Agreed, when I get some time I'll take a look at this again.  I now have
another PXA based board using built-in UARTs for the debug console so
I can test a little more thoroughly.  So for now:

on the revert.  Sorry again for the churn - dropped the ball on this
one.

I'm more of the opinion that we aren't that far from being able to block
board files - I am 100% using device-tree and now have a single kernel
that will boot on 3 different Elecsys boards.  Not to mention the fact
that I can't imagine there's a whole lot of new hardware work in the PXA
realm.

I have posted the work to my github account
(http://github.com/aeruder/linux) but it is tough work getting things
cleaned up to not break anyone not using DT (HAH, see this thread),
documented, and submitted.  I was really hoping the big mmc/DMA rewrite
would drop into mainline at some point since that is one of the more
terrible hacks I'm still maintaining over here.

Cheers,
Andy
