Yup, looks I forgot a quilt ref or something. I'll check. I'll also give
port 1 and 2 a go (after fixing the DT).

I also want to change the config space code to use some fixmap type
direct mapping/unmapping to remove bus number limitations as soon as
Kumar has implemented the fixmap stuff, since he seems to be working on
it now.
