+This section lists the supported Arm |FVP| platforms. Please refer to the FVP
+documentation for a detailed description of the model parameter options.
+
+The latest version of the AArch64 build of TF-A has been tested on the following
+Arm FVPs without shifted affinities, and that do not support threaded CPU cores
+(64-bit host machine only).

+
+.. note::
+ The ``FVP_Base_RevC-2xAEMvA`` FVP only supports shifted affinities, which
+ is not compatible with legacy GIC configurations. Therefore this FVP does not
+ 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
+ the models. The models can be launched with ``-Q 100`` option if they are
+ required to match the run time characteristics of the older versions.
+
+All the above platforms have been tested with `Linaro Release 20.01`_.

+
+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:
+
+::
+
+ --data cluster0.cpu0=mailbox.dat@0x04000000 [Base FVPs]
+ --data=mailbox.dat@0x04000000 [Foundation FVP]
+
+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
+
+ <path-to>/FVP_Base_AEMv8A-AEMv8A \
+ -C pctl.startup=0.0.0.0 \
+ -C bp.secure_memory=1 \
+ -C cluster0.NUM_CORES=4 \
+ -C cluster1.NUM_CORES=4 \
+ -C cache_state_modelled=1 \
+ -C cluster0.cpu0.RVBAR=0x04001000 \
+ -C cluster0.cpu1.RVBAR=0x04001000 \
+ -C cluster0.cpu2.RVBAR=0x04001000 \
+ -C cluster0.cpu3.RVBAR=0x04001000 \
+ -C cluster1.cpu0.RVBAR=0x04001000 \
+ -C cluster1.cpu1.RVBAR=0x04001000 \
+ -C cluster1.cpu2.RVBAR=0x04001000 \
+ -C cluster1.cpu3.RVBAR=0x04001000 \
+ --data cluster0.cpu0="<path-to>/bl31.bin"@0x04001000 \
+ --data cluster0.cpu0="<path-to>/<patched-fdt>"@0x82000000 \
+ --data cluster0.cpu0="<path-to>/<kernel-binary>"@0x80080000 \
+ --data cluster0.cpu0="<path-to>/<ramdisk.img>"@0x84000000
+
+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).
+
+- ``fvp-base-gicv2-psci.dts``

+ For use with models such as the Cortex-A57-A53 or Cortex-A32 Base FVPs
+ without shifted affinities and with Base memory map configuration.
+

+
+ For use with models such as the Cortex-A57-A53 or Cortex-A32 Base FVPs

+
+
+Running on the Foundation FVP with reset to BL1 entrypoint
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The following ``Foundation_Platform`` parameters should be used to boot Linux with
+4 CPUs using the AArch64 build of TF-A.
+
+.. code:: shell
+
+ <path-to>/Foundation_Platform \
+ --cores=4 \
+ --arm-v8.0 \
+ --secure-memory \
+ --visualization \
+ --gicv3 \
+ --data="<path-to>/<bl1-binary>"@0x0 \
+ --data="<path-to>/<FIP-binary>"@0x08000000 \
+ --data="<path-to>/<kernel-binary>"@0x80080000 \
+ --data="<path-to>/<ramdisk-binary>"@0x84000000
+
+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
+ Payload. For the same reason, the FDT needs to be compiled from the DT source
+ and loaded via the ``--data cluster0.cpu0="<path-to>/<fdt>"@0x82000000``
+ parameter.
+
+- The ``FVP_Base_RevC-2xAEMv8A`` has shifted affinities and requires a
+ specific DTS for all the CPUs to be loaded.
+
+- The ``-C cluster<X>.cpu<Y>.RVBAR=@<base-address-of-bl31>`` parameter, where
+ X and Y are the cluster and CPU numbers respectively, is used to set the
+ reset vector for each core.
+
+- Changing the default value of ``ARM_TSP_RAM_LOCATION`` will also require
+ changing the value of
+ ``--data="<path-to><bl32-binary>"@<base-address-of-bl32>`` to the new value of
+ ``BL32_BASE``.
