Looking at the gap between these two areas, I see that we would
initialize PCI between the two areas.  So there's probably boards with
PCI IDE devices that'll regress if I take this now.  What's the answer?
Long term, device model.  Short term?  Is there a specific upstream
platform that you're seeing the problem or, or just custom / out of
tree?
