Hi Robert,

as much as I like this series, I think you still have a long way to go before
PXA can really be multiplatform. Other parts that would need to be solved
include the various cpu_is_pxa*() checks in drivers, the per-board header
files, the way that the I/O space is mapped in the PCMCIA drivers and
the XIP support.

I think all of them are theoretically doable, but I wasn't expecting
to ever get there.
