config EFI_LOADER bool "Support running EFI Applications in U-Boot" depends on (ARM || X86 || RISCV || SANDBOX) && OF_LIBFDT # We need EFI_STUB_64BIT to be set on x86_64 with EFI_STUB depends on !EFI_STUB || !X86_64 || EFI_STUB_64BIT # We need EFI_STUB_32BIT to be set on x86_32 with EFI_STUB depends on !EFI_STUB || !X86 || X86_64 || EFI_STUB_32BIT default y select LIB_UUID select HAVE_BLOCK_DEVICE select REGEX imply CFB_CONSOLE_ANSI help Select this option if you want to run EFI applications (like grub2) on top of U-Boot. If this option is enabled, U-Boot will expose EFI interfaces to a loaded EFI application, enabling it to reuse U-Boot's device drivers. config EFI_UNICODE_CAPITALIZATION bool "Support Unicode capitalization" depends on EFI_LOADER 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 EFI_LOADER && 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_LOADER_HII bool "Expose HII protocols to EFI applications" depends on EFI_LOADER default n 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. The code is experimental still, so beware that your system might break with HII enabled. If unsure, say n.
