I've started trying to hack up test_efi_loader.py to add a test that loads OpenBSD's bootloader.. kinda muddling through it at this point, since not a py expert or too familiar w/ u-boot's test framework. But I'll see if I can get to the point where I can run the same thing on various arm7 and aarch64 devices in qemu.
Making a bit of progress on this (running it on a vexpress_ca15_tc2 board in qemu).. any hint where I can find BOOTARM.EFI src code?

Your failure below looks a bit different from what I'm getting on the Banana Pi now. There I get stuck because the 2nd BS->HandleProtocol() call in efi_main() fails. Somehow the device path of the registered disk devices isn't matched correctly to the boot device path...
BTW, the OpenBSD code runs fine without the alignment hack. Our code is pretty minimal and doesn't actualy look into the device path components. It just matches the components based on type and by soing memcmp.
