+config ARM_SCPI_PROTOCOL
+ tristate "ARM System Control and Power Interface (SCPI) Message Protocol"
+ depends on ARM || ARM64 || COMPILE_TEST
+ depends on MAILBOX
+ help
+ System Control and Power Interface (SCPI) Message Protocol is
+ defined for the purpose of communication between the Application
+ Cores(AP) and the System Control Processor(SCP). The MHU peripheral
+ provides a mechanism for inter-processor communication between SCP
+ and AP.
+
+ SCP controls most of the power management on the Application
+ Processors. It offers control and management of: the core/cluster
+ power states, various power domain DVFS including the core/cluster,
+ certain system clocks configuration, thermal sensors and many
+ others.
+
+ This protocol library provides interface for all the client drivers
+ making use of the features offered by the SCP.
+
+config ARM_SCPI_POWER_DOMAIN
+ tristate "SCPI power domain driver"
+ depends on ARM_SCPI_PROTOCOL || (COMPILE_TEST && OF)
+ default y
+ select PM_GENERIC_DOMAINS if PM
+ help
+ This enables support for the SCPI power domains which can be
+ enabled or disabled via the SCP firmware
+
+config ARM_SDE_INTERFACE
+ bool "ARM Software Delegated Exception Interface (SDEI)"
+ depends on ARM64
+ depends on ACPI_APEI_GHES
+ help
+ The Software Delegated Exception Interface (SDEI) is an ARM
+ standard for registering callbacks from the platform firmware
+ into the OS. This is typically used to implement RAS notifications.
+
+config EDD
+ tristate "BIOS Enhanced Disk Drive calls determine boot disk"
+ depends on X86
+ help
+ Say Y or M here if you want to enable BIOS Enhanced Disk Drive
+ Services real mode BIOS calls to determine which disk
+ BIOS tries boot from. This information is then exported via sysfs.
+
+ This option is experimental and is known to fail to boot on some
+ obscure configurations. Most disk controller BIOS vendors do
+ not yet implement this feature.
+
+config EDD_OFF
+ bool "Sets default behavior for EDD detection to off"
+ depends on EDD
+ default n
+ help
+ Say Y if you want EDD disabled by default, even though it is compiled into the
+ kernel. Say N if you want EDD enabled by default. EDD can be dynamically set
+ using the kernel parameter 'edd={on|skipmbr|off}'.
+
+config FIRMWARE_MEMMAP
+ bool "Add firmware-provided memory map to sysfs" if EXPERT
+ default X86
+ help
+ Add the firmware-provided (unmodified) memory map to /sys/firmware/memmap.
+ That memory map is used for example by kexec to set up parameter area
+ for the next kernel, but can also be used for debugging purposes.
+
+ See also Documentation/ABI/testing/sysfs-firmware-memmap.
+
+config EFI_PCDP
+ bool "Console device selection via EFI PCDP or HCDP table"
+ depends on ACPI && EFI && IA64
+ default y if IA64
+ help
+ If your firmware supplies the PCDP table, and you want to
+ automatically use the primary console device it describes
+ as the Linux console, say Y here.
+
+ If your firmware supplies the HCDP table, and you want to
+ use the first serial port it describes as the Linux console,
+ say Y here. If your EFI ConOut path contains only a UART
+ device, it will become the console automatically. Otherwise,
+ you must specify the "console=hcdp" kernel boot argument.
+
+ Neither the PCDP nor the HCDP affects naming of serial devices,
+ so a serial console may be /dev/ttyS0, /dev/ttyS1, etc, depending
+ on how the driver discovers devices.
+
+ You must also enable the appropriate drivers (serial, VGA, etc.)
+
+ See DIG64_HCDPv20_042804.pdf available from
+ <http://www.dig64.org/specifications/>
+
+config DMIID
+ bool "Export DMI identification via sysfs to userspace"
+ depends on DMI
+ default y
+ help
+ Say Y here if you want to query SMBIOS/DMI system identification
+ information from userspace through /sys/class/dmi/id/ or if you want
+ DMI-based module auto-loading.
+
+config DMI_SYSFS
+ tristate "DMI table support in sysfs"
+ depends on SYSFS && DMI
+ default n
+ help
+ Say Y or M here to enable the exporting of the raw DMI table
+ data via sysfs. This is useful for consuming the data without
+ requiring any access to /dev/mem at all. Tables are found
+ under /sys/firmware/dmi when this option is enabled and
+ loaded.
+
+config DMI_SCAN_MACHINE_NON_EFI_FALLBACK
+ bool
+
+config ISCSI_IBFT_FIND
+ bool "iSCSI Boot Firmware Table Attributes"
+ depends on X86 && ISCSI_IBFT
+ default n
+ help
+ This option enables the kernel to find the region of memory
+ in which the ISCSI Boot Firmware Table (iBFT) resides. This
+ is necessary for iSCSI Boot Firmware Table Attributes module to work
+ properly.
+
+config ISCSI_IBFT
+ tristate "iSCSI Boot Firmware Table Attributes module"
+ select ISCSI_BOOT_SYSFS
+ select ISCSI_IBFT_FIND if X86
+ depends on ACPI && SCSI && SCSI_LOWLEVEL
+ default n
+ help
+ This option enables support for detection and exposing of iSCSI
+ Boot Firmware Table (iBFT) via sysfs to userspace. If you wish to
+ detect iSCSI boot parameters dynamically during system boot, say Y.
+ Otherwise, say N.
+
+config RASPBERRYPI_FIRMWARE
+ tristate "Raspberry Pi Firmware Driver"
+ depends on BCM2835_MBOX
+ help
+ This option enables support for communicating with the firmware on the
+ Raspberry Pi.
+
+config FW_CFG_SYSFS
+ tristate "QEMU fw_cfg device support in sysfs"
+ depends on SYSFS && (ARM || ARM64 || PARISC || PPC_PMAC || SPARC || X86)
+ depends on HAS_IOPORT_MAP
+ default n
+ help
+ Say Y or M here to enable the exporting of the QEMU firmware
+ configuration (fw_cfg) file entries via sysfs. Entries are
+ found under /sys/firmware/fw_cfg when this option is enabled
+ and loaded.
+
+config FW_CFG_SYSFS_CMDLINE
+ bool "QEMU fw_cfg device parameter parsing"
+ depends on FW_CFG_SYSFS
+ help
+ Allow the qemu_fw_cfg device to be initialized via the kernel
+ command line or using a module parameter.
+ WARNING: Using incorrect parameters (base address in particular)
+ may crash your system.
+
+config INTEL_STRATIX10_SERVICE
+ tristate "Intel Stratix10 Service Layer"
+ depends on ARCH_INTEL_SOCFPGA && ARM64 && HAVE_ARM_SMCCC
+ default n
+ help
+ Intel Stratix10 service layer runs at privileged exception level,
+ interfaces with the service providers (FPGA manager is one of them)
+ and manages secure monitor call to communicate with secure monitor
+ software at secure monitor exception level.
+
+ Say Y here if you want Stratix10 service layer support.
+
+config INTEL_STRATIX10_RSU
+ tristate "Intel Stratix10 Remote System Update"
+ depends on INTEL_STRATIX10_SERVICE
+ help
+ The Intel Remote System Update (RSU) driver exposes interfaces
+ access through the Intel Service Layer to user space via sysfs
+ device attribute nodes. The RSU interfaces report/control some of
+ the optional RSU features of the Stratix 10 SoC FPGA.
+
+ The RSU provides a way for customers to update the boot
+ configuration of a Stratix 10 SoC device with significantly reduced
+ risk of corrupting the bitstream storage and bricking the system.
+
+ Enable RSU support if you are using an Intel SoC FPGA with the RSU
+ feature enabled and you want Linux user space control.
+
+ Say Y here if you want Intel RSU support.
+
+config MTK_ADSP_IPC
+ tristate "MTK ADSP IPC Protocol driver"
+ depends on MTK_ADSP_MBOX
+ help
+ Say yes here to add support for the MediaTek ADSP IPC
+ between host AP (Linux) and the firmware running on ADSP.
+ ADSP exists on some mtk processors.
+ Client might use shared memory to exchange information with ADSP.
+
+config QCOM_SCM
+ tristate
+
+config QCOM_SCM_DOWNLOAD_MODE_DEFAULT
+ bool "Qualcomm download mode enabled by default"
+ depends on QCOM_SCM
+ help
+ A device with "download mode" enabled will upon an unexpected
+ warm-restart enter a special debug mode that allows the user to
+ "download" memory content over USB for offline postmortem analysis.
+ The feature can be enabled/disabled on the kernel command line.
+
+ Say Y here to enable "download mode" by default.
+
+config SYSFB
+ bool
+ select BOOT_VESA_SUPPORT
+
+config SYSFB_SIMPLEFB
+ bool "Mark VGA/VBE/EFI FB as generic system framebuffer"
+ depends on X86 || EFI
+ select SYSFB
+ help
+ Firmwares often provide initial graphics framebuffers so the BIOS,
+ bootloader or kernel can show basic video-output during boot for
+ user-guidance and debugging. Historically, x86 used the VESA BIOS
+ Extensions and EFI-framebuffers for this, which are mostly limited
+ to x86 BIOS or EFI systems.
+ This option, if enabled, marks VGA/VBE/EFI framebuffers as generic
+ framebuffers so the new generic system-framebuffer drivers can be
+ used instead. If the framebuffer is not compatible with the generic
+ modes, it is advertised as fallback platform framebuffer so legacy
+ drivers like efifb, vesafb and uvesafb can pick it up.
+ If this option is not selected, all system framebuffers are always
+ marked as fallback platform framebuffers as usual.
+
+ Note: Legacy fbdev drivers, including vesafb, efifb, uvesafb, will
+ not be able to pick up generic system framebuffers if this option
+ is selected. You are highly encouraged to enable simplefb as
+ replacement if you select this option. simplefb can correctly deal
+ with generic system framebuffers. But you should still keep vesafb
+ and others enabled as fallback if a system framebuffer is
+ incompatible with simplefb.
+
+ If unsure, say Y.
+
+config TI_SCI_PROTOCOL
+ tristate "TI System Control Interface (TISCI) Message Protocol"
+ depends on TI_MESSAGE_MANAGER
+ help
+ TI System Control Interface (TISCI) Message Protocol is used to manage
+ compute systems such as ARM, DSP etc with the system controller in
+ complex System on Chip(SoC) such as those found on certain keystone
+ generation SoC from TI.
+
+ System controller provides various facilities including power
+ management function support.
+
+ This protocol library is used by client drivers to use the features
+ provided by the system controller.
+
+config TRUSTED_FOUNDATIONS
+ bool "Trusted Foundations secure monitor support"
+ depends on ARM && CPU_V7
+ help
+ Some devices (including most early Tegra-based consumer devices on
+ the market) are booted with the Trusted Foundations secure monitor
+ active, requiring some core operations to be performed by the secure
+ monitor instead of the kernel.
+
+ This option allows the kernel to invoke the secure monitor whenever
+ required on devices using Trusted Foundations. See the functions and
+ comments in linux/firmware/trusted_foundations.h or the device tree
+ bindings for "tlm,trusted-foundations" for details on how to use it.
+
+ Choose N if you don't know what this is about.
+
+config TURRIS_MOX_RWTM
+ tristate "Turris Mox rWTM secure firmware driver"
+ depends on ARCH_MVEBU || COMPILE_TEST
+ depends on HAS_DMA && OF
+ depends on MAILBOX
+ select HW_RANDOM
+ select ARMADA_37XX_RWTM_MBOX
+ help
+ This driver communicates with the firmware on the Cortex-M3 secure
+ processor of the Turris Mox router. Enable if you are building for
+ Turris Mox, and you will be able to read the device serial number and
+ other manufacturing data and also utilize the Entropy Bit Generator
+ for hardware random number generation.
