This is John Baldwin’s option for his reworked PCI bridge code. He did that as
a fallback in case he really messed up something. It introduces renumbering
of busses that don’t already have numbers assigned. It should be enabled on
ARM, but the required resource isn’t defined on arm, and some of the other
required glue doesn’t seem to be implemented for arm yet, which is why things
are the way they are at the moment. I think John intends for the option to go
away, and everything it covers will be ‘standard’.
