Hi Robert,

I'm glad to see all this activity on PXA! You're reaching the amount of new
stuff that it's time to start splitting up in topics. I'll merge this branch
for this release, but I'm also going to go through below and show you how this
can/should be split up in the future.


First, take a look at our tree and how it's organized. Look at my presentation
from ELC 2014, or Arnd's from this year, to get an idea of the philosophy we
use and roughly how we categorize patches.

This is a fix or cleanup.

Cleanup.

Most of these are fixes/cleanups. With a burst of patches like this it can
sometimes be hard to rip them apart and put some in one bucked and others in
another. Feel free to keep them in a separate topic in that case
(magician-cleanup or similar)

Board code, of which we tend to have almost none these days. :-)

This could also be a topic on its own. We'd merge it into the cleanup branch at
our end, but you can provide it as a separate branch if you want.

cleanup.


Given that the bulk above was cleanup, that's also where I merged this branch
this time around.

Don't hesitate to ask if you have questions on how to handle this down the
road.
