Ah, great. In that case, that seems like the best approach. It should
make it easier to integrate into OVMF too, because it'll just be using
the 'standard' flash storage code with a different physical location.
Hopefully.
Can we get away with exposing an additional flash device in the physical
memory map immediately below the BIOS "ROM" and giving the firmware a
way to discover its location? Or do we need to do it "cleanly" by making
it a BAR of a PCI device?
