In qemu-system-x86 I am able to load 32 bit GRUB via EFI but never succeeded to
boot Linux. Linux used the video memory. And of cause video memory is
overwritten by console output.
Part of a solution might be unmerged patch
https://patchwork.ozlabs.org/patch/860400/
efi_loader: memory reservations according to e820 table but this patch needs
rework as indicated by Alex.
On x86_64 an implementation of setjmp() and longjmp() is missing. These are
necessary to use the Exit() boot service or to directly return from an EFI
binary.
On Debian building for x86_64 fails without this rejected patch:

spl: u-boot-spl-nodtb.bin: remove .got and .got.plt sections
Best regards
