Ah yes, now you mention it ...  And still that doesn't frighten me that much,
and certainly much less than clocks or dma stuff. Only the headers might be
troublesome, and pxafb will certainly be a big rework, but that's for the next
step :)

As for the per-board header files, as long as they're used only within mach-pxa
and not outside (ie. not in drivers) I must admit I don't see what might be a
problem.

As for XIP support, I don't have a clear view if it's a requirement for
multiplatform nor if it works in these builds.

Well, that makes me a goal to reach, doesn't it ? I'll stick to optimism here,
and we'll see within a year how far I manage to go :)

Cheers.
