	tristate "EFI Variable Support via sysfs"
	depends on EFI
	default n
	help
	  If you say Y here, you are able to get EFI (Extensible Firmware
	  Interface) variable information via sysfs.  You may read,
	  write, create, and destroy EFI variables through this interface.

	  Note that using this driver in concert with efibootmgr requires
	  at least test release version 0.5.0-test3 or later, which is
	  available from Matt Domsch's website located at:
	  <http://linux.dell.com/efibootmgr/testing/efibootmgr-0.5.0-test3.tar.gz>

	  Subsequent efibootmgr releases may be found at:

	depends on EFI_VARS && PSTORE
	default y
	help
	  Say Y here to enable use efivars as a backend to pstore. This
	  will allow writing console messages, crash dumps, or anything
	  else supported by pstore to EFI variables.

config EFI_VARS_PSTORE_DEFAULT_DISABLE
	bool "Disable using efivars as a pstore backend by default"
	depends on EFI_VARS_PSTORE
	default n
	help
	  Saying Y here will disable the use of efivars as a storage
	  backend for pstore by default. This setting can be overridden
	  using the efivars module's pstore_disable parameter.

config EFI_RUNTIME_MAP
	bool "Export efi runtime maps to sysfs"
	depends on X86 && EFI && KEXEC
	default y
	help
	  Export efi runtime memory maps to /sys/firmware/efi/runtime-map.
	  That memory map is used for example by kexec to set up efi virtual
	  mapping the 2nd kernel, but can also be used for debugging purposes.

	  See also Documentation/ABI/testing/sysfs-firmware-efi-runtime-map.

config EFI_PARAMS_FROM_FDT
	bool
	help
	  Select this config option from the architecture Kconfig if
	  the EFI runtime support gets system table address, memory
          map address, and other parameters from the device tree.
