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?
There is some kind of hard hang on OpenBSD with vexpress at the moment and there is no driver for the sd/mmc but getting to that point seemed quite a bit more painful than using U-Boot on real hardware.
