Enable this so that EFI applications (notably grub) can be run under U-Boot on x86 platforms. At present the 'hello world' EFI application is not supported for the qemu-x86_efi_payload64 board. That board builds a payload consisting of a 64-bit header and a 32-bit U-Boot, which is incompatible with the way the EFI loader builds its EFI application. The following error is obtained: x86_64-linux-ld.bfd: i386 architecture of input file `lib/efi_loader/helloworld.o' is incompatible with i386:x86-64 output This could be corrected with additional Makefile rules. For now, this feature is disabled for that board.

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.

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.
