Yes, that should be possible. I'll address this in the next revision.

I've intentionally kept the initial revisions of this series simple and
didn't want to introduce yet another board (other than the SBSA board).

But if you think introducing a usage of the configuration I think either
qemu_aarch64_virt_efi_defconfig or arm_foundationv8_efi_defconfig would
make sense.
The former would be easier and more accessible to test by most people.
But the latter would be a more accurate emulation of something that
would resemble the SBBR standard.
