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?

Why does U-Boot not set fdt_addr_r or fdtfile for vexpress? Worse yet trying to load to the default kernel_addr_r fails. So it requires a script or manual commands to boot instead of the usual distro boot arrangement?
I suspect this is specific to the test framework (probably not enabling distro-boot-cmd so that the test framework can run the cmds it wants??)
I didn't attempt to use the test framework, just loaded the result of building vexpress_ca15_tc2_defconfig into qemu.
It looks like the load addresses are only good for >= 1G physmem.
