config ARM_SCMI_PROTOCOL
	bool "ARM System Control and Management Interface (SCMI) Message Protocol"
	depends on ARM || ARM64 || COMPILE_TEST
	depends on MAILBOX
	help
	  ARM System Control and Management Interface (SCMI) protocol is a
	  set of operating system-independent software interfaces that are
	  used in system management. SCMI is extensible and currently provides
	  interfaces for: Discovery and self-description of the interfaces
	  it supports, Power domain management which is the ability to place
	  a given device or domain into the various power-saving states that
	  it supports, Performance management which is the ability to control
	  the performance of a domain that is composed of compute engines
	  such as application processors and other accelerators, Clock
	  management which is the ability to set and inquire rates on platform
	  managed clocks and Sensor management which is the ability to read
	  sensor data, and be notified of sensor value.

	  This protocol library provides interface for all the client drivers
	  making use of the features offered by the SCMI.

	  communication and also exposes the ops used by clients.

config QTI_SCMI_PLH_PROTOCOL
	tristate "Qualcomm Technologies, Inc. SCMI PLH vendor Protocol"
	depends on ARM_SCMI_PROTOCOL && QCOM_RIMPS && QGKI
	help
	  System Control and Management Interface (SCMI) plh vendor protocol
	  this protocol provides interface to communicate with micro controller
	  which is executing the plh algorithm

	  This driver defines the comands or message ID's used for this
	  communication and also exposes the ops used by clients.

	tristate "SCMI power domain driver"
	depends on ARM_SCMI_PROTOCOL || (COMPILE_TEST && OF)
	default y
	select PM_GENERIC_DOMAINS if PM
	help
	  This enables support for the SCMI power domains which can be
	  enabled or disabled via the SCP firmware

	  This driver can also be built as a module.  If so, the module
	  will be called scmi_pm_domain. Note this may needed early in boot
	  before rootfs may be available.

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 managament 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.

	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/>

	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

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.

	  may crash your system.

config INTEL_STRATIX10_SERVICE
	tristate "Intel Stratix10 Service Layer"
	depends on ARCH_STRATIX10 && 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)

	  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

	  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.
