It it a firmware for many PC systems. It brings up CPU, RAM and
buses, including HyperTransport, PCI Express, PCI and PnP.

That would also be true yes, however maybe the resource allocator in
SeaBIOS for qemu is so far simpler than the generic one in coreboot,
so it was not a lot of duplicated code, while the PCIe seems to be a
fairly big addition, of something that I think coreboot may already
be able to do. It seems to me that now may be a time to consider if
and how coreboot fits with qemu.
