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
