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? -- dwmw2
