2 bool "Support running EFI Applications in U-Boot"
3 depends on (ARM || X86 || RISCV || SANDBOX) && OF_LIBFDT
4 # We need EFI_STUB_64BIT to be set on x86_64 with EFI_STUB
5 depends on !EFI_STUB || !X86_64 || EFI_STUB_64BIT
6 # We need EFI_STUB_32BIT to be set on x86_32 with EFI_STUB
7 depends on !EFI_STUB || !X86 || X86_64 || EFI_STUB_32BIT
10 select HAVE_BLOCK_DEVICE
12 imply CFB_CONSOLE_ANSI
14 Select this option if you want to run EFI applications (like grub2)
15 on top of U-Boot. If this option is enabled, U-Boot will expose EFI
16 interfaces to a loaded EFI application, enabling it to reuse U-Boot's
19 config EFI_UNICODE_CAPITALIZATION
20 bool "Support Unicode capitalization"
24 Select this option to enable correct handling of the capitalization of
25 Unicode codepoints in the range 0x0000-0xffff. If this option is not
26 set, only the the correct handling of the letters of the codepage
27 used by the FAT file system is ensured.
29 config EFI_LOADER_BOUNCE_BUFFER
30 bool "EFI Applications use bounce buffers for DMA operations"
31 depends on EFI_LOADER && ARM64
34 Some hardware does not support DMA to full 64bit addresses. For this
35 hardware we can create a bounce buffer so that payloads don't have to
36 worry about platform details.
39 bool "Expose HII protocols to EFI applications"
43 The Human Interface Infrastructure is a complicated framework that
44 allows UEFI applications to draw fancy menus and hook strings using
45 a translation framework.
47 U-Boot implements enough of its features to be able to run the UEFI
48 Shell, but not more than that.
