I could successfully install build and flash the uboot with uefi over minnowboard (from Intel) and could use a serial console to see the prints.

We tried running LUV test and SCT test, but both failed.
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: https://patchwork.ozlabs.org/patch/812655/ spl: u-boot-spl-nodtb.bin: remove .got and .got.plt sections
