Yes, either Grub with menu, or the simple U-Boot device selection would work.
People doing testing could then select which OS to boot. If it fails, no problem,
just reboot and select the working OS and make a change to the one under
test. Then try again.
At present, I don't see Grub getting both text menu, (on the LCD), and keyboard
support, (also the PBP keyboard, not serial console), any time soon. Grub seems
to support such for x86/x64, but that is likely through BIOS calls that don't exist
for any ARM computer.
Thinking about it, I've added ESC & Return keys to the original post, to do the
obvious thing.
