Trying to compile an x86_64 u-boot with EFI support:

with the attached configuration. Am I doing it wrong?
I don't have the environment to test but did you use efi-x86_defconfig?
No, the config I attached has been edited because when I use efi-x86_defconfig I get a mix of 32-bit and 64-bit objects:
/home/jer/airfi/airfi-base/apollo/output/host/usr/bin/x86_64-buildroot-linux-gnu-ld.bfd: Relocatable linking with relocations from format elf32-i386 (board/efi/efi-x86/efi.o) to format elf64-x86-64 (board/efi/efi-x86/built-in.o) is not supported make[2]: *** [scripts/Makefile.build:359: board/efi/efi-x86/built-in.o] Error 1 make[1]: *** [Makefile:1234: board/efi/efi-x86] Error 2 make[1]: *** Waiting for unfinished jobs....
So I needed to adapt it for a 64-bit target by enabling CONFIG_X86_RUN_64BIT
CONFIG_X86_RUN_64BIT is supposed to be turned on a 64-bit U-Boot build, not for EFI application.
