Yes, please give us a rationale for all this mess. I really don't like
the sleep wrappers or the "early" PCI device; would it be easier to
extract some of the core disabling MMIO from the quirks and re-use it
for a totally separate set of early quirk functions? Like Ben
suggested, making it totally arch specific would be a good option,
though presumably most arches don't need this (again if you explained
why/when this was needed maybe we could come up with a better
solution, or just ignore the problem if you're trying to fix a
pre-production board again with all sorts of broken stuff).
