Well, it's quite against the device centric model we have at the
moment... That made me hesitate.
But your reasons are very sound. It's quite a lot of cbfs accesses, and
generally I guess walking the device tree (in coreboot it's even a
memory op, and not a pci config space op) is cheaper than walking all of
the rom all of the time...
