This is not true. For those boards, we can still use EFI, but need to
convert to MBR. This is done in uboot-image-install.in in section
"Convert GPT to MBR if necessary".

The only case I'm aware of where EFI is not a viable option is when we
rely on U-Boot that is delivered with the system, but doesn't have
efi_loader enablement. Apart from moonshot and midway I'm not aware of
any such system still alive.

That should also work, yes.
