	help
	  Select this option if you want to run UEFI applications (like GNU
	  GRUB or iPXE) on top of U-Boot. If this option is enabled, U-Boot
	  will expose the UEFI API to a loaded application, enabling it to
	  reuse U-Boot's device drivers.

config EFI_DEVICE_PATH_TO_TEXT
	bool "Device path to text protocol"
	default y
	help
	  The device path to text protocol converts device nodes and paths to
	  human readable strings.

config EFI_LOADER_HII
	bool "HII protocols"
	default y
	help
	  The Human Interface Infrastructure is a complicated framework that
	  allows UEFI applications to draw fancy menus and hook strings using
	  a translation framework.

	  U-Boot implements enough of its features to be able to run the UEFI
	  Shell, but not more than that.

config EFI_UNICODE_COLLATION_PROTOCOL
	bool "Unicode collation protocol"
	default y
	help
	  The Unicode collation protocol is used for lexical comparisons. It is
	  required to run the UEFI shell.

if EFI_UNICODE_COLLATION_PROTOCOL

config EFI_UNICODE_CAPITALIZATION
	bool "Support Unicode capitalization"
	default y
	help
	  Select this option to enable correct handling of the capitalization of
	  Unicode codepoints in the range 0x0000-0xffff. If this option is not
	  set, only the the correct handling of the letters of the codepage
	  used by the FAT file system is ensured.

config EFI_LOADER_BOUNCE_BUFFER
	bool "EFI Applications use bounce buffers for DMA operations"
	depends on ARM64
	default n
	help
	  Some hardware does not support DMA to full 64bit addresses. For this
	  hardware we can create a bounce buffer so that payloads don't have to
	  worry about platform details.

config EFI_PLATFORM_LANG_CODES
	string "Language codes supported by firmware"
	default "en-US"
	help
	  This value is used to initialize the PlatformLangCodes variable. Its
	  value is a semicolon (;) separated list of language codes in native
	  RFC 4646 format, e.g. "en-US;de-DE". The first language code is used
	  to initialize the PlatformLang variable.
