing the ROTPK or a hash of it.
+
+#. Providing additional information to the IPM to enable it to identify and
+   extract authentication parameters contained in an image, e.g. if the
+   parameters are stored as X509v3 extensions, the corresponding OID must be
+   provided.
+
+#. Fulfill any other memory requirements of the IPM and the CM (not currently
+   described in this document).
+
+#. Export functions to verify an image which uses an authentication method that
+   cannot be interpreted by the CM, e.g. if an image has to be verified using a
+   NV counter, then the value of the counter to compare with can only be
+   provided by the platform.
+
+#. Export a custom IPM if a proprietary image format is being used (described
+   later).
+
+Authentication Module (AM)
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+It is responsible for:
+
+#. Providing the necessary abstraction mechanisms to describe a CoT. Amongst
+   other things, the authentication and image parsing methods must be specified
+   by the PP in the CoT.
+
+#. Verifying the CoT passed by GEN by utilising functionality exported by the
+   PP, IPM and CM.
+
+#. Tracking which images have been verified. In case an image is a part of
+   multiple CoTs then it should be verified only once e.g. the Trusted World
+   Key Certificate in the TBBR-Client spec. contains information to verify
+   SCP_BL2, BL31, BL32 each of which have a separate CoT. (This
+   responsibility has not been described in this document but should be
+   trivial to implement).
+
+#. Reusing memory meant for a data image to verify authentication images e.g.
+   in the CoT described in Diagram 2, each certificate can be loaded and
+   verified in the memory reserved by the platform for the BL31 image. By the
+   time BL31 (the data image) is loaded, all information to authenticate it
+   will have been extracted from the parent image i.e. BL31 content
+   certificate. It is assumed that the size of an authentication image will
+   never exceed the size of a data image. It should be possible to verify this
+   at build time using asserts.
+
+Cryptographic Module (CM)
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The CM is responsible for providing an API to:
+
+#. Verify a digital signature.
+#. Verify a hash.
+
+The CM does not include any cryptography related code, but it relies on an
+external library to perform the cryptographic operations. A Crypto-Library (CL)
+linking the CM and the external library must be implemented. The following
+functions must be provided by the CL:
+
+.. code:: c
+
+    void (*init)(void);
+    int (*verify_signature)(void *data_ptr, unsigned int data_len,
+                            void *sig_ptr, unsigned int sig_len,
+                            void *sig_alg, unsigned int sig_alg_len,
+                            void *pk_ptr, unsigned int pk_len);
+    int (*verify_hash)(void *data_ptr, unsigned int data_len,
+                       void *digest_info_ptr, unsigned int digest_info_len);
+
+These functions are registered in the CM using the macro:
+
+.. code:: c
+
+    REGISTER_CRYPTO_LIB(_name, _init, _verify_signature, _verify_hash);
+
+``_name`` must be a string containing the name of the CL. This name is used for
+debugging purposes.
+
+Image Parser Module (IPM)
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The IPM is responsible for:
+
+#. Checking the integrity of each image loaded by the IO framework.
+#. Extracting parameters used for authenticating an image based upon a
+   description provided by the platform in the CoT descriptor.
+
+Images may have different formats (for example, authentication images could be
+x509v3 certificates, signed ELF files or any other platform specific format).
+The IPM allows to register an Image Parser Library (IPL) for every image format
+used in the CoT. This library must implement the specific methods to parse the
+image. The IPM obtains the image format from the CoT and calls the right IPL to
+check the image integrity and extract the authentication parameters.
+
+See Section "Describing the image parsing methods" for more details about the
+mechanism the IPM provides to define and register IPLs.
+
+Authentication methods
+~~~~~~~~~~~~~~~~~~~~~~
+
+The AM supports the following authentication methods:
+
+#. Hash
+#. Digital signature
+
+The platform may specify these methods in the CoT in case it decides to define
+a custom CoT instead of reusing a predefined one.
+
+If a data image uses multiple methods, then all the methods must be a part of
+the same CoT. The number and type of parameters are method specific. These
+parameters should be obtained from the parent image using the IPM.
+
+#. Hash
+
+   Parameters:
+
+   #. A pointer to data to hash
+   #. Length of the data
+   #. A pointer to the hash
+   #. Length of the hash
+
+   The hash will be represented by the DER encoding of the following ASN.1
+   type:
+
+   ::
+
+       DigestInfo ::= SEQUENCE {
+           digestAlgorithm  DigestAlgorithmIdentifier,
+           digest           Digest
+       }
+
+   This ASN.1 structure makes it possible to remove any assumption about the
+   type of hash algorithm used as this information accompanies the hash. This
+   should allow the Cryptography Library (CL) to support multiple hash
+   algorithm implementations.
+
+#. Digital Signature
+
+   Parameters:
+
+   #. A pointer to data to sign
+   #. Length of the data
+   #. Public Key Algorithm
+   #. Public Key value
+   #. Digital Signature Algorithm
+   #. Digital Signature value
+
+   The Public Key parameters will be represented by the DER encoding of the
+   following ASN.1 type:
+
+   ::
+
+       SubjectPublicKeyInfo  ::=  SEQUENCE  {
+           algorithm         AlgorithmIdentifier{PUBLIC-KEY,{PublicKeyAlgorithms}},
+           subjectPublicKey  BIT STRING  }
+
+   The Digital Signature Algorithm will be represented by the DER encoding of
+   the following ASN.1 types.
+
+   ::
+
+       AlgorithmIdentifier {ALGORITHM:IOSet } ::= SEQUENCE {
+           algorithm         ALGORITHM.&id({IOSet}),
+           parameters        ALGORITHM.&Type({IOSet}{@algorithm}) OPTIONAL
+       }
+
+   The digital signature will be represented by:
+
+   ::
+
+       signature  ::=  BIT STRING
+
+The authentication framework will use the image descriptor to extract all the
+information related to authentication.
+
+Specifying a Chain of Trust
+---------------------------
+
+A CoT can be described as a set of image descriptors linked together in a
+particular order. The order dictates the sequence in which they must be
+verified. Each image has a set of properties which allow the AM to verify it.
+These properties are described below.
+
+The PP is responsible for defining a single or multiple CoTs for a data image.
+Unless otherwise specified, the data structures described in the following
+sections are populated by the PP statically.
+
+Describing the image parsing methods
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The parsing method refers to the format of a particular image. For example, an
+authentication image that represents a certificate could be in the X.509v3
+format. A data image that represents a boot loader stage could be in raw binary
+or ELF format. The IPM supports three parsing methods. An image has to use one
+of the three methods described below. An IPL is responsible for interpreting a
+single parsing method. There has to be one IPL for every method used by the
+platform.
+
+#. Raw format: This format is effectively a nop as an image using this method
+   is treated as being in raw binary format e.g. boot loader images used by
+   TF-A. This method should only be used by data images.
+
+#. X509V3 method: This method uses industry standards like X.509 to represent
+   PKI certificates (authentication images). It is expected that open source
+   libraries will be available which can be used to parse an image represented
+   by this method. Such libraries can be used to write the corresponding IPL
+   e.g. the X.509 parsing library code in mbed TLS.
+
+#. Platform defined method: This method caters for platform specific
+   proprietary standards to represent authentication or data images. For
+   example, The signature of a data image could be appended to the data image
+   raw binary. A header could be prepended to the combined blob to specify the
+   extents of each component. The platform will have to implement the
+   corresponding IPL to interpret such a format.
+
+The following enum can be used to define these three methods.
+
+.. code:: c
+
+    typedef enum img_type_enum {
+        IMG_RAW,            /* Binary image */
+        IMG_PLAT,           /* Platform specific format */
+        IMG_CERT,           /* X509v3 certificate */
+        IMG_MAX_TYPES,
+    } img_type_t;
+
+An IPL must provide functions with the following prototypes:
+
+.. code:: c
+
+    void init(void);
+    int check_integrity(void *img, unsigned int img_len);
+    int get_auth_param(const auth_param_type_desc_t *type_desc,
+                          void *img, unsigned int img_len,
+                          void **param, unsigned int *param_len);
+
+An IPL for each type must be registered using the following macro:
+
+.. code:: c
+
+    REGISTER_IMG_PARSER_LIB(_type, _name, _init, _check_int, _get_param)
+
+-  ``_type``: one of the types described above.
+-  ``_name``: a string containing the IPL name for debugging purposes.
+-  ``_init``: initialization function pointer.
+-  ``_check_int``: check image integrity function pointer.
+-  ``_get_param``: extract authentication parameter function pointer.
+
+The ``init()`` function will be used to initialize the IPL.
+
+The ``check_integrity()`` function is passed a pointer to the memory where the
+image has been loaded by the IO framework and the image length. It should ensure
+that the image is in the format corresponding to the parsing method and has not
+been tampered with. For example, RFC-2459 describes a validation sequence for an
+X.509 certificate.
+
+The ``get_auth_param()`` function is passed a parameter descriptor containing
+information about the parameter (``type_desc`` and ``cookie``) to identify and
+extract the data corresponding to that parameter from an image. This data will
+be used to verify either the current or the next image in the CoT sequence.
+
+Each image in the CoT will specify the parsing method it uses. This information
+will be used by the IPM to find the right parser descriptor for the image.
+
+Describing the authentication method(s)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+As part of the CoT, each image has to specify one or more authentication methods
+which will be used to verify it. As described in the Section "Authentication
+methods", there are three methods supported by the AM.
+
+.. code:: c
+
+    typedef enum {
+        AUTH_METHOD_NONE,
+        AUTH_METHOD_HASH,
+        AUTH_METHOD_SIG,
+        AUTH_METHOD_NUM
+    } auth_method_type_t;
+
+The AM defines the type of each parameter used by an authentication method. It
+uses this information to:
+
+#. Specify to the ``get_auth_param()`` function exported by the IPM, which
+   parameter should be extracted from an image.
+
+#. Correctly marshall the parameters while calling the verification function
+   exported by the CM and PP.
+
+#. Extract authentication parameters from a parent image in order to verify a
+   child image e.g. to verify the certificate image, the public key has to be
+   obtained from the parent image.
+
+.. code:: c
+
+    typedef enum {
+        AUTH_PARAM_NONE,
+        AUTH_PARAM_RAW_DATA,        /* Raw image data */
+        AUTH_PARAM_SIG,         /* The image signature */
+        AUTH_PARAM_SIG_ALG,     /* The image signature algorithm */
+        AUTH_PARAM_HASH,        /* A hash (including the algorithm) */
+        AUTH_PARAM_PUB_KEY,     /* A public key */
+    } auth_param_type_t;
+
+The AM defines the following structure to identify an authentication parameter
+required to verify an image.
+
+.. code:: c
+
+    typedef struct auth_param_type_desc_s {
+        auth_param_type_t type;
+        void *cookie;
+    } auth_param_type_desc_t;
+
+``cookie`` is used by the platform to specify additional information to the IPM
+which enables it to uniquely identify the parameter that should be extracted
+from an image. For example, the hash of a BL3x image in its corresponding
+content certificate is stored in an X509v3 custom extension field. An extension
+field can only be identified using an OID. In this case, the ``cookie`` could
+contain the pointer to the OID defined by the platform for the hash extension
+field while the ``type`` field could be set to ``AUTH_PARAM_HASH``. A value of 0 for
+the ``cookie`` field means that it is not used.
+
+For each method, the AM defines a structure with the parameters required to
+verify the image.
+
+.. code:: c
+
+    /*
+     * Parameters for authentication by hash matching
+     */
+    typedef struct auth_method_param_hash_s {
+        auth_param_type_desc_t *data;   /* Data to hash */
+        auth_param_type_desc_t *hash;   /* Hash to match with */
+    } auth_method_param_hash_t;
+
+    /*
+     * Parameters for authentication by signature
+     */
+    typedef struct auth_method_param_sig_s {
+        auth_param_type_desc_t *pk; /* Public key */
+        auth_param_type_desc_t *sig;    /* Signature to check */
+        auth_param_type_desc_t *alg;    /* Signature algorithm */
+        auth_param_type_desc_t *tbs;    /* Data signed */
+    } auth_method_param_sig_t;
+
+The AM defines the following structure to describe an authentication method for
+verifying an image
+
+.. code:: c
+
+    /*
+     * Authentication method descriptor
+     */
+    typedef struct auth_method_desc_s {
+        auth_method_type_t type;
+        union {
+            auth_method_param_hash_t hash;
+            auth_method_param_sig_t sig;
+        } param;
+    } auth_method_desc_t;
+
+Using the method type specified in the ``type`` field, the AM finds out what field
+needs to access within the ``param`` union.
+
+Storing Authentication parameters
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+A parameter described by ``auth_param_type_desc_t`` to verify an image could be
+obtained from either the image itself or its parent image. The memory allocated
+for loading the parent image will be reused for loading the child image. Hence
+parameters which are obtained from the parent for verifying a child image need
+to have memory allocated for them separately where they can be stored. This
+memory must be statically allocated by the platform port.
+
+The AM defines the following structure to store the data corresponding to an
+authentication parameter.
+
+.. code:: c
+
+    typedef struct auth_param_data_desc_s {
+        void *auth_param_ptr;
+        unsigned int auth_param_len;
+    } auth_param_data_desc_t;
+
+The ``auth_param_ptr`` field is initialized by the platform. The ``auth_param_len``
+field is used to specify the length of the data in the memory.
+
+For parameters that can be obtained from the child image itself, the IPM is
+responsible for populating the ``auth_param_ptr`` and ``auth_param_len`` fields
+while executing the ``img_get_auth_param()`` function.
+
+The AM defines the following structure to enable an image to describe the
+parameters that should be extracted from it and used to verify the next image
+(child) in a CoT.
+
+.. code:: c
+
+    typedef struct auth_param_desc_s {
+        auth_param_type_desc_t type_desc;
+        auth_param_data_desc_t data;
+    } auth_param_desc_t;
+
+Describing an image in a CoT
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+An image in a CoT is a consolidation of the following aspects of a CoT described
+above.
+
+#. A unique identifier specified by the platform which allows the IO framework
+   to locate the image in a FIP and load it in the memory reserved for the data
+   image in the CoT.
+
+#. A parsing method which is used by the AM to find the appropriate IPM.
+
+#. Authentication methods and their parameters as described in the previous
+   section. These are used to verify the current image.
+
+#. Parameters which are used to verify the next image in the current CoT. These
+   parameters are specified only by authentication images and can be extracted
+   from the current image once it has been verified.
+
+The following data structure describes an image in a CoT.
+

+A CoT is defined as an array of pointers to ``auth_image_desc_t`` structures
+linked together by the ``parent`` field. Those nodes with no parent must be
+authenticated using the ROTPK stored in the platform.
+
+Implementation example
+----------------------
+
+This section is a detailed guide explaining a trusted boot implementation using
+the authentication framework. This example corresponds to the Applicative
+Functional Mode (AFM) as specified in the TBBR-Client document. It is
+recommended to read this guide along with the source code.
+
+The TBBR CoT
+~~~~~~~~~~~~
+
+CoT specific to BL1 and BL2 can be found in ``drivers/auth/tbbr/tbbr_cot_bl1.c``
+and ``drivers/auth/tbbr/tbbr_cot_bl2.c`` respectively. The common CoT used across
+BL1 and BL2 can be found in ``drivers/auth/tbbr/tbbr_cot_common.c``.
+This CoT consists of an array of pointers to image descriptors and it is
+registered in the framework using the macro ``REGISTER_COT(cot_desc)``, where
+``cot_desc`` must be the name of the array (passing a pointer or any other
+type of indirection will cause the registration process to fail).
+
+The number of images participating in the boot process depends on the CoT.
+There is, however, a minimum set of images that are mandatory in TF-A and thus
+all CoTs must present:
+
+-  ``BL2``
+-  ``SCP_BL2`` (platform specific)
+-  ``BL31``
+-  ``BL32`` (optional)
+-  ``BL33``
+
+The TBBR specifies the additional certificates that must accompany these images
+for a proper authentication. Details about the TBBR CoT may be found in the
+:ref:`Trusted Board Boot` document.
+
+Following the :ref:`Porting Guide`, a platform must provide unique
+identifiers for all the images and certificates that will be loaded during the
+boot process. If a platform is using the TBBR as a reference for trusted boot,
+these identifiers can be obtained from ``include/common/tbbr/tbbr_img_def.h``.
+Arm platforms include this file in ``include/plat/arm/common/arm_def.h``. Other
+platforms may also include this file or provide their own identifiers.
+
+**Important**: the authentication module uses these identifiers to index the
+CoT array, so the descriptors location in the array must match the identifiers.
+
+Each image descriptor must specify:
+
+-  ``img_id``: the corresponding image unique identifier defined by the platform.
+-  ``img_type``: the image parser module uses the image type to call the proper
+   parsing library to check the image integrity and extract the required
+   authentication parameters. Three types of images are currently supported:
+
+   -  ``IMG_RAW``: image is a raw binary. No parsing functions are available,
+      other than reading the whole image.
+   -  ``IMG_PLAT``: image format is platform specific. The platform may use this
+      type for custom images not directly supported by the authentication
+      framework.
+   -  ``IMG_CERT``: image is an x509v3 certificate.
+
+-  ``parent``: pointer to the parent image descriptor. The parent will contain
+   the information required to authenticate the current image. If the parent
+   is NULL, the authentication parameters will be obtained from the platform
+   (i.e. the BL2 and Trusted Key certificates are signed with the ROT private
+   key, whose public part is stored in the platform).
+-  ``img_auth_methods``: this points to an array which defines the
+   authentication methods that must be checked to consider an image
+   authenticated. Each method consists of a type and a list of parameter
+   descriptors. A parameter descriptor consists of a type and a cookie which
+   will point to specific information required to extract that parameter from
+   the image (i.e. if the parameter is stored in an x509v3 extension, the
+   cookie will point to the extension OID). Depending on the method type, a
+   different number of parameters must be specified. This pointer should not be
+   NULL.
+   Supported methods are:
+
+   -  ``AUTH_METHOD_HASH``: the hash of the image must match the hash extracted
+      from the parent image. The following parameter descriptors must be
+      specified:
+
+      -  ``data``: data to be hashed (obtained from current image)
+      -  ``hash``: reference hash (obtained from parent image)
+
+   -  ``AUTH_METHOD_SIG``: the image (usually a certificate) must be signed with
+      the private key whose public part is extracted from the parent image (or
+      the platform if the parent is NULL). The following parameter descriptors
+      must be specified:
+
+      -  ``pk``: the public key (obtained from parent image)
+      -  ``sig``: the digital signature (obtained from current image)
+      -  ``alg``: the signature algorithm used (obtained from current image)
+      -  ``data``: the data to be signed (obtained from current image)
+
+-  ``authenticated_data``: this array pointer indicates what authentication
+   parameters must be extracted from an image once it has been authenticated.
+   Each parameter consists of a parameter descriptor and the buffer
+   address/size to store the parameter. The CoT is responsible for allocating
+   the required memory to store the parameters. This pointer may be NULL.
+
+In the ``tbbr_cot*.c`` file, a set of buffers are allocated to store the parameters
+extracted from the certificates. In the case of the TBBR CoT, these parameters
+are hashes and public keys. In DER format, an RSA-4096 public key requires 550
+bytes, and a hash requires 51 bytes. Depending on the CoT and the authentication
+process, some of the buffers may be reused at different stages during the boot.
+
+Next in that file, the parameter descriptors are defined. These descriptors will
+be used to extract the parameter data from the corresponding image.
+

+                            }
+                    }
+            }
+    };
+
+The **Trusted Key certificate** is signed with the ROT private key and contains
+the Trusted World public key and the Non-Trusted World public key as x509v3
+extensions. This must be specified in the image descriptor using the
+``img_auth_methods`` and ``authenticated_data`` arrays, respectively.
+
+The Trusted Key certificate is authenticated by checking its digital signature
+using the ROTPK. Four parameters are required to check a signature: the public
+key, the algorithm, the signature and the data that has been signed. Therefore,
+four parameter descriptors must be specified with the authentication method:
+
+-  ``subject_pk``: parameter descriptor of type ``AUTH_PARAM_PUB_KEY``. This type
+   is used to extract a public key from the parent image. If the cookie is an
+   OID, the key is extracted from the corresponding x509v3 extension. If the
+   cookie is NULL, the subject public key is retrieved. In this case, because
+   the parent image is NULL, the public key is obtained from the platform
+   (this key will be the ROTPK).
+-  ``sig``: parameter descriptor of type ``AUTH_PARAM_SIG``. It is used to extract
+   the signature from the certificate.
+-  ``sig_alg``: parameter descriptor of type ``AUTH_PARAM_SIG``. It is used to
+   extract the signature algorithm from the certificate.
+-  ``raw_data``: parameter descriptor of type ``AUTH_PARAM_RAW_DATA``. It is used
+   to extract the data to be signed from the certificate.
+
+Once the signature has been checked and the certificate authenticated, the
+Trusted World public key needs to be extracted from the certificate. A new entry
+is created in the ``authenticated_data`` array for that purpose. In that entry,
+the corresponding parameter descriptor must be specified along with the buffer
+address to store the parameter value. In this case, the ``trusted_world_pk``
+descriptor is used to extract the public key from an x509v3 extension with OID
+``TRUSTED_WORLD_PK_OID``. The BL31 key certificate will use this descriptor as
+parameter in the signature authentication method. The key is stored in the
+``trusted_world_pk_buf`` buffer.
+
+The **BL31 Key certificate** is authenticated by checking its digital signature
+using the Trusted World public key obtained previously from the Trusted Key
+certificate. In the image descriptor, we specify a single authentication method
+by signature whose public key is the ``trusted_world_pk``. Once this certificate
+has been authenticated, we have to extract the BL31 public key, stored in the
+extension specified by ``soc_fw_content_pk``. This key will be copied to the
+``content_pk_buf`` buffer.
+
+The **BL31 certificate** is authenticated by checking its digital signature
+using the BL31 public key obtained previously from the BL31 Key certificate.
+We specify the authentication method using ``soc_fw_content_pk`` as public key.
+After authentication, we need to extract the BL31 hash, stored in the extension
+specified by ``soc_fw_hash``. This hash will be copied to the
+``soc_fw_hash_buf`` buffer.
+
+The **BL31 image** is authenticated by calculating its hash and matching it
+with the hash obtained from the BL31 certificate. The image descriptor contains
+a single authentication method by hash. The parameters to the hash method are
+the reference hash, ``soc_fw_hash``, and the data to be hashed. In this case,
+it is the whole image, so we specify ``raw_data``.
+
+The image parser library
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+The image parser module relies on libraries to check the image integrity and
+extract the authentication parameters. The number and type of parser libraries
+depend on the images used in the CoT. Raw images do not need a library, so
+only an x509v3 library is required for the TBBR CoT.
+
+Arm platforms will use an x509v3 library based on mbed TLS. This library may be
+found in ``drivers/auth/mbedtls/mbedtls_x509_parser.c``. It exports three
+functions:
+
+.. code:: c
+
+    void init(void);
+    int check_integrity(void *img, unsigned int img_len);
+    int get_auth_param(const auth_param_type_desc_t *type_desc,
+                       void *img, unsigned int img_len,
+                       void **param, unsigned int *param_len);
+
+The library is registered in the framework using the macro
+``REGISTER_IMG_PARSER_LIB()``. Each time the image parser module needs to access
+an image of type ``IMG_CERT``, it will call the corresponding function exported
+in this file.
+
+The build system must be updated to include the corresponding library and
+mbed TLS sources. Arm platforms use the ``arm_common.mk`` file to pull the
+sources.
+
+The cryptographic library
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The cryptographic module relies on a library to perform the required operations,
+i.e. verify a hash or a digital signature. Arm platforms will use a library
+based on mbed TLS, which can be found in
+``drivers/auth/mbedtls/mbedtls_crypto.c``. This library is registered in the
+authentication framework using the macro ``REGISTER_CRYPTO_LIB()`` and exports
+four functions:
+
+.. code:: c
+
+    void init(void);
+    int verify_signature(void *data_ptr, unsigned int data_len,
+                         void *sig_ptr, unsigned int sig_len,
+                         void *sig_alg, unsigned int sig_alg_len,
+                         void *pk_ptr, unsigned int pk_len);
+    int verify_hash(void *data_ptr, unsigned int data_len,
+                    void *digest_info_ptr, unsigned int digest_info_len);
+    int auth_decrypt(enum crypto_dec_algo dec_algo, void *data_ptr,
+                     size_t len, const void *key, unsigned int key_len,
+                     unsigned int key_flags, const void *iv,
+                     unsigned int iv_len, const void *tag,
+                     unsigned int tag_len)
+
+The mbedTLS library algorithm support is configured by both the
+``TF_MBEDTLS_KEY_ALG`` and ``TF_MBEDTLS_KEY_SIZE`` variables.
+
+-  ``TF_MBEDTLS_KEY_ALG`` can take in 3 values: `rsa`, `ecdsa` or `rsa+ecdsa`.
+   This variable allows the Makefile to include the corresponding sources in
+   the build for the various algorithms. Setting the variable to `rsa+ecdsa`
+   enables support for both rsa and ecdsa algorithms in the mbedTLS library.
+
+-  ``TF_MBEDTLS_KEY_SIZE`` sets the supported RSA key size for TFA. Valid values
+   include 1024, 2048, 3072 and 4096.
+
+-  ``TF_MBEDTLS_USE_AES_GCM`` enables the authenticated decryption support based
+   on AES-GCM algorithm. Valid values are 0 and 1.
+
+.. note::
+   If code size is a concern, the build option ``MBEDTLS_SHA256_SMALLER`` can
+   be defined in the platform Makefile. It will make mbed TLS use an
+   implementation of SHA-256 with smaller memory footprint (~1.5 KB less) but
+   slower (~30%).

+Arm CPU Specific Build Macros
+=============================
+
+This document describes the various build options present in the CPU specific
+operations framework to enable errata workarounds and to enable optimizations
+for a specific CPU on a platform.
+
+Security Vulnerability Workarounds
+----------------------------------
+
+TF-A exports a series of build flags which control which security
+vulnerability workarounds should be applied at runtime.
+
+-  ``WORKAROUND_CVE_2017_5715``: Enables the security workaround for
+   `CVE-2017-5715`_. This flag can be set to 0 by the platform if none
+   of the PEs in the system need the workaround. Setting this flag to 0 provides
+   no performance benefit for non-affected platforms, it just helps to comply
+   with the recommendation in the spec regarding workaround discovery.
+   Defaults to 1.
+
+-  ``WORKAROUND_CVE_2018_3639``: Enables the security workaround for
+   `CVE-2018-3639`_. Defaults to 1. The TF-A project recommends to keep
+   the default value of 1 even on platforms that are unaffected by
+   CVE-2018-3639, in order to comply with the recommendation in the spec
+   regarding workaround discovery.
+
+-  ``DYNAMIC_WORKAROUND_CVE_2018_3639``: Enables dynamic mitigation for
+   `CVE-2018-3639`_. This build option should be set to 1 if the target
+   platform contains at least 1 CPU that requires dynamic mitigation.
+   Defaults to 0.
+
+-  ``WORKAROUND_CVE_2022_23960``: Enables mitigation for `CVE-2022-23960`_.
+   This build option should be set to 1 if the target platform contains at
+   least 1 CPU that requires this mitigation. Defaults to 1.

+
+CPU Errata Workarounds
+----------------------
+
+TF-A exports a series of build flags which control the errata workarounds that
+are applied to each CPU by the reset handler. The errata details can be found
+in the CPU specific errata documents published by Arm:
+
+-  `Cortex-A53 MPCore Software Developers Errata Notice`_
+-  `Cortex-A57 MPCore Software Developers Errata Notice`_
+-  `Cortex-A72 MPCore Software Developers Errata Notice`_
+
+The errata workarounds are implemented for a particular revision or a set of
+processor revisions. This is checked by the reset handler at runtime. Each
+errata workaround is identified by its ``ID`` as specified in the processor's
+errata notice document. The format of the define used to enable/disable the
+errata workaround is ``ERRATA_<Processor name>_<ID>``, where the ``Processor name``
+is for example ``A57`` for the ``Cortex_A57`` CPU.
+
+Refer to :ref:`firmware_design_cpu_errata_reporting` for information on how to
+write errata workaround functions.
+
+All workarounds are disabled by default. The platform is responsible for
+enabling these workarounds according to its requirement by defining the
+errata workaround build flags in the platform specific makefile. In case
+these workarounds are enabled for the wrong CPU revision then the errata
+workaround is not applied. In the DEBUG build, this is indicated by
+printing a warning to the crash console.
+
+In the current implementation, a platform which has more than 1 variant
+with different revisions of a processor has no runtime mechanism available
+for it to specify which errata workarounds should be enabled or not.
+
+The value of the build flags is 0 by default, that is, disabled. A value of 1
+will enable it.
+

+
+DSU Errata Workarounds
+----------------------
+
+Similar to CPU errata, TF-A also implements workarounds for DSU (DynamIQ
+Shared Unit) errata. The DSU errata details can be found in the respective Arm
+documentation:
+
+- `Arm DSU Software Developers Errata Notice`_.
+
+Each erratum is identified by an ``ID``, as defined in the DSU errata notice
+document. Thus, the build flags which enable/disable the errata workarounds
+have the format ``ERRATA_DSU_<ID>``. The implementation and application logic
+of DSU errata workarounds are similar to `CPU errata workarounds`_.
+
+For DSU errata, the following build flags are defined:
+
+-  ``ERRATA_DSU_798953``: This applies errata 798953 workaround for the
+   affected DSU configurations. This errata applies only for those DSUs that
+   revision is r0p0 (on r0p1 it is fixed). However, please note that this
+   workaround results in increased DSU power consumption on idle.
+
+-  ``ERRATA_DSU_936184``: This applies errata 936184 workaround for the
+   affected DSU configurations. This errata applies only for those DSUs that
+   contain the ACP interface **and** the DSU revision is older than r2p0 (on
+   r2p0 it is fixed). However, please note that this workaround results in
+   increased DSU power consumption on idle.
+
+-  ``ERRATA_DSU_2313941``: This applies errata 2313941 workaround for the
+   affected DSU configurations. This errata applies for those DSUs with
+   revisions r0p0, r1p0, r2p0, r2p1, r3p0, r3p1 and is still open. However,
+   please note that this workaround results in increased DSU power consumption
+   on idle.
+
+CPU Specific optimizations
+--------------------------
+
+This section describes some of the optimizations allowed by the CPU micro
+architecture that can be enabled by the platform as desired.
+
+-  ``SKIP_A57_L1_FLUSH_PWR_DWN``: This flag enables an optimization in the
+   Cortex-A57 cluster power down sequence by not flushing the Level 1 data
+   cache. The L1 data cache and the L2 unified cache are inclusive. A flush
+   of the L2 by set/way flushes any dirty lines from the L1 as well. This
+   is a known safe deviation from the Cortex-A57 TRM defined power down
+   sequence. Each Cortex-A57 based platform must make its own decision on
+   whether to use the optimization.
+
+-  ``A53_DISABLE_NON_TEMPORAL_HINT``: This flag disables the cache non-temporal
+   hint. The LDNP/STNP instructions as implemented on Cortex-A53 do not behave
+   in a way most programmers expect, and will most probably result in a
+   significant speed degradation to any code that employs them. The Armv8-A
+   architecture (see Arm DDI 0487A.h, section D3.4.3) allows cores to ignore
+   the non-temporal hint and treat LDNP/STNP as LDP/STP instead. Enabling this
+   flag enforces this behaviour. This needs to be enabled only for revisions
+   <= r0p3 of the CPU and is enabled by default.
+
+-  ``A57_DISABLE_NON_TEMPORAL_HINT``: This flag has the same behaviour as
+   ``A53_DISABLE_NON_TEMPORAL_HINT`` but for Cortex-A57. This needs to be
+   enabled only for revisions <= r1p2 of the CPU and is enabled by default,
+   as recommended in section "4.7 Non-Temporal Loads/Stores" of the
+   `Cortex-A57 Software Optimization Guide`_.
+
+- ''A57_ENABLE_NON_CACHEABLE_LOAD_FWD'': This flag enables non-cacheable
+   streaming enhancement feature for Cortex-A57 CPUs. Platforms can set
+   this bit only if their memory system meets the requirement that cache
+   line fill requests from the Cortex-A57 processor are atomic. Each
+   Cortex-A57 based platform must make its own decision on whether to use
+   the optimization. This flag is disabled by default.
+
+-  ``NEOVERSE_Nx_EXTERNAL_LLC``: This flag indicates that an external last
+   level cache(LLC) is present in the system, and that the DataSource field
+   on the master CHI interface indicates when data is returned from the LLC.
+   This is used to control how the LL_CACHE* PMU events count.
+   Default value is 0 (Disabled).
+
+GIC Errata Workarounds
+----------------------
+-  ``GIC600_ERRATA_WA_2384374``: This flag applies part 2 of errata 2384374
+   workaround for the affected GIC600 and GIC600-AE implementations. It applies
+   to implementations of GIC600 and GIC600-AE with revisions less than or equal
+   to r1p6 and r0p2 respectively. If the platform sets GICV3_SUPPORT_GIC600,
+   then this flag is enabled; otherwise, it is 0 (Disabled).

+Firmware Design
+===============
+
+Trusted Firmware-A (TF-A) implements a subset of the Trusted Board Boot
+Requirements (TBBR) Platform Design Document (PDD) for Arm reference
+platforms.
+
+The TBB sequence starts when the platform is powered on and runs up
+to the stage where it hands-off control to firmware running in the normal
+world in DRAM. This is the cold boot path.
+
+TF-A also implements the `Power State Coordination Interface PDD`_ as a
+runtime service. PSCI is the interface from normal world software to firmware
+implementing power management use-cases (for example, secondary CPU boot,
+hotplug and idle). Normal world software can access TF-A runtime services via
+the Arm SMC (Secure Monitor Call) instruction. The SMC instruction must be
+used as mandated by the SMC Calling Convention (`SMCCC`_).
+
+TF-A implements a framework for configuring and managing interrupts generated
+in either security state. The details of the interrupt management framework
+and its design can be found in :ref:`Interrupt Management Framework`.
+
+TF-A also implements a library for setting up and managing the translation
+tables. The details of this library can be found in
+:ref:`Translation (XLAT) Tables Library`.
+
+TF-A can be built to support either AArch64 or AArch32 execution state.
+
+.. note::
+
+ The descriptions in this chapter are for the Arm TrustZone architecture.
+ For changes to the firmware design for the
+ `Arm Confidential Compute Architecture (Arm CCA)`_ please refer to the
+ chapter :ref:`Realm Management Extension (RME)`.
+
+Cold boot
+---------
+
+The cold boot path starts when the platform is physically turned on. If
+``COLD_BOOT_SINGLE_CPU=0``, one of the CPUs released from reset is chosen as the
+primary CPU, and the remaining CPUs are considered secondary CPUs. The primary
+CPU is chosen through platform-specific means. The cold boot path is mainly
+executed by the primary CPU, other than essential CPU initialization executed by
+all CPUs. The secondary CPUs are kept in a safe platform-specific state until
+the primary CPU has performed enough initialization to boot them.
+
+Refer to the :ref:`CPU Reset` for more information on the effect of the
+``COLD_BOOT_SINGLE_CPU`` platform build option.
+
+The cold boot path in this implementation of TF-A depends on the execution
+state. For AArch64, it is divided into five steps (in order of execution):
+
+-  Boot Loader stage 1 (BL1) *AP Trusted ROM*
+-  Boot Loader stage 2 (BL2) *Trusted Boot Firmware*
+-  Boot Loader stage 3-1 (BL31) *EL3 Runtime Software*
+-  Boot Loader stage 3-2 (BL32) *Secure-EL1 Payload* (optional)
+-  Boot Loader stage 3-3 (BL33) *Non-trusted Firmware*
+
+For AArch32, it is divided into four steps (in order of execution):
+
+-  Boot Loader stage 1 (BL1) *AP Trusted ROM*
+-  Boot Loader stage 2 (BL2) *Trusted Boot Firmware*
+-  Boot Loader stage 3-2 (BL32) *EL3 Runtime Software*
+-  Boot Loader stage 3-3 (BL33) *Non-trusted Firmware*
+
+Arm development platforms (Fixed Virtual Platforms (FVPs) and Juno) implement a
+combination of the following types of memory regions. Each bootloader stage uses
+one or more of these memory regions.
+
+-  Regions accessible from both non-secure and secure states. For example,
+   non-trusted SRAM, ROM and DRAM.
+-  Regions accessible from only the secure state. For example, trusted SRAM and
+   ROM. The FVPs also implement the trusted DRAM which is statically
+   configured. Additionally, the Base FVPs and Juno development platform
+   configure the TrustZone Controller (TZC) to create a region in the DRAM
+   which is accessible only from the secure state.
+
+The sections below provide the following details:
+
+-  dynamic configuration of Boot Loader stages
+-  initialization and execution of the first three stages during cold boot
+-  specification of the EL3 Runtime Software (BL31 for AArch64 and BL32 for
+   AArch32) entrypoint requirements for use by alternative Trusted Boot
+   Firmware in place of the provided BL1 and BL2
+
+Dynamic Configuration during cold boot
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Each of the Boot Loader stages may be dynamically configured if required by the
+platform. The Boot Loader stage may optionally specify a firmware
+configuration file and/or hardware configuration file as listed below:
+
+-  FW_CONFIG - The firmware configuration file. Holds properties shared across
+   all BLx images.
+   An example is the "dtb-registry" node, which contains the information about
+   the other device tree configurations (load-address, size, image_id).
+-  HW_CONFIG - The hardware configuration file. Can be shared by all Boot Loader
+   stages and also by the Normal World Rich OS.
+-  TB_FW_CONFIG - Trusted Boot Firmware configuration file. Shared between BL1
+   and BL2.
+-  SOC_FW_CONFIG - SoC Firmware configuration file. Used by BL31.
+-  TOS_FW_CONFIG - Trusted OS Firmware configuration file. Used by Trusted OS
+   (BL32).
+-  NT_FW_CONFIG - Non Trusted Firmware configuration file. Used by Non-trusted
+   firmware (BL33).
+
+The Arm development platforms use the Flattened Device Tree format for the
+dynamic configuration files.
+
+Each Boot Loader stage can pass up to 4 arguments via registers to the next
+stage.  BL2 passes the list of the next images to execute to the *EL3 Runtime
+Software* (BL31 for AArch64 and BL32 for AArch32) via `arg0`. All the other
+arguments are platform defined. The Arm development platforms use the following
+convention:
+
+-  BL1 passes the address of a meminfo_t structure to BL2 via ``arg1``. This
+   structure contains the memory layout available to BL2.
+-  When dynamic configuration files are present, the firmware configuration for
+   the next Boot Loader stage is populated in the first available argument and
+   the generic hardware configuration is passed the next available argument.
+   For example,
+
+   -  FW_CONFIG is loaded by BL1, then its address is passed in ``arg0`` to BL2.
+   -  TB_FW_CONFIG address is retrieved by BL2 from FW_CONFIG device tree.
+   -  If HW_CONFIG is loaded by BL1, then its address is passed in ``arg2`` to
+      BL2. Note, ``arg1`` is already used for meminfo_t.
+   -  If SOC_FW_CONFIG is loaded by BL2, then its address is passed in ``arg1``
+      to BL31. Note, ``arg0`` is used to pass the list of executable images.
+   -  Similarly, if HW_CONFIG is loaded by BL1 or BL2, then its address is
+      passed in ``arg2`` to BL31.
+   -  For other BL3x images, if the firmware configuration file is loaded by
+      BL2, then its address is passed in ``arg0`` and if HW_CONFIG is loaded
+      then its address is passed in ``arg1``.
+   -  In case of the Arm FVP platform, FW_CONFIG address passed in ``arg1`` to
+      BL31/SP_MIN, and the SOC_FW_CONFIG and HW_CONFIG details are retrieved
+      from FW_CONFIG device tree.
+
+BL1
+~~~
+
+This stage begins execution from the platform's reset vector at EL3. The reset
+address is platform dependent but it is usually located in a Trusted ROM area.
+The BL1 data section is copied to trusted SRAM at runtime.
+
+On the Arm development platforms, BL1 code starts execution from the reset
+vector defined by the constant ``BL1_RO_BASE``. The BL1 data section is copied
+to the top of trusted SRAM as defined by the constant ``BL1_RW_BASE``.
+
+The functionality implemented by this stage is as follows.
+
+Determination of boot path
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Whenever a CPU is released from reset, BL1 needs to distinguish between a warm
+boot and a cold boot. This is done using platform-specific mechanisms (see the
+``plat_get_my_entrypoint()`` function in the :ref:`Porting Guide`). In the case
+of a warm boot, a CPU is expected to continue execution from a separate
+entrypoint. In the case of a cold boot, the secondary CPUs are placed in a safe
+platform-specific state (see the ``plat_secondary_cold_boot_setup()`` function in
+the :ref:`Porting Guide`) while the primary CPU executes the remaining cold boot
+path as described in the following sections.
+
+This step only applies when ``PROGRAMMABLE_RESET_ADDRESS=0``. Refer to the
+:ref:`CPU Reset` for more information on the effect of the
+``PROGRAMMABLE_RESET_ADDRESS`` platform build option.
+
+Architectural initialization
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+BL1 performs minimal architectural initialization as follows.
+
+-  Exception vectors
+
+   BL1 sets up simple exception vectors for both synchronous and asynchronous
+   exceptions. The default behavior upon receiving an exception is to populate
+   a status code in the general purpose register ``X0/R0`` and call the
+   ``plat_report_exception()`` function (see the :ref:`Porting Guide`). The
+   status code is one of:
+
+   For AArch64:
+
+   ::
+
+       0x0 : Synchronous exception from Current EL with SP_EL0
+       0x1 : IRQ exception from Current EL with SP_EL0
+       0x2 : FIQ exception from Current EL with SP_EL0
+       0x3 : System Error exception from Current EL with SP_EL0
+       0x4 : Synchronous exception from Current EL with SP_ELx
+       0x5 : IRQ exception from Current EL with SP_ELx
+       0x6 : FIQ exception from Current EL with SP_ELx
+       0x7 : System Error exception from Current EL with SP_ELx
+       0x8 : Synchronous exception from Lower EL using aarch64
+       0x9 : IRQ exception from Lower EL using aarch64
+       0xa : FIQ exception from Lower EL using aarch64
+       0xb : System Error exception from Lower EL using aarch64
+       0xc : Synchronous exception from Lower EL using aarch32
+       0xd : IRQ exception from Lower EL using aarch32
+       0xe : FIQ exception from Lower EL using aarch32
+       0xf : System Error exception from Lower EL using aarch32
+
+   For AArch32:
+
+   ::
+
+       0x10 : User mode
+       0x11 : FIQ mode
+       0x12 : IRQ mode
+       0x13 : SVC mode
+       0x16 : Monitor mode
+       0x17 : Abort mode
+       0x1a : Hypervisor mode
+       0x1b : Undefined mode
+       0x1f : System mode
+
+   The ``plat_report_exception()`` implementation on the Arm FVP port programs
+   the Versatile Express System LED register in the following format to
+   indicate the occurrence of an unexpected exception:
+
+   ::
+
+       SYS_LED[0]   - Security state (Secure=0/Non-Secure=1)
+       SYS_LED[2:1] - Exception Level (EL3=0x3, EL2=0x2, EL1=0x1, EL0=0x0)
+                      For AArch32 it is always 0x0
+       SYS_LED[7:3] - Exception Class (Sync/Async & origin). This is the value
+                      of the status code
+
+   A write to the LED register reflects in the System LEDs (S6LED0..7) in the
+   CLCD window of the FVP.
+
+   BL1 does not expect to receive any exceptions other than the SMC exception.
+   For the latter, BL1 installs a simple stub. The stub expects to receive a
+   limited set of SMC types (determined by their function IDs in the general
+   purpose register ``X0/R0``):
+
+   -  ``BL1_SMC_RUN_IMAGE``: This SMC is raised by BL2 to make BL1 pass control
+      to EL3 Runtime Software.
+   -  All SMCs listed in section "BL1 SMC Interface" in the :ref:`Firmware Update (FWU)`
+      Design Guide are supported for AArch64 only. These SMCs are currently
+      not supported when BL1 is built for AArch32.
+
+   Any other SMC leads to an assertion failure.
+
+-  CPU initialization
+
+   BL1 calls the ``reset_handler()`` function which in turn calls the CPU
+   specific reset handler function (see the section: "CPU specific operations
+   framework").
+
+-  Control register setup (for AArch64)
+
+   -  ``SCTLR_EL3``. Instruction cache is enabled by setting the ``SCTLR_EL3.I``
+      bit. Alignment and stack alignment checking is enabled by setting the
+      ``SCTLR_EL3.A`` and ``SCTLR_EL3.SA`` bits. Exception endianness is set to
+      little-endian by clearing the ``SCTLR_EL3.EE`` bit.
+
+   -  ``SCR_EL3``. The register width of the next lower exception level is set
+      to AArch64 by setting the ``SCR.RW`` bit. The ``SCR.EA`` bit is set to trap
+      both External Aborts and SError Interrupts in EL3. The ``SCR.SIF`` bit is
+      also set to disable instruction fetches from Non-secure memory when in
+      secure state.
+
+   -  ``CPTR_EL3``. Accesses to the ``CPACR_EL1`` register from EL1 or EL2, or the
+      ``CPTR_EL2`` register from EL2 are configured to not trap to EL3 by
+      clearing the ``CPTR_EL3.TCPAC`` bit. Access to the trace functionality is
+      configured not to trap to EL3 by clearing the ``CPTR_EL3.TTA`` bit.
+      Instructions that access the registers associated with Floating Point
+      and Advanced SIMD execution are configured to not trap to EL3 by
+      clearing the ``CPTR_EL3.TFP`` bit.
+
+   -  ``DAIF``. The SError interrupt is enabled by clearing the SError interrupt
+      mask bit.
+
+   -  ``MDCR_EL3``. The trap controls, ``MDCR_EL3.TDOSA``, ``MDCR_EL3.TDA`` and
+      ``MDCR_EL3.TPM``, are set so that accesses to the registers they control
+      do not trap to EL3. AArch64 Secure self-hosted debug is disabled by
+      setting the ``MDCR_EL3.SDD`` bit. Also ``MDCR_EL3.SPD32`` is set to
+      disable AArch32 Secure self-hosted privileged debug from S-EL1.
+
+-  Control register setup (for AArch32)
+
+   -  ``SCTLR``. Instruction cache is enabled by setting the ``SCTLR.I`` bit.
+      Alignment checking is enabled by setting the ``SCTLR.A`` bit.
+      Exception endianness is set to little-endian by clearing the
+      ``SCTLR.EE`` bit.
+
+   -  ``SCR``. The ``SCR.SIF`` bit is set to disable instruction fetches from
+      Non-secure memory when in secure state.
+
+   -  ``CPACR``. Allow execution of Advanced SIMD instructions at PL0 and PL1,
+      by clearing the ``CPACR.ASEDIS`` bit. Access to the trace functionality
+      is configured not to trap to undefined mode by clearing the
+      ``CPACR.TRCDIS`` bit.
+
+   -  ``NSACR``. Enable non-secure access to Advanced SIMD functionality and
+      system register access to implemented trace registers.
+
+   -  ``FPEXC``. Enable access to the Advanced SIMD and floating-point
+      functionality from all Exception levels.
+
+   -  ``CPSR.A``. The Asynchronous data abort interrupt is enabled by clearing
+      the Asynchronous data abort interrupt mask bit.
+
+   -  ``SDCR``. The ``SDCR.SPD`` field is set to disable AArch32 Secure
+      self-hosted privileged debug.
+
+Platform initialization
+^^^^^^^^^^^^^^^^^^^^^^^
+
+On Arm platforms, BL1 performs the following platform initializations:
+
+-  Enable the Trusted Watchdog.
+-  Initialize the console.
+-  Configure the Interconnect to enable hardware coherency.
+-  Enable the MMU and map the memory it needs to access.
+-  Configure any required platform storage to load the next bootloader image
+   (BL2).
+-  If the BL1 dynamic configuration file, ``TB_FW_CONFIG``, is available, then
+   load it to the platform defined address and make it available to BL2 via
+   ``arg0``.
+-  Configure the system timer and program the `CNTFRQ_EL0` for use by NS-BL1U
+   and NS-BL2U firmware update images.
+
+Firmware Update detection and execution
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+After performing platform setup, BL1 common code calls
+``bl1_plat_get_next_image_id()`` to determine if :ref:`Firmware Update (FWU)` is
+required or to proceed with the normal boot process. If the platform code
+returns ``BL2_IMAGE_ID`` then the normal boot sequence is executed as described
+in the next section, else BL1 assumes that :ref:`Firmware Update (FWU)` is
+required and execution passes to the first image in the
+:ref:`Firmware Update (FWU)` process. In either case, BL1 retrieves a descriptor
+of the next image by calling ``bl1_plat_get_image_desc()``. The image descriptor
+contains an ``entry_point_info_t`` structure, which BL1 uses to initialize the
+execution state of the next image.
+
+BL2 image load and execution
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+In the normal boot flow, BL1 execution continues as follows:
+
+#. BL1 prints the following string from the primary CPU to indicate successful
+   execution of the BL1 stage:
+
+   ::
+
+       "Booting Trusted Firmware"
+
+#. BL1 loads a BL2 raw binary image from platform storage, at a
+   platform-specific base address. Prior to the load, BL1 invokes
+   ``bl1_plat_handle_pre_image_load()`` which allows the platform to update or
+   use the image information. If the BL2 image file is not present or if
+   there is not enough free trusted SRAM the following error message is
+   printed:
+
+   ::
+
+       "Failed to load BL2 firmware."
+
+#. BL1 invokes ``bl1_plat_handle_post_image_load()`` which again is intended
+   for platforms to take further action after image load. This function must
+   populate the necessary arguments for BL2, which may also include the memory
+   layout. Further description of the memory layout can be found later
+   in this document.
+
+#. BL1 passes control to the BL2 image at Secure EL1 (for AArch64) or at
+   Secure SVC mode (for AArch32), starting from its load address.
+
+BL2
+~~~
+
+BL1 loads and passes control to BL2 at Secure-EL1 (for AArch64) or at Secure
+SVC mode (for AArch32) . BL2 is linked against and loaded at a platform-specific
+base address (more information can be found later in this document).
+The functionality implemented by BL2 is as follows.
+
+Architectural initialization
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+For AArch64, BL2 performs the minimal architectural initialization required
+for subsequent stages of TF-A and normal world software. EL1 and EL0 are given
+access to Floating Point and Advanced SIMD registers by setting the
+``CPACR.FPEN`` bits.
+
+For AArch32, the minimal architectural initialization required for subsequent
+stages of TF-A and normal world software is taken care of in BL1 as both BL1
+and BL2 execute at PL1.
+
+Platform initialization
+^^^^^^^^^^^^^^^^^^^^^^^
+
+On Arm platforms, BL2 performs the following platform initializations:
+
+-  Initialize the console.
+-  Configure any required platform storage to allow loading further bootloader
+   images.
+-  Enable the MMU and map the memory it needs to access.
+-  Perform platform security setup to allow access to controlled components.
+-  Reserve some memory for passing information to the next bootloader image
+   EL3 Runtime Software and populate it.
+-  Define the extents of memory available for loading each subsequent
+   bootloader image.
+-  If BL1 has passed TB_FW_CONFIG dynamic configuration file in ``arg0``,
+   then parse it.
+
+Image loading in BL2
+^^^^^^^^^^^^^^^^^^^^
+
+BL2 generic code loads the images based on the list of loadable images
+provided by the platform. BL2 passes the list of executable images
+provided by the platform to the next handover BL image.
+
+The list of loadable images provided by the platform may also contain
+dynamic configuration files. The files are loaded and can be parsed as
+needed in the ``bl2_plat_handle_post_image_load()`` function. These
+configuration files can be passed to next Boot Loader stages as arguments
+by updating the corresponding entrypoint information in this function.
+
+SCP_BL2 (System Control Processor Firmware) image load
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Some systems have a separate System Control Processor (SCP) for power, clock,
+reset and system control. BL2 loads the optional SCP_BL2 image from platform
+storage into a platform-specific region of secure memory. The subsequent
+handling of SCP_BL2 is platform specific. For example, on the Juno Arm
+development platform port the image is transferred into SCP's internal memory
+using the Boot Over MHU (BOM) protocol after being loaded in the trusted SRAM
+memory. The SCP executes SCP_BL2 and signals to the Application Processor (AP)
+for BL2 execution to continue.
+
+EL3 Runtime Software image load
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+BL2 loads the EL3 Runtime Software image from platform storage into a platform-
+specific address in trusted SRAM. If there is not enough memory to load the
+image or image is missing it leads to an assertion failure.
+
+AArch64 BL32 (Secure-EL1 Payload) image load
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+BL2 loads the optional BL32 image from platform storage into a platform-
+specific region of secure memory. The image executes in the secure world. BL2
+relies on BL31 to pass control to the BL32 image, if present. Hence, BL2
+populates a platform-specific area of memory with the entrypoint/load-address
+of the BL32 image. The value of the Saved Processor Status Register (``SPSR``)
+for entry into BL32 is not determined by BL2, it is initialized by the
+Secure-EL1 Payload Dispatcher (see later) within BL31, which is responsible for
+managing interaction with BL32. This information is passed to BL31.
+
+BL33 (Non-trusted Firmware) image load
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+BL2 loads the BL33 image (e.g. UEFI or other test or boot software) from
+platform storage into non-secure memory as defined by the platform.
+
+BL2 relies on EL3 Runtime Software to pass control to BL33 once secure state
+initialization is complete. Hence, BL2 populates a platform-specific area of
+memory with the entrypoint and Saved Program Status Register (``SPSR``) of the
+normal world software image. The entrypoint is the load address of the BL33
+image. The ``SPSR`` is determined as specified in Section 5.13 of the
+`Power State Coordination Interface PDD`_. This information is passed to the
+EL3 Runtime Software.
+
+AArch64 BL31 (EL3 Runtime Software) execution
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+BL2 execution continues as follows:
+
+#. BL2 passes control back to BL1 by raising an SMC, providing BL1 with the
+   BL31 entrypoint. The exception is handled by the SMC exception handler
+   installed by BL1.
+
+#. BL1 turns off the MMU and flushes the caches. It clears the
+   ``SCTLR_EL3.M/I/C`` bits, flushes the data cache to the point of coherency
+   and invalidates the TLBs.
+
+#. BL1 passes control to BL31 at the specified entrypoint at EL3.
+
+Running BL2 at EL3 execution level
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Some platforms have a non-TF-A Boot ROM that expects the next boot stage
+to execute at EL3. On these platforms, TF-A BL1 is a waste of memory
+as its only purpose is to ensure TF-A BL2 is entered at S-EL1. To avoid
+this waste, a special mode enables BL2 to execute at EL3, which allows
+a non-TF-A Boot ROM to load and jump directly to BL2. This mode is selected
+when the build flag BL2_AT_EL3 is enabled. The main differences in this
+mode are:
+
+#. BL2 includes the reset code and the mailbox mechanism to differentiate
+   cold boot and warm boot. It runs at EL3 doing the arch
+   initialization required for EL3.
+
+#. BL2 does not receive the meminfo information from BL1 anymore. This
+   information can be passed by the Boot ROM or be internal to the
+   BL2 image.
+
+#. Since BL2 executes at EL3, BL2 jumps directly to the next image,
+   instead of invoking the RUN_IMAGE SMC call.
+
+
+We assume 3 different types of BootROM support on the platform:
+
+#. The Boot ROM always jumps to the same address, for both cold
+   and warm boot. In this case, we will need to keep a resident part
+   of BL2 whose memory cannot be reclaimed by any other image. The
+   linker script defines the symbols __TEXT_RESIDENT_START__ and
+   __TEXT_RESIDENT_END__ that allows the platform to configure
+   correctly the memory map.
+#. The platform has some mechanism to indicate the jump address to the
+   Boot ROM. Platform code can then program the jump address with
+   psci_warmboot_entrypoint during cold boot.
+#. The platform has some mechanism to program the reset address using
+   the PROGRAMMABLE_RESET_ADDRESS feature. Platform code can then
+   program the reset address with psci_warmboot_entrypoint during
+   cold boot, bypassing the boot ROM for warm boot.
+
+In the last 2 cases, no part of BL2 needs to remain resident at
+runtime. In the first 2 cases, we expect the Boot ROM to be able to
+differentiate between warm and cold boot, to avoid loading BL2 again
+during warm boot.
+
+This functionality can be tested with FVP loading the image directly
+in memory and changing the address where the system jumps at reset.
+For example:
+
+	-C cluster0.cpu0.RVBAR=0x4022000
+	--data cluster0.cpu0=bl2.bin@0x4022000
+
+With this configuration, FVP is like a platform of the first case,
+where the Boot ROM jumps always to the same address. For simplification,
+BL32 is loaded in DRAM in this case, to avoid other images reclaiming
+BL2 memory.
+
+
+AArch64 BL31
+~~~~~~~~~~~~
+
+The image for this stage is loaded by BL2 and BL1 passes control to BL31 at
+EL3. BL31 executes solely in trusted SRAM. BL31 is linked against and
+loaded at a platform-specific base address (more information can be found later
+in this document). The functionality implemented by BL31 is as follows.
+
+Architectural initialization
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Currently, BL31 performs a similar architectural initialization to BL1 as
+far as system register settings are concerned. Since BL1 code resides in ROM,
+architectural initialization in BL31 allows override of any previous
+initialization done by BL1.
+
+BL31 initializes the per-CPU data framework, which provides a cache of
+frequently accessed per-CPU data optimised for fast, concurrent manipulation
+on different CPUs. This buffer includes pointers to per-CPU contexts, crash
+buffer, CPU reset and power down operations, PSCI data, platform data and so on.
+
+It then replaces the exception vectors populated by BL1 with its own. BL31
+exception vectors implement more elaborate support for handling SMCs since this
+is the only mechanism to access the runtime services implemented by BL31 (PSCI
+for example). BL31 checks each SMC for validity as specified by the
+`SMC Calling Convention`_ before passing control to the required SMC
+handler routine.
+
+BL31 programs the ``CNTFRQ_EL0`` register with the clock frequency of the system
+counter, which is provided by the platform.
+
+Platform initialization
+^^^^^^^^^^^^^^^^^^^^^^^
+
+BL31 performs detailed platform initialization, which enables normal world
+software to function correctly.
+
+On Arm platforms, this consists of the following:
+
+-  Initialize the console.
+-  Configure the Interconnect to enable hardware coherency.
+-  Enable the MMU and map the memory it needs to access.
+-  Initialize the generic interrupt controller.
+-  Initialize the power controller device.
+-  Detect the system topology.
+
+Runtime services initialization
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+BL31 is responsible for initializing the runtime services. One of them is PSCI.
+
+As part of the PSCI initializations, BL31 detects the system topology. It also
+initializes the data structures that implement the state machine used to track
+the state of power domain nodes. The state can be one of ``OFF``, ``RUN`` or
+``RETENTION``. All secondary CPUs are initially in the ``OFF`` state. The cluster
+that the primary CPU belongs to is ``ON``; any other cluster is ``OFF``. It also
+initializes the locks that protect them. BL31 accesses the state of a CPU or
+cluster immediately after reset and before the data cache is enabled in the
+warm boot path. It is not currently possible to use 'exclusive' based spinlocks,
+therefore BL31 uses locks based on Lamport's Bakery algorithm instead.
+
+The runtime service framework and its initialization is described in more
+detail in the "EL3 runtime services framework" section below.
+
+Details about the status of the PSCI implementation are provided in the
+"Power State Coordination Interface" section below.
+
+AArch64 BL32 (Secure-EL1 Payload) image initialization
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+If a BL32 image is present then there must be a matching Secure-EL1 Payload
+Dispatcher (SPD) service (see later for details). During initialization
+that service must register a function to carry out initialization of BL32
+once the runtime services are fully initialized. BL31 invokes such a
+registered function to initialize BL32 before running BL33. This initialization
+is not necessary for AArch32 SPs.
+
+Details on BL32 initialization and the SPD's role are described in the
+:ref:`firmware_design_sel1_spd` section below.
+
+BL33 (Non-trusted Firmware) execution
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+EL3 Runtime Software initializes the EL2 or EL1 processor context for normal-
+world cold boot, ensuring that no secure state information finds its way into
+the non-secure execution state. EL3 Runtime Software uses the entrypoint
+information provided by BL2 to jump to the Non-trusted firmware image (BL33)
+at the highest available Exception Level (EL2 if available, otherwise EL1).
+
+Using alternative Trusted Boot Firmware in place of BL1 & BL2 (AArch64 only)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Some platforms have existing implementations of Trusted Boot Firmware that
+would like to use TF-A BL31 for the EL3 Runtime Software. To enable this
+firmware architecture it is important to provide a fully documented and stable
+interface between the Trusted Boot Firmware and BL31.
+
+Future changes to the BL31 interface will be done in a backwards compatible
+way, and this enables these firmware components to be independently enhanced/
+updated to develop and exploit new functionality.
+
+Required CPU state when calling ``bl31_entrypoint()`` during cold boot
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+This function must only be called by the primary CPU.
+
+On entry to this function the calling primary CPU must be executing in AArch64
+EL3, little-endian data access, and all interrupt sources masked:
+
+::
+
+    PSTATE.EL = 3
+    PSTATE.RW = 1
+    PSTATE.DAIF = 0xf
+    SCTLR_EL3.EE = 0
+
+X0 and X1 can be used to pass information from the Trusted Boot Firmware to the
+platform code in BL31:
+
+::
+
+    X0 : Reserved for common TF-A information
+    X1 : Platform specific information
+
+BL31 zero-init sections (e.g. ``.bss``) should not contain valid data on entry,
+these will be zero filled prior to invoking platform setup code.
+
+Use of the X0 and X1 parameters
+'''''''''''''''''''''''''''''''
+
+The parameters are platform specific and passed from ``bl31_entrypoint()`` to
+``bl31_early_platform_setup()``. The value of these parameters is never directly
+used by the common BL31 code.
+
+The convention is that ``X0`` conveys information regarding the BL31, BL32 and
+BL33 images from the Trusted Boot firmware and ``X1`` can be used for other
+platform specific purpose. This convention allows platforms which use TF-A's
+BL1 and BL2 images to transfer additional platform specific information from
+Secure Boot without conflicting with future evolution of TF-A using ``X0`` to
+pass a ``bl31_params`` structure.
+
+BL31 common and SPD initialization code depends on image and entrypoint
+information about BL33 and BL32, which is provided via BL31 platform APIs.
+This information is required until the start of execution of BL33. This
+information can be provided in a platform defined manner, e.g. compiled into
+the platform code in BL31, or provided in a platform defined memory location
+by the Trusted Boot firmware, or passed from the Trusted Boot Firmware via the
+Cold boot Initialization parameters. This data may need to be cleaned out of
+the CPU caches if it is provided by an earlier boot stage and then accessed by
+BL31 platform code before the caches are enabled.
+
+TF-A's BL2 implementation passes a ``bl31_params`` structure in
+``X0`` and the Arm development platforms interpret this in the BL31 platform
+code.
+
+MMU, Data caches & Coherency
+''''''''''''''''''''''''''''
+
+BL31 does not depend on the enabled state of the MMU, data caches or
+interconnect coherency on entry to ``bl31_entrypoint()``. If these are disabled
+on entry, these should be enabled during ``bl31_plat_arch_setup()``.
+
+Data structures used in the BL31 cold boot interface
+''''''''''''''''''''''''''''''''''''''''''''''''''''
+
+These structures are designed to support compatibility and independent
+evolution of the structures and the firmware images. For example, a version of
+BL31 that can interpret the BL3x image information from different versions of
+BL2, a platform that uses an extended entry_point_info structure to convey
+additional register information to BL31, or a ELF image loader that can convey
+more details about the firmware images.
+
+To support these scenarios the structures are versioned and sized, which enables
+BL31 to detect which information is present and respond appropriately. The
+``param_header`` is defined to capture this information:
+
+.. code:: c
+
+    typedef struct param_header {
+        uint8_t type;       /* type of the structure */
+        uint8_t version;    /* version of this structure */
+        uint16_t size;      /* size of this structure in bytes */
+        uint32_t attr;      /* attributes: unused bits SBZ */
+    } param_header_t;
+
+The structures using this format are ``entry_point_info``, ``image_info`` and
+``bl31_params``. The code that allocates and populates these structures must set
+the header fields appropriately, and the ``SET_PARAM_HEAD()`` a macro is defined
+to simplify this action.
+
+Required CPU state for BL31 Warm boot initialization
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+When requesting a CPU power-on, or suspending a running CPU, TF-A provides
+the platform power management code with a Warm boot initialization
+entry-point, to be invoked by the CPU immediately after the reset handler.
+On entry to the Warm boot initialization function the calling CPU must be in
+AArch64 EL3, little-endian data access and all interrupt sources masked:
+
+::
+
+    PSTATE.EL = 3
+    PSTATE.RW = 1
+    PSTATE.DAIF = 0xf
+    SCTLR_EL3.EE = 0
+
+The PSCI implementation will initialize the processor state and ensure that the
+platform power management code is then invoked as required to initialize all
+necessary system, cluster and CPU resources.
+
+AArch32 EL3 Runtime Software entrypoint interface
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+To enable this firmware architecture it is important to provide a fully
+documented and stable interface between the Trusted Boot Firmware and the
+AArch32 EL3 Runtime Software.
+
+Future changes to the entrypoint interface will be done in a backwards
+compatible way, and this enables these firmware components to be independently
+enhanced/updated to develop and exploit new functionality.
+
+Required CPU state when entering during cold boot
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+This function must only be called by the primary CPU.
+
+On entry to this function the calling primary CPU must be executing in AArch32
+EL3, little-endian data access, and all interrupt sources masked:
+
+::
+
+    PSTATE.AIF = 0x7
+    SCTLR.EE = 0
+
+R0 and R1 are used to pass information from the Trusted Boot Firmware to the
+platform code in AArch32 EL3 Runtime Software:
+
+::
+
+    R0 : Reserved for common TF-A information
+    R1 : Platform specific information
+
+Use of the R0 and R1 parameters
+'''''''''''''''''''''''''''''''
+
+The parameters are platform specific and the convention is that ``R0`` conveys
+information regarding the BL3x images from the Trusted Boot firmware and ``R1``
+can be used for other platform specific purpose. This convention allows
+platforms which use TF-A's BL1 and BL2 images to transfer additional platform
+specific information from Secure Boot without conflicting with future
+evolution of TF-A using ``R0`` to pass a ``bl_params`` structure.
+
+The AArch32 EL3 Runtime Software is responsible for entry into BL33. This
+information can be obtained in a platform defined manner, e.g. compiled into
+the AArch32 EL3 Runtime Software, or provided in a platform defined memory
+location by the Trusted Boot firmware, or passed from the Trusted Boot Firmware
+via the Cold boot Initialization parameters. This data may need to be cleaned
+out of the CPU caches if it is provided by an earlier boot stage and then
+accessed by AArch32 EL3 Runtime Software before the caches are enabled.
+
+When using AArch32 EL3 Runtime Software, the Arm development platforms pass a
+``bl_params`` structure in ``R0`` from BL2 to be interpreted by AArch32 EL3 Runtime
+Software platform code.
+
+MMU, Data caches & Coherency
+''''''''''''''''''''''''''''
+
+AArch32 EL3 Runtime Software must not depend on the enabled state of the MMU,
+data caches or interconnect coherency in its entrypoint. They must be explicitly
+enabled if required.
+
+Data structures used in cold boot interface
+'''''''''''''''''''''''''''''''''''''''''''
+
+The AArch32 EL3 Runtime Software cold boot interface uses ``bl_params`` instead
+of ``bl31_params``. The ``bl_params`` structure is based on the convention
+described in AArch64 BL31 cold boot interface section.
+
+Required CPU state for warm boot initialization
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+When requesting a CPU power-on, or suspending a running CPU, AArch32 EL3
+Runtime Software must ensure execution of a warm boot initialization entrypoint.
+If TF-A BL1 is used and the PROGRAMMABLE_RESET_ADDRESS build flag is false,
+then AArch32 EL3 Runtime Software must ensure that BL1 branches to the warm
+boot entrypoint by arranging for the BL1 platform function,
+plat_get_my_entrypoint(), to return a non-zero value.
+
+In this case, the warm boot entrypoint must be in AArch32 EL3, little-endian
+data access and all interrupt sources masked:
+
+::
+
+    PSTATE.AIF = 0x7
+    SCTLR.EE = 0
+
+The warm boot entrypoint may be implemented by using TF-A
+``psci_warmboot_entrypoint()`` function. In that case, the platform must fulfil
+the pre-requisites mentioned in the
+:ref:`PSCI Library Integration guide for Armv8-A AArch32 systems`.
+
+EL3 runtime services framework
+------------------------------
+
+Software executing in the non-secure state and in the secure state at exception
+levels lower than EL3 will request runtime services using the Secure Monitor
+Call (SMC) instruction. These requests will follow the convention described in
+the SMC Calling Convention PDD (`SMCCC`_). The `SMCCC`_ assigns function
+identifiers to each SMC request and describes how arguments are passed and
+returned.
+
+The EL3 runtime services framework enables the development of services by
+different providers that can be easily integrated into final product firmware.
+The following sections describe the framework which facilitates the
+registration, initialization and use of runtime services in EL3 Runtime
+Software (BL31).
+
+The design of the runtime services depends heavily on the concepts and
+definitions described in the `SMCCC`_, in particular SMC Function IDs, Owning
+Entity Numbers (OEN), Fast and Yielding calls, and the SMC32 and SMC64 calling
+conventions. Please refer to that document for more detailed explanation of
+these terms.
+
+The following runtime services are expected to be implemented first. They have
+not all been instantiated in the current implementation.
+
+#. Standard service calls
+
+   This service is for management of the entire system. The Power State
+   Coordination Interface (`PSCI`_) is the first set of standard service calls
+   defined by Arm (see PSCI section later).
+
+#. Secure-EL1 Payload Dispatcher service
+
+   If a system runs a Trusted OS or other Secure-EL1 Payload (SP) then
+   it also requires a *Secure Monitor* at EL3 to switch the EL1 processor
+   context between the normal world (EL1/EL2) and trusted world (Secure-EL1).
+   The Secure Monitor will make these world switches in response to SMCs. The
+   `SMCCC`_ provides for such SMCs with the Trusted OS Call and Trusted
+   Application Call OEN ranges.
+
+   The interface between the EL3 Runtime Software and the Secure-EL1 Payload is
+   not defined by the `SMCCC`_ or any other standard. As a result, each
+   Secure-EL1 Payload requires a specific Secure Monitor that runs as a runtime
+   service - within TF-A this service is referred to as the Secure-EL1 Payload
+   Dispatcher (SPD).
+
+   TF-A provides a Test Secure-EL1 Payload (TSP) and its associated Dispatcher
+   (TSPD). Details of SPD design and TSP/TSPD operation are described in the
+   :ref:`firmware_design_sel1_spd` section below.
+
+#. CPU implementation service
+
+   This service will provide an interface to CPU implementation specific
+   services for a given platform e.g. access to processor errata workarounds.
+   This service is currently unimplemented.
+
+Additional services for Arm Architecture, SiP and OEM calls can be implemented.
+Each implemented service handles a range of SMC function identifiers as
+described in the `SMCCC`_.
+
+Registration
+~~~~~~~~~~~~
+
+A runtime service is registered using the ``DECLARE_RT_SVC()`` macro, specifying
+the name of the service, the range of OENs covered, the type of service and
+initialization and call handler functions. This macro instantiates a ``const struct rt_svc_desc`` for the service with these details (see ``runtime_svc.h``).
+This structure is allocated in a special ELF section ``rt_svc_descs``, enabling
+the framework to find all service descriptors included into BL31.
+
+The specific service for a SMC Function is selected based on the OEN and call
+type of the Function ID, and the framework uses that information in the service
+descriptor to identify the handler for the SMC Call.
+
+The service descriptors do not include information to identify the precise set
+of SMC function identifiers supported by this service implementation, the
+security state from which such calls are valid nor the capability to support
+64-bit and/or 32-bit callers (using SMC32 or SMC64). Responding appropriately
+to these aspects of a SMC call is the responsibility of the service
+implementation, the framework is focused on integration of services from
+different providers and minimizing the time taken by the framework before the
+service handler is invoked.
+
+Details of the parameters, requirements and behavior of the initialization and
+call handling functions are provided in the following sections.
+
+Initialization
+~~~~~~~~~~~~~~
+
+``runtime_svc_init()`` in ``runtime_svc.c`` initializes the runtime services
+framework running on the primary CPU during cold boot as part of the BL31
+initialization. This happens prior to initializing a Trusted OS and running
+Normal world boot firmware that might in turn use these services.
+Initialization involves validating each of the declared runtime service
+descriptors, calling the service initialization function and populating the
+index used for runtime lookup of the service.
+
+The BL31 linker script collects all of the declared service descriptors into a
+single array and defines symbols that allow the framework to locate and traverse
+the array, and determine its size.
+
+The framework does basic validation of each descriptor to halt firmware
+initialization if service declaration errors are detected. The framework does
+not check descriptors for the following error conditions, and may behave in an
+unpredictable manner under such scenarios:
+
+#. Overlapping OEN ranges
+#. Multiple descriptors for the same range of OENs and ``call_type``
+#. Incorrect range of owning entity numbers for a given ``call_type``
+
+Once validated, the service ``init()`` callback is invoked. This function carries
+out any essential EL3 initialization before servicing requests. The ``init()``
+function is only invoked on the primary CPU during cold boot. If the service
+uses per-CPU data this must either be initialized for all CPUs during this call,
+or be done lazily when a CPU first issues an SMC call to that service. If
+``init()`` returns anything other than ``0``, this is treated as an initialization
+error and the service is ignored: this does not cause the firmware to halt.
+
+The OEN and call type fields present in the SMC Function ID cover a total of
+128 distinct services, but in practice a single descriptor can cover a range of
+OENs, e.g. SMCs to call a Trusted OS function. To optimize the lookup of a
+service handler, the framework uses an array of 128 indices that map every
+distinct OEN/call-type combination either to one of the declared services or to
+indicate the service is not handled. This ``rt_svc_descs_indices[]`` array is
+populated for all of the OENs covered by a service after the service ``init()``
+function has reported success. So a service that fails to initialize will never
+have it's ``handle()`` function invoked.
+
+The following figure shows how the ``rt_svc_descs_indices[]`` index maps the SMC
+Function ID call type and OEN onto a specific service handler in the
+``rt_svc_descs[]`` array.
+
+|Image 1|
+
+.. _handling-an-smc:
+
+Handling an SMC
+~~~~~~~~~~~~~~~
+
+When the EL3 runtime services framework receives a Secure Monitor Call, the SMC
+Function ID is passed in W0 from the lower exception level (as per the
+`SMCCC`_). If the calling register width is AArch32, it is invalid to invoke an
+SMC Function which indicates the SMC64 calling convention: such calls are
+ignored and return the Unknown SMC Function Identifier result code ``0xFFFFFFFF``
+in R0/X0.
+
+Bit[31] (fast/yielding call) and bits[29:24] (owning entity number) of the SMC
+Function ID are combined to index into the ``rt_svc_descs_indices[]`` array. The
+resulting value might indicate a service that has no handler, in this case the
+framework will also report an Unknown SMC Function ID. Otherwise, the value is
+used as a further index into the ``rt_svc_descs[]`` array to locate the required
+service and handler.
+
+The service's ``handle()`` callback is provided with five of the SMC parameters
+directly, the others are saved into memory for retrieval (if needed) by the
+handler. The handler is also provided with an opaque ``handle`` for use with the
+supporting library for parameter retrieval, setting return values and context
+manipulation. The ``flags`` parameter indicates the security state of the caller
+and the state of the SVE hint bit per the SMCCCv1.3. The framework finally sets
+up the execution stack for the handler, and invokes the services ``handle()``
+function.
+
+On return from the handler the result registers are populated in X0-X7 as needed
+before restoring the stack and CPU state and returning from the original SMC.
+
+Exception Handling Framework
+----------------------------
+
+Please refer to the :ref:`Exception Handling Framework` document.
+
+Power State Coordination Interface
+----------------------------------
+
+TODO: Provide design walkthrough of PSCI implementation.
+
+The PSCI v1.1 specification categorizes APIs as optional and mandatory. All the
+mandatory APIs in PSCI v1.1, PSCI v1.0 and in PSCI v0.2 draft specification
+`Power State Coordination Interface PDD`_ are implemented. The table lists
+the PSCI v1.1 APIs and their support in generic code.
+
+An API implementation might have a dependency on platform code e.g. CPU_SUSPEND
+requires the platform to export a part of the implementation. Hence the level
+of support of the mandatory APIs depends upon the support exported by the
+platform port as well. The Juno and FVP (all variants) platforms export all the
+required support.

+
+Secure-EL1 Payloads and Dispatchers
+-----------------------------------
+
+On a production system that includes a Trusted OS running in Secure-EL1/EL0,
+the Trusted OS is coupled with a companion runtime service in the BL31
+firmware. This service is responsible for the initialisation of the Trusted
+OS and all communications with it. The Trusted OS is the BL32 stage of the
+boot flow in TF-A. The firmware will attempt to locate, load and execute a
+BL32 image.
+
+TF-A uses a more general term for the BL32 software that runs at Secure-EL1 -
+the *Secure-EL1 Payload* - as it is not always a Trusted OS.
+
+TF-A provides a Test Secure-EL1 Payload (TSP) and a Test Secure-EL1 Payload
+Dispatcher (TSPD) service as an example of how a Trusted OS is supported on a
+production system using the Runtime Services Framework. On such a system, the
+Test BL32 image and service are replaced by the Trusted OS and its dispatcher
+service. The TF-A build system expects that the dispatcher will define the
+build flag ``NEED_BL32`` to enable it to include the BL32 in the build either
+as a binary or to compile from source depending on whether the ``BL32`` build
+option is specified or not.
+
+The TSP runs in Secure-EL1. It is designed to demonstrate synchronous
+communication with the normal-world software running in EL1/EL2. Communication
+is initiated by the normal-world software
+
+-  either directly through a Fast SMC (as defined in the `SMCCC`_)
+
+-  or indirectly through a `PSCI`_ SMC. The `PSCI`_ implementation in turn
+   informs the TSPD about the requested power management operation. This allows
+   the TSP to prepare for or respond to the power state change
+
+The TSPD service is responsible for.

+
+Initializing a BL32 Image
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The Secure-EL1 Payload Dispatcher (SPD) service is responsible for initializing
+the BL32 image. It needs access to the information passed by BL2 to BL31 to do
+so. This is provided by:
+
+.. code:: c
+
+    entry_point_info_t *bl31_plat_get_next_image_ep_info(uint32_t);
+
+which returns a reference to the ``entry_point_info`` structure corresponding to
+the image which will be run in the specified security state. The SPD uses this
+API to get entry point information for the SECURE image, BL32.
+
+In the absence of a BL32 image, BL31 passes control to the normal world
+bootloader image (BL33). When the BL32 image is present, it is typical
+that the SPD wants control to be passed to BL32 first and then later to BL33.
+
+To do this the SPD has to register a BL32 initialization function during
+initialization of the SPD service. The BL32 initialization function has this
+prototype:
+
+.. code:: c
+
+    int32_t init(void);
+
+and is registered using the ``bl31_register_bl32_init()`` function.
+
+TF-A supports two approaches for the SPD to pass control to BL32 before
+returning through EL3 and running the non-trusted firmware (BL33):
+
+#. In the BL32 setup function, use ``bl31_set_next_image_type()`` to
+   request that the exit from ``bl31_main()`` is to the BL32 entrypoint in
+   Secure-EL1. BL31 will exit to BL32 using the asynchronous method by
+   calling ``bl31_prepare_next_image_entry()`` and ``el3_exit()``.
+
+   When the BL32 has completed initialization at Secure-EL1, it returns to
+   BL31 by issuing an SMC, using a Function ID allocated to the SPD. On
+   receipt of this SMC, the SPD service handler should switch the CPU context
+   from trusted to normal world and use the ``bl31_set_next_image_type()`` and
+   ``bl31_prepare_next_image_entry()`` functions to set up the initial return to
+   the normal world firmware BL33. On return from the handler the framework
+   will exit to EL2 and run BL33.
+
+#. The BL32 setup function registers an initialization function using
+   ``bl31_register_bl32_init()`` which provides a SPD-defined mechanism to
+   invoke a 'world-switch synchronous call' to Secure-EL1 to run the BL32
+   entrypoint.
+
+   .. note::
+      The Test SPD service included with TF-A provides one implementation
+      of such a mechanism.
+
+   On completion BL32 returns control to BL31 via a SMC, and on receipt the
+   SPD service handler invokes the synchronous call return mechanism to return
+   to the BL32 initialization function. On return from this function,
+   ``bl31_main()`` will set up the return to the normal world firmware BL33 and
+   continue the boot process in the normal world.
+
+Crash Reporting in BL31
+-----------------------
+
+BL31 implements a scheme for reporting the processor state when an unhandled
+exception is encountered. The reporting mechanism attempts to preserve all the
+register contents and report it via a dedicated UART (PL011 console). BL31
+reports the general purpose, EL3, Secure EL1 and some EL2 state registers.
+
+A dedicated per-CPU crash stack is maintained by BL31 and this is retrieved via
+the per-CPU pointer cache. The implementation attempts to minimise the memory
+required for this feature. The file ``crash_reporting.S`` contains the
+implementation for crash reporting.
+
+The sample crash output is shown below.
+
+::
+
+    x0             = 0x000000002a4a0000

+
+Guidelines for Reset Handlers
+-----------------------------
+
+TF-A implements a framework that allows CPU and platform ports to perform
+actions very early after a CPU is released from reset in both the cold and warm
+boot paths. This is done by calling the ``reset_handler()`` function in both
+the BL1 and BL31 images. It in turn calls the platform and CPU specific reset
+handling functions.
+
+Details for implementing a CPU specific reset handler can be found in
+Section 8. Details for implementing a platform specific reset handler can be
+found in the :ref:`Porting Guide` (see the ``plat_reset_handler()`` function).
+
+When adding functionality to a reset handler, keep in mind that if a different
+reset handling behavior is required between the first and the subsequent
+invocations of the reset handling code, this should be detected at runtime.
+In other words, the reset handler should be able to detect whether an action has
+already been performed and act as appropriate. Possible courses of actions are,
+e.g. skip the action the second time, or undo/redo it.
+
+.. _configuring-secure-interrupts:
+
+Configuring secure interrupts
+-----------------------------
+
+The GIC driver is responsible for performing initial configuration of secure
+interrupts on the platform. To this end, the platform is expected to provide the
+GIC driver (either GICv2 or GICv3, as selected by the platform) with the
+interrupt configuration during the driver initialisation.
+
+Secure interrupt configuration are specified in an array of secure interrupt
+properties. In this scheme, in both GICv2 and GICv3 driver data structures, the
+``interrupt_props`` member points to an array of interrupt properties. Each
+element of the array specifies the interrupt number and its attributes
+(priority, group, configuration). Each element of the array shall be populated
+by the macro ``INTR_PROP_DESC()``. The macro takes the following arguments:
+
+- 10-bit interrupt number,
+
+- 8-bit interrupt priority,
+
+- Interrupt type (one of ``INTR_TYPE_EL3``, ``INTR_TYPE_S_EL1``,
+  ``INTR_TYPE_NS``),
+
+- Interrupt configuration (either ``GIC_INTR_CFG_LEVEL`` or
+  ``GIC_INTR_CFG_EDGE``).
+
+.. _firmware_design_cpu_ops_fwk:
+
+CPU specific operations framework
+---------------------------------
+
+Certain aspects of the Armv8-A architecture are implementation defined,
+that is, certain behaviours are not architecturally defined, but must be
+defined and documented by individual processor implementations. TF-A
+implements a framework which categorises the common implementation defined
+behaviours and allows a processor to export its implementation of that
+behaviour. The categories are:
+
+#. Processor specific reset sequence.
+
+#. Processor specific power down sequences.
+
+#. Processor specific register dumping as a part of crash reporting.
+
+#. Errata status reporting.
+
+Each of the above categories fulfils a different requirement.
+
+#. allows any processor specific initialization before the caches and MMU
+   are turned on, like implementation of errata workarounds, entry into
+   the intra-cluster coherency domain etc.
+
+#. allows each processor to implement the power down sequence mandated in
+   its Technical Reference Manual (TRM).
+
+#. allows a processor to provide additional information to the developer
+   in the event of a crash, for example Cortex-A53 has registers which
+   can expose the data cache contents.
+
+#. allows a processor to define a function that inspects and reports the status
+   of all errata workarounds on that processor.
+
+Please note that only 2. is mandated by the TRM.
+
+The CPU specific operations framework scales to accommodate a large number of
+different CPUs during power down and reset handling. The platform can specify
+any CPU optimization it wants to enable for each CPU. It can also specify
+the CPU errata workarounds to be applied for each CPU type during reset
+handling by defining CPU errata compile time macros. Details on these macros
+can be found in the :ref:`Arm CPU Specific Build Macros` document.
+
+The CPU specific operations framework depends on the ``cpu_ops`` structure which
+needs to be exported for each type of CPU in the platform. It is defined in
+``include/lib/cpus/aarch64/cpu_macros.S`` and has the following fields : ``midr``,
+``reset_func()``, ``cpu_pwr_down_ops`` (array of power down functions) and
+``cpu_reg_dump()``.
+
+The CPU specific files in ``lib/cpus`` export a ``cpu_ops`` data structure with
+suitable handlers for that CPU. For example, ``lib/cpus/aarch64/cortex_a53.S``
+exports the ``cpu_ops`` for Cortex-A53 CPU. According to the platform
+configuration, these CPU specific files must be included in the build by
+the platform makefile. The generic CPU specific operations framework code exists
+in ``lib/cpus/aarch64/cpu_helpers.S``.
+
+CPU specific Reset Handling
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+After a reset, the state of the CPU when it calls generic reset handler is:
+MMU turned off, both instruction and data caches turned off and not part
+of any coherency domain.
+
+The BL entrypoint code first invokes the ``plat_reset_handler()`` to allow
+the platform to perform any system initialization required and any system
+errata workarounds that needs to be applied. The ``get_cpu_ops_ptr()`` reads
+the current CPU midr, finds the matching ``cpu_ops`` entry in the ``cpu_ops``
+array and returns it. Note that only the part number and implementer fields
+in midr are used to find the matching ``cpu_ops`` entry. The ``reset_func()`` in
+the returned ``cpu_ops`` is then invoked which executes the required reset
+handling for that CPU and also any errata workarounds enabled by the platform.
+This function must preserve the values of general purpose registers x20 to x29.
+
+Refer to Section "Guidelines for Reset Handlers" for general guidelines
+regarding placement of code in a reset handler.
+
+CPU specific power down sequence
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+During the BL31 initialization sequence, the pointer to the matching ``cpu_ops``
+entry is stored in per-CPU data by ``init_cpu_ops()`` so that it can be quickly
+retrieved during power down sequences.
+
+Various CPU drivers register handlers to perform power down at certain power
+levels for that specific CPU. The PSCI service, upon receiving a power down
+request, determines the highest power level at which to execute power down
+sequence for a particular CPU. It uses the ``prepare_cpu_pwr_dwn()`` function to
+pick the right power down handler for the requested level. The function
+retrieves ``cpu_ops`` pointer member of per-CPU data, and from that, further
+retrieves ``cpu_pwr_down_ops`` array, and indexes into the required level. If the
+requested power level is higher than what a CPU driver supports, the handler
+registered for highest level is invoked.
+
+At runtime the platform hooks for power down are invoked by the PSCI service to
+perform platform specific operations during a power down sequence, for example
+turning off CCI coherency during a cluster power down.
+
+CPU specific register reporting during crash
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If the crash reporting is enabled in BL31, when a crash occurs, the crash
+reporting framework calls ``do_cpu_reg_dump`` which retrieves the matching
+``cpu_ops`` using ``get_cpu_ops_ptr()`` function. The ``cpu_reg_dump()`` in
+``cpu_ops`` is invoked, which then returns the CPU specific register values to
+be reported and a pointer to the ASCII list of register names in a format
+expected by the crash reporting framework.
+
+.. _firmware_design_cpu_errata_reporting:
+
+CPU errata status reporting
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Errata workarounds for CPUs supported in TF-A are applied during both cold and
+warm boots, shortly after reset. Individual Errata workarounds are enabled as
+build options. Some errata workarounds have potential run-time implications;
+therefore some are enabled by default, others not. Platform ports shall
+override build options to enable or disable errata as appropriate. The CPU
+drivers take care of applying errata workarounds that are enabled and applicable
+to a given CPU. Refer to :ref:`arm_cpu_macros_errata_workarounds` for more
+information.
+
+Functions in CPU drivers that apply errata workaround must follow the
+conventions listed below.
+
+The errata workaround must be authored as two separate functions:
+
+-  One that checks for errata. This function must determine whether that errata
+   applies to the current CPU. Typically this involves matching the current
+   CPUs revision and variant against a value that's known to be affected by the
+   errata. If the function determines that the errata applies to this CPU, it
+   must return ``ERRATA_APPLIES``; otherwise, it must return
+   ``ERRATA_NOT_APPLIES``. The utility functions ``cpu_get_rev_var`` and
+   ``cpu_rev_var_ls`` functions may come in handy for this purpose.
+
+For an errata identified as ``E``, the check function must be named
+``check_errata_E``.
+
+This function will be invoked at different times, both from assembly and from
+C run time. Therefore it must follow AAPCS, and must not use stack.
+
+-  Another one that applies the errata workaround. This function would call the
+   check function described above, and applies errata workaround if required.
+
+CPU drivers that apply errata workaround can optionally implement an assembly
+function that report the status of errata workarounds pertaining to that CPU.
+For a driver that registers the CPU, for example, ``cpux`` via ``declare_cpu_ops``
+macro, the errata reporting function, if it exists, must be named
+``cpux_errata_report``. This function will always be called with MMU enabled; it
+must follow AAPCS and may use stack.
+
+In a debug build of TF-A, on a CPU that comes out of reset, both BL1 and the
+runtime firmware (BL31 in AArch64, and BL32 in AArch32) will invoke errata
+status reporting function, if one exists, for that type of CPU.
+
+To report the status of each errata workaround, the function shall use the
+assembler macro ``report_errata``, passing it:
+
+-  The build option that enables the errata;
+
+-  The name of the CPU: this must be the same identifier that CPU driver
+   registered itself with, using ``declare_cpu_ops``;
+
+-  And the errata identifier: the identifier must match what's used in the
+   errata's check function described above.
+
+The errata status reporting function will be called once per CPU type/errata
+combination during the software's active life time.
+
+It's expected that whenever an errata workaround is submitted to TF-A, the
+errata reporting function is appropriately extended to report its status as
+well.
+
+Reporting the status of errata workaround is for informational purpose only; it
+has no functional significance.
+
+Memory layout of BL images
+--------------------------
+
+Each bootloader image can be divided in 2 parts:
+
+-  the static contents of the image. These are data actually stored in the
+   binary on the disk. In the ELF terminology, they are called ``PROGBITS``
+   sections;
+
+-  the run-time contents of the image. These are data that don't occupy any
+   space in the binary on the disk. The ELF binary just contains some
+   metadata indicating where these data will be stored at run-time and the
+   corresponding sections need to be allocated and initialized at run-time.
+   In the ELF terminology, they are called ``NOBITS`` sections.
+
+All PROGBITS sections are grouped together at the beginning of the image,
+followed by all NOBITS sections. This is true for all TF-A images and it is
+governed by the linker scripts. This ensures that the raw binary images are
+as small as possible. If a NOBITS section was inserted in between PROGBITS
+sections then the resulting binary file would contain zero bytes in place of
+this NOBITS section, making the image unnecessarily bigger. Smaller images
+allow faster loading from the FIP to the main memory.
+
+For BL31, a platform can specify an alternate location for NOBITS sections
+(other than immediately following PROGBITS sections) by setting
+``SEPARATE_NOBITS_REGION`` to 1 and defining ``BL31_NOBITS_BASE`` and
+``BL31_NOBITS_LIMIT``.
+
+Linker scripts and symbols
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Each bootloader stage image layout is described by its own linker script. The
+linker scripts export some symbols into the program symbol table. Their values
+correspond to particular addresses. TF-A code can refer to these symbols to
+figure out the image memory layout.
+
+Linker symbols follow the following naming convention in TF-A.
+
+-  ``__<SECTION>_START__``
+
+   Start address of a given section named ``<SECTION>``.
+
+-  ``__<SECTION>_END__``
+
+   End address of a given section named ``<SECTION>``. If there is an alignment
+   constraint on the section's end address then ``__<SECTION>_END__`` corresponds
+   to the end address of the section's actual contents, rounded up to the right
+   boundary. Refer to the value of ``__<SECTION>_UNALIGNED_END__`` to know the
+   actual end address of the section's contents.
+
+-  ``__<SECTION>_UNALIGNED_END__``
+
+   End address of a given section named ``<SECTION>`` without any padding or
+   rounding up due to some alignment constraint.
+
+-  ``__<SECTION>_SIZE__``
+
+   Size (in bytes) of a given section named ``<SECTION>``. If there is an
+   alignment constraint on the section's end address then ``__<SECTION>_SIZE__``
+   corresponds to the size of the section's actual contents, rounded up to the
+   right boundary. In other words, ``__<SECTION>_SIZE__ = __<SECTION>_END__ - _<SECTION>_START__``. Refer to the value of ``__<SECTION>_UNALIGNED_SIZE__``
+   to know the actual size of the section's contents.
+
+-  ``__<SECTION>_UNALIGNED_SIZE__``
+
+   Size (in bytes) of a given section named ``<SECTION>`` without any padding or
+   rounding up due to some alignment constraint. In other words,
+   ``__<SECTION>_UNALIGNED_SIZE__ = __<SECTION>_UNALIGNED_END__ - __<SECTION>_START__``.
+
+Some of the linker symbols are mandatory as TF-A code relies on them to be
+defined. They are listed in the following subsections. Some of them must be
+provided for each bootloader stage and some are specific to a given bootloader
+stage.
+
+The linker scripts define some extra, optional symbols. They are not actually
+used by any code but they help in understanding the bootloader images' memory
+layout as they are easy to spot in the link map files.
+
+Common linker symbols
+^^^^^^^^^^^^^^^^^^^^^
+
+All BL images share the following requirements:
+
+-  The BSS section must be zero-initialised before executing any C code.
+-  The coherent memory section (if enabled) must be zero-initialised as well.
+-  The MMU setup code needs to know the extents of the coherent and read-only
+   memory regions to set the right memory attributes. When
+   ``SEPARATE_CODE_AND_RODATA=1``, it needs to know more specifically how the
+   read-only memory region is divided between code and data.
+
+The following linker symbols are defined for this purpose:
+
+-  ``__BSS_START__``
+-  ``__BSS_SIZE__``
+-  ``__COHERENT_RAM_START__`` Must be aligned on a page-size boundary.
+-  ``__COHERENT_RAM_END__`` Must be aligned on a page-size boundary.
+-  ``__COHERENT_RAM_UNALIGNED_SIZE__``
+-  ``__RO_START__``
+-  ``__RO_END__``
+-  ``__TEXT_START__``
+-  ``__TEXT_END__``
+-  ``__RODATA_START__``
+-  ``__RODATA_END__``
+
+BL1's linker symbols
+^^^^^^^^^^^^^^^^^^^^
+
+BL1 being the ROM image, it has additional requirements. BL1 resides in ROM and
+it is entirely executed in place but it needs some read-write memory for its
+mutable data. Its ``.data`` section (i.e. its allocated read-write data) must be
+relocated from ROM to RAM before executing any C code.
+
+The following additional linker symbols are defined for BL1:
+
+-  ``__BL1_ROM_END__`` End address of BL1's ROM contents, covering its code

+
+How to choose the right base addresses for each bootloader stage image
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+There is currently no support for dynamic image loading in TF-A. This means
+that all bootloader images need to be linked against their ultimate runtime
+locations and the base addresses of each image must be chosen carefully such
+that images don't overlap each other in an undesired way. As the code grows,
+the base addresses might need adjustments to cope with the new memory layout.
+
+The memory layout is completely specific to the platform and so there is no
+general recipe for choosing the right base addresses for each bootloader image.
+However, there are tools to aid in understanding the memory layout. These are
+the link map files: ``build/<platform>/<build-type>/bl<x>/bl<x>.map``, with ``<x>``
+being the stage bootloader. They provide a detailed view of the memory usage of
+each image. Among other useful information, they provide the end address of
+each image.
+
+-  ``bl1.map`` link map file provides ``__BL1_RAM_END__`` address.
+-  ``bl2.map`` link map file provides ``__BL2_END__`` address.
+-  ``bl31.map`` link map file provides ``__BL31_END__`` address.
+-  ``bl32.map`` link map file provides ``__BL32_END__`` address.
+
+For each bootloader image, the platform code must provide its start address
+as well as a limit address that it must not overstep. The latter is used in the
+linker scripts to check that the image doesn't grow past that address. If that
+happens, the linker will issue a message similar to the following:
+
+::
+
+    aarch64-none-elf-ld: BLx has exceeded its limit.
+
+Additionally, if the platform memory layout implies some image overlaying like
+on FVP, BL31 and TSP need to know the limit address that their PROGBITS
+sections must not overstep. The platform code must provide those.
+
+TF-A does not provide any mechanism to verify at boot time that the memory
+to load a new image is free to prevent overwriting a previously loaded image.
+The platform must specify the memory available in the system for all the
+relevant BL images to be loaded.
+
+For example, in the case of BL1 loading BL2, ``bl1_plat_sec_mem_layout()`` will
+return the region defined by the platform where BL1 intends to load BL2. The
+``load_image()`` function performs bounds check for the image size based on the
+base and maximum image size provided by the platforms. Platforms must take
+this behaviour into account when defining the base/size for each of the images.
+
+Memory layout on Arm development platforms
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The following list describes the memory layout on the Arm development platforms:
+
+-  A 4KB page of shared memory is used for communication between Trusted
+   Firmware and the platform's power controller. This is located at the base of
+   Trusted SRAM. The amount of Trusted SRAM available to load the bootloader
+   images is reduced by the size of the shared memory.
+
+   The shared memory is used to store the CPUs' entrypoint mailbox. On Juno,
+   this is also used for the MHU payload when passing messages to and from the
+   SCP.
+
+-  Another 4 KB page is reserved for passing memory layout between BL1 and BL2
+   and also the dynamic firmware configurations.
+
+-  On FVP, BL1 is originally sitting in the Trusted ROM at address ``0x0``. On
+   Juno, BL1 resides in flash memory at address ``0x0BEC0000``. BL1 read-write
+   data are relocated to the top of Trusted SRAM at runtime.
+
+-  BL2 is loaded below BL1 RW
+
+-  EL3 Runtime Software, BL31 for AArch64 and BL32 for AArch32 (e.g. SP_MIN),
+   is loaded at the top of the Trusted SRAM, such that its NOBITS sections will
+   overwrite BL1 R/W data and BL2. This implies that BL1 global variables
+   remain valid only until execution reaches the EL3 Runtime Software entry
+   point during a cold boot.
+
+-  On Juno, SCP_BL2 is loaded temporarily into the EL3 Runtime Software memory
+   region and transferred to the SCP before being overwritten by EL3 Runtime
+   Software.
+
+-  BL32 (for AArch64) can be loaded in one of the following locations:
+
+   -  Trusted SRAM
+   -  Trusted DRAM (FVP only)
+   -  Secure region of DRAM (top 16MB of DRAM configured by the TrustZone
+      controller)
+
+   When BL32 (for AArch64) is loaded into Trusted SRAM, it is loaded below
+   BL31.
+
+The location of the BL32 image will result in different memory maps. This is
+illustrated for both FVP and Juno in the following diagrams, using the TSP as
+an example.
+
+.. note::
+   Loading the BL32 image in TZC secured DRAM doesn't change the memory
+   layout of the other images in Trusted SRAM.
+
+CONFIG section in memory layouts shown below contains:
+
+::
+
+    +--------------------+
+    |bl2_mem_params_descs|
+    |--------------------|
+    |     fw_configs     |
+    +--------------------+
+
+``bl2_mem_params_descs`` contains parameters passed from BL2 to next the
+BL image during boot.
+
+``fw_configs`` includes soc_fw_config, tos_fw_config, tb_fw_config and fw_config.

+
+Firmware Image Package (FIP)
+----------------------------
+
+Using a Firmware Image Package (FIP) allows for packing bootloader images (and
+potentially other payloads) into a single archive that can be loaded by TF-A
+from non-volatile platform storage. A driver to load images from a FIP has
+been added to the storage layer and allows a package to be read from supported
+platform storage. A tool to create Firmware Image Packages is also provided
+and described below.
+
+Firmware Image Package layout
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The FIP layout consists of a table of contents (ToC) followed by payload data.
+The ToC itself has a header followed by one or more table entries. The ToC is
+terminated by an end marker entry, and since the size of the ToC is 0 bytes,
+the offset equals the total size of the FIP file. All ToC entries describe some
+payload data that has been appended to the end of the binary package. With the
+information provided in the ToC entry the corresponding payload data can be
+retrieved.
+
+::
+
+    ------------------
+    | ToC Header     |
+    |----------------|
+    | ToC Entry 0    |
+    |----------------|
+    | ToC Entry 1    |
+    |----------------|
+    | ToC End Marker |
+    |----------------|
+    |                |
+    |     Data 0     |
+    |                |
+    |----------------|
+    |                |
+    |     Data 1     |
+    |                |
+    ------------------
+
+The ToC header and entry formats are described in the header file
+``include/tools_share/firmware_image_package.h``. This file is used by both the
+tool and TF-A.
+
+The ToC header has the following fields:
+
+::
+
+    `name`: The name of the ToC. This is currently used to validate the header.
+    `serial_number`: A non-zero number provided by the creation tool
+    `flags`: Flags associated with this data.
+        Bits 0-31: Reserved
+        Bits 32-47: Platform defined
+        Bits 48-63: Reserved
+
+A ToC entry has the following fields:
+
+::
+
+    `uuid`: All files are referred to by a pre-defined Universally Unique
+        IDentifier [UUID] . The UUIDs are defined in
+        `include/tools_share/firmware_image_package.h`. The platform translates
+        the requested image name into the corresponding UUID when accessing the
+        package.
+    `offset_address`: The offset address at which the corresponding payload data
+        can be found. The offset is calculated from the ToC base address.
+    `size`: The size of the corresponding payload data in bytes.
+    `flags`: Flags associated with this entry. None are yet defined.
+
+Firmware Image Package creation tool
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The FIP creation tool can be used to pack specified images into a binary
+package that can be loaded by TF-A from platform storage. The tool currently
+only supports packing bootloader images. Additional image definitions can be
+added to the tool as required.
+
+The tool can be found in ``tools/fiptool``.
+
+Loading from a Firmware Image Package (FIP)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The Firmware Image Package (FIP) driver can load images from a binary package on
+non-volatile platform storage. For the Arm development platforms, this is
+currently NOR FLASH.
+
+Bootloader images are loaded according to the platform policy as specified by
+the function ``plat_get_image_source()``. For the Arm development platforms, this
+means the platform will attempt to load images from a Firmware Image Package
+located at the start of NOR FLASH0.
+
+The Arm development platforms' policy is to only allow loading of a known set of
+images. The platform policy can be modified to allow additional images.
+
+Use of coherent memory in TF-A
+------------------------------
+
+There might be loss of coherency when physical memory with mismatched
+shareability, cacheability and memory attributes is accessed by multiple CPUs
+(refer to section B2.9 of `Arm ARM`_ for more details). This possibility occurs
+in TF-A during power up/down sequences when coherency, MMU and caches are
+turned on/off incrementally.
+
+TF-A defines coherent memory as a region of memory with Device nGnRE attributes
+in the translation tables. The translation granule size in TF-A is 4KB. This
+is the smallest possible size of the coherent memory region.
+
+By default, all data structures which are susceptible to accesses with
+mismatched attributes from various CPUs are allocated in a coherent memory
+region (refer to section 2.1 of :ref:`Porting Guide`). The coherent memory
+region accesses are Outer Shareable, non-cacheable and they can be accessed with
+the Device nGnRE attributes when the MMU is turned on. Hence, at the expense of
+at least an extra page of memory, TF-A is able to work around coherency issues
+due to mismatched memory attributes.
+
+The alternative to the above approach is to allocate the susceptible data
+structures in Normal WriteBack WriteAllocate Inner shareable memory. This
+approach requires the data structures to be designed so that it is possible to
+work around the issue of mismatched memory attributes by performing software
+cache maintenance on them.
+
+Disabling the use of coherent memory in TF-A
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+It might be desirable to avoid the cost of allocating coherent memory on
+platforms which are memory constrained. TF-A enables inclusion of coherent
+memory in firmware images through the build flag ``USE_COHERENT_MEM``.
+This flag is enabled by default. It can be disabled to choose the second
+approach described above.
+
+The below sections analyze the data structures allocated in the coherent memory
+region and the changes required to allocate them in normal memory.
+
+Coherent memory usage in PSCI implementation
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The ``psci_non_cpu_pd_nodes`` data structure stores the platform's power domain
+tree information for state management of power domains. By default, this data
+structure is allocated in the coherent memory region in TF-A because it can be
+accessed by multiple CPUs, either with caches enabled or disabled.

+         * Index of the parent power domain node.
+         */
+        unsigned int parent_node;
+
+        plat_local_state_t local_state;
+
+        unsigned char level;
+
+        /* For indexing the psci_lock array*/
+        unsigned char lock_index;
+    } non_cpu_pd_node_t;
+
+In order to move this data structure to normal memory, the use of each of its
+fields must be analyzed. Fields like ``cpu_start_idx``, ``ncpus``, ``parent_node``
+``level`` and ``lock_index`` are only written once during cold boot. Hence removing
+them from coherent memory involves only doing a clean and invalidate of the
+cache lines after these fields are written.
+
+The field ``local_state`` can be concurrently accessed by multiple CPUs in
+different cache states. A Lamport's Bakery lock ``psci_locks`` is used to ensure
+mutual exclusion to this field and a clean and invalidate is needed after it
+is written.
+
+Bakery lock data
+~~~~~~~~~~~~~~~~
+
+The bakery lock data structure ``bakery_lock_t`` is allocated in coherent memory
+and is accessed by multiple CPUs with mismatched attributes. ``bakery_lock_t`` is
+defined as follows:
+
+.. code:: c
+
+    typedef struct bakery_lock {
+        /*
+         * The lock_data is a bit-field of 2 members:
+         * Bit[0]       : choosing. This field is set when the CPU is
+         *                choosing its bakery number.
+         * Bits[1 - 15] : number. This is the bakery number allocated.
+         */
+        volatile uint16_t lock_data[BAKERY_LOCK_MAX_CPUS];
+    } bakery_lock_t;
+
+It is a characteristic of Lamport's Bakery algorithm that the volatile per-CPU
+fields can be read by all CPUs but only written to by the owning CPU.
+
+Depending upon the data cache line size, the per-CPU fields of the
+``bakery_lock_t`` structure for multiple CPUs may exist on a single cache line.
+These per-CPU fields can be read and written during lock contention by multiple
+CPUs with mismatched memory attributes. Since these fields are a part of the
+lock implementation, they do not have access to any other locking primitive to
+safeguard against the resulting coherency issues. As a result, simple software
+cache maintenance is not enough to allocate them in coherent memory. Consider
+the following example.
+
+CPU0 updates its per-CPU field with data cache enabled. This write updates a
+local cache line which contains a copy of the fields for other CPUs as well. Now
+CPU1 updates its per-CPU field of the ``bakery_lock_t`` structure with data cache
+disabled. CPU1 then issues a DCIVAC operation to invalidate any stale copies of
+its field in any other cache line in the system. This operation will invalidate
+the update made by CPU0 as well.
+
+To use bakery locks when ``USE_COHERENT_MEM`` is disabled, the lock data structure
+has been redesigned. The changes utilise the characteristic of Lamport's Bakery
+algorithm mentioned earlier. The bakery_lock structure only allocates the memory
+for a single CPU. The macro ``DEFINE_BAKERY_LOCK`` allocates all the bakery locks
+needed for a CPU into a section ``bakery_lock``. The linker allocates the memory
+for other cores by using the total size allocated for the bakery_lock section
+and multiplying it with (PLATFORM_CORE_COUNT - 1). This enables software to
+perform software cache maintenance on the lock data structure without running
+into coherency issues associated with mismatched attributes.
+
+The bakery lock data structure ``bakery_info_t`` is defined for use when
+``USE_COHERENT_MEM`` is disabled as follows:
+
+.. code:: c
+
+    typedef struct bakery_info {
+        /*
+         * The lock_data is a bit-field of 2 members:
+         * Bit[0]       : choosing. This field is set when the CPU is
+         *                choosing its bakery number.
+         * Bits[1 - 15] : number. This is the bakery number allocated.
+         */
+         volatile uint16_t lock_data;
+    } bakery_info_t;
+
+The ``bakery_info_t`` represents a single per-CPU field of one lock and
+the combination of corresponding ``bakery_info_t`` structures for all CPUs in the
+system represents the complete bakery lock. The view in memory for a system
+with n bakery locks are:
+
+::
+
+    bakery_lock section start
+    |----------------|
+    | `bakery_info_t`| <-- Lock_0 per-CPU field
+    |    Lock_0      |     for CPU0

+    |----------------|

+    |    XXXXX       |
+    | Padding to     |
+    | next Cache WB  |
+    |  Granule       |
+    ------------------
+
+Consider a system of 2 CPUs with 'N' bakery locks as shown above. For an
+operation on Lock_N, the corresponding ``bakery_info_t`` in both CPU0 and CPU1
+``bakery_lock`` section need to be fetched and appropriate cache operations need
+to be performed for each access.
+
+On Arm Platforms, bakery locks are used in psci (``psci_locks``) and power controller
+driver (``arm_lock``).
+
+Non Functional Impact of removing coherent memory
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Removal of the coherent memory region leads to the additional software overhead
+of performing cache maintenance for the affected data structures. However, since
+the memory where the data structures are allocated is cacheable, the overhead is
+mostly mitigated by an increase in performance.
+
+There is however a performance impact for bakery locks, due to:
+
+-  Additional cache maintenance operations, and
+-  Multiple cache line reads for each lock operation, since the bakery locks
+   for each CPU are distributed across different cache lines.
+
+The implementation has been optimized to minimize this additional overhead.
+Measurements indicate that when bakery locks are allocated in Normal memory, the
+minimum latency of acquiring a lock is on an average 3-4 micro seconds whereas
+in Device memory the same is 2 micro seconds. The measurements were done on the
+Juno Arm development platform.
+
+As mentioned earlier, almost a page of memory can be saved by disabling
+``USE_COHERENT_MEM``. Each platform needs to consider these trade-offs to decide
+whether coherent memory should be used. If a platform disables
+``USE_COHERENT_MEM`` and needs to use bakery locks in the porting layer, it can
+optionally define macro ``PLAT_PERCPU_BAKERY_LOCK_SIZE`` (see the
+:ref:`Porting Guide`). Refer to the reference platform code for examples.
+
+Isolating code and read-only data on separate memory pages
+----------------------------------------------------------
+
+In the Armv8-A VMSA, translation table entries include fields that define the
+properties of the target memory region, such as its access permissions. The
+smallest unit of memory that can be addressed by a translation table entry is
+a memory page. Therefore, if software needs to set different permissions on two
+memory regions then it needs to map them using different memory pages.
+
+The default memory layout for each BL image is as follows:
+
+::
+
+       |        ...        |
+       +-------------------+
+       |  Read-write data  |
+       +-------------------+ Page boundary
+       |     <Padding>     |
+       +-------------------+
+       | Exception vectors |
+       +-------------------+ 2 KB boundary
+       |     <Padding>     |
+       +-------------------+
+       |  Read-only data   |
+       +-------------------+
+       |       Code        |
+       +-------------------+ BLx_BASE
+
+.. note::
+   The 2KB alignment for the exception vectors is an architectural
+   requirement.
+
+The read-write data start on a new memory page so that they can be mapped with
+read-write permissions, whereas the code and read-only data below are configured
+as read-only.
+
+However, the read-only data are not aligned on a page boundary. They are
+contiguous to the code. Therefore, the end of the code section and the beginning
+of the read-only data one might share a memory page. This forces both to be
+mapped with the same memory attributes. As the code needs to be executable, this
+means that the read-only data stored on the same memory page as the code are
+executable as well. This could potentially be exploited as part of a security
+attack.
+
+TF provides the build flag ``SEPARATE_CODE_AND_RODATA`` to isolate the code and
+read-only data on separate memory pages. This in turn allows independent control
+of the access permissions for the code and read-only data. In this case,
+platform code gets a finer-grained view of the image layout and can
+appropriately map the code region as executable and the read-only data as
+execute-never.
+
+This has an impact on memory footprint, as padding bytes need to be introduced
+between the code and read-only data to ensure the segregation of the two. To
+limit the memory cost, this flag also changes the memory layout such that the
+code and exception vectors are now contiguous, like so:
+
+::
+
+       |        ...        |
+       +-------------------+
+       |  Read-write data  |
+       +-------------------+ Page boundary
+       |     <Padding>     |
+       +-------------------+
+       |  Read-only data   |
+       +-------------------+ Page boundary
+       |     <Padding>     |
+       +-------------------+
+       | Exception vectors |
+       +-------------------+ 2 KB boundary
+       |     <Padding>     |
+       +-------------------+
+       |       Code        |
+       +-------------------+ BLx_BASE
+
+With this more condensed memory layout, the separation of read-only data will
+add zero or one page to the memory footprint of each BL image. Each platform
+should consider the trade-off between memory footprint and security.
+
+This build flag is disabled by default, minimising memory footprint. On Arm
+platforms, it is enabled.
+
+Publish and Subscribe Framework
+-------------------------------
+
+The Publish and Subscribe Framework allows EL3 components to define and publish
+events, to which other EL3 components can subscribe.
+
+The following macros are provided by the framework:
+
+-  ``REGISTER_PUBSUB_EVENT(event)``: Defines an event, and takes one argument,
+   the event name, which must be a valid C identifier. All calls to
+   ``REGISTER_PUBSUB_EVENT`` macro must be placed in the file
+   ``pubsub_events.h``.
+
+-  ``PUBLISH_EVENT_ARG(event, arg)``: Publishes a defined event, by iterating
+   subscribed handlers and calling them in turn. The handlers will be passed the
+   parameter ``arg``. The expected use-case is to broadcast an event.
+
+-  ``PUBLISH_EVENT(event)``: Like ``PUBLISH_EVENT_ARG``, except that the value
+   ``NULL`` is passed to subscribed handlers.
+
+-  ``SUBSCRIBE_TO_EVENT(event, handler)``: Registers the ``handler`` to
+   subscribe to ``event``. The handler will be executed whenever the ``event``
+   is published.
+
+-  ``for_each_subscriber(event, subscriber)``: Iterates through all handlers
+   subscribed for ``event``. ``subscriber`` must be a local variable of type
+   ``pubsub_cb_t *``, and will point to each subscribed handler in turn during
+   iteration. This macro can be used for those patterns that none of the
+   ``PUBLISH_EVENT_*()`` macros cover.
+
+Publishing an event that wasn't defined using ``REGISTER_PUBSUB_EVENT`` will
+result in build error. Subscribing to an undefined event however won't.
+
+Subscribed handlers must be of type ``pubsub_cb_t``, with following function
+signature:
+
+.. code:: c
+
+   typedef void* (*pubsub_cb_t)(const void *arg);
+
+There may be arbitrary number of handlers registered to the same event. The
+order in which subscribed handlers are notified when that event is published is
+not defined. Subscribed handlers may be executed in any order; handlers should
+not assume any relative ordering amongst them.
+
+Publishing an event on a PE will result in subscribed handlers executing on that
+PE only; it won't cause handlers to execute on a different PE.
+
+Note that publishing an event on a PE blocks until all the subscribed handlers
+finish executing on the PE.
+
+TF-A generic code publishes and subscribes to some events within. Platform
+ports are discouraged from subscribing to them. These events may be withdrawn,
+renamed, or have their semantics altered in the future. Platforms may however
+register, publish, and subscribe to platform-specific events.
+
+Publish and Subscribe Example
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+A publisher that wants to publish event ``foo`` would:
+
+-  Define the event ``foo`` in the ``pubsub_events.h``.
+
+   .. code:: c
+
+      REGISTER_PUBSUB_EVENT(foo);
+
+-  Depending on the nature of event, use one of ``PUBLISH_EVENT_*()`` macros to
+   publish the event at the appropriate path and time of execution.
+
+A subscriber that wants to subscribe to event ``foo`` published above would
+implement:
+
+.. code:: c
+
+    void *foo_handler(const void *arg)
+    {
+         void *result;
+
+         /* Do handling ... */
+
+         return result;
+    }
+
+    SUBSCRIBE_TO_EVENT(foo, foo_handler);
+
+
+Reclaiming the BL31 initialization code
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+A significant amount of the code used for the initialization of BL31 is never
+needed again after boot time. In order to reduce the runtime memory
+footprint, the memory used for this code can be reclaimed after initialization
+has finished and be used for runtime data.
+
+The build option ``RECLAIM_INIT_CODE`` can be set to mark this boot time code
+with a ``.text.init.*`` attribute which can be filtered and placed suitably
+within the BL image for later reclamation by the platform. The platform can
+specify the filter and the memory region for this init section in BL31 via the
+plat.ld.S linker script. For example, on the FVP, this section is placed
+overlapping the secondary CPU stacks so that after the cold boot is done, this
+memory can be reclaimed for the stacks. The init memory section is initially
+mapped with ``RO``, ``EXECUTE`` attributes. After BL31 initialization has
+completed, the FVP changes the attributes of this section to ``RW``,
+``EXECUTE_NEVER`` allowing it to be used for runtime data. The memory attributes
+are changed within the ``bl31_plat_runtime_setup`` platform hook. The init
+section section can be reclaimed for any data which is accessed after cold
+boot initialization and it is upto the platform to make the decision.

+
+Performance Measurement Framework
+---------------------------------
+
+The Performance Measurement Framework (PMF) facilitates collection of
+timestamps by registered services and provides interfaces to retrieve them
+from within TF-A. A platform can choose to expose appropriate SMCs to
+retrieve these collected timestamps.
+
+By default, the global physical counter is used for the timestamp
+value and is read via ``CNTPCT_EL0``. The framework allows to retrieve
+timestamps captured by other CPUs.
+
+Timestamp identifier format
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+A PMF timestamp is uniquely identified across the system via the
+timestamp ID or ``tid``. The ``tid`` is composed as follows:
+
+::
+
+    Bits 0-7: The local timestamp identifier.
+    Bits 8-9: Reserved.
+    Bits 10-15: The service identifier.
+    Bits 16-31: Reserved.
+
+#. The service identifier. Each PMF service is identified by a
+   service name and a service identifier. Both the service name and
+   identifier are unique within the system as a whole.
+
+#. The local timestamp identifier. This identifier is unique within a given
+   service.
+
+Registering a PMF service
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+To register a PMF service, the ``PMF_REGISTER_SERVICE()`` macro from ``pmf.h``
+is used. The arguments required are the service name, the service ID,
+the total number of local timestamps to be captured and a set of flags.
+
+The ``flags`` field can be specified as a bitwise-OR of the following values:
+
+::
+
+    PMF_STORE_ENABLE: The timestamp is stored in memory for later retrieval.
+    PMF_DUMP_ENABLE: The timestamp is dumped on the serial console.
+
+The ``PMF_REGISTER_SERVICE()`` reserves memory to store captured
+timestamps in a PMF specific linker section at build time.
+Additionally, it defines necessary functions to capture and
+retrieve a particular timestamp for the given service at runtime.
+
+The macro ``PMF_REGISTER_SERVICE()`` only enables capturing PMF timestamps
+from within TF-A. In order to retrieve timestamps from outside of TF-A, the
+``PMF_REGISTER_SERVICE_SMC()`` macro must be used instead. This macro
+accepts the same set of arguments as the ``PMF_REGISTER_SERVICE()``
+macro but additionally supports retrieving timestamps using SMCs.
+
+Capturing a timestamp
+~~~~~~~~~~~~~~~~~~~~~
+
+PMF timestamps are stored in a per-service timestamp region. On a
+system with multiple CPUs, each timestamp is captured and stored
+in a per-CPU cache line aligned memory region.
+
+Having registered the service, the ``PMF_CAPTURE_TIMESTAMP()`` macro can be
+used to capture a timestamp at the location where it is used. The macro
+takes the service name, a local timestamp identifier and a flag as arguments.
+
+The ``flags`` field argument can be zero, or ``PMF_CACHE_MAINT`` which
+instructs PMF to do cache maintenance following the capture. Cache
+maintenance is required if any of the service's timestamps are captured
+with data cache disabled.
+
+To capture a timestamp in assembly code, the caller should use
+``pmf_calc_timestamp_addr`` macro (defined in ``pmf_asm_macros.S``) to
+calculate the address of where the timestamp would be stored. The
+caller should then read ``CNTPCT_EL0`` register to obtain the timestamp
+and store it at the determined address for later retrieval.
+
+Retrieving a timestamp
+~~~~~~~~~~~~~~~~~~~~~~
+
+From within TF-A, timestamps for individual CPUs can be retrieved using either
+``PMF_GET_TIMESTAMP_BY_MPIDR()`` or ``PMF_GET_TIMESTAMP_BY_INDEX()`` macros.
+These macros accept the CPU's MPIDR value, or its ordinal position
+respectively.
+
+From outside TF-A, timestamps for individual CPUs can be retrieved by calling
+into ``pmf_smc_handler()``.
+
+::
+
+    Interface : pmf_smc_handler()
+    Argument  : unsigned int smc_fid, u_register_t x1,
+                u_register_t x2, u_register_t x3,
+                u_register_t x4, void *cookie,
+                void *handle, u_register_t flags
+    Return    : uintptr_t
+
+    smc_fid: Holds the SMC identifier which is either `PMF_SMC_GET_TIMESTAMP_32`
+        when the caller of the SMC is running in AArch32 mode
+        or `PMF_SMC_GET_TIMESTAMP_64` when the caller is running in AArch64 mode.
+    x1: Timestamp identifier.
+    x2: The `mpidr` of the CPU for which the timestamp has to be retrieved.
+        This can be the `mpidr` of a different core to the one initiating
+        the SMC.  In that case, service specific cache maintenance may be
+        required to ensure the updated copy of the timestamp is returned.
+    x3: A flags value that is either 0 or `PMF_CACHE_MAINT`.  If
+        `PMF_CACHE_MAINT` is passed, then the PMF code will perform a
+        cache invalidate before reading the timestamp.  This ensures
+        an updated copy is returned.
+
+The remaining arguments, ``x4``, ``cookie``, ``handle`` and ``flags`` are unused
+in this implementation.
+
+PMF code structure
+~~~~~~~~~~~~~~~~~~
+
+#. ``pmf_main.c`` consists of core functions that implement service registration,
+   initialization, storing, dumping and retrieving timestamps.
+
+#. ``pmf_smc.c`` contains the SMC handling for registered PMF services.
+
+#. ``pmf.h`` contains the public interface to Performance Measurement Framework.
+
+#. ``pmf_asm_macros.S`` consists of macros to facilitate capturing timestamps in
+   assembly code.
+
+#. ``pmf_helpers.h`` is an internal header used by ``pmf.h``.
+
+Armv8-A Architecture Extensions
+-------------------------------
+
+TF-A makes use of Armv8-A Architecture Extensions where applicable. This
+section lists the usage of Architecture Extensions, and build flags
+controlling them.
+
+In general, and unless individually mentioned, the build options
+``ARM_ARCH_MAJOR`` and ``ARM_ARCH_MINOR`` select the Architecture Extension to
+target when building TF-A. Subsequent Arm Architecture Extensions are backward
+compatible with previous versions.
+
+The build system only requires that ``ARM_ARCH_MAJOR`` and ``ARM_ARCH_MINOR`` have a
+valid numeric value. These build options only control whether or not
+Architecture Extension-specific code is included in the build. Otherwise, TF-A
+targets the base Armv8.0-A architecture; i.e. as if ``ARM_ARCH_MAJOR`` == 8
+and ``ARM_ARCH_MINOR`` == 0, which are also their respective default values.
+
+.. seealso:: :ref:`Build Options`
+
+For details on the Architecture Extension and available features, please refer
+to the respective Architecture Extension Supplement.
+
+Armv8.1-A
+~~~~~~~~~
+
+This Architecture Extension is targeted when ``ARM_ARCH_MAJOR`` >= 8, or when
+``ARM_ARCH_MAJOR`` == 8 and ``ARM_ARCH_MINOR`` >= 1.
+
+-  By default, a load-/store-exclusive instruction pair is used to implement
+   spinlocks. The ``USE_SPINLOCK_CAS`` build option when set to 1 selects the
+   spinlock implementation using the ARMv8.1-LSE Compare and Swap instruction.
+   Notice this instruction is only available in AArch64 execution state, so
+   the option is only available to AArch64 builds.
+
+Armv8.2-A
+~~~~~~~~~
+
+-  The presence of ARMv8.2-TTCNP is detected at runtime. When it is present, the
+   Common not Private (TTBRn_ELx.CnP) bit is enabled to indicate that multiple
+   Processing Elements in the same Inner Shareable domain use the same
+   translation table entries for a given stage of translation for a particular
+   translation regime.
+
+Armv8.3-A
+~~~~~~~~~
+
+-  Pointer authentication features of Armv8.3-A are unconditionally enabled in
+   the Non-secure world so that lower ELs are allowed to use them without
+   causing a trap to EL3.
+
+   In order to enable the Secure world to use it, ``CTX_INCLUDE_PAUTH_REGS``
+   must be set to 1. This will add all pointer authentication system registers
+   to the context that is saved when doing a world switch.
+
+   The TF-A itself has support for pointer authentication at runtime
+   that can be enabled by setting ``BRANCH_PROTECTION`` option to non-zero and
+   ``CTX_INCLUDE_PAUTH_REGS`` to 1. This enables pointer authentication in BL1,
+   BL2, BL31, and the TSP if it is used.
+
+   Note that Pointer Authentication is enabled for Non-secure world irrespective
+   of the value of these build flags if the CPU supports it.
+
+   If ``ARM_ARCH_MAJOR == 8`` and ``ARM_ARCH_MINOR >= 3`` the code footprint of
+   enabling PAuth is lower because the compiler will use the optimized
+   PAuth instructions rather than the backwards-compatible ones.
+
+Armv8.5-A
+~~~~~~~~~
+
+-  Branch Target Identification feature is selected by ``BRANCH_PROTECTION``
+   option set to 1. This option defaults to 0.
+
+-  Memory Tagging Extension feature is unconditionally enabled for both worlds
+   (at EL0 and S-EL0) if it is only supported at EL0. If instead it is
+   implemented at all ELs, it is unconditionally enabled for only the normal
+   world. To enable it for the secure world as well, the build option
+   ``CTX_INCLUDE_MTE_REGS`` is required. If the hardware does not implement
+   MTE support at all, it is always disabled, no matter what build options
+   are used.
+
+Armv7-A
+~~~~~~~
+
+This Architecture Extension is targeted when ``ARM_ARCH_MAJOR`` == 7.
+
+There are several Armv7-A extensions available. Obviously the TrustZone
+extension is mandatory to support the TF-A bootloader and runtime services.
+
+Platform implementing an Armv7-A system can to define from its target
+Cortex-A architecture through ``ARM_CORTEX_A<X> = yes`` in their
+``platform.mk`` script. For example ``ARM_CORTEX_A15=yes`` for a
+Cortex-A15 target.
+
+Platform can also set ``ARM_WITH_NEON=yes`` to enable neon support.
+Note that using neon at runtime has constraints on non secure world context.
+TF-A does not yet provide VFP context management.
+
+Directive ``ARM_CORTEX_A<x>`` and ``ARM_WITH_NEON`` are used to set
+the toolchain  target architecture directive.
+
+Platform may choose to not define straight the toolchain target architecture
+directive by defining ``MARCH32_DIRECTIVE``.
+I.e:
+
+.. code:: make
+
+   MARCH32_DIRECTIVE := -mach=armv7-a
+
+Code Structure
+--------------
+
+TF-A code is logically divided between the three boot loader stages mentioned
+in the previous sections. The code is also divided into the following
+categories (present as directories in the source code):
+

+Interrupt Management Framework 
+==============================
+
+This framework is responsible for managing interrupts routed to EL3. It also
+allows EL3 software to configure the interrupt routing behavior. Its main
+objective is to implement the following two requirements.
+
+#. It should be possible to route interrupts meant to be handled by secure
+   software (Secure interrupts) to EL3, when execution is in non-secure state
+   (normal world). The framework should then take care of handing control of
+   the interrupt to either software in EL3 or Secure-EL1 depending upon the
+   software configuration and the GIC implementation. This requirement ensures
+   that secure interrupts are under the control of the secure software with
+   respect to their delivery and handling without the possibility of
+   intervention from non-secure software.
+
+#. It should be possible to route interrupts meant to be handled by
+   non-secure software (Non-secure interrupts) to the last executed exception
+   level in the normal world when the execution is in secure world at
+   exception levels lower than EL3. This could be done with or without the
+   knowledge of software executing in Secure-EL1/Secure-EL0. The choice of
+   approach should be governed by the secure software. This requirement
+   ensures that non-secure software is able to execute in tandem with the
+   secure software without overriding it.
+
+Concepts
+--------
+
+Interrupt types
+~~~~~~~~~~~~~~~
+
+The framework categorises an interrupt to be one of the following depending upon
+the exception level(s) it is handled in.
+
+#. Secure EL1 interrupt. This type of interrupt can be routed to EL3 or
+   Secure-EL1 depending upon the security state of the current execution
+   context. It is always handled in Secure-EL1.
+
+#. Non-secure interrupt. This type of interrupt can be routed to EL3,
+   Secure-EL1, Non-secure EL1 or EL2 depending upon the security state of the
+   current execution context. It is always handled in either Non-secure EL1
+   or EL2.
+
+#. EL3 interrupt. This type of interrupt can be routed to EL3 or Secure-EL1
+   depending upon the security state of the current execution context. It is
+   always handled in EL3.
+
+The following constants define the various interrupt types in the framework
+implementation.
+
+.. code:: c
+
+    #define INTR_TYPE_S_EL1      0
+    #define INTR_TYPE_EL3        1
+    #define INTR_TYPE_NS         2
+
+Routing model
+~~~~~~~~~~~~~
+
+A type of interrupt can be either generated as an FIQ or an IRQ. The target
+exception level of an interrupt type is configured through the FIQ and IRQ bits
+in the Secure Configuration Register at EL3 (``SCR_EL3.FIQ`` and ``SCR_EL3.IRQ``
+bits). When ``SCR_EL3.FIQ``\ =1, FIQs are routed to EL3. Otherwise they are routed
+to the First Exception Level (FEL) capable of handling interrupts. When
+``SCR_EL3.IRQ``\ =1, IRQs are routed to EL3. Otherwise they are routed to the
+FEL. This register is configured independently by EL3 software for each security
+state prior to entry into a lower exception level in that security state.
+
+A routing model for a type of interrupt (generated as FIQ or IRQ) is defined as
+its target exception level for each security state. It is represented by a
+single bit for each security state. A value of ``0`` means that the interrupt
+should be routed to the FEL. A value of ``1`` means that the interrupt should be
+routed to EL3. A routing model is applicable only when execution is not in EL3.
+
+The default routing model for an interrupt type is to route it to the FEL in
+either security state.
+
+Valid routing models
+~~~~~~~~~~~~~~~~~~~~
+
+The framework considers certain routing models for each type of interrupt to be
+incorrect as they conflict with the requirements mentioned in Section 1. The
+following sub-sections describe all the possible routing models and specify
+which ones are valid or invalid. EL3 interrupts are currently supported only
+for GIC version 3.0 (Arm GICv3) and only the Secure-EL1 and Non-secure interrupt
+types are supported for GIC version 2.0 (Arm GICv2) (see `Assumptions in
+Interrupt Management Framework`_). The terminology used in the following
+sub-sections is explained below.
+
+#. **CSS**. Current Security State. ``0`` when secure and ``1`` when non-secure
+
+#. **TEL3**. Target Exception Level 3. ``0`` when targeted to the FEL. ``1`` when
+   targeted to EL3.
+
+Secure-EL1 interrupts
+^^^^^^^^^^^^^^^^^^^^^
+
+#. **CSS=0, TEL3=0**. Interrupt is routed to the FEL when execution is in
+   secure state. This is a valid routing model as secure software is in
+   control of handling secure interrupts.
+
+#. **CSS=0, TEL3=1**. Interrupt is routed to EL3 when execution is in secure
+   state. This is a valid routing model as secure software in EL3 can
+   handover the interrupt to Secure-EL1 for handling.
+
+#. **CSS=1, TEL3=0**. Interrupt is routed to the FEL when execution is in
+   non-secure state. This is an invalid routing model as a secure interrupt
+   is not visible to the secure software which violates the motivation behind
+   the Arm Security Extensions.
+
+#. **CSS=1, TEL3=1**. Interrupt is routed to EL3 when execution is in
+   non-secure state. This is a valid routing model as secure software in EL3
+   can handover the interrupt to Secure-EL1 for handling.
+
+Non-secure interrupts
+^^^^^^^^^^^^^^^^^^^^^
+
+#. **CSS=0, TEL3=0**. Interrupt is routed to the FEL when execution is in
+   secure state. This allows the secure software to trap non-secure
+   interrupts, perform its book-keeping and hand the interrupt to the
+   non-secure software through EL3. This is a valid routing model as secure
+   software is in control of how its execution is preempted by non-secure
+   interrupts.
+
+#. **CSS=0, TEL3=1**. Interrupt is routed to EL3 when execution is in secure
+   state. This is a valid routing model as secure software in EL3 can save
+   the state of software in Secure-EL1/Secure-EL0 before handing the
+   interrupt to non-secure software. This model requires additional
+   coordination between Secure-EL1 and EL3 software to ensure that the
+   former's state is correctly saved by the latter.
+
+#. **CSS=1, TEL3=0**. Interrupt is routed to FEL when execution is in
+   non-secure state. This is a valid routing model as a non-secure interrupt
+   is handled by non-secure software.
+
+#. **CSS=1, TEL3=1**. Interrupt is routed to EL3 when execution is in
+   non-secure state. This is an invalid routing model as there is no valid
+   reason to route the interrupt to EL3 software and then hand it back to
+   non-secure software for handling.
+
+.. _EL3 interrupts:
+
+EL3 interrupts
+^^^^^^^^^^^^^^
+
+#. **CSS=0, TEL3=0**. Interrupt is routed to the FEL when execution is in
+   Secure-EL1/Secure-EL0. This is a valid routing model as secure software
+   in Secure-EL1/Secure-EL0 is in control of how its execution is preempted
+   by EL3 interrupt and can handover the interrupt to EL3 for handling.
+
+   However, when ``EL3_EXCEPTION_HANDLING`` is ``1``, this routing model is
+   invalid as EL3 interrupts are unconditionally routed to EL3, and EL3
+   interrupts will always preempt Secure EL1/EL0 execution. See :ref:`exception
+   handling<interrupt-handling>` documentation.
+
+#. **CSS=0, TEL3=1**. Interrupt is routed to EL3 when execution is in
+   Secure-EL1/Secure-EL0. This is a valid routing model as secure software
+   in EL3 can handle the interrupt.
+
+#. **CSS=1, TEL3=0**. Interrupt is routed to the FEL when execution is in
+   non-secure state. This is an invalid routing model as a secure interrupt
+   is not visible to the secure software which violates the motivation behind
+   the Arm Security Extensions.
+
+#. **CSS=1, TEL3=1**. Interrupt is routed to EL3 when execution is in
+   non-secure state. This is a valid routing model as secure software in EL3
+   can handle the interrupt.
+
+Mapping of interrupt type to signal
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The framework is meant to work with any interrupt controller implemented by a
+platform. A interrupt controller could generate a type of interrupt as either an
+FIQ or IRQ signal to the CPU depending upon the current security state. The
+mapping between the type and signal is known only to the platform. The framework
+uses this information to determine whether the IRQ or the FIQ bit should be
+programmed in ``SCR_EL3`` while applying the routing model for a type of
+interrupt. The platform provides this information through the
+``plat_interrupt_type_to_line()`` API (described in the
+:ref:`Porting Guide`). For example, on the FVP port when the platform uses an
+Arm GICv2 interrupt controller, Secure-EL1 interrupts are signaled through the
+FIQ signal while Non-secure interrupts are signaled through the IRQ signal.
+This applies when execution is in either security state.
+
+Effect of mapping of several interrupt types to one signal
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+It should be noted that if more than one interrupt type maps to a single
+interrupt signal, and if any one of the interrupt type sets **TEL3=1** for a
+particular security state, then interrupt signal will be routed to EL3 when in
+that security state. This means that all the other interrupt types using the
+same interrupt signal will be forced to the same routing model. This should be
+borne in mind when choosing the routing model for an interrupt type.
+
+For example, in Arm GICv3, when the execution context is Secure-EL1/
+Secure-EL0, both the EL3 and the non secure interrupt types map to the FIQ
+signal. So if either one of the interrupt type sets the routing model so
+that **TEL3=1** when **CSS=0**, the FIQ bit in ``SCR_EL3`` will be programmed to
+route the FIQ signal to EL3 when executing in Secure-EL1/Secure-EL0, thereby
+effectively routing the other interrupt type also to EL3.
+
+Assumptions in Interrupt Management Framework
+---------------------------------------------
+
+The framework makes the following assumptions to simplify its implementation.
+
+#. Although the framework has support for 2 types of secure interrupts (EL3
+   and Secure-EL1 interrupt), only interrupt controller architectures
+   like Arm GICv3 has architectural support for EL3 interrupts in the form of
+   Group 0 interrupts. In Arm GICv2, all secure interrupts are assumed to be
+   handled in Secure-EL1. They can be delivered to Secure-EL1 via EL3 but they
+   cannot be handled in EL3.
+
+#. Interrupt exceptions (``PSTATE.I`` and ``F`` bits) are masked during execution
+   in EL3.
+
+#. Interrupt management: the following sections describe how interrupts are
+   managed by the interrupt handling framework. This entails:
+
+   #. Providing an interface to allow registration of a handler and
+      specification of the routing model for a type of interrupt.
+
+   #. Implementing support to hand control of an interrupt type to its
+      registered handler when the interrupt is generated.
+
+Both aspects of interrupt management involve various components in the secure
+software stack spanning from EL3 to Secure-EL1. These components are described
+in the section `Software components`_. The framework stores information
+associated with each type of interrupt in the following data structure.
+
+.. code:: c
+
+    typedef struct intr_type_desc {
+            interrupt_type_handler_t handler;
+            uint32_t flags;
+            uint32_t scr_el3[2];
+    } intr_type_desc_t;
+
+The ``flags`` field stores the routing model for the interrupt type in
+bits[1:0]. Bit[0] stores the routing model when execution is in the secure
+state. Bit[1] stores the routing model when execution is in the non-secure
+state. As mentioned in Section `Routing model`_, a value of ``0`` implies that
+the interrupt should be targeted to the FEL. A value of ``1`` implies that it
+should be targeted to EL3. The remaining bits are reserved and SBZ. The helper
+macro ``set_interrupt_rm_flag()`` should be used to set the bits in the
+``flags`` parameter.
+
+The ``scr_el3[2]`` field also stores the routing model but as a mapping of the
+model in the ``flags`` field to the corresponding bit in the ``SCR_EL3`` for each
+security state.
+
+The framework also depends upon the platform port to configure the interrupt
+controller to distinguish between secure and non-secure interrupts. The platform
+is expected to be aware of the secure devices present in the system and their
+associated interrupt numbers. It should configure the interrupt controller to
+enable the secure interrupts, ensure that their priority is always higher than
+the non-secure interrupts and target them to the primary CPU. It should also
+export the interface described in the :ref:`Porting Guide` to enable
+handling of interrupts.
+
+In the remainder of this document, for the sake of simplicity a Arm GICv2 system
+is considered and it is assumed that the FIQ signal is used to generate Secure-EL1
+interrupts and the IRQ signal is used to generate non-secure interrupts in either
+security state. EL3 interrupts are not considered.
+
+Software components
+-------------------
+
+Roles and responsibilities for interrupt management are sub-divided between the
+following components of software running in EL3 and Secure-EL1. Each component is
+briefly described below.
+
+#. EL3 Runtime Firmware. This component is common to all ports of TF-A.
+
+#. Secure Payload Dispatcher (SPD) service. This service interfaces with the
+   Secure Payload (SP) software which runs in Secure-EL1/Secure-EL0 and is
+   responsible for switching execution between secure and non-secure states.
+   A switch is triggered by a Secure Monitor Call and it uses the APIs
+   exported by the Context management library to implement this functionality.
+   Switching execution between the two security states is a requirement for
+   interrupt management as well. This results in a significant dependency on
+   the SPD service. TF-A implements an example Test Secure Payload Dispatcher
+   (TSPD) service.
+
+   An SPD service plugs into the EL3 runtime firmware and could be common to
+   some ports of TF-A.
+
+#. Secure Payload (SP). On a production system, the Secure Payload corresponds
+   to a Secure OS which runs in Secure-EL1/Secure-EL0. It interfaces with the
+   SPD service to manage communication with non-secure software. TF-A
+   implements an example secure payload called Test Secure Payload (TSP)
+   which runs only in Secure-EL1.
+
+   A Secure payload implementation could be common to some ports of TF-A,
+   just like the SPD service.
+
+Interrupt registration
+----------------------
+
+This section describes in detail the role of each software component (see
+`Software components`_) during the registration of a handler for an interrupt
+type.
+
+.. _el3-runtime-firmware:
+
+EL3 runtime firmware
+~~~~~~~~~~~~~~~~~~~~
+
+This component declares the following prototype for a handler of an interrupt type.
+
+.. code:: c
+
+        typedef uint64_t (*interrupt_type_handler_t)(uint32_t id,
+                                                     uint32_t flags,
+                                                     void *handle,
+                                                     void *cookie);
+
+The ``id`` is parameter is reserved and could be used in the future for passing
+the interrupt id of the highest pending interrupt only if there is a foolproof
+way of determining the id. Currently it contains ``INTR_ID_UNAVAILABLE``.
+
+The ``flags`` parameter contains miscellaneous information as follows.
+
+#. Security state, bit[0]. This bit indicates the security state of the lower
+   exception level when the interrupt was generated. A value of ``1`` means
+   that it was in the non-secure state. A value of ``0`` indicates that it was
+   in the secure state. This bit can be used by the handler to ensure that
+   interrupt was generated and routed as per the routing model specified
+   during registration.
+
+#. Reserved, bits[31:1]. The remaining bits are reserved for future use.
+
+The ``handle`` parameter points to the ``cpu_context`` structure of the current CPU
+for the security state specified in the ``flags`` parameter.
+
+Once the handler routine completes, execution will return to either the secure
+or non-secure state. The handler routine must return a pointer to
+``cpu_context`` structure of the current CPU for the target security state. On
+AArch64, this return value is currently ignored by the caller as the
+appropriate ``cpu_context`` to be used is expected to be set by the handler
+via the context management library APIs.
+A portable interrupt handler implementation must set the target context both in
+the structure pointed to by the returned pointer and via the context management
+library APIs. The handler should treat all error conditions as critical errors
+and take appropriate action within its implementation e.g. use assertion
+failures.
+
+The runtime firmware provides the following API for registering a handler for a
+particular type of interrupt. A Secure Payload Dispatcher service should use
+this API to register a handler for Secure-EL1 and optionally for non-secure
+interrupts. This API also requires the caller to specify the routing model for
+the type of interrupt.
+
+.. code:: c
+
+    int32_t register_interrupt_type_handler(uint32_t type,
+                                            interrupt_type_handler handler,
+                                            uint64_t flags);
+
+The ``type`` parameter can be one of the three interrupt types listed above i.e.
+``INTR_TYPE_S_EL1``, ``INTR_TYPE_NS`` & ``INTR_TYPE_EL3``. The ``flags`` parameter
+is as described in Section 2.
+
+The function will return ``0`` upon a successful registration. It will return
+``-EALREADY`` in case a handler for the interrupt type has already been
+registered. If the ``type`` is unrecognised or the ``flags`` or the ``handler`` are
+invalid it will return ``-EINVAL``.
+
+Interrupt routing is governed by the configuration of the ``SCR_EL3.FIQ/IRQ`` bits
+prior to entry into a lower exception level in either security state. The
+context management library maintains a copy of the ``SCR_EL3`` system register for
+each security state in the ``cpu_context`` structure of each CPU. It exports the
+following APIs to let EL3 Runtime Firmware program and retrieve the routing
+model for each security state for the current CPU. The value of ``SCR_EL3`` stored
+in the ``cpu_context`` is used by the ``el3_exit()`` function to program the
+``SCR_EL3`` register prior to returning from the EL3 exception level.
+
+.. code:: c
+
+        uint32_t cm_get_scr_el3(uint32_t security_state);
+        void cm_write_scr_el3_bit(uint32_t security_state,
+                                  uint32_t bit_pos,
+                                  uint32_t value);
+
+``cm_get_scr_el3()`` returns the value of the ``SCR_EL3`` register for the specified
+security state of the current CPU. ``cm_write_scr_el3_bit()`` writes a ``0`` or ``1``
+to the bit specified by ``bit_pos``. ``register_interrupt_type_handler()`` invokes
+``set_routing_model()`` API which programs the ``SCR_EL3`` according to the routing
+model using the ``cm_get_scr_el3()`` and ``cm_write_scr_el3_bit()`` APIs.
+
+It is worth noting that in the current implementation of the framework, the EL3
+runtime firmware is responsible for programming the routing model. The SPD is
+responsible for ensuring that the routing model has been adhered to upon
+receiving an interrupt.
+
+.. _spd-int-registration:
+
+Secure payload dispatcher
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+A SPD service is responsible for determining and maintaining the interrupt
+routing model supported by itself and the Secure Payload. It is also responsible
+for ferrying interrupts between secure and non-secure software depending upon
+the routing model. It could determine the routing model at build time or at
+runtime. It must use this information to register a handler for each interrupt
+type using the ``register_interrupt_type_handler()`` API in EL3 runtime firmware.
+
+If the routing model is not known to the SPD service at build time, then it must
+be provided by the SP as the result of its initialisation. The SPD should
+program the routing model only after SP initialisation has completed e.g. in the
+SPD initialisation function pointed to by the ``bl32_init`` variable.
+
+The SPD should determine the mechanism to pass control to the Secure Payload
+after receiving an interrupt from the EL3 runtime firmware. This information
+could either be provided to the SPD service at build time or by the SP at
+runtime.
+
+Test secure payload dispatcher behavior
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+.. note::
+   Where this document discusses ``TSP_NS_INTR_ASYNC_PREEMPT`` as being
+   ``1``, the same results also apply when ``EL3_EXCEPTION_HANDLING`` is ``1``.
+
+The TSPD only handles Secure-EL1 interrupts and is provided with the following
+routing model at build time.
+
+-  Secure-EL1 interrupts are routed to EL3 when execution is in non-secure
+   state and are routed to the FEL when execution is in the secure state
+   i.e **CSS=0, TEL3=0** & **CSS=1, TEL3=1** for Secure-EL1 interrupts
+
+-  When the build flag ``TSP_NS_INTR_ASYNC_PREEMPT`` is zero, the default routing
+   model is used for non-secure interrupts. They are routed to the FEL in
+   either security state i.e **CSS=0, TEL3=0** & **CSS=1, TEL3=0** for
+   Non-secure interrupts.
+
+-  When the build flag ``TSP_NS_INTR_ASYNC_PREEMPT`` is defined to 1, then the
+   non secure interrupts are routed to EL3 when execution is in secure state
+   i.e **CSS=0, TEL3=1** for non-secure interrupts. This effectively preempts
+   Secure-EL1. The default routing model is used for non secure interrupts in
+   non-secure state. i.e **CSS=1, TEL3=0**.
+
+It performs the following actions in the ``tspd_init()`` function to fulfill the
+requirements mentioned earlier.
+
+#. It passes control to the Test Secure Payload to perform its
+   initialisation. The TSP provides the address of the vector table
+   ``tsp_vectors`` in the SP which also includes the handler for Secure-EL1
+   interrupts in the ``sel1_intr_entry`` field. The TSPD passes control to the TSP at
+   this address when it receives a Secure-EL1 interrupt.
+
+   The handover agreement between the TSP and the TSPD requires that the TSPD
+   masks all interrupts (``PSTATE.DAIF`` bits) when it calls
+   ``tsp_sel1_intr_entry()``. The TSP has to preserve the callee saved general
+   purpose, SP_EL1/Secure-EL0, LR, VFP and system registers. It can use
+   ``x0-x18`` to enable its C runtime.
+
+#. The TSPD implements a handler function for Secure-EL1 interrupts. This
+   function is registered with the EL3 runtime firmware using the
+   ``register_interrupt_type_handler()`` API as follows
+
+   .. code:: c
+
+       /* Forward declaration */
+       interrupt_type_handler tspd_secure_el1_interrupt_handler;
+       int32_t rc, flags = 0;
+       set_interrupt_rm_flag(flags, NON_SECURE);
+       rc = register_interrupt_type_handler(INTR_TYPE_S_EL1,

+       if (rc)
+           panic();
+
+#. When the build flag ``TSP_NS_INTR_ASYNC_PREEMPT`` is defined to 1, the TSPD
+   implements a handler function for non-secure interrupts. This function is
+   registered with the EL3 runtime firmware using the
+   ``register_interrupt_type_handler()`` API as follows
+
+   .. code:: c
+
+       /* Forward declaration */
+       interrupt_type_handler tspd_ns_interrupt_handler;
+       int32_t rc, flags = 0;

+
+Secure payload
+~~~~~~~~~~~~~~
+
+A Secure Payload must implement an interrupt handling framework at Secure-EL1
+(Secure-EL1 IHF) to support its chosen interrupt routing model. Secure payload
+execution will alternate between the below cases.
+
+#. In the code where IRQ, FIQ or both interrupts are enabled, if an interrupt
+   type is targeted to the FEL, then it will be routed to the Secure-EL1
+   exception vector table. This is defined as the **asynchronous mode** of
+   handling interrupts. This mode applies to both Secure-EL1 and non-secure
+   interrupts.
+
+#. In the code where both interrupts are disabled, if an interrupt type is
+   targeted to the FEL, then execution will eventually migrate to the
+   non-secure state. Any non-secure interrupts will be handled as described
+   in the routing model where **CSS=1 and TEL3=0**. Secure-EL1 interrupts
+   will be routed to EL3 (as per the routing model where **CSS=1 and
+   TEL3=1**) where the SPD service will hand them to the SP. This is defined
+   as the **synchronous mode** of handling interrupts.
+
+The interrupt handling framework implemented by the SP should support one or
+both these interrupt handling models depending upon the chosen routing model.
+
+The following list briefly describes how the choice of a valid routing model
+(see `Valid routing models`_) effects the implementation of the Secure-EL1
+IHF. If the choice of the interrupt routing model is not known to the SPD
+service at compile time, then the SP should pass this information to the SPD
+service at runtime during its initialisation phase.
+
+As mentioned earlier, an Arm GICv2 system is considered and it is assumed that
+the FIQ signal is used to generate Secure-EL1 interrupts and the IRQ signal
+is used to generate non-secure interrupts in either security state.
+
+Secure payload IHF design w.r.t secure-EL1 interrupts
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+#. **CSS=0, TEL3=0**. If ``PSTATE.F=0``, Secure-EL1 interrupts will be
+   triggered at one of the Secure-EL1 FIQ exception vectors. The Secure-EL1
+   IHF should implement support for handling FIQ interrupts asynchronously.
+
+   If ``PSTATE.F=1`` then Secure-EL1 interrupts will be handled as per the
+   synchronous interrupt handling model. The SP could implement this scenario
+   by exporting a separate entrypoint for Secure-EL1 interrupts to the SPD
+   service during the registration phase. The SPD service would also need to
+   know the state of the system, general purpose and the ``PSTATE`` registers
+   in which it should arrange to return execution to the SP. The SP should
+   provide this information in an implementation defined way during the
+   registration phase if it is not known to the SPD service at build time.
+
+#. **CSS=1, TEL3=1**. Interrupts are routed to EL3 when execution is in
+   non-secure state. They should be handled through the synchronous interrupt
+   handling model as described in 1. above.
+
+#. **CSS=0, TEL3=1**. Secure-EL1 interrupts are routed to EL3 when execution
+   is in secure state. They will not be visible to the SP. The ``PSTATE.F`` bit
+   in Secure-EL1/Secure-EL0 will not mask FIQs. The EL3 runtime firmware will
+   call the handler registered by the SPD service for Secure-EL1 interrupts.
+   Secure-EL1 IHF should then handle all Secure-EL1 interrupt through the
+   synchronous interrupt handling model described in 1. above.
+
+Secure payload IHF design w.r.t non-secure interrupts
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+#. **CSS=0, TEL3=0**. If ``PSTATE.I=0``, non-secure interrupts will be
+   triggered at one of the Secure-EL1 IRQ exception vectors . The Secure-EL1
+   IHF should co-ordinate with the SPD service to transfer execution to the
+   non-secure state where the interrupt should be handled e.g the SP could
+   allocate a function identifier to issue a SMC64 or SMC32 to the SPD
+   service which indicates that the SP execution has been preempted by a
+   non-secure interrupt. If this function identifier is not known to the SPD
+   service at compile time then the SP could provide it during the
+   registration phase.
+
+   If ``PSTATE.I=1`` then the non-secure interrupt will pend until execution
+   resumes in the non-secure state.
+
+#. **CSS=0, TEL3=1**. Non-secure interrupts are routed to EL3. They will not
+   be visible to the SP. The ``PSTATE.I`` bit in Secure-EL1/Secure-EL0 will
+   have not effect. The SPD service should register a non-secure interrupt
+   handler which should save the SP state correctly and resume execution in
+   the non-secure state where the interrupt will be handled. The Secure-EL1
+   IHF does not need to take any action.
+
+#. **CSS=1, TEL3=0**. Non-secure interrupts are handled in the FEL in
+   non-secure state (EL1/EL2) and are not visible to the SP. This routing
+   model does not affect the SP behavior.
+
+A Secure Payload must also ensure that all Secure-EL1 interrupts are correctly
+configured at the interrupt controller by the platform port of the EL3 runtime
+firmware. It should configure any additional Secure-EL1 interrupts which the EL3
+runtime firmware is not aware of through its platform port.
+
+Test secure payload behavior
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The routing model for Secure-EL1 and non-secure interrupts chosen by the TSP is
+described in Section `Secure Payload Dispatcher`__. It is known to the TSPD
+service at build time.
+
+.. __: #spd-int-registration
+
+The TSP implements an entrypoint (``tsp_sel1_intr_entry()``) for handling Secure-EL1
+interrupts taken in non-secure state and routed through the TSPD service
+(synchronous handling model). It passes the reference to this entrypoint via
+``tsp_vectors`` to the TSPD service.
+
+The TSP also replaces the default exception vector table referenced through the
+``early_exceptions`` variable, with a vector table capable of handling FIQ and IRQ
+exceptions taken at the same (Secure-EL1) exception level. This table is
+referenced through the ``tsp_exceptions`` variable and programmed into the
+VBAR_EL1. It caters for the asynchronous handling model.
+
+The TSP also programs the Secure Physical Timer in the Arm Generic Timer block
+to raise a periodic interrupt (every half a second) for the purpose of testing
+interrupt management across all the software components listed in `Software
+components`_.
+
+Interrupt handling
+------------------
+
+This section describes in detail the role of each software component (see
+Section `Software components`_) in handling an interrupt of a particular type.
+
+EL3 runtime firmware
+~~~~~~~~~~~~~~~~~~~~
+
+The EL3 runtime firmware populates the IRQ and FIQ exception vectors referenced
+by the ``runtime_exceptions`` variable as follows.
+
+#. IRQ and FIQ exceptions taken from the current exception level with
+   ``SP_EL0`` or ``SP_EL3`` are reported as irrecoverable error conditions. As
+   mentioned earlier, EL3 runtime firmware always executes with the
+   ``PSTATE.I`` and ``PSTATE.F`` bits set.
+
+#. The following text describes how the IRQ and FIQ exceptions taken from a
+   lower exception level using AArch64 or AArch32 are handled.
+
+When an interrupt is generated, the vector for each interrupt type is
+responsible for:
+
+#. Saving the entire general purpose register context (x0-x30) immediately
+   upon exception entry. The registers are saved in the per-cpu ``cpu_context``
+   data structure referenced by the ``SP_EL3``\ register.
+
+#. Saving the ``ELR_EL3``, ``SP_EL0`` and ``SPSR_EL3`` system registers in the
+   per-cpu ``cpu_context`` data structure referenced by the ``SP_EL3`` register.
+
+#. Switching to the C runtime stack by restoring the ``CTX_RUNTIME_SP`` value
+   from the per-cpu ``cpu_context`` data structure in ``SP_EL0`` and
+   executing the ``msr spsel, #0`` instruction.
+
+#. Determining the type of interrupt. Secure-EL1 interrupts will be signaled
+   at the FIQ vector. Non-secure interrupts will be signaled at the IRQ
+   vector. The platform should implement the following API to determine the
+   type of the pending interrupt.
+
+   .. code:: c
+
+       uint32_t plat_ic_get_interrupt_type(void);
+
+   It should return either ``INTR_TYPE_S_EL1`` or ``INTR_TYPE_NS``.
+
+#. Determining the handler for the type of interrupt that has been generated.
+   The following API has been added for this purpose.
+
+   .. code:: c
+
+       interrupt_type_handler get_interrupt_type_handler(uint32_t interrupt_type);
+
+   It returns the reference to the registered handler for this interrupt
+   type. The ``handler`` is retrieved from the ``intr_type_desc_t`` structure as
+   described in Section 2. ``NULL`` is returned if no handler has been
+   registered for this type of interrupt. This scenario is reported as an
+   irrecoverable error condition.
+
+#. Calling the registered handler function for the interrupt type generated.
+   The ``id`` parameter is set to ``INTR_ID_UNAVAILABLE`` currently. The id along
+   with the current security state and a reference to the ``cpu_context_t``
+   structure for the current security state are passed to the handler function
+   as its arguments.
+
+   The handler function returns a reference to the per-cpu ``cpu_context_t``
+   structure for the target security state.
+
+#. Calling ``el3_exit()`` to return from EL3 into a lower exception level in
+   the security state determined by the handler routine. The ``el3_exit()``
+   function is responsible for restoring the register context from the
+   ``cpu_context_t`` data structure for the target security state.
+
+Secure payload dispatcher
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Interrupt entry
+^^^^^^^^^^^^^^^
+
+The SPD service begins handling an interrupt when the EL3 runtime firmware calls
+the handler function for that type of interrupt. The SPD service is responsible
+for the following:
+
+#. Validating the interrupt. This involves ensuring that the interrupt was
+   generated according to the interrupt routing model specified by the SPD
+   service during registration. It should use the security state of the
+   exception level (passed in the ``flags`` parameter of the handler) where
+   the interrupt was taken from to determine this. If the interrupt is not
+   recognised then the handler should treat it as an irrecoverable error
+   condition.
+
+   An SPD service can register a handler for Secure-EL1 and/or Non-secure
+   interrupts. A non-secure interrupt should never be routed to EL3 from
+   from non-secure state. Also if a routing model is chosen where Secure-EL1
+   interrupts are routed to S-EL1 when execution is in Secure state, then a
+   S-EL1 interrupt should never be routed to EL3 from secure state. The handler
+   could use the security state flag to check this.
+
+#. Determining whether a context switch is required. This depends upon the
+   routing model and interrupt type. For non secure and S-EL1 interrupt,
+   if the security state of the execution context where the interrupt was
+   generated is not the same as the security state required for handling
+   the interrupt, a context switch is required. The following 2 cases
+   require a context switch from secure to non-secure or vice-versa:
+
+   #. A Secure-EL1 interrupt taken from the non-secure state should be
+      routed to the Secure Payload.
+
+   #. A non-secure interrupt taken from the secure state should be routed
+      to the last known non-secure exception level.
+
+   The SPD service must save the system register context of the current
+   security state. It must then restore the system register context of the
+   target security state. It should use the ``cm_set_next_eret_context()`` API
+   to ensure that the next ``cpu_context`` to be restored is of the target
+   security state.
+
+   If the target state is secure then execution should be handed to the SP as
+   per the synchronous interrupt handling model it implements. A Secure-EL1
+   interrupt can be routed to EL3 while execution is in the SP. This implies
+   that SP execution can be preempted while handling an interrupt by a
+   another higher priority Secure-EL1 interrupt or a EL3 interrupt. The SPD
+   service should be able to handle this preemption or manage secure interrupt
+   priorities before handing control to the SP.
+
+#. Setting the return value of the handler to the per-cpu ``cpu_context`` if
+   the interrupt has been successfully validated and ready to be handled at a
+   lower exception level.
+
+The routing model allows non-secure interrupts to interrupt Secure-EL1 when in
+secure state if it has been configured to do so. The SPD service and the SP
+should implement a mechanism for routing these interrupts to the last known
+exception level in the non-secure state. The former should save the SP context,
+restore the non-secure context and arrange for entry into the non-secure state
+so that the interrupt can be handled.
+
+Interrupt exit
+^^^^^^^^^^^^^^
+
+When the Secure Payload has finished handling a Secure-EL1 interrupt, it could
+return control back to the SPD service through a SMC32 or SMC64. The SPD service
+should handle this secure monitor call so that execution resumes in the
+exception level and the security state from where the Secure-EL1 interrupt was
+originally taken.
+
+Test secure payload dispatcher Secure-EL1 interrupt handling
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The example TSPD service registers a handler for Secure-EL1 interrupts taken
+from the non-secure state. During execution in S-EL1, the TSPD expects that the
+Secure-EL1 interrupts are handled in S-EL1 by TSP. Its handler
+``tspd_secure_el1_interrupt_handler()`` expects only to be invoked for Secure-EL1
+originating from the non-secure state. It takes the following actions upon being
+invoked.
+
+#. It uses the security state provided in the ``flags`` parameter to ensure
+   that the secure interrupt originated from the non-secure state. It asserts
+   if this is not the case.
+
+#. It saves the system register context for the non-secure state by calling
+   ``cm_el1_sysregs_context_save(NON_SECURE);``.
+
+#. It sets the ``ELR_EL3`` system register to ``tsp_sel1_intr_entry`` and sets the
+   ``SPSR_EL3.DAIF`` bits in the secure CPU context. It sets ``x0`` to
+   ``TSP_HANDLE_SEL1_INTR_AND_RETURN``. If the TSP was preempted earlier by a non
+   secure interrupt during ``yielding`` SMC processing, save the registers that
+   will be trashed, which is the ``ELR_EL3`` and ``SPSR_EL3``, in order to be able
+   to re-enter TSP for Secure-EL1 interrupt processing. It does not need to
+   save any other secure context since the TSP is expected to preserve it
+   (see section `Test secure payload dispatcher behavior`_).
+
+#. It restores the system register context for the secure state by calling
+   ``cm_el1_sysregs_context_restore(SECURE);``.
+
+#. It ensures that the secure CPU context is used to program the next
+   exception return from EL3 by calling ``cm_set_next_eret_context(SECURE);``.
+
+#. It returns the per-cpu ``cpu_context`` to indicate that the interrupt can
+   now be handled by the SP. ``x1`` is written with the value of ``elr_el3``
+   register for the non-secure state. This information is used by the SP for
+   debugging purposes.
+
+The figure below describes how the interrupt handling is implemented by the TSPD
+when a Secure-EL1 interrupt is generated when execution is in the non-secure
+state.
+
+|Image 1|
+
+The TSP issues an SMC with ``TSP_HANDLED_S_EL1_INTR`` as the function identifier to
+signal completion of interrupt handling.
+
+The TSPD service takes the following actions in ``tspd_smc_handler()`` function
+upon receiving an SMC with ``TSP_HANDLED_S_EL1_INTR`` as the function identifier:
+
+#. It ensures that the call originated from the secure state otherwise
+   execution returns to the non-secure state with ``SMC_UNK`` in ``x0``.
+
+#. It restores the saved ``ELR_EL3`` and ``SPSR_EL3`` system registers back to
+   the secure CPU context (see step 3 above) in case the TSP had been preempted
+   by a non secure interrupt earlier.
+
+#. It restores the system register context for the non-secure state by
+   calling ``cm_el1_sysregs_context_restore(NON_SECURE)``.
+
+#. It ensures that the non-secure CPU context is used to program the next
+   exception return from EL3 by calling ``cm_set_next_eret_context(NON_SECURE)``.
+
+#. ``tspd_smc_handler()`` returns a reference to the non-secure ``cpu_context``
+   as the return value.
+
+Test secure payload dispatcher non-secure interrupt handling
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The TSP in Secure-EL1 can be preempted by a non-secure interrupt during
+``yielding`` SMC processing or by a higher priority EL3 interrupt during
+Secure-EL1 interrupt processing. When ``EL3_EXCEPTION_HANDLING`` is ``0``, only
+non-secure interrupts can cause preemption of TSP since there are no EL3
+interrupts in the system. With ``EL3_EXCEPTION_HANDLING=1`` however, any EL3
+interrupt may preempt Secure execution.
+
+It should be noted that while TSP is preempted, the TSPD only allows entry into
+the TSP either for Secure-EL1 interrupt handling or for resuming the preempted
+``yielding`` SMC in response to the ``TSP_FID_RESUME`` SMC from the normal world.
+(See Section `Implication of preempted SMC on Non-Secure Software`_).
+
+The non-secure interrupt triggered in Secure-EL1 during ``yielding`` SMC
+processing can be routed to either EL3 or Secure-EL1 and is controlled by build
+option ``TSP_NS_INTR_ASYNC_PREEMPT`` (see Section `Test secure payload
+dispatcher behavior`_). If the build option is set, the TSPD will set the
+routing model for the non-secure interrupt to be routed to EL3 from secure state
+i.e. **TEL3=1, CSS=0** and registers ``tspd_ns_interrupt_handler()`` as the
+non-secure interrupt handler. The ``tspd_ns_interrupt_handler()`` on being
+invoked ensures that the interrupt originated from the secure state and disables
+routing of non-secure interrupts from secure state to EL3. This is to prevent
+further preemption (by a non-secure interrupt) when TSP is reentered for
+handling Secure-EL1 interrupts that triggered while execution was in the normal
+world. The ``tspd_ns_interrupt_handler()`` then invokes
+``tspd_handle_sp_preemption()`` for further handling.
+
+If the ``TSP_NS_INTR_ASYNC_PREEMPT`` build option is zero (default), the default
+routing model for non-secure interrupt in secure state is in effect
+i.e. **TEL3=0, CSS=0**. During ``yielding`` SMC processing, the IRQ
+exceptions are unmasked i.e. ``PSTATE.I=0``, and a non-secure interrupt will
+trigger at Secure-EL1 IRQ exception vector. The TSP saves the general purpose
+register context and issues an SMC with ``TSP_PREEMPTED`` as the function
+identifier to signal preemption of TSP. The TSPD SMC handler,
+``tspd_smc_handler()``, ensures that the SMC call originated from the
+secure state otherwise execution returns to the non-secure state with
+``SMC_UNK`` in ``x0``. It then invokes ``tspd_handle_sp_preemption()`` for
+further handling.
+
+The ``tspd_handle_sp_preemption()`` takes the following actions upon being
+invoked:
+
+#. It saves the system register context for the secure state by calling
+   ``cm_el1_sysregs_context_save(SECURE)``.
+
+#. It restores the system register context for the non-secure state by
+   calling ``cm_el1_sysregs_context_restore(NON_SECURE)``.
+
+#. It ensures that the non-secure CPU context is used to program the next
+   exception return from EL3 by calling ``cm_set_next_eret_context(NON_SECURE)``.
+
+#. ``SMC_PREEMPTED`` is set in x0 and return to non secure state after
+   restoring non secure context.
+
+The Normal World is expected to resume the TSP after the ``yielding`` SMC
+preemption by issuing an SMC with ``TSP_FID_RESUME`` as the function identifier
+(see section `Implication of preempted SMC on Non-Secure Software`_).  The TSPD
+service takes the following actions in ``tspd_smc_handler()`` function upon
+receiving this SMC:
+
+#. It ensures that the call originated from the non secure state. An
+   assertion is raised otherwise.
+
+#. Checks whether the TSP needs a resume i.e check if it was preempted. It
+   then saves the system register context for the non-secure state by calling
+   ``cm_el1_sysregs_context_save(NON_SECURE)``.
+
+#. Restores the secure context by calling
+   ``cm_el1_sysregs_context_restore(SECURE)``
+
+#. It ensures that the secure CPU context is used to program the next
+   exception return from EL3 by calling ``cm_set_next_eret_context(SECURE)``.
+
+#. ``tspd_smc_handler()`` returns a reference to the secure ``cpu_context`` as the
+   return value.
+
+The figure below describes how the TSP/TSPD handle a non-secure interrupt when
+it is generated during execution in the TSP with ``PSTATE.I`` = 0 when the
+``TSP_NS_INTR_ASYNC_PREEMPT`` build flag is 0.
+

+
+.. _sp-synchronous-int:
+
+Secure payload interrupt handling
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The SP should implement one or both of the synchronous and asynchronous
+interrupt handling models depending upon the interrupt routing model it has
+chosen (as described in section :ref:`Secure Payload <sp-int-registration>`).
+
+In the synchronous model, it should begin handling a Secure-EL1 interrupt after
+receiving control from the SPD service at an entrypoint agreed upon during build
+time or during the registration phase. Before handling the interrupt, the SP
+should save any Secure-EL1 system register context which is needed for resuming
+normal execution in the SP later e.g. ``SPSR_EL1``, ``ELR_EL1``. After handling
+the interrupt, the SP could return control back to the exception level and
+security state where the interrupt was originally taken from. The SP should use
+an SMC32 or SMC64 to ask the SPD service to do this.
+
+In the asynchronous model, the Secure Payload is responsible for handling
+non-secure and Secure-EL1 interrupts at the IRQ and FIQ vectors in its exception
+vector table when ``PSTATE.I`` and ``PSTATE.F`` bits are 0. As described earlier,
+when a non-secure interrupt is generated, the SP should coordinate with the SPD
+service to pass control back to the non-secure state in the last known exception
+level. This will allow the non-secure interrupt to be handled in the non-secure
+state.
+
+Test secure payload behavior
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The TSPD hands control of a Secure-EL1 interrupt to the TSP at the
+``tsp_sel1_intr_entry()``. The TSP handles the interrupt while ensuring that the
+handover agreement described in Section `Test secure payload dispatcher
+behavior`_ is maintained. It updates some statistics by calling
+``tsp_update_sync_sel1_intr_stats()``. It then calls
+``tsp_common_int_handler()`` which.
+
+#. Checks whether the interrupt is the secure physical timer interrupt. It
+   uses the platform API ``plat_ic_get_pending_interrupt_id()`` to get the
+   interrupt number. If it is not the secure physical timer interrupt, then
+   that means that a higher priority interrupt has preempted it. Invoke
+   ``tsp_handle_preemption()`` to handover control back to EL3 by issuing
+   an SMC with ``TSP_PREEMPTED`` as the function identifier.
+
+#. Handles the secure timer interrupt interrupt by acknowledging it using the
+   ``plat_ic_acknowledge_interrupt()`` platform API, calling
+   ``tsp_generic_timer_handler()`` to reprogram the secure physical generic
+   timer and calling the ``plat_ic_end_of_interrupt()`` platform API to signal
+   end of interrupt processing.
+
+The TSP passes control back to the TSPD by issuing an SMC64 with
+``TSP_HANDLED_S_EL1_INTR`` as the function identifier.
+
+The TSP handles interrupts under the asynchronous model as follows.
+
+#. Secure-EL1 interrupts are handled by calling the ``tsp_common_int_handler()``
+   function. The function has been described above.
+
+#. Non-secure interrupts are handled by calling the ``tsp_common_int_handler()``
+   function which ends up invoking ``tsp_handle_preemption()`` and issuing an
+   SMC64 with ``TSP_PREEMPTED`` as the function identifier. Execution resumes at
+   the instruction that follows this SMC instruction when the TSPD hands control
+   to the TSP in response to an SMC with ``TSP_FID_RESUME`` as the function
+   identifier from the non-secure state (see section `Test secure payload
+   dispatcher non-secure interrupt handling`_).
+
+Other considerations
+--------------------
+
+Implication of preempted SMC on Non-Secure Software
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+A ``yielding`` SMC call to Secure payload can be preempted by a non-secure
+interrupt and the execution can return to the non-secure world for handling
+the interrupt (For details on ``yielding`` SMC refer `SMC calling convention`_).
+In this case, the SMC call has not completed its execution and the execution
+must return back to the secure payload to resume the preempted SMC call.
+This can be achieved by issuing an SMC call which instructs to resume the
+preempted SMC.
+
+A ``fast`` SMC cannot be preempted and hence this case will not happen for
+a fast SMC call.
+
+In the Test Secure Payload implementation, ``TSP_FID_RESUME`` is designated
+as the resume SMC FID. It is important to note that ``TSP_FID_RESUME`` is a
+``yielding`` SMC which means it too can be be preempted. The typical non
+secure software sequence for issuing a ``yielding`` SMC would look like this,
+assuming ``P.STATE.I=0`` in the non secure state :
+

+        rc = smc(TSP_FID_RESUME);       /* Issue resume SMC call */
+    }
+
+The ``TSP_YIELD_SMC_FID`` is any ``yielding`` SMC function identifier and the smc()
+function invokes a SMC call with the required arguments. The pending non-secure
+interrupt causes an IRQ exception and the IRQ handler registered at the
+exception vector handles the non-secure interrupt and returns. The return value
+from the SMC call is tested for ``SMC_PREEMPTED`` to check whether it is
+preempted. If it is, then the resume SMC call ``TSP_FID_RESUME`` is issued. The
+return value of the SMC call is tested again to check if it is preempted.
+This is done in a loop till the SMC call succeeds or fails. If a ``yielding``
+SMC is preempted, until it is resumed using ``TSP_FID_RESUME`` SMC and
+completed, the current TSPD prevents any other SMC call from re-entering
+TSP by returning ``SMC_UNK`` error.

+PSCI Power Domain Tree Structure
+================================
+
+Requirements
+------------
+
+#. A platform must export the ``plat_get_aff_count()`` and
+   ``plat_get_aff_state()`` APIs to enable the generic PSCI code to
+   populate a tree that describes the hierarchy of power domains in the
+   system. This approach is inflexible because a change to the topology
+   requires a change in the code.
+
+   It would be much simpler for the platform to describe its power domain tree
+   in a data structure.
+
+#. The generic PSCI code generates MPIDRs in order to populate the power domain
+   tree. It also uses an MPIDR to find a node in the tree. The assumption that
+   a platform will use exactly the same MPIDRs as generated by the generic PSCI
+   code is not scalable. The use of an MPIDR also restricts the number of
+   levels in the power domain tree to four.
+
+   Therefore, there is a need to decouple allocation of MPIDRs from the
+   mechanism used to populate the power domain topology tree.
+
+#. The current arrangement of the power domain tree requires a binary search
+   over the sibling nodes at a particular level to find a specified power
+   domain node. During a power management operation, the tree is traversed from
+   a 'start' to an 'end' power level. The binary search is required to find the
+   node at each level. The natural way to perform this traversal is to
+   start from a leaf node and follow the parent node pointer to reach the end
+   level.
+
+   Therefore, there is a need to define data structures that implement the tree in
+   a way which facilitates such a traversal.
+
+#. The attributes of a core power domain differ from the attributes of power
+   domains at higher levels. For example, only a core power domain can be identified
+   using an MPIDR. There is no requirement to perform state coordination while
+   performing a power management operation on the core power domain.
+
+   Therefore, there is a need to implement the tree in a way which facilitates this
+   distinction between a leaf and non-leaf node and any associated
+   optimizations.
+
+--------------
+
+Design
+------
+
+Describing a power domain tree
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+To fulfill requirement 1., the existing platform APIs
+``plat_get_aff_count()`` and ``plat_get_aff_state()`` have been
+removed. A platform must define an array of unsigned chars such that:
+
+#. The first entry in the array specifies the number of power domains at the
+   highest power level implemented in the platform. This caters for platforms
+   where the power domain tree does not have a single root node, for example,
+   the FVP has two cluster power domains at the highest level (1).
+
+#. Each subsequent entry corresponds to a power domain and contains the number
+   of power domains that are its direct children.
+
+#. The size of the array minus the first entry will be equal to the number of
+   non-leaf power domains.
+
+#. The value in each entry in the array is used to find the number of entries
+   to consider at the next level. The sum of the values (number of children) of
+   all the entries at a level specifies the number of entries in the array for
+   the next level.
+
+The following example power domain topology tree will be used to describe the
+above text further. The leaf and non-leaf nodes in this tree have been numbered
+separately.
+
+::
+
+                                         +-+

+
+This tree is defined by the platform as the array described above as follows:
+
+.. code:: c
+
+        #define PLAT_NUM_POWER_DOMAINS       20
+        #define PLATFORM_CORE_COUNT          13
+        #define PSCI_NUM_NON_CPU_PWR_DOMAINS \
+                           (PLAT_NUM_POWER_DOMAINS - PLATFORM_CORE_COUNT)
+
+        unsigned char plat_power_domain_tree_desc[] = { 1, 2, 2, 2, 3, 3, 3, 4};
+
+Removing assumptions about MPIDRs used in a platform
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+To fulfill requirement 2., it is assumed that the platform assigns a
+unique number (core index) between ``0`` and ``PLAT_CORE_COUNT - 1`` to each core
+power domain. MPIDRs could be allocated in any manner and will not be used to
+populate the tree.
+
+``plat_core_pos_by_mpidr(mpidr)`` will return the core index for the core
+corresponding to the MPIDR. It will return an error (-1) if an MPIDR is passed
+which is not allocated or corresponds to an absent core. The semantics of this
+platform API have changed since it is required to validate the passed MPIDR. It
+has been made a mandatory API as a result.
+
+Another mandatory API, ``plat_my_core_pos()`` has been added to return the core
+index for the calling core. This API provides a more lightweight mechanism to get
+the index since there is no need to validate the MPIDR of the calling core.
+
+The platform should assign the core indices (as illustrated in the diagram above)
+such that, if the core nodes are numbered from left to right, then the index
+for a core domain will be the same as the index returned by
+``plat_core_pos_by_mpidr()`` or ``plat_my_core_pos()`` for that core. This
+relationship allows the core nodes to be allocated in a separate array
+(requirement 4.) during ``psci_setup()`` in such an order that the index of the
+core in the array is the same as the return value from these APIs.
+
+Dealing with holes in MPIDR allocation
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+For platforms where the number of allocated MPIDRs is equal to the number of
+core power domains, for example, Juno and FVPs, the logic to convert an MPIDR to
+a core index should remain unchanged. Both Juno and FVP use a simple collision
+proof hash function to do this.
+
+It is possible that on some platforms, the allocation of MPIDRs is not
+contiguous or certain cores have been disabled. This essentially means that the
+MPIDRs have been sparsely allocated, that is, the size of the range of MPIDRs
+used by the platform is not equal to the number of core power domains.
+
+The platform could adopt one of the following approaches to deal with this
+scenario:
+
+#. Implement more complex logic to convert a valid MPIDR to a core index while
+   maintaining the relationship described earlier. This means that the power
+   domain tree descriptor will not describe any core power domains which are
+   disabled or absent. Entries will not be allocated in the tree for these
+   domains.
+
+#. Treat unallocated MPIDRs and disabled cores as absent but still describe them
+   in the power domain descriptor, that is, the number of core nodes described
+   is equal to the size of the range of MPIDRs allocated. This approach will
+   lead to memory wastage since entries will be allocated in the tree but will
+   allow use of a simpler logic to convert an MPIDR to a core index.
+
+Traversing through and distinguishing between core and non-core power domains
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+To fulfill requirement 3 and 4, separate data structures have been defined
+to represent leaf and non-leaf power domain nodes in the tree.
+
+.. code:: c
+
+    /*******************************************************************************
+     * The following two data structures implement the power domain tree. The tree
+     * is used to track the state of all the nodes i.e. power domain instances
+     * described by the platform. The tree consists of nodes that describe CPU power
+     * domains i.e. leaf nodes and all other power domains which are parents of a
+     * CPU power domain i.e. non-leaf nodes.
+     ******************************************************************************/
+    typedef struct non_cpu_pwr_domain_node {
+        /*
+         * Index of the first CPU power domain node level 0 which has this node
+         * as its parent.
+         */
+        unsigned int cpu_start_idx;
+
+        /*
+         * Number of CPU power domains which are siblings of the domain indexed
+         * by 'cpu_start_idx' i.e. all the domains in the range 'cpu_start_idx
+         * -> cpu_start_idx + ncpus' have this node as their parent.
+         */
+        unsigned int ncpus;
+
+        /* Index of the parent power domain node */
+        unsigned int parent_node;
+
+        -----
+    } non_cpu_pd_node_t;
+
+    typedef struct cpu_pwr_domain_node {
+        u_register_t mpidr;
+
+        /* Index of the parent power domain node */
+        unsigned int parent_node;
+
+        -----
+    } cpu_pd_node_t;
+
+The power domain tree is implemented as a combination of the following data
+structures.
+
+.. code:: c
+
+    non_cpu_pd_node_t psci_non_cpu_pd_nodes[PSCI_NUM_NON_CPU_PWR_DOMAINS];
+    cpu_pd_node_t psci_cpu_pd_nodes[PLATFORM_CORE_COUNT];
+
+Populating the power domain tree
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The ``populate_power_domain_tree()`` function in ``psci_setup.c`` implements the
+algorithm to parse the power domain descriptor exported by the platform to
+populate the two arrays. It is essentially a breadth-first-search. The nodes for
+each level starting from the root are laid out one after another in the
+``psci_non_cpu_pd_nodes`` and ``psci_cpu_pd_nodes`` arrays as follows:
+
+::
+
+    psci_non_cpu_pd_nodes -> [[Level 3 nodes][Level 2 nodes][Level 1 nodes]]
+    psci_cpu_pd_nodes -> [Level 0 nodes]
+
+For the example power domain tree illustrated above, the ``psci_cpu_pd_nodes``
+will be populated as follows. The value in each entry is the index of the parent
+node. Other fields have been ignored for simplicity.
+
+::

+CPU Reset
+=========
+
+This document describes the high-level design of the framework to handle CPU
+resets in Trusted Firmware-A (TF-A). It also describes how the platform
+integrator can tailor this code to the system configuration to some extent,
+resulting in a simplified and more optimised boot flow.
+
+This document should be used in conjunction with the :ref:`Firmware Design`
+document which provides greater implementation details around the reset code,
+specifically for the cold boot path.
+
+General reset code flow
+-----------------------
+
+The TF-A reset code is implemented in BL1 by default. The following high-level
+diagram illustrates this:
+
+|Default reset code flow|
+
+This diagram shows the default, unoptimised reset flow. Depending on the system
+configuration, some of these steps might be unnecessary. The following sections
+guide the platform integrator by indicating which build options exclude which
+steps, depending on the capability of the platform.
+
+.. note::
+   If BL31 is used as the TF-A entry point instead of BL1, the diagram
+   above is still relevant, as all these operations will occur in BL31 in
+   this case. Please refer to section 6 "Using BL31 entrypoint as the reset
+   address" for more information.
+
+Programmable CPU reset address
+------------------------------
+
+By default, TF-A assumes that the CPU reset address is not programmable.
+Therefore, all CPUs start at the same address (typically address 0) whenever
+they reset. Further logic is then required to identify whether it is a cold or
+warm boot to direct CPUs to the right execution path.
+
+If the reset vector address (reflected in the reset vector base address register
+``RVBAR_EL3``) is programmable then it is possible to make each CPU start directly
+at the right address, both on a cold and warm reset. Therefore, the boot type
+detection can be skipped, resulting in the following boot flow:
+
+|Reset code flow with programmable reset address|
+
+To enable this boot flow, compile TF-A with ``PROGRAMMABLE_RESET_ADDRESS=1``.
+This option only affects the TF-A reset image, which is BL1 by default or BL31 if
+``RESET_TO_BL31=1``.
+
+On both the FVP and Juno platforms, the reset vector address is not programmable
+so both ports use ``PROGRAMMABLE_RESET_ADDRESS=0``.
+
+Cold boot on a single CPU
+-------------------------
+
+By default, TF-A assumes that several CPUs may be released out of reset.
+Therefore, the cold boot code has to arbitrate access to hardware resources
+shared amongst CPUs. This is done by nominating one of the CPUs as the primary,
+which is responsible for initialising shared hardware and coordinating the boot
+flow with the other CPUs.
+
+If the platform guarantees that only a single CPU will ever be brought up then
+no arbitration is required. The notion of primary/secondary CPU itself no longer
+applies. This results in the following boot flow:
+
+|Reset code flow with single CPU released out of reset|
+
+To enable this boot flow, compile TF-A with ``COLD_BOOT_SINGLE_CPU=1``. This
+option only affects the TF-A reset image, which is BL1 by default or BL31 if
+``RESET_TO_BL31=1``.
+
+On both the FVP and Juno platforms, although only one core is powered up by
+default, there are platform-specific ways to release any number of cores out of
+reset. Therefore, both platform ports use ``COLD_BOOT_SINGLE_CPU=0``.

+It is obviously possible to combine both optimisations on platforms that have
+a programmable CPU reset address and which release a single CPU out of reset.
+This results in the following boot flow:
+
+
+|Reset code flow with programmable reset address and single CPU released out of reset|
+
+To enable this boot flow, compile TF-A with both ``COLD_BOOT_SINGLE_CPU=1``
+and ``PROGRAMMABLE_RESET_ADDRESS=1``. These options only affect the TF-A reset
+image, which is BL1 by default or BL31 if ``RESET_TO_BL31=1``.
+
+Using BL31 entrypoint as the reset address
+------------------------------------------
+
+On some platforms the runtime firmware (BL3x images) for the application
+processors are loaded by some firmware running on a secure system processor
+on the SoC, rather than by BL1 and BL2 running on the primary application
+processor. For this type of SoC it is desirable for the application processor
+to always reset to BL31 which eliminates the need for BL1 and BL2.
+
+TF-A provides a build-time option ``RESET_TO_BL31`` that includes some additional
+logic in the BL31 entry point to support this use case.
+
+In this configuration, the platform's Trusted Boot Firmware must ensure that
+BL31 is loaded to its runtime address, which must match the CPU's ``RVBAR_EL3``
+reset vector base address, before the application processor is powered on.
+Additionally, platform software is responsible for loading the other BL3x images
+required and providing entry point information for them to BL31. Loading these
+images might be done by the Trusted Boot Firmware or by platform code in BL31.
+
+Although the Arm FVP platform does not support programming the reset base
+address dynamically at run-time, it is possible to set the initial value of the
+``RVBAR_EL3`` register at start-up. This feature is provided on the Base FVP
+only.
+
+It allows the Arm FVP port to support the ``RESET_TO_BL31`` configuration, in
+which case the ``bl31.bin`` image must be loaded to its run address in Trusted
+SRAM and all CPU reset vectors be changed from the default ``0x0`` to this run
+address. See the :ref:`Arm Fixed Virtual Platforms (FVP)` for details of running
+the FVP models in this way.
+
+Although technically it would be possible to program the reset base address with
+the right support in the SCP firmware, this is currently not implemented so the
+Juno port doesn't support the ``RESET_TO_BL31`` configuration.
+
+The ``RESET_TO_BL31`` configuration requires some additions and changes in the
+BL31 functionality:
+
+Determination of boot path
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+In this configuration, BL31 uses the same reset framework and code as the one
+described for BL1 above. Therefore, it is affected by the
+``PROGRAMMABLE_RESET_ADDRESS`` and ``COLD_BOOT_SINGLE_CPU`` build options in the
+same way.
+
+In the default, unoptimised BL31 reset flow, on a warm boot a CPU is directed
+to the PSCI implementation via a platform defined mechanism. On a cold boot,
+the platform must place any secondary CPUs into a safe state while the primary
+CPU executes a modified BL31 initialization, as described below.
+
+Platform initialization
+~~~~~~~~~~~~~~~~~~~~~~~
+
+In this configuration, when the CPU resets to BL31 there should be no parameters
+that can be passed in registers by previous boot stages. Instead, the platform
+code in BL31 needs to know, or be able to determine, the location of the BL32
+(if required) and BL33 images and provide this information in response to the
+``bl31_plat_get_next_image_ep_info()`` function.
+
+.. note::
+   Some platforms that configure ``RESET_TO_BL31`` might still be able to
+   receive parameters in registers depending on their actual boot sequence. On
+   those occasions, and in addition to ``RESET_TO_BL31``, these platforms should
+   set ``RESET_TO_BL31_WITH_PARAMS`` to avoid the input registers from being
+   zeroed before entering BL31.
+
+Additionally, platform software is responsible for carrying out any security
+initialisation, for example programming a TrustZone address space controller.
+This might be done by the Trusted Boot Firmware or by platform code in BL31.

+Building FIP images with support for Trusted Board Boot
+=======================================================
+
+Trusted Board Boot primarily consists of the following two features:
+
+-  Image Authentication, described in :ref:`Trusted Board Boot`, and
+-  Firmware Update, described in :ref:`Firmware Update (FWU)`
+
+The following steps should be followed to build FIP and (optionally) FWU_FIP
+images with support for these features:
+
+#. Fulfill the dependencies of the ``mbedtls`` cryptographic and image parser
+   modules by checking out a recent version of the `mbed TLS Repository`_. It
+   is important to use a version that is compatible with TF-A and fixes any
+   known security vulnerabilities. See `mbed TLS Security Center`_ for more
+   information. See the :ref:`Prerequisites` document for the appropriate
+   version of mbed TLS to use.
+
+   The ``drivers/auth/mbedtls/mbedtls_*.mk`` files contain the list of mbed TLS
+   source files the modules depend upon.
+   ``include/drivers/auth/mbedtls/mbedtls_config.h`` contains the configuration
+   options required to build the mbed TLS sources.
+
+   Note that the mbed TLS library is licensed under the Apache version 2.0
+   license. Using mbed TLS source code will affect the licensing of TF-A
+   binaries that are built using this library.
+
+#. To build the FIP image, ensure the following command line variables are set
+   while invoking ``make`` to build TF-A:
+
+   -  ``MBEDTLS_DIR=<path of the directory containing mbed TLS sources>``
+   -  ``TRUSTED_BOARD_BOOT=1``
+   -  ``GENERATE_COT=1``
+
+   By default, this will use the Chain of Trust described in the TBBR-client
+   document. To select a different one, use the ``COT`` build option.
+
+   If using a custom build of OpenSSL, set the ``OPENSSL_DIR`` variable
+   accordingly so it points at the OpenSSL installation path, as explained in
+   :ref:`Build Options`. In addition, set the ``LD_LIBRARY_PATH`` variable
+   when running to point at the custom OpenSSL path, so the OpenSSL libraries
+   are loaded from that path instead of the default OS path. Export this
+   variable if necessary.
+
+   In the case of Arm platforms, the location of the ROTPK hash must also be
+   specified at build time. The following locations are currently supported (see
+   ``ARM_ROTPK_LOCATION`` build option):
+
+   -  ``ARM_ROTPK_LOCATION=regs``: the ROTPK hash is obtained from the Trusted
+      root-key storage registers present in the platform. On Juno, these
+      registers are read-only. On FVP Base and Cortex models, the registers
+      are also read-only, but the value can be specified using the command line
+      option ``bp.trusted_key_storage.public_key`` when launching the model.
+      On Juno board, the default value corresponds to an ECDSA-SECP256R1 public
+      key hash, whose private part is not currently available.
+
+   -  ``ARM_ROTPK_LOCATION=devel_rsa``: use the default hash located in
+      ``plat/arm/board/common/rotpk/arm_rotpk_rsa_sha256.bin``. Enforce
+      generation of the new hash if ``ROT_KEY`` is specified.
+
+   -  ``ARM_ROTPK_LOCATION=devel_ecdsa``: use the default hash located in
+      ``plat/arm/board/common/rotpk/arm_rotpk_ecdsa_sha256.bin``. Enforce
+      generation of the new hash if ``ROT_KEY`` is specified.
+
+   Example of command line using RSA development keys:
+
+   .. code:: shell
+
+       MBEDTLS_DIR=<path of the directory containing mbed TLS sources> \
+       make PLAT=<platform> TRUSTED_BOARD_BOOT=1 GENERATE_COT=1        \
+       ARM_ROTPK_LOCATION=devel_rsa                                    \
+       ROT_KEY=plat/arm/board/common/rotpk/arm_rotprivk_rsa.pem        \
+       BL33=<path-to>/<bl33_image> OPENSSL_DIR=<path-to>/<openssl>     \
+       all fip
+
+   The result of this build will be the bl1.bin and the fip.bin binaries. This
+   FIP will include the certificates corresponding to the selected Chain of
+   Trust. These certificates can also be found in the output build directory.
+
+#. The optional FWU_FIP contains any additional images to be loaded from
+   Non-Volatile storage during the :ref:`Firmware Update (FWU)` process. To build the
+   FWU_FIP, any FWU images required by the platform must be specified on the
+   command line. On Arm development platforms like Juno, these are:
+
+   -  NS_BL2U. The AP non-secure Firmware Updater image.
+   -  SCP_BL2U. The SCP Firmware Update Configuration image.
+
+   Example of Juno command line for generating both ``fwu`` and ``fwu_fip``
+   targets using RSA development:
+
+   ::
+
+       MBEDTLS_DIR=<path of the directory containing mbed TLS sources> \
+       make PLAT=juno TRUSTED_BOARD_BOOT=1 GENERATE_COT=1              \
+       ARM_ROTPK_LOCATION=devel_rsa                                    \
+       ROT_KEY=plat/arm/board/common/rotpk/arm_rotprivk_rsa.pem        \
+       BL33=<path-to>/<bl33_image> OPENSSL_DIR=<path-to>/<openssl>     \
+       SCP_BL2=<path-to>/<scp_bl2_image>                               \
+       SCP_BL2U=<path-to>/<scp_bl2u_image>                             \
+       NS_BL2U=<path-to>/<ns_bl2u_image>                               \
+       all fip fwu_fip
+
+   .. note::
+      The BL2U image will be built by default and added to the FWU_FIP.
+      The user may override this by adding ``BL2U=<path-to>/<bl2u_image>``
+      to the command line above.
+
+   .. note::
+      Building and installing the non-secure and SCP FWU images (NS_BL1U,
+      NS_BL2U and SCP_BL2U) is outside the scope of this document.
+
+   The result of this build will be bl1.bin, fip.bin and fwu_fip.bin binaries.
+   Both the FIP and FWU_FIP will include the certificates corresponding to the
+   selected Chain of Trust. These certificates can also be found in the output
+   build directory.

+Trusted Board Boot
+==================
+
+The Trusted Board Boot (TBB) feature prevents malicious firmware from running on
+the platform by authenticating all firmware images up to and including the
+normal world bootloader. It does this by establishing a Chain of Trust using
+Public-Key-Cryptography Standards (PKCS).
+
+This document describes the design of Trusted Firmware-A (TF-A) TBB, which is an
+implementation of the `Trusted Board Boot Requirements (TBBR)`_ specification,
+Arm DEN0006D. It should be used in conjunction with the
+:ref:`Firmware Update (FWU)` design document, which implements a specific aspect
+of the TBBR.
+
+Chain of Trust
+--------------
+
+A Chain of Trust (CoT) starts with a set of implicitly trusted components. On
+the Arm development platforms, these components are:
+
+-  A SHA-256 hash of the Root of Trust Public Key (ROTPK). It is stored in the
+   trusted root-key storage registers. Alternatively, a development ROTPK might
+   be used and its hash embedded into the BL1 and BL2 images (only for
+   development purposes).
+
+-  The BL1 image, on the assumption that it resides in ROM so cannot be
+   tampered with.
+
+The remaining components in the CoT are either certificates or boot loader
+images. The certificates follow the `X.509 v3`_ standard. This standard
+enables adding custom extensions to the certificates, which are used to store
+essential information to establish the CoT.
+
+In the TBB CoT all certificates are self-signed. There is no need for a
+Certificate Authority (CA) because the CoT is not established by verifying the
+validity of a certificate's issuer but by the content of the certificate
+extensions. To sign the certificates, different signature schemes are available,
+please refer to the :ref:`Build Options` for more details.
+
+The certificates are categorised as "Key" and "Content" certificates. Key
+certificates are used to verify public keys which have been used to sign content
+certificates. Content certificates are used to store the hash of a boot loader
+image. An image can be authenticated by calculating its hash and matching it
+with the hash extracted from the content certificate. Various hash algorithms
+are supported to calculate all hashes, please refer to the :ref:`Build Options`
+for more details.. The public keys and hashes are included as non-standard
+extension fields in the `X.509 v3`_ certificates.
+
+The keys used to establish the CoT are:
+
+-  **Root of trust key**
+
+   The private part of this key is used to sign the BL2 content certificate and
+   the trusted key certificate. The public part is the ROTPK.
+
+-  **Trusted world key**
+
+   The private part is used to sign the key certificates corresponding to the
+   secure world images (SCP_BL2, BL31 and BL32). The public part is stored in
+   one of the extension fields in the trusted world certificate.
+
+-  **Non-trusted world key**
+
+   The private part is used to sign the key certificate corresponding to the
+   non secure world image (BL33). The public part is stored in one of the
+   extension fields in the trusted world certificate.
+
+-  **BL3X keys**
+
+   For each of SCP_BL2, BL31, BL32 and BL33, the private part is used to
+   sign the content certificate for the BL3X image. The public part is stored
+   in one of the extension fields in the corresponding key certificate.
+
+The following images are included in the CoT:
+
+-  BL1
+-  BL2
+-  SCP_BL2 (optional)
+-  BL31
+-  BL33
+-  BL32 (optional)
+
+The following certificates are used to authenticate the images.
+
+-  **BL2 content certificate**
+
+   It is self-signed with the private part of the ROT key. It contains a hash
+   of the BL2 image.
+
+-  **Trusted key certificate**
+
+   It is self-signed with the private part of the ROT key. It contains the
+   public part of the trusted world key and the public part of the non-trusted
+   world key.
+
+-  **SCP_BL2 key certificate**
+
+   It is self-signed with the trusted world key. It contains the public part of
+   the SCP_BL2 key.
+
+-  **SCP_BL2 content certificate**
+
+   It is self-signed with the SCP_BL2 key. It contains a hash of the SCP_BL2
+   image.
+
+-  **BL31 key certificate**
+
+   It is self-signed with the trusted world key. It contains the public part of
+   the BL31 key.
+
+-  **BL31 content certificate**
+
+   It is self-signed with the BL31 key. It contains a hash of the BL31 image.
+
+-  **BL32 key certificate**
+
+   It is self-signed with the trusted world key. It contains the public part of
+   the BL32 key.
+
+-  **BL32 content certificate**
+
+   It is self-signed with the BL32 key. It contains a hash of the BL32 image.
+
+-  **BL33 key certificate**
+
+   It is self-signed with the non-trusted world key. It contains the public
+   part of the BL33 key.
+
+-  **BL33 content certificate**
+
+   It is self-signed with the BL33 key. It contains a hash of the BL33 image.
+
+The SCP_BL2 and BL32 certificates are optional, but they must be present if the
+corresponding SCP_BL2 or BL32 images are present.
+
+Trusted Board Boot Sequence
+---------------------------
+
+The CoT is verified through the following sequence of steps. The system panics
+if any of the steps fail.
+
+-  BL1 loads and verifies the BL2 content certificate. The issuer public key is
+   read from the verified certificate. A hash of that key is calculated and
+   compared with the hash of the ROTPK read from the trusted root-key storage
+   registers. If they match, the BL2 hash is read from the certificate.
+
+   .. note::
+      The matching operation is platform specific and is currently
+      unimplemented on the Arm development platforms.
+
+-  BL1 loads the BL2 image. Its hash is calculated and compared with the hash
+   read from the certificate. Control is transferred to the BL2 image if all
+   the comparisons succeed.
+
+-  BL2 loads and verifies the trusted key certificate. The issuer public key is
+   read from the verified certificate. A hash of that key is calculated and
+   compared with the hash of the ROTPK read from the trusted root-key storage
+   registers. If the comparison succeeds, BL2 reads and saves the trusted and
+   non-trusted world public keys from the verified certificate.
+
+The next two steps are executed for each of the SCP_BL2, BL31 & BL32 images.
+The steps for the optional SCP_BL2 and BL32 images are skipped if these images
+are not present.
+
+-  BL2 loads and verifies the BL3x key certificate. The certificate signature
+   is verified using the trusted world public key. If the signature
+   verification succeeds, BL2 reads and saves the BL3x public key from the
+   certificate.
+
+-  BL2 loads and verifies the BL3x content certificate. The signature is
+   verified using the BL3x public key. If the signature verification succeeds,
+   BL2 reads and saves the BL3x image hash from the certificate.
+
+The next two steps are executed only for the BL33 image.
+
+-  BL2 loads and verifies the BL33 key certificate. If the signature
+   verification succeeds, BL2 reads and saves the BL33 public key from the
+   certificate.
+
+-  BL2 loads and verifies the BL33 content certificate. If the signature
+   verification succeeds, BL2 reads and saves the BL33 image hash from the
+   certificate.
+
+The next step is executed for all the boot loader images.
+
+-  BL2 calculates the hash of each image. It compares it with the hash obtained
+   from the corresponding content certificate. The image authentication succeeds
+   if the hashes match.
+
+The Trusted Board Boot implementation spans both generic and platform-specific
+BL1 and BL2 code, and in tool code on the host build machine. The feature is
+enabled through use of specific build flags as described in
+:ref:`Build Options`.
+
+On the host machine, a tool generates the certificates, which are included in
+the FIP along with the boot loader images. These certificates are loaded in
+Trusted SRAM using the IO storage framework. They are then verified by an
+Authentication module included in TF-A.
+
+The mechanism used for generating the FIP and the Authentication module are
+described in the following sections.
+
+Authentication Framework
+------------------------
+
+The authentication framework included in TF-A provides support to implement
+the desired trusted boot sequence. Arm platforms use this framework to
+implement the boot requirements specified in the
+`Trusted Board Boot Requirements (TBBR)`_ document.
+
+More information about the authentication framework can be found in the
+:ref:`Authentication Framework & Chain of Trust` document.
+
+Certificate Generation Tool
+---------------------------
+
+The ``cert_create`` tool is built and runs on the host machine as part of the
+TF-A build process when ``GENERATE_COT=1``. It takes the boot loader images
+and keys as inputs (keys must be in PEM format) and generates the
+certificates (in DER format) required to establish the CoT. New keys can be
+generated by the tool in case they are not provided. The certificates are then
+passed as inputs to the ``fiptool`` utility for creating the FIP.
+
+The certificates are also stored individually in the output build directory.
+
+The tool resides in the ``tools/cert_create`` directory. It uses the OpenSSL SSL
+library version to generate the X.509 certificates. The specific version of the
+library that is required is given in the :ref:`Prerequisites` document.
+
+Instructions for building and using the tool can be found at
+:ref:`tools_build_cert_create`.
+
+Authenticated Encryption Framework
+----------------------------------
+
+The authenticated encryption framework included in TF-A provides support to
+implement the optional firmware encryption feature. This feature can be
+optionally enabled on platforms to implement the optional requirement:
+R060_TBBR_FUNCTION as specified in the `Trusted Board Boot Requirements (TBBR)`_
+document.
+
+Firmware Encryption Tool
+------------------------
+
+The ``encrypt_fw`` tool is built and runs on the host machine as part of the
+TF-A build process when ``DECRYPTION_SUPPORT != none``. It takes the plain
+firmware image as input and generates the encrypted firmware image which can
+then be passed as input to the ``fiptool`` utility for creating the FIP.
+
+The encrypted firmwares are also stored individually in the output build
+directory.
+
+The tool resides in the ``tools/encrypt_fw`` directory. It uses OpenSSL SSL
+library version 1.0.1 or later to do authenticated encryption operation.
+Instructions for building and using the tool can be found in the
+:ref:`tools_build_enctool`.

+TF-A CMake buildsystem
+======================
+
+:Author: Balint Dobszay
+:Organization: Arm Limited
+:Contact: Balint Dobszay <balint.dobszay@arm.com>
+:Status: Accepted
+
+.. contents:: Table of Contents
+
+Abstract
+--------
+This document presents a proposal for a new buildsystem for TF-A using CMake,
+and as part of this a reusable CMake framework for embedded projects. For a
+summary about the proposal, please see the `Phabricator wiki page
+<https://developer.trustedfirmware.org/w/tf_a/cmake-buildsystem-proposal/>`_. As
+mentioned there, the proposal consists of two phases. The subject of this
+document is the first phase only.
+
+Introduction
+------------
+The current Makefile based buildsystem of TF-A has become complicated and hard
+to maintain, there is a need for a new, more flexible solution. The proposal is
+to use CMake language for the new buildsystem. The main reasons of this decision
+are the following:
+
+* It is a well-established, mature tool, widely accepted by open-source
+  projects.
+* TF-M is already using CMake, reducing fragmentation for tf.org projects can be
+  beneficial.
+* CMake has various advantages over Make, e.g.:
+
+  * Host and target system agnostic project.
+  * CMake project is scalable, supports project modularization.
+  * Supports software integration.
+  * Out-of-the-box support for integration with several tools (e.g. project
+    generation for various IDEs, integration with cppcheck, etc).
+
+Of course there are drawbacks too:
+
+* Language is problematic (e.g. variable scope).
+* Not embedded approach.
+
+To overcome these and other problems, we need to create workarounds for some
+tasks, wrap CMake functions, etc. Since this functionality can be useful in
+other embedded projects too, it is beneficial to collect the new code into a
+reusable framework and store this in a separate repository. The following
+diagram provides an overview of the framework structure:
+
+|Framework structure|
+
+Main features
+-------------
+
+Structured configuration description
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+In the current Makefile system the build configuration description, validation,
+processing, and the target creation, source file description are mixed and
+spread across several files. One of the goals of the framework is to organize
+this.
+
+The framework provides a solution to describe the input build parameters, flags,
+macros, etc. in a structured way. It contains two utilities for this purpose:
+
+* Map: simple key-value pair implementation.
+* Group: collection of related maps.
+
+The related parameters shall be packed into a group (or "setting group"). The
+setting groups shall be defined and filled with content in config files.
+Currently the config files are created and edited manually, but later a
+configuration management tool (e.g. Kconfig) shall be used to generate these
+files. Therefore, the framework does not contain parameter validation and
+conflict checking, these shall be handled by the configuration tool.
+
+Target description
+^^^^^^^^^^^^^^^^^^
+The framework provides an API called STGT ('simple target') to describe the
+targets, i.e. what is the build output, what source files are used, what
+libraries are linked, etc. The API wraps the CMake target functions, and also
+extends the built-in functionality, it can use the setting groups described in
+the previous section. A group can be applied onto a target, i.e. a collection of
+macros, flags, etc. can be applied onto the given output executable/library.
+This provides a more granular way than the current Makefile system where most of
+these are global and applied onto each target.
+
+Compiler abstraction
+^^^^^^^^^^^^^^^^^^^^
+Apart from the built-in CMake usage of the compiler, there are some common tasks
+that CMake does not solve (e.g. preprocessing a file). For these tasks the
+framework uses wrapper functions instead of direct calls to the compiler. This
+way it is not tied to one specific compiler.
+
+External tools
+^^^^^^^^^^^^^^
+In the TF-A buildsystem some external tools are used, e.g. fiptool for image
+generation or dtc for device tree compilation. These tools have to be found
+and/or built by the framework. For this, the CMake find_package functionality is
+used, any other necessary tools can be added later.
+
+Workflow
+--------
+The following diagram demonstrates the development workflow using the framework:
+
+|Framework workflow|
+
+The process can be split into two main phases:
+
+In the provisioning phase, first we have to obtain the necessary resources, i.e.
+clone the code repository and other dependencies. Next we have to do the
+configuration, preferably using a config tool like KConfig.
+
+In the development phase first we run CMake, which will generate the buildsystem
+using the selected generator backend (currently only the Makefile generator is
+supported). After this we run the selected build tool which in turn calls the
+compiler, linker, packaging tool, etc. Finally we can run and debug the output
+executables.
+
+Usually during development only the steps in this second phase have to be
+repeated, while the provisioning phase needs to be done only once (or rarely).
+
+Example
+-------
+This is a short example for the basic framework usage.
+
+First, we create a setting group called *mem_conf* and fill it with several
+parameters. It is worth noting the difference between *CONFIG* and *DEFINE*
+types: the former is only a CMake domain option, the latter is only a C language
+macro.
+
+Next, we create a target called *fw1* and add the *mem_conf* setting group to
+it. This means that all source and header files used by the target will have all
+the parameters declared in the setting group. Then we set the target type to
+executable, and add some source files. Since the target has the parameters from
+the settings group, we can use it for conditionally adding source files. E.g.
+*dram_controller.c* will only be added if MEM_TYPE equals dram.
+
+.. code-block:: cmake
+
+   group_new(NAME mem_conf)
+   group_add(NAME mem_conf TYPE DEFINE KEY MEM_SIZE VAL 1024)
+   group_add(NAME mem_conf TYPE CONFIG DEFINE KEY MEM_TYPE VAL dram)
+   group_add(NAME mem_conf TYPE CFLAG KEY -Os)
+
+   stgt_create(NAME fw1)
+   stgt_add_setting(NAME fw1 GROUPS mem_conf)
+   stgt_set_target(NAME fw1 TYPE exe)
+
+   stgt_add_src(NAME fw1 SRC
+       ${CMAKE_SOURCE_DIR}/main.c
+   )
+
+   stgt_add_src_cond(NAME fw1 KEY MEM_TYPE VAL dram SRC
+       ${CMAKE_SOURCE_DIR}/dram_controller.c

+Enhance Context Management library for EL3 firmware
+===================================================
+
+:Authors: Soby Mathew & Zelalem Aweke
+:Organization: Arm Limited
+:Contact: Soby Mathew <soby.mathew@arm.com> & Zelalem Aweke <zelalem.aweke@arm.com>
+:Status: RFC
+
+.. contents:: Table of Contents
+
+Introduction
+------------
+The context management library in TF-A provides the basic CPU context
+initialization and management routines for use by different components
+in EL3 firmware. The original design of the library was done keeping in
+mind the 2 world switch and hence this design pattern has been extended to
+keep up with growing requirements of EL3 firmware. With the introduction
+of a new Realm world and a separate Root world for EL3 firmware, it is clear
+that this library needs to be refactored to cater for future enhancements and
+reduce chances of introducing error in code. This also aligns with the overall
+goal of reducing EL3 firmware complexity and footprint.
+
+It is expected that the suggestions below could have legacy implications and
+hence we are mainly targeting SPM/RMM based systems. It is expected that these
+legacy issues will need to be sorted out as part of implementation on a case
+by case basis.
+
+Design Principles
+-----------------
+The below section lays down the design principles for re-factoring the context
+management library :
+
+(1) **Decentralized model for context mgmt**
+
+    Both the Secure and Realm worlds have associated dispatcher component in
+    EL3 firmware to allow management of their respective worlds. Allowing the
+    dispatcher to own the context for their respective world and moving away
+    from a centralized policy management by context management library will
+    remove the world differentiation code in the library. This also means that
+    the library will not be responsible for CPU feature enablement for
+    Secure and Realm worlds. See point 3 and 4 for more details.
+
+    The Non Secure world does not have a dispatcher component and hence EL3
+    firmware (BL31)/context management library needs to have routines to help
+    initialize the Non Secure world context.
+
+(2) **EL3 should only initialize immediate used lower EL**
+
+    Due to the way TF-A evolved, from EL3 interacting with an S-EL1 payload to
+    SPM in S-EL2, there is some code initializing S-EL1 registers which is
+    probably redundant when SPM is present in S-EL2. As a principle, EL3
+    firmware should only initialize the next immediate lower EL in use.
+    If EL2 needs to be skipped and is not to be used at runtime, then
+    EL3 can do the bare minimal EL2 init and init EL1 to prepare for EL3 exit.
+    It is expected that this skip EL2 configuration is only needed for NS
+    world to support legacy Android deployments. It is worth removing this
+    `skip EL2 for Non Secure` config support if this is no longer used.
+
+(3) **Maintain EL3 sysregs which affect lower EL within CPU context**
+
+    The CPU context contains some EL3 sysregs and gets applied on a per-world
+    basis (eg: cptr_el3, scr_el3, zcr_el3 is part of the context
+    because different settings need to be applied between each world).
+    But this design pattern is not enforced in TF-A. It is possible to directly
+    modify EL3 sysreg dynamically during the transition between NS and Secure
+    worlds. Having multiple ways of manipulating EL3 sysregs for different
+    values between the worlds is flaky and error prone. The proposal is to
+    enforce the rule that any EL3 sysreg which can be different between worlds
+    is maintained in the CPU Context. Once the context is initialized the
+    EL3 sysreg values corresponding to the world being entered will be restored.
+
+(4) **Allow more flexibility for Dispatchers to select feature set to save and restore**
+
+    The current functions for EL2 CPU context save and restore is a single
+    function which takes care of saving and restoring all the registers for
+    EL2. This method is inflexible and it does not allow to dynamically detect
+    CPU features to select registers to save and restore. It also assumes that
+    both Realm and Secure world will have the same feature set enabled from
+    EL3 at runtime and makes it hard to enable different features for each
+    world. The framework should cater for selective save and restore of CPU
+    registers which can be controlled by the dispatcher.
+
+    For the implementation, this could mean that there is a separate assembly
+    save and restore routine corresponding to Arch feature. The memory allocation
+    within the CPU Context for each set of registers will be controlled by a
+    FEAT_xxx build option. It is a valid configuration to have
+    context memory allocated but not used at runtime based on feature detection
+    at runtime or the platform owner has decided not to enable the feature
+    for the particular world.
+
+Context Allocation and Initialization
+-------------------------------------
+
+|context_mgmt_abs|
+
+.. |context_mgmt_abs| image::
+   ../resources/diagrams/context_management_abs.png
+
+The above figure shows how the CPU context is allocated within TF-A. The
+allocation for Secure and Realm world is by the respective dispatcher. In the case
+of NS world, the context is allocated by the PSCI lib. This scheme allows TF-A
+to be built in various configurations (with or without Secure/Realm worlds) and
+will result in optimal memory footprint. The Secure and Realm world contexts are
+initialized by invoking context management library APIs which then initialize
+each world based on conditional evaluation of the security state of the
+context. The proposal here is to move the conditional initialization
+of context for Secure and Realm worlds to their respective dispatchers and
+have the library do only the common init needed. The library can export
+helpers to initialize registers corresponding to certain features but
+should not try to do different initialization between the worlds. The library
+can also export helpers for initialization of NS CPU Context since there is no
+dispatcher for that world.
+
+This implies that any world specific code in context mgmt lib should now be
+migrated to the respective "owners". To maintain compatibility with legacy, the
+current functions can be retained in the lib and perhaps define new ones for
+use by SPMD and RMMD. The details of this can be worked out during
+implementation.
+
+Introducing Root Context
+------------------------
+Till now, we have been ignoring the fact that Root world (or EL3) itself could
+have some settings which are distinct from NS/S/Realm worlds. In this case,
+Root world itself would need to maintain some sysregs settings for its own
+execution and would need to use sysregs of lower EL (eg: PAuth, pmcr) to enable
+some functionalities in EL3. The current sequence for context save and restore
+in TF-A is as given below:
+
+|context_mgmt_existing|
+
+.. |context_mgmt_existing| image::
+   ../resources/diagrams/context_mgmt_existing.png
+
+Note1: The EL3 CPU context is not a homogenous collection of EL3 sysregs but
+a collection of EL3 and some other lower EL registers. The save and restore
+is also not done homogenously but based on the objective of using the
+particular register.
+
+Note2: The EL1 context save and restore can possibly be removed when switching
+to S-EL2 as SPM can take care of saving the incoming NS EL1 context.
+
+It can be seen that the EL3 sysreg values applied while the execution is in Root
+world corresponds to the world it came from (eg: if entering EL3 from NS world,
+the sysregs correspond to the values in NS context). There is a case that EL3
+itself may have some settings to apply for various reasons. A good example for
+this is the cptr_el3 regsiter. Although FPU traps need to be disabled for
+Non Secure, Secure and Realm worlds, the EL3 execution itself may keep the trap
+enabled for the sake of robustness. Another example is, if the MTE feature
+is enabled for a particular world, this feature will be enabled for Root world
+as well when entering EL3 from that world. The firmware at EL3 may not
+be expecting this feature to be enabled and may cause unwanted side-effects
+which could be problematic. Thus it would be more robust if Root world is not
+subject to EL3 sysreg values from other worlds but maintains its own values
+which is stable and predictable throughout root world execution.
+
+There is also the case that when EL3 would like to make use of some
+Architectural feature(s) or do some security hardening, it might need
+programming of some lower EL sysregs. For example, if EL3 needs to make
+use of Pointer Authentication (PAuth) feature, it needs to program
+its own PAuth Keys during execution at EL3. Hence EL3 needs its
+own copy of PAuth registers which needs to be restored on every
+entry to EL3. A similar case can be made for DIT bit in PSTATE,
+or use of SP_EL0 for C Runtime Stack at EL3.
+
+The proposal here is to maintain a separate root world CPU context
+which gets applied for Root world execution. This is not the full
+CPU_Context, but subset of EL3 sysregs (`el3_sysreg`) and lower EL
+sysregs (`root_exc_context`) used by EL3. The save and restore
+sequence for this Root context would need to be done in
+an optimal way. The `el3_sysreg` does not need to be saved
+on EL3 Exit and possibly only some registers in `root_exc_context`
+of Root world context would need to be saved on EL3 exit (eg: SP_EL0).
+
+The new sequence for world switch including Root world context would
+be as given below :
+
+|context_mgmt_proposed|
+
+.. |context_mgmt_proposed| image::
+   ../resources/diagrams/context_mgmt_proposed.png
+
+Having this framework in place will allow Root world to make use of lower EL
+registers easily for its own purposes and also have a fixed EL3 sysreg setting
+which is not affected by the settings of other worlds. This will unify the
+Root world register usage pattern for its own execution and remove some
+of the adhoc usages in code.
+
+Conclusion
+----------
+Of all the proposals, the introduction of Root world context would likely need
+further prototyping to confirm the design and we will need to measure the
+performance and memory impact of this change. Other changes are incremental
+improvements which are thought to have negligible impact on EL3 performance.

+DRTM Proof of Concept
+=====================
+
+Dynamic Root of Trust for Measurement (DRTM) begins a new trust environment
+by measuring and executing a protected payload.
+
+Static Root of Trust for Measurement (SRTM)/Measured Boot implementation,
+currently used by TF-A covers all firmwares, from the boot ROM to the normal
+world bootloader. As a whole, they make up the system's TCB. These boot
+measurements allow attesting to what software is running on the system and
+enable enforcing security policies.
+
+As the boot chain grows or firmware becomes dynamically extensible,
+establishing an attestable TCB becomes more challenging. DRTM  provides a
+solution to this problem by allowing measurement chains to be started at
+any time. As these measurements are stored separately from the boot-time
+measurements, they reduce the size of the TCB, which helps reduce the attack
+surface and the risk of untrusted code executing, which could compromise
+the security of the system.
+
+Components
+~~~~~~~~~~
+
+   - **DCE-Preamble**: The DCE Preamble prepares the platform for DRTM by
+     doing any needed configuration, loading the target payload image(DLME),
+     and preparing input parameters needed by DRTM. Finally, it invokes the
+     DL Event to start the dynamic launch.
+
+   - **D-CRTM**: The D-CRTM is the trust anchor (or root of trust) for the
+     DRTM boot sequence and is where the dynamic launch starts. The D-CRTM
+     must be implemented as a trusted agent in the system. The D-CRTM
+     initializes the TPM for DRTM and prepares the environment for the next
+     stage of DRTM, the DCE. The D-CRTM measures the DCE, verifies its
+     signature, and transfers control to it.
+
+   - **DCE**: The DCE executes on an application core. The DCE verifies the
+     system’s state, measures security-critical attributes of the system,
+     prepares the memory region for the target payload, measures the payload,
+     and finally transfers control to the payload.
+
+   - **DLME**: The protected payload is referred to as the Dynamically Launched
+     Measured Environment, or DLME. The DLME begins execution in a safe state,
+     with a single thread of execution, DMA protections, and interrupts
+     disabled. The DCE provides data to the DLME that it can use to verify the
+     configuration of the system.
+
+In this proof of concept, DCE and D-CRTM are implemented in BL31 and
+DCE-Preamble and DLME are implemented in UEFI application. A DL Event is
+triggered as a SMC by DCE-Preamble and handled by D-CRTM, which launches the
+DLME via DCE.
+
+This manual provides instructions to build TF-A code with pre-buit EDK2
+and DRTM UEFI application.
+
+Building the PoC for the Arm FVP platform
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+(1) Use the below command to clone TF-A source code -
+
+.. code:: shell
+
+   $ git clone https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git
+
+(2) There are prebuilt binaries required to execute the DRTM implementation
+    in the `prebuilts-drtm-bins`_.
+    Download EDK2  *FVP_AARCH64_EFI.fd* and UEFI DRTM application *test-disk.img*
+    binary from `prebuilts-drtm-bins`_.
+
+(3) Build the TF-A code using below command
+
+.. code:: shell
+
+   $ make CROSS_COMPILE=aarch64-none-elf- ARM_ROTPK_LOCATION=devel_rsa

+     MBEDTLS_DIR=</path/to/mbedTLS-source> USE_ROMLIB=1 all fip
+
+Running DRTM UEFI application on the Armv8-A AEM FVP
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+To run the DRTM test application along with DRTM implementation in BL31,
+you need an FVP model. Please use the version of FVP_Base_RevC-2xAEMvA model
+advertised in the TF-A documentation.
+
+.. code:: shell
+
+    FVP_Base_RevC-2xAEMvA \
+    --data cluster0.cpu0=</path/to/romlib.bin>@0x03ff2000 \

+    -C pctl.startup=0.0.0.0 \
+    -Q 1000 \
+    "$@"
+
+The bottom of the output from *uart1* should look something like the

+Interaction between Measured Boot and an fTPM (PoC)
+===================================================
+
+Measured Boot is the process of cryptographically measuring the code and
+critical data used at boot time, for example using a TPM, so that the
+security state can be attested later.
+
+The current implementation of the driver included in Trusted Firmware-A
+(TF-A) stores the measurements into a `TGC event log`_ in secure
+memory. No other means of recording measurements (such as a discrete TPM) is
+supported right now.
+
+The driver also provides mechanisms to pass the Event Log to normal world if
+needed.
+
+This manual provides instructions to build a proof of concept (PoC) with the
+sole intention of showing how Measured Boot can be used in conjunction with
+a firmware TPM (fTPM) service implemented on top of OP-TEE.
+
+.. note::
+   The instructions given in this document are meant to be used to build
+   a PoC to show how Measured Boot on TF-A can interact with a third
+   party (f)TPM service and they try to be as general as possible. Different
+   platforms might have different needs and configurations (e.g. different
+   SHA algorithms) and they might also use different types of TPM services
+   (or even a different type of service to provide the attestation)
+   and therefore the instuctions given here might not apply in such scenarios.
+
+Components
+~~~~~~~~~~
+
+The PoC is built on top of the `OP-TEE Toolkit`_, which has support to build
+TF-A with support for Measured Boot enabled (and run it on a Foundation Model)
+since commit cf56848.
+
+The aforementioned toolkit builds a set of images that contain all the components
+needed to test that the Event Log was properly created. One of these images will
+contain a third party fTPM service which in turn will be used to process the
+Event Log.
+
+The reason to choose OP-TEE Toolkit to build our PoC around it is mostly
+for convenience. As the fTPM service used is an OP-TEE TA, it was easy to add
+build support for it to the toolkit and then build the PoC around it.
+
+The most relevant components installed in the image that are closely related to
+Measured Boot/fTPM functionality are:
+
+   - **OP-TEE**: As stated earlier, the fTPM service used in this PoC is built as an
+     OP-TEE TA and therefore we need to include the OP-TEE OS image.
+     Support to interfacing with Measured Boot was added to version 3.9.0 of
+     OP-TEE by implementing the ``PTA_SYSTEM_GET_TPM_EVENT_LOG`` syscall, which
+     allows the former to pass a copy of the Event Log to any TA requesting it.
+     OP-TEE knows the location of the Event Log by reading the DTB bindings
+     received from TF-A. Visit :ref:`DTB binding for Event Log properties`
+     for more details on this.
+
+   - **fTPM Service**: We use a third party fTPM service in order to validate
+     the Measured Boot functionality. The chosen fTPM service is a sample
+     implementation for Aarch32 architecture included on the `ms-tpm-20-ref`_
+     reference implementation from Microsoft. The service was updated in order
+     to extend the Measured Boot Event Log at boot up and it uses the
+     aforementioned ``PTA_SYSTEM_GET_TPM_EVENT_LOG`` call to retrieve a copy
+     of the former.
+
+   .. note::
+      Arm does not provide an fTPM implementation. The fTPM service used here
+      is a third party one which has been updated to support Measured Boot
+      service as provided by TF-A. As such, it is beyond the scope of this
+      manual to test and verify the correctness of the output generated by the
+      fTPM service.
+
+   - **TPM Kernel module**: In order to interact with the fTPM service, we need
+     a kernel module to forward the request from user space to the secure world.
+
+   - `tpm2-tools`_: This is a set of tools that allow to interact with the
+     fTPM service. We use this in order to read the PCRs with the measurements.
+
+Building the PoC for the Arm FVP platform
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+As mentioned before, this PoC is based on the OP-TEE Toolkit with some
+extensions to enable Measured Boot and an fTPM service. Therefore, we can rely
+on the instructions to build the original OP-TEE Toolkit. As a general rule,
+the following steps should suffice:
+
+(1) Start by following the `Get and build the solution`_ instructions to build
+    the OP-TEE toolkit. On step 3, you need to get the manifest for FVP
+    platform from the main branch:
+
+    .. code:: shell
+
+       $ repo init -u https://github.com/OP-TEE/manifest.git -m fvp.xml
+
+    Then proceed synching the repos as stated in step 3. Continue following
+    the instructions and stop before step 5.
+
+(2) Next you should obtain the `Armv8-A Foundation Platform (For Linux Hosts Only)`_.
+    The binary should be untar'ed to the root of the repo tree, i.e., like
+    this: ``<fvp-project>/Foundation_Platformpkg``. In the end, after cloning
+    all source code, getting the toolchains and "installing"
+    Foundation_Platformpkg, you should have a folder structure that looks like
+    this:
+
+    .. code:: shell
+
+       $ ls -la
+       total 80
+       drwxrwxr-x 20 tf-a_user tf-a_user 4096 Jul  1 12:16 .

+(3) Now enter into ``ms-tpm-20-ref`` and get its dependencies:
+
+   .. code:: shell
+
+      $ cd ms-tpm-20-ref
+      $ git submodule init
+      $ git submodule update
+      Submodule path 'external/wolfssl': checked out '9c87f979a7f1d3a6d786b260653d566c1d31a1c4'
+
+(4) Now, you should be able to continue with step 5 in "`Get and build the solution`_"
+    instructions. In order to enable support for Measured Boot, you need to
+    set the ``MEASURED_BOOT`` build option:
+
+    .. code:: shell
+
+       $ MEASURED_BOOT=y make -j `nproc`
+
+    .. note::
+       The build process will likely take a long time. It is strongly recommended to
+       pass the ``-j`` option to make to run the process faster.
+
+   After this step, you should be ready to run the image.
+
+Running and using the PoC on the Armv8-A Foundation AEM FVP
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+With everything built, you can now run the image:
+
+.. code:: shell
+
+   $ make run-only
+
+.. note::
+   Using ``make run`` will build and run the image and it can be used instead
+   of simply ``make``. However, once the image is built, it is recommended to
+   use ``make run-only`` to avoid re-running all the building rules, which
+   would take time.
+
+When FVP is launched, two terminal windows will appear. ``FVP terminal_0``
+is the userspace terminal whereas ``FVP terminal_1`` is the counterpart for
+the secure world (where TAs will print their logs, for instance).
+
+Log into the image shell with user ``root``, no password will be required.
+Then we can issue the ``ftpm`` command, which is an alias that
+
+(1) loads the ftpm kernel module and
+
+(2) calls ``tpm2_pcrread``, which will access the fTPM service to read the
+    PCRs.
+
+When loading the ftpm kernel module, the fTPM TA is loaded into the secure
+world. This TA then requests a copy of the Event Log generated during the
+booting process so it can retrieve all the entries on the log and record them
+first thing.
+
+.. note::
+   For this PoC, nothing loaded after BL33 and NT_FW_CONFIG is recorded
+   in the Event Log.
+
+The secure world terminal should show the debug logs for the fTPM service,
+including all the measurements available in the Event Log as they are being
+processed:

+After the fTPM TA is loaded, the call to ``insmod`` issued by the ``ftpm``

+In this PoC we are only interested in PCR0, which must be non-null. This is
+because the boot process records all the images in this PCR (see field ``PCRIndex``
+on the Event Log above). The rest of the records must be 0 at this point.
+
+.. note::
+   The fTPM service used has support only for 16 PCRs, therefore the content
+   of PCRs above 15 can be ignored.
+
+.. note::
+   As stated earlier, Arm does not provide an fTPM implementation and therefore
+   we do not validate here if the content of PCR0 is correct or not. For this
+   PoC, we are only focused on the fact that the event log could be passed to a third
+   party fTPM and its records were properly extended.
+
+Fine-tuning the fTPM TA
+~~~~~~~~~~~~~~~~~~~~~~~
+
+As stated earlier, the OP-TEE Toolkit includes support to build a third party fTPM
+service. The build options for this service are tailored for the PoC and defined in
+the build environment variable ``FTPM_FLAGS`` (see ``<toolkit_home>/build/common.mk``)
+but they can be modified if needed to better adapt it to a specific scenario.
+
+The most relevant options for Measured Boot support are:
+
+   - **CFG_TA_DEBUG**: Enables debug logs in the Terminal_1 console.
+   - **CFG_TEE_TA_LOG_LEVEL**: Defines the log level used for the debug messages.
+   - **CFG_TA_MEASURED_BOOT**: Enables support for measured boot on the fTPM.
+   - **CFG_TA_EVENT_LOG_SIZE**: Defines the size, in bytes, of the larger event log that
+     the fTPM is able to store, as this buffer is allocated at build time. This must be at
+     least the same as the size of the event log generated by TF-A. If this build option
+     is not defined, the fTPM falls back to a default value of 1024 bytes, which is enough
+     for this PoC, so this variable is not defined in FTPM_FLAGS.

+Build Options
+=============
+
+The TF-A build system supports the following build options. Unless mentioned
+otherwise, these options are expected to be specified at the build command
+line and are not to be modified in any component makefiles. Note that the
+build system doesn't track dependency for build options. Therefore, if any of
+the build options are changed from a previous build, a clean build must be
+performed.
+
+.. _build_options_common:
+
+Common build options
+--------------------
+
+-  ``AARCH32_INSTRUCTION_SET``: Choose the AArch32 instruction set that the
+   compiler should use. Valid values are T32 and A32. It defaults to T32 due to
+   code having a smaller resulting size.
+
+-  ``AARCH32_SP`` : Choose the AArch32 Secure Payload component to be built as
+   as the BL32 image when ``ARCH=aarch32``. The value should be the path to the
+   directory containing the SP source, relative to the ``bl32/``; the directory
+   is expected to contain a makefile called ``<aarch32_sp-value>.mk``.
+
+-  ``AMU_RESTRICT_COUNTERS``: Register reads to the group 1 counters will return
+   zero at all but the highest implemented exception level.  Reads from the
+   memory mapped view are unaffected by this control.
+
+-  ``ARCH`` : Choose the target build architecture for TF-A. It can take either
+   ``aarch64`` or ``aarch32`` as values. By default, it is defined to
+   ``aarch64``.
+
+-  ``ARM_ARCH_FEATURE``: Optional Arm Architecture build option which specifies
+   one or more feature modifiers. This option has the form ``[no]feature+...``
+   and defaults to ``none``. It translates into compiler option
+   ``-march=armvX[.Y]-a+[no]feature+...``. See compiler's documentation for the
+   list of supported feature modifiers.
+
+-  ``ARM_ARCH_MAJOR``: The major version of Arm Architecture to target when
+   compiling TF-A. Its value must be numeric, and defaults to 8 . See also,
+   *Armv8 Architecture Extensions* and *Armv7 Architecture Extensions* in
+   :ref:`Firmware Design`.
+
+-  ``ARM_ARCH_MINOR``: The minor version of Arm Architecture to target when
+   compiling TF-A. Its value must be a numeric, and defaults to 0. See also,
+   *Armv8 Architecture Extensions* in :ref:`Firmware Design`.
+
+-  ``BL2``: This is an optional build option which specifies the path to BL2
+   image for the ``fip`` target. In this case, the BL2 in the TF-A will not be
+   built.
+
+-  ``BL2U``: This is an optional build option which specifies the path to
+   BL2U image. In this case, the BL2U in TF-A will not be built.
+
+-  ``BL2_AT_EL3``: This is an optional build option that enables the use of
+   BL2 at EL3 execution level.
+
+-  ``BL2_ENABLE_SP_LOAD``: Boolean option to enable loading SP packages from the
+   FIP. Automatically enabled if ``SP_LAYOUT_FILE`` is provided.
+
+-  ``BL2_IN_XIP_MEM``: In some use-cases BL2 will be stored in eXecute In Place
+   (XIP) memory, like BL1. In these use-cases, it is necessary to initialize
+   the RW sections in RAM, while leaving the RO sections in place. This option
+   enable this use-case. For now, this option is only supported when BL2_AT_EL3
+   is set to '1'.
+
+-  ``BL31``: This is an optional build option which specifies the path to
+   BL31 image for the ``fip`` target. In this case, the BL31 in TF-A will not
+   be built.
+
+-  ``BL31_KEY``: This option is used when ``GENERATE_COT=1``. It specifies the
+   file that contains the BL31 private key in PEM format. If ``SAVE_KEYS=1``,
+   this file name will be used to save the key.
+
+-  ``BL32``: This is an optional build option which specifies the path to
+   BL32 image for the ``fip`` target. In this case, the BL32 in TF-A will not
+   be built.
+
+-  ``BL32_EXTRA1``: This is an optional build option which specifies the path to
+   Trusted OS Extra1 image for the  ``fip`` target.
+
+-  ``BL32_EXTRA2``: This is an optional build option which specifies the path to
+   Trusted OS Extra2 image for the ``fip`` target.
+
+-  ``BL32_KEY``: This option is used when ``GENERATE_COT=1``. It specifies the
+   file that contains the BL32 private key in PEM format. If ``SAVE_KEYS=1``,
+   this file name will be used to save the key.
+
+-  ``BL33``: Path to BL33 image in the host file system. This is mandatory for
+   ``fip`` target in case TF-A BL2 is used.
+
+-  ``BL33_KEY``: This option is used when ``GENERATE_COT=1``. It specifies the
+   file that contains the BL33 private key in PEM format. If ``SAVE_KEYS=1``,
+   this file name will be used to save the key.
+
+-  ``BRANCH_PROTECTION``: Numeric value to enable ARMv8.3 Pointer Authentication
+   and ARMv8.5 Branch Target Identification support for TF-A BL images themselves.
+   If enabled, it is needed to use a compiler that supports the option
+   ``-mbranch-protection``. Selects the branch protection features to use:
+-  0: Default value turns off all types of branch protection
+-  1: Enables all types of branch protection features
+-  2: Return address signing to its standard level
+-  3: Extend the signing to include leaf functions
+-  4: Turn on branch target identification mechanism
+
+   The table below summarizes ``BRANCH_PROTECTION`` values, GCC compilation options
+   and resulting PAuth/BTI features.
+
+   +-------+--------------+-------+-----+
+   | Value |  GCC option  | PAuth | BTI |
+   +=======+==============+=======+=====+
+   |   0   |     none     |   N   |  N  |
+   +-------+--------------+-------+-----+
+   |   1   |   standard   |   Y   |  Y  |
+   +-------+--------------+-------+-----+
+   |   2   |   pac-ret    |   Y   |  N  |
+   +-------+--------------+-------+-----+
+   |   3   | pac-ret+leaf |   Y   |  N  |
+   +-------+--------------+-------+-----+
+   |   4   |     bti      |   N   |  Y  |
+   +-------+--------------+-------+-----+
+
+   This option defaults to 0.
+   Note that Pointer Authentication is enabled for Non-secure world
+   irrespective of the value of this option if the CPU supports it.
+
+-  ``BUILD_MESSAGE_TIMESTAMP``: String used to identify the time and date of the
+   compilation of each build. It must be set to a C string (including quotes
+   where applicable). Defaults to a string that contains the time and date of
+   the compilation.
+
+-  ``BUILD_STRING``: Input string for VERSION_STRING, which allows the TF-A
+   build to be uniquely identified. Defaults to the current git commit id.
+
+-  ``BUILD_BASE``: Output directory for the build. Defaults to ``./build``
+
+-  ``CFLAGS``: Extra user options appended on the compiler's command line in
+   addition to the options set by the build system.
+
+-  ``COLD_BOOT_SINGLE_CPU``: This option indicates whether the platform may
+   release several CPUs out of reset. It can take either 0 (several CPUs may be
+   brought up) or 1 (only one CPU will ever be brought up during cold reset).
+   Default is 0. If the platform always brings up a single CPU, there is no
+   need to distinguish between primary and secondary CPUs and the boot path can
+   be optimised. The ``plat_is_my_cpu_primary()`` and
+   ``plat_secondary_cold_boot_setup()`` platform porting interfaces do not need
+   to be implemented in this case.
+
+-  ``COT``: When Trusted Boot is enabled, selects the desired chain of trust.
+   Defaults to ``tbbr``.
+
+-  ``CRASH_REPORTING``: A non-zero value enables a console dump of processor
+   register state when an unexpected exception occurs during execution of
+   BL31. This option defaults to the value of ``DEBUG`` - i.e. by default
+   this is only enabled for a debug build of the firmware.
+
+-  ``CREATE_KEYS``: This option is used when ``GENERATE_COT=1``. It tells the
+   certificate generation tool to create new keys in case no valid keys are
+   present or specified. Allowed options are '0' or '1'. Default is '1'.
+
+-  ``CTX_INCLUDE_AARCH32_REGS`` : Boolean option that, when set to 1, will cause
+   the AArch32 system registers to be included when saving and restoring the
+   CPU context. The option must be set to 0 for AArch64-only platforms (that
+   is on hardware that does not implement AArch32, or at least not at EL1 and
+   higher ELs). Default value is 1.
+
+-  ``CTX_INCLUDE_EL2_REGS`` : This boolean option provides context save/restore
+   operations when entering/exiting an EL2 execution context. This is of primary
+   interest when Armv8.4-SecEL2 extension is implemented. Default is 0 (disabled).
+   This option must be equal to 1 (enabled) when ``SPD=spmd`` and
+   ``SPMD_SPM_AT_SEL2`` is set.
+
+-  ``CTX_INCLUDE_FPREGS``: Boolean option that, when set to 1, will cause the FP
+   registers to be included when saving and restoring the CPU context. Default
+   is 0.
+
+-  ``CTX_INCLUDE_MTE_REGS``: Numeric value to include Memory Tagging Extension
+   registers in cpu context. This must be enabled, if the platform wants to use
+   this feature in the Secure world and MTE is enabled at ELX. This flag can
+   take values 0 to 2, to align with the ``FEATURE_DETECTION`` mechanism.
+   Default value is 0.
+
+-  ``CTX_INCLUDE_NEVE_REGS``: Numeric value, when set will cause the Armv8.4-NV
+   registers to be saved/restored when entering/exiting an EL2 execution
+   context. This flag can take values 0 to 2, to align with the
+   ``FEATURE_DETECTION`` mechanism. Default value is 0.
+
+-  ``CTX_INCLUDE_PAUTH_REGS``: Numeric value to enable the Pointer
+   Authentication for Secure world. This will cause the ARMv8.3-PAuth registers
+   to be included when saving and restoring the CPU context as part of world
+   switch. This flag can take values 0 to 2, to align with ``FEATURE_DETECTION``
+   mechanism. Default value is 0.
+
+   Note that Pointer Authentication is enabled for Non-secure world irrespective
+   of the value of this flag if the CPU supports it.
+
+-  ``DEBUG``: Chooses between a debug and release build. It can take either 0
+   (release) or 1 (debug) as values. 0 is the default.
+
+-  ``DECRYPTION_SUPPORT``: This build flag enables the user to select the
+   authenticated decryption algorithm to be used to decrypt firmware/s during
+   boot. It accepts 2 values: ``aes_gcm`` and ``none``. The default value of
+   this flag is ``none`` to disable firmware decryption which is an optional
+   feature as per TBBR.
+
+-  ``DISABLE_BIN_GENERATION``: Boolean option to disable the generation
+   of the binary image. If set to 1, then only the ELF image is built.
+   0 is the default.
+
+-  ``DISABLE_MTPMU``: Boolean option to disable FEAT_MTPMU if implemented
+   (Armv8.6 onwards). Its default value is 0 to keep consistency with platforms
+   that do not implement FEAT_MTPMU. For more information on FEAT_MTPMU,
+   check the latest Arm ARM.
+
+-  ``DYN_DISABLE_AUTH``: Provides the capability to dynamically disable Trusted
+   Board Boot authentication at runtime. This option is meant to be enabled only
+   for development platforms. ``TRUSTED_BOARD_BOOT`` flag must be set if this
+   flag has to be enabled. 0 is the default.
+
+-  ``E``: Boolean option to make warnings into errors. Default is 1.
+
+-  ``EL3_PAYLOAD_BASE``: This option enables booting an EL3 payload instead of
+   the normal boot flow. It must specify the entry point address of the EL3
+   payload. Please refer to the "Booting an EL3 payload" section for more
+   details.
+
+-  ``ENABLE_AMU``: Boolean option to enable Activity Monitor Unit extensions.
+   This is an optional architectural feature available on v8.4 onwards. Some
+   v8.2 implementations also implement an AMU and this option can be used to
+   enable this feature on those systems as well. Default is 0.
+
+-  ``ENABLE_AMU_AUXILIARY_COUNTERS``: Enables support for AMU auxiliary counters
+   (also known as group 1 counters). These are implementation-defined counters,
+   and as such require additional platform configuration. Default is 0.
+
+-  ``ENABLE_AMU_FCONF``: Enables configuration of the AMU through FCONF, which
+   allows platforms with auxiliary counters to describe them via the
+   ``HW_CONFIG`` device tree blob. Default is 0.
+
+-  ``ENABLE_ASSERTIONS``: This option controls whether or not calls to ``assert()``
+   are compiled out. For debug builds, this option defaults to 1, and calls to
+   ``assert()`` are left in place. For release builds, this option defaults to 0
+   and calls to ``assert()`` function are compiled out. This option can be set
+   independently of ``DEBUG``. It can also be used to hide any auxiliary code
+   that is only required for the assertion and does not fit in the assertion
+   itself.
+
+-  ``ENABLE_BACKTRACE``: This option controls whether to enable backtrace
+   dumps or not. It is supported in both AArch64 and AArch32. However, in
+   AArch32 the format of the frame records are not defined in the AAPCS and they
+   are defined by the implementation. This implementation of backtrace only
+   supports the format used by GCC when T32 interworking is disabled. For this
+   reason enabling this option in AArch32 will force the compiler to only
+   generate A32 code. This option is enabled by default only in AArch64 debug
+   builds, but this behaviour can be overridden in each platform's Makefile or
+   in the build command line.
+
+-  ``ENABLE_FEAT_AMUv1``: Numeric value to enable access to the HAFGRTR_EL2
+   (Hypervisor Activity Monitors Fine-Grained Read Trap Register) during EL2
+   to EL3 context save/restore operations. This flag can take the values 0 to 2,
+   to align with the ``FEATURE_DETECTION`` mechanism. It is an optional feature
+   available on v8.4 and onwards and must be set to either 1 or 2 alongside
+   ``ENABLE_FEAT_FGT``, to access the HAFGRTR_EL2 register.
+   Default value is ``0``.
+
+-  ``ENABLE_FEAT_AMUv1p1``: Numeric value to enable the ``FEAT_AMUv1p1``
+   extension. ``FEAT_AMUv1p1`` is an optional feature available on Arm v8.6
+   onwards. This flag can take the values 0 to 2, to align with the
+   ``FEATURE_DETECTION`` mechanism. Default value is ``0``.
+
+-  ``ENABLE_FEAT_CSV2_2``: Numeric value to enable the ``FEAT_CSV2_2``
+   extension. It allows access to the SCXTNUM_EL2 (Software Context Number)
+   register during EL2 context save/restore operations. ``FEAT_CSV2_2`` is an
+   optional feature available on Arm v8.0 onwards. This flag can take values
+   0 to 2, to align with the ``FEATURE_DETECTION`` mechanism.
+   Default value is ``0``.
+
+-  ``ENABLE_FEAT_DIT``: Numeric value to enable ``FEAT_DIT`` (Data Independent
+   Timing) extension. It allows setting the ``DIT`` bit of PSTATE in EL3.
+   ``FEAT_DIT`` is a mandatory  architectural feature and is enabled from v8.4
+   and upwards. This flag can take the values 0 to 2, to align  with the
+   ``FEATURE_DETECTION`` mechanism. Default value is ``0``.
+
+-  ``ENABLE_FEAT_ECV``: Numeric value to enable support for the Enhanced Counter
+   Virtualization feature, allowing for access to the CNTPOFF_EL2 (Counter-timer
+   Physical Offset register) during EL2 to EL3 context save/restore operations.
+   Its a mandatory architectural feature and is enabled from v8.6 and upwards.
+   This flag can take the values 0 to 2, to align  with the ``FEATURE_DETECTION``
+   mechanism. Default value is ``0``.
+

+   Its a mandatory architectural feature and is enabled from v8.6 and upwards.
+   This flag can take the values 0 to 2, to align  with the ``FEATURE_DETECTION``
+   mechanism. Default value is ``0``.
+
+-  ``ENABLE_FEAT_HCX``: Numeric value to set the bit SCR_EL3.HXEn in EL3 to
+   allow access to HCRX_EL2 (extended hypervisor control register) from EL2 as
+   well as adding HCRX_EL2 to the EL2 context save/restore operations. Its a
+   mandatory architectural feature and is enabled from v8.7 and upwards. This
+   flag can take the values 0 to 2, to align  with the ``FEATURE_DETECTION``
+   mechanism. Default value is ``0``.
+
+-  ``ENABLE_FEAT_PAN``: Numeric value to enable the ``FEAT_PAN`` (Privileged
+   Access Never) extension. ``FEAT_PAN`` adds a bit to PSTATE, generating a
+   permission fault for any privileged data access from EL1/EL2 to virtual
+   memory address, accessible at EL0, provided (HCR_EL2.E2H=1). It is a

+-  ``ENABLE_FEAT_SB``: Numeric value to enable the ``FEAT_SB`` (Speculation
+   Barrier) extension allowing access to ``sb`` instruction. ``FEAT_SB`` is an
+   optional feature and defaults to ``0`` for pre-Armv8.5 CPUs but are mandatory
+   for Armv8.5 or later CPUs. This flag can take values 0 to 2, to align with
+   ``FEATURE_DETECTION`` mechanism. It is enabled from v8.5 and upwards and if
+   needed could be overidden from platforms explicitly. Default value is ``0``.
+
+-  ``ENABLE_FEAT_SEL2``: Numeric value to enable the ``FEAT_SEL2`` (Secure EL2)
+   extension. ``FEAT_SEL2`` is a mandatory feature available on Arm v8.4.
+   This flag can take values 0 to 2, to align with the ``FEATURE_DETECTION``

+-  ``ENABLE_FEAT_TWED``: Numeric value to enable the ``FEAT_TWED`` (Delayed
+   trapping of WFE Instruction) extension. ``FEAT_TWED`` is a optional feature
+   available on Arm v8.6. This flag can take values 0 to 2, to align with the
+   ``FEATURE_DETECTION`` mechanism. Default is ``0``.
+
+    When ``ENABLE_FEAT_TWED`` is set to ``1``, WFE instruction trapping gets
+    delayed by the amount of value in ``TWED_DELAY``.
+
+-  ``ENABLE_FEAT_VHE``: Numeric value to enable the ``FEAT_VHE`` (Virtualization
+   Host Extensions) extension. It allows access to CONTEXTIDR_EL2 register
+   during EL2 context save/restore operations.``FEAT_VHE`` is a mandatory
+   architectural feature and is enabled from v8.1 and upwards. It can take
+   values 0 to 2, to align  with the ``FEATURE_DETECTION`` mechanism.
+   Default value is ``0``.
+
+-  ``ENABLE_LTO``: Boolean option to enable Link Time Optimization (LTO)
+   support in GCC for TF-A. This option is currently only supported for
+   AArch64. Default is 0.
+
+-  ``ENABLE_MPAM_FOR_LOWER_ELS``: Numeric value to enable lower ELs to use MPAM
+   feature. MPAM is an optional Armv8.4 extension that enables various memory
+   system components and resources to define partitions; software running at
+   various ELs can assign themselves to desired partition to control their
+   performance aspects.
+
+   This flag can take values 0 to 2, to align  with the ``FEATURE_DETECTION``
+   mechanism. When this option is set to ``1`` or ``2``, EL3 allows lower ELs to
+   access their own MPAM registers without trapping into EL3. This option
+   doesn't make use of partitioning in EL3, however. Platform initialisation
+   code should configure and use partitions in EL3 as required. This option
+   defaults to ``0``.
+
+-  ``ENABLE_MPMM``: Boolean option to enable support for the Maximum Power
+   Mitigation Mechanism supported by certain Arm cores, which allows the SoC
+   firmware to detect and limit high activity events to assist in SoC processor
+   power domain dynamic power budgeting and limit the triggering of whole-rail
+   (i.e. clock chopping) responses to overcurrent conditions. Defaults to ``0``.
+
+-  ``ENABLE_MPMM_FCONF``: Enables configuration of MPMM through FCONF, which
+   allows platforms with cores supporting MPMM to describe them via the
+   ``HW_CONFIG`` device tree blob. Default is 0.
+
+-  ``ENABLE_PIE``: Boolean option to enable Position Independent Executable(PIE)
+   support within generic code in TF-A. This option is currently only supported
+   in BL2_AT_EL3, BL31, and BL32 (TSP) for AARCH64 binaries, and in BL32
+   (SP_min) for AARCH32. Default is 0.
+
+-  ``ENABLE_PMF``: Boolean option to enable support for optional Performance
+   Measurement Framework(PMF). Default is 0.
+
+-  ``ENABLE_PSCI_STAT``: Boolean option to enable support for optional PSCI
+   functions ``PSCI_STAT_RESIDENCY`` and ``PSCI_STAT_COUNT``. Default is 0.
+   In the absence of an alternate stat collection backend, ``ENABLE_PMF`` must
+   be enabled. If ``ENABLE_PMF`` is set, the residency statistics are tracked in
+   software.
+
+- ``ENABLE_RME``: Numeric value to enable support for the ARMv9 Realm
+   Management Extension. This flag can take the values 0 to 2, to align with
+   the ``FEATURE_DETECTION`` mechanism. Default value is 0. This is currently
+   an experimental feature.
+
+-  ``ENABLE_RUNTIME_INSTRUMENTATION``: Boolean option to enable runtime
+   instrumentation which injects timestamp collection points into TF-A to
+   allow runtime performance to be measured. Currently, only PSCI is
+   instrumented. Enabling this option enables the ``ENABLE_PMF`` build option
+   as well. Default is 0.
+
+-  ``ENABLE_SME_FOR_NS``: Boolean option to enable Scalable Matrix Extension
+   (SME), SVE, and FPU/SIMD for the non-secure world only. These features share
+   registers so are enabled together. Using this option without
+   ENABLE_SME_FOR_SWD=1 will cause SME, SVE, and FPU/SIMD instructions in secure
+   world to trap to EL3. SME is an optional architectural feature for AArch64
+   and TF-A support is experimental. At this time, this build option cannot be
+   used on systems that have SPD=spmd/SPM_MM or ENABLE_RME, and attempting to
+   build with these options will fail. Default is 0.
+
+-  ``ENABLE_SME_FOR_SWD``: Boolean option to enable the Scalable Matrix
+   Extension for secure world use along with SVE and FPU/SIMD, ENABLE_SME_FOR_NS
+   must also be set to use this. If enabling this, the secure world MUST
+   handle context switching for SME, SVE, and FPU/SIMD registers to ensure that
+   no data is leaked to non-secure world. This is experimental. Default is 0.
+
+-  ``ENABLE_SPE_FOR_LOWER_ELS`` : Boolean option to enable Statistical Profiling
+   extensions. This is an optional architectural feature for AArch64.
+   The default is 1 but is automatically disabled when the target architecture
+   is AArch32.
+
+-  ``ENABLE_SVE_FOR_NS``: Boolean option to enable Scalable Vector Extension
+   (SVE) for the Non-secure world only. SVE is an optional architectural feature
+   for AArch64. Note that when SVE is enabled for the Non-secure world, access
+   to SIMD and floating-point functionality from the Secure world is disabled by
+   default and controlled with ENABLE_SVE_FOR_SWD.
+   This is to avoid corruption of the Non-secure world data in the Z-registers
+   which are aliased by the SIMD and FP registers. The build option is not
+   compatible with the ``CTX_INCLUDE_FPREGS`` build option, and will raise an
+   assert on platforms where SVE is implemented and ``ENABLE_SVE_FOR_NS`` set to
+   1. The default is 1 but is automatically disabled when ENABLE_SME_FOR_NS=1
+   since SME encompasses SVE. At this time, this build option cannot be used on
+   systems that have SPM_MM enabled.
+
+-  ``ENABLE_SVE_FOR_SWD``: Boolean option to enable SVE for the Secure world.
+   SVE is an optional architectural feature for AArch64. Note that this option
+   requires ENABLE_SVE_FOR_NS to be enabled. The default is 0 and it
+   is automatically disabled when the target architecture is AArch32.
+
+-  ``ENABLE_STACK_PROTECTOR``: String option to enable the stack protection
+   checks in GCC. Allowed values are "all", "strong", "default" and "none". The
+   default value is set to "none". "strong" is the recommended stack protection
+   level if this feature is desired. "none" disables the stack protection. For
+   all values other than "none", the ``plat_get_stack_protector_canary()``
+   platform hook needs to be implemented. The value is passed as the last
+   component of the option ``-fstack-protector-$ENABLE_STACK_PROTECTOR``.
+
+-  ``ENCRYPT_BL31``: Binary flag to enable encryption of BL31 firmware. This
+   flag depends on ``DECRYPTION_SUPPORT`` build flag.
+
+-  ``ENCRYPT_BL32``: Binary flag to enable encryption of Secure BL32 payload.
+   This flag depends on ``DECRYPTION_SUPPORT`` build flag.
+
+-  ``ENC_KEY``: A 32-byte (256-bit) symmetric key in hex string format. It could
+   either be SSK or BSSK depending on ``FW_ENC_STATUS`` flag. This value depends
+   on ``DECRYPTION_SUPPORT`` build flag.
+
+-  ``ENC_NONCE``: A 12-byte (96-bit) encryption nonce or Initialization Vector
+   (IV) in hex string format. This value depends on ``DECRYPTION_SUPPORT``
+   build flag.
+
+-  ``ERROR_DEPRECATED``: This option decides whether to treat the usage of
+   deprecated platform APIs, helper functions or drivers within Trusted
+   Firmware as error. It can take the value 1 (flag the use of deprecated
+   APIs as error) or 0. The default is 0.
+
+-  ``EL3_EXCEPTION_HANDLING``: When set to ``1``, enable handling of exceptions
+   targeted at EL3. When set ``0`` (default), no exceptions are expected or
+   handled at EL3, and a panic will result. The exception to this rule is when
+   ``SPMD_SPM_AT_SEL2`` is set to ``1``, in which case, only exceptions
+   occuring during normal world execution, are trapped to EL3. Any exception
+   trapped during secure world execution are trapped to the SPMC. This is
+   supported only for AArch64 builds.
+
+-  ``EVENT_LOG_LEVEL``: Chooses the log level to use for Measured Boot when
+   ``MEASURED_BOOT`` is enabled. For a list of valid values, see ``LOG_LEVEL``.
+   Default value is 40 (LOG_LEVEL_INFO).
+
+-  ``FAULT_INJECTION_SUPPORT``: ARMv8.4 extensions introduced support for fault
+   injection from lower ELs, and this build option enables lower ELs to use
+   Error Records accessed via System Registers to inject faults. This is
+   applicable only to AArch64 builds.
+
+   This feature is intended for testing purposes only, and is advisable to keep
+   disabled for production images.
+
+-  ``FEATURE_DETECTION``: Boolean option to enable the architectural features
+   detection mechanism. It detects whether the Architectural features enabled
+   through feature specific build flags are supported by the PE or not by
+   validating them either at boot phase or at runtime based on the value
+   possessed by the feature flag (0 to 2) and report error messages at an early
+   stage.
+
+   This prevents and benefits us from EL3 runtime exceptions during context save
+   and restore routines guarded by these build flags. Henceforth validating them
+   before their usage provides more control on the actions taken under them.
+
+   The mechanism permits the build flags to take values 0, 1 or 2 and
+   evaluates them accordingly.
+
+   Lets consider ``ENABLE_FEAT_HCX``, build flag for ``FEAT_HCX`` as an example:
+
+   ::
+
+     ENABLE_FEAT_HCX = 0: Feature disabled statically at compile time.
+     ENABLE_FEAT_HCX = 1: Feature Enabled and the flag is validated at boottime.
+     ENABLE_FEAT_HCX = 2: Feature Enabled and the flag is validated at runtime.
+
+   In the above example, if the feature build flag, ``ENABLE_FEAT_HCX`` set to
+   0, feature is disabled statically during compilation. If it is defined as 1,
+   feature is validated, wherein FEAT_HCX is detected at boot time. In case not
+   implemented by the PE, a hard panic is generated. Finally, if the flag is set
+   to 2, feature is validated at runtime.
+
+   Note that the entire implementation is divided into two phases, wherein as
+   as part of phase-1 we are supporting the values 0,1. Value 2 is currently not
+   supported and is planned to be handled explicilty in phase-2 implementation.
+
+   FEATURE_DETECTION macro is disabled by default, and is currently an
+   experimental procedure. Platforms can explicitly make use of this by
+   mechanism, by enabling it to validate whether they have set their build flags
+   properly at an early phase.
+
+-  ``FIP_NAME``: This is an optional build option which specifies the FIP
+   filename for the ``fip`` target. Default is ``fip.bin``.
+
+-  ``FWU_FIP_NAME``: This is an optional build option which specifies the FWU
+   FIP filename for the ``fwu_fip`` target. Default is ``fwu_fip.bin``.
+
+-  ``FW_ENC_STATUS``: Top level firmware's encryption numeric flag, values:
+
+   ::
+
+     0: Encryption is done with Secret Symmetric Key (SSK) which is common
+        for a class of devices.
+     1: Encryption is done with Binding Secret Symmetric Key (BSSK) which is
+        unique per device.
+
+   This flag depends on ``DECRYPTION_SUPPORT`` build flag.
+
+-  ``GENERATE_COT``: Boolean flag used to build and execute the ``cert_create``
+   tool to create certificates as per the Chain of Trust described in
+   :ref:`Trusted Board Boot`. The build system then calls ``fiptool`` to
+   include the certificates in the FIP and FWU_FIP. Default value is '0'.
+
+   Specify both ``TRUSTED_BOARD_BOOT=1`` and ``GENERATE_COT=1`` to include support
+   for the Trusted Board Boot feature in the BL1 and BL2 images, to generate
+   the corresponding certificates, and to include those certificates in the
+   FIP and FWU_FIP.
+
+   Note that if ``TRUSTED_BOARD_BOOT=0`` and ``GENERATE_COT=1``, the BL1 and BL2
+   images will not include support for Trusted Board Boot. The FIP will still
+   include the corresponding certificates. This FIP can be used to verify the
+   Chain of Trust on the host machine through other mechanisms.
+
+   Note that if ``TRUSTED_BOARD_BOOT=1`` and ``GENERATE_COT=0``, the BL1 and BL2
+   images will include support for Trusted Board Boot, but the FIP and FWU_FIP
+   will not include the corresponding certificates, causing a boot failure.
+
+-  ``GICV2_G0_FOR_EL3``: Unlike GICv3, the GICv2 architecture doesn't have
+   inherent support for specific EL3 type interrupts. Setting this build option
+   to ``1`` assumes GICv2 *Group 0* interrupts are expected to target EL3, both
+   by :ref:`platform abstraction layer<platform Interrupt Controller API>` and
+   :ref:`Interrupt Management Framework<Interrupt Management Framework>`.
+   This allows GICv2 platforms to enable features requiring EL3 interrupt type.
+   This also means that all GICv2 Group 0 interrupts are delivered to EL3, and
+   the Secure Payload interrupts needs to be synchronously handed over to Secure
+   EL1 for handling. The default value of this option is ``0``, which means the
+   Group 0 interrupts are assumed to be handled by Secure EL1.
+
+-  ``HANDLE_EA_EL3_FIRST_NS``: When set to ``1``, External Aborts and SError
+   Interrupts, resulting from errors in NS world, will be always trapped in
+   EL3 i.e. in BL31 at runtime. When set to ``0`` (default), these exceptions
+   will be trapped in the current exception level (or in EL1 if the current
+   exception level is EL0).
+
+-  ``HW_ASSISTED_COHERENCY``: On most Arm systems to-date, platform-specific
+   software operations are required for CPUs to enter and exit coherency.
+   However, newer systems exist where CPUs' entry to and exit from coherency
+   is managed in hardware. Such systems require software to only initiate these
+   operations, and the rest is managed in hardware, minimizing active software
+   management. In such systems, this boolean option enables TF-A to carry out
+   build and run-time optimizations during boot and power management operations.
+   This option defaults to 0 and if it is enabled, then it implies
+   ``WARMBOOT_ENABLE_DCACHE_EARLY`` is also enabled.
+
+   If this flag is disabled while the platform which TF-A is compiled for
+   includes cores that manage coherency in hardware, then a compilation error is
+   generated. This is based on the fact that a system cannot have, at the same
+   time, cores that manage coherency in hardware and cores that don't. In other
+   words, a platform cannot have, at the same time, cores that require
+   ``HW_ASSISTED_COHERENCY=1`` and cores that require
+   ``HW_ASSISTED_COHERENCY=0``.
+
+   Note that, when ``HW_ASSISTED_COHERENCY`` is enabled, version 2 of
+   translation library (xlat tables v2) must be used; version 1 of translation
+   library is not supported.
+
+-  ``INVERTED_MEMMAP``: memmap tool print by default lower addresses at the
+   bottom, higher addresses at the top. This build flag can be set to '1' to
+   invert this behavior. Lower addresses will be printed at the top and higher
+   addresses at the bottom.
+
+-  ``JUNO_AARCH32_EL3_RUNTIME``: This build flag enables you to execute EL3
+   runtime software in AArch32 mode, which is required to run AArch32 on Juno.
+   By default this flag is set to '0'. Enabling this flag builds BL1 and BL2 in
+   AArch64 and facilitates the loading of ``SP_MIN`` and BL33 as AArch32 executable
+   images.
+
+-  ``KEY_ALG``: This build flag enables the user to select the algorithm to be
+   used for generating the PKCS keys and subsequent signing of the certificate.
+   It accepts 5 values: ``rsa``, ``rsa_1_5``, ``ecdsa``, ``ecdsa-brainpool-regular``
+   and ``ecdsa-brainpool-twisted``. The option ``rsa_1_5`` is the legacy PKCS#1
+   RSA 1.5 algorithm which is not TBBR compliant and is retained only for
+   compatibility. The default value of this flag is ``rsa`` which is the TBBR
+   compliant PKCS#1 RSA 2.1 scheme.
+
+-  ``KEY_SIZE``: This build flag enables the user to select the key size for
+   the algorithm specified by ``KEY_ALG``. The valid values for ``KEY_SIZE``
+   depend on the chosen algorithm and the cryptographic module.
+
+   +---------------------------+------------------------------------+
+   |         KEY_ALG           |        Possible key sizes          |
+   +===========================+====================================+
+   |           rsa             | 1024 , 2048 (default), 3072, 4096* |

+   |  ecdsa-brainpool-regular  |            unavailable             |
+   +---------------------------+------------------------------------+
+   |  ecdsa-brainpool-twisted  |            unavailable             |
+   +---------------------------+------------------------------------+
+
+
+   * Only 2048 bits size is available with CryptoCell 712 SBROM release 1.
+     Only 3072 bits size is available with CryptoCell 712 SBROM release 2.
+
+-  ``HASH_ALG``: This build flag enables the user to select the secure hash
+   algorithm. It accepts 3 values: ``sha256``, ``sha384`` and ``sha512``.
+   The default value of this flag is ``sha256``.
+
+-  ``LDFLAGS``: Extra user options appended to the linkers' command line in
+   addition to the one set by the build system.
+
+-  ``LOG_LEVEL``: Chooses the log level, which controls the amount of console log
+   output compiled into the build. This should be one of the following:
+
+   ::
+
+       0  (LOG_LEVEL_NONE)
+       10 (LOG_LEVEL_ERROR)
+       20 (LOG_LEVEL_NOTICE)
+       30 (LOG_LEVEL_WARNING)
+       40 (LOG_LEVEL_INFO)
+       50 (LOG_LEVEL_VERBOSE)
+
+   All log output up to and including the selected log level is compiled into
+   the build. The default value is 40 in debug builds and 20 in release builds.
+
+-  ``MEASURED_BOOT``: Boolean flag to include support for the Measured Boot
+   feature. This flag can be enabled with ``TRUSTED_BOARD_BOOT`` in order to
+   provide trust that the code taking the measurements and recording them has
+   not been tampered with.
+
+   This option defaults to 0.
+
+-  ``DRTM_SUPPORT``: Boolean flag to enable support for Dynamic Root of Trust
+   for Measurement (DRTM). This feature has trust dependency on BL31 for taking
+   the measurements and recording them as per `PSA DRTM specification`_. For
+   platforms which use BL2 to load/authenticate BL31 ``TRUSTED_BOARD_BOOT`` can
+   be used and for the platforms which use ``RESET_TO_BL31`` platform owners
+   should have mechanism to authenticate BL31.
+
+   This option defaults to 0.
+
+-  ``NON_TRUSTED_WORLD_KEY``: This option is used when ``GENERATE_COT=1``. It
+   specifies the file that contains the Non-Trusted World private key in PEM
+   format. If ``SAVE_KEYS=1``, this file name will be used to save the key.
+
+-  ``NS_BL2U``: Path to NS_BL2U image in the host file system. This image is
+   optional. It is only needed if the platform makefile specifies that it
+   is required in order to build the ``fwu_fip`` target.
+
+-  ``NS_TIMER_SWITCH``: Enable save and restore for non-secure timer register
+   contents upon world switch. It can take either 0 (don't save and restore) or
+   1 (do save and restore). 0 is the default. An SPD may set this to 1 if it
+   wants the timer registers to be saved and restored.
+
+-  ``OVERRIDE_LIBC``: This option allows platforms to override the default libc
+   for the BL image. It can be either 0 (include) or 1 (remove). The default
+   value is 0.
+
+-  ``PL011_GENERIC_UART``: Boolean option to indicate the PL011 driver that
+   the underlying hardware is not a full PL011 UART but a minimally compliant
+   generic UART, which is a subset of the PL011. The driver will not access
+   any register that is not part of the SBSA generic UART specification.
+   Default value is 0 (a full PL011 compliant UART is present).
+
+-  ``PLAT``: Choose a platform to build TF-A for. The chosen platform name
+   must be subdirectory of any depth under ``plat/``, and must contain a
+   platform makefile named ``platform.mk``. For example, to build TF-A for the
+   Arm Juno board, select PLAT=juno.
+
+-  ``PRELOADED_BL33_BASE``: This option enables booting a preloaded BL33 image
+   instead of the normal boot flow. When defined, it must specify the entry
+   point address for the preloaded BL33 image. This option is incompatible with
+   ``EL3_PAYLOAD_BASE``. If both are defined, ``EL3_PAYLOAD_BASE`` has priority
+   over ``PRELOADED_BL33_BASE``.
+
+-  ``PROGRAMMABLE_RESET_ADDRESS``: This option indicates whether the reset
+   vector address can be programmed or is fixed on the platform. It can take
+   either 0 (fixed) or 1 (programmable). Default is 0. If the platform has a
+   programmable reset address, it is expected that a CPU will start executing
+   code directly at the right address, both on a cold and warm reset. In this
+   case, there is no need to identify the entrypoint on boot and the boot path
+   can be optimised. The ``plat_get_my_entrypoint()`` platform porting interface
+   does not need to be implemented in this case.
+
+-  ``PSCI_EXTENDED_STATE_ID``: As per PSCI1.0 Specification, there are 2 formats
+   possible for the PSCI power-state parameter: original and extended State-ID
+   formats. This flag if set to 1, configures the generic PSCI layer to use the
+   extended format. The default value of this flag is 0, which means by default
+   the original power-state format is used by the PSCI implementation. This flag
+   should be specified by the platform makefile and it governs the return value
+   of PSCI_FEATURES API for CPU_SUSPEND smc function id. When this option is
+   enabled on Arm platforms, the option ``ARM_RECOM_STATE_ID_ENC`` needs to be
+   set to 1 as well.
+
+-  ``RAS_EXTENSION``: Numeric value to enable Armv8.2 RAS features. RAS features
+   are an optional extension for pre-Armv8.2 CPUs, but are mandatory for Armv8.2
+   or later CPUs. This flag can take the values 0 to 2, to align with the
+   ``FEATURE_DETECTION`` mechanism.
+
+   When ``RAS_EXTENSION`` is set to ``1``, ``HANDLE_EA_EL3_FIRST_NS`` must also be
+   set to ``1``.
+
+   This option is disabled by default.
+
+-  ``RESET_TO_BL31``: Enable BL31 entrypoint as the CPU reset vector instead
+   of the BL1 entrypoint. It can take the value 0 (CPU reset to BL1
+   entrypoint) or 1 (CPU reset to BL31 entrypoint).
+   The default value is 0.
+
+-  ``RESET_TO_BL31_WITH_PARAMS``: If ``RESET_TO_BL31`` has been enabled, setting
+   this additional option guarantees that the input registers are not cleared
+   therefore allowing parameters to be passed to the BL31 entrypoint.
+   The default value is 0.
+
+-  ``RESET_TO_SP_MIN``: SP_MIN is the minimal AArch32 Secure Payload provided
+   in TF-A. This flag configures SP_MIN entrypoint as the CPU reset vector
+   instead of the BL1 entrypoint. It can take the value 0 (CPU reset to BL1
+   entrypoint) or 1 (CPU reset to SP_MIN entrypoint). The default value is 0.
+
+-  ``ROT_KEY``: This option is used when ``GENERATE_COT=1``. It specifies the
+   file that contains the ROT private key in PEM format and enforces public key
+   hash generation. If ``SAVE_KEYS=1``, this
+   file name will be used to save the key.
+
+-  ``SAVE_KEYS``: This option is used when ``GENERATE_COT=1``. It tells the
+   certificate generation tool to save the keys used to establish the Chain of
+   Trust. Allowed options are '0' or '1'. Default is '0' (do not save).
+
+-  ``SCP_BL2``: Path to SCP_BL2 image in the host file system. This image is optional.
+   If a SCP_BL2 image is present then this option must be passed for the ``fip``
+   target.
+
+-  ``SCP_BL2_KEY``: This option is used when ``GENERATE_COT=1``. It specifies the
+   file that contains the SCP_BL2 private key in PEM format. If ``SAVE_KEYS=1``,
+   this file name will be used to save the key.
+
+-  ``SCP_BL2U``: Path to SCP_BL2U image in the host file system. This image is
+   optional. It is only needed if the platform makefile specifies that it
+   is required in order to build the ``fwu_fip`` target.
+
+-  ``SDEI_SUPPORT``: Setting this to ``1`` enables support for Software
+   Delegated Exception Interface to BL31 image. This defaults to ``0``.
+
+   When set to ``1``, the build option ``EL3_EXCEPTION_HANDLING`` must also be
+   set to ``1``.
+
+-  ``SEPARATE_CODE_AND_RODATA``: Whether code and read-only data should be
+   isolated on separate memory pages. This is a trade-off between security and
+   memory usage. See "Isolating code and read-only data on separate memory
+   pages" section in :ref:`Firmware Design`. This flag is disabled by default
+   and affects all BL images.
+
+-  ``SEPARATE_NOBITS_REGION``: Setting this option to ``1`` allows the NOBITS
+   sections of BL31 (.bss, stacks, page tables, and coherent memory) to be
+   allocated in RAM discontiguous from the loaded firmware image. When set, the
+   platform is expected to provide definitions for ``BL31_NOBITS_BASE`` and
+   ``BL31_NOBITS_LIMIT``. When the option is ``0`` (the default), NOBITS
+   sections are placed in RAM immediately following the loaded firmware image.
+
+-  ``SEPARATE_BL2_NOLOAD_REGION``: Setting this option to ``1`` allows the
+   NOLOAD sections of BL2 (.bss, stacks, page tables) to be allocated in RAM
+   discontiguous from loaded firmware images. When set, the platform need to
+   provide definitions of ``BL2_NOLOAD_START`` and ``BL2_NOLOAD_LIMIT``. This
+   flag is disabled by default and NOLOAD sections are placed in RAM immediately
+   following the loaded firmware image.
+
+-  ``SMC_PCI_SUPPORT``: This option allows platforms to handle PCI configuration
+   access requests via a standard SMCCC defined in `DEN0115`_. When combined with
+   UEFI+ACPI this can provide a certain amount of OS forward compatibility
+   with newer platforms that aren't ECAM compliant.
+
+-  ``SPD``: Choose a Secure Payload Dispatcher component to be built into TF-A.
+   This build option is only valid if ``ARCH=aarch64``. The value should be
+   the path to the directory containing the SPD source, relative to
+   ``services/spd/``; the directory is expected to contain a makefile called
+   ``<spd-value>.mk``. The SPM Dispatcher standard service is located in
+   services/std_svc/spmd and enabled by ``SPD=spmd``. The SPM Dispatcher
+   cannot be enabled when the ``SPM_MM`` option is enabled.
+
+-  ``SPIN_ON_BL1_EXIT``: This option introduces an infinite loop in BL1. It can
+   take either 0 (no loop) or 1 (add a loop). 0 is the default. This loop stops
+   execution in BL1 just before handing over to BL31. At this point, all
+   firmware images have been loaded in memory, and the MMU and caches are
+   turned off. Refer to the "Debugging options" section for more details.
+
+-  ``SPMC_AT_EL3`` : This boolean option is used jointly with the SPM
+   Dispatcher option (``SPD=spmd``). When enabled (1) it indicates the SPMC
+   component runs at the EL3 exception level. The default value is ``0`` (
+   disabled). This configuration supports pre-Armv8.4 platforms (aka not
+   implementing the ``FEAT_SEL2`` extension). This is an experimental feature.
+
+-  ``SPMD_SPM_AT_SEL2`` : This boolean option is used jointly with the SPM
+   Dispatcher option (``SPD=spmd``). When enabled (1) it indicates the SPMC
+   component runs at the S-EL2 exception level provided by the ``FEAT_SEL2``
+   extension. This is the default when enabling the SPM Dispatcher. When
+   disabled (0) it indicates the SPMC component runs at the S-EL1 execution
+   state or at EL3 if ``SPMC_AT_EL3`` is enabled. The latter configurations
+   support pre-Armv8.4 platforms (aka not implementing the ``FEAT_SEL2``
+   extension).
+
+-  ``SPM_MM`` : Boolean option to enable the Management Mode (MM)-based Secure
+   Partition Manager (SPM) implementation. The default value is ``0``
+   (disabled). This option cannot be enabled (``1``) when SPM Dispatcher is
+   enabled (``SPD=spmd``).
+
+-  ``SP_LAYOUT_FILE``: Platform provided path to JSON file containing the
+   description of secure partitions. The build system will parse this file and
+   package all secure partition blobs into the FIP. This file is not
+   necessarily part of TF-A tree. Only available when ``SPD=spmd``.
+
+-  ``SP_MIN_WITH_SECURE_FIQ``: Boolean flag to indicate the SP_MIN handles
+   secure interrupts (caught through the FIQ line). Platforms can enable
+   this directive if they need to handle such interruption. When enabled,
+   the FIQ are handled in monitor mode and non secure world is not allowed
+   to mask these events. Platforms that enable FIQ handling in SP_MIN shall
+   implement the api ``sp_min_plat_fiq_handler()``. The default value is 0.
+
+-  ``SVE_VECTOR_LEN``: SVE vector length to configure in ZCR_EL3.
+   Platforms can configure this if they need to lower the hardware
+   limit, for example due to asymmetric configuration or limitations of
+   software run at lower ELs. The default is the architectural maximum
+   of 2048 which should be suitable for most configurations, the
+   hardware will limit the effective VL to the maximum physically supported
+   VL.
+
+-  ``TRNG_SUPPORT``: Setting this to ``1`` enables support for True
+   Random Number Generator Interface to BL31 image. This defaults to ``0``.
+
+-  ``TRUSTED_BOARD_BOOT``: Boolean flag to include support for the Trusted Board
+   Boot feature. When set to '1', BL1 and BL2 images include support to load
+   and verify the certificates and images in a FIP, and BL1 includes support
+   for the Firmware Update. The default value is '0'. Generation and inclusion
+   of certificates in the FIP and FWU_FIP depends upon the value of the
+   ``GENERATE_COT`` option.
+
+   .. warning::
+      This option depends on ``CREATE_KEYS`` to be enabled. If the keys
+      already exist in disk, they will be overwritten without further notice.
+
+-  ``TRUSTED_WORLD_KEY``: This option is used when ``GENERATE_COT=1``. It
+   specifies the file that contains the Trusted World private key in PEM
+   format. If ``SAVE_KEYS=1``, this file name will be used to save the key.
+
+-  ``TSP_INIT_ASYNC``: Choose BL32 initialization method as asynchronous or
+   synchronous, (see "Initializing a BL32 Image" section in
+   :ref:`Firmware Design`). It can take the value 0 (BL32 is initialized using
+   synchronous method) or 1 (BL32 is initialized using asynchronous method).
+   Default is 0.
+
+-  ``TSP_NS_INTR_ASYNC_PREEMPT``: A non zero value enables the interrupt
+   routing model which routes non-secure interrupts asynchronously from TSP
+   to EL3 causing immediate preemption of TSP. The EL3 is responsible
+   for saving and restoring the TSP context in this routing model. The
+   default routing model (when the value is 0) is to route non-secure
+   interrupts to TSP allowing it to save its context and hand over
+   synchronously to EL3 via an SMC.
+
+   .. note::
+      When ``EL3_EXCEPTION_HANDLING`` is ``1``, ``TSP_NS_INTR_ASYNC_PREEMPT``
+      must also be set to ``1``.
+
+-  ``TWED_DELAY``: Numeric value to be set in order to delay the trapping of
+   WFE instruction. ``ENABLE_FEAT_TWED`` build option must be enabled to set
+   this delay. It can take values in the range (0-15). Default value is ``0``
+   and based on this value, 2^(TWED_DELAY + 8) cycles will be delayed.
+   Platforms need to explicitly update this value based on their requirements.
+
+-  ``USE_ARM_LINK``: This flag determines whether to enable support for ARM
+   linker. When the ``LINKER`` build variable points to the armlink linker,
+   this flag is enabled automatically. To enable support for armlink, platforms
+   will have to provide a scatter file for the BL image. Currently, Tegra
+   platforms use the armlink support to compile BL3-1 images.
+
+-  ``USE_COHERENT_MEM``: This flag determines whether to include the coherent
+   memory region in the BL memory map or not (see "Use of Coherent memory in
+   TF-A" section in :ref:`Firmware Design`). It can take the value 1
+   (Coherent memory region is included) or 0 (Coherent memory region is
+   excluded). Default is 1.
+
+-  ``USE_DEBUGFS``: When set to 1 this option activates an EXPERIMENTAL feature
+   exposing a virtual filesystem interface through BL31 as a SiP SMC function.
+   Default is 0.
+
+-  ``ARM_IO_IN_DTB``: This flag determines whether to use IO based on the
+   firmware configuration framework. This will move the io_policies into a
+   configuration device tree, instead of static structure in the code base.
+
+-  ``COT_DESC_IN_DTB``: This flag determines whether to create COT descriptors
+   at runtime using fconf. If this flag is enabled, COT descriptors are
+   statically captured in tb_fw_config file in the form of device tree nodes
+   and properties. Currently, COT descriptors used by BL2 are moved to the
+   device tree and COT descriptors used by BL1 are retained in the code
+   base statically.
+
+-  ``SDEI_IN_FCONF``: This flag determines whether to configure SDEI setup in
+   runtime using firmware configuration framework. The platform specific SDEI
+   shared and private events configuration is retrieved from device tree rather
+   than static C structures at compile time. This is only supported if
+   SDEI_SUPPORT build flag is enabled.
+
+-  ``SEC_INT_DESC_IN_FCONF``: This flag determines whether to configure Group 0
+   and Group1 secure interrupts using the firmware configuration framework. The
+   platform specific secure interrupt property descriptor is retrieved from
+   device tree in runtime rather than depending on static C structure at compile
+   time.
+
+-  ``USE_ROMLIB``: This flag determines whether library at ROM will be used.
+   This feature creates a library of functions to be placed in ROM and thus
+   reduces SRAM usage. Refer to :ref:`Library at ROM` for further details. Default
+   is 0.
+
+-  ``V``: Verbose build. If assigned anything other than 0, the build commands
+   are printed. Default is 0.
+
+-  ``VERSION_STRING``: String used in the log output for each TF-A image.
+   Defaults to a string formed by concatenating the version number, build type
+   and build string.
+
+-  ``W``: Warning level. Some compiler warning options of interest have been
+   regrouped and put in the root Makefile. This flag can take the values 0 to 3,
+   each level enabling more warning options. Default is 0.
+
+-  ``WARMBOOT_ENABLE_DCACHE_EARLY`` : Boolean option to enable D-cache early on
+   the CPU after warm boot. This is applicable for platforms which do not
+   require interconnect programming to enable cache coherency (eg: single
+   cluster platforms). If this option is enabled, then warm boot path
+   enables D-caches immediately after enabling MMU. This option defaults to 0.
+
+-  ``SUPPORT_STACK_MEMTAG``: This flag determines whether to enable memory
+   tagging for stack or not. It accepts 2 values: ``yes`` and ``no``. The
+   default value of this flag is ``no``. Note this option must be enabled only
+   for ARM architecture greater than Armv8.5-A.
+
+-  ``ERRATA_SPECULATIVE_AT``: This flag determines whether to enable ``AT``
+   speculative errata workaround or not. It accepts 2 values: ``1`` and ``0``.
+   The default value of this flag is ``0``.
+
+   ``AT`` speculative errata workaround disables stage1 page table walk for
+   lower ELs (EL1 and EL0) in EL3 so that ``AT`` speculative fetch at any point
+   produces either the correct result or failure without TLB allocation.
+
+   This boolean option enables errata for all below CPUs.
+
+   +---------+--------------+-------------------------+
+   | Errata  |      CPU     |     Workaround Define   |
+   +=========+==============+=========================+
+   | 1165522 |  Cortex-A76  |  ``ERRATA_A76_1165522`` |

+   | 1530924 |  Cortex-A53  |  ``ERRATA_A53_1530924`` |
+   +---------+--------------+-------------------------+
+
+   .. note::
+      This option is enabled by build only if platform sets any of above defines
+      mentioned in ’Workaround Define' column in the table.
+      If this option is enabled for the EL3 software then EL2 software also must
+      implement this workaround due to the behaviour of the errata mentioned
+      in new SDEN document which will get published soon.
+
+- ``RAS_TRAP_NS_ERR_REC_ACCESS``: This flag enables/disables the SCR_EL3.TERR
+  bit, to trap access to the RAS ERR and RAS ERX registers from lower ELs.
+  This flag is disabled by default.
+
+- ``OPENSSL_DIR``: This option is used to provide the path to a directory on the
+  host machine where a custom installation of OpenSSL is located, which is used
+  to build the certificate generation, firmware encryption and FIP tools. If
+  this option is not set, the default OS installation will be used.
+
+- ``USE_SP804_TIMER``: Use the SP804 timer instead of the Generic Timer for
+  functions that wait for an arbitrary time length (udelay and mdelay). The
+  default value is 0.
+
+- ``ENABLE_BRBE_FOR_NS``: Numeric value to enable access to the branch record
+  buffer registers from NS ELs when FEAT_BRBE is implemented. BRBE is an
+  optional architectural feature for AArch64. This flag can take the values
+  0 to 2, to align with the ``FEATURE_DETECTION`` mechanism. The default is 0
+  and it is automatically disabled when the target architecture is AArch32.
+
+- ``ENABLE_TRBE_FOR_NS``: Numeric value to enable access of trace buffer
+  control registers from NS ELs, NS-EL2 or NS-EL1(when NS-EL2 is implemented
+  but unused) when FEAT_TRBE is implemented. TRBE is an optional architectural
+  feature for AArch64. This flag can take the values  0 to 2, to align with the
+  ``FEATURE_DETECTION`` mechanism. The default is 0 and it is automatically
+  disabled when the target architecture is AArch32.
+
+- ``ENABLE_SYS_REG_TRACE_FOR_NS``: Boolean option to enable trace system
+  registers access from NS ELs, NS-EL2 or NS-EL1 (when NS-EL2 is implemented
+  but unused). This feature is available if trace unit such as ETMv4.x, and
+  ETE(extending ETM feature) is implemented. This flag is disabled by default.
+
+- ``ENABLE_TRF_FOR_NS``: Numeric value to enable trace filter control registers
+  access from NS ELs, NS-EL2 or NS-EL1 (when NS-EL2 is implemented but unused),
+  if FEAT_TRF is implemented. This flag can take the values 0 to 2, to align
+  with the ``FEATURE_DETECTION`` mechanism. This flag is disabled by default.
+
+- ``PLAT_RSS_NOT_SUPPORTED``: Boolean option to enable the usage of the PSA
+  APIs on platforms that doesn't support RSS (providing Arm CCA HES
+  functionalities). When enabled (``1``), a mocked version of the APIs are used.
+  The default value is 0.
+
+- ``CONDITIONAL_CMO``: Boolean option to enable call to platform-defined routine
+  ``plat_can_cmo`` which will return zero if cache management operations should
+  be skipped and non-zero otherwise. By default, this option is disabled which
+  means platform hook won't be checked and CMOs will always be performed when
+  related functions are called.
+
+GICv3 driver options
+--------------------
+
+GICv3 driver files are included using directive:
+
+``include drivers/arm/gic/v3/gicv3.mk``
+
+The driver can be configured with the following options set in the platform
+makefile:
+
+-  ``GICV3_SUPPORT_GIC600``: Add support for the GIC-600 variants of GICv3.
+   Enabling this option will add runtime detection support for the
+   GIC-600, so is safe to select even for a GIC500 implementation.
+   This option defaults to 0.
+
+- ``GICV3_SUPPORT_GIC600AE_FMU``: Add support for the Fault Management Unit
+   for GIC-600 AE. Enabling this option will introduce support to initialize
+   the FMU. Platforms should call the init function during boot to enable the
+   FMU and its safety mechanisms. This option defaults to 0.
+
+-  ``GICV3_IMPL_GIC600_MULTICHIP``: Selects GIC-600 variant with multichip
+   functionality. This option defaults to 0
+
+-  ``GICV3_OVERRIDE_DISTIF_PWR_OPS``: Allows override of default implementation
+   of ``arm_gicv3_distif_pre_save`` and ``arm_gicv3_distif_post_restore``
+   functions. This is required for FVP platform which need to simulate GIC save
+   and restore during SYSTEM_SUSPEND without powering down GIC. Default is 0.
+
+-  ``GIC_ENABLE_V4_EXTN`` : Enables GICv4 related changes in GICv3 driver.
+   This option defaults to 0.
+
+-  ``GIC_EXT_INTID``: When set to ``1``, GICv3 driver will support extended
+   PPI (1056-1119) and SPI (4096-5119) range. This option defaults to 0.
+
+Debugging options
+-----------------
+
+To compile a debug version and make the build more verbose use
+
+.. code:: shell
+
+    make PLAT=<platform> DEBUG=1 V=1 all
+
+AArch64 GCC 11 uses DWARF version 5 debugging symbols by default. Some tools
+(for example Arm-DS) might not support this and may need an older version of
+DWARF symbols to be emitted by GCC. This can be achieved by using the
+``-gdwarf-<version>`` flag, with the version being set to 2, 3, 4 or 5. Setting
+the version to 4 is recommended for Arm-DS.
+
+When debugging logic problems it might also be useful to disable all compiler
+optimizations by using ``-O0``.
+
+.. warning::
+   Using ``-O0`` could cause output images to be larger and base addresses
+   might need to be recalculated (see the **Memory layout on Arm development
+   platforms** section in the :ref:`Firmware Design`).
+
+Extra debug options can be passed to the build system by setting ``CFLAGS`` or
+``LDFLAGS``:
+
+.. code:: shell
+
+    CFLAGS='-O0 -gdwarf-2'                                     \
+    make PLAT=<platform> DEBUG=1 V=1 all
+
+Note that using ``-Wl,`` style compilation driver options in ``CFLAGS`` will be
+ignored as the linker is called directly.
+
+It is also possible to introduce an infinite loop to help in debugging the
+post-BL2 phase of TF-A. This can be done by rebuilding BL1 with the
+``SPIN_ON_BL1_EXIT=1`` build flag. Refer to the :ref:`build_options_common`
+section. In this case, the developer may take control of the target using a
+debugger when indicated by the console output. When using Arm-DS, the following
+commands can be used:
+
+::
+
+    # Stop target execution
+    interrupt
+
+    #
+    # Prepare your debugging environment, e.g. set breakpoints
+    #
+
+    # Jump over the debug loop
+    set var $AARCH64::$Core::$PC = $AARCH64::$Core::$PC + 4
+
+    # Resume execution
+    continue
+
+Firmware update options
+-----------------------
+
+-  ``NR_OF_FW_BANKS``: Define the number of firmware banks. This flag is used
+   in defining the firmware update metadata structure. This flag is by default
+   set to '2'.
+
+-  ``NR_OF_IMAGES_IN_FW_BANK``: Define the number of firmware images in each
+   firmware bank. Each firmware bank must have the same number of images as per
+   the `PSA FW update specification`_.
+   This flag is used in defining the firmware update metadata structure. This
+   flag is by default set to '1'.
+
+-  ``PSA_FWU_SUPPORT``: Enable the firmware update mechanism as per the
+   `PSA FW update specification`_. The default value is 0, and this is an
+   experimental feature.
+   PSA firmware update implementation has some limitations, such as BL2 is
+   not part of the protocol-updatable images, if BL2 needs to be updated, then
+   it should be done through another platform-defined mechanism, and it assumes
+   that the platform's hardware supports CRC32 instructions.

+Building Documentation
+======================
+
+To create a rendered copy of this documentation locally you can use the
+`Sphinx`_ tool to build and package the plain-text documents into HTML-formatted
+pages.
+
+If you are building the documentation for the first time then you will need to
+check that you have the required software packages, as described in the
+*Prerequisites* section that follows.
+
+.. note::
+   An online copy of the documentation is available at
+   https://www.trustedfirmware.org/docs/tf-a, if you want to view a rendered
+   copy without doing a local build.
+
+Prerequisites
+-------------
+
+For building a local copy of the |TF-A| documentation you will need:
+
+- Python 3 (3.5 or later)
+- PlantUML (1.2017.15 or later)
+- Python modules specified in ``docs/requirements.txt``
+
+   You can install these with ``pip3`` (the Python Package Installer) by
+   passing it the requirements file above (with ``-r``). An optional ``--user``
+   argument will install them locally, but you have to add their location to
+   $PATH (pip will emit a warning). Alternatively, they can be installed
+   globally (but will probably require root privileges).
+
+   .. note::
+      Although not necessary, it is recommended you use a virtual environment.
+      More advanced usage instructions for *pip* are beyond the scope of this
+      document but you can refer to the `pip homepage`_ for detailed guides.
+
+- Optionally, the `Dia`_ application can be installed if you need to edit
+  existing ``.dia`` diagram files, or create new ones.
+
+An example set of installation commands for Ubuntu follows, assuming that the
+working directory is ``docs``:
+
+.. code:: shell
+
+    sudo apt install python3 python3-pip plantuml [dia]
+    pip3 install [--user] -r requirements.txt
+
+.. note::
+   Several other modules will be installed as dependencies. Please review
+   the list to ensure that there will be no conflicts with other modules already
+   installed in your environment.
+
+Building rendered documentation
+-------------------------------
+
+Documents can be built into HTML-formatted pages from project root directory by
+running the following command.
+
+.. code:: shell
+
+   make doc
+
+Output from the build process will be placed in:
+
+::
+
+   docs/build/html
+
+We also support building documentation in other formats. From the ``docs``
+directory of the project, run the following command to see the supported
+formats. It is important to note that you will not get the correct result if
+the command is run from the project root directory, as that would invoke the
+top-level Makefile for |TF-A| itself.
+
+.. code:: shell
+
+   make help
+
+Building rendered documentation from a container
+------------------------------------------------
+
+There may be cases where you can not either install or upgrade required
+dependencies to generate the documents, so in this case, one way to
+create the documentation is through a docker container. The first step is
+to check if `docker`_ is installed in your host, otherwise check main docker
+page for installation instructions. Once installed, run the following script
+from project root directory
+
+.. code:: shell
+
+   docker run --rm -v $PWD:/TF sphinxdoc/sphinx \
+          bash -c 'cd /TF && \
+          pip3 install plantuml -r ./docs/requirements.txt && make doc'
+
+The above command fetches the ``sphinxdoc/sphinx`` container from `docker
+hub`_, launches the container, installs documentation requirements and finally
+creates the documentation. Once done, exit the container and output from the
+build process will be placed in:
+
+::
+
+   docs/build/html

+Image Terminology
+=================
+
+This page contains the current name, abbreviated name and purpose of the various
+images referred to in the Trusted Firmware project.
+
+Common Image Features
+---------------------
+
+- Some of the names and abbreviated names have changed to accommodate new
+  requirements. The changed names are as backward compatible as possible to
+  minimize confusion. Where applicable, the previous names are indicated. Some
+  code, documentation and build artefacts may still refer to the previous names;
+  these will inevitably take time to catch up.
+
+- The main name change is to prefix each image with the processor it corresponds
+  to (for example ``AP_``, ``SCP_``, ...). In situations where there is no
+  ambiguity (for example, within AP specific code/documentation), it is
+  permitted to omit the processor prefix (for example, just BL1 instead of
+  ``AP_BL1``).
+
+- Previously, the format for 3rd level images had 2 forms; ``BL3`` was either
+  suffixed with a dash ("-") followed by a number (for example, ``BL3-1``) or a
+  subscript number, depending on whether rich text formatting was available.
+  This was confusing and often the dash gets omitted in practice. Therefore the
+  new form is to just omit the dash and not use subscript formatting.
+
+- The names no longer contain dash ("-") characters at all. In some places (for
+  example, function names) it's not possible to use this character. All dashes
+  are either removed or replaced by underscores ("_").
+
+- The abbreviation BL stands for BootLoader. This is a historical anomaly.
+  Clearly, many of these images are not BootLoaders, they are simply firmware
+  images. However, the BL abbreviation is now widely used and is retained for
+  backwards compatibility.
+
+- The image names are not case sensitive. For example, ``bl1`` is
+  interchangeable with ``BL1``, although mixed case should be avoided.
+
+Trusted Firmware Images
+-----------------------
+
+Firmware Image Package: ``FIP``
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This is a packaging format used by TF-A to package firmware images in a single
+binary. The number and type of images that should be packed in a FIP is
+platform-specific and may include TF-A images and other firmware images
+required by the platform. For example, most platforms require a BL33 image
+which corresponds to the normal world bootloader (e.g. UEFI or U-Boot).
+
+AP Boot ROM: ``AP_BL1``
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Typically, this is the first code to execute on the AP and cannot be modified.
+Its primary purpose is to perform the minimum initialization necessary to load
+and authenticate an updateable AP firmware image into an executable RAM
+location, then hand-off control to that image.
+
+AP RAM Firmware: ``AP_BL2``
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This is the 2nd stage AP firmware. It is currently also known as the "Trusted
+Boot Firmware". Its primary purpose is to perform any additional initialization
+required to load and authenticate all 3rd level firmware images into their
+executable RAM locations, then hand-off control to the EL3 Runtime Firmware.
+
+EL3 Runtime Firmware: ``AP_BL31``
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Also known as "SoC AP firmware" or "EL3 monitor firmware". Its primary purpose
+is to handle transitions between the normal and secure world.
+
+Secure-EL1 Payload (SP): ``AP_BL32``
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Typically this is a TEE or Trusted OS, providing runtime secure services to the
+normal world. However, it may refer to a more abstract Secure-EL1 Payload (SP).
+Note that this abbreviation should only be used in systems where there is a
+single or primary image executing at Secure-EL1. In systems where there are
+potentially multiple SPs and there is no concept of a primary SP, this
+abbreviation should be avoided; use the recommended **Other AP 3rd level
+images** abbreviation instead.
+
+AP Normal World Firmware: ``AP_BL33``
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+For example, UEFI or uboot. Its primary purpose is to boot a normal world OS.
+
+Other AP 3rd level images: ``AP_BL3_XXX``
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The abbreviated names of the existing 3rd level images imply a load/execution
+ordering (for example, ``AP_BL31 -> AP_BL32 -> AP_BL33``).  Some systems may
+have additional images and/or a different load/execution ordering. The
+abbreviated names of the existing images are retained for backward compatibility
+but new 3rd level images should be suffixed with an underscore followed by text
+identifier, not a number.
+
+In systems where 3rd level images are provided by different vendors, the
+abbreviated name should identify the vendor as well as the image
+function. For example, ``AP_BL3_ARM_RAS``.
+
+Realm Monitor Management Firmware: ``RMM``
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This is the Realm-EL2 firmware. It is required if
+:ref:`Realm Management Extension (RME)` feature is enabled. If a path to RMM
+image is not provided, TF-A builds Test Realm Payload (TRP) image by default
+and uses it as the RMM image.
+
+SCP Boot ROM: ``SCP_BL1`` (previously ``BL0``)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Typically, this is the first code to execute on the SCP and cannot be modified.
+Its primary purpose is to perform the minimum initialization necessary to load
+and authenticate an updateable SCP firmware image into an executable RAM
+location, then hand-off control to that image. This may be performed in
+conjunction with other processor firmware (for example, ``AP_BL1`` and
+``AP_BL2``).
+
+This image was previously abbreviated as ``BL0`` but in some systems, the SCP
+may directly load/authenticate its own firmware. In these systems, it doesn't
+make sense to interleave the image terminology for AP and SCP; both AP and SCP
+Boot ROMs are ``BL1`` from their own point of view.
+
+SCP RAM Firmware: ``SCP_BL2`` (previously ``BL3-0``)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This is the 2nd stage SCP firmware. It is currently also known as the "SCP
+runtime firmware" but it could potentially be an intermediate firmware if the
+SCP needs to load/authenticate multiple 3rd level images in future.
+
+This image was previously abbreviated as BL3-0 but from the SCP's point of view,
+this has always been the 2nd stage firmware. The previous name is too
+AP-centric.
+
+Firmware Update (FWU) Images
+----------------------------
+
+The terminology for these images has not been widely adopted yet but they have
+to be considered in a production Trusted Board Boot solution.
+
+AP Firmware Update Boot ROM: ``AP_NS_BL1U``
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Typically, this is the first normal world code to execute on the AP during a
+firmware update operation, and cannot be modified. Its primary purpose is to
+load subsequent firmware update images from an external interface and communicate
+with ``AP_BL1`` to authenticate those images.
+
+During firmware update, there are (potentially) multiple transitions between the
+secure and normal world. The "level" of the BL image is relative to the world
+it's in so it makes sense to encode "NS" in the normal world images. The absence
+of "NS" implies a secure world image.
+
+AP Firmware Update Config: ``AP_BL2U``
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This image does the minimum necessary AP secure world configuration required to
+complete the firmware update operation. It is potentially a subset of ``AP_BL2``
+functionality.
+
+SCP Firmware Update Config: ``SCP_BL2U`` (previously ``BL2-U0``)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This image does the minimum necessary SCP secure world configuration required to
+complete the firmware update operation. It is potentially a subset of
+``SCP_BL2`` functionality.
+
+AP Firmware Updater: ``AP_NS_BL2U`` (previously ``BL3-U``)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This is the 2nd stage AP normal world firmware updater. Its primary purpose is
+to load a new set of firmware images from an external interface and write them
+into non-volatile storage.
+
+Other Processor Firmware Images
+-------------------------------
+
+Some systems may have additional processors to the AP and SCP. For example, a
+Management Control Processor (MCP). Images for these processors should follow
+the same terminology, with the processor abbreviation prefix, followed by
+underscore and the level of the firmware image.
+
+For example,
+
+MCP Boot ROM: ``MCP_BL1``
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+MCP RAM Firmware: ``MCP_BL2``
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

+Performing an Initial Build
+===========================
+
+-  Before building TF-A, the environment variable ``CROSS_COMPILE`` must point
+   to your cross compiler.
+
+   For AArch64:
+
+   .. code:: shell
+
+       export CROSS_COMPILE=<path-to-aarch64-gcc>/bin/aarch64-none-elf-
+
+   For AArch32:
+
+   .. code:: shell
+
+       export CROSS_COMPILE=<path-to-aarch32-gcc>/bin/arm-none-eabi-
+
+   It is possible to build TF-A using Clang or Arm Compiler 6. To do so
+   ``CC`` needs to point to the clang or armclang binary, which will
+   also select the clang or armclang assembler. Arm Compiler 6 will be selected
+   when the base name of the path assigned to ``CC`` matches the string
+   'armclang'. GNU binutils are required since the TF-A build system doesn't
+   currently support Arm Scatter files. Meaning the GNU linker is used by
+   default for Arm Compiler 6. Because of this dependency, ``CROSS_COMPILE``
+   should be set as described above.
+
+   For AArch64 using Arm Compiler 6:
+
+   .. code:: shell
+
+       export CROSS_COMPILE=<path-to-aarch64-gcc>/bin/aarch64-none-elf-
+       make CC=<path-to-armclang>/bin/armclang PLAT=<platform> all
+
+   On the other hand, Clang uses LLVM linker (LLD) and other LLVM binutils by
+   default instead of GNU utilities (LLVM linker (LLD) 14.0.0 is known to
+   work with TF-A). ``CROSS_COMPILE`` need not be set for Clang. Please note,
+   that the default linker may be manually overridden using the ``LD`` variable.
+
+   Clang will be selected when the base name of the path assigned to ``CC``
+   contains the string 'clang'. This is to allow both clang and clang-X.Y
+   to work.
+
+   For AArch64 using clang:
+
+   .. code:: shell
+
+       make CC=<path-to-clang>/bin/clang PLAT=<platform> all
+
+-  Change to the root directory of the TF-A source tree and build.
+
+   For AArch64:
+
+   .. code:: shell
+
+       make PLAT=<platform> all
+
+   For AArch32:
+
+   .. code:: shell
+
+       make PLAT=<platform> ARCH=aarch32 AARCH32_SP=sp_min all
+
+   Notes:
+
+   -  If ``PLAT`` is not specified, ``fvp`` is assumed by default. See the
+      :ref:`Build Options` document for more information on available build
+      options.
+
+   -  (AArch32 only) Currently only ``PLAT=fvp`` is supported.
+
+   -  (AArch32 only) ``AARCH32_SP`` is the AArch32 EL3 Runtime Software and it
+      corresponds to the BL32 image. A minimal ``AARCH32_SP``, sp_min, is
+      provided by TF-A to demonstrate how PSCI Library can be integrated with
+      an AArch32 EL3 Runtime Software. Some AArch32 EL3 Runtime Software may
+      include other runtime services, for example Trusted OS services. A guide
+      to integrate PSCI library with AArch32 EL3 Runtime Software can be found
+      at :ref:`PSCI Library Integration guide for Armv8-A AArch32 systems`.
+
+   -  (AArch64 only) The TSP (Test Secure Payload), corresponding to the BL32
+      image, is not compiled in by default. Refer to the
+      :ref:`Test Secure Payload (TSP) and Dispatcher (TSPD)` document for
+      details on building the TSP.
+
+   -  By default this produces a release version of the build. To produce a
+      debug version instead, refer to the "Debugging options" section below.
+
+   -  The build process creates products in a ``build`` directory tree, building
+      the objects and binaries for each boot loader stage in separate
+      sub-directories. The following boot loader binary files are created
+      from the corresponding ELF files:
+
+      -  ``build/<platform>/<build-type>/bl1.bin``
+      -  ``build/<platform>/<build-type>/bl2.bin``
+      -  ``build/<platform>/<build-type>/bl31.bin`` (AArch64 only)
+      -  ``build/<platform>/<build-type>/bl32.bin`` (mandatory for AArch32)
+
+      where ``<platform>`` is the name of the chosen platform and ``<build-type>``
+      is either ``debug`` or ``release``. The actual number of images might differ
+      depending on the platform.
+
+-  Build products for a specific build variant can be removed using:
+
+   .. code:: shell
+
+       make DEBUG=<D> PLAT=<platform> clean
+
+   ... where ``<D>`` is ``0`` or ``1``, as specified when building.
+
+   The build tree can be removed completely using:
+
+   .. code:: shell
+
+       make realclean

+Porting Guide
+=============
+
+Introduction
+------------
+
+Porting Trusted Firmware-A (TF-A) to a new platform involves making some
+mandatory and optional modifications for both the cold and warm boot paths.
+Modifications consist of:
+
+-  Implementing a platform-specific function or variable,
+-  Setting up the execution context in a certain way, or
+-  Defining certain constants (for example #defines).
+
+The platform-specific functions and variables are declared in
+``include/plat/common/platform.h``. The firmware provides a default
+implementation of variables and functions to fulfill the optional requirements.
+These implementations are all weakly defined; they are provided to ease the
+porting effort. Each platform port can override them with its own implementation
+if the default implementation is inadequate.
+
+Some modifications are common to all Boot Loader (BL) stages. Section 2
+discusses these in detail. The subsequent sections discuss the remaining
+modifications for each BL stage in detail.
+
+Please refer to the :ref:`Platform Ports Policy` for the policy regarding
+compatibility and deprecation of these porting interfaces.
+
+Only Arm development platforms (such as FVP and Juno) may use the
+functions/definitions in ``include/plat/arm/common/`` and the corresponding
+source files in ``plat/arm/common/``. This is done so that there are no
+dependencies between platforms maintained by different people/companies. If you
+want to use any of the functionality present in ``plat/arm`` files, please
+create a pull request that moves the code to ``plat/common`` so that it can be
+discussed.
+
+Common modifications
+--------------------
+
+This section covers the modifications that should be made by the platform for
+each BL stage to correctly port the firmware stack. They are categorized as
+either mandatory or optional.
+
+Common mandatory modifications
+------------------------------
+
+A platform port must enable the Memory Management Unit (MMU) as well as the
+instruction and data caches for each BL stage. Setting up the translation
+tables is the responsibility of the platform port because memory maps differ
+across platforms. A memory translation library (see ``lib/xlat_tables/``) is
+provided to help in this setup.
+
+Note that although this library supports non-identity mappings, this is intended
+only for re-mapping peripheral physical addresses and allows platforms with high
+I/O addresses to reduce their virtual address space. All other addresses
+corresponding to code and data must currently use an identity mapping.
+
+Also, the only translation granule size supported in TF-A is 4KB, as various
+parts of the code assume that is the case. It is not possible to switch to
+16 KB or 64 KB granule sizes at the moment.
+
+In Arm standard platforms, each BL stage configures the MMU in the
+platform-specific architecture setup function, ``blX_plat_arch_setup()``, and uses
+an identity mapping for all addresses.
+
+If the build option ``USE_COHERENT_MEM`` is enabled, each platform can allocate a
+block of identity mapped secure memory with Device-nGnRE attributes aligned to
+page boundary (4K) for each BL stage. All sections which allocate coherent
+memory are grouped under ``coherent_ram``. For ex: Bakery locks are placed in a
+section identified by name ``bakery_lock`` inside ``coherent_ram`` so that its
+possible for the firmware to place variables in it using the following C code
+directive:
+
+::
+
+    __section("bakery_lock")
+
+Or alternatively the following assembler code directive:
+
+::
+
+    .section bakery_lock
+
+The ``coherent_ram`` section is a sum of all sections like ``bakery_lock`` which are
+used to allocate any data structures that are accessed both when a CPU is
+executing with its MMU and caches enabled, and when it's running with its MMU
+and caches disabled. Examples are given below.
+
+The following variables, functions and constants must be defined by the platform
+for the firmware to work correctly.
+
+.. _platform_def_mandatory:
+
+File : platform_def.h [mandatory]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Each platform must ensure that a header file of this name is in the system
+include path with the following constants defined. This will require updating
+the list of ``PLAT_INCLUDES`` in the ``platform.mk`` file.
+
+Platform ports may optionally use the file ``include/plat/common/common_def.h``,
+which provides typical values for some of the constants below. These values are
+likely to be suitable for all platform ports.
+
+-  **#define : PLATFORM_LINKER_FORMAT**
+
+   Defines the linker format used by the platform, for example
+   ``elf64-littleaarch64``.
+
+-  **#define : PLATFORM_LINKER_ARCH**
+
+   Defines the processor architecture for the linker by the platform, for
+   example ``aarch64``.
+
+-  **#define : PLATFORM_STACK_SIZE**
+
+   Defines the normal stack memory available to each CPU. This constant is used
+   by ``plat/common/aarch64/platform_mp_stack.S`` and
+   ``plat/common/aarch64/platform_up_stack.S``.
+
+-  **#define : CACHE_WRITEBACK_GRANULE**
+
+   Defines the size in bytes of the largest cache line across all the cache
+   levels in the platform.
+
+-  **#define : FIRMWARE_WELCOME_STR**
+
+   Defines the character string printed by BL1 upon entry into the ``bl1_main()``
+   function.
+
+-  **#define : PLATFORM_CORE_COUNT**
+
+   Defines the total number of CPUs implemented by the platform across all
+   clusters in the system.
+
+-  **#define : PLAT_NUM_PWR_DOMAINS**
+
+   Defines the total number of nodes in the power domain topology
+   tree at all the power domain levels used by the platform.
+   This macro is used by the PSCI implementation to allocate
+   data structures to represent power domain topology.
+
+-  **#define : PLAT_MAX_PWR_LVL**
+
+   Defines the maximum power domain level that the power management operations
+   should apply to. More often, but not always, the power domain level
+   corresponds to affinity level. This macro allows the PSCI implementation
+   to know the highest power domain level that it should consider for power
+   management operations in the system that the platform implements. For
+   example, the Base AEM FVP implements two clusters with a configurable
+   number of CPUs and it reports the maximum power domain level as 1.
+
+-  **#define : PLAT_MAX_OFF_STATE**
+
+   Defines the local power state corresponding to the deepest power down
+   possible at every power domain level in the platform. The local power
+   states for each level may be sparsely allocated between 0 and this value
+   with 0 being reserved for the RUN state. The PSCI implementation uses this
+   value to initialize the local power states of the power domain nodes and
+   to specify the requested power state for a PSCI_CPU_OFF call.
+
+-  **#define : PLAT_MAX_RET_STATE**
+
+   Defines the local power state corresponding to the deepest retention state
+   possible at every power domain level in the platform. This macro should be
+   a value less than PLAT_MAX_OFF_STATE and greater than 0. It is used by the
+   PSCI implementation to distinguish between retention and power down local
+   power states within PSCI_CPU_SUSPEND call.
+
+-  **#define : PLAT_MAX_PWR_LVL_STATES**
+
+   Defines the maximum number of local power states per power domain level
+   that the platform supports. The default value of this macro is 2 since
+   most platforms just support a maximum of two local power states at each
+   power domain level (power-down and retention). If the platform needs to
+   account for more local power states, then it must redefine this macro.
+
+   Currently, this macro is used by the Generic PSCI implementation to size
+   the array used for PSCI_STAT_COUNT/RESIDENCY accounting.
+
+-  **#define : BL1_RO_BASE**
+
+   Defines the base address in secure ROM where BL1 originally lives. Must be
+   aligned on a page-size boundary.
+
+-  **#define : BL1_RO_LIMIT**
+
+   Defines the maximum address in secure ROM that BL1's actual content (i.e.
+   excluding any data section allocated at runtime) can occupy.
+
+-  **#define : BL1_RW_BASE**
+
+   Defines the base address in secure RAM where BL1's read-write data will live
+   at runtime. Must be aligned on a page-size boundary.
+
+-  **#define : BL1_RW_LIMIT**
+
+   Defines the maximum address in secure RAM that BL1's read-write data can
+   occupy at runtime.
+
+-  **#define : BL2_BASE**
+
+   Defines the base address in secure RAM where BL1 loads the BL2 binary image.
+   Must be aligned on a page-size boundary. This constant is not applicable
+   when BL2_IN_XIP_MEM is set to '1'.
+
+-  **#define : BL2_LIMIT**
+
+   Defines the maximum address in secure RAM that the BL2 image can occupy.
+   This constant is not applicable when BL2_IN_XIP_MEM is set to '1'.
+
+-  **#define : BL2_RO_BASE**
+
+   Defines the base address in secure XIP memory where BL2 RO section originally
+   lives. Must be aligned on a page-size boundary. This constant is only needed
+   when BL2_IN_XIP_MEM is set to '1'.
+
+-  **#define : BL2_RO_LIMIT**
+
+   Defines the maximum address in secure XIP memory that BL2's actual content
+   (i.e. excluding any data section allocated at runtime) can occupy. This
+   constant is only needed when BL2_IN_XIP_MEM is set to '1'.
+
+-  **#define : BL2_RW_BASE**
+
+   Defines the base address in secure RAM where BL2's read-write data will live
+   at runtime. Must be aligned on a page-size boundary. This constant is only
+   needed when BL2_IN_XIP_MEM is set to '1'.
+
+-  **#define : BL2_RW_LIMIT**
+
+   Defines the maximum address in secure RAM that BL2's read-write data can
+   occupy at runtime. This constant is only needed when BL2_IN_XIP_MEM is set
+   to '1'.
+
+-  **#define : BL31_BASE**
+
+   Defines the base address in secure RAM where BL2 loads the BL31 binary
+   image. Must be aligned on a page-size boundary.
+
+-  **#define : BL31_LIMIT**
+
+   Defines the maximum address in secure RAM that the BL31 image can occupy.
+
+-  **#define : PLAT_RSS_COMMS_PAYLOAD_MAX_SIZE**
+
+   Defines the maximum message size between AP and RSS. Need to define if
+   platform supports RSS.
+
+For every image, the platform must define individual identifiers that will be
+used by BL1 or BL2 to load the corresponding image into memory from non-volatile
+storage. For the sake of performance, integer numbers will be used as
+identifiers. The platform will use those identifiers to return the relevant
+information about the image to be loaded (file handler, load address,
+authentication information, etc.). The following image identifiers are
+mandatory:
+
+-  **#define : BL2_IMAGE_ID**
+
+   BL2 image identifier, used by BL1 to load BL2.
+
+-  **#define : BL31_IMAGE_ID**
+
+   BL31 image identifier, used by BL2 to load BL31.
+
+-  **#define : BL33_IMAGE_ID**
+
+   BL33 image identifier, used by BL2 to load BL33.
+
+If Trusted Board Boot is enabled, the following certificate identifiers must
+also be defined:
+
+-  **#define : TRUSTED_BOOT_FW_CERT_ID**
+
+   BL2 content certificate identifier, used by BL1 to load the BL2 content
+   certificate.
+
+-  **#define : TRUSTED_KEY_CERT_ID**
+
+   Trusted key certificate identifier, used by BL2 to load the trusted key
+   certificate.
+
+-  **#define : SOC_FW_KEY_CERT_ID**
+
+   BL31 key certificate identifier, used by BL2 to load the BL31 key
+   certificate.
+
+-  **#define : SOC_FW_CONTENT_CERT_ID**
+
+   BL31 content certificate identifier, used by BL2 to load the BL31 content
+   certificate.
+
+-  **#define : NON_TRUSTED_FW_KEY_CERT_ID**
+
+   BL33 key certificate identifier, used by BL2 to load the BL33 key
+   certificate.
+
+-  **#define : NON_TRUSTED_FW_CONTENT_CERT_ID**
+
+   BL33 content certificate identifier, used by BL2 to load the BL33 content
+   certificate.
+
+-  **#define : FWU_CERT_ID**
+
+   Firmware Update (FWU) certificate identifier, used by NS_BL1U to load the
+   FWU content certificate.
+
+-  **#define : PLAT_CRYPTOCELL_BASE**
+
+   This defines the base address of Arm® TrustZone® CryptoCell and must be
+   defined if CryptoCell crypto driver is used for Trusted Board Boot. For
+   capable Arm platforms, this driver is used if ``ARM_CRYPTOCELL_INTEG`` is
+   set.
+
+If the AP Firmware Updater Configuration image, BL2U is used, the following
+must also be defined:
+
+-  **#define : BL2U_BASE**
+
+   Defines the base address in secure memory where BL1 copies the BL2U binary
+   image. Must be aligned on a page-size boundary.
+
+-  **#define : BL2U_LIMIT**
+
+   Defines the maximum address in secure memory that the BL2U image can occupy.
+
+-  **#define : BL2U_IMAGE_ID**
+
+   BL2U image identifier, used by BL1 to fetch an image descriptor
+   corresponding to BL2U.
+
+If the SCP Firmware Update Configuration Image, SCP_BL2U is used, the following
+must also be defined:
+
+-  **#define : SCP_BL2U_IMAGE_ID**
+
+   SCP_BL2U image identifier, used by BL1 to fetch an image descriptor
+   corresponding to SCP_BL2U.
+
+   .. note::
+      TF-A does not provide source code for this image.
+
+If the Non-Secure Firmware Updater ROM, NS_BL1U is used, the following must
+also be defined:
+
+-  **#define : NS_BL1U_BASE**
+
+   Defines the base address in non-secure ROM where NS_BL1U executes.
+   Must be aligned on a page-size boundary.
+
+   .. note::
+      TF-A does not provide source code for this image.
+
+-  **#define : NS_BL1U_IMAGE_ID**
+
+   NS_BL1U image identifier, used by BL1 to fetch an image descriptor
+   corresponding to NS_BL1U.
+
+If the Non-Secure Firmware Updater, NS_BL2U is used, the following must also
+be defined:
+
+-  **#define : NS_BL2U_BASE**
+
+   Defines the base address in non-secure memory where NS_BL2U executes.
+   Must be aligned on a page-size boundary.

+   NS_BL2U image identifier, used by BL1 to fetch an image descriptor
+   corresponding to NS_BL2U.
+
+For the the Firmware update capability of TRUSTED BOARD BOOT, the following
+macros may also be defined:
+
+-  **#define : PLAT_FWU_MAX_SIMULTANEOUS_IMAGES**
+
+   Total number of images that can be loaded simultaneously. If the platform
+   doesn't specify any value, it defaults to 10.
+
+If a SCP_BL2 image is supported by the platform, the following constants must
+also be defined:
+
+-  **#define : SCP_BL2_IMAGE_ID**
+
+   SCP_BL2 image identifier, used by BL2 to load SCP_BL2 into secure memory
+   from platform storage before being transferred to the SCP.
+
+-  **#define : SCP_FW_KEY_CERT_ID**
+
+   SCP_BL2 key certificate identifier, used by BL2 to load the SCP_BL2 key
+   certificate (mandatory when Trusted Board Boot is enabled).
+
+-  **#define : SCP_FW_CONTENT_CERT_ID**
+
+   SCP_BL2 content certificate identifier, used by BL2 to load the SCP_BL2
+   content certificate (mandatory when Trusted Board Boot is enabled).
+
+If a BL32 image is supported by the platform, the following constants must
+also be defined:
+
+-  **#define : BL32_IMAGE_ID**
+
+   BL32 image identifier, used by BL2 to load BL32.
+
+-  **#define : TRUSTED_OS_FW_KEY_CERT_ID**
+
+   BL32 key certificate identifier, used by BL2 to load the BL32 key
+   certificate (mandatory when Trusted Board Boot is enabled).
+
+-  **#define : TRUSTED_OS_FW_CONTENT_CERT_ID**
+
+   BL32 content certificate identifier, used by BL2 to load the BL32 content
+   certificate (mandatory when Trusted Board Boot is enabled).
+
+-  **#define : BL32_BASE**
+
+   Defines the base address in secure memory where BL2 loads the BL32 binary
+   image. Must be aligned on a page-size boundary.
+
+-  **#define : BL32_LIMIT**
+
+   Defines the maximum address that the BL32 image can occupy.
+
+If the Test Secure-EL1 Payload (TSP) instantiation of BL32 is supported by the
+platform, the following constants must also be defined:
+
+-  **#define : TSP_SEC_MEM_BASE**
+
+   Defines the base address of the secure memory used by the TSP image on the
+   platform. This must be at the same address or below ``BL32_BASE``.
+
+-  **#define : TSP_SEC_MEM_SIZE**
+
+   Defines the size of the secure memory used by the BL32 image on the
+   platform. ``TSP_SEC_MEM_BASE`` and ``TSP_SEC_MEM_SIZE`` must fully
+   accommodate the memory required by the BL32 image, defined by ``BL32_BASE``
+   and ``BL32_LIMIT``.
+
+-  **#define : TSP_IRQ_SEC_PHY_TIMER**
+
+   Defines the ID of the secure physical generic timer interrupt used by the
+   TSP's interrupt handling code.
+
+If the platform port uses the translation table library code, the following
+constants must also be defined:
+
+-  **#define : PLAT_XLAT_TABLES_DYNAMIC**
+
+   Optional flag that can be set per-image to enable the dynamic allocation of
+   regions even when the MMU is enabled. If not defined, only static
+   functionality will be available, if defined and set to 1 it will also
+   include the dynamic functionality.
+
+-  **#define : MAX_XLAT_TABLES**
+
+   Defines the maximum number of translation tables that are allocated by the
+   translation table library code. To minimize the amount of runtime memory
+   used, choose the smallest value needed to map the required virtual addresses

+   image, ``MAX_XLAT_TABLES`` must be defined to accommodate the dynamic regions
+   as well.
+
+-  **#define : MAX_MMAP_REGIONS**
+
+   Defines the maximum number of regions that are allocated by the translation
+   table library code. A region consists of physical base address, virtual base
+   address, size and attributes (Device/Memory, RO/RW, Secure/Non-Secure), as
+   defined in the ``mmap_region_t`` structure. The platform defines the regions
+   that should be mapped. Then, the translation table library will create the
+   corresponding tables and descriptors at runtime. To minimize the amount of
+   runtime memory used, choose the smallest value needed to register the
+   required regions for each BL stage. If ``PLAT_XLAT_TABLES_DYNAMIC`` flag is
+   enabled for a BL image, ``MAX_MMAP_REGIONS`` must be defined to accommodate
+   the dynamic regions as well.
+
+-  **#define : PLAT_VIRT_ADDR_SPACE_SIZE**
+
+   Defines the total size of the virtual address space in bytes. For example,
+   for a 32 bit virtual address space, this value should be ``(1ULL << 32)``.
+
+-  **#define : PLAT_PHY_ADDR_SPACE_SIZE**
+
+   Defines the total size of the physical address space in bytes. For example,
+   for a 32 bit physical address space, this value should be ``(1ULL << 32)``.
+
+If the platform port uses the IO storage framework, the following constants
+must also be defined:
+
+-  **#define : MAX_IO_DEVICES**
+
+   Defines the maximum number of registered IO devices. Attempting to register
+   more devices than this value using ``io_register_device()`` will fail with
+   -ENOMEM.
+
+-  **#define : MAX_IO_HANDLES**
+
+   Defines the maximum number of open IO handles. Attempting to open more IO
+   entities than this value using ``io_open()`` will fail with -ENOMEM.
+
+-  **#define : MAX_IO_BLOCK_DEVICES**
+
+   Defines the maximum number of registered IO block devices. Attempting to
+   register more devices this value using ``io_dev_open()`` will fail
+   with -ENOMEM. MAX_IO_BLOCK_DEVICES should be less than MAX_IO_DEVICES.
+   With this macro, multiple block devices could be supported at the same
+   time.
+
+If the platform needs to allocate data within the per-cpu data framework in
+BL31, it should define the following macro. Currently this is only required if
+the platform decides not to use the coherent memory section by undefining the
+``USE_COHERENT_MEM`` build flag. In this case, the framework allocates the
+required memory within the the per-cpu data to minimize wastage.
+
+-  **#define : PLAT_PCPU_DATA_SIZE**
+
+   Defines the memory (in bytes) to be reserved within the per-cpu data
+   structure for use by the platform layer.
+
+The following constants are optional. They should be defined when the platform
+memory layout implies some image overlaying like in Arm standard platforms.
+
+-  **#define : BL31_PROGBITS_LIMIT**
+
+   Defines the maximum address in secure RAM that the BL31's progbits sections
+   can occupy.
+
+-  **#define : TSP_PROGBITS_LIMIT**
+
+   Defines the maximum address that the TSP's progbits sections can occupy.
+
+If the platform port uses the PL061 GPIO driver, the following constant may
+optionally be defined:
+
+-  **PLAT_PL061_MAX_GPIOS**
+   Maximum number of GPIOs required by the platform. This allows control how
+   much memory is allocated for PL061 GPIO controllers. The default value is
+
+   #. $(eval $(call add_define,PLAT_PL061_MAX_GPIOS))
+
+If the platform port uses the partition driver, the following constant may
+optionally be defined:
+
+-  **PLAT_PARTITION_MAX_ENTRIES**
+   Maximum number of partition entries required by the platform. This allows
+   control how much memory is allocated for partition entries. The default
+   value is 128.
+   For example, define the build flag in ``platform.mk``:
+   PLAT_PARTITION_MAX_ENTRIES := 12
+   $(eval $(call add_define,PLAT_PARTITION_MAX_ENTRIES))
+
+-  **PLAT_PARTITION_BLOCK_SIZE**
+   The size of partition block. It could be either 512 bytes or 4096 bytes.
+   The default value is 512.
+   For example, define the build flag in ``platform.mk``:
+   PLAT_PARTITION_BLOCK_SIZE := 4096
+   $(eval $(call add_define,PLAT_PARTITION_BLOCK_SIZE))
+
+The following constant is optional. It should be defined to override the default
+behaviour of the ``assert()`` function (for example, to save memory).
+
+-  **PLAT_LOG_LEVEL_ASSERT**
+   If ``PLAT_LOG_LEVEL_ASSERT`` is higher or equal than ``LOG_LEVEL_VERBOSE``,
+   ``assert()`` prints the name of the file, the line number and the asserted
+   expression. Else if it is higher than ``LOG_LEVEL_INFO``, it prints the file
+   name and the line number. Else if it is lower than ``LOG_LEVEL_INFO``, it
+   doesn't print anything to the console. If ``PLAT_LOG_LEVEL_ASSERT`` isn't
+   defined, it defaults to ``LOG_LEVEL``.
+
+If the platform port uses the DRTM feature, the following constants must be
+defined:
+
+-  **#define : PLAT_DRTM_EVENT_LOG_MAX_SIZE**
+
+   Maximum Event Log size used by the platform. Platform can decide the maximum
+   size of the Event Log buffer, depending upon the highest hash algorithm
+   chosen and the number of components selected to measure during the DRTM
+   execution flow.
+
+-  **#define : PLAT_DRTM_MMAP_ENTRIES**
+
+   Number of the MMAP entries used by the DRTM implementation to calculate the
+   size of address map region of the platform.
+
+File : plat_macros.S [mandatory]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Each platform must ensure a file of this name is in the system include path with
+the following macro defined. In the Arm development platforms, this file is
+found in ``plat/arm/board/<plat_name>/include/plat_macros.S``.
+
+-  **Macro : plat_crash_print_regs**
+
+   This macro allows the crash reporting routine to print relevant platform
+   registers in case of an unhandled exception in BL31. This aids in debugging
+   and this macro can be defined to be empty in case register reporting is not
+   desired.
+
+   For instance, GIC or interconnect registers may be helpful for
+   troubleshooting.
+
+Handling Reset
+--------------
+
+BL1 by default implements the reset vector where execution starts from a cold
+or warm boot. BL31 can be optionally set as a reset vector using the
+``RESET_TO_BL31`` make variable.
+
+For each CPU, the reset vector code is responsible for the following tasks:
+
+#. Distinguishing between a cold boot and a warm boot.
+
+#. In the case of a cold boot and the CPU being a secondary CPU, ensuring that
+   the CPU is placed in a platform-specific state until the primary CPU
+   performs the necessary steps to remove it from this state.
+
+#. In the case of a warm boot, ensuring that the CPU jumps to a platform-
+   specific address in the BL31 image in the same processor mode as it was
+   when released from reset.
+
+The following functions need to be implemented by the platform port to enable
+reset vector code to perform the above tasks.
+
+Function : plat_get_my_entrypoint() [mandatory when PROGRAMMABLE_RESET_ADDRESS == 0]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void
+    Return   : uintptr_t
+
+This function is called with the MMU and caches disabled
+(``SCTLR_EL3.M`` = 0 and ``SCTLR_EL3.C`` = 0). The function is responsible for
+distinguishing between a warm and cold reset for the current CPU using
+platform-specific means. If it's a warm reset, then it returns the warm
+reset entrypoint point provided to ``plat_setup_psci_ops()`` during
+BL31 initialization. If it's a cold reset then this function must return zero.
+
+This function does not follow the Procedure Call Standard used by the
+Application Binary Interface for the Arm 64-bit architecture. The caller should
+not assume that callee saved registers are preserved across a call to this
+function.
+
+This function fulfills requirement 1 and 3 listed above.
+
+Note that for platforms that support programming the reset address, it is
+expected that a CPU will start executing code directly at the right address,
+both on a cold and warm reset. In this case, there is no need to identify the
+type of reset nor to query the warm reset entrypoint. Therefore, implementing
+this function is not required on such platforms.
+
+Function : plat_secondary_cold_boot_setup() [mandatory when COLD_BOOT_SINGLE_CPU == 0]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void
+
+This function is called with the MMU and data caches disabled. It is responsible
+for placing the executing secondary CPU in a platform-specific state until the
+primary CPU performs the necessary actions to bring it out of that state and
+allow entry into the OS. This function must not return.
+
+In the Arm FVP port, when using the normal boot flow, each secondary CPU powers
+itself off. The primary CPU is responsible for powering up the secondary CPUs
+when normal world software requires them. When booting an EL3 payload instead,
+they stay powered on and are put in a holding pen until their mailbox gets
+populated.
+
+This function fulfills requirement 2 above.
+
+Note that for platforms that can't release secondary CPUs out of reset, only the
+primary CPU will execute the cold boot code. Therefore, implementing this
+function is not required on such platforms.
+
+Function : plat_is_my_cpu_primary() [mandatory when COLD_BOOT_SINGLE_CPU == 0]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void
+    Return   : unsigned int
+
+This function identifies whether the current CPU is the primary CPU or a
+secondary CPU. A return value of zero indicates that the CPU is not the
+primary CPU, while a non-zero return value indicates that the CPU is the
+primary CPU.
+
+Note that for platforms that can't release secondary CPUs out of reset, only the
+primary CPU will execute the cold boot code. Therefore, there is no need to
+distinguish between primary and secondary CPUs and implementing this function is
+not required.
+
+Function : platform_mem_init() [mandatory]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void
+    Return   : void
+
+This function is called before any access to data is made by the firmware, in
+order to carry out any essential memory initialization.
+
+Function: plat_get_rotpk_info()
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void *, void **, unsigned int *, unsigned int *
+    Return   : int
+
+This function is mandatory when Trusted Board Boot is enabled. It returns a
+pointer to the ROTPK stored in the platform (or a hash of it) and its length.
+The ROTPK must be encoded in DER format according to the following ASN.1
+structure:
+
+::
+
+    AlgorithmIdentifier  ::=  SEQUENCE  {
+        algorithm         OBJECT IDENTIFIER,
+        parameters        ANY DEFINED BY algorithm OPTIONAL
+    }
+
+    SubjectPublicKeyInfo  ::=  SEQUENCE  {
+        algorithm         AlgorithmIdentifier,
+        subjectPublicKey  BIT STRING
+    }
+
+In case the function returns a hash of the key:
+
+::
+
+    DigestInfo ::= SEQUENCE {
+        digestAlgorithm   AlgorithmIdentifier,
+        digest            OCTET STRING
+    }
+
+The function returns 0 on success. Any other value is treated as error by the
+Trusted Board Boot. The function also reports extra information related
+to the ROTPK in the flags parameter:
+
+::
+
+    ROTPK_IS_HASH      : Indicates that the ROTPK returned by the platform is a
+                         hash.
+    ROTPK_NOT_DEPLOYED : This allows the platform to skip certificate ROTPK
+                         verification while the platform ROTPK is not deployed.
+                         When this flag is set, the function does not need to
+                         return a platform ROTPK, and the authentication
+                         framework uses the ROTPK in the certificate without
+                         verifying it against the platform value. This flag
+                         must not be used in a deployed production environment.
+
+Function: plat_get_nv_ctr()
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void *, unsigned int *
+    Return   : int
+
+This function is mandatory when Trusted Board Boot is enabled. It returns the
+non-volatile counter value stored in the platform in the second argument. The
+cookie in the first argument may be used to select the counter in case the
+platform provides more than one (for example, on platforms that use the default
+TBBR CoT, the cookie will correspond to the OID values defined in
+TRUSTED_FW_NVCOUNTER_OID or NON_TRUSTED_FW_NVCOUNTER_OID).
+
+The function returns 0 on success. Any other value means the counter value could
+not be retrieved from the platform.
+
+Function: plat_set_nv_ctr()
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void *, unsigned int
+    Return   : int
+
+This function is mandatory when Trusted Board Boot is enabled. It sets a new
+counter value in the platform. The cookie in the first argument may be used to
+select the counter (as explained in plat_get_nv_ctr()). The second argument is
+the updated counter value to be written to the NV counter.
+
+The function returns 0 on success. Any other value means the counter value could
+not be updated.
+
+Function: plat_set_nv_ctr2()
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void *, const auth_img_desc_t *, unsigned int
+    Return   : int
+
+This function is optional when Trusted Board Boot is enabled. If this
+interface is defined, then ``plat_set_nv_ctr()`` need not be defined. The
+first argument passed is a cookie and is typically used to
+differentiate between a Non Trusted NV Counter and a Trusted NV
+Counter. The second argument is a pointer to an authentication image
+descriptor and may be used to decide if the counter is allowed to be
+updated or not. The third argument is the updated counter value to
+be written to the NV counter.
+
+The function returns 0 on success. Any other value means the counter value
+either could not be updated or the authentication image descriptor indicates
+that it is not allowed to be updated.
+
+Function: plat_convert_pk()
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void *, unsigned int, void **, unsigned int *
+    Return   : int
+
+This function is optional when Trusted Board Boot is enabled, and only
+used if the platform saves a hash of the ROTPK.
+First argument is the Distinguished Encoding Rules (DER) ROTPK.
+Second argument is its size.
+Third argument is used to return a pointer to a buffer, which hash should
+be the one saved in OTP.
+Fourth argument is a pointer to return its size.
+
+Most platforms save the hash of the ROTPK, but some may save slightly different
+information - e.g the hash of the ROTPK plus some related information.
+Defining this function allows to transform the ROTPK used to verify
+the signature to the buffer (a platform specific public key) which
+hash is saved in OTP.
+
+The default implementation copies the input key and length to the output without
+modification.
+
+The function returns 0 on success. Any other value means the expected
+public key buffer cannot be extracted.
+

+managed by an SMMU, otherwise returns *false*.
+
+Note -

+
+Common mandatory function modifications
+---------------------------------------
+
+The following functions are mandatory functions which need to be implemented
+by the platform port.
+
+Function : plat_my_core_pos()
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void
+    Return   : unsigned int
+
+This function returns the index of the calling CPU which is used as a
+CPU-specific linear index into blocks of memory (for example while allocating
+per-CPU stacks). This function will be invoked very early in the
+initialization sequence which mandates that this function should be
+implemented in assembly and should not rely on the availability of a C
+runtime environment. This function can clobber x0 - x8 and must preserve
+x9 - x29.
+
+This function plays a crucial role in the power domain topology framework in
+PSCI and details of this can be found in
+:ref:`PSCI Power Domain Tree Structure`.
+
+Function : plat_core_pos_by_mpidr()
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : u_register_t
+    Return   : int
+
+This function validates the ``MPIDR`` of a CPU and converts it to an index,
+which can be used as a CPU-specific linear index into blocks of memory. In
+case the ``MPIDR`` is invalid, this function returns -1. This function will only
+be invoked by BL31 after the power domain topology is initialized and can
+utilize the C runtime environment. For further details about how TF-A
+represents the power domain topology and how this relates to the linear CPU
+index, please refer :ref:`PSCI Power Domain Tree Structure`.
+
+Function : plat_get_mbedtls_heap() [when TRUSTED_BOARD_BOOT == 1]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Arguments : void **heap_addr, size_t *heap_size
+    Return    : int
+
+This function is invoked during Mbed TLS library initialisation to get a heap,
+by means of a starting address and a size. This heap will then be used
+internally by the Mbed TLS library. Hence, each BL stage that utilises Mbed TLS
+must be able to provide a heap to it.
+
+A helper function can be found in `drivers/auth/mbedtls/mbedtls_common.c` in
+which a heap is statically reserved during compile time inside every image
+(i.e. every BL stage) that utilises Mbed TLS. In this default implementation,
+the function simply returns the address and size of this "pre-allocated" heap.
+For a platform to use this default implementation, only a call to the helper
+from inside plat_get_mbedtls_heap() body is enough and nothing else is needed.
+
+However, by writting their own implementation, platforms have the potential to
+optimise memory usage. For example, on some Arm platforms, the Mbed TLS heap is
+shared between BL1 and BL2 stages and, thus, the necessary space is not reserved
+twice.
+
+On success the function should return 0 and a negative error code otherwise.
+
+Function : plat_get_enc_key_info() [when FW_ENC_STATUS == 0 or 1]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Arguments : enum fw_enc_status_t fw_enc_status, uint8_t *key,
+                size_t *key_len, unsigned int *flags, const uint8_t *img_id,
+                size_t img_id_len
+    Return    : int
+
+This function provides a symmetric key (either SSK or BSSK depending on
+fw_enc_status) which is invoked during runtime decryption of encrypted
+firmware images. `plat/common/plat_bl_common.c` provides a dummy weak
+implementation for testing purposes which must be overridden by the platform
+trying to implement a real world firmware encryption use-case.
+
+It also allows the platform to pass symmetric key identifier rather than
+actual symmetric key which is useful in cases where the crypto backend provides
+secure storage for the symmetric key. So in this case ``ENC_KEY_IS_IDENTIFIER``
+flag must be set in ``flags``.
+
+In addition to above a platform may also choose to provide an image specific
+symmetric key/identifier using img_id.
+
+On success the function should return 0 and a negative error code otherwise.
+
+Note that this API depends on ``DECRYPTION_SUPPORT`` build flag.
+
+Function : plat_fwu_set_images_source() [when PSA_FWU_SUPPORT == 1]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : const struct fwu_metadata *metadata
+    Return   : void
+
+This function is mandatory when PSA_FWU_SUPPORT is enabled.
+It provides a means to retrieve image specification (offset in
+non-volatile storage and length) of active/updated images using the passed
+FWU metadata, and update I/O policies of active/updated images using retrieved
+image specification information.
+Further I/O layer operations such as I/O open, I/O read, etc. on these
+images rely on this function call.
+
+In Arm platforms, this function is used to set an I/O policy of the FIP image,
+container of all active/updated secure and non-secure images.
+
+Function : plat_fwu_set_metadata_image_source() [when PSA_FWU_SUPPORT == 1]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : unsigned int image_id, uintptr_t *dev_handle,
+               uintptr_t *image_spec
+    Return   : int
+
+This function is mandatory when PSA_FWU_SUPPORT is enabled. It is
+responsible for setting up the platform I/O policy of the requested metadata
+image (either FWU_METADATA_IMAGE_ID or BKUP_FWU_METADATA_IMAGE_ID) that will
+be used to load this image from the platform's non-volatile storage.
+
+FWU metadata can not be always stored as a raw image in non-volatile storage
+to define its image specification (offset in non-volatile storage and length)
+statically in I/O policy.
+For example, the FWU metadata image is stored as a partition inside the GUID
+partition table image. Its specification is defined in the partition table
+that needs to be parsed dynamically.
+This function provides a means to retrieve such dynamic information to set
+the I/O policy of the FWU metadata image.
+Further I/O layer operations such as I/O open, I/O read, etc. on FWU metadata
+image relies on this function call.
+
+It returns '0' on success, otherwise a negative error value on error.
+Alongside, returns device handle and image specification from the I/O policy
+of the requested FWU metadata image.
+
+Function : plat_fwu_get_boot_idx() [when PSA_FWU_SUPPORT == 1]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void
+    Return   : uint32_t
+
+This function is mandatory when PSA_FWU_SUPPORT is enabled. It provides the
+means to retrieve the boot index value from the platform. The boot index is the
+bank from which the platform has booted the firmware images.
+
+By default, the platform will read the metadata structure and try to boot from
+the active bank. If the platform fails to boot from the active bank due to
+reasons like an Authentication failure, or on crossing a set number of watchdog
+resets while booting from the active bank, the platform can then switch to boot
+from a different bank. This function then returns the bank that the platform
+should boot its images from.
+
+Common optional modifications
+-----------------------------
+
+The following are helper functions implemented by the firmware that perform
+common platform-specific tasks. A platform may choose to override these
+definitions.
+
+Function : plat_set_my_stack()
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void
+    Return   : void
+
+This function sets the current stack pointer to the normal memory stack that
+has been allocated for the current CPU. For BL images that only require a
+stack for the primary CPU, the UP version of the function is used. The size
+of the stack allocated to each CPU is specified by the platform defined
+constant ``PLATFORM_STACK_SIZE``.
+
+Common implementations of this function for the UP and MP BL images are
+provided in ``plat/common/aarch64/platform_up_stack.S`` and
+``plat/common/aarch64/platform_mp_stack.S``
+
+Function : plat_get_my_stack()
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void
+    Return   : uintptr_t
+
+This function returns the base address of the normal memory stack that
+has been allocated for the current CPU. For BL images that only require a
+stack for the primary CPU, the UP version of the function is used. The size
+of the stack allocated to each CPU is specified by the platform defined
+constant ``PLATFORM_STACK_SIZE``.
+
+Common implementations of this function for the UP and MP BL images are
+provided in ``plat/common/aarch64/platform_up_stack.S`` and
+``plat/common/aarch64/platform_mp_stack.S``
+
+Function : plat_report_exception()
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : unsigned int
+    Return   : void
+
+A platform may need to report various information about its status when an
+exception is taken, for example the current exception level, the CPU security
+state (secure/non-secure), the exception type, and so on. This function is
+called in the following circumstances:
+
+-  In BL1, whenever an exception is taken.
+-  In BL2, whenever an exception is taken.
+
+The default implementation doesn't do anything, to avoid making assumptions
+about the way the platform displays its status information.
+
+For AArch64, this function receives the exception type as its argument.
+Possible values for exceptions types are listed in the
+``include/common/bl_common.h`` header file. Note that these constants are not
+related to any architectural exception code; they are just a TF-A convention.
+
+For AArch32, this function receives the exception mode as its argument.
+Possible values for exception modes are listed in the
+``include/lib/aarch32/arch.h`` header file.
+
+Function : plat_reset_handler()
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void
+    Return   : void
+
+A platform may need to do additional initialization after reset. This function
+allows the platform to do the platform specific initializations. Platform
+specific errata workarounds could also be implemented here. The API should
+preserve the values of callee saved registers x19 to x29.
+
+The default implementation doesn't do anything. If a platform needs to override
+the default implementation, refer to the :ref:`Firmware Design` for general
+guidelines.
+
+Function : plat_disable_acp()
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void
+    Return   : void
+
+This API allows a platform to disable the Accelerator Coherency Port (if
+present) during a cluster power down sequence. The default weak implementation
+doesn't do anything. Since this API is called during the power down sequence,
+it has restrictions for stack usage and it can use the registers x0 - x17 as
+scratch registers. It should preserve the value in x18 register as it is used
+by the caller to store the return address.
+
+Function : plat_error_handler()
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : int
+    Return   : void
+
+This API is called when the generic code encounters an error situation from
+which it cannot continue. It allows the platform to perform error reporting or
+recovery actions (for example, reset the system). This function must not return.
+
+The parameter indicates the type of error using standard codes from ``errno.h``.
+Possible errors reported by the generic code are:
+
+-  ``-EAUTH``: a certificate or image could not be authenticated (when Trusted
+   Board Boot is enabled)
+-  ``-ENOENT``: the requested image or certificate could not be found or an IO
+   error was detected
+-  ``-ENOMEM``: resources exhausted. TF-A does not use dynamic memory, so this
+   error is usually an indication of an incorrect array size
+
+The default implementation simply spins.
+
+Function : plat_panic_handler()
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void
+    Return   : void
+
+This API is called when the generic code encounters an unexpected error
+situation from which it cannot recover. This function must not return,
+and must be implemented in assembly because it may be called before the C
+environment is initialized.
+
+.. note::
+   The address from where it was called is stored in x30 (Link Register).
+   The default implementation simply spins.
+
+Function : plat_system_reset()
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void
+    Return   : void
+
+This function is used by the platform to resets the system. It can be used
+in any specific use-case where system needs to be resetted. For example,
+in case of DRTM implementation this function reset the system after
+writing the DRTM error code in the non-volatile storage. This function
+never returns. Failure in reset results in panic.
+
+Function : plat_get_bl_image_load_info()
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void
+    Return   : bl_load_info_t *
+
+This function returns pointer to the list of images that the platform has
+populated to load. This function is invoked in BL2 to load the
+BL3xx images.
+
+Function : plat_get_next_bl_params()
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void
+    Return   : bl_params_t *
+
+This function returns a pointer to the shared memory that the platform has
+kept aside to pass TF-A related information that next BL image needs. This
+function is invoked in BL2 to pass this information to the next BL
+image.
+
+Function : plat_get_stack_protector_canary()
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void
+    Return   : u_register_t
+
+This function returns a random value that is used to initialize the canary used
+when the stack protector is enabled with ENABLE_STACK_PROTECTOR. A predictable
+value will weaken the protection as the attacker could easily write the right
+value as part of the attack most of the time. Therefore, it should return a
+true random number.
+
+.. warning::
+   For the protection to be effective, the global data need to be placed at
+   a lower address than the stack bases. Failure to do so would allow an
+   attacker to overwrite the canary as part of the stack buffer overflow attack.
+
+Function : plat_flush_next_bl_params()
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void
+    Return   : void
+
+This function flushes to main memory all the image params that are passed to
+next image. This function is invoked in BL2 to flush this information
+to the next BL image.
+
+Function : plat_log_get_prefix()
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : unsigned int
+    Return   : const char *
+
+This function defines the prefix string corresponding to the `log_level` to be
+prepended to all the log output from TF-A. The `log_level` (argument) will
+correspond to one of the standard log levels defined in debug.h. The platform
+can override the common implementation to define a different prefix string for
+the log output. The implementation should be robust to future changes that
+increase the number of log levels.
+
+Function : plat_get_soc_version()
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void
+    Return   : int32_t
+
+This function returns soc version which mainly consist of below fields
+
+::
+
+    soc_version[30:24] = JEP-106 continuation code for the SiP
+    soc_version[23:16] = JEP-106 identification code with parity bit for the SiP
+    soc_version[15:0]  = Implementation defined SoC ID
+
+Function : plat_get_soc_revision()
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void
+    Return   : int32_t
+
+This function returns soc revision in below format
+
+::
+
+    soc_revision[0:30] = SOC revision of specific SOC
+
+Function : plat_is_smccc_feature_available()
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : u_register_t
+    Return   : int32_t
+
+This function returns SMC_ARCH_CALL_SUCCESS if the platform supports
+the SMCCC function specified in the argument; otherwise returns
+SMC_ARCH_CALL_NOT_SUPPORTED.
+
+Function : plat_mboot_measure_image()
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : unsigned int, image_info_t *
+    Return   : int
+
+When the MEASURED_BOOT flag is enabled:
+
+-  This function measures the given image and records its measurement using
+   the measured boot backend driver.
+-  On the Arm FVP port, this function measures the given image using its
+   passed id and information and then records that measurement in the
+   Event Log buffer.
+-  This function must return 0 on success, a signed integer error code
+   otherwise.
+
+When the MEASURED_BOOT flag is disabled, this function doesn't do anything.
+
+Function : plat_mboot_measure_critical_data()
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : unsigned int, const void *, size_t
+    Return   : int
+
+When the MEASURED_BOOT flag is enabled:
+
+-  This function measures the given critical data structure and records its
+   measurement using the measured boot backend driver.
+-  This function must return 0 on success, a signed integer error code
+   otherwise.
+
+When the MEASURED_BOOT flag is disabled, this function doesn't do anything.
+
+Function : plat_can_cmo()
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void
+    Return   : uint64_t
+
+When CONDITIONAL_CMO flag is enabled:
+
+- This function indicates whether cache management operations should be
+  performed. It returns 0 if CMOs should be skipped and non-zero
+  otherwise.
+- The function must not clobber x1, x2 and x3. It's also not safe to rely on
+  stack. Otherwise obey AAPCS.
+
+Modifications specific to a Boot Loader stage
+---------------------------------------------
+
+Boot Loader Stage 1 (BL1)
+-------------------------
+
+BL1 implements the reset vector where execution starts from after a cold or
+warm boot. For each CPU, BL1 is responsible for the following tasks:
+
+#. Handling the reset as described in section 2.2
+
+#. In the case of a cold boot and the CPU being the primary CPU, ensuring that
+   only this CPU executes the remaining BL1 code, including loading and passing
+   control to the BL2 stage.
+
+#. Identifying and starting the Firmware Update process (if required).
+
+#. Loading the BL2 image from non-volatile storage into secure memory at the
+   address specified by the platform defined constant ``BL2_BASE``.
+
+#. Populating a ``meminfo`` structure with the following information in memory,
+   accessible by BL2 immediately upon entry.
+
+   ::
+
+       meminfo.total_base = Base address of secure RAM visible to BL2
+       meminfo.total_size = Size of secure RAM visible to BL2
+
+   By default, BL1 places this ``meminfo`` structure at the end of secure
+   memory visible to BL2.
+
+   It is possible for the platform to decide where it wants to place the
+   ``meminfo`` structure for BL2 or restrict the amount of memory visible to
+   BL2 by overriding the weak default implementation of
+   ``bl1_plat_handle_post_image_load`` API.
+
+The following functions need to be implemented by the platform port to enable
+BL1 to perform the above tasks.
+
+Function : bl1_early_platform_setup() [mandatory]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void
+    Return   : void
+
+This function executes with the MMU and data caches disabled. It is only called
+by the primary CPU.
+
+On Arm standard platforms, this function:
+
+-  Enables a secure instance of SP805 to act as the Trusted Watchdog.
+
+-  Initializes a UART (PL011 console), which enables access to the ``printf``
+   family of functions in BL1.
+
+-  Enables issuing of snoop and DVM (Distributed Virtual Memory) requests to
+   the CCI slave interface corresponding to the cluster that includes the
+   primary CPU.
+
+Function : bl1_plat_arch_setup() [mandatory]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void
+    Return   : void
+
+This function performs any platform-specific and architectural setup that the
+platform requires. Platform-specific setup might include configuration of
+memory controllers and the interconnect.
+
+In Arm standard platforms, this function enables the MMU.
+
+This function helps fulfill requirement 2 above.
+
+Function : bl1_platform_setup() [mandatory]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void
+    Return   : void
+
+This function executes with the MMU and data caches enabled. It is responsible
+for performing any remaining platform-specific setup that can occur after the
+MMU and data cache have been enabled.
+
+if support for multiple boot sources is required, it initializes the boot
+sequence used by plat_try_next_boot_source().
+
+In Arm standard platforms, this function initializes the storage abstraction
+layer used to load the next bootloader image.
+
+This function helps fulfill requirement 4 above.
+
+Function : bl1_plat_sec_mem_layout() [mandatory]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void
+    Return   : meminfo *
+
+This function should only be called on the cold boot path. It executes with the
+MMU and data caches enabled. The pointer returned by this function must point to
+a ``meminfo`` structure containing the extents and availability of secure RAM for
+the BL1 stage.
+
+::
+
+    meminfo.total_base = Base address of secure RAM visible to BL1
+    meminfo.total_size = Size of secure RAM visible to BL1
+
+This information is used by BL1 to load the BL2 image in secure RAM. BL1 also
+populates a similar structure to tell BL2 the extents of memory available for
+its own use.
+
+This function helps fulfill requirements 4 and 5 above.
+
+Function : bl1_plat_prepare_exit() [optional]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : entry_point_info_t *
+    Return   : void
+
+This function is called prior to exiting BL1 in response to the
+``BL1_SMC_RUN_IMAGE`` SMC request raised by BL2. It should be used to perform
+platform specific clean up or bookkeeping operations before transferring
+control to the next image. It receives the address of the ``entry_point_info_t``
+structure passed from BL2. This function runs with MMU disabled.
+
+Function : bl1_plat_set_ep_info() [optional]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : unsigned int image_id, entry_point_info_t *ep_info
+    Return   : void
+
+This function allows platforms to override ``ep_info`` for the given ``image_id``.
+
+The default implementation just returns.
+
+Function : bl1_plat_get_next_image_id() [optional]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void
+    Return   : unsigned int
+
+This and the following function must be overridden to enable the FWU feature.
+
+BL1 calls this function after platform setup to identify the next image to be
+loaded and executed. If the platform returns ``BL2_IMAGE_ID`` then BL1 proceeds
+with the normal boot sequence, which loads and executes BL2. If the platform
+returns a different image id, BL1 assumes that Firmware Update is required.
+
+The default implementation always returns ``BL2_IMAGE_ID``. The Arm development
+platforms override this function to detect if firmware update is required, and
+if so, return the first image in the firmware update process.
+
+Function : bl1_plat_get_image_desc() [optional]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : unsigned int image_id
+    Return   : image_desc_t *
+
+BL1 calls this function to get the image descriptor information ``image_desc_t``
+for the provided ``image_id`` from the platform.
+
+The default implementation always returns a common BL2 image descriptor. Arm
+standard platforms return an image descriptor corresponding to BL2 or one of
+the firmware update images defined in the Trusted Board Boot Requirements
+specification.
+
+Function : bl1_plat_handle_pre_image_load() [optional]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : unsigned int image_id
+    Return   : int
+
+This function can be used by the platforms to update/use image information
+corresponding to ``image_id``. This function is invoked in BL1, both in cold
+boot and FWU code path, before loading the image.
+
+Function : bl1_plat_handle_post_image_load() [optional]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : unsigned int image_id
+    Return   : int
+
+This function can be used by the platforms to update/use image information
+corresponding to ``image_id``. This function is invoked in BL1, both in cold
+boot and FWU code path, after loading and authenticating the image.
+
+The default weak implementation of this function calculates the amount of
+Trusted SRAM that can be used by BL2 and allocates a ``meminfo_t``
+structure at the beginning of this free memory and populates it. The address
+of ``meminfo_t`` structure is updated in ``arg1`` of the entrypoint
+information to BL2.
+
+Function : bl1_plat_fwu_done() [optional]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : unsigned int image_id, uintptr_t image_src,
+               unsigned int image_size
+    Return   : void
+
+BL1 calls this function when the FWU process is complete. It must not return.
+The platform may override this function to take platform specific action, for
+example to initiate the normal boot flow.
+
+The default implementation spins forever.
+
+Function : bl1_plat_mem_check() [mandatory]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : uintptr_t mem_base, unsigned int mem_size,
+               unsigned int flags
+    Return   : int
+
+BL1 calls this function while handling FWU related SMCs, more specifically when
+copying or authenticating an image. Its responsibility is to ensure that the
+region of memory identified by ``mem_base`` and ``mem_size`` is mapped in BL1, and
+that this memory corresponds to either a secure or non-secure memory region as
+indicated by the security state of the ``flags`` argument.
+
+This function can safely assume that the value resulting from the addition of
+``mem_base`` and ``mem_size`` fits into a ``uintptr_t`` type variable and does not
+overflow.
+
+This function must return 0 on success, a non-null error code otherwise.
+
+The default implementation of this function asserts therefore platforms must
+override it when using the FWU feature.
+
+Function : bl1_plat_mboot_init() [optional]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void
+    Return   : void
+
+When the MEASURED_BOOT flag is enabled:
+
+-  This function is used to initialize the backend driver(s) of measured boot.
+-  On the Arm FVP port, this function is used to initialize the Event Log
+   backend driver, and also to write header information in the Event Log buffer.
+
+When the MEASURED_BOOT flag is disabled, this function doesn't do anything.
+
+Function : bl1_plat_mboot_finish() [optional]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void
+    Return   : void
+
+When the MEASURED_BOOT flag is enabled:
+
+-  This function is used to finalize the measured boot backend driver(s),
+   and also, set the information for the next bootloader component to
+   extend the measurement if needed.
+-  On the Arm FVP port, this function is used to pass the base address of
+   the Event Log buffer and its size to BL2 via tb_fw_config to extend the
+   Event Log buffer with the measurement of various images loaded by BL2.
+   It results in panic on error.
+
+When the MEASURED_BOOT flag is disabled, this function doesn't do anything.
+
+Boot Loader Stage 2 (BL2)
+-------------------------
+
+The BL2 stage is executed only by the primary CPU, which is determined in BL1
+using the ``platform_is_primary_cpu()`` function. BL1 passed control to BL2 at
+``BL2_BASE``. BL2 executes in Secure EL1 and and invokes
+``plat_get_bl_image_load_info()`` to retrieve the list of images to load from
+non-volatile storage to secure/non-secure RAM. After all the images are loaded
+then BL2 invokes ``plat_get_next_bl_params()`` to get the list of executable
+images to be passed to the next BL image.
+
+The following functions must be implemented by the platform port to enable BL2
+to perform the above tasks.
+
+Function : bl2_early_platform_setup2() [mandatory]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : u_register_t, u_register_t, u_register_t, u_register_t
+    Return   : void
+
+This function executes with the MMU and data caches disabled. It is only called
+by the primary CPU. The 4 arguments are passed by BL1 to BL2 and these arguments
+are platform specific.
+
+On Arm standard platforms, the arguments received are :
+
+    arg0 - Points to load address of FW_CONFIG
+
+    arg1 - ``meminfo`` structure populated by BL1. The platform copies
+    the contents of ``meminfo`` as it may be subsequently overwritten by BL2.
+
+On Arm standard platforms, this function also:
+
+-  Initializes a UART (PL011 console), which enables access to the ``printf``
+   family of functions in BL2.
+
+-  Initializes the storage abstraction layer used to load further bootloader
+   images. It is necessary to do this early on platforms with a SCP_BL2 image,
+   since the later ``bl2_platform_setup`` must be done after SCP_BL2 is loaded.
+
+Function : bl2_plat_arch_setup() [mandatory]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+

+
+Boot Loader Stage 2 (BL2) at EL3
+--------------------------------
+
+When the platform has a non-TF-A Boot ROM it is desirable to jump
+directly to BL2 instead of TF-A BL1. In this case BL2 is expected to
+execute at EL3 instead of executing at EL1. Refer to the :ref:`Firmware Design`
+document for more information.
+
+All mandatory functions of BL2 must be implemented, except the functions
+bl2_early_platform_setup and bl2_el3_plat_arch_setup, because
+their work is done now by bl2_el3_early_platform_setup and
+bl2_el3_plat_arch_setup. These functions should generally implement
+the bl1_plat_xxx() and bl2_plat_xxx() functionality combined.
+
+
+Function : bl2_el3_early_platform_setup() [mandatory]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+	Argument : u_register_t, u_register_t, u_register_t, u_register_t
+	Return   : void
+
+This function executes with the MMU and data caches disabled. It is only called
+by the primary CPU. This function receives four parameters which can be used
+by the platform to pass any needed information from the Boot ROM to BL2.
+
+On Arm standard platforms, this function does the following:
+
+-  Initializes a UART (PL011 console), which enables access to the ``printf``
+   family of functions in BL2.
+
+-  Initializes the storage abstraction layer used to load further bootloader
+   images. It is necessary to do this early on platforms with a SCP_BL2 image,
+   since the later ``bl2_platform_setup`` must be done after SCP_BL2 is loaded.
+
+- Initializes the private variables that define the memory layout used.
+
+Function : bl2_el3_plat_arch_setup() [mandatory]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+	Argument : void
+	Return   : void
+
+This function executes with the MMU and data caches disabled. It is only called
+by the primary CPU.
+
+The purpose of this function is to perform any architectural initialization
+that varies across platforms.
+
+On Arm standard platforms, this function enables the MMU.
+
+Function : bl2_el3_plat_prepare_exit() [optional]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+	Argument : void
+	Return   : void
+
+This function is called prior to exiting BL2 and run the next image.
+It should be used to perform platform specific clean up or bookkeeping
+operations before transferring control to the next image. This function
+runs with MMU disabled.
+
+FWU Boot Loader Stage 2 (BL2U)
+------------------------------
+
+The AP Firmware Updater Configuration, BL2U, is an optional part of the FWU
+process and is executed only by the primary CPU. BL1 passes control to BL2U at
+``BL2U_BASE``. BL2U executes in Secure-EL1 and is responsible for:
+
+#. (Optional) Transferring the optional SCP_BL2U binary image from AP secure
+   memory to SCP RAM. BL2U uses the SCP_BL2U ``image_info`` passed by BL1.
+   ``SCP_BL2U_BASE`` defines the address in AP secure memory where SCP_BL2U
+   should be copied from. Subsequent handling of the SCP_BL2U image is
+   implemented by the platform specific ``bl2u_plat_handle_scp_bl2u()`` function.
+   If ``SCP_BL2U_BASE`` is not defined then this step is not performed.
+
+#. Any platform specific setup required to perform the FWU process. For
+   example, Arm standard platforms initialize the TZC controller so that the
+   normal world can access DDR memory.
+
+The following functions must be implemented by the platform port to enable
+BL2U to perform the tasks mentioned above.
+
+Function : bl2u_early_platform_setup() [mandatory]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : meminfo *mem_info, void *plat_info
+    Return   : void
+
+This function executes with the MMU and data caches disabled. It is only
+called by the primary CPU. The arguments to this function is the address
+of the ``meminfo`` structure and platform specific info provided by BL1.
+
+The platform may copy the contents of the ``mem_info`` and ``plat_info`` into
+private storage as the original memory may be subsequently overwritten by BL2U.
+
+On Arm CSS platforms ``plat_info`` is interpreted as an ``image_info_t`` structure,
+to extract SCP_BL2U image information, which is then copied into a private
+variable.
+
+Function : bl2u_plat_arch_setup() [mandatory]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void
+    Return   : void
+
+This function executes with the MMU and data caches disabled. It is only
+called by the primary CPU.
+
+The purpose of this function is to perform any architectural initialization
+that varies across platforms, for example enabling the MMU (since the memory
+map differs across platforms).
+
+Function : bl2u_platform_setup() [mandatory]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void
+    Return   : void
+
+This function may execute with the MMU and data caches enabled if the platform
+port does the necessary initialization in ``bl2u_plat_arch_setup()``. It is only
+called by the primary CPU.
+
+The purpose of this function is to perform any platform initialization
+specific to BL2U.
+
+In Arm standard platforms, this function performs security setup, including
+configuration of the TrustZone controller to allow non-secure masters access
+to most of DRAM. Part of DRAM is reserved for secure world use.
+
+Function : bl2u_plat_handle_scp_bl2u() [optional]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void
+    Return   : int
+
+This function is used to perform any platform-specific actions required to
+handle the SCP firmware. Typically it transfers the image into SCP memory using
+a platform-specific protocol and waits until SCP executes it and signals to the
+Application Processor (AP) for BL2U execution to continue.
+
+This function returns 0 on success, a negative error code otherwise.
+This function is included if SCP_BL2U_BASE is defined.
+
+Boot Loader Stage 3-1 (BL31)
+----------------------------
+
+During cold boot, the BL31 stage is executed only by the primary CPU. This is
+determined in BL1 using the ``platform_is_primary_cpu()`` function. BL1 passes
+control to BL31 at ``BL31_BASE``. During warm boot, BL31 is executed by all
+CPUs. BL31 executes at EL3 and is responsible for:
+
+#. Re-initializing all architectural and platform state. Although BL1 performs
+   some of this initialization, BL31 remains resident in EL3 and must ensure
+   that EL3 architectural and platform state is completely initialized. It
+   should make no assumptions about the system state when it receives control.
+
+#. Passing control to a normal world BL image, pre-loaded at a platform-
+   specific address by BL2. On ARM platforms, BL31 uses the ``bl_params`` list
+   populated by BL2 in memory to do this.
+
+#. Providing runtime firmware services. Currently, BL31 only implements a
+   subset of the Power State Coordination Interface (PSCI) API as a runtime
+   service. See Section 3.3 below for details of porting the PSCI
+   implementation.
+
+#. Optionally passing control to the BL32 image, pre-loaded at a platform-
+   specific address by BL2. BL31 exports a set of APIs that allow runtime
+   services to specify the security state in which the next image should be
+   executed and run the corresponding image. On ARM platforms, BL31 uses the
+   ``bl_params`` list populated by BL2 in memory to do this.
+
+If BL31 is a reset vector, It also needs to handle the reset as specified in
+section 2.2 before the tasks described above.
+
+The following functions must be implemented by the platform port to enable BL31
+to perform the above tasks.
+
+Function : bl31_early_platform_setup2() [mandatory]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : u_register_t, u_register_t, u_register_t, u_register_t
+    Return   : void
+
+This function executes with the MMU and data caches disabled. It is only called
+by the primary CPU. BL2 can pass 4 arguments to BL31 and these arguments are
+platform specific.
+
+In Arm standard platforms, the arguments received are :
+
+    arg0 - The pointer to the head of `bl_params_t` list
+    which is list of executable images following BL31,
+
+    arg1 - Points to load address of SOC_FW_CONFIG if present
+           except in case of Arm FVP and Juno platform.
+
+           In case of Arm FVP and Juno platform, points to load address
+           of FW_CONFIG.
+
+    arg2 - Points to load address of HW_CONFIG if present
+
+    arg3 - A special value to verify platform parameters from BL2 to BL31. Not
+    used in release builds.
+
+The function runs through the `bl_param_t` list and extracts the entry point
+information for BL32 and BL33. It also performs the following:
+
+-  Initialize a UART (PL011 console), which enables access to the ``printf``
+   family of functions in BL31.
+
+-  Enable issuing of snoop and DVM (Distributed Virtual Memory) requests to the
+   CCI slave interface corresponding to the cluster that includes the primary
+   CPU.

+that varies across platforms.
+
+On Arm standard platforms, this function enables the MMU.
+
+Function : bl31_platform_setup() [mandatory]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void
+    Return   : void
+
+This function may execute with the MMU and data caches enabled if the platform
+port does the necessary initialization in ``bl31_plat_arch_setup()``. It is only
+called by the primary CPU.
+
+The purpose of this function is to complete platform initialization so that both
+BL31 runtime services and normal world software can function correctly.
+
+On Arm standard platforms, this function does the following:
+
+-  Initialize the generic interrupt controller.
+
+   Depending on the GIC driver selected by the platform, the appropriate GICv2
+   or GICv3 initialization will be done, which mainly consists of:
+
+   -  Enable secure interrupts in the GIC CPU interface.
+   -  Disable the legacy interrupt bypass mechanism.
+   -  Configure the priority mask register to allow interrupts of all priorities
+      to be signaled to the CPU interface.
+   -  Mark SGIs 8-15 and the other secure interrupts on the platform as secure.
+   -  Target all secure SPIs to CPU0.
+   -  Enable these secure interrupts in the GIC distributor.
+   -  Configure all other interrupts as non-secure.
+   -  Enable signaling of secure interrupts in the GIC distributor.
+
+-  Enable system-level implementation of the generic timer counter through the
+   memory mapped interface.
+
+-  Grant access to the system counter timer module
+
+-  Initialize the power controller device.
+
+   In particular, initialise the locks that prevent concurrent accesses to the

+
+Function : bl31_plat_runtime_setup() [optional]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void
+    Return   : void
+
+The purpose of this function is allow the platform to perform any BL31 runtime

+    Return   : entry_point_info *
+
+This function may execute with the MMU and data caches enabled if the platform
+port does the necessary initializations in ``bl31_plat_arch_setup()``.
+
+This function is called by ``bl31_main()`` to retrieve information provided by
+BL2 for the next image in the security state specified by the argument. BL31
+uses this information to pass control to that image in the specified security
+state. This function must return a pointer to the ``entry_point_info`` structure
+(that was copied during ``bl31_early_platform_setup()``) if the image exists. It
+should return NULL otherwise.

+This function returns the Platform attestation token.
+
+The parameters of the function are:
+

+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : uintptr_t, size_t *, unsigned int
+    Return   : int
+
+This function returns the delegated realm attestation key which will be used to
+sign Realm attestation token. The API currently only supports P-384 ECC curve
+key.
+
+The parameters of the function are:
+
+    arg0 - A pointer to the buffer where the attestation key should be copied

+    Return    : int
+
+When ENABLE_RME is enabled, this function populates a boot manifest for the

+
+Function : bl31_plat_enable_mmu [optional]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : uint32_t
+    Return   : void
+
+This function enables the MMU. The boot code calls this function with MMU and
+caches disabled. This function should program necessary registers to enable
+translation, and upon return, the MMU on the calling PE must be enabled.
+
+The function must honor flags passed in the first argument. These flags are
+defined by the translation library, and can be found in the file
+``include/lib/xlat_tables/xlat_mmu_helpers.h``.

+Function : plat_get_syscnt_freq2() [mandatory]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void
+    Return   : unsigned int
+
+This function is used by the architecture setup code to retrieve the counter
+frequency for the CPU's generic timer. This value will be programmed into the
+``CNTFRQ_EL0`` register. In Arm standard platforms, it returns the base frequency
+of the system counter, which is retrieved from the first entry in the frequency
+modes table.
+
+#define : PLAT_PERCPU_BAKERY_LOCK_SIZE [optional]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+When ``USE_COHERENT_MEM = 0``, this constant defines the total memory (in
+bytes) aligned to the cache line boundary that should be allocated per-cpu to
+accommodate all the bakery locks.
+
+If this constant is not defined when ``USE_COHERENT_MEM = 0``, the linker
+calculates the size of the ``bakery_lock`` input section, aligns it to the
+nearest ``CACHE_WRITEBACK_GRANULE``, multiplies it with ``PLATFORM_CORE_COUNT``
+and stores the result in a linker symbol. This constant prevents a platform
+from relying on the linker and provide a more efficient mechanism for
+accessing per-cpu bakery lock information.
+
+If this constant is defined and its value is not equal to the value
+calculated by the linker then a link time assertion is raised. A compile time
+assertion is raised if the value of the constant is not aligned to the cache
+line boundary.
+
+.. _porting_guide_sdei_requirements:
+
+SDEI porting requirements
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The |SDEI| dispatcher requires the platform to provide the following macros
+and functions, of which some are optional, and some others mandatory.
+
+Macros
+......
+
+Macro: PLAT_SDEI_NORMAL_PRI [mandatory]
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+This macro must be defined to the EL3 exception priority level associated with
+Normal |SDEI| events on the platform. This must have a higher value
+(therefore of lower priority) than ``PLAT_SDEI_CRITICAL_PRI``.
+
+Macro: PLAT_SDEI_CRITICAL_PRI [mandatory]
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+This macro must be defined to the EL3 exception priority level associated with
+Critical |SDEI| events on the platform. This must have a lower value
+(therefore of higher priority) than ``PLAT_SDEI_NORMAL_PRI``.
+
+**Note**: |SDEI| exception priorities must be the lowest among Secure
+priorities. Among the |SDEI| exceptions, Critical |SDEI| priority must
+be higher than Normal |SDEI| priority.
+
+Functions
+.........
+
+Function: int plat_sdei_validate_entry_point() [optional]
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+::
+
+  Argument: uintptr_t ep, unsigned int client_mode
+  Return: int
+
+This function validates the entry point address of the event handler provided by
+the client for both event registration and *Complete and Resume* |SDEI| calls.
+The function ensures that the address is valid in the client translation regime.
+
+The second argument is the exception level that the client is executing in. It
+can be Non-Secure EL1 or Non-Secure EL2.
+
+The function must return ``0`` for successful validation, or ``-1`` upon failure.
+
+The default implementation always returns ``0``. On Arm platforms, this function
+translates the entry point address within the client translation regime and
+further ensures that the resulting physical address is located in Non-secure
+DRAM.
+
+Function: void plat_sdei_handle_masked_trigger(uint64_t mpidr, unsigned int intr) [optional]
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+::
+
+  Argument: uint64_t
+  Argument: unsigned int
+  Return: void
+
+|SDEI| specification requires that a PE comes out of reset with the events
+masked. The client therefore is expected to call ``PE_UNMASK`` to unmask
+|SDEI| events on the PE. No |SDEI| events can be dispatched until such
+time.
+
+Should a PE receive an interrupt that was bound to an |SDEI| event while the
+events are masked on the PE, the dispatcher implementation invokes the function
+``plat_sdei_handle_masked_trigger``. The MPIDR of the PE that received the
+interrupt and the interrupt ID are passed as parameters.
+
+The default implementation only prints out a warning message.
+
+.. _porting_guide_trng_requirements:
+
+TRNG porting requirements
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The |TRNG| backend requires the platform to provide the following values
+and mandatory functions.
+
+Values
+......
+
+value: uuid_t plat_trng_uuid [mandatory]
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+This value must be defined to the UUID of the TRNG backend that is specific to
+the hardware after ``plat_entropy_setup`` function is called. This value must
+conform to the SMCCC calling convention; The most significant 32 bits of the
+UUID must not equal ``0xffffffff`` or the signed integer ``-1`` as this value in
+w0 indicates failure to get a TRNG source.
+
+Functions
+.........
+
+Function: void plat_entropy_setup(void) [mandatory]
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+::
+
+  Argument: none
+  Return: none
+
+This function is expected to do platform-specific initialization of any TRNG
+hardware. This may include generating a UUID from a hardware-specific seed.
+
+Function: bool plat_get_entropy(uint64_t \*out) [mandatory]
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+::
+
+  Argument: uint64_t *
+  Return: bool
+  Out : when the return value is true, the entropy has been written into the
+  storage pointed to
+
+This function writes entropy into storage provided by the caller. If no entropy
+is available, it must return false and the storage must not be written.
+
+Power State Coordination Interface (in BL31)
+--------------------------------------------
+
+The TF-A implementation of the PSCI API is based around the concept of a
+*power domain*. A *power domain* is a CPU or a logical group of CPUs which
+share some state on which power management operations can be performed as
+specified by `PSCI`_. Each CPU in the system is assigned a cpu index which is
+a unique number between ``0`` and ``PLATFORM_CORE_COUNT - 1``. The
+*power domains* are arranged in a hierarchical tree structure and each
+*power domain* can be identified in a system by the cpu index of any CPU that
+is part of that domain and a *power domain level*. A processing element (for
+example, a CPU) is at level 0. If the *power domain* node above a CPU is a
+logical grouping of CPUs that share some state, then level 1 is that group of
+CPUs (for example, a cluster), and level 2 is a group of clusters (for
+example, the system). More details on the power domain topology and its
+organization can be found in :ref:`PSCI Power Domain Tree Structure`.
+
+BL31's platform initialization code exports a pointer to the platform-specific
+power management operations required for the PSCI implementation to function
+correctly. This information is populated in the ``plat_psci_ops`` structure. The
+PSCI implementation calls members of the ``plat_psci_ops`` structure for performing
+power management operations on the power domains. For example, the target
+CPU is specified by its ``MPIDR`` in a PSCI ``CPU_ON`` call. The ``pwr_domain_on()``
+handler (if present) is called for the CPU power domain.
+
+The ``power-state`` parameter of a PSCI ``CPU_SUSPEND`` call can be used to
+describe composite power states specific to a platform. The PSCI implementation
+defines a generic representation of the power-state parameter, which is an
+array of local power states where each index corresponds to a power domain
+level. Each entry contains the local power state the power domain at that power
+level could enter. It depends on the ``validate_power_state()`` handler to
+convert the power-state parameter (possibly encoding a composite power state)
+passed in a PSCI ``CPU_SUSPEND`` call to this representation.
+
+The following functions form part of platform port of PSCI functionality.
+
+Function : plat_psci_stat_accounting_start() [optional]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : const psci_power_state_t *
+    Return   : void
+
+This is an optional hook that platforms can implement for residency statistics
+accounting before entering a low power state. The ``pwr_domain_state`` field of
+``state_info`` (first argument) can be inspected if stat accounting is done
+differently at CPU level versus higher levels. As an example, if the element at
+index 0 (CPU power level) in the ``pwr_domain_state`` array indicates a power down
+state, special hardware logic may be programmed in order to keep track of the
+residency statistics. For higher levels (array indices > 0), the residency
+statistics could be tracked in software using PMF. If ``ENABLE_PMF`` is set, the
+default implementation will use PMF to capture timestamps.
+
+Function : plat_psci_stat_accounting_stop() [optional]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : const psci_power_state_t *
+    Return   : void
+
+This is an optional hook that platforms can implement for residency statistics
+accounting after exiting from a low power state. The ``pwr_domain_state`` field
+of ``state_info`` (first argument) can be inspected if stat accounting is done
+differently at CPU level versus higher levels. As an example, if the element at
+index 0 (CPU power level) in the ``pwr_domain_state`` array indicates a power down
+state, special hardware logic may be programmed in order to keep track of the
+residency statistics. For higher levels (array indices > 0), the residency
+statistics could be tracked in software using PMF. If ``ENABLE_PMF`` is set, the
+default implementation will use PMF to capture timestamps.
+
+Function : plat_psci_stat_get_residency() [optional]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : unsigned int, const psci_power_state_t *, unsigned int
+    Return   : u_register_t
+
+This is an optional interface that is is invoked after resuming from a low power
+state and provides the time spent resident in that low power state by the power
+domain at a particular power domain level. When a CPU wakes up from suspend,
+all its parent power domain levels are also woken up. The generic PSCI code
+invokes this function for each parent power domain that is resumed and it
+identified by the ``lvl`` (first argument) parameter. The ``state_info`` (second
+argument) describes the low power state that the power domain has resumed from.
+The current CPU is the first CPU in the power domain to resume from the low
+power state and the ``last_cpu_idx`` (third parameter) is the index of the last
+CPU in the power domain to suspend and may be needed to calculate the residency
+for that power domain.
+
+Function : plat_get_target_pwr_state() [optional]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : unsigned int, const plat_local_state_t *, unsigned int
+    Return   : plat_local_state_t
+
+The PSCI generic code uses this function to let the platform participate in
+state coordination during a power management operation. The function is passed
+a pointer to an array of platform specific local power state ``states`` (second
+argument) which contains the requested power state for each CPU at a particular
+power domain level ``lvl`` (first argument) within the power domain. The function
+is expected to traverse this array of upto ``ncpus`` (third argument) and return
+a coordinated target power state by the comparing all the requested power
+states. The target power state should not be deeper than any of the requested
+power states.
+
+A weak definition of this API is provided by default wherein it assumes
+that the platform assigns a local state value in order of increasing depth
+of the power state i.e. for two power states X & Y, if X < Y
+then X represents a shallower power state than Y. As a result, the
+coordinated target local power state for a power domain will be the minimum
+of the requested local power state values.
+
+Function : plat_get_power_domain_tree_desc() [mandatory]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void
+    Return   : const unsigned char *
+
+This function returns a pointer to the byte array containing the power domain
+topology tree description. The format and method to construct this array are
+described in :ref:`PSCI Power Domain Tree Structure`. The BL31 PSCI
+initialization code requires this array to be described by the platform, either
+statically or dynamically, to initialize the power domain topology tree. In case
+the array is populated dynamically, then plat_core_pos_by_mpidr() and
+plat_my_core_pos() should also be implemented suitably so that the topology tree
+description matches the CPU indices returned by these APIs. These APIs together
+form the platform interface for the PSCI topology framework.
+
+Function : plat_setup_psci_ops() [mandatory]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : uintptr_t, const plat_psci_ops **
+    Return   : int
+
+This function may execute with the MMU and data caches enabled if the platform
+port does the necessary initializations in ``bl31_plat_arch_setup()``. It is only
+called by the primary CPU.
+
+This function is called by PSCI initialization code. Its purpose is to let
+the platform layer know about the warm boot entrypoint through the
+``sec_entrypoint`` (first argument) and to export handler routines for
+platform-specific psci power management actions by populating the passed
+pointer with a pointer to BL31's private ``plat_psci_ops`` structure.
+
+A description of each member of this structure is given below. Please refer to
+the Arm FVP specific implementation of these handlers in
+``plat/arm/board/fvp/fvp_pm.c`` as an example. For each PSCI function that the
+platform wants to support, the associated operation or operations in this
+structure must be provided and implemented (Refer section 4 of
+:ref:`Firmware Design` for the PSCI API supported in TF-A). To disable a PSCI
+function in a platform port, the operation should be removed from this
+structure instead of providing an empty implementation.
+
+plat_psci_ops.cpu_standby()
+...........................
+
+Perform the platform-specific actions to enter the standby state for a cpu
+indicated by the passed argument. This provides a fast path for CPU standby
+wherein overheads of PSCI state management and lock acquisition is avoided.
+For this handler to be invoked by the PSCI ``CPU_SUSPEND`` API implementation,
+the suspend state type specified in the ``power-state`` parameter should be
+STANDBY and the target power domain level specified should be the CPU. The
+handler should put the CPU into a low power retention state (usually by
+issuing a wfi instruction) and ensure that it can be woken up from that
+state by a normal interrupt. The generic code expects the handler to succeed.
+
+plat_psci_ops.pwr_domain_on()
+.............................
+
+Perform the platform specific actions to power on a CPU, specified
+by the ``MPIDR`` (first argument). The generic code expects the platform to
+return PSCI_E_SUCCESS on success or PSCI_E_INTERN_FAIL for any failure.
+
+plat_psci_ops.pwr_domain_off()
+..............................
+
+Perform the platform specific actions to prepare to power off the calling CPU
+and its higher parent power domain levels as indicated by the ``target_state``
+(first argument). It is called by the PSCI ``CPU_OFF`` API implementation.
+
+The ``target_state`` encodes the platform coordinated target local power states
+for the CPU power domain and its parent power domain levels. The handler
+needs to perform power management operation corresponding to the local state
+at each power level.
+
+For this handler, the local power state for the CPU power domain will be a
+power down state where as it could be either power down, retention or run state
+for the higher power domain levels depending on the result of state
+coordination. The generic code expects the handler to succeed.
+
+plat_psci_ops.pwr_domain_suspend_pwrdown_early() [optional]
+...........................................................
+
+This optional function may be used as a performance optimization to replace
+or complement pwr_domain_suspend() on some platforms. Its calling semantics
+are identical to pwr_domain_suspend(), except the PSCI implementation only
+calls this function when suspending to a power down state, and it guarantees
+that data caches are enabled.
+
+When HW_ASSISTED_COHERENCY = 0, the PSCI implementation disables data caches
+before calling pwr_domain_suspend(). If the target_state corresponds to a
+power down state and it is safe to perform some or all of the platform
+specific actions in that function with data caches enabled, it may be more
+efficient to move those actions to this function. When HW_ASSISTED_COHERENCY
+= 1, data caches remain enabled throughout, and so there is no advantage to
+moving platform specific actions to this function.
+
+plat_psci_ops.pwr_domain_suspend()
+..................................
+
+Perform the platform specific actions to prepare to suspend the calling
+CPU and its higher parent power domain levels as indicated by the
+``target_state`` (first argument). It is called by the PSCI ``CPU_SUSPEND``
+API implementation.
+
+The ``target_state`` has a similar meaning as described in
+the ``pwr_domain_off()`` operation. It encodes the platform coordinated
+target local power states for the CPU power domain and its parent
+power domain levels. The handler needs to perform power management operation
+corresponding to the local state at each power level. The generic code
+expects the handler to succeed.
+
+The difference between turning a power domain off versus suspending it is that
+in the former case, the power domain is expected to re-initialize its state
+when it is next powered on (see ``pwr_domain_on_finish()``). In the latter
+case, the power domain is expected to save enough state so that it can resume
+execution by restoring this state when its powered on (see
+``pwr_domain_suspend_finish()``).
+
+When suspending a core, the platform can also choose to power off the GICv3
+Redistributor and ITS through an implementation-defined sequence. To achieve
+this safely, the ITS context must be saved first. The architectural part is
+implemented by the ``gicv3_its_save_disable()`` helper, but most of the needed
+sequence is implementation defined and it is therefore the responsibility of
+the platform code to implement the necessary sequence. Then the GIC
+Redistributor context can be saved using the ``gicv3_rdistif_save()`` helper.
+Powering off the Redistributor requires the implementation to support it and it
+is the responsibility of the platform code to execute the right implementation
+defined sequence.
+
+When a system suspend is requested, the platform can also make use of the
+``gicv3_distif_save()`` helper to save the context of the GIC Distributor after
+it has saved the context of the Redistributors and ITS of all the cores in the
+system. The context of the Distributor can be large and may require it to be
+allocated in a special area if it cannot fit in the platform's global static
+data, for example in DRAM. The Distributor can then be powered down using an
+implementation-defined sequence.
+
+plat_psci_ops.pwr_domain_pwr_down_wfi()
+.......................................
+
+This is an optional function and, if implemented, is expected to perform
+platform specific actions including the ``wfi`` invocation which allows the
+CPU to powerdown. Since this function is invoked outside the PSCI locks,
+the actions performed in this hook must be local to the CPU or the platform
+must ensure that races between multiple CPUs cannot occur.
+
+The ``target_state`` has a similar meaning as described in the ``pwr_domain_off()``
+operation and it encodes the platform coordinated target local power states for
+the CPU power domain and its parent power domain levels. This function must
+not return back to the caller (by calling wfi in an infinite loop to ensure
+some CPUs power down mitigations work properly).
+
+If this function is not implemented by the platform, PSCI generic
+implementation invokes ``psci_power_down_wfi()`` for power down.
+
+plat_psci_ops.pwr_domain_on_finish()
+....................................
+
+This function is called by the PSCI implementation after the calling CPU is
+powered on and released from reset in response to an earlier PSCI ``CPU_ON`` call.
+It performs the platform-specific setup required to initialize enough state for
+this CPU to enter the normal world and also provide secure runtime firmware
+services.
+
+The ``target_state`` (first argument) is the prior state of the power domains
+immediately before the CPU was turned on. It indicates which power domains
+above the CPU might require initialization due to having previously been in
+low power states. The generic code expects the handler to succeed.
+
+plat_psci_ops.pwr_domain_on_finish_late() [optional]
+...........................................................
+
+This optional function is called by the PSCI implementation after the calling
+CPU is fully powered on with respective data caches enabled. The calling CPU and
+the associated cluster are guaranteed to be participating in coherency. This
+function gives the flexibility to perform any platform-specific actions safely,
+such as initialization or modification of shared data structures, without the
+overhead of explicit cache maintainace operations.
+
+The ``target_state`` has a similar meaning as described in the ``pwr_domain_on_finish()``
+operation. The generic code expects the handler to succeed.
+
+plat_psci_ops.pwr_domain_suspend_finish()
+.........................................
+
+This function is called by the PSCI implementation after the calling CPU is
+powered on and released from reset in response to an asynchronous wakeup
+event, for example a timer interrupt that was programmed by the CPU during the
+``CPU_SUSPEND`` call or ``SYSTEM_SUSPEND`` call. It performs the platform-specific
+setup required to restore the saved state for this CPU to resume execution
+in the normal world and also provide secure runtime firmware services.
+
+The ``target_state`` (first argument) has a similar meaning as described in
+the ``pwr_domain_on_finish()`` operation. The generic code expects the platform
+to succeed.
+
+If the Distributor, Redistributors or ITS have been powered off as part of a
+suspend, their context must be restored in this function in the reverse order
+to how they were saved during suspend sequence.
+
+plat_psci_ops.system_off()
+..........................
+
+This function is called by PSCI implementation in response to a ``SYSTEM_OFF``
+call. It performs the platform-specific system poweroff sequence after
+notifying the Secure Payload Dispatcher.
+
+plat_psci_ops.system_reset()
+............................
+
+This function is called by PSCI implementation in response to a ``SYSTEM_RESET``
+call. It performs the platform-specific system reset sequence after
+notifying the Secure Payload Dispatcher.
+
+plat_psci_ops.validate_power_state()
+....................................
+
+This function is called by the PSCI implementation during the ``CPU_SUSPEND``
+call to validate the ``power_state`` parameter of the PSCI API and if valid,
+populate it in ``req_state`` (second argument) array as power domain level
+specific local states. If the ``power_state`` is invalid, the platform must
+return PSCI_E_INVALID_PARAMS as error, which is propagated back to the
+normal world PSCI client.
+
+plat_psci_ops.validate_ns_entrypoint()
+......................................
+
+This function is called by the PSCI implementation during the ``CPU_SUSPEND``,
+``SYSTEM_SUSPEND`` and ``CPU_ON`` calls to validate the non-secure ``entry_point``
+parameter passed by the normal world. If the ``entry_point`` is invalid,
+the platform must return PSCI_E_INVALID_ADDRESS as error, which is
+propagated back to the normal world PSCI client.
+
+plat_psci_ops.get_sys_suspend_power_state()
+...........................................
+
+This function is called by the PSCI implementation during the ``SYSTEM_SUSPEND``
+call to get the ``req_state`` parameter from platform which encodes the power
+domain level specific local states to suspend to system affinity level. The
+``req_state`` will be utilized to do the PSCI state coordination and
+``pwr_domain_suspend()`` will be invoked with the coordinated target state to
+enter system suspend.
+
+plat_psci_ops.get_pwr_lvl_state_idx()
+.....................................
+
+This is an optional function and, if implemented, is invoked by the PSCI
+implementation to convert the ``local_state`` (first argument) at a specified
+``pwr_lvl`` (second argument) to an index between 0 and
+``PLAT_MAX_PWR_LVL_STATES`` - 1. This function is only needed if the platform
+supports more than two local power states at each power domain level, that is
+``PLAT_MAX_PWR_LVL_STATES`` is greater than 2, and needs to account for these
+local power states.
+
+plat_psci_ops.translate_power_state_by_mpidr()
+..............................................
+
+This is an optional function and, if implemented, verifies the ``power_state``
+(second argument) parameter of the PSCI API corresponding to a target power
+domain. The target power domain is identified by using both ``MPIDR`` (first
+argument) and the power domain level encoded in ``power_state``. The power domain
+level specific local states are to be extracted from ``power_state`` and be
+populated in the ``output_state`` (third argument) array. The functionality
+is similar to the ``validate_power_state`` function described above and is
+envisaged to be used in case the validity of ``power_state`` depend on the
+targeted power domain. If the ``power_state`` is invalid for the targeted power
+domain, the platform must return PSCI_E_INVALID_PARAMS as error. If this
+function is not implemented, then the generic implementation relies on
+``validate_power_state`` function to translate the ``power_state``.
+
+This function can also be used in case the platform wants to support local
+power state encoding for ``power_state`` parameter of PSCI_STAT_COUNT/RESIDENCY
+APIs as described in Section 5.18 of `PSCI`_.
+
+plat_psci_ops.get_node_hw_state()
+.................................
+
+This is an optional function. If implemented this function is intended to return
+the power state of a node (identified by the first parameter, the ``MPIDR``) in
+the power domain topology (identified by the second parameter, ``power_level``),
+as retrieved from a power controller or equivalent component on the platform.
+Upon successful completion, the implementation must map and return the final
+status among ``HW_ON``, ``HW_OFF`` or ``HW_STANDBY``. Upon encountering failures, it
+must return either ``PSCI_E_INVALID_PARAMS`` or ``PSCI_E_NOT_SUPPORTED`` as
+appropriate.
+
+Implementations are not expected to handle ``power_levels`` greater than
+``PLAT_MAX_PWR_LVL``.
+
+plat_psci_ops.system_reset2()
+.............................
+
+This is an optional function. If implemented this function is
+called during the ``SYSTEM_RESET2`` call to perform a reset
+based on the first parameter ``reset_type`` as specified in
+`PSCI`_. The parameter ``cookie`` can be used to pass additional
+reset information. If the ``reset_type`` is not supported, the
+function must return ``PSCI_E_NOT_SUPPORTED``. For architectural
+resets, all failures must return ``PSCI_E_INVALID_PARAMETERS``
+and vendor reset can return other PSCI error codes as defined
+in `PSCI`_. On success this function will not return.
+
+plat_psci_ops.write_mem_protect()
+.................................
+
+This is an optional function. If implemented it enables or disables the
+``MEM_PROTECT`` functionality based on the value of ``val``.
+A non-zero value enables ``MEM_PROTECT`` and a value of zero
+disables it. Upon encountering failures it must return a negative value
+and on success it must return 0.
+
+plat_psci_ops.read_mem_protect()
+................................
+
+This is an optional function. If implemented it returns the current
+state of ``MEM_PROTECT`` via the ``val`` parameter.  Upon encountering
+failures it must return a negative value and on success it must
+return 0.
+
+plat_psci_ops.mem_protect_chk()
+...............................
+
+This is an optional function. If implemented it checks if a memory
+region defined by a base address ``base`` and with a size of ``length``
+bytes is protected by ``MEM_PROTECT``.  If the region is protected
+then it must return 0, otherwise it must return a negative number.

+
+Interrupt Management framework (in BL31)
+----------------------------------------
+
+BL31 implements an Interrupt Management Framework (IMF) to manage interrupts
+generated in either security state and targeted to EL1 or EL2 in the non-secure
+state or EL3/S-EL1 in the secure state. The design of this framework is
+described in the :ref:`Interrupt Management Framework`
+
+A platform should export the following APIs to support the IMF. The following
+text briefly describes each API and its implementation in Arm standard
+platforms. The API implementation depends upon the type of interrupt controller
+present in the platform. Arm standard platform layer supports both
+`Arm Generic Interrupt Controller version 2.0 (GICv2)`_
+and `3.0 (GICv3)`_. Juno builds the Arm platform layer to use GICv2 and the
+FVP can be configured to use either GICv2 or GICv3 depending on the build flag
+``FVP_USE_GIC_DRIVER`` (See :ref:`build_options_arm_fvp_platform` for more
+details).
+
+See also: :ref:`Interrupt Controller Abstraction APIs<Platform Interrupt Controller API>`.
+
+Function : plat_interrupt_type_to_line() [mandatory]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : uint32_t, uint32_t
+    Return   : uint32_t
+
+The Arm processor signals an interrupt exception either through the IRQ or FIQ
+interrupt line. The specific line that is signaled depends on how the interrupt
+controller (IC) reports different interrupt types from an execution context in
+either security state. The IMF uses this API to determine which interrupt line
+the platform IC uses to signal each type of interrupt supported by the framework
+from a given security state. This API must be invoked at EL3.
+
+The first parameter will be one of the ``INTR_TYPE_*`` values (see
+:ref:`Interrupt Management Framework`) indicating the target type of the
+interrupt, the second parameter is the security state of the originating
+execution context. The return result is the bit position in the ``SCR_EL3``
+register of the respective interrupt trap: IRQ=1, FIQ=2.
+
+In the case of Arm standard platforms using GICv2, S-EL1 interrupts are
+configured as FIQs and Non-secure interrupts as IRQs from either security
+state.
+
+In the case of Arm standard platforms using GICv3, the interrupt line to be
+configured depends on the security state of the execution context when the
+interrupt is signalled and are as follows:
+
+-  The S-EL1 interrupts are signaled as IRQ in S-EL0/1 context and as FIQ in
+   NS-EL0/1/2 context.
+-  The Non secure interrupts are signaled as FIQ in S-EL0/1 context and as IRQ
+   in the NS-EL0/1/2 context.
+-  The EL3 interrupts are signaled as FIQ in both S-EL0/1 and NS-EL0/1/2
+   context.
+
+Function : plat_ic_get_pending_interrupt_type() [mandatory]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void
+    Return   : uint32_t
+
+This API returns the type of the highest priority pending interrupt at the
+platform IC. The IMF uses the interrupt type to retrieve the corresponding
+handler function. ``INTR_TYPE_INVAL`` is returned when there is no interrupt
+pending. The valid interrupt types that can be returned are ``INTR_TYPE_EL3``,
+``INTR_TYPE_S_EL1`` and ``INTR_TYPE_NS``. This API must be invoked at EL3.
+
+In the case of Arm standard platforms using GICv2, the *Highest Priority
+Pending Interrupt Register* (``GICC_HPPIR``) is read to determine the id of
+the pending interrupt. The type of interrupt depends upon the id value as
+follows.
+
+#. id < 1022 is reported as a S-EL1 interrupt
+#. id = 1022 is reported as a Non-secure interrupt.
+#. id = 1023 is reported as an invalid interrupt type.
+
+In the case of Arm standard platforms using GICv3, the system register
+``ICC_HPPIR0_EL1``, *Highest Priority Pending group 0 Interrupt Register*,
+is read to determine the id of the pending interrupt. The type of interrupt
+depends upon the id value as follows.
+
+#. id = ``PENDING_G1S_INTID`` (1020) is reported as a S-EL1 interrupt
+#. id = ``PENDING_G1NS_INTID`` (1021) is reported as a Non-secure interrupt.
+#. id = ``GIC_SPURIOUS_INTERRUPT`` (1023) is reported as an invalid interrupt type.
+#. All other interrupt id's are reported as EL3 interrupt.
+
+Function : plat_ic_get_pending_interrupt_id() [mandatory]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void
+    Return   : uint32_t
+
+This API returns the id of the highest priority pending interrupt at the
+platform IC. ``INTR_ID_UNAVAILABLE`` is returned when there is no interrupt
+pending.
+
+In the case of Arm standard platforms using GICv2, the *Highest Priority
+Pending Interrupt Register* (``GICC_HPPIR``) is read to determine the id of the
+pending interrupt. The id that is returned by API depends upon the value of
+the id read from the interrupt controller as follows.
+
+#. id < 1022. id is returned as is.
+#. id = 1022. The *Aliased Highest Priority Pending Interrupt Register*
+   (``GICC_AHPPIR``) is read to determine the id of the non-secure interrupt.
+   This id is returned by the API.
+#. id = 1023. ``INTR_ID_UNAVAILABLE`` is returned.
+
+In the case of Arm standard platforms using GICv3, if the API is invoked from
+EL3, the system register ``ICC_HPPIR0_EL1``, *Highest Priority Pending Interrupt
+group 0 Register*, is read to determine the id of the pending interrupt. The id
+that is returned by API depends upon the value of the id read from the
+interrupt controller as follows.
+
+#. id < ``PENDING_G1S_INTID`` (1020). id is returned as is.
+#. id = ``PENDING_G1S_INTID`` (1020) or ``PENDING_G1NS_INTID`` (1021). The system
+   register ``ICC_HPPIR1_EL1``, *Highest Priority Pending Interrupt group 1
+   Register* is read to determine the id of the group 1 interrupt. This id
+   is returned by the API as long as it is a valid interrupt id
+#. If the id is any of the special interrupt identifiers,
+   ``INTR_ID_UNAVAILABLE`` is returned.
+
+When the API invoked from S-EL1 for GICv3 systems, the id read from system
+register ``ICC_HPPIR1_EL1``, *Highest Priority Pending group 1 Interrupt
+Register*, is returned if is not equal to GIC_SPURIOUS_INTERRUPT (1023) else
+``INTR_ID_UNAVAILABLE`` is returned.
+
+Function : plat_ic_acknowledge_interrupt() [mandatory]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void
+    Return   : uint32_t
+
+This API is used by the CPU to indicate to the platform IC that processing of
+the highest pending interrupt has begun. It should return the raw, unmodified
+value obtained from the interrupt controller when acknowledging an interrupt.
+The actual interrupt number shall be extracted from this raw value using the API
+`plat_ic_get_interrupt_id()<plat_ic_get_interrupt_id>`.
+
+This function in Arm standard platforms using GICv2, reads the *Interrupt
+Acknowledge Register* (``GICC_IAR``). This changes the state of the highest
+priority pending interrupt from pending to active in the interrupt controller.
+It returns the value read from the ``GICC_IAR``, unmodified.
+
+In the case of Arm standard platforms using GICv3, if the API is invoked
+from EL3, the function reads the system register ``ICC_IAR0_EL1``, *Interrupt
+Acknowledge Register group 0*. If the API is invoked from S-EL1, the function
+reads the system register ``ICC_IAR1_EL1``, *Interrupt Acknowledge Register
+group 1*. The read changes the state of the highest pending interrupt from
+pending to active in the interrupt controller. The value read is returned
+unmodified.
+
+The TSP uses this API to start processing of the secure physical timer
+interrupt.
+
+Function : plat_ic_end_of_interrupt() [mandatory]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : uint32_t
+    Return   : void
+
+This API is used by the CPU to indicate to the platform IC that processing of
+the interrupt corresponding to the id (passed as the parameter) has
+finished. The id should be the same as the id returned by the
+``plat_ic_acknowledge_interrupt()`` API.
+
+Arm standard platforms write the id to the *End of Interrupt Register*
+(``GICC_EOIR``) in case of GICv2, and to ``ICC_EOIR0_EL1`` or ``ICC_EOIR1_EL1``
+system register in case of GICv3 depending on where the API is invoked from,
+EL3 or S-EL1. This deactivates the corresponding interrupt in the interrupt
+controller.
+
+The TSP uses this API to finish processing of the secure physical timer
+interrupt.
+
+Function : plat_ic_get_interrupt_type() [mandatory]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : uint32_t
+    Return   : uint32_t
+
+This API returns the type of the interrupt id passed as the parameter.
+``INTR_TYPE_INVAL`` is returned if the id is invalid. If the id is valid, a valid
+interrupt type (one of ``INTR_TYPE_EL3``, ``INTR_TYPE_S_EL1`` and ``INTR_TYPE_NS``) is
+returned depending upon how the interrupt has been configured by the platform
+IC. This API must be invoked at EL3.
+
+Arm standard platforms using GICv2 configures S-EL1 interrupts as Group0 interrupts
+and Non-secure interrupts as Group1 interrupts. It reads the group value
+corresponding to the interrupt id from the relevant *Interrupt Group Register*
+(``GICD_IGROUPRn``). It uses the group value to determine the type of interrupt.
+
+In the case of Arm standard platforms using GICv3, both the *Interrupt Group
+Register* (``GICD_IGROUPRn``) and *Interrupt Group Modifier Register*
+(``GICD_IGRPMODRn``) is read to figure out whether the interrupt is configured
+as Group 0 secure interrupt, Group 1 secure interrupt or Group 1 NS interrupt.
+
+Common helper functions
+-----------------------
+
+Function : do_panic()
+~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void
+    Return   : void
+
+This API is called from assembly files when encountering a critical failure that
+cannot be recovered from. It also invokes elx_panic() which allows to report a
+crash from lower exception level. This function assumes that it is invoked from
+a C runtime environment i.e. valid stack exists. This call **must not** return.
+
+Function : panic()
+~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void
+    Return   : void
+
+This API called from C files when encountering a critical failure that cannot
+be recovered from. This function in turn prints backtrace (if enabled) and calls
+do_panic(). This call **must not** return.
+
+Crash Reporting mechanism (in BL31)
+-----------------------------------
+
+BL31 implements a crash reporting mechanism which prints the various registers
+of the CPU to enable quick crash analysis and debugging. This mechanism relies
+on the platform implementing ``plat_crash_console_init``,
+``plat_crash_console_putc`` and ``plat_crash_console_flush``.
+
+The file ``plat/common/aarch64/crash_console_helpers.S`` contains sample
+implementation of all of them. Platforms may include this file to their
+makefiles in order to benefit from them. By default, they will cause the crash
+output to be routed over the normal console infrastructure and get printed on
+consoles configured to output in crash state. ``console_set_scope()`` can be
+used to control whether a console is used for crash output.
+
+.. note::
+   Platforms are responsible for making sure that they only mark consoles for
+   use in the crash scope that are able to support this, i.e. that are written
+   in assembly and conform with the register clobber rules for putc()
+   (x0-x2, x16-x17) and flush() (x0-x3, x16-x17) crash callbacks.
+
+In some cases (such as debugging very early crashes that happen before the
+normal boot console can be set up), platforms may want to control crash output
+more explicitly. These platforms may instead provide custom implementations for
+these. They are executed outside of a C environment and without a stack. Many
+console drivers provide functions named ``console_xxx_core_init/putc/flush``
+that are designed to be used by these functions. See Arm platforms (like juno)
+for an example of this.
+
+Function : plat_crash_console_init [mandatory]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void
+    Return   : int
+
+This API is used by the crash reporting mechanism to initialize the crash
+console. It must only use the general purpose registers x0 through x7 to do the
+initialization and returns 1 on success.
+
+Function : plat_crash_console_putc [mandatory]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : int
+    Return   : int
+
+This API is used by the crash reporting mechanism to print a character on the
+designated crash console. It must only use general purpose registers x1 and
+x2 to do its work. The parameter and the return value are in general purpose
+register x0.
+
+Function : plat_crash_console_flush [mandatory]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void
+    Return   : void
+
+This API is used by the crash reporting mechanism to force write of all buffered
+data on the designated crash console. It should only use general purpose
+registers x0 through x5 to do its work.
+
+.. _External Abort handling and RAS Support:
+
+External Abort handling and RAS Support
+---------------------------------------
+
+Function : plat_ea_handler
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : int
+    Argument : uint64_t
+    Argument : void *
+    Argument : void *
+    Argument : uint64_t
+    Return   : void
+
+This function is invoked by the RAS framework for the platform to handle an
+External Abort received at EL3. The intention of the function is to attempt to
+resolve the cause of External Abort and return; if that's not possible, to
+initiate orderly shutdown of the system.
+
+The first parameter (``int ea_reason``) indicates the reason for External Abort.
+Its value is one of ``ERROR_EA_*`` constants defined in ``ea_handle.h``.
+
+The second parameter (``uint64_t syndrome``) is the respective syndrome
+presented to EL3 after having received the External Abort. Depending on the
+nature of the abort (as can be inferred from the ``ea_reason`` parameter), this
+can be the content of either ``ESR_EL3`` or ``DISR_EL1``.
+
+The third parameter (``void *cookie``) is unused for now. The fourth parameter
+(``void *handle``) is a pointer to the preempted context. The fifth parameter
+(``uint64_t flags``) indicates the preempted security state. These parameters
+are received from the top-level exception handler.
+
+If ``RAS_EXTENSION`` is set to ``1``, the default implementation of this
+function iterates through RAS handlers registered by the platform. If any of the
+RAS handlers resolve the External Abort, no further action is taken.
+
+If ``RAS_EXTENSION`` is set to ``0``, or if none of the platform RAS handlers
+could resolve the External Abort, the default implementation prints an error
+message, and panics.
+
+Function : plat_handle_uncontainable_ea
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : int
+    Argument : uint64_t
+    Return   : void
+
+This function is invoked by the RAS framework when an External Abort of
+Uncontainable type is received at EL3. Due to the critical nature of
+Uncontainable errors, the intention of this function is to initiate orderly
+shutdown of the system, and is not expected to return.
+
+This function must be implemented in assembly.
+
+The first and second parameters are the same as that of ``plat_ea_handler``.
+
+The default implementation of this function calls
+``report_unhandled_exception``.
+
+Function : plat_handle_double_fault
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : int
+    Argument : uint64_t
+    Return   : void
+
+This function is invoked by the RAS framework when another External Abort is
+received at EL3 while one is already being handled. I.e., a call to
+``plat_ea_handler`` is outstanding. Due to its critical nature, the intention of
+this function is to initiate orderly shutdown of the system, and is not expected
+recover or return.
+
+This function must be implemented in assembly.
+
+The first and second parameters are the same as that of ``plat_ea_handler``.
+
+The default implementation of this function calls
+``report_unhandled_exception``.
+
+Function : plat_handle_el3_ea
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Return   : void
+
+This function is invoked when an External Abort is received while executing in
+EL3. Due to its critical nature, the intention of this function is to initiate
+orderly shutdown of the system, and is not expected recover or return.
+
+This function must be implemented in assembly.
+
+The default implementation of this function calls
+``report_unhandled_exception``.
+
+Build flags
+-----------
+
+There are some build flags which can be defined by the platform to control
+inclusion or exclusion of certain BL stages from the FIP image. These flags
+need to be defined in the platform makefile which will get included by the
+build system.
+
+-  **NEED_BL33**
+   By default, this flag is defined ``yes`` by the build system and ``BL33``
+   build option should be supplied as a build option. The platform has the
+   option of excluding the BL33 image in the ``fip`` image by defining this flag
+   to ``no``. If any of the options ``EL3_PAYLOAD_BASE`` or ``PRELOADED_BL33_BASE``
+   are used, this flag will be set to ``no`` automatically.
+
+Platform include paths
+----------------------
+
+Platforms are allowed to add more include paths to be passed to the compiler.
+The ``PLAT_INCLUDES`` variable is used for this purpose. This is needed in
+particular for the file ``platform_def.h``.
+
+Example:
+
+.. code:: c
+
+  PLAT_INCLUDES  += -Iinclude/plat/myplat/include
+
+C Library
+---------
+
+To avoid subtle toolchain behavioral dependencies, the header files provided
+by the compiler are not used. The software is built with the ``-nostdinc`` flag
+to ensure no headers are included from the toolchain inadvertently. Instead the
+required headers are included in the TF-A source tree. The library only
+contains those C library definitions required by the local implementation. If
+more functionality is required, the needed library functions will need to be
+added to the local implementation.
+
+Some C headers have been obtained from `FreeBSD`_ and `SCC`_, while others have
+been written specifically for TF-A. Some implementation files have been obtained
+from `FreeBSD`_, others have been written specifically for TF-A as well. The
+files can be found in ``include/lib/libc`` and ``lib/libc``.
+
+SCC can be found in http://www.simple-cc.org/. A copy of the `FreeBSD`_ sources
+can be obtained from http://github.com/freebsd/freebsd.
+
+Storage abstraction layer
+-------------------------
+
+In order to improve platform independence and portability a storage abstraction
+layer is used to load data from non-volatile platform storage. Currently
+storage access is only required by BL1 and BL2 phases and performed inside the
+``load_image()`` function in ``bl_common.c``.
+
+.. uml:: ../resources/diagrams/plantuml/io_framework_usage_overview.puml
+
+It is mandatory to implement at least one storage driver. For the Arm
+development platforms the Firmware Image Package (FIP) driver is provided as
+the default means to load data from storage (see :ref:`firmware_design_fip`).
+The storage layer is described in the header file
+``include/drivers/io/io_storage.h``. The implementation of the common library is
+in ``drivers/io/io_storage.c`` and the driver files are located in
+``drivers/io/``.
+
+.. uml:: ../resources/diagrams/plantuml/io_arm_class_diagram.puml
+
+Each IO driver must provide ``io_dev_*`` structures, as described in
+``drivers/io/io_driver.h``. These are returned via a mandatory registration
+function that is called on platform initialization. The semi-hosting driver
+implementation in ``io_semihosting.c`` can be used as an example.
+
+Each platform should register devices and their drivers via the storage
+abstraction layer. These drivers then need to be initialized by bootloader
+phases as required in their respective ``blx_platform_setup()`` functions.
+
+.. uml:: ../resources/diagrams/plantuml/io_dev_registration.puml
+
+The storage abstraction layer provides mechanisms (``io_dev_init()``) to
+initialize storage devices before IO operations are called.
+
+.. uml:: ../resources/diagrams/plantuml/io_dev_init_and_check.puml
+
+The basic operations supported by the layer
+include ``open()``, ``close()``, ``read()``, ``write()``, ``size()`` and ``seek()``.
+Drivers do not have to implement all operations, but each platform must
+provide at least one driver for a device capable of supporting generic
+operations such as loading a bootloader image.
+
+The current implementation only allows for known images to be loaded by the
+firmware. These images are specified by using their identifiers, as defined in
+``include/plat/common/common_def.h`` (or a separate header file included from
+there). The platform layer (``plat_get_image_source()``) then returns a reference
+to a device and a driver-specific ``spec`` which will be understood by the driver
+to allow access to the image data.
+
+The layer is designed in such a way that is it possible to chain drivers with
+other drivers. For example, file-system drivers may be implemented on top of
+physical block devices, both represented by IO devices with corresponding
+drivers. In such a case, the file-system "binding" with the block device may
+be deferred until the file-system device is initialised.
+
+The abstraction currently depends on structures being statically allocated
+by the drivers and callers, as the system does not yet provide a means of
+dynamically allocating memory. This may also have the affect of limiting the
+amount of open resources per driver.

+Prerequisites
+=============
+
+This document describes the software requirements for building |TF-A| for
+AArch32 and AArch64 target platforms.
+
+It may possible to build |TF-A| with combinations of software packages that are
+different from those listed below, however only the software described in this
+document can be officially supported.
+
+Build Host
+----------
+
+|TF-A| can be built using either a Linux or a Windows machine as the build host.
+
+A relatively recent Linux distribution is recommended for building |TF-A|. We
+have performed tests using Ubuntu 20.04 LTS (64-bit) but other distributions
+should also work fine as a base, provided that the necessary tools and libraries
+can be installed.
+
+.. _prerequisites_toolchain:
+
+Toolchain
+---------
+
+|TF-A| can be built with any of the following *cross-compiler* toolchains that
+target the Armv7-A or Armv8-A architectures:
+
+- GCC >= 11.3.Rel1 (from the `Arm Developer website`_)
+
+   You will need the targets ``arm-none-eabi`` and ``aarch64-none-elf`` for
+   AArch32 and AArch64 builds respectively.
+
+- Clang >= 14.0.0
+- Arm Compiler >= 6.18
+
+In addition, a native compiler is required to build the supporting tools.
+
+.. note::
+   The software has also been built on Windows 7 Enterprise SP1, using CMD.EXE,
+   Cygwin, and Msys (MinGW) shells, using version 5.3.1 of the GNU toolchain.
+
+.. note::
+   For instructions on how to select the cross compiler refer to
+   :ref:`Performing an Initial Build`.
+
+.. _prerequisites_software_and_libraries:
+
+Software and Libraries
+----------------------
+
+The following tools are required to obtain and build |TF-A|:
+
+- An appropriate toolchain (see :ref:`prerequisites_toolchain`)
+- GNU Make
+- Git
+
+The following libraries must be available to build one or more components or
+supporting tools:
+
+- OpenSSL >= 1.1.1 (v3.0.0 to v3.0.6 highly discouraged due to security issues)
+
+   Required to build the cert_create, encrypt_fw, and fiptool tools.
+
+   .. note::
+
+    If using OpenSSL 3, older Linux versions may require it to be built from
+    source code, as it may not be available in the default package repositories.
+    Please refer to the OpenSSL project documentation for more information.
+
+The following libraries are required for Trusted Board Boot and Measured Boot
+support:
+
+- mbed TLS == 2.28.1 (tag: ``mbedtls-2.28.1``)
+
+These tools are optional:
+
+- Device Tree Compiler (DTC) >= 1.4.6
+
+   Needed if you want to rebuild the provided Flattened Device Tree (FDT)
+   source files (``.dts`` files). DTC is available for Linux through the package
+   repositories of most distributions.
+
+- Arm `Development Studio (Arm-DS)`_
+
+   The standard software package used for debugging software on Arm development
+   platforms and |FVP| models.
+
+- Node.js >= 16
+
+   Highly recommended, and necessary in order to install and use the packaged
+   Git hooks and helper tools. Without these tools you will need to rely on the
+   CI for feedback on commit message conformance.
+
+Package Installation (Linux)
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+If you are using the recommended Ubuntu distribution then you can install the
+required packages with the following command:
+
+.. code:: shell
+
+    sudo apt install build-essential git
+
+The optional packages can be installed using:
+
+.. code:: shell
+
+    sudo apt install device-tree-compiler
+
+Additionally, to install a version of Node.js compatible with TF-A's repository
+scripts, you can use the `Node Version Manager`_. To install both NVM and an
+appropriate version of Node.js, run the following **from the root directory of
+the repository**:
+
+.. code:: shell
+
+    curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash
+    exec "$SHELL" -ic "nvm install; exec $SHELL"
+
+.. _Node Version Manager: https://github.com/nvm-sh/nvm#install--update-script
+
+Supporting Files
+----------------
+
+TF-A has been tested with pre-built binaries and file systems from `Linaro
+Release 20.01`_. Alternatively, you can build the binaries from source using
+instructions in :ref:`Performing an Initial Build`.
+
+.. _prerequisites_get_source:
+
+Getting the TF-A Source
+-----------------------
+
+Source code for |TF-A| is maintained in a Git repository hosted on
+TrustedFirmware.org. To clone this repository from the server, run the following
+in your shell:
+
+.. code:: shell
+
+    git clone "https://review.trustedfirmware.org/TF-A/trusted-firmware-a"
+
+Additional Steps for Contributors
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+If you are planning on contributing back to TF-A, there are some things you'll
+want to know.
+
+TF-A is hosted by a `Gerrit Code Review`_ server. Gerrit requires that all
+commits include a ``Change-Id`` footer, and this footer is typically
+automatically generated by a Git hook installed by you, the developer.
+
+If you have Node.js installed already, you can automatically install this hook,
+along with any additional hooks and Javascript-based tooling that we use, by
+running from within your newly-cloned repository:
+
+.. code:: shell
+
+    npm install --no-save
+
+If you have opted **not** to install Node.js, you can install the Gerrit hook
+manually by running:
+
+.. code:: shell
+
+    curl -Lo $(git rev-parse --git-dir)/hooks/commit-msg https://review.trustedfirmware.org/tools/hooks/commit-msg
+    chmod +x $(git rev-parse --git-dir)/hooks/commit-msg
+
+You can read more about Git hooks in the *githooks* page of the Git
+documentation, available `here <https://git-scm.com/docs/githooks>`_.

+PSCI Library Integration guide for Armv8-A AArch32 systems
+==========================================================
+
+This document describes the PSCI library interface with a focus on how to
+integrate with a suitable Trusted OS for an Armv8-A AArch32 system. The PSCI
+Library implements the PSCI Standard as described in `PSCI spec`_ and is meant
+to be integrated with EL3 Runtime Software which invokes the PSCI Library
+interface appropriately. **EL3 Runtime Software** refers to software executing
+at the highest secure privileged mode, which is EL3 in AArch64 or Secure SVC/
+Monitor mode in AArch32, and provides runtime services to the non-secure world.
+The runtime service request is made via SMC (Secure Monitor Call) and the call
+must adhere to `SMCCC`_. In AArch32, EL3 Runtime Software may additionally
+include Trusted OS functionality. A minimal AArch32 Secure Payload, SP-MIN, is
+provided in Trusted Firmware-A (TF-A) to illustrate the usage and integration
+of the PSCI library. The description of PSCI library interface and its
+integration with EL3 Runtime Software in this document is targeted towards
+AArch32 systems.
+
+Generic call sequence for PSCI Library interface (AArch32)
+----------------------------------------------------------
+
+The generic call sequence of PSCI Library interfaces (see
+`PSCI Library Interface`_) during cold boot in AArch32
+system is described below:
+
+#. After cold reset, the EL3 Runtime Software performs its cold boot
+   initialization including the PSCI library pre-requisites mentioned in
+   `PSCI Library Interface`_, and also the necessary platform
+   setup.
+
+#. Call ``psci_setup()`` in Monitor mode.
+
+#. Optionally call ``psci_register_spd_pm_hook()`` to register callbacks to
+   do bookkeeping for the EL3 Runtime Software during power management.
+
+#. Call ``psci_prepare_next_non_secure_ctx()`` to initialize the non-secure CPU
+   context.
+
+#. Get the non-secure ``cpu_context_t`` for the current CPU by calling
+   ``cm_get_context()`` , then programming the registers in the non-secure
+   context and exiting to non-secure world. If the EL3 Runtime Software needs
+   additional configuration to be set for non-secure context, like routing
+   FIQs to the secure world, the values of the registers can be modified prior
+   to programming. See `PSCI CPU context management`_ for more
+   details on CPU context management.
+
+The generic call sequence of PSCI library interfaces during warm boot in
+AArch32 systems is described below:
+
+#. After warm reset, the EL3 Runtime Software performs the necessary warm
+   boot initialization including the PSCI library pre-requisites mentioned in
+   `PSCI Library Interface`_ (Note that the Data cache
+   **must not** be enabled).
+
+#. Call ``psci_warmboot_entrypoint()`` in Monitor mode. This interface
+   initializes/restores the non-secure CPU context as well.
+
+#. Do step 5 of the cold boot call sequence described above.
+
+The generic call sequence of PSCI library interfaces on receipt of a PSCI SMC
+on an AArch32 system is described below:
+
+#. On receipt of an SMC, save the register context as per `SMCCC`_.
+
+#. If the SMC function identifier corresponds to a SMC32 PSCI API, construct
+   the appropriate arguments and call the ``psci_smc_handler()`` interface.
+   The invocation may or may not return back to the caller depending on
+   whether the PSCI API resulted in power down of the CPU.
+
+#. If ``psci_smc_handler()`` returns, populate the return value in R0 (AArch32)/
+   X0 (AArch64) and restore other registers as per `SMCCC`_.
+
+PSCI CPU context management
+---------------------------
+
+PSCI library is in charge of initializing/restoring the non-secure CPU system
+registers according to `PSCI specification`_ during cold/warm boot.
+This is referred to as ``PSCI CPU Context Management``. Registers that need to
+be preserved across CPU power down/power up cycles are maintained in
+``cpu_context_t`` data structure. The initialization of other non-secure CPU
+system registers which do not require coordination with the EL3 Runtime
+Software is done directly by the PSCI library (see ``cm_prepare_el3_exit()``).
+
+The EL3 Runtime Software is responsible for managing register context
+during switch between Normal and Secure worlds. The register context to be
+saved and restored depends on the mechanism used to trigger the world switch.
+For example, if the world switch was triggered by an SMC call, then the
+registers need to be saved and restored according to `SMCCC`_. In AArch64,
+due to the tight integration with BL31, both BL31 and PSCI library
+use the same ``cpu_context_t`` data structure for PSCI CPU context management
+and register context management during world switch. This cannot be assumed
+for AArch32 EL3 Runtime Software since most AArch32 Trusted OSes already implement
+a mechanism for register context management during world switch. Hence, when
+the PSCI library is integrated with a AArch32 EL3 Runtime Software, the
+``cpu_context_t`` is stripped down for just PSCI CPU context management.
+
+During cold/warm boot, after invoking appropriate PSCI library interfaces, it
+is expected that the EL3 Runtime Software will query the ``cpu_context_t`` and
+write appropriate values to the corresponding system registers. This mechanism
+resolves 2 additional problems for AArch32 EL3 Runtime Software:
+
+#. Values for certain system registers like SCR and SCTLR cannot be
+   unilaterally determined by PSCI library and need inputs from the EL3
+   Runtime Software. Using ``cpu_context_t`` as an intermediary data store
+   allows EL3 Runtime Software to modify the register values appropriately
+   before programming them.
+
+#. The PSCI library provides appropriate LR and SPSR values (entrypoint
+   information) for exit into non-secure world. Using ``cpu_context_t`` as an
+   intermediary data store allows the EL3 Runtime Software to store these
+   values safely until it is ready for exit to non-secure world.
+
+Currently the ``cpu_context_t`` data structure for AArch32 stores the following
+registers: R0 - R3, LR (R14), SCR, SPSR, SCTLR.
+
+The EL3 Runtime Software must implement accessors to get/set pointers
+to CPU context ``cpu_context_t`` data and these are described in
+`CPU Context management API`_.
+
+PSCI Library Interface
+----------------------
+
+The PSCI library implements the `PSCI Specification`_. The interfaces
+to this library are declared in ``psci_lib.h`` and are as listed below:
+
+.. code:: c
+
+        u_register_t psci_smc_handler(uint32_t smc_fid, u_register_t x1,
+                                      u_register_t x2, u_register_t x3,
+                                      u_register_t x4, void *cookie,
+                                      void *handle, u_register_t flags);
+        int psci_setup(const psci_lib_args_t *lib_args);
+        void psci_warmboot_entrypoint(void);
+        void psci_register_spd_pm_hook(const spd_pm_ops_t *pm);
+        void psci_prepare_next_non_secure_ctx(entry_point_info_t *next_image_info);
+
+The CPU context data 'cpu_context_t' is programmed to the registers differently
+when PSCI is integrated with an AArch32 EL3 Runtime Software compared to
+when the PSCI is integrated with an AArch64 EL3 Runtime Software (BL31). For
+example, in the case of AArch64, there is no need to retrieve ``cpu_context_t``
+data and program the registers as it will done implicitly as part of
+``el3_exit``. The description below of the PSCI interfaces is targeted at
+integration with an AArch32 EL3 Runtime Software.
+
+The PSCI library is responsible for initializing/restoring the non-secure world
+to an appropriate state after boot and may choose to directly program the
+non-secure system registers. The PSCI generic code takes care not to directly
+modify any of the system registers affecting the secure world and instead
+returns the values to be programmed to these registers via ``cpu_context_t``.
+The EL3 Runtime Software is responsible for programming those registers and
+can use the proposed values provided in the ``cpu_context_t``, modifying the
+values if required.
+
+PSCI library needs the flexibility to access both secure and non-secure
+copies of banked registers. Hence it needs to be invoked in Monitor mode
+for AArch32 and in EL3 for AArch64. The NS bit in SCR (in AArch32) or SCR_EL3
+(in AArch64) must be set to 0. Additional requirements for the PSCI library
+interfaces are:
+
+-  Instruction cache must be enabled
+-  Both IRQ and FIQ must be masked for the current CPU
+-  The page tables must be setup and the MMU enabled
+-  The C runtime environment must be setup and stack initialized
+-  The Data cache must be enabled prior to invoking any of the PSCI library
+   interfaces except for ``psci_warmboot_entrypoint()``. For
+   ``psci_warmboot_entrypoint()``, if the build option ``HW_ASSISTED_COHERENCY``
+   is enabled however, data caches are expected to be enabled.
+
+Further requirements for each interface can be found in the interface
+description.
+
+Interface : psci_setup()
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : const psci_lib_args_t *lib_args
+    Return   : void
+
+This function is to be called by the primary CPU during cold boot before
+any other interface to the PSCI library. It takes ``lib_args``, a const pointer
+to ``psci_lib_args_t``, as the argument. The ``psci_lib_args_t`` is a versioned
+structure and is declared in ``psci_lib.h`` header as follows:
+
+.. code:: c
+
+        typedef struct psci_lib_args {
+            /* The version information of PSCI Library Interface */
+            param_header_t        h;
+            /* The warm boot entrypoint function */
+            mailbox_entrypoint_t  mailbox_ep;
+        } psci_lib_args_t;
+
+The first field ``h``, of ``param_header_t`` type, provides the version
+information. The second field ``mailbox_ep`` is the warm boot entrypoint address
+and is used to configure the platform mailbox. Helper macros are provided in
+``psci_lib.h`` to construct the ``lib_args`` argument statically or during
+runtime. Prior to calling the ``psci_setup()`` interface, the platform setup for
+cold boot must have completed. Major actions performed by this interface are:
+
+-  Initializes architecture.
+-  Initializes PSCI power domain and state coordination data structures.
+-  Calls ``plat_setup_psci_ops()`` with warm boot entrypoint ``mailbox_ep`` as
+   argument.
+-  Calls ``cm_set_context_by_index()`` (see
+   `CPU Context management API`_) for all the CPUs in the
+   platform
+
+Interface : psci_prepare_next_non_secure_ctx()
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : entry_point_info_t *next_image_info
+    Return   : void
+
+After ``psci_setup()`` and prior to exit to the non-secure world, this function
+must be called by the EL3 Runtime Software to initialize the non-secure world
+context. The non-secure world entrypoint information ``next_image_info`` (first
+argument) will be used to determine the non-secure context. After this function
+returns, the EL3 Runtime Software must retrieve the ``cpu_context_t`` (using
+cm_get_context()) for the current CPU and program the registers prior to exit
+to the non-secure world.
+
+Interface : psci_register_spd_pm_hook()
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : const spd_pm_ops_t *
+    Return   : void
+
+As explained in `Secure payload power management callback`_,
+the EL3 Runtime Software may want to perform some bookkeeping during power
+management operations. This function is used to register the ``spd_pm_ops_t``
+(first argument) callbacks with the PSCI library which will be called
+appropriately during power management. Calling this function is optional and
+need to be called by the primary CPU during the cold boot sequence after
+``psci_setup()`` has completed.
+
+Interface : psci_smc_handler()
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : uint32_t smc_fid, u_register_t x1,
+               u_register_t x2, u_register_t x3,
+               u_register_t x4, void *cookie,
+               void *handle, u_register_t flags
+    Return   : u_register_t
+
+This function is the top level handler for SMCs which fall within the
+PSCI service range specified in `SMCCC`_. The function ID ``smc_fid`` (first
+argument) determines the PSCI API to be called. The ``x1`` to ``x4`` (2nd to 5th
+arguments), are the values of the registers r1 - r4 (in AArch32) or x1 - x4
+(in AArch64) when the SMC is received. These are the arguments to PSCI API as
+described in `PSCI spec`_. The 'flags' (8th argument) is a bit field parameter
+and is detailed in 'smccc.h' header. It includes whether the call is from the
+secure or non-secure world. The ``cookie`` (6th argument) and the ``handle``
+(7th argument) are not used and are reserved for future use.
+
+The return value from this interface is the return value from the underlying
+PSCI API corresponding to ``smc_fid``. This function may not return back to the
+caller if PSCI API causes power down of the CPU. In this case, when the CPU
+wakes up, it will start execution from the warm reset address.
+
+Interface : psci_warmboot_entrypoint()
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+    Argument : void
+    Return   : void
+
+This function performs the warm boot initialization/restoration as mandated by
+`PSCI spec`_. For AArch32, on wakeup from power down the CPU resets to secure SVC
+mode and the EL3 Runtime Software must perform the prerequisite initializations
+mentioned at top of this section. This function must be called with Data cache
+disabled (unless build option ``HW_ASSISTED_COHERENCY`` is enabled) but with MMU
+initialized and enabled. The major actions performed by this function are:
+
+-  Invalidates the stack and enables the data cache.
+-  Initializes architecture and PSCI state coordination.
+-  Restores/Initializes the peripheral drivers to the required state via
+   appropriate ``plat_psci_ops_t`` hooks
+-  Restores the EL3 Runtime Software context via appropriate ``spd_pm_ops_t``
+   callbacks.
+-  Restores/Initializes the non-secure context and populates the
+   ``cpu_context_t`` for the current CPU.
+
+Upon the return of this function, the EL3 Runtime Software must retrieve the
+non-secure ``cpu_context_t`` using ``cm_get_context()`` and program the registers
+prior to exit to the non-secure world.
+
+EL3 Runtime Software dependencies
+---------------------------------
+
+The PSCI Library includes supporting frameworks like context management,
+cpu operations (cpu_ops) and per-cpu data framework. Other helper library
+functions like bakery locks and spin locks are also included in the library.
+The dependencies which must be fulfilled by the EL3 Runtime Software
+for integration with PSCI library are described below.
+
+General dependencies
+~~~~~~~~~~~~~~~~~~~~
+
+The PSCI library being a Multiprocessor (MP) implementation, EL3 Runtime
+Software must provide an SMC handling framework capable of MP adhering to
+`SMCCC`_ specification.
+
+The EL3 Runtime Software must also export cache maintenance primitives
+and some helper utilities for assert, print and memory operations as listed
+below. The TF-A source tree provides implementations for all
+these functions but the EL3 Runtime Software may use its own implementation.
+
+**Functions : assert(), memcpy(), memset(), printf()**
+
+These must be implemented as described in ISO C Standard.
+
+**Function : flush_dcache_range()**
+
+::
+
+    Argument : uintptr_t addr, size_t size
+    Return   : void
+
+This function cleans and invalidates (flushes) the data cache for memory
+at address ``addr`` (first argument) address and of size ``size`` (second argument).
+
+**Function : inv_dcache_range()**
+
+::
+
+    Argument : uintptr_t addr, size_t size
+    Return   : void
+
+This function invalidates (flushes) the data cache for memory at address
+``addr`` (first argument) address and of size ``size`` (second argument).
+
+CPU Context management API
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The CPU context management data memory is statically allocated by PSCI library
+in BSS section. The PSCI library requires the EL3 Runtime Software to implement
+APIs to store and retrieve pointers to this CPU context data. SP-MIN
+demonstrates how these APIs can be implemented but the EL3 Runtime Software can
+choose a more optimal implementation (like dedicating the secure TPIDRPRW
+system register (in AArch32) for storing these pointers).
+
+**Function : cm_set_context_by_index()**
+
+::
+
+    Argument : unsigned int cpu_idx, void *context, unsigned int security_state
+    Return   : void
+
+This function is called during cold boot when the ``psci_setup()`` PSCI library
+interface is called.
+
+This function must store the pointer to the CPU context data, ``context`` (2nd
+argument), for the specified ``security_state`` (3rd argument) and CPU identified
+by ``cpu_idx`` (first argument). The ``security_state`` will always be non-secure
+when called by PSCI library and this argument is retained for compatibility
+with BL31. The ``cpu_idx`` will correspond to the index returned by the
+``plat_core_pos_by_mpidr()`` for ``mpidr`` of the CPU.
+
+The actual method of storing the ``context`` pointers is implementation specific.
+For example, SP-MIN stores the pointers in the array ``sp_min_cpu_ctx_ptr``
+declared in ``sp_min_main.c``.
+
+**Function : cm_get_context()**
+
+::
+
+    Argument : uint32_t security_state
+    Return   : void *
+
+This function must return the pointer to the ``cpu_context_t`` structure for
+the specified ``security_state`` (first argument) for the current CPU. The caller
+must ensure that ``cm_set_context_by_index`` is called first and the appropriate
+context pointers are stored prior to invoking this API. The ``security_state``
+will always be non-secure when called by PSCI library and this argument
+is retained for compatibility with BL31.
+
+**Function : cm_get_context_by_index()**
+
+::
+
+    Argument : unsigned int cpu_idx, unsigned int security_state
+    Return   : void *
+
+This function must return the pointer to the ``cpu_context_t`` structure for
+the specified ``security_state`` (second argument) for the CPU identified by
+``cpu_idx`` (first argument). The caller must ensure that
+``cm_set_context_by_index`` is called first and the appropriate context
+pointers are stored prior to invoking this API. The ``security_state`` will
+always be non-secure when called by PSCI library and this argument is
+retained for compatibility with BL31. The ``cpu_idx`` will correspond to the
+index returned by the ``plat_core_pos_by_mpidr()`` for ``mpidr`` of the CPU.
+
+Platform API
+~~~~~~~~~~~~
+
+The platform layer abstracts the platform-specific details from the generic
+PSCI library. The following platform APIs/macros must be defined by the EL3
+Runtime Software for integration with the PSCI library.
+
+The mandatory platform APIs are:
+
+-  plat_my_core_pos
+-  plat_core_pos_by_mpidr
+-  plat_get_syscnt_freq2
+-  plat_get_power_domain_tree_desc
+-  plat_setup_psci_ops
+-  plat_reset_handler
+-  plat_panic_handler
+-  plat_get_my_stack
+
+The mandatory platform macros are:
+
+-  PLATFORM_CORE_COUNT
+-  PLAT_MAX_PWR_LVL
+-  PLAT_NUM_PWR_DOMAINS
+-  CACHE_WRITEBACK_GRANULE
+-  PLAT_MAX_OFF_STATE
+-  PLAT_MAX_RET_STATE
+-  PLAT_MAX_PWR_LVL_STATES (optional)
+-  PLAT_PCPU_DATA_SIZE (optional)
+
+The details of these APIs/macros can be found in the :ref:`Porting Guide`.
+
+All platform specific operations for power management are done via
+``plat_psci_ops_t`` callbacks registered by the platform when
+``plat_setup_psci_ops()`` API is called. The description of each of
+the callbacks in ``plat_psci_ops_t`` can be found in PSCI section of the
+:ref:`Porting Guide`. If any these callbacks are not registered, then the
+PSCI API associated with that callback will not be supported by PSCI
+library.
+
+Secure payload power management callback
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+During PSCI power management operations, the EL3 Runtime Software may
+need to perform some bookkeeping, and PSCI library provides
+``spd_pm_ops_t`` callbacks for this purpose. These hooks must be
+populated and registered by using ``psci_register_spd_pm_hook()`` PSCI
+library interface.
+
+Typical bookkeeping during PSCI power management calls include save/restore
+of the EL3 Runtime Software context. Also if the EL3 Runtime Software makes
+use of secure interrupts, then these interrupts must also be managed
+appropriately during CPU power down/power up. Any secure interrupt targeted
+to the current CPU must be disabled or re-targeted to other running CPU prior
+to power down of the current CPU. During power up, these interrupt can be
+enabled/re-targeted back to the current CPU.
+
+.. code:: c
+
+        typedef struct spd_pm_ops {
+                void (*svc_on)(u_register_t target_cpu);
+                int32_t (*svc_off)(u_register_t __unused);
+                void (*svc_suspend)(u_register_t max_off_pwrlvl);
+                void (*svc_on_finish)(u_register_t __unused);
+                void (*svc_suspend_finish)(u_register_t max_off_pwrlvl);
+                int32_t (*svc_migrate)(u_register_t from_cpu, u_register_t to_cpu);
+                int32_t (*svc_migrate_info)(u_register_t *resident_cpu);
+                void (*svc_system_off)(void);
+                void (*svc_system_reset)(void);
+        } spd_pm_ops_t;
+
+A brief description of each callback is given below:
+
+-  svc_on, svc_off, svc_on_finish
+
+   The ``svc_on``, ``svc_off`` callbacks are called during PSCI_CPU_ON,
+   PSCI_CPU_OFF APIs respectively. The ``svc_on_finish`` is called when the
+   target CPU of PSCI_CPU_ON API powers up and executes the
+   ``psci_warmboot_entrypoint()`` PSCI library interface.
+
+-  svc_suspend, svc_suspend_finish
+
+   The ``svc_suspend`` callback is called during power down bu either
+   PSCI_SUSPEND or PSCI_SYSTEM_SUSPEND APIs. The ``svc_suspend_finish`` is
+   called when the CPU wakes up from suspend and executes the
+   ``psci_warmboot_entrypoint()`` PSCI library interface. The ``max_off_pwrlvl``
+   (first parameter) denotes the highest power domain level being powered down
+   to or woken up from suspend.
+
+-  svc_system_off, svc_system_reset
+
+   These callbacks are called during PSCI_SYSTEM_OFF and PSCI_SYSTEM_RESET
+   PSCI APIs respectively.
+
+-  svc_migrate_info
+
+   This callback is called in response to PSCI_MIGRATE_INFO_TYPE or
+   PSCI_MIGRATE_INFO_UP_CPU APIs. The return value of this callback must
+   correspond to the return value of PSCI_MIGRATE_INFO_TYPE API as described
+   in `PSCI spec`_. If the secure payload is a Uniprocessor (UP)
+   implementation, then it must update the mpidr of the CPU it is resident in
+   via ``resident_cpu`` (first argument). The updates to ``resident_cpu`` is
+   ignored if the secure payload is a multiprocessor (MP) implementation.
+
+-  svc_migrate
+
+   This callback is only relevant if the secure payload in EL3 Runtime
+   Software is a Uniprocessor (UP) implementation and supports migration from
+   the current CPU ``from_cpu`` (first argument) to another CPU ``to_cpu``
+   (second argument). This callback is called in response to PSCI_MIGRATE
+   API. This callback is never called if the secure payload is a
+   Multiprocessor (MP) implementation.
+
+CPU operations
+~~~~~~~~~~~~~~
+
+The CPU operations (cpu_ops) framework implement power down sequence specific
+to the CPU and the details of which can be found at
+:ref:`firmware_design_cpu_ops_fwk`. The TF-A tree implements the ``cpu_ops``
+for various supported CPUs and the EL3 Runtime Software needs to include the
+required ``cpu_ops`` in its build. The start and end of the ``cpu_ops``
+descriptors must be exported by the EL3 Runtime Software via the
+``__CPU_OPS_START__`` and ``__CPU_OPS_END__`` linker symbols.
+
+The ``cpu_ops`` descriptors also include reset sequences and may include errata
+workarounds for the CPU. The EL3 Runtime Software can choose to call this
+during cold/warm reset if it does not implement its own reset sequence/errata
+workarounds.

+EL3 Runtime Service Writer's Guide
+=====================================================
+
+Introduction
+------------
+
+This document describes how to add a runtime service to the EL3 Runtime
+Firmware component of Trusted Firmware-A (TF-A), BL31.
+
+Software executing in the normal world and in the trusted world at exception
+levels lower than EL3 will request runtime services using the Secure Monitor
+Call (SMC) instruction. These requests will follow the convention described in
+the SMC Calling Convention PDD (`SMCCC`_). The `SMCCC`_ assigns function
+identifiers to each SMC request and describes how arguments are passed and
+results are returned.
+
+SMC Functions are grouped together based on the implementor of the service, for
+example a subset of the Function IDs are designated as "OEM Calls" (see `SMCCC`_
+for full details). The EL3 runtime services framework in BL31 enables the
+independent implementation of services for each group, which are then compiled
+into the BL31 image. This simplifies the integration of common software from
+Arm to support `PSCI`_, Secure Monitor for a Trusted OS and SoC specific
+software. The common runtime services framework ensures that SMC Functions are
+dispatched to their respective service implementation - the
+:ref:`Firmware Design` document provides details of how this is achieved.
+
+The interface and operation of the runtime services depends heavily on the
+concepts and definitions described in the `SMCCC`_, in particular SMC Function
+IDs, Owning Entity Numbers (OEN), Fast and Standard calls, and the SMC32 and
+SMC64 calling conventions. Please refer to that document for a full explanation
+of these terms.
+
+Owning Entities, Call Types and Function IDs
+--------------------------------------------
+
+The SMC Function Identifier includes a OEN field. These values and their
+meaning are described in `SMCCC`_ and summarized in table 1 below. Some entities
+are allocated a range of of OENs. The OEN must be interpreted in conjunction
+with the SMC call type, which is either *Fast* or *Yielding*. Fast calls are
+uninterruptible whereas Yielding calls can be pre-empted. The majority of
+Owning Entities only have allocated ranges for Fast calls: Yielding calls are
+reserved exclusively for Trusted OS providers or for interoperability with
+legacy 32-bit software that predates the `SMCCC`_.
+
+::
+
+    Type       OEN     Service
+    Fast        0      Arm Architecture calls
+    Fast        1      CPU Service calls
+    Fast        2      SiP Service calls
+    Fast        3      OEM Service calls
+    Fast        4      Standard Service calls
+    Fast       5-47    Reserved for future use
+    Fast      48-49    Trusted Application calls
+    Fast      50-63    Trusted OS calls
+
+    Yielding   0- 1    Reserved for existing Armv7-A calls
+    Yielding   2-63    Trusted OS Standard Calls
+
+*Table 1: Service types and their corresponding Owning Entity Numbers*
+
+Each individual entity can allocate the valid identifiers within the entity
+range as they need - it is not necessary to coordinate with other entities of
+the same type. For example, two SoC providers can use the same Function ID
+within the SiP Service calls OEN range to mean different things - as these
+calls should be specific to the SoC. The Standard Runtime Calls OEN is used for
+services defined by Arm standards, such as `PSCI`_.
+
+The SMC Function ID also indicates whether the call has followed the SMC32
+calling convention, where all parameters are 32-bit, or the SMC64 calling
+convention, where the parameters are 64-bit. The framework identifies and
+rejects invalid calls that use the SMC64 calling convention but that originate
+from an AArch32 caller.
+
+The EL3 runtime services framework uses the call type and OEN to identify a
+specific handler for each SMC call, but it is expected that an individual
+handler will be responsible for all SMC Functions within a given service type.
+
+Getting started
+---------------
+
+TF-A has a ``services`` directory in the source tree under which
+each owning entity can place the implementation of its runtime service. The
+`PSCI`_ implementation is located here in the ``lib/psci`` directory.
+
+Runtime service sources will need to include the ``runtime_svc.h`` header file.
+
+Registering a runtime service
+-----------------------------
+
+A runtime service is registered using the ``DECLARE_RT_SVC()`` macro, specifying
+the name of the service, the range of OENs covered, the type of service and
+initialization and call handler functions.
+
+.. code:: c
+
+    #define DECLARE_RT_SVC(_name, _start, _end, _type, _setup, _smch)
+
+-  ``_name`` is used to identify the data structure declared by this macro, and
+   is also used for diagnostic purposes
+
+-  ``_start`` and ``_end`` values must be based on the ``OEN_*`` values defined in
+   ``smccc.h``
+
+-  ``_type`` must be one of ``SMC_TYPE_FAST`` or ``SMC_TYPE_YIELD``
+
+-  ``_setup`` is the initialization function with the ``rt_svc_init`` signature:
+
+   .. code:: c
+
+       typedef int32_t (*rt_svc_init)(void);
+
+-  ``_smch`` is the SMC handler function with the ``rt_svc_handle`` signature:
+
+   .. code:: c
+
+       typedef uintptr_t (*rt_svc_handle_t)(uint32_t smc_fid,
+                                         u_register_t x1, u_register_t x2,
+                                         u_register_t x3, u_register_t x4,
+                                         void *cookie,
+                                         void *handle,
+                                         u_register_t flags);
+
+Details of the requirements and behavior of the two callbacks is provided in
+the following sections.
+
+During initialization the services framework validates each declared service
+to ensure that the following conditions are met:
+
+#. The ``_start`` OEN is not greater than the ``_end`` OEN
+#. The ``_end`` OEN does not exceed the maximum OEN value (63)
+#. The ``_type`` is one of ``SMC_TYPE_FAST`` or ``SMC_TYPE_YIELD``
+#. ``_setup`` and ``_smch`` routines have been specified
+
+``std_svc_setup.c`` provides an example of registering a runtime service:
+
+.. code:: c
+
+    /* Register Standard Service Calls as runtime service */
+    DECLARE_RT_SVC(
+            std_svc,
+            OEN_STD_START,
+            OEN_STD_END,
+            SMC_TYPE_FAST,
+            std_svc_setup,
+            std_svc_smc_handler
+    );
+
+Initializing a runtime service
+------------------------------
+
+Runtime services are initialized once, during cold boot, by the primary CPU
+after platform and architectural initialization is complete. The framework
+performs basic validation of the declared service before calling
+the service initialization function (``_setup`` in the declaration). This
+function must carry out any essential EL3 initialization prior to receiving a
+SMC Function call via the handler function.
+
+On success, the initialization function must return ``0``. Any other return value
+will cause the framework to issue a diagnostic:
+
+::
+
+    Error initializing runtime service <name of the service>
+
+and then ignore the service - the system will continue to boot but SMC calls
+will not be passed to the service handler and instead return the *Unknown SMC
+Function ID* result ``0xFFFFFFFF``.
+
+If the system must not be allowed to proceed without the service, the
+initialization function must itself cause the firmware boot to be halted.
+
+If the service uses per-CPU data this must either be initialized for all CPUs
+during this call, or be done lazily when a CPU first issues an SMC call to that
+service.
+
+Handling runtime service requests
+---------------------------------
+
+SMC calls for a service are forwarded by the framework to the service's SMC
+handler function (``_smch`` in the service declaration). This function must have
+the following signature:
+
+.. code:: c
+
+    typedef uintptr_t (*rt_svc_handle_t)(uint32_t smc_fid,
+                                       u_register_t x1, u_register_t x2,
+                                       u_register_t x3, u_register_t x4,
+                                       void *cookie,
+                                       void *handle,
+                                       u_register_t flags);
+
+The handler is responsible for:
+
+#. Determining that ``smc_fid`` is a valid and supported SMC Function ID,
+   otherwise completing the request with the *Unknown SMC Function ID*:
+
+   .. code:: c
+
+       SMC_RET1(handle, SMC_UNK);
+
+#. Determining if the requested function is valid for the calling security
+   state. SMC Calls can be made from Non-secure, Secure or Realm worlds and
+   the framework will forward all calls to the service handler.
+
+   The ``flags`` parameter to this function indicates the caller security state
+   in bits 0 and 5. The ``is_caller_secure(flags)``, ``is_caller_non_secure(flags)``
+   and ``is_caller_realm(flags)`` helper functions can be used to determine whether
+   the caller's security state is Secure, Non-secure or Realm respectively.
+
+   If invalid, the request should be completed with:
+
+   .. code:: c
+
+       SMC_RET1(handle, SMC_UNK);
+
+#. Truncating parameters for calls made using the SMC32 calling convention.
+   Such calls can be determined by checking the CC field in bit[30] of the
+   ``smc_fid`` parameter, for example by using:
+
+   ::
+
+       if (GET_SMC_CC(smc_fid) == SMC_32) ...
+
+   For such calls, the upper bits of the parameters x1-x4 and the saved
+   parameters X5-X7 are UNDEFINED and must be explicitly ignored by the
+   handler. This can be done by truncating the values to a suitable 32-bit
+   integer type before use, for example by ensuring that functions defined
+   to handle individual SMC Functions use appropriate 32-bit parameters.
+
+#. Providing the service requested by the SMC Function, utilizing the
+   immediate parameters x1-x4 and/or the additional saved parameters X5-X7.
+   The latter can be retrieved using the ``SMC_GET_GP(handle, ref)`` function,
+   supplying the appropriate ``CTX_GPREG_Xn`` reference, e.g.
+
+   .. code:: c
+
+       uint64_t x6 = SMC_GET_GP(handle, CTX_GPREG_X6);
+
+#. Implementing the standard SMC32 Functions that provide information about
+   the implementation of the service. These are the Call Count, Implementor
+   UID and Revision Details for each service documented in section 6 of the
+   `SMCCC`_.
+
+   TF-A expects owning entities to follow this recommendation.
+
+#. Returning the result to the caller. Based on `SMCCC`_ spec, results are
+   returned in W0-W7(X0-X7) registers for SMC32(SMC64) calls from AArch64
+   state. Results are returned in R0-R7 registers for SMC32 calls from AArch32
+   state. The framework provides a family of macros to set the multi-register
+   return value and complete the handler:
+
+   .. code:: c
+
+       AArch64 state:
+
+       SMC_RET1(handle, x0);
+       SMC_RET2(handle, x0, x1);
+       SMC_RET3(handle, x0, x1, x2);
+       SMC_RET4(handle, x0, x1, x2, x3);
+       SMC_RET5(handle, x0, x1, x2, x3, x4);
+       SMC_RET6(handle, x0, x1, x2, x3, x4, x5);
+       SMC_RET7(handle, x0, x1, x2, x3, x4, x5, x6);
+       SMC_RET8(handle, x0, x1, x2, x3, x4, x5, x6, x7);
+
+       AArch32 state:
+
+       SMC_RET1(handle, r0);
+       SMC_RET2(handle, r0, r1);
+       SMC_RET3(handle, r0, r1, r2);
+       SMC_RET4(handle, r0, r1, r2, r3);
+       SMC_RET5(handle, r0, r1, r2, r3, r4);
+       SMC_RET6(handle, r0, r1, r2, r3, r4, r5);
+       SMC_RET7(handle, r0, r1, r2, r3, r4, r5, r6);
+       SMC_RET8(handle, r0, r1, r2, r3, r4, r5, r6, r7);
+
+The ``cookie`` parameter to the handler is reserved for future use and can be
+ignored. The ``handle`` is returned by the SMC handler - completion of the
+handler function must always be via one of the ``SMC_RETn()`` macros.
+
+.. note::
+   The PSCI and Test Secure-EL1 Payload Dispatcher services do not follow
+   all of the above requirements yet.
+
+Services that contain multiple sub-services
+-------------------------------------------
+
+It is possible that a single owning entity implements multiple sub-services. For
+example, the Standard calls service handles ``0x84000000``-``0x8400FFFF`` and
+``0xC4000000``-``0xC400FFFF`` functions. Within that range, the `PSCI`_ service
+handles the ``0x84000000``-``0x8400001F`` and ``0xC4000000``-``0xC400001F`` functions.
+In that respect, `PSCI`_ is a 'sub-service' of the Standard calls service. In
+future, there could be additional such sub-services in the Standard calls
+service which perform independent functions.
+
+In this situation it may be valuable to introduce a second level framework to
+enable independent implementation of sub-services. Such a framework might look
+very similar to the current runtime services framework, but using a different
+part of the SMC Function ID to identify the sub-service. TF-A does not provide
+such a framework at present.
+
+Secure-EL1 Payload Dispatcher service (SPD)
+-------------------------------------------
+
+Services that handle SMC Functions targeting a Trusted OS, Trusted Application,
+or other Secure-EL1 Payload are special. These services need to manage the
+Secure-EL1 context, provide the *Secure Monitor* functionality of switching
+between the normal and secure worlds, deliver SMC Calls through to Secure-EL1
+and generally manage the Secure-EL1 Payload through CPU power-state transitions.
+
+TODO: Provide details of the additional work required to implement a SPD and
+the BL31 support for these services. Or a reference to the document that will
+provide this information....

+Building Supporting Tools
+=========================
+
+.. note::
+
+    OpenSSL 3.0 is needed in order to build the tools. A custom installation
+    can be used if not updating the OpenSSL version on the OS. In order to do
+    this, use the ``OPENSSL_DIR`` variable after the ``make`` command to
+    indicate the location of the custom OpenSSL build. Then, to run the tools,
+    use the ``LD_LIBRARY_PATH`` to indicate the location of the built
+    libraries. More info about ``OPENSSL_DIR`` can be found at
+    :ref:`Build Options`.
+
+Building and using the FIP tool
+-------------------------------
+
+The following snippets build a :ref:`FIP<Image Terminology>` for the FVP
+platform. While it is not an intrinsic part of the FIP format, a BL33 image is
+required for these examples. For the purposes of experimentation, `Trusted
+Firmware-A Tests`_ (`tftf.bin``) may be used. Refer to to the `TFTF
+documentation`_ for instructions on building a TFTF binary.
+
+The TF-A build system provides the make target ``fip`` to create a FIP file
+for the specified platform using the FIP creation tool included in the TF-A
+project. Examples below show how to build a FIP file for FVP, packaging TF-A
+and BL33 images.
+
+For AArch64:
+
+.. code:: shell
+
+    make PLAT=fvp BL33=<path-to>/bl33.bin fip
+
+For AArch32:
+
+.. code:: shell
+
+    make PLAT=fvp ARCH=aarch32 AARCH32_SP=sp_min BL33=<path-to>/bl33.bin fip
+
+The resulting FIP may be found in:
+
+::
+
+    build/fvp/<build-type>/fip.bin
+
+For advanced operations on FIP files, it is also possible to independently build
+the tool and create or modify FIPs using this tool. To do this, follow these
+steps:
+
+It is recommended to remove old artifacts before building the tool:
+
+.. code:: shell
+
+    make -C tools/fiptool clean
+
+Build the tool:
+
+.. code:: shell
+
+    make [DEBUG=1] [V=1] fiptool
+
+The tool binary can be located in:
+
+::
+
+    ./tools/fiptool/fiptool
+
+Invoking the tool with ``help`` will print a help message with all available
+options.
+
+Example 1: create a new Firmware package ``fip.bin`` that contains BL2 and BL31:
+
+.. code:: shell
+
+    ./tools/fiptool/fiptool create \
+        --tb-fw build/<platform>/<build-type>/bl2.bin \
+        --soc-fw build/<platform>/<build-type>/bl31.bin \
+        fip.bin
+
+Example 2: view the contents of an existing Firmware package:
+
+.. code:: shell
+
+    ./tools/fiptool/fiptool info <path-to>/fip.bin
+
+Example 3: update the entries of an existing Firmware package:
+
+.. code:: shell
+
+    # Change the BL2 from Debug to Release version
+    ./tools/fiptool/fiptool update \
+        --tb-fw build/<platform>/release/bl2.bin \
+        build/<platform>/debug/fip.bin
+
+Example 4: unpack all entries from an existing Firmware package:
+
+.. code:: shell
+
+    # Images will be unpacked to the working directory
+    ./tools/fiptool/fiptool unpack <path-to>/fip.bin
+
+Example 5: remove an entry from an existing Firmware package:
+
+.. code:: shell
+
+    ./tools/fiptool/fiptool remove \
+        --tb-fw build/<platform>/debug/fip.bin
+
+Note that if the destination FIP file exists, the create, update and
+remove operations will automatically overwrite it.
+
+The unpack operation will fail if the images already exist at the
+destination. In that case, use -f or --force to continue.
+
+More information about FIP can be found in the :ref:`Firmware Design` document.
+
+.. _tools_build_cert_create:
+
+Building the Certificate Generation Tool
+----------------------------------------
+
+The ``cert_create`` tool is built as part of the TF-A build process when the
+``fip`` make target is specified and TBB is enabled (as described in the
+previous section), but it can also be built separately with the following
+command:
+
+.. code:: shell
+
+    make PLAT=<platform> [DEBUG=1] [V=1] certtool
+
+For platforms that require their own IDs in certificate files, the generic
+'cert_create' tool can be built with the following command. Note that the target
+platform must define its IDs within a ``platform_oid.h`` header file for the
+build to succeed.
+
+.. code:: shell
+
+    make PLAT=<platform> USE_TBBR_DEFS=0 [DEBUG=1] [V=1] certtool
+
+``DEBUG=1`` builds the tool in debug mode. ``V=1`` makes the build process more
+verbose. The following command should be used to obtain help about the tool:
+
+.. code:: shell
+
+    ./tools/cert_create/cert_create -h
+
+.. _tools_build_enctool:
+
+Building the Firmware Encryption Tool
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The ``encrypt_fw`` tool is built as part of the TF-A build process when the
+``fip`` make target is specified, DECRYPTION_SUPPORT and TBB are enabled, but
+it can also be built separately with the following command:
+
+.. code:: shell
+
+    make PLAT=<platform> [DEBUG=1] [V=1] enctool
+
+``DEBUG=1`` builds the tool in debug mode. ``V=1`` makes the build process more
+verbose. The following command should be used to obtain help about the tool:
+
+.. code:: shell
+
+    ./tools/encrypt_fw/encrypt_fw -h
+
+Note that the enctool in its current implementation only supports encryption
+key to be provided in plain format. A typical implementation can very well
+extend this tool to support custom techniques to protect encryption key.
+
+Also, a user may choose to provide encryption key or nonce as an input file
+via using ``cat <filename>`` instead of a hex string.

+Trusted Firmware-A (TF-A) provides a reference implementation of secure world
+software for `Armv7-A and Armv8-A`_, including a `Secure Monitor`_ executing
+at Exception Level 3 (EL3). It implements various Arm interface standards,
+such as:
+
+-  The `Power State Coordination Interface (PSCI)`_
+-  `Trusted Board Boot Requirements CLIENT (TBBR-CLIENT)`_
+-  `SMC Calling Convention`_
+-  `System Control and Management Interface (SCMI)`_
+-  `Software Delegated Exception Interface (SDEI)`_
+-  `PSA FW update specification`_
+
+Where possible, the code is designed for reuse or porting to other Armv7-A and
+Armv8-A model and hardware platforms.
+
+This release provides a suitable starting point for productization of secure
+world boot and runtime firmware, in either the AArch32 or AArch64 execution
+states.
+
+Users are encouraged to do their own security validation, including penetration
+testing, on any secure world code derived from TF-A.
+
+In collaboration with interested parties, we will continue to enhance |TF-A|
+with reference implementations of Arm standards to benefit developers working
+with Armv7-A and Armv8-A TrustZone technology.
+
+Getting Started
+---------------
+
+The |TF-A| documentation contains guidance for obtaining and building the
+software for existing, supported platforms, as well as supporting information
+for porting the software to a new platform.
+
+The **About** chapter gives a high-level overview of |TF-A| features as well as
+some information on the project and how it is organized.
+
+Refer to the documents in the **Getting Started** chapter for information about
+the prerequisites and requirements for building |TF-A|.
+
+The **Processes & Policies** chapter explains the project's release schedule
+and process, how security disclosures are handled, and the guidelines for
+contributing to the project (including the coding style).
+
+The **Components** chapter holds documents that explain specific components
+that make up the |TF-A| software, the :ref:`Exception Handling Framework`, for
+example.
+
+In the **System Design** chapter you will find documents that explain the
+design of portions of the software that involve more than one component, such
+as the :ref:`Trusted Board Boot` process.
+
+**Platform Ports** provides a list of the supported hardware and software-model
+platforms that are supported upstream in |TF-A|. Most of these platforms also
+have additional documentation that has been provided by the maintainers of the
+platform.
+
+The results of any performance evaluations are added to the
+**Performance & Testing** chapter.
+
+**Security Advisories** holds a list of documents relating to |CVE| entries that
+have previously been raised against the software.

+Performance Monitoring Unit
+===========================
+
+The Performance Monitoring Unit (PMU) allows recording of architectural and
+microarchitectural events for profiling purposes.
+
+This document gives an overview of the PMU counter configuration to assist with
+implementation and to complement the PMU security guidelines given in the
+:ref:`Secure Development Guidelines` document.
+
+.. note::
+   This section applies to Armv8-A implementations which have version 3
+   of the Performance Monitors Extension (PMUv3).
+
+PMU Counters
+------------
+
+The PMU makes 32 counters available at all privilege levels:
+
+-  31 programmable event counters: ``PMEVCNTR<n>``, where ``n`` is ``0`` to
+   ``30``.
+-  A dedicated cycle counter: ``PMCCNTR``.
+
+Architectural mappings
+~~~~~~~~~~~~~~~~~~~~~~
+
++--------------+---------+----------------------------+
+| Counters     | State   | System Register Name       |
++==============+=========+============================+
+|              | AArch64 | ``PMEVCNTR<n>_EL0[63*:0]`` |
+| Programmable +---------+----------------------------+
+|              | AArch32 | ``PMEVCNTR<n>[31:0]``      |
++--------------+---------+----------------------------+
+|              | AArch64 | ``PMCCNTR_EL0[63:0]``      |
+| Cycle        +---------+----------------------------+
+|              | AArch32 | ``PMCCNTR[63:0]``          |
++--------------+---------+----------------------------+
+
+.. note::
+   Bits [63:32] are only available if ARMv8.5-PMU is implemented. Refer to the
+   `Arm ARM`_ for a detailed description of ARMv8.5-PMU features.
+
+Configuring the PMU for counting events
+---------------------------------------
+
+Each programmable counter has an associated register, ``PMEVTYPER<n>`` which
+configures it. The cycle counter has the ``PMCCFILTR_EL0`` register, which has
+an identical function and bit field layout as ``PMEVTYPER<n>``. In addition,
+the counters are enabled (permitted to increment) via the ``PMCNTENSET`` and
+``PMCR`` registers. These can be accessed at all privilege levels.
+
+Architectural mappings

+| AArch64                     | AArch32                |

++-----------------------------+------------------------+
+
+.. note::
+   Bits [63:32] are reserved.
+
+Relevant register fields
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+For ``PMEVTYPER<n>_EL0``/``PMEVTYPER<n>`` and ``PMCCFILTR_EL0/PMCCFILTR``, the
+most important fields are:
+
+-  ``P``:
+
+   -  Bit 31.
+   -  If set to ``0``, will increment the associated ``PMEVCNTR<n>`` at EL1.
+
+-  ``NSK``:
+
+   -  Bit 29.
+   -  If equal to the ``P`` bit it enables the associated ``PMEVCNTR<n>`` at
+      Non-secure EL1.
+   -  Reserved if EL3 not implemented.
+
+-  ``NSH``:
+
+   -  Bit 27.
+   -  If set to ``1``, will increment the associated ``PMEVCNTR<n>`` at EL2.
+   -  Reserved if EL2 not implemented.
+
+-  ``SH``:
+
+   -  Bit 24.
+   -  If different to the ``NSH`` bit it enables the associated ``PMEVCNTR<n>``
+      at Secure EL2.
+   -  Reserved if Secure EL2 not implemented.
+
+-  ``M``:
+
+   -  Bit 26.
+   -  If equal to the ``P`` bit it enables the associated ``PMEVCNTR<n>`` at
+      EL3.
+
+-  ``evtCount[15:10]``:
+
+   -  Extension to ``evtCount[9:0]``. Reserved unless ARMv8.1-PMU implemented.
+
+-  ``evtCount[9:0]``:
+
+   -  The event number that the associated ``PMEVCNTR<n>`` will count.
+
+For ``PMCNTENSET_EL0``/``PMCNTENSET``, the most important fields are:
+
+-  ``P[30:0]``:
+
+   -  Setting bit ``P[n]`` to ``1`` enables counter ``PMEVCNTR<n>``.
+   -  The effects of ``PMEVTYPER<n>`` are applied on top of this.
+      In other words, the counter will not increment at any privilege level or
+      security state unless it is enabled here.
+
+-  ``C``:
+
+   -  Bit 31.
+   -  If set to ``1`` enables the cycle counter ``PMCCNTR``.
+
+For ``PMCR``/``PMCR_EL0``, the most important fields are:
+
+-  ``DP``:
+
+   -  Bit 5.
+   -  If set to ``1`` it disables the cycle counter ``PMCCNTR`` where event
+      counting (by ``PMEVCNTR<n>``) is prohibited (e.g. EL2 and the Secure
+      world).
+   -  If set to ``0``, ``PMCCNTR`` will not be affected by this bit and
+      therefore will be able to count where the programmable counters are
+      prohibited.
+
+-  ``E``:
+
+   -  Bit 0.
+   -  Enables/disables counting altogether.
+   -  The effects of ``PMCNTENSET`` and ``PMCR.DP`` are applied on top of this.
+      In other words, if this bit is ``0`` then no counters will increment
+      regardless of how the other PMU system registers or bit fields are
+      configured.

+PSCI Performance Measurements on Arm Juno Development Platform
+==============================================================
+
+This document summarises the findings of performance measurements of key
+operations in the Trusted Firmware-A Power State Coordination Interface (PSCI)
+implementation, using the in-built Performance Measurement Framework (PMF) and
+runtime instrumentation timestamps.
+
+Method
+------
+
+We used the `Juno R1 platform`_ for these tests, which has 4 x Cortex-A53 and 2
+x Cortex-A57 clusters running at the following frequencies:
+
++-----------------+--------------------+
+| Domain          | Frequency (MHz)    |
++=================+====================+
+| Cortex-A57      | 900 (nominal)      |
++-----------------+--------------------+
+| Cortex-A53      | 650 (underdrive)   |
++-----------------+--------------------+
+| AXI subsystem   | 533                |
++-----------------+--------------------+
+
+Juno supports CPU, cluster and system power down states, corresponding to power
+levels 0, 1 and 2 respectively. It does not support any retention states.
+
+We used the upstream `TF master as of 31/01/2017`_, building the platform using
+the ``ENABLE_RUNTIME_INSTRUMENTATION`` option:
+
+.. code:: shell
+
+    make PLAT=juno ENABLE_RUNTIME_INSTRUMENTATION=1 \
+        SCP_BL2=<path/to/scp-fw.bin>                \
+        BL33=<path/to/test-fw.bin>                  \
+        all fip
+
+When using the debug build of TF, there was no noticeable difference in the
+results.
+
+The tests are based on an ARM-internal test framework. The release build of this
+framework was used because the results in the debug build became skewed; the
+console output prevented some of the tests from executing in parallel.
+
+The tests consist of both parallel and sequential tests, which are broadly
+described as follows:
+
+- **Parallel Tests** This type of test powers on all the non-lead CPUs and
+  brings them and the lead CPU to a common synchronization point.  The lead CPU
+  then initiates the test on all CPUs in parallel.
+
+- **Sequential Tests** This type of test powers on each non-lead CPU in
+  sequence. The lead CPU initiates the test on a non-lead CPU then waits for the
+  test to complete before proceeding to the next non-lead CPU. The lead CPU then
+  executes the test on itself.
+
+In the results below, CPUs 0-3 refer to CPUs in the little cluster (A53) and
+CPUs 4-5 refer to CPUs in the big cluster (A57). In all cases CPU 4 is the lead
+CPU.
+
+``PSCI_ENTRY`` refers to the time taken from entering the TF PSCI implementation
+to the point the hardware enters the low power state (WFI). Referring to the TF
+runtime instrumentation points, this corresponds to:
+``(RT_INSTR_ENTER_HW_LOW_PWR - RT_INSTR_ENTER_PSCI)``.
+
+``PSCI_EXIT`` refers to the time taken from the point the hardware exits the low
+power state to exiting the TF PSCI implementation. This corresponds to:
+``(RT_INSTR_EXIT_PSCI - RT_INSTR_EXIT_HW_LOW_PWR)``.
+
+``CFLUSH_OVERHEAD`` refers to the part of ``PSCI_ENTRY`` taken to flush the
+caches. This corresponds to: ``(RT_INSTR_EXIT_CFLUSH - RT_INSTR_ENTER_CFLUSH)``.
+
+Note there is very little variance observed in the values given (~1us), although
+the values for each CPU are sometimes interchanged, depending on the order in
+which locks are acquired. Also, there is very little variance observed between
+executing the tests sequentially in a single boot or rebooting between tests.
+
+Given that runtime instrumentation using PMF is invasive, there is a small
+(unquantified) overhead on the results. PMF uses the generic counter for
+timestamps, which runs at 50MHz on Juno.

++-------+---------------------+--------------------+--------------------------+
+
+A large variance in ``PSCI_ENTRY`` and ``PSCI_EXIT`` times across CPUs is
+observed due to TF PSCI lock contention. In the worst case, CPU 3 has to wait
+for the 3 other CPUs in the cluster (0-2) to complete ``PSCI_ENTRY`` and release
+the lock before proceeding.
+
+The ``CFLUSH_OVERHEAD`` times for CPUs 3 and 5 are higher because they are the
+last CPUs in their respective clusters to power down, therefore both the L1 and
+L2 caches are flushed.
+
+The ``CFLUSH_OVERHEAD`` time for CPU 5 is a lot larger than that for CPU 3
+because the L2 cache size for the big cluster is lot larger (2MB) compared to
+the little cluster (1MB).

+
+There is no lock contention in TF generic code at power level 0 but the large
+variance in ``PSCI_ENTRY`` times across CPUs is due to lock contention in Juno
+platform code. The platform lock is used to mediate access to a single SCP
+communication channel. This is compounded by the SCP firmware waiting for each
+AP CPU to enter WFI before making the channel available to other CPUs, which
+effectively serializes the SCP power down commands from all CPUs.
+
+On platforms with a more efficient CPU power down mechanism, it should be
+possible to make the ``PSCI_ENTRY`` times smaller and consistent.
+
+The ``PSCI_EXIT`` times are consistent across all CPUs because TF does not
+require locks at power level 0.
+
+The ``CFLUSH_OVERHEAD`` times for all CPUs are small and consistent since only
+the cache associated with power level 0 is flushed (L1).

+
+The ``CFLUSH_OVERHEAD`` times for lead CPU 4 and all CPUs in the non-lead cluster
+are large because all other CPUs in the cluster are powered down during the
+test. The ``CPU_SUSPEND`` call powers down to the cluster level, requiring a
+flush of both L1 and L2 caches.
+
+The ``CFLUSH_OVERHEAD`` time for CPU 4 is a lot larger than those for the little
+CPUs because the L2 cache size for the big cluster is lot larger (2MB) compared
+to the little cluster (1MB).
+
+The ``PSCI_ENTRY`` and ``CFLUSH_OVERHEAD`` times for CPU 5 are low because lead
+CPU 4 continues to run while CPU 5 is suspended. Hence CPU 5 only powers down to
+level 0, which only requires L1 cache flush.

+
+Here the times are small and consistent since there is no contention and it is

+
+The ``PSCI_ENTRY`` times for CPUs in the big cluster are slightly smaller than
+for the CPUs in little cluster due to greater CPU performance.
+

+
+The ``CFLUSH_OVERHEAD`` times for all little CPUs are large because all other
+CPUs in that cluster are powerered down during the test. The ``CPU_OFF`` call
+powers down to the cluster level, requiring a flush of both L1 and L2 caches.
+
+The ``PSCI_ENTRY`` and ``CFLUSH_OVERHEAD`` times for CPU 5 are small because
+lead CPU 4 is running and CPU 5 only powers down to level 0, which only requires
+an L1 cache flush.
+
+The ``CFLUSH_OVERHEAD`` time for CPU 4 is a lot larger than those for the little
+CPUs because the L2 cache size for the big cluster is lot larger (2MB) compared
+to the little cluster (1MB).
+
+The ``PSCI_EXIT`` times for CPUs in the big cluster are slightly smaller than
+for CPUs in the little cluster due to greater CPU performance.  These times
+generally are greater than the ``PSCI_EXIT`` times in the ``CPU_SUSPEND`` tests
+because there is more code to execute in the "on finisher" compared to the
+"suspend finisher" (for example, GIC redistributor register programming).
+
+``PSCI_VERSION`` on all CPUs in parallel
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Since very little code is associated with ``PSCI_VERSION``, this test
+approximates the round trip latency for handling a fast SMC at EL3 in TF.

++-------+-------------------+
+
+The times for the big CPUs are less than the little CPUs due to greater CPU

+
+We suspect the time for lead CPU 4 is shorter than CPU 5 due to subtle cache
+effects, given that these measurements are at the nano-second level.

+Test Secure Payload (TSP) and Dispatcher (TSPD)
+===============================================
+
+Building the Test Secure Payload
+--------------------------------
+
+The TSP is coupled with a companion runtime service in the BL31 firmware,
+called the TSPD. Therefore, if you intend to use the TSP, the BL31 image
+must be recompiled as well. For more information on SPs and SPDs, see the
+:ref:`firmware_design_sel1_spd` section in the :ref:`Firmware Design`.
+
+First clean the TF-A build directory to get rid of any previous BL31 binary.
+Then to build the TSP image use:
+
+.. code:: shell
+
+    make PLAT=<platform> SPD=tspd all
+
+An additional boot loader binary file is created in the ``build`` directory:
+
+::
+
+    build/<platform>/<build-type>/bl32.bin

+Allwinner ARMv8 SoCs
+====================
+
+Trusted Firmware-A (TF-A) implements the EL3 firmware layer for Allwinner
+SoCs with ARMv8 cores. Only BL31 is used to provide proper EL3 setup and
+PSCI runtime services.
+
+Building TF-A
+-------------
+
+There is one build target per supported SoC:
+
++------+-------------------+
+| SoC  | TF-A build target |
++======+===================+
+| A64  | sun50i_a64        |
++------+-------------------+
+| H5   | sun50i_a64        |
++------+-------------------+
+| H6   | sun50i_h6         |
++------+-------------------+
+| H616 | sun50i_h616       |
++------+-------------------+
+| H313 | sun50i_h616       |
++------+-------------------+
+| R329 | sun50i_r329       |
++------+-------------------+
+
+To build with the default settings for a particular SoC:
+
+.. code:: shell
+
+    make CROSS_COMPILE=aarch64-linux-gnu- PLAT=<build target> DEBUG=1
+
+So for instance to build for a board with the Allwinner A64 SoC::
+
+    make CROSS_COMPILE=aarch64-linux-gnu- PLAT=sun50i_a64 DEBUG=1
+
+Platform-specific build options
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The default build options should generate a working firmware image. There are
+some build options that allow to fine-tune the firmware, or to disable support
+for optional features.
+
+-  ``SUNXI_PSCI_USE_NATIVE`` : Support direct control of the CPU cores powerdown
+   and powerup sequence by BL31. This requires either support for a code snippet
+   to be loaded into the ARISC SCP (A64, H5), or the power sequence control
+   registers to be programmed directly (H6, H616). This supports only basic
+   control, like core on/off and system off/reset.
+   This option defaults to 1. If an active SCP supporting the SCPI protocol
+   is detected at runtime, this control scheme will be ignored, and SCPI
+   will be used instead, unless support has been explicitly disabled.
+
+-  ``SUNXI_PSCI_USE_SCPI`` : Support control of the CPU cores powerdown and
+   powerup sequence by talking to the SCP processor via the SCPI protocol.
+   This allows more advanced power saving techniques, like suspend to RAM.
+   This option defaults to 1 on SoCs that feature an SCP. If no SCP firmware
+   using the SCPI protocol is detected, the native sequence will be used
+   instead. If both native and SCPI methods are included, SCPI will be favoured
+   if SCP support is detected.
+
+-  ``SUNXI_SETUP_REGULATORS`` : On SoCs that typically ship with a PMIC
+   power management controller, BL31 tries to set up all needed power rails,
+   programming them to their respective voltages. That allows bootloader
+   software like U-Boot to ignore power control via the PMIC.
+   This setting defaults to 1. In some situations that enables too many
+   regulators, or some regulators need to be enabled in a very specific
+   sequence. To avoid problems with those boards, ``SUNXI_SETUP_REGULATORS``
+   can bet set to ``0`` on the build command line, to skip the PMIC setup
+   entirely. Any bootloader or OS would need to setup the PMIC on its own then.
+
+Installation
+------------
+
+U-Boot's SPL acts as a loader, loading both BL31 and BL33 (typically U-Boot).
+Loading is done from SD card, eMMC or SPI flash, also via an USB debug
+interface (FEL).
+
+After building bl31.bin, the binary must be fed to the U-Boot build system
+to include it in the FIT image that the SPL loader will process.
+bl31.bin can be either copied (or sym-linked) into U-Boot's root directory,
+or the environment variable BL31 must contain the binary's path.
+See the respective `U-Boot documentation`_ for more details.
+
+.. _U-Boot documentation: https://gitlab.denx.de/u-boot/u-boot/-/blob/master/board/sunxi/README.sunxi64
+
+Memory layout
+-------------
+
+A64, H5 and H6 SoCs
+~~~~~~~~~~~~~~~~~~~
+
+BL31 lives in SRAM A2, which is documented to be accessible from secure
+world only. Since this SRAM region is very limited (48 KB), we take
+several measures to reduce memory consumption. One of them is to confine
+BL31 to only 28 bits of virtual address space, which reduces the number
+of required page tables (each occupying 4KB of memory).
+The mapping we use on those SoCs is as follows:
+
+::
+
+   0 64K         16M             1GB         1G+160M     physical address

+   0 64K         16M       160M    192M  256M             virtual address
+
+
+H616 SoC
+~~~~~~~~
+
+The H616 lacks the secure SRAM region present on the other SoCs, also
+lacks the "ARISC" management processor (SCP) we use. BL31 thus needs to
+run from DRAM, which prevents our compressed virtual memory map described
+above. Since running in DRAM also lifts the restriction of the limited
+SRAM size, we use the normal 1:1 mapping with 32 bits worth of virtual
+address space. So the virtual addresses used in BL31 match the physical
+addresses as presented above.
+
+Trusted OS dispatcher
+---------------------
+
+One can boot Trusted OS(OP-TEE OS, bl32 image) along side bl31 image on Allwinner A64.
+
+In order to include the 'opteed' dispatcher in the image, pass 'SPD=opteed' on the command line
+while compiling the bl31 image and make sure the loader (SPL) loads the Trusted OS binary to
+the beginning of DRAM (0x40000000).

+Arm Development Platform Build Options
+======================================
+
+Arm Platform Build Options
+--------------------------
+
+-  ``ARM_BL31_IN_DRAM``: Boolean option to select loading of BL31 in TZC secured
+   DRAM. By default, BL31 is in the secure SRAM. Set this flag to 1 to load
+   BL31 in TZC secured DRAM. If TSP is present, then setting this option also
+   sets the TSP location to DRAM and ignores the ``ARM_TSP_RAM_LOCATION`` build
+   flag.
+
+-  ``ARM_CONFIG_CNTACR``: boolean option to unlock access to the ``CNTBase<N>``
+   frame registers by setting the ``CNTCTLBase.CNTACR<N>`` register bits. The
+   frame number ``<N>`` is defined by ``PLAT_ARM_NSTIMER_FRAME_ID``, which
+   should match the frame used by the Non-Secure image (normally the Linux
+   kernel). Default is true (access to the frame is allowed).
+
+-  ``ARM_DISABLE_TRUSTED_WDOG``: boolean option to disable the Trusted Watchdog.
+   By default, Arm platforms use a watchdog to trigger a system reset in case
+   an error is encountered during the boot process (for example, when an image
+   could not be loaded or authenticated). The watchdog is enabled in the early
+   platform setup hook at BL1 and disabled in the BL1 prepare exit hook. The
+   Trusted Watchdog may be disabled at build time for testing or development
+   purposes.
+
+-  ``ARM_LINUX_KERNEL_AS_BL33``: The Linux kernel expects registers x0-x3 to
+   have specific values at boot. This boolean option allows the Trusted Firmware
+   to have a Linux kernel image as BL33 by preparing the registers to these
+   values before jumping to BL33. This option defaults to 0 (disabled). For
+   AArch64 ``RESET_TO_BL31`` and for AArch32 ``RESET_TO_SP_MIN`` must be 1 when
+   using it. If this option is set to 1, ``ARM_PRELOADED_DTB_BASE`` must be set
+   to the location of a device tree blob (DTB) already loaded in memory. The
+   Linux Image address must be specified using the ``PRELOADED_BL33_BASE``
+   option.
+
+-  ``ARM_PLAT_MT``: This flag determines whether the Arm platform layer has to
+   cater for the multi-threading ``MT`` bit when accessing MPIDR. When this flag
+   is set, the functions which deal with MPIDR assume that the ``MT`` bit in
+   MPIDR is set and access the bit-fields in MPIDR accordingly. Default value of
+   this flag is 0. Note that this option is not used on FVP platforms.
+
+-  ``ARM_RECOM_STATE_ID_ENC``: The PSCI1.0 specification recommends an encoding
+   for the construction of composite state-ID in the power-state parameter.
+   The existing PSCI clients currently do not support this encoding of
+   State-ID yet. Hence this flag is used to configure whether to use the
+   recommended State-ID encoding or not. The default value of this flag is 0,
+   in which case the platform is configured to expect NULL in the State-ID
+   field of power-state parameter.
+
+-  ``ARM_ROTPK_LOCATION``: used when ``TRUSTED_BOARD_BOOT=1``. It specifies the
+   location of the ROTPK hash returned by the function ``plat_get_rotpk_info()``
+   for Arm platforms. Depending on the selected option, the proper private key
+   must be specified using the ``ROT_KEY`` option when building the Trusted
+   Firmware. This private key will be used by the certificate generation tool
+   to sign the BL2 and Trusted Key certificates. Available options for
+   ``ARM_ROTPK_LOCATION`` are:
+
+   -  ``regs`` : return the ROTPK hash stored in the Trusted root-key storage
+      registers.
+   -  ``devel_rsa`` : return a development public key hash embedded in the BL1
+      and BL2 binaries. This hash has been obtained from the RSA public key
+      ``arm_rotpk_rsa.der``, located in ``plat/arm/board/common/rotpk``. To use
+      this option, ``arm_rotprivk_rsa.pem`` must be specified as ``ROT_KEY``
+      when creating the certificates.
+   -  ``devel_ecdsa`` : return a development public key hash embedded in the BL1
+      and BL2 binaries. This hash has been obtained from the ECDSA public key
+      ``arm_rotpk_ecdsa.der``, located in ``plat/arm/board/common/rotpk``. To
+      use this option, ``arm_rotprivk_ecdsa.pem`` must be specified as
+      ``ROT_KEY`` when creating the certificates.
+
+-  ``ARM_ROTPK_HASH``: used when ``ARM_ROTPK_LOCATION=devel_*``. Specifies the
+   location of the ROTPK hash. Not expected to be a build option. This defaults to
+   ``plat/arm/board/common/rotpk/*_sha256.bin`` depending on the specified algorithm.
+   Providing ``ROT_KEY`` enforces generation of the hash from the ``ROT_KEY`` and
+   overwrites the default hash file.
+
+-  ``ARM_TSP_RAM_LOCATION``: location of the TSP binary. Options:
+
+   -  ``tsram`` : Trusted SRAM (default option when TBB is not enabled)
+   -  ``tdram`` : Trusted DRAM (if available)
+   -  ``dram`` : Secure region in DRAM (default option when TBB is enabled,
+      configured by the TrustZone controller)
+
+-  ``ARM_XLAT_TABLES_LIB_V1``: boolean option to compile TF-A with version 1
+   of the translation tables library instead of version 2. It is set to 0 by
+   default, which selects version 2.
+
+-  ``ARM_CRYPTOCELL_INTEG`` : bool option to enable TF-A to invoke Arm®
+   TrustZone® CryptoCell functionality for Trusted Board Boot on capable Arm
+   platforms. If this option is specified, then the path to the CryptoCell
+   SBROM library must be specified via ``CCSBROM_LIB_PATH`` flag.
+
+-  ``ARM_ETHOSN_NPU_DRIVER``: boolean option to enable a SiP service that can
+   configure an Arm® Ethos™-N NPU. To use this service the target platform's
+   ``HW_CONFIG`` must include the device tree nodes for the NPU. Currently, only
+   the Arm Juno platform has this included in its ``HW_CONFIG`` and the platform
+   only loads the ``HW_CONFIG`` in AArch64 builds. Default is 0.
+
+-  ``ARM_SPMC_MANIFEST_DTS`` : path to an alternate manifest file used as the
+   SPMC Core manifest. Valid when ``SPD=spmd`` is selected.
+
+-  ``ARM_BL2_SP_LIST_DTS``: Path to DTS file snippet to override the hardcoded
+   SP nodes in tb_fw_config.
+
+-  ``OPTEE_SP_FW_CONFIG``: DTC build flag to include OP-TEE as SP in tb_fw_config
+   device tree. This flag is defined only when ``ARM_SPMC_MANIFEST_DTS`` manifest
+   file name contains pattern optee_sp.
+
+-  ``TS_SP_FW_CONFIG``: DTC build flag to include Trusted Services (Crypto and
+   internal-trusted-storage) as SP in tb_fw_config device tree.
+
+-  ``ARM_GPT_SUPPORT``: Enable GPT parser to get the entry address and length of
+   the various partitions present in the GPT image. This support is available
+   only for the BL2 component, and it is disabled by default.
+   The following diagram shows the view of the FIP partition inside the GPT

+
+Arm CSS Platform-Specific Build Options
+---------------------------------------
+
+-  ``CSS_DETECT_PRE_1_7_0_SCP``: Boolean flag to detect SCP version
+   incompatibility. Version 1.7.0 of the SCP firmware made a non-backwards
+   compatible change to the MTL protocol, used for AP/SCP communication.
+   TF-A no longer supports earlier SCP versions. If this option is set to 1
+   then TF-A will detect if an earlier version is in use. Default is 1.
+
+-  ``CSS_LOAD_SCP_IMAGES``: Boolean flag, which when set, adds SCP_BL2 and
+   SCP_BL2U to the FIP and FWU_FIP respectively, and enables them to be loaded
+   during boot. Default is 1.
+
+-  ``CSS_USE_SCMI_SDS_DRIVER``: Boolean flag which selects SCMI/SDS drivers
+   instead of SCPI/BOM driver for communicating with the SCP during power
+   management operations and for SCP RAM Firmware transfer. If this option
+   is set to 1, then SCMI/SDS drivers will be used. Default is 0.
+
+ - ``CSS_SGI_CHIP_COUNT``: Configures the number of chips on a SGI/RD platform
+   which supports multi-chip operation. If ``CSS_SGI_CHIP_COUNT`` is set to any
+   valid value greater than 1, the platform code performs required configuration
+   to support multi-chip operation.
+
+- ``CSS_SGI_PLATFORM_VARIANT``: Selects the variant of a SGI/RD platform. A
+    particular SGI/RD platform may have multiple variants which may differ in
+    core count, cluster count or other peripherals. This build option is used
+    to select the appropriate platform variant for the build. The range of
+    valid values is platform specific.
+
+- ``CSS_SYSTEM_GRACEFUL_RESET``: Build option to enable graceful powerdown of
+   CPU core on reset. This build option can be used on CSS platforms that
+   require all the CPUs to execute the CPU specific power down sequence to
+   complete a warm reboot sequence in which only the CPUs are power cycled.

+Arm FPGA Platform
+=================
+
+This platform supports FPGA images used internally in Arm Ltd., for
+testing and bringup of new cores. With that focus, peripheral support is
+minimal: there is no mass storage or display output, for instance. Also
+this port ignores any power management features of the platform.
+Some interconnect setup is done internally by the platform, so the TF-A code
+just needs to setup UART and GIC.
+
+The FPGA platform requires to pass on a DTB for the non-secure payload
+(mostly Linux), so we let TF-A use information from the DTB for dynamic
+configuration: the UART and GIC base addresses are read from there.
+
+As a result this port is a fairly generic BL31-only port, which can serve
+as a template for a minimal new (and possibly DT-based) platform port.
+
+The aim of this port is to support as many FPGA images as possible with
+a single build. Image specific data must be described in the DTB or should
+be auto-detected at runtime.
+
+As the number and topology layout of the CPU cores differs significantly
+across the various images, this is detected at runtime by BL31.
+The /cpus node in the DT will be added and filled accordingly, as long as
+it does not exist already.
+
+Platform-specific build options
+-------------------------------
+
+-  ``SUPPORT_UNKNOWN_MPID`` : Boolean option to allow unknown MPIDR registers.
+   Normally TF-A panics if it encounters a MPID value not matched to its
+   internal list, but for new or experimental cores this creates a lot of
+   churn. With this option, the code will fall back to some basic CPU support
+   code (only architectural system registers, and no errata).
+   Default value of this flag is 1.
+
+-  ``PRELOADED_BL33_BASE`` : Physical address of the BL33 non-secure payload.
+   It must have been loaded into DRAM already, typically this is done by
+   the script that also loads BL31 and the DTB.
+   It defaults to 0x80080000, which is the traditional load address for an
+   arm64 Linux kernel.
+
+-  ``FPGA_PRELOADED_DTB_BASE`` : Physical address of the flattened device
+   tree blob (DTB). This DT will be used by TF-A for dynamic configuration,
+   so it must describe at least the UART and a GICv3 interrupt controller.
+   The DT gets amended by the code, to potentially add a command line and
+   fill the CPU topology nodes. It will also be passed on to BL33, by
+   putting its address into the x0 register before jumping to the entry
+   point (following the Linux kernel boot protocol).
+   It defaults to 0x80070000, which is 64KB before the BL33 load address.
+
+-  ``FPGA_PRELOADED_CMD_LINE`` : Physical address of the command line to
+   put into the devicetree blob. Due to the lack of a proper bootloader,
+   a command line can be put somewhere into memory, so that BL31 will
+   detect it and copy it into the DTB passed on to BL33.
+   To avoid random garbage, there needs to be a "CMD:" signature before the
+   actual command line.
+   Defaults to 0x1000, which is normally in the "ROM" space of the typical
+   FPGA image (which can be written by the FPGA payload uploader, but is
+   read-only to the CPU). The FPGA payload tool should be given a text file
+   containing the desired command line, prefixed by the "CMD:" signature.
+
+Building the TF-A image
+-----------------------
+
+   .. code:: shell
+
+       make PLAT=arm_fgpa DEBUG=1
+
+   This will use the default load addresses as described above. When those
+   addresses need to differ for a certain setup, they can be passed on the
+   make command line:
+
+   .. code:: shell
+
+       make PLAT=arm_fgpa DEBUG=1 PRELOADED_BL33_BASE=0x80200000 FPGA_PRELOADED_DTB_BASE=0x80180000 bl31
+
+Running the TF-A image
+----------------------
+
+After building TF-A, the actual TF-A code will be located in ``bl31.bin`` in
+the build directory.
+Additionally there is a ``bl31.axf`` ELF file, which contains BL31, as well
+as some simple ROM trampoline code (required by the Arm FPGA boot flow) and
+a generic DTB to support most of the FPGA images. This can be simply handed
+over to the FPGA payload uploader, which will take care of loading the
+components at their respective load addresses. In addition to this file
+you need at least a BL33 payload (typically a Linux kernel image), optionally
+a Linux initrd image file and possibly a command line:
+
+   .. code:: shell
+
+       fpga-run ... -m bl31.axf -l auto -m Image -l 0x80080000 -m initrd.gz -l 0x84000000 -m cmdline.txt -l 0x1000

+Corstone1000 Platform
+==========================
+
+Some of the features of the Corstone1000 platform referenced in TF-A include:
+
+- Cortex-A35 application processor (64-bit mode)
+- Secure Enclave
+- GIC-400
+- Trusted Board Boot
+
+Boot Sequence
+-------------
+
+The board boot relies on CoT (chain of trust). The trusted-firmware-a
+BL2 is extracted from the FIP and verified by the Secure Enclave
+processor. BL2 verification relies on the signature area at the
+beginning of the BL2 image. This area is needed by the SecureEnclave
+bootloader.
+
+Then, the application processor is released from reset and starts by
+executing BL2.
+
+BL2 performs the actions described in the trusted-firmware-a TBB design
+document.

+   support these legacy GIC configurations.
+
+The *Foundation* and *Base* FVPs can be downloaded free of charge. See the `Arm
+FVP website`_. The Cortex-A models listed above are also available to download
+from `Arm's website`_.
+
+.. note::
+   The build numbers quoted above are those reported by launching the FVP
+   with the ``--version`` parameter.
+
+.. note::
+   Linaro provides a ramdisk image in prebuilt FVP configurations and full
+   file systems that can be downloaded separately. To run an FVP with a virtio
+   file system image an additional FVP configuration option
+   ``-C bp.virtioblockdevice.image_path="<path-to>/<file-system-image>`` can be
+   used.
+
+.. note::
+   The software will not work on Version 1.0 of the Foundation FVP.
+   The commands below would report an ``unhandled argument`` error in this case.
+
+.. note::
+   FVPs can be launched with ``--cadi-server`` option such that a
+   CADI-compliant debugger (for example, Arm DS-5) can connect to and control
+   its execution.
+
+.. warning::
+   Since FVP model Version 11.0 Build 11.0.34 and Version 8.5 Build 0.8.5202
+   the internal synchronisation timings changed compared to older versions of

+   required to match the run time characteristics of the older versions.
+
+All the above platforms have been tested with `Linaro Release 20.01`_.
+
+.. _build_options_arm_fvp_platform:
+
+Arm FVP Platform Specific Build Options
+---------------------------------------
+
+-  ``FVP_CLUSTER_COUNT`` : Configures the cluster count to be used to
+   build the topology tree within TF-A. By default TF-A is configured for dual
+   cluster topology and this option can be used to override the default value.
+
+-  ``FVP_INTERCONNECT_DRIVER``: Selects the interconnect driver to be built. The
+   default interconnect driver depends on the value of ``FVP_CLUSTER_COUNT`` as
+   explained in the options below:
+
+   -  ``FVP_CCI`` : The CCI driver is selected. This is the default
+      if 0 < ``FVP_CLUSTER_COUNT`` <= 2.
+   -  ``FVP_CCN`` : The CCN driver is selected. This is the default
+      if ``FVP_CLUSTER_COUNT`` > 2.
+
+-  ``FVP_MAX_CPUS_PER_CLUSTER``: Sets the maximum number of CPUs implemented in
+   a single cluster.  This option defaults to 4.
+
+-  ``FVP_MAX_PE_PER_CPU``: Sets the maximum number of PEs implemented on any CPU
+   in the system. This option defaults to 1. Note that the build option
+   ``ARM_PLAT_MT`` doesn't have any effect on FVP platforms.
+
+-  ``FVP_USE_GIC_DRIVER`` : Selects the GIC driver to be built. Options:
+
+   -  ``FVP_GICV2`` : The GICv2 only driver is selected
+   -  ``FVP_GICV3`` : The GICv3 only driver is selected (default option)
+
+-  ``FVP_HW_CONFIG_DTS`` : Specify the path to the DTS file to be compiled
+   to DTB and packaged in FIP as the HW_CONFIG. See :ref:`Firmware Design` for
+   details on HW_CONFIG. By default, this is initialized to a sensible DTS
+   file in ``fdts/`` folder depending on other build options. But some cases,
+   like shifted affinity format for MPIDR, cannot be detected at build time
+   and this option is needed to specify the appropriate DTS file.
+
+-  ``FVP_HW_CONFIG`` : Specify the path to the HW_CONFIG blob to be packaged in
+   FIP. See :ref:`Firmware Design` for details on HW_CONFIG. This option is
+   similar to the ``FVP_HW_CONFIG_DTS`` option, but it directly specifies the
+   HW_CONFIG blob instead of the DTS file. This option is useful to override
+   the default HW_CONFIG selected by the build system.
+
+-  ``FVP_GICR_REGION_PROTECTION``: Mark the redistributor pages of
+   inactive/fused CPU cores as read-only. The default value of this option
+   is ``0``, which means the redistributor pages of all CPU cores are marked
+   as read and write.
+
+Booting Firmware Update images
+------------------------------
+
+When Firmware Update (FWU) is enabled there are at least 2 new images
+that have to be loaded, the Non-Secure FWU ROM (NS-BL1U), and the
+FWU FIP.
+
+The additional fip images must be loaded with:
+
+::
+
+    --data cluster0.cpu0="<path_to>/ns_bl1u.bin"@0x0beb8000	[ns_bl1u_base_address]
+    --data cluster0.cpu0="<path_to>/fwu_fip.bin"@0x08400000	[ns_bl2u_base_address]
+
+The address ns_bl1u_base_address is the value of NS_BL1U_BASE.
+In the same way, the address ns_bl2u_base_address is the value of
+NS_BL2U_BASE.
+
+Booting an EL3 payload
+----------------------
+
+The EL3 payloads boot flow requires the CPU's mailbox to be cleared at reset for
+the secondary CPUs holding pen to work properly. Unfortunately, its reset value
+is undefined on the FVP platform and the FVP platform code doesn't clear it.
+Therefore, one must modify the way the model is normally invoked in order to
+clear the mailbox at start-up.
+
+One way to do that is to create an 8-byte file containing all zero bytes using
+the following command:
+
+.. code:: shell
+
+    dd if=/dev/zero of=mailbox.dat bs=1 count=8
+
+and pre-load it into the FVP memory at the mailbox address (i.e. ``0x04000000``)
+using the following model parameters:
+
+::

+
+To provide the model with the EL3 payload image, the following methods may be
+used:
+
+#. If the EL3 payload is able to execute in place, it may be programmed into
+   flash memory. On Base Cortex and AEM FVPs, the following model parameter
+   loads it at the base address of the NOR FLASH1 (the NOR FLASH0 is already
+   used for the FIP):
+
+   ::
+
+       -C bp.flashloader1.fname="<path-to>/<el3-payload>"
+
+   On Foundation FVP, there is no flash loader component and the EL3 payload
+   may be programmed anywhere in flash using method 3 below.
+
+#. When using the ``SPIN_ON_BL1_EXIT=1`` loading method, the following DS-5
+   command may be used to load the EL3 payload ELF image over JTAG:
+
+   ::
+
+       load <path-to>/el3-payload.elf
+
+#. The EL3 payload may be pre-loaded in volatile memory using the following
+   model parameters:
+
+   ::
+
+       --data cluster0.cpu0="<path-to>/el3-payload>"@address   [Base FVPs]
+       --data="<path-to>/<el3-payload>"@address                [Foundation FVP]
+
+   The address provided to the FVP must match the ``EL3_PAYLOAD_BASE`` address
+   used when building TF-A.
+
+Booting a preloaded kernel image (Base FVP)
+-------------------------------------------
+
+The following example uses a simplified boot flow by directly jumping from the
+TF-A to the Linux kernel, which will use a ramdisk as filesystem. This can be
+useful if both the kernel and the device tree blob (DTB) are already present in
+memory (like in FVP).
+
+For example, if the kernel is loaded at ``0x80080000`` and the DTB is loaded at
+address ``0x82000000``, the firmware can be built like this:
+
+.. code:: shell
+
+    CROSS_COMPILE=aarch64-none-elf-  \
+    make PLAT=fvp DEBUG=1             \
+    RESET_TO_BL31=1                   \
+    ARM_LINUX_KERNEL_AS_BL33=1        \
+    PRELOADED_BL33_BASE=0x80080000    \
+    ARM_PRELOADED_DTB_BASE=0x82000000 \
+    all fip
+
+Now, it is needed to modify the DTB so that the kernel knows the address of the
+ramdisk. The following script generates a patched DTB from the provided one,
+assuming that the ramdisk is loaded at address ``0x84000000``. Note that this
+script assumes that the user is using a ramdisk image prepared for U-Boot, like
+the ones provided by Linaro. If using a ramdisk without this header,the ``0x40``
+offset in ``INITRD_START`` has to be removed.
+
+.. code:: bash
+
+    #!/bin/bash
+
+    # Path to the input DTB
+    KERNEL_DTB=<path-to>/<fdt>
+    # Path to the output DTB
+    PATCHED_KERNEL_DTB=<path-to>/<patched-fdt>
+    # Base address of the ramdisk
+    INITRD_BASE=0x84000000
+    # Path to the ramdisk
+    INITRD=<path-to>/<ramdisk.img>
+
+    # Skip uboot header (64 bytes)
+    INITRD_START=$(printf "0x%x" $((${INITRD_BASE} + 0x40)) )
+    INITRD_SIZE=$(stat -Lc %s ${INITRD})
+    INITRD_END=$(printf "0x%x" $((${INITRD_BASE} + ${INITRD_SIZE})) )
+
+    CHOSEN_NODE=$(echo                                        \
+    "/ {                                                      \
+            chosen {                                          \
+                    linux,initrd-start = <${INITRD_START}>;   \
+                    linux,initrd-end = <${INITRD_END}>;       \
+            };                                                \
+    };")
+
+    echo $(dtc -O dts -I dtb ${KERNEL_DTB}) ${CHOSEN_NODE} |  \
+            dtc -O dtb -o ${PATCHED_KERNEL_DTB} -
+
+And the FVP binary can be run with the following command:
+
+.. code:: shell

+
+Obtaining the Flattened Device Trees
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Depending on the FVP configuration and Linux configuration used, different
+FDT files are required. FDT source files for the Foundation and Base FVPs can
+be found in the TF-A source directory under ``fdts/``. The Foundation FVP has
+a subset of the Base FVP components. For example, the Foundation FVP lacks
+CLCD and MMC support, and has only one CPU cluster.
+
+.. note::
+   It is not recommended to use the FDTs built along the kernel because not
+   all FDTs are available from there.
+
+The dynamic configuration capability is enabled in the firmware for FVPs.
+This means that the firmware can authenticate and load the FDT if present in
+FIP. A default FDT is packaged into FIP during the build based on
+the build configuration. This can be overridden by using the ``FVP_HW_CONFIG``
+or ``FVP_HW_CONFIG_DTS`` build options (refer to
+:ref:`build_options_arm_fvp_platform` for details on the options).

+
+Notes:
+
+-  BL1 is loaded at the start of the Trusted ROM.
+-  The Firmware Image Package is loaded at the start of NOR FLASH0.
+-  The firmware loads the FDT packaged in FIP to the DRAM. The FDT load address
+   is specified via the ``load-address`` property in the ``hw-config`` node of
+   `FW_CONFIG for FVP`_.
+-  The default use-case for the Foundation FVP is to use the ``--gicv3`` option
+   and enable the GICv3 device in the model. Note that without this option,
+   the Foundation FVP defaults to legacy (Versatile Express) memory map which
+   is not supported by TF-A.
+-  In order for TF-A to run correctly on the Foundation FVP, the architecture
+   versions must match. The Foundation FVP defaults to the highest v8.x
+   version it supports but the default build for TF-A is for v8.0. To avoid
+   issues either start the Foundation FVP to use v8.0 architecture using the
+   ``--arm-v8.0`` option, or build TF-A with an appropriate value for
+   ``ARM_ARCH_MINOR``.

+-  Position Independent Executable (PIE) support is enabled in this

+   ``--data="<path-to><bl31|bl32|bl33-binary>"@<base-address-of-binary>``
+   parameter is needed to load the individual bootloader images in memory.
+   BL32 image is only needed if BL31 has been built to expect a Secure-EL1

+Arm Juno Development Platform
+=============================
+
+Platform-specific build options
+-------------------------------
+
+-  ``JUNO_TZMP1`` : Boolean option to configure Juno to be used for TrustZone
+   Media Protection (TZ-MP1). Default value of this flag is 0.
+
+Running software on Juno
+------------------------
+
+This version of TF-A has been tested on variants r0, r1 and r2 of Juno.
+
+To run TF-A on Juno, you need to first prepare an SD card with Juno software
+stack that includes TF-A. This version of TF-A is tested with pre-built
+`Linaro release software stack`_ version 20.01. You can alternatively
+build the software stack yourself by following the
+`Juno platform software user guide`_. Once you prepare the software stack
+on an SD card, you can replace the ``bl1.bin`` and ``fip.bin``
+binaries in the ``SOFTWARE/`` directory with custom built TF-A binaries.
+
+Preparing TF-A images
+---------------------
+
+This section provides Juno and FVP specific instructions to build Trusted
+Firmware, obtain the additional required firmware, and pack it all together in
+a single FIP binary. It assumes that a Linaro release software stack has been
+installed.
+
+.. note::
+   Pre-built binaries for AArch32 are available from Linaro Release 16.12
+   onwards. Before that release, pre-built binaries are only available for
+   AArch64.
+
+.. warning::
+   Follow the full instructions for one platform before switching to a
+   different one. Mixing instructions for different platforms may result in
+   corrupted binaries.
+
+.. warning::
+   The uboot image downloaded by the Linaro workspace script does not always
+   match the uboot image packaged as BL33 in the corresponding fip file. It is
+   recommended to use the version that is packaged in the fip file using the
+   instructions below.
+
+.. note::
+   For the FVP, the kernel FDT is packaged in FIP during build and loaded
+   by the firmware at runtime.
+
+#. Clean the working directory
+
+   .. code:: shell
+
+       make realclean
+
+#. Obtain SCP binaries (Juno)
+
+   This version of TF-A is tested with SCP version 2.8.0 on Juno. You can
+   download pre-built SCP binaries (``scp_bl1.bin`` and ``scp_bl2.bin``)
+   from `TF-A downloads page`_. Alternatively, you can `build
+   the binaries from source`_.
+
+#. Obtain BL33 (all platforms)
+
+   Use the fiptool to extract the BL33 image from the FIP
+   package included in the Linaro release:
+
+   .. code:: shell
+
+       # Build the fiptool
+       make [DEBUG=1] [V=1] fiptool
+
+       # Unpack firmware images from Linaro FIP
+       ./tools/fiptool/fiptool unpack <path-to-linaro-release>/[SOFTWARE]/fip.bin
+
+   The unpack operation will result in a set of binary images extracted to the
+   current working directory. BL33 corresponds to ``nt-fw.bin``.
+
+   .. note::
+      The fiptool will complain if the images to be unpacked already
+      exist in the current directory. If that is the case, either delete those
+      files or use the ``--force`` option to overwrite.
+
+   .. note::
+      For AArch32, the instructions below assume that nt-fw.bin is a
+      normal world boot loader that supports AArch32.
+
+#. Build TF-A images and create a new FIP for FVP
+
+   .. code:: shell
+
+       # AArch64
+       make PLAT=fvp BL33=nt-fw.bin all fip
+
+       # AArch32
+       make PLAT=fvp ARCH=aarch32 AARCH32_SP=sp_min BL33=nt-fw.bin all fip
+
+#. Build TF-A images and create a new FIP for Juno
+
+   For AArch64:
+
+   Building for AArch64 on Juno simply requires the addition of ``SCP_BL2``
+   as a build parameter.
+
+   .. code:: shell
+
+       make PLAT=juno BL33=nt-fw.bin SCP_BL2=scp_bl2.bin all fip
+
+   For AArch32:
+
+   Hardware restrictions on Juno prevent cold reset into AArch32 execution mode,
+   therefore BL1 and BL2 must be compiled for AArch64, and BL32 is compiled
+   separately for AArch32.
+
+   -  Before building BL32, the environment variable ``CROSS_COMPILE`` must point
+      to the AArch32 Linaro cross compiler.
+
+      .. code:: shell
+
+          export CROSS_COMPILE=<path-to-aarch32-gcc>/bin/arm-linux-gnueabihf-
+
+   -  Build BL32 in AArch32.
+
+      .. code:: shell
+
+          make ARCH=aarch32 PLAT=juno AARCH32_SP=sp_min \
+          RESET_TO_SP_MIN=1 JUNO_AARCH32_EL3_RUNTIME=1 bl32
+
+   -  Save ``bl32.bin`` to a temporary location and clean the build products.
+
+      ::
+
+          cp <path-to-build>/bl32.bin <path-to-temporary>
+          make realclean
+
+   -  Before building BL1 and BL2, the environment variable ``CROSS_COMPILE``
+      must point to the AArch64 Linaro cross compiler.
+
+      .. code:: shell
+
+          export CROSS_COMPILE=<path-to-aarch64-gcc>/bin/aarch64-none-elf-
+
+   -  The following parameters should be used to build BL1 and BL2 in AArch64
+      and point to the BL32 file.
+
+      .. code:: shell
+
+          make ARCH=aarch64 PLAT=juno JUNO_AARCH32_EL3_RUNTIME=1 \
+          BL33=nt-fw.bin SCP_BL2=scp_bl2.bin \
+          BL32=<path-to-temporary>/bl32.bin all fip
+
+The resulting BL1 and FIP images may be found in:
+
+::
+
+    # Juno
+    ./build/juno/release/bl1.bin
+    ./build/juno/release/fip.bin
+
+    # FVP
+    ./build/fvp/release/bl1.bin
+    ./build/fvp/release/fip.bin
+
+After building TF-A, the files ``bl1.bin``, ``fip.bin`` and ``scp_bl1.bin``
+need to be copied to the ``SOFTWARE/`` directory on the Juno SD card.
+
+Booting Firmware Update images
+------------------------------
+
+The new images must be programmed in flash memory by adding
+an entry in the ``SITE1/HBI0262x/images.txt`` configuration file
+on the Juno SD card (where ``x`` depends on the revision of the Juno board).
+Refer to the `Juno Getting Started Guide`_, section 2.3 "Flash memory
+programming" for more information. User should ensure these do not
+overlap with any other entries in the file.
+
+::
+
+        NOR10UPDATE: AUTO                       ;Image Update:NONE/AUTO/FORCE
+        NOR10ADDRESS: 0x00400000                ;Image Flash Address [ns_bl2u_base_address]
+        NOR10FILE: \SOFTWARE\fwu_fip.bin        ;Image File Name
+        NOR10LOAD: 00000000                     ;Image Load Address
+        NOR10ENTRY: 00000000                    ;Image Entry Point
+
+        NOR11UPDATE: AUTO                       ;Image Update:NONE/AUTO/FORCE
+        NOR11ADDRESS: 0x03EB8000                ;Image Flash Address [ns_bl1u_base_address]
+        NOR11FILE: \SOFTWARE\ns_bl1u.bin        ;Image File Name
+        NOR11LOAD: 00000000                     ;Image Load Address
+
+The address ns_bl1u_base_address is the value of NS_BL1U_BASE - 0x8000000.
+In the same way, the address ns_bl2u_base_address is the value of
+NS_BL2U_BASE - 0x8000000.
+
+.. _plat_juno_booting_el3_payload:
+
+Booting an EL3 payload
+----------------------
+
+If the EL3 payload is able to execute in place, it may be programmed in flash
+memory by adding an entry in the ``SITE1/HBI0262x/images.txt`` configuration file
+on the Juno SD card (where ``x`` depends on the revision of the Juno board).
+Refer to the `Juno Getting Started Guide`_, section 2.3 "Flash memory
+programming" for more information.
+
+Alternatively, the same DS-5 command mentioned in the FVP section above can
+be used to load the EL3 payload's ELF file over JTAG on Juno.
+
+For more information on EL3 payloads in general, see
+:ref:`alt_boot_flows_el3_payload`.
+
+Booting a preloaded kernel image
+--------------------------------
+
+The Trusted Firmware must be compiled in a similar way as for FVP explained
+above. The process to load binaries to memory is the one explained in
+`plat_juno_booting_el3_payload`_.
+
+Testing System Suspend
+----------------------
+
+The SYSTEM SUSPEND is a PSCI API which can be used to implement system suspend
+to RAM. For more details refer to section 5.16 of `PSCI`_. To test system suspend
+on Juno, at the linux shell prompt, issue the following command:
+
+.. code:: shell
+
+    echo +10 > /sys/class/rtc/rtc0/wakealarm
+    echo -n mem > /sys/power/state
+
+The Juno board should suspend to RAM and then wakeup after 10 seconds due to
+wakeup interrupt from RTC.

+Morello Platform
+================
+
+Morello is an ARMv8-A platform that implements the capability architecture extension.
+The platform port present at `site <https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git>`_
+provides ARMv8-A architecture enablement.
+
+Capability architecture specific changes will be added `here <https://git.morello-project.org/morello>`_
+
+Further information on Morello Platform is available at `info <https://developer.arm.com/architectures/cpu-architecture/a-profile/morello>`_
+
+Boot Sequence
+-------------
+
+The execution begins from SCP_BL1 which loads the SCP_BL2 and starts its
+execution. SCP_BL2 powers up the AP which starts execution at AP_BL31. The AP
+then continues executing and hands off execution to Non-secure world (UEFI).
+
+Build Procedure (TF-A only)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+-  Obtain arm `toolchain <https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-a/downloads>`_.
+   Set the CROSS_COMPILE environment variable to point to the toolchain folder.
+
+-  Build TF-A:
+
+   .. code:: shell
+
+      export CROSS_COMPILE=<path-to-aarch64-gcc>/bin/aarch64-none-elf-
+
+      make PLAT=morello all

+TC Total Compute Platform
+==========================
+
+Some of the features of TC platform referenced in TF-A include:
+
+- A `System Control Processor <https://github.com/ARM-software/SCP-firmware>`_
+  to abstract power and system management tasks away from application
+  processors. The RAM firmware for SCP is included in the TF-A FIP and is
+  loaded by AP BL2 from FIP in flash to SRAM for copying by SCP (SCP has access
+  to AP SRAM).
+- GICv4
+- Trusted Board Boot
+- SCMI
+- MHUv2
+
+Currently, the main difference between TC0 (TARGET_PLATFORM=0), TC1
+(TARGET_PLATFORM=1), TC2 (TARGET_PLATFORM=2) platforms w.r.t to TF-A
+is the CPUs supported as below:
+
+-  TC0 has support for Cortex A510, Cortex A710 and Cortex X2.
+-  TC1 has support for Cortex A510, Cortex Makalu and Cortex X3.
+-  TC2 has support for Hayes and Hunter Arm CPUs.
+
+
+Boot Sequence
+-------------
+
+The execution begins from SCP_BL1. SCP_BL1 powers up the AP which starts
+executing AP_BL1 and then executes AP_BL2 which loads the SCP_BL2 from
+FIP to SRAM. The SCP has access to AP SRAM. The address and size of SCP_BL2
+is communicated to SCP using SDS. SCP copies SCP_BL2 from SRAM to its own
+RAM and starts executing it. The AP then continues executing the rest of TF-A
+stages including BL31 runtime stage and hands off executing to
+Non-secure world (u-boot).
+
+Build Procedure (TF-A only)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+-  Obtain `Arm toolchain`_ and set the CROSS_COMPILE environment variable to
+   point to the toolchain folder.
+
+-  Build TF-A:
+
+   .. code:: shell
+
+      make PLAT=tc BL33=<path_to_uboot.bin> \
+      SCP_BL2=<path_to_scp_ramfw.bin> TARGET_PLATFORM={0,1,2} all fip
+
+   Enable TBBR by adding the following options to the make command:
+
+   .. code:: shell
+
+      MBEDTLS_DIR=<path_to_mbedtls_directory>  \
+      TRUSTED_BOARD_BOOT=1 \

+NXP i.MX 8 Series
+=================
+
+The i.MX 8 series of applications processors is a feature- and
+performance-scalable multi-core platform that includes single-,
+dual-, and quad-core families based on the Arm® Cortex®
+architecture—including combined Cortex-A72 + Cortex-A53,
+Cortex-A35, and Cortex-M4 based solutions for advanced graphics,
+imaging, machine vision, audio, voice, video, and safety-critical
+applications.
+
+The i.MX8QM is with 2 Cortex-A72 ARM core, 4 Cortex-A53 ARM core
+and 1 Cortex-M4 system controller.
+
+The i.MX8QX is with 4 Cortex-A35 ARM core and 1 Cortex-M4 system
+controller.
+
+The System Controller (SC) represents the evolution of centralized
+control for system-level resources on i.MX8. The heart of the system
+controller is a Cortex-M4 that executes system controller firmware.

+TF-A binary(bl31.bin), u-boot-spl.bin u-boot-nodtb.bin and dtb are combined
+together to generate a binary file called flash.bin, the imx-mkimage tool is
+used to generate flash.bin, and flash.bin needs to be flashed into SD card
+with certain offset for BOOT ROM. the u-boot and imx-mkimage will be upstreamed
+soon, this doc will be updated once they are ready, and the link will be posted.
+
+TBBR Boot Sequence
+------------------
+
+When setting NEED_BL2=1 on imx8mm. We support an alternative way of
+boot sequence to support TBBR.
+
+Bootrom --> SPL --> BL2 --> BL31 --> BL33(u-boot with UEFI) --> grub
+
+This helps us to fulfill the SystemReady EBBR standard.
+BL2 will be in the FIT image and SPL will verify it.
+All of the BL3x will be put in the FIP image. BL2 will verify them.
+In U-boot we turn on the UEFI secure boot features so it can verify
+grub. And we use grub to verify linux kernel.
+
+Measured Boot
+-------------
+
+When setting MEASURED_BOOT=1 on imx8mm we can let TF-A generate event logs
+with a DTB overlay. The overlay will be put at PLAT_IMX8M_DTO_BASE with
+maximum size PLAT_IMX8M_DTO_MAX_SIZE. Then in U-boot we can apply the DTB
+overlay and let U-boot to parse the event log and update the PCRs.
+
+High Assurance Boot (HABv4)
+---------------------------
+
+All actively maintained platforms have a support for High Assurance
+Boot (HABv4), which is implemented via ROM Vector Table (RVT) API to
+extend the Root-of-Trust beyond the SPL. Those calls are done via SMC
+and are executed in EL3, with results returned back to original caller.
+
+Note on DRAM Memory Mapping
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+There is a special case of mapping the DRAM: entire DRAM available on the
+platform is mapped into the EL3 with MT_RW attributes.
+
+Mapping the entire DRAM allows the usage of 2MB block mapping in Level-2
+Translation Table entries, which use less Page Table Entries (PTEs). If
+Level-3 PTE mapping is used instead then additional PTEs would be required,
+which leads to the increase of translation table size.
+
+Due to the fact that the size of SRAM is limited on some platforms in the
+family it should rather be avoided creating additional Level-3 mapping and
+introduce more PTEs, hence the implementation uses Level-2 mapping which
+maps entire DRAM space.
+
+The reason for the MT_RW attribute mapping scheme is the fact that the SMC
+API to get the status and events is called from NS world passing destination
+pointers which are located in DRAM. Mapping DRAM without MT_RW permissions
+causes those locations not to be filled, which in turn causing EL1&0 software
+not to receive replies.
+
+Therefore, DRAM mapping is done with MT_RW attributes, as it is required for
+data exchange between EL3 and EL1&0 software.

+TF-A Build Instructions for Marvell Platforms
+=============================================
+
+This section describes how to compile the Trusted Firmware-A (TF-A) project for Marvell's platforms.
+
+Build Instructions
+------------------
+(1) Set the cross compiler
+
+    .. code:: shell
+
+        > export CROSS_COMPILE=/path/to/toolchain/aarch64-linux-gnu-
+
+(2) Set path for FIP images:
+
+Set U-Boot image path (relatively to TF-A root or absolute path)
+
+    .. code:: shell
+
+        > export BL33=path/to/u-boot.bin
+
+For example: if U-Boot project (and its images) is located at ``~/project/u-boot``,
+BL33 should be ``~/project/u-boot/u-boot.bin``
+
+    .. note::
+
+       *u-boot.bin* should be used and not *u-boot-spl.bin*
+
+Set MSS/SCP image path (mandatory only for A7K/A8K/CN913x when MSS_SUPPORT=1)
+
+    .. code:: shell
+
+        > export SCP_BL2=path/to/mrvl_scp_bl2*.img
+
+(3) Armada-37x0 build requires WTP tools installation.
+
+See below in the section "Tools and external components installation".
+Install ARM 32-bit cross compiler, which is required for building WTMI image for CM3
+
+    .. code:: shell
+
+        > sudo apt-get install gcc-arm-linux-gnueabi
+
+(4) Clean previous build residuals (if any)
+
+    .. code:: shell
+
+        > make distclean
+
+(5) Build TF-A
+
+There are several build options:
+
+- PLAT
+
+        Supported Marvell platforms are:
+
+            - a3700        - A3720 DB, EspressoBin and Turris MOX
+            - a70x0
+            - a70x0_amc    - AMC board
+            - a70x0_mochabin - Globalscale MOCHAbin
+            - a80x0
+            - a80x0_mcbin  - MacchiatoBin
+            - a80x0_puzzle - IEI Puzzle-M801
+            - t9130        - CN913x
+            - t9130_cex7_eval - CN913x CEx7 Evaluation Board
+
+- DEBUG
+
+        Default is without debug information (=0). in order to enable it use ``DEBUG=1``.
+        Can be enabled also when building UART recovery images, there is no issue with it.
+
+        Production TF-A images should be built without this debug option!
+
+- LOG_LEVEL
+
+        Defines the level of logging which will be purged to the default output port.
+
+            -  0 - LOG_LEVEL_NONE
+            - 10 - LOG_LEVEL_ERROR
+            - 20 - LOG_LEVEL_NOTICE (default for DEBUG=0)
+            - 30 - LOG_LEVEL_WARNING
+            - 40 - LOG_LEVEL_INFO (default for DEBUG=1)
+            - 50 - LOG_LEVEL_VERBOSE
+
+- USE_COHERENT_MEM
+
+        This flag determines whether to include the coherent memory region in the
+        BL memory map or not. Enabled by default.
+
+- LLC_ENABLE
+
+        Flag defining the LLC (L3) cache state. The cache is enabled by default (``LLC_ENABLE=1``).
+
+- LLC_SRAM
+
+        Flag enabling the LLC (L3) cache SRAM support. The LLC SRAM is activated and used
+        by Trusted OS (OP-TEE OS, BL32). The TF-A only prepares CCU address translation windows
+        for SRAM address range at BL31 execution stage with window target set to DRAM-0.
+        When Trusted OS activates LLC SRAM, the CCU window target is changed to SRAM.
+        There is no reason to enable this feature if OP-TEE OS built with CFG_WITH_PAGER=n.
+        Only set LLC_SRAM=1 if OP-TEE OS is built with CFG_WITH_PAGER=y.
+
+- MARVELL_SECURE_BOOT
+
+        Build trusted(=1)/non trusted(=0) image, default is non trusted.
+        This parameter is used only for ``mrvl_flash`` and ``mrvl_uart`` targets.
+
+- MV_DDR_PATH
+
+        This parameter is required for ``mrvl_flash`` and ``mrvl_uart`` targets.
+        For A7K/A8K/CN913x it is used for BLE build and for Armada37x0 it used
+        for ddr_tool build.
+
+        Specify path to the full checkout of Marvell mv-ddr-marvell git
+        repository. Checkout must contain also .git subdirectory because
+        mv-ddr build process calls git commands.
+
+        Do not remove any parts of git checkout becuase build process and other
+        applications need them for correct building and version determination.
+
+
+CN913x specific build options:
+
+- CP_NUM
+
+        Total amount of CPs (South Bridge) connected to AP. When the parameter is omitted,
+        the build uses the default number of CPs, which is a number of embedded CPs inside the
+        package: 1 or 2 depending on the SoC used. The parameter is valid for OcteonTX2 CN913x SoC
+        family (PLAT=t9130), which can have external CPs connected to the MCI ports. Valid
+        values with CP_NUM are in a range of 1 to 3.
+
+
+A7K/A8K/CN913x specific build options:
+
+- BLE_PATH
+
+        Points to BLE (Binary ROM extension) sources folder.
+        The parameter is optional, its default value is ``plat/marvell/armada/a8k/common/ble``
+        which uses TF-A in-tree BLE implementation.
+
+- MSS_SUPPORT
+
+        When ``MSS_SUPPORT=1``, then TF-A includes support for Management SubSystem (MSS).
+        When enabled it is required to specify path to the MSS firmware image via ``SCP_BL2``
+        option.
+
+        This option is by default enabled.
+
+- SCP_BL2
+
+        Specify path to the MSS fimware image binary which will run on Cortex-M3 coprocessor.
+        It is available in Marvell binaries-marvell git repository. Required when ``MSS_SUPPORT=1``.
+
+Globalscale MOCHAbin specific build options:
+
+- DDR_TOPOLOGY
+
+        The DDR topology map index/name, default is 0.
+
+        Supported Options:
+            -    0 - DDR4 1CS 2GB
+            -    1 - DDR4 1CS 4GB
+            -    2 - DDR4 2CS 8GB
+
+Armada37x0 specific build options:
+
+- HANDLE_EA_EL3_FIRST_NS
+
+        When ``HANDLE_EA_EL3_FIRST_NS=1``, External Aborts and SError Interrupts, resulting from errors
+        in NS world, will be always trapped in TF-A. TF-A in this case enables dirty hack / workaround for
+        a bug found in U-Boot and Linux kernel PCIe controller driver pci-aardvark.c, traps and then masks
+        SError interrupt caused by AXI SLVERR on external access (syndrome 0xbf000002).
+
+        Otherwise when ``HANDLE_EA_EL3_FIRST_NS=0``, these exceptions will be trapped in the current
+        exception level (or in EL1 if the current exception level is EL0). So exceptions caused by
+        U-Boot will be trapped in U-Boot, exceptions caused by Linux kernel (or user applications)
+        will be trapped in Linux kernel.
+
+        Mentioned bug in pci-aardvark.c driver is fixed in U-Boot version v2021.07 and Linux kernel
+        version v5.13 (workarounded since Linux kernel version 5.9) and also backported in Linux
+        kernel stable releases since versions v5.12.13, v5.10.46, v5.4.128, v4.19.198, v4.14.240.
+
+        If target system has already patched version of U-Boot and Linux kernel then it is strongly
+        recommended to not enable this workaround as it disallows propagating of all External Aborts
+        to running Linux kernel and makes correctable errors as fatal aborts.
+
+        This option is now disabled by default. In past this option has different name "HANDLE_EA_EL3_FIRST" and
+        was enabled by default in TF-A versions v2.2, v2.3, v2.4 and v2.5.
+
+- CM3_SYSTEM_RESET
+
+        When ``CM3_SYSTEM_RESET=1``, the Cortex-M3 secure coprocessor will be used for system reset.
+
+        TF-A will send command 0x0009 with a magic value via the rWTM mailbox interface to the
+        Cortex-M3 secure coprocessor.
+        The firmware running in the coprocessor must either implement this functionality or
+        ignore the 0x0009 command (which is true for the firmware from A3700-utils-marvell
+        repository). If this option is enabled but the firmware does not support this command,
+        an error message will be printed prior trying to reboot via the usual way.
+
+        This option is needed on Turris MOX as a workaround to a HW bug which causes reset to
+        sometime hang the board.
+
+- A3720_DB_PM_WAKEUP_SRC
+
+        For Armada 3720 Development Board only, when ``A3720_DB_PM_WAKEUP_SRC=1``,
+        TF-A will setup PM wake up src configuration. This option is disabled by default.
+
+
+Armada37x0 specific build options for ``mrvl_flash`` and ``mrvl_uart`` targets:
+
+- DDR_TOPOLOGY
+
+        The DDR topology map index/name, default is 0.
+
+        Supported Options:
+            -    0 - DDR3 1CS 512MB (DB-88F3720-DDR3-Modular, EspressoBin V3-V5)
+            -    1 - DDR4 1CS 512MB (DB-88F3720-DDR4-Modular)
+            -    2 - DDR3 2CS   1GB (EspressoBin V3-V5)
+            -    3 - DDR4 2CS   4GB (DB-88F3720-DDR4-Modular)
+            -    4 - DDR3 1CS   1GB (DB-88F3720-DDR3-Modular, EspressoBin V3-V5)
+            -    5 - DDR4 1CS   1GB (EspressoBin V7, EspressoBin-Ultra)
+            -    6 - DDR4 2CS   2GB (EspressoBin V7)
+            -    7 - DDR3 2CS   2GB (EspressoBin V3-V5)
+            - CUST - CUSTOMER BOARD (Customer board settings)
+
+- CLOCKSPRESET
+
+        The clock tree configuration preset including CPU and DDR frequency,
+        default is CPU_800_DDR_800.
+
+            - CPU_600_DDR_600  - CPU at 600 MHz, DDR at 600 MHz
+            - CPU_800_DDR_800  - CPU at 800 MHz, DDR at 800 MHz
+            - CPU_1000_DDR_800 - CPU at 1000 MHz, DDR at 800 MHz
+            - CPU_1200_DDR_750 - CPU at 1200 MHz, DDR at 750 MHz
+
+        Look at Armada37x0 chip package marking on board to identify correct CPU frequency.
+        The last line on package marking (next line after the 88F37x0 line) should contain:
+
+            - C080 or I080 - chip with  800 MHz CPU - use ``CLOCKSPRESET=CPU_800_DDR_800``
+            - C100 or I100 - chip with 1000 MHz CPU - use ``CLOCKSPRESET=CPU_1000_DDR_800``
+            - C120         - chip with 1200 MHz CPU - use ``CLOCKSPRESET=CPU_1200_DDR_750``
+
+- BOOTDEV
+
+        The flash boot device, default is ``SPINOR``.
+
+        Currently, Armada37x0 only supports ``SPINOR``, ``SPINAND``, ``EMMCNORM`` and ``SATA``:
+
+            - SPINOR - SPI NOR flash boot
+            - SPINAND - SPI NAND flash boot
+            - EMMCNORM - eMMC Download Mode
+
+                Download boot loader or program code from eMMC flash into CM3 or CA53
+                Requires full initialization and command sequence
+
+            - SATA - SATA device boot
+
+                Image needs to be stored at disk LBA 0 or at disk partition with
+                MBR type 0x4d (ASCII 'M' as in Marvell) or at disk partition with
+                GPT partition type GUID ``6828311A-BA55-42A4-BCDE-A89BB5EDECAE``.
+
+- PARTNUM
+
+        The boot partition number, default is 0.
+
+        To boot from eMMC, the value should be aligned with the parameter in
+        U-Boot with name of ``CONFIG_SYS_MMC_ENV_PART``, whose value by default is
+        1. For details about CONFIG_SYS_MMC_ENV_PART, please refer to the U-Boot
+        build instructions.
+
+- WTMI_IMG
+
+        The path of the binary can point to an image which
+        does nothing, an image which supports EFUSE or a customized CM3 firmware
+        binary. The default image is ``fuse.bin`` that built from sources in WTP
+        folder, which is the next option. If the default image is OK, then this
+        option should be skipped.
+
+        Please note that this is not a full WTMI image, just a main loop without
+        hardware initialization code. Final WTMI image is built from this WTMI_IMG
+        binary and sys-init code from the WTP directory which sets DDR and CPU
+        clocks according to DDR_TOPOLOGY and CLOCKSPRESET options.
+
+        CZ.NIC as part of Turris project released free and open source WTMI
+        application firmware ``wtmi_app.bin`` for all Armada 3720 devices.
+        This firmware includes additional features like access to Hardware
+        Random Number Generator of Armada 3720 SoC which original Marvell's
+        ``fuse.bin`` image does not have.
+
+        CZ.NIC's Armada 3720 Secure Firmware is available at website:
+
+            https://gitlab.nic.cz/turris/mox-boot-builder/
+
+- WTP
+
+        Specify path to the full checkout of Marvell A3700-utils-marvell git
+        repository. Checkout must contain also .git subdirectory because WTP
+        build process calls git commands.
+
+        WTP build process uses also Marvell mv-ddr-marvell git repository
+        specified in MV_DDR_PATH option.
+
+        Do not remove any parts of git checkout becuase build process and other
+        applications need them for correct building and version determination.
+
+- CRYPTOPP_PATH
+
+        Use this parameter to point to Crypto++ source code
+        directory. If this option is specified then Crypto++ source code in
+        CRYPTOPP_PATH directory will be automatically compiled. Crypto++ library
+        is required for building WTP image tool. Either CRYPTOPP_PATH or
+        CRYPTOPP_LIBDIR with CRYPTOPP_INCDIR needs to be specified for Armada37x0.
+
+- CRYPTOPP_LIBDIR
+
+        Use this parameter to point to the directory with
+        compiled Crypto++ library. By default it points to the CRYPTOPP_PATH.
+
+        On Debian systems it is possible to install system-wide Crypto++ library
+        via command ``apt install libcrypto++-dev`` and specify CRYPTOPP_LIBDIR
+        to ``/usr/lib/``.
+
+- CRYPTOPP_INCDIR
+
+        Use this parameter to point to the directory with
+        header files of Crypto++ library. By default it points to the CRYPTOPP_PATH.
+
+        On Debian systems it is possible to install system-wide Crypto++ library
+        via command ``apt install libcrypto++-dev`` and specify CRYPTOPP_INCDIR
+        to ``/usr/include/crypto++/``.
+
+
+For example, in order to build the image in debug mode with log level up to 'notice' level run
+
+.. code:: shell
+
+    > make DEBUG=1 USE_COHERENT_MEM=0 LOG_LEVEL=20 PLAT=<MARVELL_PLATFORM> mrvl_flash
+
+And if we want to build a Armada37x0 image in debug mode with log level up to 'notice' level,
+the image has the preset CPU at 1000 MHz, preset DDR3 at 800 MHz, the DDR topology of DDR4 2CS,
+the image boot from SPI NOR flash partition 0, and the image is non trusted in WTP, the command
+line is as following
+
+.. code:: shell
+
+    > make DEBUG=1 USE_COHERENT_MEM=0 LOG_LEVEL=20 CLOCKSPRESET=CPU_1000_DDR_800 \
+        MARVELL_SECURE_BOOT=0 DDR_TOPOLOGY=3 BOOTDEV=SPINOR PARTNUM=0 PLAT=a3700 \
+        MV_DDR_PATH=/path/to/mv-ddr-marvell/ WTP=/path/to/A3700-utils-marvell/ \
+        CRYPTOPP_PATH=/path/to/cryptopp/ BL33=/path/to/u-boot.bin \
+        all fip mrvl_bootimage mrvl_flash mrvl_uart
+
+To build just TF-A without WTMI image (useful for A3720 Turris MOX board), run following command:
+
+.. code:: shell
+
+    > make USE_COHERENT_MEM=0 PLAT=a3700 CM3_SYSTEM_RESET=1 BL33=/path/to/u-boot.bin \
+        CROSS_COMPILE=aarch64-linux-gnu- mrvl_bootimage
+
+Here is full example how to build production release of Marvell firmware image (concatenated
+binary of Marvell's A3720 sys-init, CZ.NIC's Armada 3720 Secure Firmware, TF-A and U-Boot) for
+EspressoBin board (PLAT=a3700) with 1GHz CPU (CLOCKSPRESET=CPU_1000_DDR_800) and
+1GB DDR4 RAM (DDR_TOPOLOGY=5):

+
+Produced Marvell firmware flash image: ``trusted-firmware-a/build/a3700/release/flash-image.bin``
+
+Special Build Flags
+--------------------
+
+- PLAT_RECOVERY_IMAGE_ENABLE
+    When set this option to enable secondary recovery function when build atf.
+    In order to build UART recovery image this operation should be disabled for
+    A7K/A8K/CN913x because of hardware limitation (boot from secondary image
+    can interrupt UART recovery process). This MACRO definition is set in
+    ``plat/marvell/armada/a8k/common/include/platform_def.h`` file.
+
+- DDR32
+    In order to work in 32bit DDR, instead of the default 64bit ECC DDR,
+    this flag should be set to 1.
+
+For more information about build options, please refer to the
+:ref:`Build Options` document.
+
+
+Build output
+------------
+Marvell's TF-A compilation generates 8 files:
+
+    - ble.bin		- BLe image (not available for Armada37x0)
+    - bl1.bin		- BL1 image
+    - bl2.bin		- BL2 image
+    - bl31.bin		- BL31 image
+    - fip.bin		- FIP image (contains BL2, BL31 & BL33 (U-Boot) images)
+    - boot-image.bin	- TF-A image (contains BL1 and FIP images)
+    - flash-image.bin	- Flashable Marvell firmware image. For Armada37x0 it
+      contains TIM, WTMI and boot-image.bin images. For other platforms it contains
+      BLe and boot-image.bin images. Should be placed on the boot flash/device.
+    - uart-images.tgz.bin - GZIPed TAR archive which contains Armada37x0 images
+      for booting via UART. Could be loaded via Marvell's WtpDownload tool from
+      A3700-utils-marvell repository.
+
+Additional make target ``mrvl_bootimage`` produce ``boot-image.bin`` file. Target
+``mrvl_flash`` produce final ``flash-image.bin`` file and target ``mrvl_uart``
+produce ``uart-images.tgz.bin`` file.
+
+
+Tools and external components installation
+------------------------------------------
+
+Armada37x0 Builds require installation of additional components
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+(1) ARM cross compiler capable of building images for the service CPU (CM3).

+
+AXI to M-bridge decoding unit driver for Marvell Armada 8K and 8K+ SoCs.
+
+The Runit offers a second level of address windows lookup. It is used to map
+transaction towards the CD BootROM, SPI0, SPI1 and Device bus (NOR).
+
+The Runit contains eight configurable windows. Each window defines a contiguous,
+address space and the properties associated with that address space.

+TF-A Porting Guide for Marvell Platforms
+========================================
+
+This section describes how to port TF-A to a customer board, assuming that the
+SoC being used is already supported in TF-A.
+
+
+Source Code Structure
+---------------------
+
+- The customer platform specific code shall reside under ``plat/marvell/armada/<soc family>/<soc>_cust``
+  (e.g. 'plat/marvell/armada/a8k/a7040_cust').
+- The platform name for build purposes is called ``<soc>_cust`` (e.g. ``a7040_cust``).
+- The build system will reuse all files from within the soc directory, and take only the porting
+  files from the customer platform directory.
+
+Files that require porting are located at ``plat/marvell/armada/<soc family>/<soc>_cust`` directory.
+
+
+Armada-70x0/Armada-80x0 Porting
+-------------------------------
+
+SoC Physical Address Map (marvell_plat_config.c)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This file describes the SoC physical memory mapping to be used for the CCU,
+IOWIN, AXI-MBUS and IOB address decode units (Refer to the functional spec for
+more details).
+
+In most cases, using the default address decode windows should work OK.
+
+In cases where a special physical address map is needed (e.g. Special size for
+PCIe MEM windows, large memory mapped SPI flash...), then porting of the SoC
+memory map is required.
+
+.. note::
+   For a detailed information on how CCU, IOWIN, AXI-MBUS & IOB work, please
+   refer to the SoC functional spec, and under
+   ``docs/plat/marvell/armada/misc/mvebu-[ccu/iob/amb/io-win].rst`` files.
+
+boot loader recovery (marvell_plat_config.c)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+- Background:
+
+  Boot rom can skip the current image and choose to boot from next position if a
+  specific value (``0xDEADB002``) is returned by the ble main function. This
+  feature is used for boot loader recovery by booting from a valid flash-image
+  saved in next position on flash (e.g. address 2M in SPI flash).
+
+  Supported options to implement the skip request are:
+    - GPIO
+    - I2C
+    - User defined
+
+- Porting:
+
+  Under marvell_plat_config.c, implement struct skip_image that includes
+  specific board parameters.
+
+  .. warning::
+     To disable this feature make sure the struct skip_image is not implemented.
+
+- Example:
+
+In A7040-DB specific implementation
+(``plat/marvell/armada/a8k/a70x0/board/marvell_plat_config.c``), the image skip is
+implemented using GPIO: mpp 33 (SW5).
+
+Before resetting the board make sure there is a valid image on the next flash
+address:
+
+ -tftp [valid address] flash-image.bin
+ -sf update [valid address] 0x2000000 [size]
+
+Press reset and keep pressing the button connected to the chosen GPIO pin. A
+skip image request message is printed on the screen and boot rom boots from the
+saved image at the next position.
+
+DDR Porting (dram_port.c)
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This file defines the dram topology and parameters of the target board.
+
+The DDR code is part of the BLE component, which is an extension of ARM Trusted
+Firmware (TF-A).
+
+The DDR driver called mv_ddr is released separately apart from TF-A sources.
+
+The BLE and consequently, the DDR init code is executed at the early stage of
+the boot process.
+
+Each supported platform of the TF-A has its own DDR porting file called
+dram_port.c located at ``atf/plat/marvell/armada/a8k/<platform>/board`` directory.
+
+Please refer to '<path_to_mv_ddr_sources>/doc/porting_guide.txt' for detailed
+porting description.
+
+The build target directory is "build/<platform>/release/ble".
+
+Comphy Porting (phy-porting-layer.h or phy-default-porting-layer.h)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+- Background:
+    Some of the comphy's parameters value depend on the HW connection between
+    the SoC and the PHY. Every board type has specific HW characteristics like
+    wire length. Due to those differences some comphy parameters vary between
+    board types. Therefore each board type can have its own list of values for
+    all relevant comphy parameters. The PHY porting layer specifies which
+    parameters need to be suited and the board designer should provide relevant
+    values.
+
+    The PHY porting layer simplifies updating static values per board type,
+    which are now grouped in one place.
+
+    .. note::
+        The parameters for the same type of comphy may vary even for the same
+        board type, it is because the lanes from comphy-x to some PHY may have
+        different HW characteristic than lanes from comphy-y to the same
+        (multiplexed) or other PHY.
+
+- Porting:
+    The porting layer for PHY was introduced in TF-A. There is one file
+    ``drivers/marvell/comphy/phy-default-porting-layer.h`` which contains the
+    defaults. Those default parameters are used only if there is no appropriate
+    phy-porting-layer.h file under: ``plat/marvell/armada/<soc
+    family>/<platform>/board/phy-porting-layer.h``. If the phy-porting-layer.h
+    exists, the phy-default-porting-layer.h is not going to be included.
+
+    .. warning::
+        Not all comphy types are already reworked to support the PHY porting
+        layer, currently the porting layer is supported for XFI/SFI and SATA
+        comphy types.
+
+    The easiest way to prepare the PHY porting layer for custom board is to copy
+    existing example to a new platform:
+
+    - cp ``plat/marvell/armada/a8k/a80x0/board/phy-porting-layer.h`` "plat/marvell/armada/<soc family>/<platform>/board/phy-porting-layer.h"
+    - adjust relevant parameters or
+    - if different comphy index is used for specific feature, move it to proper table entry and then adjust.
+
+    .. note::
+        The final table size with comphy parameters can be different, depending
+        on the CP module count for given SoC type.
+
+- Example:
+    Example porting layer for armada-8040-db is under:
+    ``plat/marvell/armada/a8k/a80x0/board/phy-porting-layer.h``
+
+    .. note::
+        If there is no PHY porting layer for new platform (missing
+        phy-porting-layer.h), the default values are used
+        (drivers/marvell/comphy/phy-default-porting-layer.h) and the user is
+        warned:
+
+    .. warning::
+        "Using default comphy parameters - it may be required to suit them for
+        your board".

+TF-A UART Booting Instructions for Marvell Platforms
+====================================================
+
+This section describes how to temporary boot the Trusted Firmware-A (TF-A) project over UART
+without flashing it to non-volatile storage for Marvell's platforms.
+
+See :ref:`TF-A Build Instructions for Marvell Platforms` how to build ``mrvl_uart`` and
+``mrvl_flash`` targets used in this section.
+
+Armada37x0 UART image downloading
+---------------------------------
+
+There are two options how to download UART image into any Armada37x0 board.
+
+Marvell Wtpdownloader
+~~~~~~~~~~~~~~~~~~~~~
+
+Marvell Wtpdownloader works only with UART images stored in separate files and supports only upload
+speed with 115200 bauds. Target ``mrvl_uart`` produces GZIPed TAR archive ``uart-images.tgz.bin``
+with either three files ``TIM_ATF.bin``, ``wtmi_h.bin`` and ``boot-image_h.bin`` for non-secure
+boot or with four files ``TIM_ATF_TRUSTED.bin``, ``TIMN_ATF_TRUSTED.bin``, ``wtmi_h.bin`` and
+``boot-image_h.bin`` when secure boot is enabled.
+
+Compilation:
+
+.. code:: shell
+
+    > git clone https://github.com/MarvellEmbeddedProcessors/A3700-utils-marvell.git
+    > make -C A3700-utils-marvell/wtptp/src/Wtpdownloader_Linux -f makefile.mk
+
+It produces executable binary ``A3700-utils-marvell/wtptp/src/Wtpdownloader_Linux/WtpDownload_linux``
+
+To download images from ``uart-images.tgz.bin`` archive unpack it and for non-secure boot variant run:
+
+.. code:: shell
+
+    > stty -F /dev/ttyUSB<port#> clocal
+    > WtpDownload_linux -P UART -C <port#> -E -B TIM_ATF.bin -I wtmi_h.bin -I boot-image_h.bin
+
+After that immediately start terminal on ``/dev/ttyUSB<port#>`` to see boot output.
+
+CZ.NIC mox-imager
+~~~~~~~~~~~~~~~~~
+
+CZ.NIC mox-imager supports all Armada37x0 boards (not only Turris MOX as name suggests). It works
+with either with separate files from ``uart-images.tgz.bin`` archive (like Marvell Wtpdownloader)
+produced by ``mrvl_uart`` target or also with ``flash-image.bin`` file produced by ``mrvl_flash``
+target, which is the exactly same file as used for flashing. So when using CZ.NIC mox-imager there
+is no need to build separate files for UART flashing like in case with Marvell Wtpdownloader.
+
+CZ.NIC mox-imager moreover supports higher upload speeds up to the 6000000 bauds (which seems to
+be limit of Armada37x0 SoC) which is much higher and faster than Marvell Wtpdownloader.
+
+Compilation:
+
+.. code:: shell
+
+    > git clone https://gitlab.nic.cz/turris/mox-imager.git
+    > make -C mox-imager
+
+It produces executable binary ``mox-imager/mox-imager``
+
+To download single file image built by ``mrvl_flash`` target at the highest speed, run:
+
+.. code:: shell
+
+    > mox-imager -D /dev/ttyUSB<port#> -E -b 6000000 -t flash-image.bin
+
+To download images from ``uart-images.tgz.bin`` archive built by ``mrvl_uart`` target for
+non-secure boot variant (like Wtpdownloader) but at the highest speed, first unpack
+``uart-images.tgz.bin`` archive and then run:
+
+.. code:: shell
+
+    > mox-imager -D /dev/ttyUSB<port#> -E -b 6000000 -t TIM_ATF.bin wtmi_h.bin boot-image_h.bin
+
+CZ.NIC mox-imager after successful download will start its own mini terminal (option ``-t``) to
+not loose any boot output. It also prints boot output which is sent either by image files or by
+bootrom during transferring of image files. This mini terminal can be quit by CTRL-\\ + C keypress.
+
+
+A7K/A8K/CN913x UART image downloading
+-------------------------------------
+
+A7K/A8K/CN913x uses same image ``flash-image.bin`` for both flashing and booting over UART.
+For downloading image over UART it is possible to use mvebu64boot tool.
+
+Compilation:
+
+.. code:: shell
+
+    > git clone https://github.com/pali/mvebu64boot.git
+    > make -C mvebu64boot
+
+It produces executable binary ``mvebu64boot/mvebu64boot``
+
+To download ``flash-image.bin`` image run:
+
+.. code:: shell
+
+    > mvebu64boot -t -b flash-image.bin /dev/ttyUSB0
+
+After successful download it will start own mini terminal (option ``-t``) like CZ.NIC mox-imager.

+NVIDIA Tegra
+============

+-  .. rubric:: T194
+      :name: t194
+
+T194 has eight NVIDIA Carmel CPU cores in a coherent multi-processor
+configuration. The Carmel cores support the ARM Architecture version 8.2,
+executing both 64-bit AArch64 code, and 32-bit AArch32 code. The Carmel
+processors are organized as four dual-core clusters, where each cluster has
+a dedicated 2 MiB Level-2 unified cache. A high speed coherency fabric connects
+these processor complexes and allows heterogeneous multi-processing with all
+eight cores if required.
+
+-  .. rubric:: T186
+      :name: t186
+
+The NVIDIA® Parker (T186) series system-on-chip (SoC) delivers a heterogeneous
+multi-processing (HMP) solution designed to optimize performance and
+efficiency.
+
+T186 has Dual NVIDIA Denver2 ARM® CPU cores, plus Quad ARM Cortex®-A57 cores,
+in a coherent multiprocessor configuration. The Denver 2 and Cortex-A57 cores
+support ARMv8, executing both 64-bit Aarch64 code, and 32-bit Aarch32 code
+including legacy ARMv7 applications. The Denver 2 processors each have 128 KB
+Instruction and 64 KB Data Level 1 caches; and have a 2MB shared Level 2
+unified cache. The Cortex-A57 processors each have 48 KB Instruction and 32 KB
+Data Level 1 caches; and also have a 2 MB shared Level 2 unified cache. A
+high speed coherency fabric connects these two processor complexes and allows
+heterogeneous multi-processing with all six cores if required.
+
+Denver is NVIDIA's own custom-designed, 64-bit, dual-core CPU which is
+fully Armv8-A architecture compatible. Each of the two Denver cores
+implements a 7-way superscalar microarchitecture (up to 7 concurrent
+micro-ops can be executed per clock), and includes a 128KB 4-way L1
+instruction cache, a 64KB 4-way L1 data cache, and a 2MB 16-way L2
+cache, which services both cores.
+
+Denver implements an innovative process called Dynamic Code Optimization,
+which optimizes frequently used software routines at runtime into dense,
+highly tuned microcode-equivalent routines. These are stored in a
+dedicated, 128MB main-memory-based optimization cache. After being read
+into the instruction cache, the optimized micro-ops are executed,
+re-fetched and executed from the instruction cache as long as needed and
+capacity allows.
+
+Effectively, this reduces the need to re-optimize the software routines.
+Instead of using hardware to extract the instruction-level parallelism
+(ILP) inherent in the code, Denver extracts the ILP once via software
+techniques, and then executes those routines repeatedly, thus amortizing
+the cost of ILP extraction over the many execution instances.
+
+Denver also features new low latency power-state transitions, in addition
+to extensive power-gating and dynamic voltage and clock scaling based on
+workloads.
+
+-  .. rubric:: T210
+      :name: t210
+
+T210 has Quad Arm® Cortex®-A57 cores in a switched configuration with a
+companion set of quad Arm Cortex-A53 cores. The Cortex-A57 and A53 cores
+support Armv8-A, executing both 64-bit Aarch64 code, and 32-bit Aarch32 code
+including legacy Armv7-A applications. The Cortex-A57 processors each have
+48 KB Instruction and 32 KB Data Level 1 caches; and have a 2 MB shared
+Level 2 unified cache. The Cortex-A53 processors each have 32 KB Instruction
+and 32 KB Data Level 1 caches; and have a 512 KB shared Level 2 unified cache.

+Directory structure
+-------------------
+
+-  plat/nvidia/tegra/common - Common code for all Tegra SoCs
+-  plat/nvidia/tegra/soc/txxx - Chip specific code
+
+Trusted OS dispatcher
+---------------------
+
+Tegra supports multiple Trusted OS'.
+
+- Trusted Little Kernel (TLK): In order to include the 'tlkd' dispatcher in
+  the image, pass 'SPD=tlkd' on the command line while preparing a bl31 image.
+- Trusty: In order to include the 'trusty' dispatcher in the image, pass
+  'SPD=trusty' on the command line while preparing a bl31 image.
+
+This allows other Trusted OS vendors to use the upstream code and include
+their dispatchers in the image without changing any makefiles.
+
+These are the supported Trusted OS' by Tegra platforms.
+
+- Tegra210: TLK and Trusty
+- Tegra186: Trusty
+- Tegra194: Trusty
+
+Scatter files
+-------------
+
+Tegra platforms currently support scatter files and ld.S scripts. The scatter
+files help support ARMLINK linker to generate BL31 binaries. For now, there
+exists a common scatter file, plat/nvidia/tegra/scat/bl31.scat, for all Tegra
+SoCs. The `LINKER` build variable needs to point to the ARMLINK binary for
+the scatter file to be used. Tegra platforms have verified BL31 image generation
+with ARMCLANG (compilation) and ARMLINK (linking) for the Tegra186 platforms.
+
+Preparing the BL31 image to run on Tegra SoCs
+---------------------------------------------
+
+.. code:: shell
+
+    CROSS_COMPILE=<path-to-aarch64-gcc>/bin/aarch64-none-elf- make PLAT=tegra \
+    TARGET_SOC=<target-soc e.g. t194|t186|t210> SPD=<dispatcher e.g. trusty|tlkd>
+    bl31
+
+Platforms wanting to use different TZDRAM\_BASE, can add ``TZDRAM_BASE=<value>``
+to the build command line.
+
+The Tegra platform code expects a pointer to the following platform specific
+structure via 'x1' register from the BL2 layer which is used by the
+bl31\_early\_platform\_setup() handler to extract the TZDRAM carveout base and
+size for loading the Trusted OS and the UART port ID to be used. The Tegra
+memory controller driver programs this base/size in order to restrict NS
+accesses.
+
+typedef struct plat\_params\_from\_bl2 {
+/\* TZ memory size */
+uint64\_t tzdram\_size;
+/* TZ memory base */
+uint64\_t tzdram\_base;
+/* UART port ID \*/
+int uart\_id;
+/* L2 ECC parity protection disable flag \*/
+int l2\_ecc\_parity\_prot\_dis;
+/* SHMEM base address for storing the boot logs \*/
+uint64\_t boot\_profiler\_shmem\_base;
+} plat\_params\_from\_bl2\_t;
+
+Power Management
+----------------
+
+The PSCI implementation expects each platform to expose the 'power state'
+parameter to be used during the 'SYSTEM SUSPEND' call. The state-id field
+is implementation defined on Tegra SoCs and is preferably defined by
+tegra\_def.h.
+
+Tegra configs
+-------------
+
+-  'tegra\_enable\_l2\_ecc\_parity\_prot': This flag enables the L2 ECC and Parity
+   Protection bit, for Arm Cortex-A57 CPUs, during CPU boot. This flag will
+   be enabled by Tegrs SoCs during 'Cluster power up' or 'System Suspend' exit.

+DDR Memory Layout
+--------------------------
+
+NXP Platforms divide DRAM into banks:
+
+- DRAM0 Bank:  Maximum size of this bank is fixed to 2GB, DRAM0 size is defined in platform_def.h if it is less than 2GB.
+
+- DRAM1 ~ DRAMn Bank:  Greater than 2GB belongs to DRAM1 and following banks, and size of DRAMn Bank varies for one platform to others.
+
+The following diagram is default DRAM0 memory layout in which secure memory is at top of DRAM0.

+
+Build Procedure
+---------------
+
+-  Fetch all the above repositories into local host.
+
+-  Prepare AARCH64 toolchain and set the environment variable "CROSS_COMPILE".
+
+   .. code:: shell
+
+       export CROSS_COMPILE=.../bin/aarch64-linux-gnu-
+
+-  Build RCW. Refer README from the respective cloned folder for more details.
+
+-  Build u-boot and OPTee firstly, and get binary images: u-boot.bin and tee.bin.
+   For u-boot you can use the <platform>_tfa_defconfig for build.
+
+-  Copy/clone the repo "ddr-phy-binary" to the tfa directory for platform needing ddr-fip.
+
+-  Below are the steps to build TF-A images for the supported platforms.

+
+Second method to do the fuse provsioning:
+=========================================
+
+This method is used for quick way to provision fuses.
+Typically used by those who needs to provision number of boards.
+
+- Enable POVDD:
+  -- Refer the table above to enable POVDD.
+
+     Note: If GPIO Pin supports enabling POVDD, it can be done through the below input_fuse_file.
+
+  -- Once the POVDD is enabled, make sure to set variable POVDD_ENABLE := yes, in the platform.mk.
+
+- User need to populate the "input_fuse_file", corresponding to the platform for:
+
+  -- OTPMK
+  -- SRKH
+
+  Table of fuse provisioning input file for every supported platform:
+
++---+----------------------------------+-----------------------------------------------------------------+

+NXP Platforms:
+--------------
+TRUSTED_BOARD_BOOT option can be enabled by specifying TRUSTED_BOARD_BOOT=1 on command line during make.
+
+
+
+Bare-Minimum Preparation to run  TBBR on NXP Platforms:
+=======================================================
+- OTPMK(One Time Programable Key) needs to be burnt in fuses.
+  -- It is the 256 bit key that stores a secret value used by the NXP SEC 4.0 IP in Trusted or Secure mode.
+
+     Note: It is primarily for the purpose of decrypting additional secrets stored in system non-volatile memory.
+
+  -- NXP CST tool gives an option to generate it.
+
+   Use the below command from directory 'cst', with correct options.
+
+   .. code:: shell
+
+     ./gen_otpmk_drbg
+
+- SRKH (Super Root Key Hash) needs to be burnt in fuses.
+  -- It is the 256 bit hash of the list of the public keys of the SRK key pair.
+  -- NXP CST tool gives an option to generate the RSA key pair and its hash.
+
+   Use the below command from directory 'cst', with correct options.
+
+   .. code:: shell
+
+     ./gen_keys
+
+Refer fuse frovisioning readme 'nxp-ls-fuse-prov.rst' for steps to blow these keys.
+
+
+
+Two options are provided for TRUSTED_BOARD_BOOT:
+================================================
+
+-------------------------------------------------------------------------
+Option 1: CoT using X 509 certificates
+-------------------------------------------------------------------------
+
+- This CoT is as provided by ARM.
+
+- To use this option user needs to specify mbedtld dir path in MBEDTLS_DIR.
+
+- To generate CSF header, path of CST repository needs to be specified as CST_DIR
+
+- CSF header is embedded to each of the BL2 image.
+
+- GENERATE_COT=1 adds the tool 'cert_create' to the build environment to generate:
+  -- X509 Certificates as (.crt) files.
+  -- X509 Pem key file as (.pem) files.
+
+- SAVE_KEYS=1 saves the keys and certificates, if GENERATE_COT=1.
+  -- For this to work, file name for cert and keys are provided as part of  compilation or build command.
+
+     --- default file names will be used, incase not provided as part compilation or build command.
+     --- default folder 'BUILD_PLAT' will be used to store them.
+
+- ROTPK for x.509 certificates is generated and embedded in bl2.bin and
+  verified as part of CoT by Boot ROM during secure boot.
+
+- Compilation steps:
+
+All Images
+   .. code:: shell
+
+       make PLAT=$PLAT TRUSTED_BOARD_BOOT=1 GENERATE_COT=1 MBEDTLS_DIR=$MBEDTLS_PATH CST_DIR=$CST_DIR_PATH \
+       BOOT_MODE=<platform_supported_boot_mode> \
+       RCW=$RCW_BIN \
+       BL32=$TEE_BIN SPD=opteed\
+       BL33=$UBOOT_SECURE_BIN \
+       pbl \
+       fip
+
+Additional FIP_DDR Image (For NXP platforms like lx2160a)
+   .. code:: shell
+
+       make PLAT=$PLAT TRUSTED_BOARD_BOOT=1 GENERATE_COT=1 MBEDTLS_DIR=$MBEDTLS_PATH fip_ddr
+
+      Note: make target 'fip_ddr' should never be combine with other make target 'fip', 'pbl' & 'bl2'.
+
+-------------------------------------------------------------------------
+Option 2: CoT using NXP CSF headers.
+-------------------------------------------------------------------------
+
+- This option is automatically selected when TRUSTED_BOARD_BOOT is set but MBEDTLS_DIR path is not specified.
+
+- CSF header is embedded to each of the BL31, BL32 and  BL33 image.
+
+- To generate CSF header, path of CST repository needs to be specified as CST_DIR
+
+- Default input files for CSF header generation is added in this repo.
+
+- Default input file requires user to generate RSA key pair named
+  -- srk.pri, and
+  -- srk.pub, and add them in ATF repo.
+  -- These keys can be generated using gen_keys tool of CST.
+
+- To change the input file , user can use the options BL33_INPUT_FILE, BL32_INPUT_FILE, BL31_INPUT_FILE
+
+- There are 2 paths in secure boot flow :
+  -- Development Mode (sb_en in RCW = 1, SFP->OSPR, ITS = 0)
+
+     --- In this flow , even on ROTPK comparison failure, flow would continue.
+     --- However SNVS is transitioned to non-secure state
+
+  -- Production mode (SFP->OSPR, ITS = 1)
+
+     --- Any failure is fatal failure
+
+- Compilation steps:
+
+All Images
+   .. code:: shell
+
+       make PLAT=$PLAT TRUSTED_BOARD_BOOT=1 CST_DIR=$CST_DIR_PATH \
+       BOOT_MODE=<platform_supported_boot_mode> \
+       RCW=$RCW_BIN \
+       BL32=$TEE_BIN SPD=opteed\
+       BL33=$UBOOT_SECURE_BIN \
+       pbl \
+       fip
+
+Additional FIP_DDR Image (For NXP platforms like lx2160a)
+   .. code:: shell
+
+       make PLAT=$PLAT TRUSTED_BOARD_BOOT=1 CST_DIR=$CST_DIR_PATH fip_ddr
+
+- Compilation Steps with build option for generic image processing filters to prepend CSF header:
+  --  Generic image processing filters to prepend CSF header
+
+      BL32_INPUT_FILE = < file name>
+      BL33_INPUT_FILE = <file name>
+
+   .. code:: shell

+
+Build Procedure
+~~~~~~~~~~~~~~~
+
+-  Fetch all the above 3 repositories into local host.
+   Make all the repositories in the same ${BUILD\_PATH}.
+
+-  Prepare the AARCH64 toolchain.
+
+-  Build u-boot using poplar_defconfig
+
+.. code:: bash
+
+       make CROSS_COMPILE=aarch64-linux-gnu- poplar_defconfig
+       make CROSS_COMPILE=aarch64-linux-gnu-
+
+-  Build atf providing the previously generated u-boot.bin as the BL33 image
+
+.. code:: bash
+
+       make CROSS_COMPILE=aarch64-linux-gnu-  all fip SPD=none PLAT=poplar
+       BL33=u-boot.bin
+
+-  Build l-loader (generated the final fastboot.bin)
+       1. copy the atf generated files fip.bin and bl1.bin to l-loader/atf/
+       2. export ARM_TRUSTED_FIRMWARE=${ATF_SOURCE_PATH)
+       3. make
+
+Install Procedure
+-----------------
+

+Trusted Firmware-A (TF-A) implements the EL3 firmware layer for QEMU SBSA
+Armv8-A. While running Qemu from command line, we need to supply two Flash
+images. First Secure BootRom is supplied by -pflash argument. This Flash image
+is made by EDK2 build system by composing BL1 and FIP. Second parameter for Qemu
+is responsible for Non-secure rom which also given with -pflash argument and
+contains of UEFI and EFI variables (also made by EDK2 build system). Semihosting
+is not used
+
+When QEMU starts all CPUs are released simultaneously, BL1 selects a
+primary CPU to handle the boot and the secondaries are placed in a polling
+loop to be released by normal world via PSCI.
+
+BL2 edits the FDT, generated by QEMU at run-time to add a node describing PSCI
+and also enable methods for the CPUs.
+
+Current limitations:
+
+-  Only cold boot is supported
+
+To build TF-A:
+
+::
+
+    git clone https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git tfa
+    cd tfa
+    export CROSS_COMPILE=aarch64-none-elf-
+    make PLAT=qemu_sbsa all fip
+
+To build TF-A with BL32 and SPM enabled(StandaloneMM as a Secure Payload):
+
+::
+
+    git clone https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git tfa
+    cd tfa
+    export CROSS_COMPILE=aarch64-none-elf-
+    make PLAT=qemu_sbsa BL32=../STANDALONE_MM.fd SPM_MM=1 EL3_EXCEPTION_HANDLING=1 all fip
+
+Images will be placed at build/qemu_sbsa/release (bl1.bin and fip.bin).
+Need to copy them into top directory for EDK2 compilation.
+
+::
+
+    cp build/qemu_sbsa/release/bl1.bin ../
+    cp build/qemu_sbsa/release/fip.bin ../
+
+Those images cannot be used by itself (no semihosing support). Flash images are built by
+EDK2 build system, refer to edk2-platform repo for full build instructions.

+QEMU virt Armv8-A
+=================
+
+Trusted Firmware-A (TF-A) implements the EL3 firmware layer for QEMU virt
+Armv8-A. BL1 is used as the BootROM, supplied with the -bios argument.
+When QEMU starts all CPUs are released simultaneously, BL1 selects a
+primary CPU to handle the boot and the secondaries are placed in a polling
+loop to be released by normal world via PSCI.
+
+BL2 edits the Flattened Device Tree, FDT, generated by QEMU at run-time to
+add a node describing PSCI and also enable methods for the CPUs.
+
+If ``ARM_LINUX_KERNEL_AS_BL33`` is set to 1 then this FDT will be passed to BL33
+via register x0, as expected by a Linux kernel. This allows a Linux kernel image
+to be booted directly as BL33 rather than using a bootloader.
+
+An ARM64 defconfig v5.5 Linux kernel is known to boot, FDT doesn't need to be
+provided as it's generated by QEMU.
+
+Current limitations:
+
+-  Only cold boot is supported
+
+Getting non-TF images
+---------------------
+
+``QEMU_EFI.fd`` can be downloaded from
+http://snapshots.linaro.org/components/kernel/leg-virt-tianocore-edk2-upstream/latest/QEMU-KERNEL-AARCH64/RELEASE_GCC5/QEMU_EFI.fd
+
+or, can be built as follows:
+
+.. code:: shell
+
+    git clone https://github.com/tianocore/edk2.git
+    cd edk2
+    git submodule update --init
+    make -C BaseTools
+    source edksetup.sh
+    export GCC5_AARCH64_PREFIX=aarch64-linux-gnu-
+    build -a AARCH64 -t GCC5 -p ArmVirtPkg/ArmVirtQemuKernel.dsc
+
+````
+
+Then, you will get ``Build/ArmVirtQemuKernel-AARCH64/DEBUG_GCC5/FV/QEMU_EFI.fd``
+
+Please note you do not need to use GCC 5 in spite of the environment variable
+``GCC5_AARCH64_PREFIX``
+
+The rootfs can be built by using Buildroot as follows:
+
+.. code:: shell
+
+    git clone git://git.buildroot.net/buildroot.git
+    cd buildroot
+    make qemu_aarch64_virt_defconfig
+    utils/config -e BR2_TARGET_ROOTFS_CPIO
+    utils/config -e BR2_TARGET_ROOTFS_CPIO_GZIP
+    make olddefconfig
+    make
+
+Then, you will get ``output/images/rootfs.cpio.gz``.
+
+Booting via semi-hosting option
+-------------------------------
+
+Boot binaries, except BL1, are primarily loaded via semi-hosting so all
+binaries has to reside in the same directory as QEMU is started from. This
+is conveniently achieved with symlinks the local names as:
+
+-  ``bl2.bin`` -> BL2
+-  ``bl31.bin`` -> BL31
+-  ``bl33.bin`` -> BL33 (``QEMU_EFI.fd``)
+-  ``Image`` -> linux/arch/arm64/boot/Image
+
+To build:
+
+.. code:: shell
+
+    make CROSS_COMPILE=aarch64-none-elf- PLAT=qemu
+
+To start (QEMU v5.0.0):
+
+.. code:: shell
+
+    qemu-system-aarch64 -nographic -machine virt,secure=on -cpu cortex-a57  \
+        -kernel Image                           \
+        -append "console=ttyAMA0,38400 keep_bootcon"   \
+        -initrd rootfs.cpio.gz -smp 2 -m 1024 -bios bl1.bin   \
+        -d unimp -semihosting-config enable,target=native
+
+Booting via flash based firmwares
+---------------------------------
+
+Boot firmwares are loaded via secure FLASH0 device so ``bl1.bin`` and
+``fip.bin`` should be concatenated to create a ``flash.bin`` that is flashed
+onto secure FLASH0.
+
+-  ``bl32.bin`` -> BL32 (``tee-header_v2.bin``)
+-  ``bl32_extra1.bin`` -> BL32 Extra1 (``tee-pager_v2.bin``)
+-  ``bl32_extra2.bin`` -> BL32 Extra2 (``tee-pageable_v2.bin``)
+-  ``bl33.bin`` -> BL33 (``QEMU_EFI.fd``)
+-  ``Image`` -> linux/arch/arm64/boot/Image
+
+To build:
+
+.. code:: shell
+
+    make CROSS_COMPILE=aarch64-linux-gnu- PLAT=qemu BL32=bl32.bin \
+        BL32_EXTRA1=bl32_extra1.bin BL32_EXTRA2=bl32_extra2.bin \
+        BL33=bl33.bin BL32_RAM_LOCATION=tdram SPD=opteed all fip
+
+To build with TBBR enabled, BL31 and BL32 encrypted with test key:
+
+.. code:: shell
+
+    make CROSS_COMPILE=aarch64-linux-gnu- PLAT=qemu BL32=bl32.bin \
+        BL32_EXTRA1=bl32_extra1.bin BL32_EXTRA2=bl32_extra2.bin \
+        BL33=bl33.bin BL32_RAM_LOCATION=tdram SPD=opteed all fip \

+        GENERATE_COT=1 DECRYPTION_SUPPORT=aes_gcm FW_ENC_STATUS=0 \
+        ENCRYPT_BL31=1 ENCRYPT_BL32=1
+
+To build flash.bin:
+
+.. code:: shell
+
+    dd if=build/qemu/release/bl1.bin of=flash.bin bs=4096 conv=notrunc
+    dd if=build/qemu/release/fip.bin of=flash.bin seek=64 bs=4096 conv=notrunc
+
+To start (QEMU v5.0.0):
+
+.. code:: shell
+
+    qemu-system-aarch64 -nographic -machine virt,secure=on -cpu cortex-a57  \
+        -kernel Image -no-acpi                     \
+        -append 'console=ttyAMA0,38400 keep_bootcon'  \
+        -initrd rootfs.cpio.gz -smp 2 -m 1024 -bios flash.bin   \
+        -d unimp
+
+Running QEMU in OpenCI
+-----------------------
+
+Linaro's continuous integration platform OpenCI supports running emulated tests
+on QEMU. The tests are kicked off on Jenkins and deployed through the Linaro
+Automation and Validation Architecture `LAVA`_.
+
+There are a set of Linux boot tests provided in OpenCI. They rely on prebuilt
+`binaries`_ for UEFI, the kernel, root file system, as well as, any other TF-A
+dependencies, and are run as part of the OpenCI TF-A `daily job`_. To run them
+manually, a `builder`_ job may be triggered with the test configuration
+``qemu-boot-tests``.
+
+
+You may see the following warning repeated several times in the boot logs:
+
+.. code:: shell
+
+    pflash_write: Write to buffer emulation is flawed
+
+Please ignore this as it is an unresolved `issue in QEMU`_, it is an internal
+QEMU warning that logs flawed use of "write to buffer".
+
+.. note::
+    For more information on how to trigger jobs in OpenCI, please refer to
+    Linaro's CI documentation, which explains how to trigger a `manual job`_.

+Qualcomm Snapdragon 410 (MSM8916/APQ8016)
+=========================================
+
+The `Qualcomm Snapdragon 410`_ is Qualcomm's first 64-bit SoC, released in 2014
+with four ARM Cortex-A53 cores. There are differents variants (MSM8916,
+APQ8016(E), ...) that are all very similar. A popular device based on APQ8016E
+is the `DragonBoard 410c`_ single-board computer, but the SoC is also used in
+various mid-range smartphones/tablets.
+
+The TF-A/BL31 port for MSM8916 provides a minimal, community-maintained
+EL3 firmware. It is primarily based on information from the public
+`Snapdragon 410E Technical Reference Manual`_ combined with a lot of
+trial and error to actually make it work.
+
+.. note::
+	Unlike the :doc:`QTI SC7180/SC7280 <qti>` ports, this port does **not**
+	make use of a proprietary binary components (QTISECLIB). It is fully
+	open-source but therefore limited to publicly documented hardware
+	components.
+
+Functionality
+-------------
+
+The BL31 port is much more minimal compared to the original firmware and
+therefore expects the non-secure world (e.g. Linux) to manage more hardware,
+such as the SMMUs and all remote processors (RPM, WCNSS, Venus, Modem).
+Everything except modem is currently functional with a slightly modified version
+of mainline Linux.
+
+.. warning::
+	This port is **not secure**. There is no special secure memory and the
+	used DRAM is available from both the non-secure and secure worlds.
+	Unfortunately, the hardware used for memory protection is not described
+	in the APQ8016E documentation.
+
+The port is primarily intended as a minimal PSCI implementation (without a
+separate secure world) where this limitation is not a big problem. Booting
+secondary CPU cores (PSCI ``CPU_ON``) is supported. Basic CPU core power
+management (``CPU_SUSPEND``) is functional but still work-in-progress and
+will be added later once ready.
+
+Boot Flow
+---------
+BL31 replaces the original ``tz`` firmware in the boot flow::
+
+	Boot ROM (PBL) -> SBL -> BL31 (EL3) -> U-Boot (EL2) -> Linux (EL2)
+
+By default, BL31 enters the non-secure world in EL2 AArch64 state at address
+``0x8f600000``. The original hypervisor firmware (``hyp``) is not used, you can
+use KVM or another hypervisor. The entry address is fixed in the BL31 binary
+but can be changed using the ``PRELOADED_BL33_BASE`` make file parameter.
+
+Using an AArch64 bootloader (such as `U-Boot for DragonBoard 410c`_) is
+recommended. AArch32 bootloaders (such as the original Little Kernel bootloader
+from Qualcomm) are not directly supported, although it is possible to use an EL2
+shim loader to temporarily switch to AArch32 state.
+
+Installation
+------------
+First, setup the cross compiler for AArch64 and build TF-A for ``msm8916``::
+
+	$ make CROSS_COMPILE=aarch64-linux-gnu- PLAT=msm8916
+
+The BL31 ELF image is generated in ``build/msm8916/release/bl31/bl31.elf``.
+This image must be "signed" before flashing it, even if the board has secure
+boot disabled. In this case the signature does not provide any security,
+but it provides the firmware with required metadata.
+
+The `DragonBoard 410c`_ does not have secure boot enabled by default. In this
+case you can simply sign the ELF image using a randomly generated key. You can
+use e.g. `qtestsign`_::
+
+	$ ./qtestsign.py tz build/msm8916/release/bl31/bl31.elf
+
+Then install the resulting ``build/msm8916/release/bl31/bl31-test-signed.mbn``
+to the ``tz`` partition on the device. BL31 should be running after a reboot.
+
+.. warning::
+	Do not flash incorrectly signed firmware on devices that have secure
+	boot enabled! Make sure that you have a way to recover the board in case
+	of problems (e.g. using EDL).
+
+Boot Trace

+this (with ``DEBUG=1``, otherwise only the ``NOTICE`` lines are shown)::

+Build Procedure
+~~~~~~~~~~~~~~~
+
+QTI SoC expects TF-A's BL31 to get integrated with other boot software
+Coreboot, so only bl31.elf need to get build from the TF-A repository.
+
+The build command looks like
+
+    make CROSS_COMPILE=aarch64-linux-gnu- PLAT=sc7180 COREBOOT=1
+
+update value of CROSS_COMPILE argument with your cross-compilation toolchain.
+
+Additional QTISECLIB_PATH=<path to qtiseclib> can be added in build command.
+if QTISECLIB_PATH is not added in build command stub implementation of qtiseclib
+is picked. qtiseclib with stub implementation doesn't boot device. This was
+added to satisfy compilation.

+Overview
+--------
+On the rcar-gen3 the BOOTROM starts the cpu at EL3; for this port BL2
+will therefore be entered at this exception level (the Renesas' ATF
+reference tree [1] resets into EL1 before entering BL2 - see its
+bl2.ld.S)
+
+BL2 initializes DDR (and on some platforms i2c to interface to the
+PMIC) before determining the boot reason (cold or warm).
+
+During suspend all CPUs are switched off and the DDR is put in backup
+mode (some kind of self-refresh mode). This means that BL2 is always
+entered in a cold boot scenario.
+
+Once BL2 boots, it determines the boot reason, writes it to shared
+memory (BOOT_KIND_BASE) together with the BL31 parameters
+(PARAMS_BASE) and jumps to BL31.
+
+To all effects, BL31 is as if it is being entered in reset mode since
+it still needs to initialize the rest of the cores; this is the reason
+behind using direct shared memory access to  BOOT_KIND_BASE _and_
+PARAMS_BASE instead of using registers to get to those locations (see
+el3_common_macros.S and bl31_entrypoint.S for the RESET_TO_BL31 use
+case).
+
+Depending on the boot reason BL31 initializes the rest of the cores:
+in case of suspend, it uses a MBOX memory region to recover the
+program counters.

+Rockchip SoCs
+=============
+
+Trusted Firmware-A supports a number of Rockchip ARM SoCs from both
+AARCH32 and AARCH64 fields.
+
+This includes right now:
+-  px30: Quad-Core Cortex-A53
+-  rk3288: Quad-Core Cortex-A17 (past A12)
+-  rk3328: Quad-Core Cortex-A53
+-  rk3368: Octa-Core Cortex-A53
+-  rk3399: Hexa-Core Cortex-A53/A72
+
+
+Boot Sequence
+-------------
+
+For AARCH32:
+    Bootrom --> BL1/BL2 --> BL32 --> BL33 --> Linux kernel
+
+For AARCH64:
+    Bootrom --> BL1/BL2 --> BL31 --> BL33 --> Linux kernel
+
+BL1/2 and BL33 can currently be supplied from either:
+-  Coreboot + Depthcharge
+-  U-Boot - either separately as TPL+SPL or only SPL
+
+
+How to build
+------------
+
+Rockchip SoCs expect TF-A's BL31 (AARCH64) or BL32 (AARCH32) to get
+integrated with other boot software like U-Boot or Coreboot, so only
+these images need to get build from the TF-A repository.
+
+For AARCH64 architectures the build command looks like
+
+    make CROSS_COMPILE=aarch64-linux-gnu- PLAT=rk3399 bl32
+
+while AARCH32 needs a slightly different command
+
+    make ARCH=aarch32 CROSS_COMPILE=arm-linux-gnueabihf- PLAT=rk3288 AARCH32_SP=sp_min bl32
+
+Both need replacing the PLAT argument with the platform from above you
+want to build for and the CROSS_COMPILE argument with you cross-
+compilation toolchain.
+
+
+How to deploy
+-------------
+
+Both upstream U-Boot and Coreboot projects contain instructions on where
+to put the built images during their respective build process.
+So after successfully building TF-A just follow their build instructions
+to continue.

+Raspberry Pi 3
+==============
+
+The `Raspberry Pi 3`_ is an inexpensive single-board computer that contains four
+Arm Cortex-A53 cores.
+
+The following instructions explain how to use this port of the TF-A with the
+default distribution of `Raspbian`_ because that's the distribution officially
+supported by the Raspberry Pi Foundation. At the moment of writing this, the
+officially supported kernel is a AArch32 kernel. This doesn't mean that this
+port of TF-A can't boot a AArch64 kernel. The `Linux tree fork`_ maintained by
+the Foundation can be compiled for AArch64 by following the steps in
+`AArch64 kernel build instructions`_.
+
+**IMPORTANT NOTE**: This port isn't secure. All of the memory used is DRAM,
+which is available from both the Non-secure and Secure worlds. This port
+shouldn't be considered more than a prototype to play with and implement
+elements like PSCI to support the Linux kernel.
+
+Design
+------
+
+The SoC used by the Raspberry Pi 3 is the Broadcom BCM2837. It is a SoC with a
+VideoCore IV that acts as primary processor (and loads everything from the SD
+card) and is located between all Arm cores and the DRAM. Check the `Raspberry Pi
+3 documentation`_ for more information.
+
+This explains why it is possible to change the execution state (AArch64/AArch32)
+depending on a few files on the SD card. We only care about the cases in which
+the cores boot in AArch64 mode.
+
+The rules are simple:
+
+- If a file called ``kernel8.img`` is located on the ``boot`` partition of the
+  SD card, it will load it and execute in EL2 in AArch64. Basically, it executes
+  a `default AArch64 stub`_ at address **0x0** that jumps to the kernel.
+
+- If there is also a file called ``armstub8.bin``, it will load it at address
+  **0x0** (instead of the default stub) and execute it in EL3 in AArch64. All
+  the cores are powered on at the same time and start at address **0x0**.
+
+This means that we can use the default AArch32 kernel provided in the official
+`Raspbian`_ distribution by renaming it to ``kernel8.img``, while TF-A and
+anything else we need is in ``armstub8.bin``. This way we can forget about the
+default bootstrap code. When using a AArch64 kernel, it is only needed to make
+sure that the name on the SD card is ``kernel8.img``.
+
+Ideally, we want to load the kernel and have all cores available, which means
+that we need to make the secondary cores work in the way the kernel expects, as
+explained in `Secondary cores`_. In practice, a small bootstrap is needed
+between TF-A and the kernel.
+
+To get the most out of a AArch32 kernel, we want to boot it in Hypervisor mode
+in AArch32. This means that BL33 can't be in EL2 in AArch64 mode. The
+architecture specifies that AArch32 Hypervisor mode isn't present when AArch64
+is used for EL2. When using a AArch64 kernel, it should simply start in EL2.
+
+Placement of images
+~~~~~~~~~~~~~~~~~~~
+
+The file ``armstub8.bin`` contains BL1 and the FIP. It is needed to add padding
+between them so that the addresses they are loaded to match the ones specified
+when compiling TF-A. This is done automatically by the build system.
+
+The device tree block is loaded by the VideoCore loader from an appropriate
+file, but we can specify the address it is loaded to in ``config.txt``.
+
+The file ``kernel8.img`` contains a kernel image that is loaded to the address
+specified in ``config.txt``. The `Linux kernel tree`_ has information about how
+a AArch32 Linux kernel image is loaded in ``Documentation/arm/Booting``:
+
+::
+
+    The zImage may also be placed in system RAM and called there.  The
+    kernel should be placed in the first 128MiB of RAM.  It is recommended
+    that it is loaded above 32MiB in order to avoid the need to relocate
+    prior to decompression, which will make the boot process slightly
+    faster.
+
+There are no similar restrictions for AArch64 kernels, as specified in the file
+``Documentation/arm64/booting.txt``.
+
+This means that we need to avoid the first 128 MiB of RAM when placing the
+TF-A images (and specially the first 32 MiB, as they are directly used to
+place the uncompressed AArch32 kernel image. This way, both AArch32 and
+AArch64 kernels can be placed at the same address.
+
+In the end, the images look like the following diagram when placed in memory.
+All addresses are Physical Addresses from the point of view of the Arm cores.
+Again, note that this is all just part of the same DRAM that goes from
+**0x00000000** to **0x3F000000**, it just has different names to simulate a real
+secure platform!

+               |       I/O       |
+    0x40000000 +-----------------+
+
+The area between **0x10000000** and **0x11000000** has to be manually protected
+so that the kernel doesn't use it. The current port tries to modify the live DTB
+to add a memreserve region that reserves the previously mentioned area.
+
+If this is not possible, the user may manually add ``memmap=16M$256M`` to the
+command line passed to the kernel in ``cmdline.txt``. See the `Setup SD card`_
+instructions to see how to do it. This system is strongly discouraged.
+
+The last 16 MiB of DRAM can only be accessed by the VideoCore, that has
+different mappings than the Arm cores in which the I/O addresses don't overlap
+the DRAM. The memory reserved to be used by the VideoCore is always placed at
+the end of the DRAM, so this space isn't wasted.
+
+Considering the 128 MiB allocated to the GPU and the 16 MiB allocated for
+TF-A, there are 880 MiB available for Linux.
+
+Boot sequence
+~~~~~~~~~~~~~
+
+The boot sequence of TF-A is the usual one except when booting an AArch32
+kernel. In that case, BL33 is booted in AArch32 Hypervisor mode so that it
+can jump to the kernel in the same mode and let it take over that privilege
+level. If BL33 was running in EL2 in AArch64 (as in the default bootflow of
+TF-A) it could only jump to the kernel in AArch32 in Supervisor mode.
+
+The `Linux kernel tree`_ has instructions on how to jump to the Linux kernel
+in ``Documentation/arm/Booting`` and ``Documentation/arm64/booting.txt``. The
+bootstrap should take care of this.
+
+This port support a direct boot of the Linux kernel from the firmware (as a BL33
+image). Alternatively, U-Boot or other bootloaders may be used.
+
+Secondary cores
+~~~~~~~~~~~~~~~
+
+This port of the Trusted Firmware-A supports ``PSCI_CPU_ON``,
+``PSCI_SYSTEM_RESET`` and ``PSCI_SYSTEM_OFF``. The last one doesn't really turn
+the system off, it simply reboots it and asks the VideoCore firmware to keep it
+in a low power mode permanently.
+
+The kernel used by `Raspbian`_ doesn't have support for PSCI, so it is needed to
+use mailboxes to trap the secondary cores until they are ready to jump to the
+kernel. This mailbox is located at a different address in the AArch32 default
+kernel than in the AArch64 kernel.
+
+Kernels with PSCI support can use the PSCI calls instead for a cleaner boot.
+
+Also, this port of TF-A has another Trusted Mailbox in Shared BL RAM. During
+cold boot, all secondary cores wait in a loop until they are given given an
+address to jump to in this Mailbox (``bl31_warm_entrypoint``).
+
+Once BL31 has finished and the primary core has jumped to the BL33 payload, it
+has to call ``PSCI_CPU_ON`` to release the secondary CPUs from the wait loop.
+The payload then makes them wait in another waitloop listening from messages
+from the kernel. When the primary CPU jumps into the kernel, it will send an
+address to the mailbox so that the secondary CPUs jump to it and are recognised
+by the kernel.
+
+Build Instructions
+------------------
+
+To boot a AArch64 kernel, only the AArch64 toolchain is required.
+
+To boot a AArch32 kernel, both AArch64 and AArch32 toolchains are required. The
+AArch32 toolchain is needed for the AArch32 bootstrap needed to load a 32-bit
+kernel.
+
+The build system concatenates BL1 and the FIP so that the addresses match the
+ones in the memory map. The resulting file is ``armstub8.bin``, located in the
+build folder (e.g. ``build/rpi3/debug/armstub8.bin``). To know how to use this
+file, follow the instructions in `Setup SD card`_.
+
+The following build options are supported:
+
+- ``RPI3_BL33_IN_AARCH32``: This port can load a AArch64 or AArch32 BL33 image.
+  By default this option is 0, which means that TF-A will jump to BL33 in EL2
+  in AArch64 mode. If set to 1, it will jump to BL33 in Hypervisor in AArch32
+  mode.
+
+- ``PRELOADED_BL33_BASE``: Used to specify the address of a BL33 binary that has
+  been preloaded by any other system than using the firmware. ``BL33`` isn't
+  needed in the build command line if this option is used. Specially useful
+  because the file ``kernel8.img`` can be loaded anywhere by modifying the file
+  ``config.txt``. It doesn't have to contain a kernel, it could have any
+  arbitrary payload.
+
+- ``RPI3_DIRECT_LINUX_BOOT``: Disabled by default. Set to 1 to enable the direct
+  boot of the Linux kernel from the firmware. Option ``RPI3_PRELOADED_DTB_BASE``
+  is mandatory when the direct Linux kernel boot is used. Options
+  ``PRELOADED_BL33_BASE`` will most likely be needed as well because it is
+  unlikely that the kernel image will fit in the space reserved for BL33 images.
+  This option can be combined with ``RPI3_BL33_IN_AARCH32`` in order to boot a
+  32-bit kernel. The only thing this option does is to set the arguments in
+  registers x0-x3 or r0-r2 as expected by the kernel.
+
+- ``RPI3_PRELOADED_DTB_BASE``: Auxiliary build option needed when using
+  ``RPI3_DIRECT_LINUX_BOOT=1``. This option allows to specify the location of a
+  DTB in memory.
+
+- ``RPI3_RUNTIME_UART``: Indicates whether the UART should be used at runtime
+  or disabled. ``-1`` (default) disables the runtime UART. Any other value
+  enables the default UART (currently UART1) for runtime messages.
+
+- ``RPI3_USE_UEFI_MAP``: Set to 1 to build ATF with the altername memory
+  mapping required for an UEFI firmware payload. These changes are needed
+  to be able to run Windows on ARM64. This option, which is disabled by
+  default, results in the following memory mappings:

+- ``BL32``: This port can load and run OP-TEE. The OP-TEE image is optional.
+  Please use the code from `here <https://github.com/OP-TEE/optee_os>`__.
+  Build the Trusted Firmware with option ``BL32=tee-header_v2.bin
+  BL32_EXTRA1=tee-pager_v2.bin  BL32_EXTRA2=tee-pageable_v2.bin``
+  to put the binaries into the FIP.
+
+  .. warning::
+     If OP-TEE is used it may be needed to add the following options to the
+     Linux command line so that the USB driver doesn't use FIQs:
+     ``dwc_otg.fiq_enable=0 dwc_otg.fiq_fsm_enable=0 dwc_otg.nak_holdoff=0``.
+     This will unfortunately reduce the performance of the USB driver. It is
+     needed when using Raspbian, for example.
+
+- ``TRUSTED_BOARD_BOOT``: This port supports TBB. Set this option to 1 to enable
+  it. In order to use TBB, you might want to set ``GENERATE_COT=1`` to let the
+  contents of the FIP automatically signed by the build process. The ROT key
+  will be generated and output to ``rot_key.pem`` in the build directory. It is
+  able to set ROT_KEY to your own key in PEM format.  Also in order to build,
+  you need to clone mbed TLS from `here <https://github.com/ARMmbed/mbedtls>`__.
+  ``MBEDTLS_DIR`` must point at the mbed TLS source directory.
+
+- ``ENABLE_STACK_PROTECTOR``: Disabled by default. It uses the hardware RNG of
+  the board.
+
+The following is not currently supported:
+
+- AArch32 for TF-A itself.
+
+- ``EL3_PAYLOAD_BASE``: The reason is that you can already load anything to any
+  address by changing the file ``armstub8.bin``, so there's no point in using
+  TF-A in this case.
+
+- ``MULTI_CONSOLE_API=0``: The multi console API must be enabled. Note that the
+  crash console uses the internal 16550 driver functions directly in order to be
+  able to print error messages during early crashes before setting up the
+  multi console API.
+
+Building the firmware for kernels that don't support PSCI
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This is the case for the 32-bit image of Raspbian, for example. 64-bit kernels
+always support PSCI, but they may not know that the system understands PSCI due
+to an incorrect DTB file.
+
+First, clone and compile the 32-bit version of the `Raspberry Pi 3 TF-A
+bootstrap`_. Choose the one needed for the architecture of your kernel.
+
+Then compile TF-A. For a 32-bit kernel, use the following command line:
+
+.. code:: shell
+
+    CROSS_COMPILE=aarch64-linux-gnu- make PLAT=rpi3             \
+    RPI3_BL33_IN_AARCH32=1                                      \
+    BL33=../rpi3-arm-tf-bootstrap/aarch32/el2-bootstrap.bin
+
+For a 64-bit kernel, use this other command line:
+
+.. code:: shell
+
+    CROSS_COMPILE=aarch64-linux-gnu- make PLAT=rpi3             \
+    BL33=../rpi3-arm-tf-bootstrap/aarch64/el2-bootstrap.bin
+
+However, enabling PSCI support in a 64-bit kernel is really easy. In the
+repository `Raspberry Pi 3 TF-A bootstrap`_ there is a patch that can be applied
+to the Linux kernel tree maintained by the Raspberry Pi foundation. It modifes
+the DTS to tell the kernel to use PSCI. Once this patch is applied, follow the
+instructions in `AArch64 kernel build instructions`_ to get a working 64-bit
+kernel image and supporting files.
+
+Building the firmware for kernels that support PSCI
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+For a 64-bit kernel:
+
+.. code:: shell
+
+    CROSS_COMPILE=aarch64-linux-gnu- make PLAT=rpi3             \
+    PRELOADED_BL33_BASE=0x02000000                              \
+    RPI3_PRELOADED_DTB_BASE=0x01000000                          \
+    RPI3_DIRECT_LINUX_BOOT=1
+
+For a 32-bit kernel:
+
+.. code:: shell
+
+    CROSS_COMPILE=aarch64-linux-gnu- make PLAT=rpi3             \
+    PRELOADED_BL33_BASE=0x02000000                              \
+    RPI3_PRELOADED_DTB_BASE=0x01000000                          \
+    RPI3_DIRECT_LINUX_BOOT=1                                    \
+    RPI3_BL33_IN_AARCH32=1
+
+AArch64 kernel build instructions
+---------------------------------
+
+The following instructions show how to install and run a AArch64 kernel by
+using a SD card with the default `Raspbian`_ install as base. Skip them if you
+want to use the default 32-bit kernel.
+
+Note that this system won't be fully 64-bit because all the tools in the
+filesystem are 32-bit binaries, but it's a quick way to get it working, and it
+allows the user to run 64-bit binaries in addition to 32-bit binaries.
+
+1. Clone the `Linux tree fork`_ maintained by the Raspberry Pi Foundation. To
+   speed things up, do a shallow clone of the desired branch.
+
+.. code:: shell
+
+    git clone --depth=1 -b rpi-4.18.y https://github.com/raspberrypi/linux
+    cd linux
+
+2. Configure and compile the kernel. Adapt the number after ``-j`` so that it is
+   1.5 times the number of CPUs in your computer. This may take some time to
+   finish.
+
+.. code:: shell
+
+    make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- bcmrpi3_defconfig
+    make -j 6 ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu-
+
+3. Copy the kernel image and the device tree to the SD card. Replace the path
+   by the corresponding path in your computers to the ``boot`` partition of the
+   SD card.
+
+.. code:: shell
+
+    cp arch/arm64/boot/Image /path/to/boot/kernel8.img
+    cp arch/arm64/boot/dts/broadcom/bcm2710-rpi-3-b.dtb /path/to/boot/
+    cp arch/arm64/boot/dts/broadcom/bcm2710-rpi-3-b-plus.dtb /path/to/boot/
+
+4. Install the kernel modules. Replace the path by the corresponding path to the
+   filesystem partition of the SD card on your computer.
+
+.. code:: shell
+
+    make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- \
+    INSTALL_MOD_PATH=/path/to/filesystem modules_install
+
+5. Follow the instructions in `Setup SD card`_ except for the step of renaming
+   the existing ``kernel7.img`` (we have already copied a AArch64 kernel).
+
+Setup SD card
+-------------
+
+The instructions assume that you have an SD card with a fresh install of
+`Raspbian`_ (or that, at least, the ``boot`` partition is untouched, or nearly
+untouched). They have been tested with the image available in 2018-03-13.
+
+1. Insert the SD card and open the ``boot`` partition.
+
+2. Rename ``kernel7.img`` to ``kernel8.img``. This tricks the VideoCore
+   bootloader into booting the Arm cores in AArch64 mode, like TF-A needs,
+   even though the kernel is not compiled for AArch64.
+
+3. Copy ``armstub8.bin`` here. When ``kernel8.img`` is available, The VideoCore
+   bootloader will look for a file called ``armstub8.bin`` and load it at
+   address **0x0** instead of a predefined one.
+
+4. To enable the serial port "Mini UART" in Linux, open ``cmdline.txt`` and add
+   ``console=serial0,115200 console=tty1``.
+
+5. Open ``config.txt`` and add the following lines at the end (``enable_uart=1``
+   is only needed to enable debugging through the Mini UART):
+
+::
+
+    enable_uart=1
+    kernel_address=0x02000000
+    device_tree_address=0x01000000
+
+If you connect a serial cable to the Mini UART and your computer, and connect
+to it (for example, with ``screen /dev/ttyUSB0 115200``) you should see some
+text. In the case of an AArch32 kernel, you should see something like this:

+Raspberry Pi 4
+==============
+
+The `Raspberry Pi 4`_ is an inexpensive single-board computer that contains four
+Arm Cortex-A72 cores. Also in contrast to previous Raspberry Pi versions this
+model has a GICv2 interrupt controller.
+
+This port is a minimal port to support loading non-secure EL2 payloads such
+as a 64-bit Linux kernel. Other payloads such as U-Boot or EDK-II should work
+as well, but have not been tested at this point.
+
+**IMPORTANT NOTE**: This port isn't secure. All of the memory used is DRAM,
+which is available from both the Non-secure and Secure worlds. The SoC does
+not seem to feature a secure memory controller of any kind, so portions of
+DRAM can't be protected properly from the Non-secure world.
+
+Build Instructions
+------------------
+
+There are no real configuration options at this point, so there is only
+one universal binary (bl31.bin), which can be built with:
+
+.. code:: shell
+
+    CROSS_COMPILE=aarch64-linux-gnu- make PLAT=rpi4 DEBUG=1
+
+Copy the generated build/rpi4/debug/bl31.bin to the SD card, adding an entry
+starting with ``armstub=``, then followed by the respective file name to
+``config.txt``. You should have AArch64 code in the file loaded as the
+"kernel", as BL31 will drop into AArch64/EL2 to the respective load address.
+arm64 Linux kernels are known to work this way.
+
+Other options that should be set in ``config.txt`` to properly boot 64-bit
+kernels are:
+
+::
+
+    enable_uart=1
+    arm_64bit=1
+    enable_gic=1
+
+The BL31 code will patch the provided device tree blob in memory to advertise
+PSCI support, also will add a reserved-memory node to the DT to tell the
+non-secure payload to not touch the resident TF-A code.
+
+If you connect a serial cable between the Mini UART and your computer, and
+connect to it (for example, with ``screen /dev/ttyUSB0 115200``) you should
+see some text from BL31, followed by the output of the EL2 payload.
+The command line provided is read from the ``cmdline.txt`` file on the SD card.
+
+TF-A port design
+----------------
+
+In contrast to the existing Raspberry Pi 3 port this one here is a BL31-only
+port, also it deviates quite a lot from the RPi3 port in many other ways.
+There is not so much difference between the two models, so eventually those
+two could be (more) unified in the future.
+
+As with the previous models, the GPU and its firmware are the first entity to
+run after the SoC gets its power. The on-chip Boot ROM loads the next stage
+(bootcode.bin) from flash (EEPROM), which is again GPU code.
+This part knows how to access the MMC controller and how to parse a FAT
+filesystem, so it will load further components and configuration files
+from the first FAT partition on the SD card.
+
+To accommodate this existing way of configuring and setting up the board,
+we use as much of this workflow as possible.
+If bootcode.bin finds a file called ``armstub8.bin`` on the SD card or it gets
+pointed to such code by finding a ``armstub=`` key in ``config.txt``, it will
+load this file to the beginning of DRAM (address 0) and execute it in
+AArch64 EL3.
+But before doing that, it will also load a "kernel" and the device tree into
+memory. The load addresses have a default, but can also be changed by
+setting them in ``config.txt``. If the GPU firmware finds a magic value in the
+armstub image file, it will put those two load addresses in memory locations
+near the beginning of memory, where TF-A code picks them up.
+
+To keep things simple, we will just use the kernel load address as the BL33
+entry point, also put the DTB address in the x0 register, as requested by
+the arm64 Linux kernel boot protocol. This does not necessarily mean that
+the EL2 payload needs to be a Linux kernel, a bootloader or any other kernel
+would work as well, as long as it can cope with having the DT address in
+register x0. If the payload has other means of finding the device tree, it
+could ignore this address as well.

+Overview
+--------
+On RZ/G2 SoCs the BOOTROM starts the cpu at EL3; for this port BL2
+will therefore be entered at this exception level (the Renesas' ATF
+reference tree [1] resets into EL1 before entering BL2 - see its
+bl2.ld.S)
+
+BL2 initializes DDR before determining the boot reason (cold or warm).
+
+Once BL2 boots, it determines the boot reason, writes it to shared
+memory (BOOT_KIND_BASE) together with the BL31 parameters
+(PARAMS_BASE) and jumps to BL31.
+
+To all effects, BL31 is as if it is being entered in reset mode since
+it still needs to initialize the rest of the cores; this is the reason
+behind using direct shared memory access to  BOOT_KIND_BASE _and_
+PARAMS_BASE instead of using registers to get to those locations (see
+el3_common_macros.S and bl31_entrypoint.S for the RESET_TO_BL31 use
+case).

+Socionext UniPhier
+==================
+
+Socionext UniPhier Armv8-A SoCs use Trusted Firmware-A (TF-A) as the secure
+world firmware, supporting BL2 and BL31.
+
+UniPhier SoC family implements its internal boot ROM, which loads 64KB [1]_
+image from a non-volatile storage to the on-chip SRAM, and jumps over to it.
+TF-A provides a special mode, BL2-AT-EL3, which enables BL2 to execute at EL3.
+It is useful for platforms with non-TF-A boot ROM, like UniPhier. Here, a
+problem is BL2 does not fit in the 64KB limit if
+:ref:`Trusted Board Boot (TBB) <Trusted Board Boot>` is enabled.
+To solve this issue, Socionext provides a first stage loader called
+`UniPhier BL`_. This loader runs in the on-chip SRAM, initializes the DRAM,
+expands BL2 there, and hands the control over to it. Therefore, all images
+of TF-A run in DRAM.
+
+The UniPhier platform works with/without TBB. See below for the build process
+of each case. The image authentication for the UniPhier platform fully
+complies with the Trusted Board Boot Requirements (TBBR) specification.
+
+The UniPhier BL does not implement the authentication functionality, that is,
+it can not verify the BL2 image by itself. Instead, the UniPhier BL assures
+the BL2 validity in a different way; BL2 is GZIP-compressed and appended to
+the UniPhier BL. The concatenation of the UniPhier BL and the compressed BL2
+fits in the 64KB limit. The concatenated image is loaded by the internal boot
+ROM (and verified if the chip fuses are blown).
+
+
+Boot Flow
+---------
+
+1. The Boot ROM
+
+   This is hard-wired ROM, so never corrupted. It loads the UniPhier BL (with
+   compressed-BL2 appended) into the on-chip SRAM. If the SoC fuses are blown,
+   the image is verified by the SoC's own method.
+
+2. UniPhier BL
+
+   This runs in the on-chip SRAM. After the minimum SoC initialization and DRAM
+   setup, it decompresses the appended BL2 image into the DRAM, then jumps to
+   the BL2 entry.
+
+3. BL2 (at EL3)
+
+   This runs in the DRAM. It extracts more images such as BL31, BL33 (optionally
+   SCP_BL2, BL32 as well) from Firmware Image Package (FIP). If TBB is enabled,
+   they are all authenticated by the standard mechanism of TF-A.
+   After loading all the images, it jumps to the BL31 entry.
+
+4. BL31, BL32, and BL33
+
+   They all run in the DRAM. See :ref:`Firmware Design` for details.
+
+
+Basic Build
+-----------
+
+BL2 must be compressed for the reason above. The UniPhier's platform makefile
+provides a build target ``bl2_gzip`` for this.
+
+For a non-secure boot loader (aka BL33), U-Boot is well supported for UniPhier
+SoCs. The U-Boot image (``u-boot.bin``) must be built in advance. For the build
+procedure of U-Boot, refer to the document in the `U-Boot`_ project.
+
+To build minimum functionality for UniPhier (without TBB)::
+
+    make CROSS_COMPILE=<gcc-prefix> PLAT=uniphier BL33=<path-to-BL33> bl2_gzip fip
+
+Output images:
+
+- ``bl2.bin.gz``
+- ``fip.bin``
+
+
+Optional features
+-----------------
+
+- Trusted Board Boot
+
+  `mbed TLS`_ is needed as the cryptographic and image parser modules.
+  Refer to the :ref:`Prerequisites` document for the appropriate version of
+  mbed TLS.
+
+  To enable TBB, add the following options to the build command::
+
+      TRUSTED_BOARD_BOOT=1 GENERATE_COT=1 MBEDTLS_DIR=<path-to-mbedtls>
+
+- System Control Processor (SCP)
+
+  If desired, FIP can include an SCP BL2 image. If BL2 finds an SCP BL2 image
+  in FIP, BL2 loads it into DRAM and kicks the SCP. Most of UniPhier boards
+  still work without SCP, but SCP provides better power management support.
+
+  To include SCP BL2, add the following option to the build command::
+
+      SCP_BL2=<path-to-SCP>
+
+- BL32 (Secure Payload)
+
+  To enable BL32, add the following options to the build command::
+
+      SPD=<spd> BL32=<path-to-BL32>
+
+  If you use TSP for BL32, ``BL32=<path-to-BL32>`` is not required. Just add the
+  following::
+
+      SPD=tspd
+
+
+.. [1] Some SoCs can load 80KB, but the software implementation must be aligned
+   to the lowest common denominator.

+STMicroelectronics STM32MP1
+===========================
+
+STM32MP1 is a microprocessor designed by STMicroelectronics
+based on Arm Cortex-A7.
+It is an Armv7-A platform, using dedicated code from TF-A.
+More information can be found on `STM32MP1 Series`_ page.
+
+
+STM32MP1 Versions
+-----------------
+
+There are 2 variants for STM32MP1: STM32MP13 and STM32MP15
+
+STM32MP13 Versions
+~~~~~~~~~~~~~~~~~~
+The STM32MP13 series is available in 3 different lines which are pin-to-pin compatible:
+
+- STM32MP131: Single Cortex-A7 core
+- STM32MP133: STM32MP131 + 2*CAN, ETH2(GMAC), ADC1
+- STM32MP135: STM32MP133 + DCMIPP, LTDC
+
+Each line comes with a security option (cryptography & secure boot) and a Cortex-A frequency option:
+
+- A      Cortex-A7 @ 650 MHz
+- C      Secure Boot + HW Crypto + Cortex-A7 @ 650 MHz
+- D      Cortex-A7 @ 900 MHz
+- F      Secure Boot + HW Crypto + Cortex-A7 @ 900 MHz
+
+STM32MP15 Versions
+~~~~~~~~~~~~~~~~~~
+The STM32MP15 series is available in 3 different lines which are pin-to-pin compatible:
+
+- STM32MP157: Dual Cortex-A7 cores, Cortex-M4 core @ 209 MHz, 3D GPU, DSI display interface and CAN FD
+- STM32MP153: Dual Cortex-A7 cores, Cortex-M4 core @ 209 MHz and CAN FD
+- STM32MP151: Single Cortex-A7 core, Cortex-M4 core @ 209 MHz
+
+Each line comes with a security option (cryptography & secure boot) and a Cortex-A frequency option:
+
+- A      Basic + Cortex-A7 @ 650 MHz
+- C      Secure Boot + HW Crypto + Cortex-A7 @ 650 MHz
+- D      Basic + Cortex-A7 @ 800 MHz
+- F      Secure Boot + HW Crypto + Cortex-A7 @ 800 MHz
+
+The `STM32MP1 part number codification`_ page gives more information about part numbers.
+
+Design
+------
+The STM32MP1 resets in the ROM code of the Cortex-A7.
+The primary boot core (core 0) executes the boot sequence while
+secondary boot core (core 1) is kept in a holding pen loop.
+The ROM code boot sequence loads the TF-A binary image from boot device
+to embedded SRAM.
+
+The TF-A image must be properly formatted with a STM32 header structure
+for ROM code is able to load this image.
+Tool stm32image can be used to prepend this header to the generated TF-A binary.
+
+Boot with FIP
+~~~~~~~~~~~~~
+The use of FIP is now the recommended way to boot STM32MP1 platform.
+Only BL2 (with STM32 header) is loaded by ROM code. The other binaries are
+inside the FIP binary: BL32 (SP_min or OP-TEE), U-Boot and their respective
+device tree blobs.

+
+Boot with FIP
+~~~~~~~~~~~~~
+You need to build BL2, BL32 (SP_min or OP-TEE) and BL33 (U-Boot) before building FIP binary.
+
+U-Boot
+______
+
+.. code:: bash
+
+    cd <u-boot_directory>
+    make stm32mp15_trusted_defconfig
+    make DEVICE_TREE=stm32mp157c-ev1 all

+
+
+TF-A BL32 (SP_min)
+__________________
+If you choose not to use OP-TEE, you can use TF-A SP_min.
+To build TF-A BL32, and its device tree file:
+
+.. code:: bash
+
+    make CROSS_COMPILE=arm-none-eabi- PLAT=stm32mp1 ARCH=aarch32 ARM_ARCH_MAJOR=7 \
+        AARCH32_SP=sp_min DTB_FILE_NAME=stm32mp157c-ev1.dtb bl32 dtbs
+
+TF-A BL2
+________
+To build TF-A BL2 with its STM32 header for SD-card boot:
+
+.. code:: bash
+
+    make CROSS_COMPILE=arm-none-eabi- PLAT=stm32mp1 ARCH=aarch32 ARM_ARCH_MAJOR=7 \
+        DTB_FILE_NAME=stm32mp157c-ev1.dtb STM32MP_SDMMC=1
+
+For other boot devices, you have to replace STM32MP_SDMMC in the previous command
+with the desired device flag.
+
+This BL2 is independent of the BL32 used (SP_min or OP-TEE)
+
+
+FIP

+
+Build Procedure
+~~~~~~~~~~~~~~~
+
+-  Firstly, in addition to the “normal� build tools you will also need a

+   this directory is created but as an example:
+
+   .. code:: shell
+
+       export WORKSPACE=$HOME/build/developerbox-firmware
+       mkdir -p $WORKSPACE
+
+-  Run the following commands to clone the source code:

+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+-  Providing your Developerbox is fully working and has on operating system

+
+   .. code:: shell
+
+       sudo apt install fwupdate
+       sudo fwupdate --apply {50b94ce5-8b63-4849-8af4-ea479356f0e3} \
+                     SYNQUACERFIRMWAREUPDATECAPSULEFMPPKCS7.Cap
+       sudo reboot
+
+-  Alternatively you can install SPI_NOR_IMAGE.fd using the `board recovery method`_.

+NXP i.MX7 WaRP7
+===============
+
+The Trusted Firmware-A port for the i.MX7Solo WaRP7 implements BL2 at EL3.
+The i.MX7S contains a BootROM with a High Assurance Boot (HAB) functionality.
+This functionality provides a mechanism for establishing a root-of-trust from
+the reset vector to the command-line in user-space.
+
+Boot Flow
+---------
+
+BootROM --> TF-A BL2 --> BL32(OP-TEE) --> BL33(U-Boot) --> Linux
+
+In the WaRP7 port we encapsulate OP-TEE, DTB and U-Boot into a FIP. This FIP is
+expected and required
+
+Build Instructions
+------------------
+
+We need to use a file generated by u-boot in order to generate a .imx image the
+BootROM will boot. It is therefore _required_ to build u-boot before TF-A and
+furthermore it is _recommended_ to use the mkimage in the u-boot/tools directory
+to generate the TF-A .imx image.

+
+Deploy Images
+-------------
+
+First place the WaRP7 into UMS mode in u-boot this should produce an entry in
+/dev like /dev/disk/by-id/usb-Linux_UMS_disk_0_WaRP7-0xf42400d3000001d4-0\:0
+
+.. code:: shell
+
+    => ums 0 mmc 0
+
+Next flash bl2.imx and warp7.fip
+
+bl2.imx is flashed @ 1024 bytes
+warp7.fip is flash @ 1048576 bytes
+
+.. code:: shell
+
+    sudo dd if=bl2.bin.imx of=/dev/disk/by-id/usb-Linux_UMS_disk_0_WaRP7-0xf42400d3000001d4-0\:0 bs=512 seek=2 conv=notrunc
+    # Offset is 1MB 1048576 => 1048576 / 512 = 2048
+    sudo dd if=./warp7.fip of=/dev/disk/by-id/usb-Linux_UMS_disk_0_WaRP7-0xf42400d3000001d4-0\:0 bs=512 seek=2048 conv=notrunc
+
+Remember to umount the USB device pefore proceeding
+
+.. code:: shell
+
+    sudo umount /dev/disk/by-id/usb-Linux_UMS_disk_0_WaRP7-0xf42400d3000001d4-0\:0*
+
+
+Signing BL2
+-----------
+
+A further step is to sign BL2.
+
+The image_sign.sh and bl2_sign.csf files alluded to blow are available here.
+
+https://github.com/bryanodonoghue/atf-code-signing
+
+It is suggested you use this script plus the example CSF file in order to avoid
+hard-coding data into your CSF files.
+
+Download both "image_sign.sh" and "bl2_sign.csf" to your
+arm-trusted-firmware top-level directory.
+
+.. code:: shell
+
+    #!/bin/bash
+    SIGN=image_sign.sh
+    TEMP=`pwd`/temp
+    BL2_CSF=bl2_sign.csf
+    BL2_IMX=bl2.bin.imx
+    CST_PATH=/path/to/cst-2.3.2
+    CST_BIN=${CST_PATH}/linux64/cst
+
+    #Remove temp
+    rm -rf ${TEMP}
+    mkdir ${TEMP}
+
+    # Generate IMX header
+    /path/to/u-boot/tools/mkimage -n u-boot.cfgout.warp7 -T imximage -e 0x9df00000 -d ./build/warp7/debug/bl2.bin ./build/warp7/debug/bl2.bin.imx > ${TEMP}/${BL2_IMX}.log
+
+    # Copy required items to $TEMP
+    cp build/warp7/debug/bl2.bin.imx ${TEMP}
+    cp ${CST_PATH}/keys/* ${TEMP}
+    cp ${CST_PATH}/crts/* ${TEMP}
+    cp ${BL2_CSF} ${TEMP}
+
+    # Generate signed BL2 image
+    ./${SIGN} image_sign_mbl_binary ${TEMP} ${BL2_CSF} ${BL2_IMX} ${CST_BIN}
+
+    # Copy signed BL2 to top-level directory
+    cp ${TEMP}/${BL2_IMX}-signed .
+    cp ${BL2_RECOVER_CSF} ${TEMP}
+
+
+The resulting bl2.bin.imx-signed can replace bl2.bin.imx in the Deploy
+Images section above, once done.
+
+Suggested flow for verifying.
+
+1. Followed all previous steps above and verify a non-secure ATF boot
+2. Down the NXP Code Singing Tool
+3. Generate keys
+4. Program the fuses on your board
+5. Replace bl2.bin.imx with bl2.bin.imx-signed
+6. Verify inside u-boot that "hab_status" shows no events
+7. Subsequently close your board.
+
+If you have HAB events @ step 6 - do not lock your board.
+
+To get a good over-view of generating keys and programming the fuses on the
+board read "High Assurance Boot for Dummies" by Boundary Devices.

+Code Review Guidelines
+======================
+
+This document provides TF-A specific details about the project's code review
+process. It should be read in conjunction with the `Project Maintenance
+Process`_, which it supplements.
+
+
+Why do we do code reviews?
+--------------------------
+
+The main goal of code reviews is to improve the code quality. By reviewing each
+other's code, we can help catch issues that were missed by the author
+before they are integrated in the source tree. Different people bring different
+perspectives, depending on their past work, experiences and their current use
+cases of TF-A in their products.
+
+Code reviews also play a key role in sharing knowledge within the
+community. People with more expertise in one area of the code base can
+help those that are less familiar with it.
+
+Code reviews are meant to benefit everyone through team work. It is not about
+unfairly criticizing or belittling the work of any contributor.
+
+
+Good practices
+--------------
+
+To ensure the code review gives the greatest possible benefit, participants in
+the project should:
+
+-  Be considerate of other people and their needs. Participants may be working
+   to different timescales, and have different priorities. Keep this in
+   mind - be gracious while waiting for action from others, and timely in your
+   actions when others are waiting for you.
+
+-  Review other people's patches where possible. The more active reviewers there
+   are, the more quickly new patches can be reviewed and merged. Contributing to
+   code review helps everyone in the long run, as it creates a culture of
+   participation which serves everyone's interests.
+
+
+Guidelines for patch contributors
+---------------------------------
+
+In addition to the rules outlined in the :ref:`Contributor's Guide`, as a patch
+contributor you are expected to:
+
+-  Answer all comments from people who took the time to review your
+   patches.
+
+-  Be patient and resilient. It is quite common for patches to go through
+   several rounds of reviews and rework before they get approved, especially
+   for larger features.
+
+   In the event that a code review takes longer than you would hope for, you
+   may try the following actions to speed it up:
+
+  -  Ping the reviewers on Gerrit or on the mailing list. If it is urgent,
+     explain why. Please remain courteous and do not abuse this.
+
+  -  If one code owner has become unresponsive, ask the other code owners for
+     help progressing the patch.
+
+  -  If there is only one code owner and they have become unresponsive, ask one
+     of the project maintainers for help.
+
+-  Do the right thing for the project, not the fastest thing to get code merged.
+
+   For example, if some existing piece of code - say a driver - does not quite
+   meet your exact needs, go the extra mile and extend the code with the missing
+   functionality you require - as opposed to copying the code into some other
+   directory to have the freedom to change it in any way. This way, your changes
+   benefit everyone and will be maintained over time.
+
+
+Guidelines for all reviewers
+----------------------------
+
+There are no good or bad review comments. If you have any doubt about a patch or
+need some clarifications, it's better to ask rather than letting a potential
+issue slip. Examples of review comments could be:
+
+- Questions ("Why do you need to do this?", "What if X happens?")
+- Bugs ("I think you need a logical \|\| rather than a bitwise \|.")
+- Design issues ("This won't scale well when we introduce feature X.")
+- Improvements ("Would it be better if we did Y instead?")
+
+
+Guidelines for code owners
+--------------------------
+
+Code owners are listed on the :ref:`Project Maintenance<code owners>` page,
+along with the module(s) they look after.
+
+When reviewing a patch, code owners are expected to check the following:
+
+-  The patch looks good from a technical point of view. For example:
+
+  -  The structure of the code is clear.
+
+  -  It complies with the relevant standards or technical documentation (where
+     applicable).
+
+  -  It leverages existing interfaces rather than introducing new ones
+     unnecessarily.
+
+  -  It fits well in the design of the module.
+
+  -  It adheres to the security model of the project. In particular, it does not
+     increase the attack surface (e.g. new SMCs) without justification.
+
+-  The patch adheres to the TF-A :ref:`Coding Style`. The CI system should help
+   catch coding style violations.
+
+-  (Only applicable to generic code) The code is MISRA-compliant (see
+   :ref:`misra-compliance`). The CI system should help catch violations.
+
+-  Documentation is provided/updated (where applicable).
+
+-  The patch has had an appropriate level of testing. Testing details are
+   expected to be provided by the patch author. If they are not, do not hesitate
+   to request this information.
+
+-  All CI automated tests pass.
+
+If a code owner is happy with a patch, they should give their approval
+through the ``Code-Owner-Review+1`` label in Gerrit. If instead, they have
+concerns, questions, or any other type of blocking comment, they should set
+``Code-Owner-Review-1``.
+
+Code owners are expected to behave professionally and responsibly. Here are some
+guidelines for them:
+
+-  Once you are engaged in a review, make sure you stay involved until the patch
+   is merged. Rejecting a patch and going away is not very helpful. You are
+   expected to monitor the patch author's answers to your review comments,
+   answer back if needed and review new revisions of their patch.
+
+-  Provide constructive feedback. Just saying, "This is wrong, you should do X
+   instead." is usually not very helpful. The patch author is unlikely to
+   understand why you are requesting this change and might feel personally
+   attacked.
+
+-  Be mindful when reviewing a patch. As a code owner, you are viewed as
+   the expert for the relevant module. By approving a patch, you are partially
+   responsible for its quality and the effects it has for all TF-A users. Make
+   sure you fully understand what the implications of a patch might be.
+
+
+Guidelines for maintainers
+--------------------------
+
+Maintainers are listed on the :ref:`Project Maintenance<maintainers>` page.
+
+When reviewing a patch, maintainers are expected to check the following:
+
+-  The general structure of the patch looks good. This covers things like:
+
+   -  Code organization.
+
+   -  Files and directories, names and locations.
+
+      For example, platform code should be added under the ``plat/`` directory.
+
+   -  Naming conventions.
+
+      For example, platform identifiers should be properly namespaced to avoid
+      name clashes with generic code.
+
+   -  API design.
+
+-  Interaction of the patch with other modules in the code base.
+
+-  The patch aims at complying with any standard or technical documentation
+   that applies.
+
+-  New files must have the correct license and copyright headers. See :ref:`this
+   paragraph<copyright-license-guidance>` for more information. The CI system
+   should help catch files with incorrect or no copyright/license headers.
+
+-  There is no third party code or binary blobs with potential IP concerns.
+   Maintainers should look for copyright or license notices in code, and use
+   their best judgement. If they are unsure about a patch, they should ask
+   other maintainers for help.
+
+-  Generally speaking, new driver code should be placed in the generic
+   layer. There are cases where a driver has to stay into the platform layer but
+   this should be the exception, rather than the rule.
+
+-  Existing common drivers (in particular for Arm IPs like the GIC driver) should
+   not be copied into the platform layer to cater for platform quirks. This
+   type of code duplication hurts the maintainability of the project. The
+   duplicate driver is less likely to benefit from bug fixes and future
+   enhancements. In most cases, it is possible to rework a generic driver to
+   make it more flexible and fit slightly different use cases. That way, these
+   enhancements benefit everyone.
+
+-  When a platform specific driver really is required, the burden lies with the
+   patch author to prove the need for it. A detailed justification should be
+   posted via the commit message or on the mailing list.
+
+-  Before merging a patch, verify that all review comments have been addressed.
+   If this is not the case, encourage the patch author and the relevant
+   reviewers to resolve these together.
+
+If a maintainer is happy with a patch, they should give their approval
+through the ``Maintainer-Review+1`` label in Gerrit. If instead, they have
+concerns, questions, or any other type of blocking comment, they should set
+``Maintainer-Review-1``.

+Coding Guidelines
+=================
+
+This document provides some additional guidelines to consider when writing
+|TF-A| code. These are not intended to be strictly-enforced rules like the
+contents of the :ref:`Coding Style`.
+
+Automatic Editor Configuration
+------------------------------
+
+Many of the rules given below (such as indentation size, use of tabs, and
+newlines) can be set automatically using the `EditorConfig`_ configuration file
+in the root of the repository: ``.editorconfig``. With a supported editor, the
+rules set out in this file can be automatically applied when you are editing
+files in the |TF-A| repository.
+
+Several editors include built-in support for EditorConfig files, and many others
+support its functionality through plugins.
+
+Use of the EditorConfig file is suggested but is not required.
+
+.. _automatic-compliance-checking:
+
+Automatic Compliance Checking
+-----------------------------
+
+To assist with coding style compliance, the project Makefile contains two
+targets which both utilise the `checkpatch.pl` script that ships with the Linux
+source tree. The project also defines certain *checkpatch* options in the
+``.checkpatch.conf`` file in the top-level directory.
+
+.. note::
+   Checkpatch errors will gate upstream merging of pull requests.
+   Checkpatch warnings will not gate merging but should be reviewed and fixed if
+   possible.
+
+To check the entire source tree, you must first download copies of
+``checkpatch.pl``, ``spelling.txt`` and ``const_structs.checkpatch`` available
+in the `Linux master tree`_ *scripts* directory, then set the ``CHECKPATCH``
+environment variable to point to ``checkpatch.pl`` (with the other 2 files in
+the same directory) and build the `checkcodebase` target:
+
+.. code:: shell
+
+    make CHECKPATCH=<path-to-linux>/linux/scripts/checkpatch.pl checkcodebase
+
+To just check the style on the files that differ between your local branch and
+the remote master, use:
+
+.. code:: shell
+
+    make CHECKPATCH=<path-to-linux>/linux/scripts/checkpatch.pl checkpatch
+
+If you wish to check your patch against something other than the remote master,
+set the ``BASE_COMMIT`` variable to your desired branch. By default,
+``BASE_COMMIT`` is set to ``origin/master``.
+
+Ignored Checkpatch Warnings
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Some checkpatch warnings in the TF codebase are deliberately ignored. These
+include:
+
+- ``**WARNING: line over 80 characters**``: Although the codebase should
+  generally conform to the 80 character limit this is overly restrictive in some
+  cases.
+
+- ``**WARNING: Use of volatile is usually wrong``: see
+  `Why the “volatile� type class should not be used`_ . Although this document
+  contains some very useful information, there are several legimate uses of the
+  volatile keyword within the TF codebase.
+
+Performance considerations
+--------------------------
+
+Avoid printf and use logging macros
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+``debug.h`` provides logging macros (for example, ``WARN`` and ``ERROR``)
+which wrap ``tf_log`` and which allow the logging call to be compiled-out
+depending on the ``make`` command. Use these macros to avoid print statements
+being compiled unconditionally into the binary.
+
+Each logging macro has a numerical log level:
+
+.. code:: c
+
+  #define LOG_LEVEL_NONE    0
+  #define LOG_LEVEL_ERROR   10
+  #define LOG_LEVEL_NOTICE  20
+  #define LOG_LEVEL_WARNING 30
+  #define LOG_LEVEL_INFO    40
+  #define LOG_LEVEL_VERBOSE 50
+
+By default, all logging statements with a log level ``<= LOG_LEVEL_INFO`` will
+be compiled into debug builds and all statements with a log level
+``<= LOG_LEVEL_NOTICE`` will be compiled into release builds. This can be
+overridden from the command line or by the platform makefile (although it may be
+necessary to clean the build directory first).
+
+For example, to enable ``VERBOSE`` logging on FVP:
+
+.. code:: shell
+
+  make PLAT=fvp LOG_LEVEL=50 all
+
+Use const data where possible
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+For example, the following code:
+
+.. code:: c
+
+  struct my_struct {
+          int arg1;
+          int arg2;
+  };
+
+  void init(struct my_struct *ptr);
+
+  void main(void)
+  {
+          struct my_struct x;
+          x.arg1 = 1;
+          x.arg2 = 2;
+          init(&x);
+  }
+
+is better written as:
+
+.. code:: c
+
+  struct my_struct {
+          int arg1;
+          int arg2;
+  };
+
+  void init(const struct my_struct *ptr);
+
+  void main(void)
+  {
+          const struct my_struct x = { 1, 2 };
+          init(&x);
+  }
+
+This allows the linker to put the data in a read-only data section instead of a
+writeable data section, which may result in a smaller and faster binary. Note
+that this may require dependent functions (``init()`` in the above example) to
+have ``const`` arguments, assuming they don't need to modify the data.
+
+Libc functions that are banned or to be used with caution
+---------------------------------------------------------
+
+Below is a list of functions that present security risks and either must not be
+used (Banned) or are discouraged from use and must be used with care (Caution).
+
++------------------------+-----------+--------------------------------------+
+|    libc function       | Status    | Comments                             |
++========================+===========+======================================+
+| ``strcpy, wcscpy``,    | Banned    | use strlcpy instead                  |
+| ``strncpy``            |           |                                      |
++------------------------+-----------+--------------------------------------+
+| ``strcat, wcscat``,    | Banned    | use strlcat instead                  |
+| ``strncat``            |           |                                      |
++------------------------+-----------+--------------------------------------+
+| ``sprintf, vsprintf``  | Banned    | use snprintf, vsnprintf              |

++------------------------+-----------+--------------------------------------+

++------------------------+-----------+--------------------------------------+
+| ``vsnprintf``          | Caution   | inspect va_list match types          |
+|                        |           | specified in format string           |
++------------------------+-----------+--------------------------------------+

++------------------------+-----------+--------------------------------------+
+| ``*toa``               | Banned    | Use snprintf instead                 |
++------------------------+-----------+--------------------------------------+
+
+The `libc` component in the codebase will not add support for the banned APIs.
+
+Error handling and robustness
+-----------------------------
+
+Using CASSERT to check for compile time data errors
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Where possible, use the ``CASSERT`` macro to check the validity of data known at
+compile time instead of checking validity at runtime, to avoid unnecessary
+runtime code.
+
+For example, this can be used to check that the assembler's and compiler's views
+of the size of an array is the same.
+
+.. code:: c
+
+  #include <cassert.h>
+
+  define MY_STRUCT_SIZE 8 /* Used by assembler source files */
+
+  struct my_struct {
+      uint32_t arg1;
+      uint32_t arg2;
+  };
+
+  CASSERT(MY_STRUCT_SIZE == sizeof(struct my_struct), assert_my_struct_size_mismatch);
+
+
+If ``MY_STRUCT_SIZE`` in the above example were wrong then the compiler would
+emit an error like this:
+
+::
+
+  my_struct.h:10:1: error: size of array ‘assert_my_struct_size_mismatch’ is negative
+
+
+Using assert() to check for programming errors
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+In general, each secure world TF image (BL1, BL2, BL31 and BL32) should be
+treated as a tightly integrated package; the image builder should be aware of
+and responsible for all functionality within the image, even if code within that
+image is provided by multiple entities. This allows us to be more aggressive in
+interpreting invalid state or bad function arguments as programming errors using
+``assert()``, including arguments passed across platform porting interfaces.
+This is in contrast to code in a Linux environment, which is less tightly
+integrated and may attempt to be more defensive by passing the error back up the
+call stack.
+
+Where possible, badly written TF code should fail early using ``assert()``. This
+helps reduce the amount of untested conditional code. By default these
+statements are not compiled into release builds, although this can be overridden
+using the ``ENABLE_ASSERTIONS`` build flag.
+
+Examples:
+
+- Bad argument supplied to library function
+- Bad argument provided by platform porting function
+- Internal secure world image state is inconsistent
+
+
+Handling integration errors
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Each secure world image may be provided by a different entity (for example, a
+Trusted Boot vendor may provide the BL2 image, a TEE vendor may provide the BL32
+image and the OEM/SoC vendor may provide the other images).
+
+An image may contain bugs that are only visible when the images are integrated.
+The system integrator may not even have access to the debug variants of all the
+images in order to check if asserts are firing. For example, the release variant
+of BL1 may have already been burnt into the SoC. Therefore, TF code that detects
+an integration error should _not_ consider this a programming error, and should
+always take action, even in release builds.
+
+If an integration error is considered non-critical it should be treated as a
+recoverable error. If the error is considered critical it should be treated as
+an unexpected unrecoverable error.
+
+Handling recoverable errors
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The secure world **must not** crash when supplied with bad data from an external
+source. For example, data from the normal world or a hardware device. Similarly,
+the secure world **must not** crash if it detects a non-critical problem within
+itself or the system. It must make every effort to recover from the problem by
+emitting a ``WARN`` message, performing any necessary error handling and
+continuing.
+
+Examples:
+
+- Secure world receives SMC from normal world with bad arguments.
+- Secure world receives SMC from normal world at an unexpected time.
+- BL31 receives SMC from BL32 with bad arguments.
+- BL31 receives SMC from BL32 at unexpected time.
+- Secure world receives recoverable error from hardware device. Retrying the
+  operation may help here.
+- Non-critical secure world service is not functioning correctly.
+- BL31 SPD discovers minor configuration problem with corresponding SP.
+
+Handling unrecoverable errors
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+In some cases it may not be possible for the secure world to recover from an
+error. This situation should be handled in one of the following ways:
+
+1. If the unrecoverable error is unexpected then emit an ``ERROR`` message and
+   call ``panic()``. This will end up calling the platform-specific function
+   ``plat_panic_handler()``.
+2. If the unrecoverable error is expected to occur in certain circumstances,
+   then emit an ``ERROR`` message and call the platform-specific function
+   ``plat_error_handler()``.
+
+Cases 1 and 2 are subtly different. A platform may implement
+``plat_panic_handler`` and ``plat_error_handler`` in the same way (for example,
+by waiting for a secure watchdog to time-out or by invoking an interface on the
+platform's power controller to reset the platform). However,
+``plat_error_handler`` may take additional action for some errors (for example,
+it may set a flag so the platform resets into a different mode). Also,
+``plat_panic_handler()`` may implement additional debug functionality (for
+example, invoking a hardware breakpoint).
+
+Examples of unexpected unrecoverable errors:
+
+- BL32 receives an unexpected SMC response from BL31 that it is unable to
+  recover from.
+- BL31 Trusted OS SPD code discovers that BL2 has not loaded the corresponding
+  Trusted OS, which is critical for platform operation.
+- Secure world discovers that a critical hardware device is an unexpected and
+  unrecoverable state.
+- Secure world receives an unexpected and unrecoverable error from a critical
+  hardware device.
+- Secure world discovers that it is running on unsupported hardware.
+
+Examples of expected unrecoverable errors:
+
+- BL1/BL2 fails to load the next image due to missing/corrupt firmware on disk.
+- BL1/BL2 fails to authenticate the next image due to an invalid certificate.
+- Secure world continuously receives recoverable errors from a hardware device
+  but is unable to proceed without a valid response.
+
+Handling critical unresponsiveness
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+If the secure world is waiting for a response from an external source (for
+example, the normal world or a hardware device) which is critical for continued
+operation, it must not wait indefinitely. It must have a mechanism (for example,
+a secure watchdog) for resetting itself and/or the external source to prevent
+the system from executing in this state indefinitely.
+
+Examples:
+
+- BL1 is waiting for the normal world to raise an SMC to proceed to the next
+  stage of the secure firmware update process.
+- A Trusted OS is waiting for a response from a proxy in the normal world that
+  is critical for continued operation.
+- Secure world is waiting for a hardware response that is critical for continued
+  operation.
+
+Use of built-in *C* and *libc* data types
+-----------------------------------------
+
+The |TF-A| codebase should be kept as portable as possible, especially since
+both 64-bit and 32-bit platforms are supported. To help with this, the following
+data type usage guidelines should be followed:
+
+- Where possible, use the built-in *C* data types for variable storage (for
+  example, ``char``, ``int``, ``long long``, etc) instead of the standard *C99*
+  types. Most code is typically only concerned with the minimum size of the
+  data stored, which the built-in *C* types guarantee.
+
+- Avoid using the exact-size standard *C99* types in general (for example,
+  ``uint16_t``, ``uint32_t``, ``uint64_t``, etc) since they can prevent the
+  compiler from making optimizations. There are legitimate uses for them,
+  for example to represent data of a known structure. When using them in struct
+  definitions, consider how padding in the struct will work across architectures.
+  For example, extra padding may be introduced in |AArch32| systems if a struct
+  member crosses a 32-bit boundary.
+
+- Use ``int`` as the default integer type - it's likely to be the fastest on all
+  systems. Also this can be assumed to be 32-bit as a consequence of the
+  `Procedure Call Standard for the Arm Architecture`_ and the `Procedure Call
+  Standard for the Arm 64-bit Architecture`_ .
+
+- Avoid use of ``short`` as this may end up being slower than ``int`` in some
+  systems. If a variable must be exactly 16-bit, use ``int16_t`` or
+  ``uint16_t``.
+
+- Avoid use of ``long``. This is guaranteed to be at least 32-bit but, given
+  that `int` is 32-bit on Arm platforms, there is no use for it. For integers of
+  at least 64-bit, use ``long long``.
+
+- Use ``char`` for storing text. Use ``uint8_t`` for storing other 8-bit data.
+
+- Use ``unsigned`` for integers that can never be negative (counts,
+  indices, sizes, etc). TF intends to comply with MISRA "essential type" coding
+  rules (10.X), where signed and unsigned types are considered different
+  essential types. Choosing the correct type will aid this. MISRA static
+  analysers will pick up any implicit signed/unsigned conversions that may lead
+  to unexpected behaviour.
+
+- For pointer types:
+
+  - If an argument in a function declaration is pointing to a known type then
+    simply use a pointer to that type (for example: ``struct my_struct *``).
+
+  - If a variable (including an argument in a function declaration) is pointing
+    to a general, memory-mapped address, an array of pointers or another
+    structure that is likely to require pointer arithmetic then use
+    ``uintptr_t``. This will reduce the amount of casting required in the code.
+    Avoid using ``unsigned long`` or ``unsigned long long`` for this purpose; it
+    may work but is less portable.
+
+  - For other pointer arguments in a function declaration, use ``void *``. This
+    includes pointers to types that are abstracted away from the known API and
+    pointers to arbitrary data. This allows the calling function to pass a
+    pointer argument to the function without any explicit casting (the cast to
+    ``void *`` is implicit). The function implementation can then do the
+    appropriate casting to a specific type.
+
+  - Avoid pointer arithmetic generally (as this violates MISRA C 2012 rule
+    18.4) and especially on void pointers (as this is only supported via
+    language extensions and is considered non-standard). In TF-A, setting the
+    ``W`` build flag to ``W=3`` enables the *-Wpointer-arith* compiler flag and
+    this will emit warnings where pointer arithmetic is used.
+
+  - Use ``ptrdiff_t`` to compare the difference between 2 pointers.
+
+- Use ``size_t`` when storing the ``sizeof()`` something.
+
+- Use ``ssize_t`` when returning the ``sizeof()`` something from a function that
+  can also return an error code; the signed type allows for a negative return
+  code in case of error. This practice should be used sparingly.
+
+- Use ``u_register_t`` when it's important to store the contents of a register
+  in its native size (32-bit in |AArch32| and 64-bit in |AArch64|). This is not a
+  standard *C99* type but is widely available in libc implementations,
+  including the FreeBSD version included with the TF codebase. Where possible,
+  cast the variable to a more appropriate type before interpreting the data. For
+  example, the following struct in ``ep_info.h`` could use this type to minimize
+  the storage required for the set of registers:
+
+.. code:: c
+
+    typedef struct aapcs64_params {
+            u_register_t arg0;
+            u_register_t arg1;
+            u_register_t arg2;
+            u_register_t arg3;
+            u_register_t arg4;
+            u_register_t arg5;
+            u_register_t arg6;
+            u_register_t arg7;
+    } aapcs64_params_t;
+
+If some code wants to operate on ``arg0`` and knows that it represents a 32-bit
+unsigned integer on all systems, cast it to ``unsigned int``.
+
+These guidelines should be updated if additional types are needed.
+
+Favor C language over assembly language
+---------------------------------------
+
+Generally, prefer code written in C over assembly. Assembly code is less
+portable, harder to understand, maintain and audit security wise. Also, static
+analysis tools generally don't analyze assembly code.
+
+There are, however, legitimate uses of assembly language. These include:
+
+  - Early boot code executed before the C runtime environment is setup.
+
+  - Exception handling code.
+
+  - Low-level code where the exact sequence of instructions executed on the CPU
+    matters, such as CPU reset sequences.
+
+  - Low-level code where specific system-level instructions must be used, such
+    as cache maintenance operations.

+Coding Style
+============
+
+The following sections outline the |TF-A| coding style for *C* code. The style
+is based on the `Linux kernel coding style`_, with a few modifications.
+
+The style should not be considered *set in stone*. Feel free to provide feedback
+and suggestions.
+
+.. note::
+   You will almost certainly find code in the |TF-A| repository that does not
+   follow the style. The intent is for all code to do so eventually.
+
+File Encoding
+-------------
+
+The source code must use the **UTF-8** character encoding. Comments and
+documentation may use non-ASCII characters when required (e.g. Greek letters
+used for units) but code itself is still limited to ASCII characters.
+
+Newlines must be in **Unix** style, which means that only the Line Feed (``LF``)
+character is used to break a line and reset to the first column.
+
+Language
+--------
+
+The primary language for comments and naming must be International English. In
+cases where there is a conflict between the American English and British English
+spellings of a word, the American English spelling is used.
+
+Exceptions are made when referring directly to something that does not use
+international style, such as the name of a company. In these cases the existing
+name should be used as-is.
+
+C Language Standard
+-------------------
+
+The C language mode used for TF-A is *GNU99*. This is the "GNU dialect of ISO
+C99", which implies the *ISO C99* standard with GNU extensions.
+
+Both GCC and Clang compiler toolchains have support for *GNU99* mode, though
+Clang does lack support for a small number of GNU extensions. These
+missing extensions are rarely used, however, and should not pose a problem.
+
+.. _misra-compliance:
+
+MISRA Compliance
+----------------
+
+TF-A attempts to comply with the `MISRA C:2012 Guidelines`_. Coverity
+Static Analysis is used to regularly generate a report of current MISRA defects
+and to prevent the addition of new ones.
+
+It is not possible for the project to follow all MISRA guidelines. We maintain
+`a spreadsheet`_ that lists all rules and directives and whether we aim to
+comply with them or not. A rationale is given for each deviation.
+
+.. note::
+   Enforcing a rule does not mean that the codebase is free of defects
+   of that rule, only that they would ideally be removed.
+
+.. note::
+   Third-party libraries are not considered in our MISRA analysis and we do not
+   intend to modify them to make them MISRA compliant.
+
+Indentation
+-----------
+
+Use **tabs** for indentation. The use of spaces for indentation is forbidden
+except in the case where a term is being indented to a boundary that cannot be
+achieved using tabs alone.
+
+Tab spacing should be set to **8 characters**.
+
+Trailing whitespace is not allowed and must be trimmed.
+
+Spacing
+-------
+
+Single spacing should be used around most operators, including:
+
+- Arithmetic operators (``+``, ``-``, ``/``, ``*``)
+- Assignment operators (``=``, ``+=``, etc)
+- Boolean operators (``&&``, ``||``)
+- Comparison operators (``<``, ``>``, ``==``, etc)
+
+A space should also be used to separate parentheses and braces when they are not
+already separated by a newline, such as for the ``if`` statement in the
+following example:
+
+.. code:: c
+
+  int function_foo(bool bar)
+  {
+      if (bar) {
+          function_baz();
+      }
+  }
+
+Note that there is no space between the name of a function and the following
+parentheses.
+
+Control statements (``if``, ``for``, ``switch``, ``while``, etc) must be
+separated from the following open parenthesis by a single space. The previous
+example illustrates this for an ``if`` statement.
+
+Line Length
+-----------
+
+Line length *should* be at most **80 characters**. This limit does not include
+non-printing characters such as the line feed.
+
+This rule is a *should*, not a must, and it is acceptable to exceed the limit
+**slightly** where the readability of the code would otherwise be significantly
+reduced. Use your judgement in these cases.
+
+Blank Lines
+-----------
+
+Functions are usually separated by a single blank line. In certain cases it is
+acceptable to use additional blank lines for clarity, if required.
+
+The file must end with a single newline character. Many editors have the option
+to insert this automatically and to trim multiple blank lines at the end of the
+file.
+
+Braces
+------
+
+Opening Brace Placement
+^^^^^^^^^^^^^^^^^^^^^^^
+
+Braces follow the **Kernighan and Ritchie (K&R)** style, where the opening brace
+is **not** placed on a new line.
+
+Example for a ``while`` loop:
+
+.. code:: c
+
+  while (condition) {
+      foo();
+      bar();
+  }
+
+This style applies to all blocks except for functions which, following the Linux
+style, **do** place the opening brace on a new line.
+
+Example for a function:
+
+.. code:: c
+
+  int my_function(void)
+  {
+      int a;
+
+      a = 1;
+      return a;
+  }
+
+Conditional Statement Bodies
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Where conditional statements (such as ``if``, ``for``, ``while`` and ``do``) are
+used, braces must be placed around the statements that form the body of the
+conditional. This is the case regardless of the number of statements in the
+body.
+
+.. note::
+  This is a notable departure from the Linux coding style that has been
+  adopted to follow MISRA guidelines more closely and to help prevent errors.
+
+For example, use the following style:
+
+.. code:: c
+
+  if (condition) {
+      foo++;
+  }
+
+instead of omitting the optional braces around a single statement:
+
+.. code:: c
+
+  /* This is violating MISRA C 2012: Rule 15.6 */
+  if (condition)
+      foo++;
+
+The reason for this is to prevent accidental changes to control flow when
+modifying the body of the conditional. For example, at a quick glance it is easy
+to think that the value of ``bar`` is only incremented if ``condition``
+evaluates to ``true`` but this is not the case - ``bar`` will always be
+incremented regardless of the condition evaluation. If the developer forgets to
+add braces around the conditional body when adding the ``bar++;`` statement then
+the program execution will not proceed as intended.
+
+.. code:: c
+
+  /* This is violating MISRA C 2012: Rule 15.6 */
+  if (condition)
+      foo++;
+      bar++;
+
+Naming
+------
+
+Functions
+^^^^^^^^^
+
+Use lowercase for function names, separating multiple words with an underscore
+character (``_``). This is sometimes referred to as *Snake Case*. An example is
+given below:
+
+.. code:: c
+
+  void bl2_arch_setup(void)
+  {
+      ...
+  }
+
+Local Variables and Parameters
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Local variables and function parameters use the same format as function names:
+lowercase with underscore separation between multiple words. An example is
+given below:
+
+.. code:: c
+
+  static void set_scr_el3_from_rm(uint32_t type,
+                                  uint32_t interrupt_type_flags,
+                                  uint32_t security_state)
+  {
+      uint32_t flag, bit_pos;
+
+      ...
+
+  }
+
+Preprocessor Macros
+^^^^^^^^^^^^^^^^^^^
+
+Identifiers that are defined using preprocessor macros are written in all
+uppercase text.
+
+.. code:: c
+
+  #define BUFFER_SIZE_BYTES 64
+
+Function Attributes
+-------------------
+
+Place any function attributes after the function type and before the function
+name.
+
+.. code:: c
+
+   void __init plat_arm_interconnect_init(void);
+
+Alignment
+---------
+
+Alignment should be performed primarily with tabs, adding spaces if required to
+achieve a granularity that is smaller than the tab size. For example, with a tab
+size of eight columns it would be necessary to use one tab character and two
+spaces to indent text by ten columns.
+
+Switch Statement Alignment
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+When using ``switch`` statements, align each ``case`` statement with the
+``switch`` so that they are in the same column.
+
+.. code:: c
+
+  switch (condition) {
+  case A:
+      foo();
+  case B:
+      bar();
+  default:
+      baz();
+  }
+
+Pointer Alignment
+^^^^^^^^^^^^^^^^^
+
+The reference and dereference operators (ampersand and *pointer star*) must be
+aligned with the name of the object on which they are operating, as opposed to
+the type of the object.
+
+.. code:: c
+
+  uint8_t *foo;
+
+  foo = &bar;
+
+
+Comments
+--------
+
+The general rule for comments is that the double-slash style of comment (``//``)
+is not allowed. Examples of the allowed comment formats are shown below:
+
+.. code:: c
+
+  /*
+   * This example illustrates the first allowed style for multi-line comments.
+   *
+   * Blank lines within multi-lines are allowed when they add clarity or when
+   * they separate multiple contexts.
+   *
+   */
+
+.. code:: c
+
+  /**************************************************************************
+   * This is the second allowed style for multi-line comments.
+   *
+   * In this style, the first and last lines use asterisks that run the full
+   * width of the comment at its widest point.
+   *
+   * This style can be used for additional emphasis.
+   *
+   *************************************************************************/
+
+.. code:: c
+
+  /* Single line comments can use this format */
+
+.. code:: c
+
+  /***************************************************************************
+   * This alternative single-line comment style can also be used for emphasis.
+   **************************************************************************/
+
+Headers and inclusion
+---------------------
+
+Header guards
+^^^^^^^^^^^^^
+
+For a header file called "some_driver.h" the style used by |TF-A| is:
+
+.. code:: c
+
+  #ifndef SOME_DRIVER_H
+  #define SOME_DRIVER_H
+
+  <header content>
+
+  #endif /* SOME_DRIVER_H */
+
+Include statement ordering
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+All header files that are included by a source file must use the following,
+grouped ordering. This is to improve readability (by making it easier to quickly
+read through the list of headers) and maintainability.
+
+#. *System* includes: Header files from the standard *C* library, such as
+   ``stddef.h`` and ``string.h``.
+
+#. *Project* includes: Header files under the ``include/`` directory within
+   |TF-A| are *project* includes.
+
+#. *Platform* includes: Header files relating to a single, specific platform,
+   and which are located under the ``plat/<platform_name>`` directory within
+   |TF-A|, are *platform* includes.
+
+Within each group, ``#include`` statements must be in alphabetical order,
+taking both the file and directory names into account.
+
+Groups must be separated by a single blank line for clarity.
+
+The example below illustrates the ordering rules using some contrived header
+file names; this type of name reuse should be otherwise avoided.
+
+.. code:: c
+
+  #include <string.h>
+
+  #include <a_dir/example/a_header.h>
+  #include <a_dir/example/b_header.h>
+  #include <a_dir/test/a_header.h>
+  #include <b_dir/example/a_header.h>
+
+  #include "a_header.h"
+
+Include statement variants
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Two variants of the ``#include`` directive are acceptable in the |TF-A|
+codebase. Correct use of the two styles improves readability by suggesting the
+location of the included header and reducing ambiguity in cases where generic
+and platform-specific headers share a name.
+
+For header files that are in the same directory as the source file that is
+including them, use the ``"..."`` variant.
+
+For header files that are **not** in the same directory as the source file that
+is including them, use the ``<...>`` variant.
+
+Example (bl1_fwu.c):
+
+.. code:: c
+
+  #include <assert.h>
+  #include <errno.h>
+  #include <string.h>
+
+  #include "bl1_private.h"
+
+Typedefs
+--------
+
+Avoid anonymous typedefs of structs/enums in headers
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+For example, the following definition:
+
+.. code:: c
+
+  typedef struct {
+          int arg1;
+          int arg2;
+  } my_struct_t;
+
+
+is better written as:
+
+.. code:: c
+
+  struct my_struct {
+          int arg1;
+          int arg2;
+  };
+
+This allows function declarations in other header files that depend on the
+struct/enum to forward declare the struct/enum instead of including the
+entire header:
+
+.. code:: c
+
+  struct my_struct;
+  void my_func(struct my_struct *arg);
+
+instead of:
+
+.. code:: c
+
+  #include <my_struct.h>
+  void my_func(my_struct_t *arg);
+
+Some TF definitions use both a struct/enum name **and** a typedef name. This
+is discouraged for new definitions as it makes it difficult for TF to comply
+with MISRA rule 8.3, which states that "All declarations of an object or
+function shall use the same names and type qualifiers".
+
+The Linux coding standards also discourage new typedefs and checkpatch emits
+a warning for this.
+
+Existing typedefs will be retained for compatibility.

+Commit Style
+============
+
+When writing commit messages, please think carefully about the purpose and scope
+of the change you are making: describe briefly what the change does, and
+describe in detail why it does it. This helps to ensure that changes to the
+code-base are transparent and approachable to reviewers, and it allows us to
+keep a more accurate changelog. You may use Markdown in commit messages.
+
+A good commit message provides all the background information needed for
+reviewers to understand the intent and rationale of the patch. This information
+is also useful for future reference.
+
+For example:
+
+- What does the patch do?
+- What motivated it?
+- What impact does it have?
+- How was it tested?
+- Have alternatives been considered? Why did you choose this approach over
+  another one?
+- If it fixes an `issue`_, include a reference.
+
+|TF-A| follows the `Conventional Commits`_ specification. All commits to the
+main repository are expected to adhere to these guidelines, so it is
+**strongly** recommended that you read at least the `quick summary`_ of the
+specification.
+
+To briefly summarize, commit messages are expected to be of the form:
+
+.. code::
+
+    <type>[optional scope]: <description>
+
+    [optional body]
+
+    [optional footer(s)]
+
+The following example commit message demonstrates the use of the
+``refactor`` type and the ``amu`` scope:
+
+.. code::
+
+    refactor(amu): factor out register accesses
+
+    This change introduces a small set of register getters and setters to
+    avoid having to repeatedly mask and shift in complex code.

++--------------+---------------------------------------------------------------+
+
+The permissible `scopes` are more flexible, and we maintain a list of them in
+our :download:`changelog configuration file <../../changelog.yaml>`. Scopes in
+this file are organized by their changelog section, where each changelog section
+has a single scope that is considered to be blessed, and possibly several
+deprecated scopes. Please avoid using deprecated scopes.
+
+While we don't enforce scopes strictly, we do ask that commits use these if they
+can, or add their own if no appropriate one exists (see :ref:`Adding Scopes`).
+
+It's highly recommended that you use the tooling installed by the optional steps
+in the :ref:`prerequisites <Prerequisites>` guide to validate commit messages
+locally, as commitlint reports a live list of the acceptable scopes.
+
+.. _Adding Scopes:
+
+Adding Scopes
+-------------
+
+Scopes that are not present in the changelog configuration file are considered
+to be deprecated, and should be avoided. If you are adding a new component that
+does not yet have a designated scope, please add one.
+
+For example, if you are adding or making modifications to `Foo`'s latest and
+greatest new platform `Bar` then you would add it to the `Platforms` changelog
+sub-section, and the hierarchy should look something like this:
+
+.. code:: yaml
+
+    - title: Platforms
+
+      subsections:
+        - title: Foo
+          scope: foo
+
+          subsections:
+            - title: Bar
+              scope: bar
+
+When creating new scopes, try to keep them short and succinct, and use kebab
+case (``this-is-kebab-case``). Components with a product name (i.e. most
+platforms and some drivers) should use that name (e.g. ``gic600ae``,
+``flexspi``, ``stpmic1``), otherwise use a name that uniquely represents the
+component (e.g. ``marvell-comphy-3700``, ``rcar3-drivers``, ``a3720-uart``).
+
+Mandated Trailers
+-----------------
+
+Commits are expected to be signed off with the ``Signed-off-by:`` trailer using
+your real name and email address. You can do this automatically by committing
+with Git's ``-s`` flag. By adding this line the contributor certifies the
+contribution is made under the terms of the :download:`Developer Certificate of
+Origin <../../dco.txt>`.
+
+There may be multiple ``Signed-off-by:`` lines depending on the history of the
+patch, but one **must** be the committer. More details may be found in the
+`Gerrit Signed-off-by Lines guidelines`_.
+
+Ensure that each commit also has a unique ``Change-Id:`` line. If you have
+followed optional steps in the prerequisites to either install the Node.js tools
+or clone the repository using the "`Clone with commit-msg hook`" clone method,
+then this should be done automatically for you.
+
+More details may be found in the `Gerrit Change-Ids documentation`_.

+Contributor's Guide
+*******************
+
+Getting Started
+===============
+
+-  Make sure you have a Github account and you are logged on both
+   `developer.trustedfirmware.org`_ and `review.trustedfirmware.org`_.
+
+-  If you plan to contribute a major piece of work, it is usually a good idea to
+   start a discussion around it on the mailing list. This gives everyone
+   visibility of what is coming up, you might learn that somebody else is
+   already working on something similar or the community might be able to
+   provide some early input to help shaping the design of the feature.
+
+   If you intend to include Third Party IP in your contribution, please mention
+   it explicitly in the email thread and ensure that the changes that include
+   Third Party IP are made in a separate patch (or patch series).
+
+-  Clone `Trusted Firmware-A`_ on your own machine as described in
+   :ref:`prerequisites_get_source`.
+
+-  Create a local topic branch based on the `Trusted Firmware-A`_ ``master``
+   branch.
+
+Making Changes
+==============
+
+-  Ensure commits adhere to the the project's :ref:`Commit Style`.
+
+-  Make commits of logical units. See these general `Git guidelines`_ for
+   contributing to a project.
+
+-  Keep the commits on topic. If you need to fix another bug or make another
+   enhancement, please address it on a separate topic branch.
+
+-  Split the patch in manageable units. Small patches are usually easier to
+   review so this will speed up the review process.
+
+-  Avoid long commit series. If you do have a long series, consider whether
+   some commits should be squashed together or addressed in a separate topic.
+
+-  Follow the :ref:`Coding Style` and :ref:`Coding Guidelines`.
+
+   -  Use the checkpatch.pl script provided with the Linux source tree. A
+      Makefile target is provided for convenience, see :ref:`this
+      section<automatic-compliance-checking>` for more details.
+
+-  Where appropriate, please update the documentation.
+
+   -  Consider whether the :ref:`Porting Guide`, :ref:`Firmware Design` document
+      or other in-source documentation needs updating.
+
+   -  If you are submitting new files that you intend to be the code owner for
+      (for example, a new platform port), then also update the
+      :ref:`code owners` file.
+
+   -  For topics with multiple commits, you should make all documentation changes
+      (and nothing else) in the last commit of the series. Otherwise, include
+      the documentation changes within the single commit.
+
+.. _copyright-license-guidance:
+
+-  Ensure that each changed file has the correct copyright and license
+   information. Files that entirely consist of contributions to this project
+   should have a copyright notice and BSD-3-Clause SPDX license identifier of
+   the form as shown in :ref:`license`. Files that contain changes to imported
+   Third Party IP files should retain their original copyright and license
+   notices.
+
+   For significant contributions you may add your own copyright notice in the
+   following format:
+
+   ::
+
+       Portions copyright (c) [XXXX-]YYYY, <OWNER>. All rights reserved.
+
+   where XXXX is the year of first contribution (if different to YYYY) and YYYY
+   is the year of most recent contribution. <OWNER> is your name or your company
+   name.
+
+-  Ensure that each patch in the patch series compiles in all supported
+   configurations. Patches which do not compile will not be merged.
+
+-  Please test your changes. As a minimum, ensure that Linux boots on the
+   Foundation FVP. See :ref:`Arm Fixed Virtual Platforms (FVP)` for more
+   information. For more extensive testing, consider running the `TF-A Tests`_
+   against your patches.
+
+-  Ensure that all CI automated tests pass. Failures should be fixed. They might
+   block a patch, depending on how critical they are.
+
+Submitting Changes
+==================
+
+-  Submit your changes for review at https://review.trustedfirmware.org
+   targeting the ``integration`` branch.
+
+-  Add reviewers for your patch:
+
+   -  At least one code owner for each module modified by the patch. See the list
+      of modules and their :ref:`code owners`.
+
+   -  At least one maintainer. See the list of :ref:`maintainers`.
+
+   -  If some module has no code owner, try to identify a suitable (non-code
+      owner) reviewer. Running ``git blame`` on the module's source code can
+      help, as it shows who has been working the most recently on this area of
+      the code.
+
+      Alternatively, if it is impractical to identify such a reviewer, you might
+      send an email to the `TF-A mailing list`_ to broadcast your review request
+      to the community.
+
+   Note that self-reviewing a patch is prohibited, even if the patch author is
+   the only code owner of a module modified by the patch. Getting a second pair
+   of eyes on the code is essential to keep up with the quality standards the
+   project aspires to.
+
+-  The changes will then undergo further review by the designated people. Any
+   review comments will be made directly on your patch. This may require you to
+   do some rework. For controversial changes, the discussion might be moved to
+   the `TF-A mailing list`_ to involve more of the community.
+
+   Refer to the `Gerrit Uploading Changes documentation`_ for more details.
+
+-  The patch submission rules are the following. For a patch to be approved
+   and merged in the tree, it must get:
+
+   -  One ``Code-Owner-Review+1`` for each of the modules modified by the patch.
+   -  A ``Maintainer-Review+1``.
+
+   In the case where a code owner could not be found for a given module,
+   ``Code-Owner-Review+1`` is substituted by ``Code-Review+1``.
+
+   In addition to these various code review labels, the patch must also get a
+   ``Verified+1``. This is usually set by the Continuous Integration (CI) bot
+   when all automated tests passed on the patch. Sometimes, some of these
+   automated tests may fail for reasons unrelated to the patch. In this case,
+   the maintainers might (after analysis of the failures) override the CI bot
+   score to certify that the patch has been correctly tested.
+
+   In the event where the CI system lacks proper tests for a patch, the patch
+   author or a reviewer might agree to perform additional manual tests
+   in their review and the reviewer incorporates the review of the additional
+   testing in the ``Code-Review+1`` or ``Code-Owner-Review+1`` as applicable to
+   attest that the patch works as expected. Where possible additional tests should
+   be added to the CI system as a follow up task. For example, for a
+   platform-dependent patch where the said platform is not available in the CI
+   system's board farm.
+
+-  When the changes are accepted, the :ref:`maintainers` will integrate them.
+
+   -  Typically, the :ref:`maintainers` will merge the changes into the
+      ``integration`` branch.
+
+   -  If the changes are not based on a sufficiently-recent commit, or if they
+      cannot be automatically rebased, then the :ref:`maintainers` may rebase it
+      on the ``integration`` branch or ask you to do so.
+
+   -  After final integration testing, the changes will make their way into the
+      ``master`` branch. If a problem is found during integration, the
+      :ref:`maintainers` will request your help to solve the issue. They may
+      revert your patches and ask you to resubmit a reworked version of them or
+      they may ask you to provide a fix-up patch.
+
+Add CI Configurations
+=====================
+
+-  TF-A uses Jenkins tool for Continuous Integration and testing activities.
+   Various CI Jobs are deployed which run tests on every patch before being
+   merged. So each of your patches go through a series of checks before they
+   get merged on to the master branch. Kindly ensure, that everytime you add
+   new files under your platform, they are covered under the following two sections:
+
+Coverity Scan
+-------------
+
+-  ``Coverity Scan analysis`` is one of the tests we perform on our source code
+   at regular intervals. We maintain a build script ``tf-cov-make`` which contains the
+   build configurations of various platforms in order to cover the entire source
+   code being analysed by Coverity.
+
+-  When you submit your patches for review containing new source files, please
+   ensure to include them for the ``Coverity Scan analysis`` by adding the
+   respective build configurations in the ``tf-cov-make`` build script.
+
+-  In this section you find the details on how to append your new build
+   configurations for Coverity scan analysis illustrated with examples:
+
+#. We maintain a separate repository named `tf-a-ci-scripts repository`_
+   for placing all the test scripts which will be executed by the CI Jobs.
+
+#. In this repository, ``tf-cov-make`` script is located at
+   ``tf-a-ci-scripts/script/tf-coverity/tf-cov-make``
+
+#. Edit `tf-cov-make`_ script by appending all the possible build configurations with
+   the specific ``build-flags`` relevant to your platform, so that newly added
+   source files get built and analysed by Coverity.
+
+#. For better understanding follow the below specified examples listed in the
+   ``tf-cov-make`` script.
+
+.. code:: shell
+
+    Example 1:
+    #Intel
+    make PLAT=stratix10 $(common_flags) all
+    make PLAT=agilex $(common_flags) all
+
+-  In the above example there are two different SoCs ``stratix`` and ``agilex``
+   under the Intel platform and the build configurations has been added suitably
+   to include most of their source files.
+
+.. code:: shell
+
+    Example 2:
+    #Hikey
+    make PLAT=hikey $(common_flags) ${TBB_OPTIONS} ENABLE_PMF=1 all
+    make PLAT=hikey960 $(common_flags) ${TBB_OPTIONS} all
+    make PLAT=poplar $(common_flags) all
+
+-  In this case for ``Hikey`` boards additional ``build-flags`` has been included
+   along with the ``commom_flags`` to cover most of the files relevant to it.
+
+-  Similar to this you can still find many other different build configurations
+   of various other platforms listed in the ``tf-cov-make`` script. Kindly refer
+   them and append your build configurations respectively.
+
+Test Build Configuration (``tf-l1-build-plat``)
+-----------------------------------------------
+
+-  Coverity Scan analysis, runs on a daily basis and will not be triggered for
+   every individual trusted-firmware patch.
+
+-  Considering this, we have other distinguished CI jobs which run a set of test
+   configurations on every patch, before they are being passed to ``Coverity scan analysis``.
+
+-  ``tf-l1-build-plat`` is the test group, which holds the test configurations
+   to build all the platforms. So be kind enough to verify that your newly added
+   files are built as part of one of the existing platform configurations present
+   in ``tf-l1-build-plat`` test group.
+
+-  In this section you find the details on how to add the appropriate files,
+   needed to build your newly introduced platform as part of ``tf-l1-build-plat``
+   test group, illustrated with an example:
+
+-  Lets consider ``Hikey`` platform:
+   In the `tf-a-ci-scripts repository`_ we need to add a build configuration file ``hikey-default``
+   under tf_config folder, ``tf_config/hikey-default`` listing all the build parameters
+   relevant to it.
+
+.. code:: shell
+
+   #Hikey Build Parameters
+   CROSS_COMPILE=aarch64-none-elf-
+   PLAT=hikey
+
+-  Further a test-configuration file ``hikey-default:nil`` need to be added under the
+   test group, ``tf-l1-build-plat`` located at ``tf-a-ci-scripts/group/tf-l1-build-plat``,
+   to allow the platform to be built as part of this group.
+
+.. code:: shell
+
+   #
+   # Copyright (c) 2019-2022 Arm Limited. All rights reserved.
+   #
+   # SPDX-License-Identifier: BSD-3-Clause
+   #
+
+-  As illustrated above, you need to add the similar files supporting your platform.
+
+Binary Components
+=================
+
+-  Platforms may depend on binary components submitted to the `Trusted Firmware
+   binary repository`_ if they require code that the contributor is unable or
+   unwilling to open-source. This should be used as a rare exception.
+-  All binary components must follow the contribution guidelines (in particular
+   licensing rules) outlined in the `readme.rst <tf-binaries-readme_>`_ file of
+   the binary repository.
+-  Binary components must be restricted to only the specific functionality that
+   cannot be open-sourced and must be linked into a larger open-source platform
+   port. The majority of the platform port must still be implemented in open
+   source. Platform ports that are merely a thin wrapper around a binary
+   component that contains all the actual code will not be accepted.
+-  Only platform port code (i.e. in the ``plat/<vendor>`` directory) may rely on
+   binary components. Generic code must always be fully open-source.

+Frequently-Asked Questions (FAQ)
+================================
+
+How do I update my changes?
+---------------------------
+
+Often it is necessary to update your patch set before it is merged. Refer to the
+`Gerrit Upload Patch Set documentation`_ on how to do so.
+
+If you need to modify an existing patch set with multiple commits, refer to the
+`Gerrit Replace Changes documentation`_.
+
+How long will my changes take to merge into ``integration``?
+------------------------------------------------------------
+
+This can vary a lot, depending on:
+
+* How important the patch set is considered by the TF maintainers. Where
+  possible, you should indicate the required timescales for merging the patch
+  set and the impact of any delay. Feel free to add a comment to your patch set
+  to get an estimate of when it will be merged.
+
+* The quality of the patch set. Patches are likely to be merged more quickly if
+  they follow the coding guidelines, have already had some code review, and have
+  been appropriately tested.
+
+* The impact of the patch set. For example, a patch that changes a key generic
+  API is likely to receive much greater scrutiny than a local change to a
+  specific platform port.
+
+* How much opportunity for external review is required. For example, the TF
+  maintainers may not wait for external review comments to merge trivial
+  bug-fixes but may wait up to a week to merge major changes, or ones requiring
+  feedback from specific parties.
+
+* How many other patch sets are waiting to be integrated and the risk of
+  conflict between the topics.
+
+* If there is a code freeze in place in preparation for the release. Please
+  refer the :ref:`Release Processes` document for more details.
+
+* The workload of the TF maintainers.
+
+How long will it take for my changes to go from ``integration`` to ``master``?
+------------------------------------------------------------------------------
+
+This depends on how many concurrent patches are being processed at the same
+time. In simple cases where all potential regressions have already been tested,
+the delay will be less than 1 day. If the TF maintainers are trying to merge
+several things over the course of a few days, it might take up to a week.
+Typically, it will be 1-2 days.
+
+The worst case is if the TF maintainers are trying to make a release while also
+receiving patches that will not be merged into the release. In this case, the
+patches will be merged onto ``integration``, which will temporarily diverge from
+the release branch. The ``integration`` branch will be rebased onto ``master``
+after the release, and then ``master`` will be fast-forwarded to ``integration``
+1-2 days later. This whole process could take up 4 weeks. Please refer to the
+:ref:`Release Processes` document for code freeze dates. The TF maintainers
+will inform the patch owner if this is going to happen.
+
+It is OK to create a patch based on commits that are only available in
+``integration`` or another patch set, rather than ``master``. There is a risk
+that the dependency commits will change (for example due to patch set rework or
+integration problems). If this happens, the dependent patch will need reworking.
+
+What are these strange comments in my changes?
+----------------------------------------------
+
+All the comments from ``ci-bot-user`` are associated with Continuous Integration
+infrastructure. The links published on the comment are not currently accessible,
+but would be after the CI has been transitioned to `trustedfirmware.org`_.

+Platform Ports Policy
+=====================
+
+This document clarifies a couple of policy points around platform ports
+management.
+
+Platform compatibility policy
+-----------------------------
+
+Platform compatibility is mainly affected by changes to Platform APIs (as
+documented in the :ref:`Porting Guide`), driver APIs (like the GICv3 drivers) or
+library interfaces (like xlat_table library). The project will try to maintain
+compatibility for upstream platforms. Due to evolving requirements and
+enhancements, there might be changes affecting platform compatibility which
+means the previous interface needs to be deprecated and a new interface
+introduced to replace it. In case the migration to the new interface is trivial,
+the contributor of the change is expected to make good effort to migrate the
+upstream platforms to the new interface.
+
+The deprecated interfaces are listed inside :ref:`Release Processes` as well as
+the release after which each one will be removed. When an interface is
+deprecated, the page must be updated to indicate the release after which the
+interface will be removed. This must be at least 1 full release cycle in future.
+For non-trivial interface changes, an email should be sent out to the `TF-A
+public mailing list`_ to notify platforms that they should migrate away from the
+deprecated interfaces. Platforms are expected to migrate before the removal of
+the deprecated interface.
+
+Platform deprecation policy
+---------------------------
+
+If a platform is no longer maintained, it is best to deprecate it to keep the
+projects' source tree clean and healthy. Deprecation can be a 1-stage or 2-stage
+process (up to the platform maintainers).
+
+ - *2-stage*: The platform's source code can be kept in the repository for a
+   cooling off period before deleting it (typically 2 release cycles). In this
+   case, we keep track ot the *Deprecated* version separately from the *Deleted*
+   version.
+
+ - *1-stage*: The platform's source code can be deleted straight away. In this
+   case, both versions are the same.
+
+The :ref:`Platform Ports` page provides a list of all deprecated/deleted
+platform ports (or soon to be) to this day.

+Secure Development Guidelines
+=============================
+
+This page contains guidance on what to check for additional security measures,
+including build options that can be modified to improve security or catch issues
+early in development.
+
+Security considerations
+-----------------------
+
+Part of the security of a platform is handling errors correctly, as described in
+the previous section. There are several other security considerations covered in
+this section.
+
+Do not leak secrets to the normal world
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The secure world **must not** leak secrets to the normal world, for example in
+response to an SMC.
+
+Handling Denial of Service attacks
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The secure world **should never** crash or become unusable due to receiving too
+many normal world requests (a *Denial of Service* or *DoS* attack). It should
+have a mechanism for throttling or ignoring normal world requests.
+
+Preventing Secure-world timing information leakage via PMU counters
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The Secure world needs to implement some defenses to prevent the Non-secure
+world from making it leak timing information. In general, higher privilege
+levels must defend from those below when the PMU is treated as an attack
+vector.
+
+Refer to the :ref:`Performance Monitoring Unit` guide for detailed information
+on the PMU registers.
+
+Timing leakage attacks from the Non-secure world
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Since the Non-secure world has access to the ``PMCR`` register, it can
+configure the PMU to increment counters at any exception level and in both
+Secure and Non-secure state. Thus, it attempts to leak timing information from
+the Secure world.
+
+Shown below is an example of such a configuration:
+
+-  ``PMEVTYPER0_EL0`` and ``PMCCFILTR_EL0``:
+
+   -  Set ``P`` to ``0``.
+   -  Set ``NSK`` to ``1``.
+   -  Set ``M`` to ``0``.
+   -  Set ``NSH`` to ``0``.
+   -  Set ``SH`` to ``1``.
+
+-  ``PMCNTENSET_EL0``:
+
+   -  Set ``P[0]`` to ``1``.
+   -  Set ``C`` to ``1``.
+
+-  ``PMCR_EL0``:
+
+   -  Set ``DP`` to ``0``.
+   -  Set ``E`` to ``1``.
+
+This configuration instructs ``PMEVCNTR0_EL0`` and ``PMCCNTR_EL0`` to increment
+at Secure EL1, Secure EL2 (if implemented) and EL3.
+
+Since the Non-secure world has fine-grained control over where (at which
+exception levels) it instructs counters to increment, obtaining event counts
+would allow it to carry out side-channel timing attacks against the Secure
+world. Examples include Spectre, Meltdown, as well as extracting secrets from
+cryptographic algorithms with data-dependent variations in their execution
+time.
+
+Secure world mitigation strategies
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The ``MDCR_EL3`` register allows EL3 to configure the PMU (among other things).
+The `Arm ARM`_ details all of the bit fields in this register, but for the PMU
+there are two bits which determine the permissions of the counters:
+
+-  ``SPME`` for the programmable counters.
+-  ``SCCD`` for the cycle counter.
+
+Depending on the implemented features, the Secure world can prohibit counting
+in AArch64 state via the following:
+
+-  ARMv8.2-Debug not implemented:
+
+   -  Prohibit general event counters and the cycle counter:
+      ``MDCR_EL3.SPME == 0 && PMCR_EL0.DP == 1 && !ExternalSecureNoninvasiveDebugEnabled()``.
+
+      -  ``MDCR_EL3.SPME`` resets to ``0``, so by default general events should
+         not be counted in the Secure world.
+      -  The ``PMCR_EL0.DP`` bit therefore needs to be set to ``1`` when EL3 is
+         entered and ``PMCR_EL0`` needs to be saved and restored in EL3.
+      -  ``ExternalSecureNoninvasiveDebugEnabled()`` is an authentication
+         interface which is implementation-defined unless ARMv8.4-Debug is
+         implemented. The `Arm ARM`_ has detailed information on this topic.
+
+   -  The only other way is to disable the ``PMCR_EL0.E`` bit upon entering
+      EL3, which disables counting altogether.
+
+-  ARMv8.2-Debug implemented:
+
+   -  Prohibit general event counters: ``MDCR_EL3.SPME == 0``.
+   -  Prohibit cycle counter: ``MDCR_EL3.SPME == 0 && PMCR_EL0.DP == 1``.
+      ``PMCR_EL0`` therefore needs to be saved and restored in EL3.
+
+-  ARMv8.5-PMU implemented:
+
+   -  Prohibit general event counters: as in ARMv8.2-Debug.
+   -  Prohibit cycle counter: ``MDCR_EL3.SCCD == 1``
+
+In Aarch32 execution state the ``MDCR_EL3`` alias is the ``SDCR`` register,
+which has some of the bit fields of ``MDCR_EL3``, most importantly the ``SPME``
+and ``SCCD`` bits.
+
+Build options
+-------------
+
+Several build options can be used to check for security issues. Refer to the
+:ref:`Build Options` for detailed information on these.
+
+- The ``BRANCH_PROTECTION`` build flag can be used to enable Pointer
+  Authentication and Branch Target Identification.
+
+- The ``ENABLE_STACK_PROTECTOR`` build flag can be used to identify buffer
+  overflows.
+
+- The ``W`` build flag can be used to enable a number of compiler warning
+  options to detect potentially incorrect code.
+
+  - W=0 (default value)
+
+    The ``Wunused`` with ``Wno-unused-parameter``, ``Wdisabled-optimization``
+    and ``Wvla`` flags are enabled.
+
+    The ``Wunused-but-set-variable``, ``Wmaybe-uninitialized`` and
+    ``Wpacked-bitfield-compat`` are GCC specific flags that are also enabled.
+
+  - W=1
+
+    Adds ``Wextra``, ``Wmissing-format-attribute``, ``Wmissing-prototypes``,
+    ``Wold-style-definition`` and ``Wunused-const-variable``.
+
+  - W=2
+
+    Adds ``Waggregate-return``, ``Wcast-align``, ``Wnested-externs``,
+    ``Wshadow``, ``Wlogical-op``.
+
+  - W=3
+
+    Adds ``Wbad-function-cast``, ``Wcast-qual``, ``Wconversion``, ``Wpacked``,
+    ``Wpointer-arith``, ``Wredundant-decls`` and
+    ``Wswitch-default``.
+
+  Refer to the GCC or Clang documentation for more information on the individual
+  options: https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html and
+  https://clang.llvm.org/docs/DiagnosticsReference.html.
+
+  NB: The ``Werror`` flag is enabled by default in TF-A and can be disabled by
+  setting the ``E`` build flag to 0.

+Security Handling
+=================
+
+Security Disclosures
+--------------------
+
+We disclose all security vulnerabilities we find, or are advised about, that are
+relevant to Trusted Firmware-A. We encourage responsible disclosure of
+vulnerabilities and inform users as best we can about all possible issues.
+
+We disclose TF-A vulnerabilities as Security Advisories, all of which are listed
+at the bottom of this page. Any new ones will, additionally, be announced as
+issues in the project's `issue tracker`_ with the ``security-advisory`` tag. You
+can receive notification emails for these by watching the "Trusted Firmware-A"
+project at https://developer.trustedfirmware.org/.
+
+Found a Security Issue?
+-----------------------
+
+Although we try to keep TF-A secure, we can only do so with the help of the
+community of developers and security researchers.
+
+.. warning::
+   If you think you have found a security vulnerability, please **do not**
+   report it in the `issue tracker`_ or on the `mailing list`_. Instead, please
+   follow the `TrustedFirmware.org security incident process`_.
+
+One of the goals of this process is to ensure providers of products that use
+TF-A have a chance to consider the implications of the vulnerability and its
+remedy before it is made public. As such, please follow the disclosure plan
+outlined in the process. We do our best to respond and fix any issues quickly.
+
+Afterwards, we encourage you to write-up your findings about the TF-A source
+code.
+
+Attribution
+-----------
+
+We will name and thank you in the :ref:`Change Log & Release Notes` distributed
+with the source code and in any published security advisory.

+
+Generic Trusted Firmware (TF) BL1 code contains an SMC interface that is briefly
+available after cold reset to support the Firmware Update (FWU) feature (also
+known as recovery mode). This allows most FWU functionality to be implemented in
+the normal world, while retaining the essential image authentication
+functionality in BL1. When cold boot reaches the EL3 Runtime Software (for
+example, BL31 on AArch64 systems), the FWU SMC interface is replaced by the EL3
+Runtime SMC interface. Platforms may choose how much of this FWU functionality
+to use, if any.
+
+The BL1 FWU SMC handling code, currently only supported on AArch64, contains
+several vulnerabilities that may be exploited when *all* the following
+conditions apply:
+
+1. Platform code uses TF BL1 with the ``TRUSTED_BOARD_BOOT`` build option
+   enabled.
+
+2. Platform code arranges for untrusted normal world FWU code to be executed in
+   the cold boot path, before BL31 starts. Untrusted in this sense means code
+   that is not in ROM or has not been authenticated or has otherwise been
+   executed by an attacker.
+
+3. Platform code copies the insecure pattern described below from the ARM
+   platform version of ``bl1_plat_mem_check()``.
+
+The vulnerabilities consist of potential integer overflows in the input
+validation checks while handling the ``FWU_SMC_IMAGE_COPY`` SMC. The SMC
+implementation is designed to copy an image into secure memory for subsequent
+authentication, but the vulnerabilities may allow an attacker to copy
+unexpectedly large data into secure memory. Note that a separate vulnerability
+is required to leverage these vulnerabilities; for example a way to get the
+system to change its behaviour based on the unexpected secure memory contents.
+
+Two of the vulnerabilities are in the function ``bl1_fwu_image_copy()`` in
+``bl1/bl1_fwu.c``. These are listed below, referring to the v1.3 tagged version
+of the code:
+
+- Line 155:
+
+  .. code:: c
+
+    /*
+     * If last block is more than expected then
+     * clip the block to the required image size.
+     */
+    if (image_desc->copied_size + block_size >
+         image_desc->image_info.image_size) {
+        block_size = image_desc->image_info.image_size -
+            image_desc->copied_size;
+        WARN("BL1-FWU: Copy argument block_size > remaining image size."
+            " Clipping block_size\n");
+    }
+
+    /* Make sure the image src/size is mapped. */
+    if (bl1_plat_mem_check(image_src, block_size, flags)) {
+        WARN("BL1-FWU: Copy arguments source/size not mapped\n");
+        return -ENOMEM;
+    }
+
+    INFO("BL1-FWU: Continuing image copy in blocks\n");
+
+    /* Copy image for given block size. */
+    base_addr += image_desc->copied_size;
+    image_desc->copied_size += block_size;
+    memcpy((void *)base_addr, (const void *)image_src, block_size);
+    ...
+
+  This code fragment is executed when the image copy operation is performed in
+  blocks over multiple SMCs. ``block_size`` is an SMC argument and therefore
+  potentially controllable by an attacker. A very large value may result in an
+  integer overflow in the 1st ``if`` statement, which would bypass the check,
+  allowing an unclipped ``block_size`` to be passed into
+  ``bl1_plat_mem_check()``. If ``bl1_plat_mem_check()`` also passes, this may
+  result in an unexpectedly large copy of data into secure memory.
+
+- Line 206:
+
+  .. code:: c
+
+    /* Make sure the image src/size is mapped. */
+    if (bl1_plat_mem_check(image_src, block_size, flags)) {
+        WARN("BL1-FWU: Copy arguments source/size not mapped\n");
+        return -ENOMEM;
+    }
+
+    /* Find out how much free trusted ram remains after BL1 load */
+    mem_layout = bl1_plat_sec_mem_layout();
+    if ((image_desc->image_info.image_base < mem_layout->free_base) ||
+         (image_desc->image_info.image_base + image_size >
+          mem_layout->free_base + mem_layout->free_size)) {
+        WARN("BL1-FWU: Memory not available to copy\n");
+        return -ENOMEM;
+    }
+
+    /* Update the image size. */
+    image_desc->image_info.image_size = image_size;
+
+    /* Copy image for given size. */
+    memcpy((void *)base_addr, (const void *)image_src, block_size);
+    ...
+
+  This code fragment is executed during the 1st invocation of the image copy
+  operation. Both ``block_size`` and ``image_size`` are SMC arguments. A very
+  large value of ``image_size`` may result in an integer overflow in the 2nd
+  ``if`` statement, which would bypass the check, allowing execution to proceed.
+  If ``bl1_plat_mem_check()`` also passes, this may result in an unexpectedly
+  large copy of data into secure memory.
+
+If the platform's implementation of ``bl1_plat_mem_check()`` is correct then it
+may help prevent the above 2 vulnerabilities from being exploited. However, the
+ARM platform version of this function contains a similar vulnerability:
+
+- Line 88 of ``plat/arm/common/arm_bl1_fwu.c`` in function of
+  ``bl1_plat_mem_check()``:
+
+  .. code:: c
+
+    while (mmap[index].mem_size) {
+        if ((mem_base >= mmap[index].mem_base) &&
+            ((mem_base + mem_size)
+            <= (mmap[index].mem_base +
+            mmap[index].mem_size)))
+            return 0;
+
+        index++;
+    }
+    ...
+
+  This function checks that the passed memory region is within one of the
+  regions mapped in by ARM platforms. Here, ``mem_size`` may be the
+  ``block_size`` passed from ``bl1_fwu_image_copy()``. A very large value of
+  ``mem_size`` may result in an integer overflow and the function to incorrectly
+  return success. Platforms that copy this insecure pattern will have the same
+  vulnerability.

+The ``MDCR_EL3.SDD`` bit controls AArch64 secure self-hosted invasive debug
+enablement. By default, the BL1 and BL31 images of the current version of ARM
+Trusted Firmware (TF) unconditionally assign this bit to ``0`` in the early
+entrypoint code, which enables debug exceptions from the secure world. This can
+be seen in the implementation of the ``el3_arch_init_common`` `AArch64 macro`_ .
+Given that TF does not currently contain support for this feature (for example,
+by saving and restoring the appropriate debug registers), this may allow a
+normal world attacker to induce a panic in the secure world.
+
+The ``MDCR_EL3.SDD`` bit should be assigned to ``1`` to disable debug exceptions
+from the secure world.
+
+Earlier versions of TF (prior to `commit 495f3d3`_) did not assign this bit.
+Since the bit has an architecturally ``UNKNOWN`` reset value, earlier versions
+may or may not have the same problem, depending on the platform.
+
+A similar issue applies to the ``MDCR_EL3.SPD32`` bits, which control AArch32
+secure self-hosted invasive debug enablement. TF assigns these bits to ``00``
+meaning that debug exceptions from Secure EL1 are enabled by the authentication
+interface. Therefore this issue only exists for AArch32 Secure EL1 code when
+secure privileged invasive debug is enabled by the authentication interface, at
+which point the device is vulnerable to other, more serious attacks anyway.
+
+However, given that TF contains no support for handling debug exceptions, the
+``MDCR_EL3.SPD32`` bits should be assigned to ``10`` to disable debug exceptions
+from AArch32 Secure EL1.
+
+Finally, this also issue applies to AArch32 platforms that use the TF SP_MIN
+image or integrate the `AArch32 equivalent`_ of the ``el3_arch_init_common``
+macro. Here the affected bits are ``SDCR.SPD``, which should also be assigned to
+``10`` instead of ``00``

+
+The translation table library in ARM Trusted Firmware (TF) (under
+``lib/xlat_tables`` and ``lib/xlat_tables_v2``) provides APIs to help program
+translation tables in the MMU. The xlat\_tables client specifies its required
+memory mappings in the form of ``mmap_region`` structures.  Each ``mmap_region``
+has memory attributes represented by the ``mmap_attr_t`` enumeration type. This
+contains flags to control data access permissions (``MT_RO``/``MT_RW``) and
+instruction execution permissions (``MT_EXECUTE``/``MT_EXECUTE_NEVER``). Thus a
+mapping specifying both ``MT_RO`` and ``MT_EXECUTE_NEVER`` should result in a
+Read-Only (RO), non-executable memory region.
+
+This feature does not work correctly for AArch64 images executing at Secure EL1.
+Any memory region mapped as RO will always be executable, regardless of whether
+the client specified ``MT_EXECUTE`` or ``MT_EXECUTE_NEVER``.
+
+The vulnerability is known to affect the BL2 and Test Secure Payload (TSP)
+images on platforms that enable the ``SEPARATE_CODE_AND_RODATA`` build option,
+which includes all ARM standard platforms, and the upstream Xilinx and NVidia
+platforms. The RO data section for these images on these platforms is
+unexpectedly executable instead of non-executable. Other platforms or
+``xlat_tables`` clients may also be affected.
+
+The vulnerability primarily manifests itself after `Pull Request #662`_.  Before
+that, ``xlat_tables`` clients could not specify instruction execution
+permissions separately to data access permissions. All RO normal memory regions
+were implicitly executable. Before `Pull Request #662`_.  the vulnerability
+would only manifest itself for device memory mapped as RO; use of this mapping
+is considered rare, although the upstream QEMU platform uses this mapping when
+the ``DEVICE2_BASE`` build option is used.
+
+Note that one or more separate vulnerabilities are also required to exploit this
+vulnerability.
+
+The vulnerability is due to incorrect handling of the execute-never bits in the
+translation tables. The EL3 translation regime uses a single ``XN`` bit to
+determine whether a region is executable. The Secure EL1&0 translation regime
+handles 2 Virtual Address (VA) ranges and so uses 2 bits, ``UXN`` and ``PXN``.
+The ``xlat_tables`` library only handles the ``XN`` bit, which maps to ``UXN``
+in the Secure EL1&0 regime. As a result, this programs the Secure EL0 execution
+permissions but always leaves the memory as executable at Secure EL1.
+
+The vulnerability is mitigated by the following factors:
+
+- The xlat\_tables library ensures that all Read-Write (RW) memory regions are
+  non-executable by setting the ``SCTLR_ELx.WXN`` bit. This overrides any value
+  of the ``XN``, ``UXN`` or ``PXN`` bits in the translation tables. See the
+  ``enable_mmu()`` function:
+
+  ::
+
+      sctlr = read_sctlr_el##_el();               \
+      sctlr |= SCTLR_WXN_BIT | SCTLR_M_BIT;       \
+
+- AArch32 configurations are unaffected. Here the ``XN`` bit controls execution
+  privileges of the currently executing translation regime, which is the desired
+  behaviour.
+
+- ARM TF EL3 code (for example BL1 and BL31) ensures that all non-secure memory
+  mapped into the secure world is non-executable by setting the ``SCR_EL3.SIF``
+  bit. See the ``el3_arch_init_common`` macro in ``el3_common_macros.S``.

+
+The ``include/lib/utils_def.h`` header file provides the
+``check_uptr_overflow()`` macro, which aims at detecting arithmetic overflows
+that may occur when computing the sum of a base pointer and an offset. This
+macro evaluates to 1 if the sum of the given base pointer and offset would
+result in a value large enough to wrap around, which may lead to unpredictable
+behaviour.
+
+The macro code is at line 52, referring to the version of the code as of `commit
+c396b73`_:
+
+.. code:: c
+
+    /*
+     * Evaluates to 1 if (ptr + inc) overflows, 0 otherwise.
+     * Both arguments must be unsigned pointer values (i.e. uintptr_t).
+     */
+    #define check_uptr_overflow(ptr, inc)       \
+        (((ptr) > UINTPTR_MAX - (inc)) ? 1 : 0)
+
+This macro does not work correctly for AArch32 images. It fails to detect
+overflows when the sum of its two parameters fall into the ``[2^32, 2^64 - 1]``
+range. Therefore, any AArch32 code relying on this macro to detect such integer
+overflows is actually not protected.
+
+The buggy code has been present in ARM Trusted Firmware (TF) since `Pull Request
+#678`_ was merged (on 18 August 2016). However, the upstream code was not
+vulnerable until `Pull Request #939`_ was merged (on 22 May 2017), which
+introduced AArch32 support for the Trusted Board Boot (TBB) feature. Before
+then, the ``check_uptr_overflow()`` macro was not used in AArch32 code.
+
+The vulnerability resides in the BL1 FWU SMC handling code and it may be
+exploited when *all* the following conditions apply:
+
+- Platform code uses TF BL1 with the ``TRUSTED_BOARD_BOOT`` build option.
+
+- Platform code uses the Firmware Update (FWU) code provided in
+  ``bl1/bl1_fwu.c``, which is part of the TBB support.
+
+- TF BL1 is compiled with the ``ARCH=aarch32`` build option.
+
+In this context, the AArch32 BL1 image might fail to detect potential integer
+overflows in the input validation checks while handling the
+``FWU_SMC_IMAGE_COPY`` and ``FWU_SMC_IMAGE_AUTH`` SMCs.
+
+The ``FWU_SMC_IMAGE_COPY`` SMC handler is designed to copy an image into secure
+memory for subsequent authentication. This is implemented by the
+``bl1_fwu_image_copy()`` function, which has the following function prototype:
+
+.. code:: c
+
+     static int bl1_fwu_image_copy(unsigned int image_id,
+                        uintptr_t image_src,
+                        unsigned int block_size,
+                        unsigned int image_size,
+                        unsigned int flags)
+
+``image_src`` is an SMC argument and therefore potentially controllable by an
+attacker. A very large 32-bit value, for example ``2^32 -1``, may result in the
+sum of ``image_src`` and ``block_size`` overflowing a 32-bit type, which
+``check_uptr_overflow()`` will fail to detect.  Depending on its implementation,
+the platform-specific function ``bl1_plat_mem_check()`` might get defeated by
+these unsanitized values and allow the following memory copy operation, that
+would wrap around.  This may allow an attacker to copy unexpected data into
+secure memory if the memory is mapped in BL1's address space, or cause a fatal
+exception if it's not.
+
+The ``FWU_SMC_IMAGE_AUTH`` SMC handler is designed to authenticate an image
+resident in secure memory. This is implemented by the ``bl1_fwu_image_auth()``
+function, which has the following function prototype:
+
+.. code:: c
+
+    static int bl1_fwu_image_auth(unsigned int image_id,
+                        uintptr_t image_src,
+                        unsigned int image_size,
+                        unsigned int flags)
+
+Similarly, if an attacker has control over the ``image_src`` or ``image_size``
+arguments through the SMC interface and injects high values whose sum overflows,
+they might defeat the ``bl1_plat_mem_check()`` function and make the
+authentication module read data outside of what's normally allowed by the
+platform code or crash the platform.
+
+Note that in both cases, a separate vulnerability is required to leverage this
+vulnerability; for example a way to get the system to change its behaviour based
+on the unexpected secure memory accesses.  Moreover, the normal world FWU code
+would need to be compromised in order to send a malformed FWU SMC that triggers
+an integer overflow.
+
+The vulnerability is known to affect all ARM standard platforms when enabling
+the ``TRUSTED_BOARD_BOOT`` and ``ARCH=aarch32`` build options.  Other platforms
+may also be affected if they fulfil the above conditions.

+
+The ``PMCR_EL0`` (Performance Monitors Control Register) provides details of the
+Performance Monitors implementation, including the number of counters
+implemented, and configures and controls the counters. If the ``PMCR_EL0.DP``
+bit is set to zero, the cycle counter (when enabled) counts during secure world
+execution, even when prohibited by the debug signals.
+
+Since TF-A does not save and restore ``PMCR_EL0`` when switching between the
+normal and secure worlds, normal world code can set ``PMCR_EL0.DP`` to zero to
+cause leakage of secure world timing information. This register should be added
+to the list of saved/restored registers both when entering EL3 and also
+transitioning to S-EL1.
+
+Furthermore, ``PMCR_EL0.DP`` has an architecturally ``UNKNOWN`` reset value.
+Since Arm TF does not initialize this register, it's possible that on at least
+some implementations, ``PMCR_EL0.DP`` is set to zero by default. This and other
+bits with an architecturally UNKNOWN reset value should be initialized to
+sensible default values in the secure context.
+
+The same issue exists for the equivalent AArch32 register, ``PMCR``, except that
+here ``PMCR_EL0.DP`` architecturally resets to zero.
+
+NOTE: The original pull request referenced above only fixed the issue for S-EL1
+whereas the EL3 was fixed in the later commits.

+Variant 1 (`CVE-2017-5753`_)
+----------------------------
+
+At the time of writing, no vulnerable patterns have been observed in upstream TF
+code, therefore no workarounds have been applied or are planned.
+
+Variant 2 (`CVE-2017-5715`_)
+----------------------------
+
+Where possible on vulnerable CPUs, Arm recommends invalidating the branch
+predictor as early as possible on entry into the secure world, before any branch
+instruction is executed. There are a number of implementation defined ways to
+achieve this.
+
+For Cortex-A57 and Cortex-A72 CPUs, the Pull Requests (PRs) in this advisory
+invalidate the branch predictor when entering EL3 by disabling and re-enabling
+the MMU.
+
+For Cortex-A73 and Cortex-A75 CPUs, the PRs in this advisory invalidate the
+branch predictor when entering EL3 by temporarily dropping into AArch32
+Secure-EL1 and executing the ``BPIALL`` instruction. This workaround is
+significantly more complex than the "MMU disable/enable" workaround. The latter
+is not effective at invalidating the branch predictor on Cortex-A73/Cortex-A75.
+
+Note that if other privileged software, for example a Rich OS kernel, implements
+its own branch predictor invalidation during context switch by issuing an SMC
+(to execute firmware branch predictor invalidation), then there is a dependency
+on the PRs in this advisory being deployed in order for those workarounds to
+work. If that other privileged software is able to workaround the vulnerability
+locally (for example by implementing "MMU disable/enable" itself), there is no
+such dependency.
+
+`Pull Request #1240`_ and `Pull Request #1405`_ optimise the earlier fixes by
+implementing a specified `CVE-2017-5715`_ workaround SMC
+(``SMCCC_ARCH_WORKAROUND_1``) for use by normal world privileged software. This
+is more efficient than calling an arbitrary SMC (for example ``PSCI_VERSION``).
+Details of ``SMCCC_ARCH_WORKAROUND_1`` can be found in the `CVE-2017-5715
+mitigation specification`_.  The specification and implementation also enable
+the normal world to discover the presence of this firmware service.
+
+On Juno R1 we measured the round trip latency for both the ``PSCI_VERSION`` and
+``SMCCC_ARCH_WORKAROUND_1`` SMCs on Cortex-A57, using both the "MMU
+disable/enable" and "BPIALL at AArch32 Secure-EL1" workarounds described above.
+This includes the time spent in test code conforming to the SMC Calling
+Convention (SMCCC) from AArch64. For the ``SMCCC_ARCH_WORKAROUND_1`` cases, the
+test code uses SMCCC v1.1, which reduces the number of general purpose registers
+it needs to save/restore. Although the ``BPIALL`` instruction is not effective
+at invalidating the branch predictor on Cortex-A57, the drop into Secure-EL1
+with MMU disabled that this workaround entails effectively does invalidate the
+branch predictor. Hence this is a reasonable comparison.
+
+The results were as follows:
+
++------------------------------------------------------------------+-----------+
+| Test                                                             | Time (ns) |
++==================================================================+===========+
+| ``PSCI_VERSION`` baseline (without PRs in this advisory)         | 515       |
++------------------------------------------------------------------+-----------+
+| ``PSCI_VERSION`` baseline (with PRs in this advisory)            | 527       |
++------------------------------------------------------------------+-----------+
+| ``PSCI_VERSION`` with "MMU disable/enable"                       | 930       |
++------------------------------------------------------------------+-----------+
+| ``SMCCC_ARCH_WORKAROUND_1`` with "MMU disable/enable"            | 386       |
++------------------------------------------------------------------+-----------+
+| ``PSCI_VERSION`` with "BPIALL at AArch32 Secure-EL1"             | 1276      |
++------------------------------------------------------------------+-----------+
+| ``SMCCC_ARCH_WORKAROUND_1`` with "BPIALL at AArch32 Secure-EL1"  | 770       |
++------------------------------------------------------------------+-----------+
+
+Due to the high severity and wide applicability of this issue, the above
+workarounds are enabled by default (on vulnerable CPUs only), despite some
+performance and code size overhead. Platforms can choose to disable them at
+compile time if they do not require them. `Pull Request #1240`_ disables the
+workarounds for unaffected upstream platforms.
+
+For vulnerable AArch32-only CPUs (for example Cortex-A8, Cortex-A9 and
+Cortex-A17), the ``BPIALL`` instruction should be used as early as possible on
+entry into the secure world. For Cortex-A8, also set ``ACTLR[6]`` to 1 during
+early processor initialization. Note that the ``BPIALL`` instruction is not
+effective at invalidating the branch predictor on Cortex-A15. For that CPU, set
+``ACTLR[0]`` to 1 during early processor initialization, and invalidate the
+branch predictor by performing an ``ICIALLU`` instruction.
+
+On AArch32 EL3 systems, the monitor and secure-SVC code is typically tightly
+integrated, for example as part of a Trusted OS. Therefore any Variant 2
+workaround should be provided by vendors of that software and is outside the
+scope of TF. However, an example implementation in the minimal AArch32 Secure
+Payload, ``SP_MIN`` is provided in `Pull Request #1228`_.
+
+Other Arm CPUs are not vulnerable to this or other variants. This includes
+Cortex-A76, Cortex-A53, Cortex-A55, Cortex-A32, Cortex-A7 and Cortex-A5.
+
+For more information about non-Arm CPUs, please contact the CPU vendor.
+
+Variant 3 (`CVE-2017-5754`_)
+----------------------------
+
+This variant is only exploitable between Exception Levels within the same
+translation regime, for example between EL0 and EL1, therefore this variant
+cannot be used to access secure memory from the non-secure world, and is not
+applicable for TF. However, Secure Payloads (for example, Trusted OS) should
+provide mitigations on vulnerable CPUs to protect themselves from exploited
+Secure-EL0 applications.
+
+The only Arm CPU vulnerable to this variant is Cortex-A75.

+
+This security advisory describes the current understanding of the Trusted
+Firmware-A (TF-A) exposure to Variant 4 of the cache speculation vulnerabilities
+identified by `Google Project Zero`_.  To understand the background and wider
+impact of these vulnerabilities on Arm systems, please refer to the `Arm
+Processor Security Update`_.
+
+At the time of writing, the TF-A project is not aware of a Variant 4 exploit
+that could be used against TF-A. It is likely to be very difficult to achieve an
+exploit against current standard configurations of TF-A, due to the limited
+interfaces into the secure world with attacker-controlled inputs. However, this
+is becoming increasingly difficult to guarantee with the introduction of complex
+new firmware interfaces, for example the `Software Delegated Exception Interface
+(SDEI)`_.  Also, the TF-A project does not have visibility of all
+vendor-supplied interfaces. Therefore, the TF-A project takes a conservative
+approach by mitigating Variant 4 in hardware wherever possible during secure
+world execution. The mitigation is enabled by setting an implementation defined
+control bit to prevent the re-ordering of stores and loads.
+
+For each affected CPU type, TF-A implements one of the two following mitigation
+approaches in `Pull Request #1392`_ and `Pull Request #1397`_.  Both approaches
+have a system performance impact, which varies for each CPU type and use-case.
+The mitigation code is enabled by default, but can be disabled at compile time
+for platforms that are unaffected or where the risk is deemed low enough.
+
+Arm CPUs not mentioned below are unaffected.
+
+Static mitigation
+-----------------
+
+For affected CPUs, this approach enables the mitigation during EL3
+initialization, following every PE reset. No mechanism is provided to disable
+the mitigation at runtime.
+
+This approach permanently mitigates the entire software stack and no additional
+mitigation code is required in other software components.
+
+TF-A implements this approach for the following affected CPUs:
+
+- Cortex-A57 and Cortex-A72, by setting bit 55 (Disable load pass store) of
+  ``CPUACTLR_EL1`` (``S3_1_C15_C2_0``).
+
+- Cortex-A73, by setting bit 3 of ``S3_0_C15_C0_0`` (not documented in the
+  Technical Reference Manual (TRM)).
+
+- Cortex-A75, by setting bit 35 (reserved in TRM) of ``CPUACTLR_EL1``
+  (``S3_0_C15_C1_0``).
+
+Dynamic mitigation
+------------------
+
+For affected CPUs, this approach also enables the mitigation during EL3
+initialization, following every PE reset. In addition, this approach implements
+``SMCCC_ARCH_WORKAROUND_2`` in the Arm architectural range to allow callers at
+lower exception levels to temporarily disable the mitigation in their execution
+context, where the risk is deemed low enough. This approach enables mitigation
+on entry to EL3, and restores the mitigation state of the lower exception level
+on exit from EL3. For more information on this approach, see `Firmware
+interfaces for mitigating cache speculation vulnerabilities`_.
+
+This approach may be complemented by additional mitigation code in other
+software components, for example code that calls ``SMCCC_ARCH_WORKAROUND_2``.
+However, even without any mitigation code in other software components, this
+approach will effectively permanently mitigate the entire software stack, since
+the default mitigation state for firmware-managed execution contexts is enabled.
+
+Since the expectation in this approach is that more software executes with the
+mitigation disabled, this may result in better system performance than the
+static approach for some systems or use-cases.  However, for other systems or
+use-cases, this performance saving may be outweighed by the additional overhead
+of ``SMCCC_ARCH_WORKAROUND_2`` calls and TF-A exception handling.
+
+TF-A implements this approach for the following affected CPU:
+
+- Cortex-A76, by setting and clearing bit 16 (reserved in TRM) of
+  ``CPUACTLR2_EL1`` (``S3_0_C15_C1_1``).

++----------------+-------------------------------------------------------------+
+
+When taking an exception to EL3, BL31 saves the CPU context. The aim is to
+restore it before returning into the lower exception level software that called
+into the firmware. However, for an SMC exception, the general purpose registers
+``x0`` to ``x3`` are not part of the CPU context saved on the stack.
+
+As per the `SMC Calling Convention`_, up to 4 values may be returned to the
+caller in registers ``x0`` to ``x3``. In TF-A, these return values are written
+into the CPU context, typically using one of the ``SMC_RETx()`` macros provided
+in the ``include/lib/aarch64/smccc_helpers.h`` header file.
+
+Before returning to the caller, the ``restore_gp_registers()`` function is
+called. It restores the values of all general purpose registers taken from the
+CPU context stored on the stack. This includes registers ``x0`` to ``x3``, as
+can be seen in the ``lib/el3_runtime/aarch64/context.S`` file at line 339
+(referring to the version of the code as of `commit c385955`_):
+
+::
+
+    /*
+     * This function restores all general purpose registers except x30 from the
+     * CPU context. x30 register must be explicitly restored by the caller.
+     */
+    func restore_gp_registers
+        ldp x0, x1, [sp, #CTX_GPREGS_OFFSET + CTX_GPREG_X0]
+        ldp x2, x3, [sp, #CTX_GPREGS_OFFSET + CTX_GPREG_X2]
+
+In the case of an SMC handler that does not use all 4 return values, the
+remaining ones are left unchanged in the CPU context. As a result,
+``restore_gp_registers()`` restores the stale values saved by a previous SMC
+request (or asynchronous exception to EL3) that used these return values.
+
+In the presence of multiple normal world SMC clients, this behaviour might leak
+some of the return values from one client to another. For example, if a victim
+client first sends an SMC that returns 4 values, a malicious client may then
+send a second SMC expecting no return values (for example, a
+``SDEI_EVENT_COMPLETE`` SMC) to get the 4 return values of the victim client.
+
+In general, the responsibility for mitigating threats due to the presence of
+multiple normal world SMC clients lies with EL2 software.  When present, EL2
+software must trap SMC calls from EL1 software to ensure secure behaviour.
+
+For this reason, TF-A does not save ``x0`` to ``x3`` in the CPU context on an
+SMC synchronous exception. It has behaved this way since the first version.
+
+We can confirm that at least upstream KVM-based systems mitigate this threat,
+and are therefore unaffected by this issue. Other EL2 software should be audited
+to assess the impact of this threat.
+
+EL2 software might find mitigating this threat somewhat onerous, because for all
+SMCs it would need to be aware of which return registers contain valid data, so
+it can sanitise any unused return registers. On the other hand, mitigating this
+in EL3 is relatively easy and cheap. Therefore, TF-A will now ensure that no
+information is leaked through registers ``x0`` to ``x3``, by preserving the
+register state over the call.
+
+Note that AArch32 TF-A is not affected by this issue. The SMC handling code in
+``SP_MIN`` already saves all general purpose registers - including ``r0`` to
+``r3``, as can be seen in the ``include/lib/aarch32/smccc_macros.S`` file at
+line 19 (referring to the version of the code as of `commit c385955`_):
+
+.. code:: c
+
+    /*
+     * Macro to save the General purpose registers (r0 - r12), the banked
+     * spsr, lr, sp registers and the `scr` register to the SMC context on entry

+     * already saved. The `sp` must point to the `smc_ctx_t` to save to.
+     * Additionally, also save the 'pmcr' register as this is updated whilst
+     * executing in the secure world.

+To understand the background and wider impact of these vulnerabilities on Arm

+
+
+`CVE-2022-23960`_
+-----------------
+
+Where possible on vulnerable CPUs that implement FEAT_CSV2, Arm recommends
+inserting a loop workaround with implementation specific number of iterations
+that will discard the branch history on exception entry to a higher exception
+level for the given CPU. This is done as early as possible on entry into EL3,
+before any branch instruction is executed. This is sufficient to mitigate
+Spectre-BHB on behalf of all secure world code, assuming that no secure world
+code is under attacker control.
+
+The below table lists the CPUs that mitigate against this vulnerability in
+TF-A using the loop workaround(all cores that implement FEAT_CSV2 except the
+revisions of Cortex-A73 and Cortex-A75 that implements FEAT_CSV2).

+For all other cores impacted by Spectre-BHB, some of which that do not implement
+FEAT_CSV2 and some that do e.g. Cortex-A73, the recommended mitigation is to
+flush all branch predictions via an implementation specific route.
+
+In case local workaround is not feasible, the Rich OS can invoke the SMC
+(``SMCCC_ARCH_WORKAROUND_3``) to apply the workaround. Refer to `SMCCC Calling
+Convention specification`_ for more details.
+
+`Gerrit topic #spectre_bhb`_ This patchset implements the Spectre-BHB loop
+workaround for CPUs mentioned in the above table. For CPUs supporting
+speculative barrier instruction, the loop workaround is optimised by using SB
+in place of the common DSB and ISB sequence. It also mitigates against
+this vulnerability for Cortex-A72 CPU versions that support the CSV2 feature
+(from r1p0). The patch stack also includes an implementation for a specified
+`CVE-2022-23960`_ workaround SMC(``SMCCC_ARCH_WORKAROUND_3``) for use by normal
+world privileged software. Details of ``SMCCC_ARCH_WORKAROUND_3`` can be found
+in the `SMCCC Calling Convention specification`_. The specification and
+implementation also enables the normal world to discover the presence of this
+firmware service. This patch also implements ``SMCCC_ARCH_WORKAROUND_3`` for
+Cortex-A57, Coxtex-A72, Cortex-A73 and Cortex-A75 using the existing workaround.
+for CVE-2017-5715. Cortex-A15 patch extends Spectre V2 mitigation to Spectre-BHB.
+
+The above workaround is enabled by default (on vulnerable CPUs only). Platforms
+can choose to disable them at compile time if they do not require them.
+
+For more information about non-Arm CPUs, please contact the CPU vendor.

+Generic Threat Model
+********************
+
+************
+Introduction
+************
+
+This document provides a generic threat model for TF-A firmware.
+
+.. note::
+
+ This threat model doesn't consider Root and Realm worlds introduced by
+ :ref:`Realm Management Extension (RME)`.
+
+********************
+Target of Evaluation
+********************
+
+In this threat model, the target of evaluation is the Trusted
+Firmware for A-class Processors (TF-A). This includes the boot ROM (BL1),
+the trusted boot firmware (BL2) and the runtime EL3 firmware (BL31) as
+shown on Figure 1. Everything else on Figure 1 is outside of the scope of
+the evaluation.
+
+TF-A can be configured in various ways. In this threat model we consider
+only the most basic configuration. To that end we make the following
+assumptions:
+
+- All TF-A images are run from either ROM or on-chip trusted SRAM. This means
+  TF-A is not vulnerable to an attacker that can probe or tamper with off-chip
+  memory.
+
+- Trusted boot is enabled. This means an attacker can't boot arbitrary images
+  that are not approved by platform providers.
+
+- There is no Secure-EL2. We don't consider threats that may come with
+  Secure-EL2 software.
+
+- Measured boot is disabled. We do not consider the threats nor the mitigations
+  that may come with it.
+
+- No experimental features are enabled. We do not consider threats that may come
+  from them.
+
+Data Flow Diagram
+=================
+
+Figure 1 shows a high-level data flow diagram for TF-A. The diagram
+shows a model of the different components of a TF-A-based system and
+their interactions with TF-A. A description of each diagram element
+is given on Table 1. On the diagram, the red broken lines indicate
+trust boundaries. Components outside of the broken lines
+are considered untrusted by TF-A.

+  |                 |   other secure and non-secure images.                  |

+***************
+Threat Analysis
+***************
+
+In this section we identify and provide assessment of potential threats to TF-A
+firmware. The threats are identified for each diagram element on the
+data flow diagram above.
+
+For each threat, we identify the *asset* that is under threat, the
+*threat agent* and the *threat type*. Each threat is given a *risk rating*
+that represents the impact and likelihood of that threat. We also discuss
+potential mitigations.
+
+Assets
+======
+
+We have identified the following assets for TF-A:
+
+.. table:: Table 2: TF-A Assets
+
+  +--------------------+---------------------------------------------------+
+  | Asset              | Description                                       |
+  +====================+===================================================+
+  | Sensitive Data     | | These include sensitive data that an attacker   |
+  |                    |   must not be able to tamper with (e.g. the Root  |
+  |                    |   of Trust Public Key) or see (e.g. secure logs,  |
+  |                    |   debugging information such as crash reports).   |
+  +--------------------+---------------------------------------------------+
+  | Code Execution     | | This represents the requirement that the        |
+  |                    |   platform should run only TF-A code approved by  |
+  |                    |   the platform provider.                          |
+  +--------------------+---------------------------------------------------+
+  | Availability       | | This represents the requirement that TF-A       |
+  |                    |   services should always be available for use.    |
+  +--------------------+---------------------------------------------------+
+
+Threat Agents
+=============
+
+To understand the attack surface, it is important to identify potential
+attackers, i.e. attack entry points. The following threat agents are
+in scope of this threat model.
+
+.. table:: Table 3: Threat Agents
+
+  +-------------------+-------------------------------------------------------+
+  | Threat Agent      | Description                                           |
+  +===================+=======================================================+
+  |   NSCode          | | Malicious or faulty code running in the Non-secure  |
+  |                   |   world, including NS-EL0 NS-EL1 and NS-EL2 levels    |
+  +-------------------+-------------------------------------------------------+
+  |   SecCode         | | Malicious or faulty code running in the secure      |
+  |                   |   world, including S-EL0 and S-EL1 levels             |
+  +-------------------+-------------------------------------------------------+
+  |   AppDebug        | | Physical attacker using  debug signals to access    |
+  |                   |   TF-A resources                                      |
+  +-------------------+-------------------------------------------------------+
+  |  PhysicalAccess   | | Physical attacker having access to external device  |
+  |                   |   communication bus and to external flash             |
+  |                   |   communication bus using common hardware             |
+  +-------------------+-------------------------------------------------------+
+
+.. note::
+
+  In this threat model an advanced physical attacker that has the capability
+  to tamper with a hardware (e.g. "rewiring" a chip using a focused
+  ion beam (FIB) workstation or decapsulate the chip using chemicals) is
+  considered out-of-scope.
+
+Threat Types
+============
+
+In this threat model we categorize threats using the `STRIDE threat
+analysis technique`_. In this technique a threat is categorized as one
+or more of these types: ``Spoofing``, ``Tampering``, ``Repudiation``,
+``Information disclosure``, ``Denial of service`` or
+``Elevation of privilege``.
+
+Threat Risk Ratings
+===================
+
+For each threat identified, a risk rating that ranges
+from *informational* to *critical* is given based on the likelihood of the
+threat occuring if a mitigation is not in place, and the impact of the
+threat (i.e. how severe the consequences could be). Table 4 explains each
+rating in terms of score, impact and likelihood.
+
+.. table:: Table 4: Rating and score as applied to impact and likelihood
+
+  +-----------------------+-------------------------+---------------------------+
+  | **Rating (Score)**    | **Impact**              | **Likelihood**            |
+  +=======================+=========================+===========================+
+  | Critical (5)          | | Extreme impact to     | | Threat is almost        |

+  |                       |                         | | Knowledge of the threat |
+  |                       |                         |   and how to exploit it   |
+  |                       |                         |   are in the public       |

+  |                       |   combined with other   |                           |
+  |                       |   threats.              |                           |
+  +-----------------------+-------------------------+---------------------------+
+
+Aggregate risk scores are assigned to identified threats;
+specifically, the impact score multiplied by the likelihood score.
+For example, a threat with high likelihood and low impact would have an
+aggregate risk score of eight (8); that is, four (4) for high likelihood
+multiplied by two (2) for low impact. The aggregate risk score determines
+the finding's overall risk level, as shown in the following table.
+
+.. table:: Table 5: Overall risk levels and corresponding aggregate scores
+
+  +---------------------+-----------------------------------+
+  | Overall Risk Level  | Aggregate Risk Score              |
+  |                     | (Impact multiplied by Likelihood) |
+  +=====================+===================================+
+  | Critical            | 20–25                             |
+  +---------------------+-----------------------------------+
+  | High                | 12–19                             |
+  +---------------------+-----------------------------------+
+  | Medium              | 6–11                              |
+  +---------------------+-----------------------------------+
+  | Low                 | 2–5                               |
+  +---------------------+-----------------------------------+
+  | Informational       | 1                                 |
+  +---------------------+-----------------------------------+
+
+The likelihood and impact of a threat depends on the
+target environment in which TF-A is running. For example, attacks
+that require physical access are unlikely in server environments while
+they are more common in Internet of Things(IoT) environments.
+In this threat model we consider three target environments:
+``Internet of Things(IoT)``, ``Mobile`` and ``Server``.
+
+Threat Assessment
+=================
+
+The following threats were identified by applying STRIDE analysis on
+each diagram element of the data flow diagram.
+
+For each threat, we strive to indicate whether the mitigations are currently
+implemented or not. However, the answer to this question is not always straight
+forward. Some mitigations are partially implemented in the generic code but also
+rely on the platform code to implement some bits of it. This threat model aims
+to be platform-independent and it is important to keep in mind that such threats
+only get mitigated if the platform code properly fulfills its responsibilities.
+
+Also, some mitigations require enabling specific features, which must be
+explicitly turned on via a build flag.
+
+These are highlighted in the ``Mitigations implemented?`` box.

+EL3 SPMC Threat Model
+*********************
+
+************
+Introduction
+************
+This document provides a threat model for the TF-A `EL3 Secure Partition Manager`_
+(EL3 SPM) implementation. The EL3 SPM implementation is based on the
+`Arm Firmware Framework for Arm A-profile`_ specification.
+
+********************
+Target of Evaluation
+********************
+In this threat model, the target of evaluation is the ``Secure Partition Manager Core``
+component (SPMC) within the EL3 firmware.
+The monitor and SPMD at EL3 are covered by the `Generic TF-A threat model`_.
+
+The scope for this threat model is:
+
+- The TF-A implementation for the EL3 SPMC
+- The implementation complies with the FF-A v1.1 specification.
+- Secure partition is statically provisioned at boot time.
+- Focus on the run-time part of the life-cycle (no specific emphasis on boot
+  time, factory firmware provisioning, firmware udpate etc.)
+- Not covering advanced or invasive physical attacks such as decapsulation,
+  FIB etc.
+
+Data Flow Diagram
+=================
+Figure 1 shows a high-level data flow diagram for the SPM split into an SPMD
+and SPMC component at EL3. The SPMD mostly acts as a relayer/pass-through between
+the normal world and the secure world. It is assumed to expose small attack surface.
+
+A description of each diagram element is given in Table 1. In the diagram, the
+red broken lines indicate trust boundaries.
+
+Components outside of the broken lines are considered untrusted.

+Threat Analysis
+***************
+
+This threat model follows a similar methodology to the `Generic TF-A threat model`_.
+The following sections define:
+
+- Trust boundaries
+- Assets
+- Theat agents
+- Threat types
+
+Trust boundaries
+================
+
+- Normal world is untrusted.
+- Secure world and normal world are separate trust boundaries.
+- EL3 monitor, SPMD and SPMC are trusted.
+- Bootloaders (in particular BL1/BL2 if using TF-A) and run-time BL31 are
+  implicitely trusted by the usage of trusted boot.
+- EL3 monitor, SPMD, SPMC do not trust SPs.
+
+Assets
+======
+
+The following assets are identified:
+
+- SPMC state.
+- SP state.
+- Information exchange between endpoints (partition messages).
+- SPMC secrets (e.g. pointer authentication key when enabled)
+- SP secrets (e.g. application keys).
+- Scheduling cycles.
+- Shared memory.
+
+Threat Agents
+=============
+
+The following threat agents are identified:
+
+- Non-secure endpoint (referred NS-Endpoint later): normal world client at
+  NS-EL2 (Hypervisor) or NS-EL1 (VM or OS kernel).
+- Secure endpoint (referred as S-Endpoint later): typically a secure partition.
+- Hardware attacks (non-invasive) requiring a physical access to the device,
+  such as bus probing or DRAM stress.
+
+Threat types
+============
+
+The following threat categories as exposed in the `Generic TF-A threat model`_
+are re-used:
+
+- Spoofing
+- Tampering
+- Repudiation
+- Information disclosure
+- Denial of service
+- Elevation of privileges
+
+Similarly this threat model re-uses the same threat risk ratings. The risk
+analysis is evaluated based on the environment being ``Server`` or ``Mobile``.
+IOT is not evaluated as the EL3 SPMC is primarily meant for use in Client.
+
+Threat Assessment
+=================
+
+The following threats are identified by applying STRIDE analysis on each diagram
+element of the data flow diagram.

+fvp_r-Platform Threat Model
+***************************
+
+************************
+Introduction
+************************
+This document provides a threat model for TF-A fvp_r platform.
+
+************************
+Target of Evaluation
+************************
+In this threat model, the target of evaluation is the fvp_r platform of Trusted
+Firmware for A-class Processors (TF-A).  The fvp_r platform provides limited
+support of AArch64 R-class Processors (v8-R64).
+
+This is a delta document, only pointing out differences from the general TF-A
+threat-model document, :ref:`Generic Threat Model`
+
+BL1 Only
+========
+The most fundamental difference between the threat model for the current fvp_r
+implementation compared to the general TF-A threat model, is that fvp_r is
+currently limited to BL1 only.  Any threats from the general TF-A threat model
+unrelated to BL1 are therefore not relevant to the fvp_r implementation.
+
+The fvp_r BL1 implementation directly loads a customer/partner-defined runtime
+system.  The threat model for that runtime system, being partner-defined, is
+out-of-scope for this threat-model.
+
+Relatedly, all exceptions, synchronous and asynchronous, are disabled during BL1
+execution.  So, any references to exceptions are not relevant.
+
+EL3 is Unsupported and All Secure
+=================================
+v8-R64 cores do not support EL3, and (essentially) all operation is defined as
+Secure-mode.  Therefore:
+
+    - Any threats regarding NS operation are not relevant.
+
+    - Any mentions of SMCs are also not relevant.
+
+    - Anything otherwise-relevant code running in EL3 is instead run in EL2.
+
+MPU instead of MMU
+==================
+v8-R64 cores, running in EL2, use an MPU for memory management, rather than an
+MMU.  The MPU in the fvp_r implementation is configured to function effectively
+identically with the MMU for the usual BL1 implementation.  There are
+memory-map differences, but the MPU configuration is functionally equivalent.
+
+No AArch32 Support
+==================
+Another substantial difference between v8-A and v8-R64 cores is that v8-R64 does
+not support AArch32.  However, this is not believed to have any threat-modeling
+ramifications.
+
+
+Threat Assessment
+=================
+For this section, please reference the Threat Assessment under the general TF-A
+threat-model document, :ref:`Generic Threat Model`
+
+The following threats from that document are still relevant to the fvp_r
+implementation:
+
+    - ID 01:  An attacker can mangle firmware images to execute arbitrary code.
+
+    - ID 03:  An attacker can use Time-of-Check-Time-of-Use (TOCTOU) attack to
+      bypass image authentication during the boot process.
+
+    - ID 04:  An attacker with physical access can execute arbitrary image by
+      bypassing the signature verification stage using clock- or power-glitching
+      techniques.
+
+    - ID 05:  Information leak via UART logs such as crashes
+
+    - ID 06:  An attacker can read sensitive data and execute arbitrary code
+      through the external debug and trace interface.
+
+    - ID 08:  Memory corruption due to memory overflows and lack of boundary
+      checking when accessing resources could allow an attacker to execute 
+      arbitrary code, modify some state variable to change the normal flow of
+      the program, or leak sensitive.
+
+    - ID 11:  Misconfiguration of the Memory Protection Unit (MPU) may allow
+      normal world software to access sensitive data or execute arbitrary code.
+      Arguably, MPUs having fewer memory regions, there may be a temptation to
+      share memory regions, making this a greater threat.  However, since the
+      fvp_r implementation is limited to BL1, since BL1's regions are fixed,
+      and since the MPU configuration is equivalent with that for the fvp
+      platform and others, this is not expected to be a concern.

+SPMC Threat Model
+*****************
+
+************************
+Introduction
+************************
+This document provides a threat model for the TF-A `Secure Partition Manager`_
+(SPM) implementation or more generally the S-EL2 reference firmware running on
+systems implementing the FEAT_SEL2 (formerly Armv8.4 Secure EL2) architecture
+extension. The SPM implementation is based on the `Arm Firmware Framework for
+Arm A-profile`_ specification.
+
+In brief, the broad FF-A specification and S-EL2 firmware implementation
+provide:
+
+- Isolation of mutually mistrusting SW components, or endpoints in the FF-A
+  terminology.
+- Distinct sandboxes in the secure world called secure partitions. This permits
+  isolation of services from multiple vendors.
+- A standard protocol for communication and memory sharing between FF-A
+  endpoints.
+- Mutual isolation of the normal world and the secure world (e.g. a Trusted OS
+  is prevented to map an arbitrary NS physical memory region such as the kernel
+  or the Hypervisor).
+
+************************
+Target of Evaluation
+************************
+In this threat model, the target of evaluation is the S-EL2 firmware or the
+``Secure Partition Manager Core`` component (SPMC).
+The monitor and SPMD at EL3 are covered by the `Generic TF-A threat model`_.
+
+The scope for this threat model is:
+
+- The TF-A implementation for the S-EL2 SPMC based on the Hafnium hypervisor
+  running in the secure world of TrustZone (at S-EL2 exception level).
+  The threat model is not related to the normal world Hypervisor or VMs.
+  The S-EL1 SPMC solution is not covered.
+- The implementation complies with the FF-A v1.0 specification, and a few
+  features of FF-A v1.1 specification.
+- Secure partitions are statically provisioned at boot time.
+- Focus on the run-time part of the life-cycle (no specific emphasis on boot
+  time, factory firmware provisioning, firmware udpate etc.)
+- Not covering advanced or invasive physical attacks such as decapsulation,
+  FIB etc.
+- Assumes secure boot or in particular TF-A trusted boot (TBBR or dual CoT) is
+  enabled. An attacker cannot boot arbitrary images that are not approved by the
+  SiP or platform providers.
+
+Data Flow Diagram
+======================
+Figure 1 shows a high-level data flow diagram for the SPM split into an SPMD
+component at EL3 and an SPMC component at S-EL2. The SPMD mostly acts as a
+relayer/pass-through between the normal world and the secure world. It is
+assumed to expose small attack surface.
+
+A description of each diagram element is given in Table 1. In the diagram, the
+red broken lines indicate trust boundaries.
+
+Components outside of the broken lines are considered untrusted.

+Threat Analysis
+*********************
+
+This threat model follows a similar methodology to the `Generic TF-A threat model`_.
+The following sections define:
+
+- Trust boundaries
+- Assets
+- Theat agents
+- Threat types
+
+Trust boundaries
+============================
+
+- Normal world is untrusted.
+- Secure world and normal world are separate trust boundaries.
+- EL3 monitor, SPMD and SPMC are trusted.
+- Bootloaders (in particular BL1/BL2 if using TF-A) and run-time BL31 are
+  implicitely trusted by the usage of secure boot.
+- EL3 monitor, SPMD, SPMC do not trust SPs.
+
+.. figure:: ../resources/diagrams/spm-threat-model-trust-boundaries.png
+
+    Figure 2: Trust boundaries
+
+Assets
+============================
+
+The following assets are identified:
+
+- SPMC state.
+- SP state.
+- Information exchange between endpoints (partition messages).
+- SPMC secrets (e.g. pointer authentication key when enabled)
+- SP secrets (e.g. application keys).
+- Scheduling cycles.
+- Shared memory.
+
+Threat Agents
+============================
+
+The following threat agents are identified:
+
+- NS-Endpoint identifies a non-secure endpoint: normal world client at NS-EL2
+  (Hypervisor) or NS-EL1 (VM or OS kernel).
+- S-Endpoint identifies a secure endpoint typically a secure partition.
+- Hardware attacks (non-invasive) requiring a physical access to the device,
+  such as bus probing or DRAM stress.
+
+Threat types
+============================
+
+The following threat categories as exposed in the `Generic TF-A threat model`_
+are re-used:
+
+- Spoofing
+- Tampering
+- Repudiation
+- Information disclosure
+- Denial of service
+- Elevation of privileges
+
+Similarly this threat model re-uses the same threat risk ratings. The risk
+analysis is evaluated based on the environment being ``Server`` or ``Mobile``.
+
+Threat Assessment
+============================
+
+The following threats are identified by applying STRIDE analysis on each diagram
+element of the data flow diagram.

+|                        | spoof the origin and destination worlds (e.g. a NWd|

+| ``Threat``             | **A malicious secure endpoint might not deactivate |
+|                        | a virtual interrupt signaled to it by the SPMC but |
+|                        | perform secure interrupt signal completion. This   |

+|                        | could lead to an unknown state and further lead to |

+|                        | deliberately not perform either interrupt          |
+|                        | deactivation or interrupt completion signal. Since,|
+|                        | the SPMC can only process one secure interrupt at a|
+|                        | time, this could choke the system where all        |
+|                        | interrupts are indefinitely masked which could     |

+|                        | provisions CPU cycles to run a secure endpoint     |

+ *	detection is based on the platform entrypoint address : if it is zero
+ *	then it is a cold boot, otherwise it is a warm boot. In the latter case,

+ *
+ *  _secondary_cold_boot:
+ *	Whether the macro needs to identify the CPU that is calling it: primary
+ *	CPU or secondary CPU. The primary CPU will be allowed to carry on with
+ *	the platform initialisations, while the secondaries will be put in a
+ *	platform-specific state in the meantime.
+ *
+ *	If the caller knows this macro will only be called by the primary CPU
+ *	then this parameter can be defined to 0 to skip this step.

+ *	Whether the macro needs to initialise the C runtime environment.

+ * This structure describes some of the implementation defined attributes of the
+ * GICv3 IP. It is used by the platform port to specify these attributes in order
+ * to initialise the GICV3 driver. The attributes are described below.
+ *
+ * The 'gicd_base' field contains the base address of the Distributor interface
+ * programmer's view.
+ *
+ * The 'gicr_base' field contains the base address of the Re-distributor
+ * interface programmer's view.
+ *
+ * The 'interrupt_props' field is a pointer to an array that enumerates secure
+ * interrupts and their properties. If this field is not NULL, both
+ * 'g0_interrupt_array' and 'g1s_interrupt_array' fields are ignored.
+ *
+ * The 'interrupt_props_num' field contains the number of entries in the
+ * 'interrupt_props' array. If this field is non-zero, both 'g0_interrupt_num'
+ * and 'g1s_interrupt_num' are ignored.
+ *
+ * The 'rdistif_num' field contains the number of Redistributor interfaces the
+ * GIC implements. This is equal to the number of CPUs or CPU interfaces
+ * instantiated in the GIC.
+ *
+ * The 'rdistif_base_addrs' field is a pointer to an array that has an entry for
+ * storing the base address of the Redistributor interface frame of each CPU in
+ * the system. The size of the array = 'rdistif_num'. The base addresses are
+ * detected during driver initialisation.
+ *
+ * The 'mpidr_to_core_pos' field is a pointer to a hash function which the
+ * driver will use to convert an MPIDR value to a linear core index. This index
+ * will be used for accessing the 'rdistif_base_addrs' array. This is an
+ * optional field. A GICv3 implementation maps each MPIDR to a linear core index
+ * as well. This mapping can be found by reading the "Affinity Value" and
+ * "Processor Number" fields in the GICR_TYPER. It is IMP. DEF. if the
+ * "Processor Numbers" are suitable to index into an array to access core
+ * specific information. If this not the case, the platform port must provide a
+ * hash function. Otherwise, the "Processor Number" field will be used to access

+All headers under include/export/ are export headers that are intended for
+inclusion in third-party code which needs to interact with TF-A data structures
+or interfaces. They must follow these special rules:
+
+- Header guards should start with ARM_TRUSTED_FIRMWARE_ to reduce clash risk.
+
+- All definitions should be sufficiently namespaced (e.g. with BL_ or TF_) to
+  make name clashes with third-party code unlikely.
+
+- They must not #include any headers except other export headers, and those
+  includes must use relative paths with "../double_quotes.h" notation.
+
+- They must not rely on any type definitions other that <stdint.h> types defined
+  in the ISO C standard (i.e. uint64_t is fine, but not u_register_t). They
+  should still not #include <stdint.h>. Instead, wrapper headers including
+  export headers need to ensure that they #include <stdint.h> earlier in their
+  include order.
+
+- They must not rely on any macro definitions other than those which are
+  pre-defined by all common compilers (e.g. __ASSEMBLER__ or __aarch64__).
+
+- They must only contain macro, type and structure definitions, no prototypes.
+
+- They should avoid using integer types with architecture-dependent widths
+  (e.g. long, uintptr_t, pointer types) where possible. (Some existing export
+  headers are violating this for now.)
+
+- Their names should always end in "_exp.h".
+
+- Normal TF-A code should never include export headers directly. Instead, it
+  should include a wrapper header that ensures the export header is included in
+  the right manner. (The wrapper header for include/export/x/y/z_exp.h should
+  normally be placed at include/x/y/z.h.)

+ * of the public delegated key to make a cryptographical binding (hash lock)

+ * The initial attestation token has two roles in this scenario:
+ *   - Attest the device boot status and security lifecycle.
+ *   - Attest the delegated attestation key.
+ * The delegated attestation key is derived from a preprovisioned seed. The
+ * input for the key derivation is the platform boot status. The system can be

+ * key_bits      The size of the requested attestation key, in bits.
+ * key_buf       Pointer to the buffer where the delegated attestation key will

+ * key_buf_size  Size of allocated buffer for the key, in bytes.

+ *               attestation token.

+
+  Polynomials over GF(2) are represented in binary, one bit per coefficient,
+  with the lowest powers in the most significant bit. Then adding polynomials

+  byte 0xb1 is the polynomial x^7+x^3+x^2+1), then the CRC is (q*x^32) mod p,
+  where a mod b means the remainder after dividing a by b.
+
+  This calculation is done using the shift-register method of multiplying and
+  taking the remainder. The register is initialized to zero, and for each
+  incoming bit, x^32 is added mod p to the register if the bit is a one (where
+  x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by x
+  (which is shifting right by one and adding x^32 mod p if the bit shifted out
+  is a one). We start with the highest power (least significant bit) of q and
+  repeat for all eight bits of q.
+
+  The table is simply the CRC of all possible eight bit values. This is all the
+  information needed to generate CRCs on data a byte at a time for all

+/*
+   Decode literal, length, and distance codes and write out the resulting
+   literal and match bytes until either not enough input or output is
+   available, an end-of-block is encountered, or a data error is encountered.
+   When large enough input and output buffers are supplied to inflate(), for
+   example, a 16K input buffer and a 64K output buffer, more than 95% of the
+   inflate execution time is spent in this routine.
+
+   Entry assumptions:
+
+        state->mode == LEN
+        strm->avail_in >= 6
+        strm->avail_out >= 258
+        start >= strm->avail_out
+        state->bits < 8
+
+   On return, state->mode is one of:
+
+        LEN -- ran out of enough output space or enough available input
+        TYPE -- reached end of block code, inflate() to interpret next block
+        BAD -- error in block data
+
+   Notes:
+
+    - The maximum input bits used by a length/distance pair is 15 bits for the
+      length code, 5 bits for the length extra, 15 bits for the distance code,
+      and 13 bits for the distance extra.  This totals 48 bits, or six bytes.
+      Therefore if strm->avail_in >= 6, then there is enough input to avoid
+      checking for available input while decoding.
+
+    - The maximum bytes that a single length/distance pair can output is 258
+      bytes, which is the maximum length that can be coded.  inflate_fast()
+      requires strm->avail_out >= 258 for each loop to avoid checking for
+      output space.

+/* inflate.c -- zlib decompression
+ * Copyright (C) 1995-2022 Mark Adler
+ * For conditions of distribution and use, see copyright notice in zlib.h
+ */
+
+/*
+ * Change history:
+ *
+ * 1.2.beta0    24 Nov 2002
+ * - First version -- complete rewrite of inflate to simplify code, avoid
+ *   creation of window when not needed, minimize use of window when it is
+ *   needed, make inffast.c even faster, implement gzip decoding, and to
+ *   improve code readability and style over the previous zlib inflate code
+ *
+ * 1.2.beta1    25 Nov 2002
+ * - Use pointers for available input and output checking in inffast.c
+ * - Remove input and output counters in inffast.c
+ * - Change inffast.c entry and loop from avail_in >= 7 to >= 6
+ * - Remove unnecessary second byte pull from length extra in inffast.c
+ * - Unroll direct copy to three copies per loop in inffast.c
+ *
+ * 1.2.beta2    4 Dec 2002
+ * - Change external routine names to reduce potential conflicts
+ * - Correct filename to inffixed.h for fixed tables in inflate.c
+ * - Make hbuf[] unsigned char to match parameter type in inflate.c
+ * - Change strm->next_out[-state->offset] to *(strm->next_out - state->offset)
+ *   to avoid negation problem on Alphas (64 bit) in inflate.c
+ *
+ * 1.2.beta3    22 Dec 2002
+ * - Add comments on state->bits assertion in inffast.c
+ * - Add comments on op field in inftrees.h
+ * - Fix bug in reuse of allocated window after inflateReset()
+ * - Remove bit fields--back to byte structure for speed
+ * - Remove distance extra == 0 check in inflate_fast()--only helps for lengths
+ * - Change post-increments to pre-increments in inflate_fast(), PPC biased?
+ * - Add compile time option, POSTINC, to use post-increments instead (Intel?)
+ * - Make MATCH copy in inflate() much faster for when inflate_fast() not used
+ * - Use local copies of stream next and avail values, as well as local bit
+ *   buffer and bit count in inflate()--for speed when inflate_fast() not used
+ *
+ * 1.2.beta4    1 Jan 2003
+ * - Split ptr - 257 statements in inflate_table() to avoid compiler warnings
+ * - Move a comment on output buffer sizes from inffast.c to inflate.c
+ * - Add comments in inffast.c to introduce the inflate_fast() routine
+ * - Rearrange window copies in inflate_fast() for speed and simplification
+ * - Unroll last copy for window match in inflate_fast()
+ * - Use local copies of window variables in inflate_fast() for speed
+ * - Pull out common wnext == 0 case for speed in inflate_fast()
+ * - Make op and len in inflate_fast() unsigned for consistency
+ * - Add FAR to lcode and dcode declarations in inflate_fast()
+ * - Simplified bad distance check in inflate_fast()
+ * - Added inflateBackInit(), inflateBack(), and inflateBackEnd() in new
+ *   source file infback.c to provide a call-back interface to inflate for
+ *   programs like gzip and unzip -- uses window as output buffer to avoid
+ *   window copying
+ *
+ * 1.2.beta5    1 Jan 2003
+ * - Improved inflateBack() interface to allow the caller to provide initial
+ *   input in strm.
+ * - Fixed stored blocks bug in inflateBack()
+ *
+ * 1.2.beta6    4 Jan 2003
+ * - Added comments in inffast.c on effectiveness of POSTINC
+ * - Typecasting all around to reduce compiler warnings
+ * - Changed loops from while (1) or do {} while (1) to for (;;), again to
+ *   make compilers happy
+ * - Changed type of window in inflateBackInit() to unsigned char *
+ *
+ * 1.2.beta7    27 Jan 2003
+ * - Changed many types to unsigned or unsigned short to avoid warnings
+ * - Added inflateCopy() function
+ *
+ * 1.2.0        9 Mar 2003
+ * - Changed inflateBack() interface to provide separate opaque descriptors
+ *   for the in() and out() functions
+ * - Changed inflateBack() argument and in_func typedef to swap the length
+ *   and buffer address return values for the input function

+   inflate() uses a state machine to process as much input data and generate as
+   much output data as possible before returning.  The state machine is
+   structured roughly as follows:
+
+    for (;;) switch (state) {
+    ...
+    case STATEn:
+        if (not enough input data or output space to make progress)
+            return;
+        ... make progress ...
+        state = STATEm;
+        break;
+    ...
+    }
+
+   so when inflate() is called again, the same case is attempted again, and
+   if the appropriate resources are provided, the machine proceeds to the
+   next state.  The NEEDBITS() macro is usually the way the state evaluates
+   whether it can proceed or should return.  NEEDBITS() does the return if
+   the requested bits are not available.  The typical use of the BITS macros
+   is:
+
+        NEEDBITS(n);
+        ... do something with BITS(n) ...
+        DROPBITS(n);
+
+   where NEEDBITS(n) either returns from inflate() if there isn't enough
+   input left to load n bits into the accumulator, or it continues.  BITS(n)
+   gives the low n bits in the accumulator.  When done, DROPBITS(n) drops
+   the low n bits off the accumulator.  INITBITS() clears the accumulator
+   and sets the number of available bits to zero.  BYTEBITS() discards just
+   enough bits to put the accumulator on a byte boundary.  After BYTEBITS()
+   and a NEEDBITS(8), then BITS(8) would return the next byte in the stream.
+
+   NEEDBITS(n) uses PULLBYTE() to get an available byte of input, or to return
+   if there is no input available.  The decoding of variable length codes uses
+   PULLBYTE() directly in order to pull just enough bytes to decode the next
+   code, and no more.
+
+   Some states loop until they get enough input, making sure that enough
+   state information is maintained to continue the loop where it left off
+   if NEEDBITS() returns in the loop.  For example, want, need, and keep
+   would all have to actually be part of the saved state in case NEEDBITS()
+   returns:
+
+    case STATEw:
+        while (want < need) {
+            NEEDBITS(n);
+            keep[want++] = BITS(n);
+            DROPBITS(n);
+        }
+        state = STATEx;
+    case STATEx:
+
+   As shown above, if the next state is also the next case, then the break
+   is omitted.
+
+   A state may also return if there is not enough output space available to
+   complete that state.  Those states are copying stored data, writing a
+   literal byte, and copying a matching string.
+
+   When returning, a "goto inf_leave" is used to update the total counters,
+   update the check value, and determine whether any progress has been made
+   during that inflate() call in order to return the proper return code.
+   Progress is defined as a change in either strm->avail_in or strm->avail_out.
+   When there is a window, goto inf_leave will update the window with the last
+   output written.  If a goto inf_leave occurs in the middle of decompression
+   and there is no window currently, goto inf_leave will create one and copy
+   output to the window for the next call of inflate().
+
+   In this implementation, the flush parameter of inflate() only affects the
+   return code (per zlib.h).  inflate() always writes as much as possible to
+   strm->next_out, given the space available and the provided input--the effect
+   documented in zlib.h of Z_SYNC_FLUSH.  Furthermore, inflate() always defers
+   the allocation of and copying into a sliding window until necessary, which
+   provides the effect documented in zlib.h for Z_FINISH when the entire input
+   stream available.  So the only thing the flush parameter actually does is:
+   when flush is set to Z_FINISH, inflate() cannot return Z_OK.  Instead it
+   will return Z_BUF_ERROR if it has not reached the end of the stream.

+       for codes with equal lengths.  Then the code starts with all zero bits
+       for the first code of the shortest length, and the codes are integer

+       are incremented backwards.

+       1..MAXBITS is interpreted as that code length.  zero means that that
+       symbol does not occur in this code.
+
+       The codes are sorted by computing a count of codes for each length,
+       creating from that a table of starting indices for each length in the
+       sorted table, and then entering the symbols in order in the sorted
+       table.  The sorted table is work[], with that space being provided by
+       the caller.
+
+       The length counts are used for other purposes as well, i.e. finding
+       the minimum and maximum length codes, determining if there are any
+       codes at all, checking for a valid set of lengths, and looking ahead
+       at length counts to determine sub-table sizes when building the

+/*
+    The 'zlib' compression library provides in-memory compression and
+  decompression functions, including integrity checks of the uncompressed data.
+  This version of the library supports only one compression method (deflation)
+  but other algorithms will be added later and will have the same stream
+  interface.
+
+    Compression can be done in a single step if the buffers are large enough,
+  or can be done by repeated calls of the compression function.  In the latter
+  case, the application must provide more input and/or consume the output
+  (providing more output space) before each call.
+
+    The compressed data format used by default by the in-memory functions is
+  the zlib format, which is a zlib wrapper documented in RFC 1950, wrapped
+  around a deflate stream, which is itself documented in RFC 1951.
+
+    The library also supports reading and writing files in gzip (.gz) format
+  with an interface similar to that of stdio using the functions that start
+  with "gz".  The gzip format is different from the zlib format.  gzip is a
+  gzip wrapper, documented in RFC 1952, wrapped around a deflate stream.
+
+    This library can optionally read and write gzip and raw deflate streams in
+  memory as well.
+
+    The zlib format was designed to be compact and fast for use in memory
+  and on communications channels.  The gzip format was designed for single-
+  file compression on file systems, has a larger header than zlib to maintain
+  directory information, and uses a different, slower check method than zlib.
+
+    The library does not install any signal handler.  The decoder checks
+  the consistency of the compressed data, so the library should never crash
+  even in the case of corrupted input.

+   the library with -DMAX_WBITS=14 (see zconf.h).
+

+   if the decompressor wants to decompress everything in a single step).

+    deflate compresses as much data as possible, and stops when the input
+  buffer becomes empty or the output buffer becomes full.  It may introduce
+  some output latency (reading input without producing any output) except when
+  forced to flush.
+
+    The detailed semantics are as follows.  deflate performs one or both of the
+  following actions:
+
+  - Compress more input starting at next_in and update next_in and avail_in
+    accordingly.  If not all input can be processed (because there is not
+    enough room in the output buffer), next_in and avail_in are updated and
+    processing will resume at this point for the next call of deflate().
+
+  - Generate more output starting at next_out and update next_out and avail_out
+    accordingly.  This action is forced if the parameter flush is non zero.
+    Forcing flush frequently degrades the compression ratio, so this parameter
+    should be set only when necessary.  Some output may be provided even if
+    flush is zero.
+
+    Before the call of deflate(), the application should ensure that at least
+  one of the actions is possible, by providing more input and/or consuming more
+  output, and updating avail_in or avail_out accordingly; avail_out should
+  never be zero before the call.  The application can consume the compressed
+  output when it wants, for example when the output buffer is full (avail_out
+  == 0), or after each call of deflate().  If deflate returns Z_OK and with
+  zero avail_out, it must be called again after making room in the output
+  buffer because there might be more output pending. See deflatePending(),
+  which can be used if desired to determine whether or not there is more output
+  in that case.
+
+    Normally the parameter flush is set to Z_NO_FLUSH, which allows deflate to
+  decide how much data to accumulate before producing output, in order to
+  maximize compression.
+
+    If the parameter flush is set to Z_SYNC_FLUSH, all pending output is
+  flushed to the output buffer and the output is aligned on a byte boundary, so
+  that the decompressor can get all input data available so far.  (In
+  particular avail_in is zero after the call if enough output space has been
+  provided before the call.) Flushing may degrade compression for some
+  compression algorithms and so it should be used only when necessary.  This
+  completes the current deflate block and follows it with an empty stored block
+  that is three bits plus filler bits to the next byte, followed by four bytes
+  (00 00 ff ff).
+
+    If flush is set to Z_PARTIAL_FLUSH, all pending output is flushed to the
+  output buffer, but the output is not aligned to a byte boundary.  All of the
+  input data so far will be available to the decompressor, as for Z_SYNC_FLUSH.
+  This completes the current deflate block and follows it with an empty fixed
+  codes block that is 10 bits long.  This assures that enough bytes are output
+  in order for the decompressor to finish the block before the empty fixed
+  codes block.
+
+    If flush is set to Z_BLOCK, a deflate block is completed and emitted, as
+  for Z_SYNC_FLUSH, but the output is not aligned on a byte boundary, and up to
+  seven bits of the current block are held to be written as the next byte after
+  the next deflate block is completed.  In this case, the decompressor may not
+  be provided enough bits at this point in order to complete decompression of
+  the data provided so far to the compressor.  It may need to wait for the next
+  block to be emitted.  This is for advanced applications that need to control
+  the emission of deflate blocks.
+
+    If flush is set to Z_FULL_FLUSH, all output is flushed as with
+  Z_SYNC_FLUSH, and the compression state is reset so that decompression can
+  restart from this point if previous compressed data has been damaged or if
+  random access is desired.  Using Z_FULL_FLUSH too often can seriously degrade
+  compression.
+
+    If deflate returns with avail_out == 0, this function must be called again
+  with the same value of the flush parameter and more output space (updated
+  avail_out), until the flush is complete (deflate returns with non-zero
+  avail_out).  In the case of a Z_FULL_FLUSH or Z_SYNC_FLUSH, make sure that
+  avail_out is greater than six to avoid repeated flush markers due to
+  avail_out == 0 on return.
+
+    If the parameter flush is set to Z_FINISH, pending input is processed,
+  pending output is flushed and deflate returns with Z_STREAM_END if there was
+  enough output space.  If deflate returns with Z_OK or Z_BUF_ERROR, this
+  function must be called again with Z_FINISH and more output space (updated
+  avail_out) but no more input data, until it returns with Z_STREAM_END or an
+  error.  After deflate has returned Z_STREAM_END, the only possible operations
+  on the stream are deflateReset or deflateEnd.
+
+    Z_FINISH can be used in the first deflate call after deflateInit if all the
+  compression is to be done in a single step.  In order to complete in one
+  call, avail_out must be at least the value returned by deflateBound (see
+  below).  Then deflate is guaranteed to return Z_STREAM_END.  If not enough
+  output space is provided, deflate will not return Z_STREAM_END, and it must
+  be called again as described above.
+
+    deflate() sets strm->adler to the Adler-32 checksum of all input read
+  so far (that is, total_in bytes).  If a gzip stream is being generated, then
+  strm->adler will be the CRC-32 checksum of the input read so far.  (See
+  deflateInit2 below.)
+
+    deflate() may update strm->data_type if it can make a good guess about
+  the input data type (Z_BINARY or Z_TEXT).  If in doubt, the data is
+  considered binary.  This field is only for information purposes and does not
+  affect the compression algorithm in any manner.
+
+    deflate() returns Z_OK if some progress has been made (more input
+  processed or more output produced), Z_STREAM_END if all input has been
+  consumed and all output has been produced (only when flush is set to
+  Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for example
+  if next_in or next_out was Z_NULL or the state was inadvertently written over
+  by the application), or Z_BUF_ERROR if no progress is possible (for example
+  avail_in or avail_out was zero).  Note that Z_BUF_ERROR is not fatal, and

+    inflate decompresses as much data as possible, and stops when the input
+  buffer becomes empty or the output buffer becomes full.  It may introduce
+  some output latency (reading input without producing any output) except when
+  forced to flush.
+
+  The detailed semantics are as follows.  inflate performs one or both of the
+  following actions:
+
+  - Decompress more input starting at next_in and update next_in and avail_in
+    accordingly.  If not all input can be processed (because there is not
+    enough room in the output buffer), then next_in and avail_in are updated
+    accordingly, and processing will resume at this point for the next call of
+    inflate().
+
+  - Generate more output starting at next_out and update next_out and avail_out
+    accordingly.  inflate() provides as much output as possible, until there is
+    no more input data or no more space in the output buffer (see below about
+    the flush parameter).
+
+    Before the call of inflate(), the application should ensure that at least
+  one of the actions is possible, by providing more input and/or consuming more
+  output, and updating the next_* and avail_* values accordingly.  If the
+  caller of inflate() does not provide both available input and available
+  output space, it is possible that there will be no progress made.  The
+  application can consume the uncompressed output when it wants, for example
+  when the output buffer is full (avail_out == 0), or after each call of
+  inflate().  If inflate returns Z_OK and with zero avail_out, it must be
+  called again after making room in the output buffer because there might be
+  more output pending.
+
+    The flush parameter of inflate() can be Z_NO_FLUSH, Z_SYNC_FLUSH, Z_FINISH,
+  Z_BLOCK, or Z_TREES.  Z_SYNC_FLUSH requests that inflate() flush as much
+  output as possible to the output buffer.  Z_BLOCK requests that inflate()
+  stop if and when it gets to the next deflate block boundary.  When decoding
+  the zlib or gzip format, this will cause inflate() to return immediately
+  after the header and before the first block.  When doing a raw inflate,
+  inflate() will go ahead and process the first block, and will return when it
+  gets to the end of that block, or when it runs out of data.
+
+    The Z_BLOCK option assists in appending to or combining deflate streams.
+  To assist in this, on return inflate() always sets strm->data_type to the
+  number of unused bits in the last byte taken from strm->next_in, plus 64 if
+  inflate() is currently decoding the last block in the deflate stream, plus
+  128 if inflate() returned immediately after decoding an end-of-block code or
+  decoding the complete header up to just before the first byte of the deflate
+  stream.  The end-of-block will not be indicated until all of the uncompressed
+  data from that block has been written to strm->next_out.  The number of
+  unused bits may in general be greater than seven, except when bit 7 of
+  data_type is set, in which case the number of unused bits will be less than
+  eight.  data_type is set as noted here every time inflate() returns for all
+  flush options, and so can be used to determine the amount of currently
+  consumed input in bits.
+
+    The Z_TREES option behaves as Z_BLOCK does, but it also returns when the
+  end of each deflate block header is reached, before any actual data in that
+  block is decoded.  This allows the caller to determine the length of the
+  deflate block header for later use in random access within a deflate block.
+  256 is added to the value of strm->data_type when inflate() returns
+  immediately after reaching the end of the deflate block header.
+
+    inflate() should normally be called until it returns Z_STREAM_END or an
+  error.  However if all decompression is to be performed in a single step (a
+  single call of inflate), the parameter flush should be set to Z_FINISH.  In
+  this case all pending input is processed and all pending output is flushed;
+  avail_out must be large enough to hold all of the uncompressed data for the
+  operation to complete.  (The size of the uncompressed data may have been
+  saved by the compressor for this purpose.)  The use of Z_FINISH is not
+  required to perform an inflation in one step.  However it may be used to
+  inform inflate that a faster approach can be used for the single inflate()
+  call.  Z_FINISH also informs inflate to not maintain a sliding window if the
+  stream completes, which reduces inflate's memory footprint.  If the stream
+  does not complete, either because not all of the stream is provided or not
+  enough output space is provided, then a sliding window will be allocated and
+  inflate() can be called again to continue the operation as if Z_NO_FLUSH had
+  been used.
+
+     In this implementation, inflate() always flushes as much output as
+  possible to the output buffer, and always uses the faster approach on the
+  first call.  So the effects of the flush parameter in this implementation are
+  on the return value of inflate() as noted below, when inflate() returns early
+  when Z_BLOCK or Z_TREES is used, and when inflate() avoids the allocation of
+  memory for a sliding window when Z_FINISH is used.
+
+     If a preset dictionary is needed after this call (see inflateSetDictionary
+  below), inflate sets strm->adler to the Adler-32 checksum of the dictionary
+  chosen by the compressor and returns Z_NEED_DICT; otherwise it sets
+  strm->adler to the Adler-32 checksum of all output produced so far (that is,
+  total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described
+  below.  At the end of the stream, inflate() checks that its computed Adler-32
+  checksum is equal to that saved by the compressor and returns Z_STREAM_END
+  only if the checksum is correct.
+
+    inflate() can decompress and check either zlib-wrapped or gzip-wrapped
+  deflate data.  The header type is detected automatically, if requested when
+  initializing with inflateInit2().  Any information contained in the gzip
+  header is not retained unless inflateGetHeader() is used.  When processing
+  gzip-wrapped deflate data, strm->adler32 is set to the CRC-32 of the output
+  produced so far.  The CRC-32 is checked against the gzip trailer, as is the
+  uncompressed length, modulo 2^32.
+
+    inflate() returns Z_OK if some progress has been made (more input processed
+  or more output produced), Z_STREAM_END if the end of the compressed data has
+  been reached and all uncompressed output has been produced, Z_NEED_DICT if a
+  preset dictionary is needed at this point, Z_DATA_ERROR if the input data was
+  corrupted (input stream not conforming to the zlib format or incorrect check
+  value, in which case strm->msg points to a string with a more specific
+  error), Z_STREAM_ERROR if the stream structure was inconsistent (for example
+  next_in or next_out was Z_NULL, or the state was inadvertently written over
+  by the application), Z_MEM_ERROR if there was not enough memory, Z_BUF_ERROR

+
+     This is another version of deflateInit with more compression options.  The
+   fields zalloc, zfree and opaque must be initialized before by the caller.
+
+     The method parameter is the compression method.  It must be Z_DEFLATED in
+   this version of the library.
+
+     The windowBits parameter is the base two logarithm of the window size
+   (the size of the history buffer).  It should be in the range 8..15 for this
+   version of the library.  Larger values of this parameter result in better
+   compression at the expense of memory usage.  The default value is 15 if
+   deflateInit is used instead.
+
+     For the current implementation of deflate(), a windowBits value of 8 (a
+   window size of 256 bytes) is not supported.  As a result, a request for 8
+   will result in 9 (a 512-byte window).  In that case, providing 8 to
+   inflateInit2() will result in an error when the zlib header with 9 is
+   checked against the initialization of inflate().  The remedy is to not use 8
+   with deflateInit2() with this initialization, or at least in that case use 9
+   with inflateInit2().
+
+     windowBits can also be -8..-15 for raw deflate.  In this case, -windowBits
+   determines the window size.  deflate() will then generate raw deflate data
+   with no zlib header or trailer, and will not compute a check value.
+
+     windowBits can also be greater than 15 for optional gzip encoding.  Add
+   16 to windowBits to write a simple gzip header and trailer around the
+   compressed data instead of a zlib wrapper.  The gzip header will have no
+   file name, no extra data, no comment, no modification time (set to zero), no
+   header crc, and the operating system will be set to the appropriate value,
+   if the operating system was determined at compile time.  If a gzip stream is
+   being written, strm->adler is a CRC-32 instead of an Adler-32.
+
+     For raw deflate or gzip encoding, a request for a 256-byte window is
+   rejected as invalid, since only the zlib header provides a means of
+   transmitting the window size to the decompressor.
+
+     The memLevel parameter specifies how much memory should be allocated
+   for the internal compression state.  memLevel=1 uses minimum memory but is
+   slow and reduces compression ratio; memLevel=9 uses maximum memory for
+   optimal speed.  The default value is 8.  See zconf.h for total memory usage
+   as a function of windowBits and memLevel.
+
+     The strategy parameter is used to tune the compression algorithm.  Use the
+   value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a
+   filter (or predictor), Z_HUFFMAN_ONLY to force Huffman encoding only (no
+   string match), or Z_RLE to limit match distances to one (run-length
+   encoding).  Filtered data consists mostly of small values with a somewhat
+   random distribution.  In this case, the compression algorithm is tuned to
+   compress them better.  The effect of Z_FILTERED is to force more Huffman
+   coding and less string matching; it is somewhat intermediate between
+   Z_DEFAULT_STRATEGY and Z_HUFFMAN_ONLY.  Z_RLE is designed to be almost as
+   fast as Z_HUFFMAN_ONLY, but give better compression for PNG image data.  The
+   strategy parameter only affects the compression ratio but not the
+   correctness of the compressed output even if it is not set appropriately.
+   Z_FIXED prevents the use of dynamic Huffman codes, allowing for a simpler
+   decoder for special applications.
+
+     deflateInit2 returns Z_OK if success, Z_MEM_ERROR if there was not enough
+   memory, Z_STREAM_ERROR if any parameter is invalid (such as an invalid
+   method), or Z_VERSION_ERROR if the zlib library version (zlib_version) is
+   incompatible with the version assumed by the caller (ZLIB_VERSION).  msg is
+   set to null if there is no error message.  deflateInit2 does not perform any

+   after the completion of a deflate block, i.e. after all input has been
+   consumed and all output has been delivered when using any of the flush
+   options Z_BLOCK, Z_PARTIAL_FLUSH, Z_SYNC_FLUSH, or Z_FULL_FLUSH.  The
+   compressor and decompressor must use exactly the same dictionary (see
+   inflateSetDictionary).
+
+     The dictionary should consist of strings (byte sequences) that are likely
+   to be encountered later in the data to be compressed, with the most commonly
+   used strings preferably put towards the end of the dictionary.  Using a
+   dictionary is most useful when the data to be compressed is short and can be
+   predicted with good accuracy; the data can then be compressed better than
+   with the default empty dictionary.
+
+     Depending on the size of the compression data structures selected by
+   deflateInit or deflateInit2, a part of the dictionary may in effect be
+   discarded, for example if the dictionary is larger than the window size
+   provided in deflateInit or deflateInit2.  Thus the strings most likely to be
+   useful should be put at the end of the dictionary, not at the front.  In
+   addition, the current implementation of deflate will use at most the window
+   size minus 262 bytes of the provided dictionary.
+
+     Upon return of this function, strm->adler is set to the Adler-32 value
+   of the dictionary; the decompressor may later use this value to determine
+   which dictionary has been used by the compressor.  (The Adler-32 value
+   applies to the whole dictionary even if only a subset of the dictionary is
+   actually used by the compressor.) If a raw deflate was requested, then the

+     inflateBack() does a raw inflate with a single call using a call-back
+   interface for input and output.  This is potentially more efficient than
+   inflate() for file i/o applications, in that it avoids copying between the
+   output and the sliding window by simply making the window itself the output
+   buffer.  inflate() can be faster on modern CPUs when used with large
+   buffers.  inflateBack() trusts the application to not change the output
+   buffer passed by the output function, at least until inflateBack() returns.
+
+     inflateBackInit() must be called first to allocate the internal state
+   and to initialize the state with the user-provided window buffer.
+   inflateBack() may then be used multiple times to inflate a complete, raw
+   deflate stream with each call.  inflateBackEnd() is then called to free the
+   allocated state.
+
+     A raw deflate stream is one with no zlib or gzip header or trailer.
+   This routine would normally be used in a utility that reads zip or gzip
+   files and writes out uncompressed files.  The utility would decode the
+   header and process the trailer on its own, hence this routine expects only
+   the raw deflate stream to decompress.  This is different from the default
+   behavior of inflate(), which expects a zlib header and trailer around the
+   deflate stream.
+
+     inflateBack() uses two subroutines supplied by the caller that are then
+   called by inflateBack() for input and output.  inflateBack() calls those
+   routines until it reads a complete deflate stream and writes out all of the
+   uncompressed data, or until it encounters an error.  The function's
+   parameters and return types are defined above in the in_func and out_func
+   typedefs.  inflateBack() will call in(in_desc, &buf) which should return the
+   number of bytes of provided input, and a pointer to that input in buf.  If
+   there is no input available, in() must return zero -- buf is ignored in that
+   case -- and inflateBack() will return a buffer error.  inflateBack() will
+   call out(out_desc, buf, len) to write the uncompressed data buf[0..len-1].
+   out() should return zero on success, or non-zero on failure.  If out()
+   returns non-zero, inflateBack() will return with an error.  Neither in() nor
+   out() are permitted to change the contents of the window provided to
+   inflateBackInit(), which is also the buffer that out() uses to write from.
+   The length written by out() will be at most the window size.  Any non-zero
+   amount of input may be provided by in().
+
+     For convenience, inflateBack() can be provided input on the first call by
+   setting strm->next_in and strm->avail_in.  If that input is exhausted, then
+   in() will be called.  Therefore strm->next_in must be initialized before
+   calling inflateBack().  If strm->next_in is Z_NULL, then in() will be called
+   immediately for input.  If strm->next_in is not Z_NULL, then strm->avail_in
+   must also be initialized, and then if strm->avail_in is not zero, input will
+   initially be taken from strm->next_in[0 ..  strm->avail_in - 1].
+
+     The in_desc and out_desc parameters of inflateBack() is passed as the
+   first parameter of in() and out() respectively when they are called.  These
+   descriptors can be optionally used to pass any information that the caller-
+   supplied in() and out() functions need to do their job.
+
+     On return, inflateBack() will set strm->next_in and strm->avail_in to
+   pass back any unused input that was provided by the last in() call.  The
+   return values of inflateBack() can be Z_STREAM_END on success, Z_BUF_ERROR
+   if in() or out() returned an error, Z_DATA_ERROR if there was a format error
+   in the deflate stream (in which case strm->msg is set to indicate the nature
+   of the error), or Z_STREAM_ERROR if the stream was not properly initialized.
+   In the case of Z_BUF_ERROR, an input or output error can be distinguished
+   using strm->next_in which will be Z_NULL only if in() returned an error.  If
+   strm->next_in is not Z_NULL, then the Z_BUF_ERROR was due to out() returning
+   non-zero.  (in() will always be called before out(), so strm->next_in is
+   assured to be defined if out() returns non-zero.)  Note that inflateBack()

+# OpenRISC assembly to turn off an ARM core on an Allwinner SoC from
+# the arisc management controller.
+# Generate a binary representation with:
+# $ or1k-elf-as -c -o turn_off_core.o turn_off_core.S
+# $ or1k-elf-objcopy -O binary --reverse-bytes=4 turn_off_core.o \
+#   turn_off_core.bin
+# The encoded instructions go into an array defined in
+# plat/allwinner/sun50i_*/include/core_off_arisc.h, to be handed off to
+# the arisc processor.
+#
+# This routine is meant to be called directly from arisc reset (put the
+# start address in the reset vector), to be actually triggered by that
+# very ARM core to be turned off.
+# It expects the core number presented as a mask in the upper half of
+# r3, so to be patched in the lower 16 bits of the first instruction,
+# overwriting the 0 in this code here.
+# The code will do the following:
+# - Read the C_CPU_STATUS register, which contains the status of the WFI
+#   lines of each of the four A53 cores.
+# - Loop until the core in question reaches WFI.
+# - Using that mask, activate the core output clamps by setting the
+#   respective core bit in CPUX_PWROFF_GATING_REG (0x1f01500).
+#   Note that the clamp for core 0 covers more than just the core, activating
+#   it hangs the whole system. So we skip this step for core 0.
+# - Using the negated mask, assert the core's reset line by clearing the
+#   respective bit in C_RST_CTRL (0x1f01c30).
+# - Finally turn off the core's power switch by writing 0xff to the
+#   respective CPUx_PWR_SWITCH_REG (0x1f01540 ff.)
+# - Assert the arisc's own reset to end execution.
+#   This also signals other arisc users that the chip is free again.
+# So in C this would look like:
+#	while (!(readl(0x1700030) & (1U << core_nr)))
+#		;
+#	if (core_nr != 0)
+#		writel(readl(0x1f01500) | (1U << core_nr), 0x1f01500);
+#	writel(readl(0x1f01c30) & ~(1U << core_nr), 0x1f01c30);
+#	writel(0xff, 0x1f01540 + (core_nr * 4));
+# (using A64/H5 addresses)

+ * The traditional arm64 Linux kernel load address is 512KiB from the
+ * beginning of DRAM, caused by this having been the default value of the
+ * kernel's CONFIG_TEXT_OFFSET Kconfig value.
+ * However kernel version 5.8 changed the default offset (into a 2MB page)
+ * to 0, so TF-A's default assumption is no longer true. Fortunately the
+ * kernel got more relaxed about this offset at the same time, so it
+ * tolerates the wrong offset, but issues a warning:
+ * [Firmware Bug]: Kernel image misaligned at boot, please fix your bootloader!
+ *
+ * We cannot easily change the load address offset in TF-A to be 2MiB, because
+ * this would break older kernels - and they are not as forgiving in this
+ * respect.
+ *
+ * But we can allow users to load the kernel at the right offset, and
+ * offer this trampoline here to transition to this new load address.
+ * Any older kernels, or newer kernels misloaded, will overwrite this code
+ * here, so it does no harm in this case.

+/*
+ * When Poplar is powered on, boot ROM verifies the initial content of
+ * boot media, loads it into low memory, and begins executing it
+ * in 32-bit mode.  The image loaded is "l-loader.bin", which contains
+ * a small amount code along with an embedded ARM Trusted Firmware
+ * BL1 image.  The main purpose of "l-loader" is to prepare the
+ * processor to execute the BL1 image in 64-bit mode, and to trigger
+ * that execution.
+ *
+ * Also embedded in "l-loader.bin" is a FIP image that contains
+ * other ARM Trusted Firmware images:  BL2; BL31; and for BL33,
+ * U-Boot.  When BL1 executes, it unpacks the BL2 image from the FIP
+ * image into a region of memory set aside to hold it.  Similarly,
+ * BL2 unpacks BL31 into memory reserved for it, and unpacks U-Boot
+ * into high memory.
+ *
+ * Because the BL1 code is embedded in "l-loader", its base address
+ * in memory is derived from the base address of the "l-loader"
+ * text section, together with an offset.  Memory space for BL2 is
+ * reserved immediately following BL1, and memory space is reserved
+ * for BL31 after that.  ARM Trusted Firmware requires each of these
+ * memory regions to be aligned on page boundaries, so the size of
+ * each region is a multiple of a page size (ending in 000).  Note
+ * that ARM Trusted Firmware requires the read-only and read-write
+ * regions of memory used for BL1 to be defined separately.

+ * Header file containing the public API for the System Controller (SC)
+ * Pad Control (PAD) function.
+ *
+ * @addtogroup PAD_SVC (SVC) Pad Service
+ *
+ * Module for the Pad Control (PAD) service.
+ *
+ * @details
+ *
+ * Pad configuration is managed by SC firmware. The pad configuration
+ * features supported by the SC firmware include:
+ *
+ * - Configuring the mux, input/output connection, and low-power isolation
+     mode.
+ * - Configuring the technology-specific pad setting such as drive strength,
+ *   pullup/pulldown, etc.
+ * - Configuring compensation for pad groups with dual voltage capability.
+ *
+ * Pad functions fall into one of three categories. Generic functions are
+ * common to all SoCs and all process technologies. SoC functions are raw
+ * low-level functions. Technology-specific functions are specific to the
+ * process technology.
+ *
+ * The list of pads is SoC specific.  Refer to the SoC [Pad List](@ref PADS)
+ * for valid pad values. Note that all pads exist on a die but may or
+ * may not be brought out by the specific package.  Mapping of pads to
+ * package pins/balls is documented in the associated Data Sheet. Some pads
+ * may not be brought out because the part (die+package) is defeatured and
+ * some pads may connect to the substrate in the package.
+ *
+ * Some pads (SC_P_COMP_*) that can be specified are not individual pads
+ * but are in fact pad groups. These groups have additional configuration
+ * that can be done using the sc_pad_set_gp_28fdsoi_comp() function. More
+ * info on these can be found in the associated Reference Manual.
+ *
+ * Pads are managed as a resource by the Resource Manager (RM).  They have
+ * assigned owners and only the owners can configure the pads. Some of the
+ * pads are reserved for use by the SCFW itself and this can be overriden
+ * with the implementation of board_config_sc(). Additionally, pads may
+ * be assigned to various other partitions via the implementation of
+ * board_system_config().
+ *
+ * Note muxing two input pads to the same IP functional signal will
+ * result in undefined behavior.

+	 * pci-aardvark.c which implements access to A3700 PCIe config space.
+	 * Driver does not wait for PCIe PIO transfer completion and try to
+	 * start a new PCIe PIO transfer while previous has not finished yet.
+	 * A3700 PCIe controller in this case sends SLVERR via AXI which results
+	 * in a fatal Asynchronous SError interrupt on Cortex A53 CPU.
+	 *
+	 * Following patches fix that bug in U-Boot and Linux kernel drivers:
+	 * https://source.denx.de/u-boot/u-boot/-/commit/eccbd4ad8e4e182638eafbfb87ac139c04f24a01

+	 * ignore all asynchronous aborts with that syndrome value received on
+	 * CPU from level lower than EL3.
+	 *
+	 * Because these aborts are delivered on CPU asynchronously, they are
+	 * imprecise and we cannot check the real reason of abort and neither
+	 * who and why sent this abort. We expect that on A3700 it is always
+	 * PCIe controller.
+	 *
+	 * Hence ignoring all aborts with this syndrome value is just a giant
+	 * hack that we need only because of bugs in old U-Boot and Linux kernel
+	 * versions and because it was decided that TF-A would implement this
+	 * hack for U-Boot and Linux kernel it in this way. New patched U-Boot
+	 * and kernel versions do not need it anymore.

+ * @freq: which frequency to set.
+ *
+ * For V_VPU0/1, it will only allow 1 of them to modify NPUPLL
+ * such that there will be no race condition happen.
+ *
+ * For V_MDLA0/1, it will only allow 1 of them to modify APUPLL1
+ * such that there will be no race condition happen.
+ *
+ * There are 3 kinds of modes to set pll's rate.
+ * 1. pure sw mode: (CON0_PCW)
+ *        fhctl function is off and change rate by programming CON1_PCW.
+ * 2. fhctl sw mode: (FHCTL_SW)
+ *        fhctl function is on and change rate by programming fhctl_dds.
+ *        (post dividor is still need to program CON1_PCW)
+ * 3. fhctl hw mode: (FHCTL_HW)
+ *        fhctl function is on and change rate by programming fhctl_dvfs.
+ *        (post dividor is still need to program CON1_PCW)
+ *
+ * Context: Any context.
+ * Return:
+ * * 0 - done for set rate of voltage domain.

+/**
+ * init_pmu_counts - Init timing counts in the PMU register area
+ *
+ * At various points when we power up or down parts of the system we need
+ * a delay to wait for power / clocks to become stable.  The PMU has counters
+ * to help software do the delay properly.  Basically, it works like this:
+ * - Software sets up counter values
+ * - When software turns on something in the PMU, the counter kicks off
+ * - The hardware sets a bit automatically when the counter has finished and
+ *   software knows that the initialization is done.
+ *
+ * It's software's job to setup these counters.  The hardware power on default
+ * for these settings is conservative, setting everything to 0x5dc0
+ * (750 ms in 32 kHz counts or 1 ms in 24 MHz counts).
+ *
+ * Note that some of these counters are only really used at suspend/resume
+ * time (for instance, that's the only time we turn off/on the oscillator) and
+ * others are used during normal runtime (like turning on/off a CPU or GPU) but
+ * it doesn't hurt to init everything at boot.
+ *
+ * Also note that these counters can run off the 32 kHz clock or the 24 MHz
+ * clock.  While the 24 MHz clock can give us more precision, it's not always
+ * available (like when we turn the oscillator off at sleep time). The
+ * pmu_use_lf (lf: low freq) is available in power mode.  Current understanding
+ * is that counts work like this:
+ *    IF (pmu_use_lf == 0) || (power_mode_en == 0)
+ *      use the 24M OSC for counts
+ *    ELSE
+ *      use the 32K OSC for counts
+ *
+ * Notes:
+ * - There is a separate bit for the PMU called PMU_24M_EN_CFG.  At the moment
+ *   we always keep that 0.  This apparently choose between using the PLL as
+ *   the source for the PMU vs. the 24M clock.  If we ever set it to 1 we
+ *   should consider how it affects these counts (if at all).
+ * - The power_mode_en is documented to auto-clear automatically when we leave
+ *   "power mode".  That's why most clocks are on 24M.  Only timings used when
+ *   in "power mode" are 32k.
+ * - In some cases the kernel may override these counts.
+ *
+ * The PMU_STABLE_CNT / PMU_OSC_CNT / PMU_PLLLOCK_CNT are important CNTs
+ * in power mode, we need to ensure that they are available.

+Trusted Firmware-A
+==================
+
+Trusted Firmware-A (TF-A) is a reference implementation of secure world software
+for `Arm A-Profile architectures`_ (Armv8-A and Armv7-A), including an Exception
+Level 3 (EL3) `Secure Monitor`_. It provides a suitable starting point for
+productization of secure world boot and runtime firmware, in either the AArch32
+or AArch64 execution states.
+
+TF-A implements Arm interface standards, including:
+
+-  `Power State Coordination Interface (PSCI)`_
+-  `Trusted Board Boot Requirements CLIENT (TBBR-CLIENT)`_
+-  `SMC Calling Convention`_
+-  `System Control and Management Interface (SCMI)`_
+-  `Software Delegated Exception Interface (SDEI)`_
+
+The code is designed to be portable and reusable across hardware platforms and
+software models that are based on the Armv8-A and Armv7-A architectures.
+
+In collaboration with interested parties, we will continue to enhance TF-A
+with reference implementations of Arm standards to benefit developers working
+with Armv7-A and Armv8-A TrustZone technology.
+
+Users are encouraged to do their own security validation, including penetration
+testing, on any secure world code derived from TF-A.
+
+More Info and Documentation
+---------------------------
+
+To find out more about Trusted Firmware-A, please `view the full documentation`_
+that is available through `trustedfirmware.org`_.

+Description:
+------------
+Tool 'create_pbl' is a standalone tool to create the PBL images.
+	 where,
+	     On the basis of Chassis,
+	     RCW image is placed first followed by the,
+	     PBI commands to copy the,
+	     Input BL2 image stored on the,
+	     Specified boot source (QSPI or SD or NOR) to the,
+             Specified destination address.
+
+
+Usage in standalone way:
+-----------------------
+
+./create_pbl [options] (mentioned below):
+
+	-r  <RCW file-name>         - name of RCW binary file.
+	-i  <BL2 Bin file-name>     - file to be added to rcw file.
+	-c  <SoC Number>            - SoC numeric identifier, may be one of
+                                  1012,1023,1026.1028,
+                                  1043,1046,1088,2080,
+                                  2088,2160
+	-b  <boot source id>        - Boot source id string, may be one of
+                                  "qspi", "nor", "nand", "sd", "emmc"
+	-d  <Address>               - Destination address where BL2
+	                              image is to be copied
+	-o  <output filename>	    - Name of PBL image generated
+	                              as an output of the tool.
+	-e  <Address>               - [Optional] Entry Point Address
+	                              of the BL2.bin
+	-f  <Address>               - BL2 image offset
+	                              on Boot Source for block copy.
+	                              command for chassis >=3.)
+				      (Must for Ch3, Ignored for Ch2)
+	-h  Help.
+	-s  Secure boot.
+
+		-s 	secure boot
+		-c	SoC Number (see description above)
+		-b	Boot source.
+		-r	RCW binary file.
+		-i	Input file that is to be added to rcw file.
+		-o	Name of output file
+		-f	Source Offset (Block Copy)
+		-d	Destination address to which file has to be copied
+		-h	Help.
+
+Example:
+	./create_pbl -r <RCW file> -i <bl2.bin> -c <chassis_no> -b <boot_source = sd/qspi/nor> -d <Destination_Addr> -o <pbl_image_name>
+
+
+
+Usage at compilation time:
+--------------------------------
+
+	make <compilation command......> pbl RCW=<Path_to_RCW_File>/<rcw_file_name.bin>
+
+Example: QSPI Boot For LS1046ARDB-
+
+	make PLAT=ls1046rdb all fip BOOT_MODE=qspi SPD=opteed BL32=tee.bin BL33=u-boot-ls1046.bin pbl RCW=/home/pankaj/flexbuild/packages/firmware/dash-rcw/ls1046ardb/RR_FFSSPPPN_1133_5506/rcw_1600_qspiboot.bin
+
+Example: QSPI Boot For LX2160ARDB-
+
+	make PLAT=lx2160ardb all fip BOOT_MODE=flexspi_nor SPD=opteed BL32=tee_lx2.bin BL33=u-boot_lx2160.bin pbl RCW=plat/nxp/soc-lx2160/lx2160ardb/rcw_1900_600_1600_19_5_2.bin

+This script is invoked by Make system and generates secure partition makefile.
+It expects platform provided secure partition layout file which contains list
+of Secure Partition Images and Partition manifests(PM).
+Layout file can exist outside of TF-A tree and the paths of Image and PM files
+must be relative to it.
+
+This script parses the layout file and generates a make file which updates
+FDT_SOURCES, FIP_ARGS, CRT_ARGS and SPTOOL_ARGS which are used in later build
+steps.
+If the SP entry in the layout file has a "uuid" field the scripts gets the UUID
+from there, otherwise it parses the associated partition manifest and extracts
+the UUID from there.
+
+param1: Generated mk file "sp_gen.mk"
+param2: "SP_LAYOUT_FILE", json file containing platform provided information
+param3: plat out directory
+param4: CoT parameter
+
+Generated "sp_gen.mk" file contains triplet of following information for each
+Secure Partition entry
+    FDT_SOURCES +=  sp1.dts
+    SPTOOL_ARGS += -i sp1.bin:sp1.dtb -o sp1.pkg
+    FIP_ARGS += --blob uuid=XXXXX-XXX...,file=sp1.pkg
+    CRT_ARGS += --sp-pkg1 sp1.pkg
+
+A typical SP_LAYOUT_FILE file will look like
+{
+        "SP1" : {
+                "image": "sp1.bin",
+                "pm": "test/sp1.dts"

+This is a python module for defining and executing SP setup actions, targeting
+a system deploying an SPM implementation.
+Each action consists of a function, that processes the SP layout json file and
+other provided arguments.
+At the core of this is the SpSetupActions which provides a means to register
+the functions into a table of actions, and execute them all when invoking
+SpSetupActions.run_actions.
+Registering the function is done by using the decorator '@SpSetupActions.sp_action'
+at function definition.
+
+Functions can be called:
+- once only, or per SP defined in the SP layout file;
+- following an order, from lowest to highest of their execution order.
+More information in the doc comments below.
