[U-Boot] [PATCH v2 0/9] avr32 cleanups and GPIO port mux support

[Haavard Skinnemoen]

The following patch series is a round of cleanups to the avr32 code,
including board code. It shouldn't result in any functional changes or
significant changes in the size of the u-boot image, but it should
make it easier to add support for new chips and boards in the future,
and it also makes some of the existing board code a bit cleaner.

It also adds support for the "GPIO" port mux, which can be found on
newer AVR32 chips, i.e. all UC3 devices as well as upcoming AP7
devices. Work is currently ongoing to use this on both the UC3 and the
AP7 front, so even though there are currently no in-tree users of the
GPIO mux, I want to get it supported at least semi-officially in order
to reduce duplication of effort.

This patch series obsoletes and extends the series that was previously
posted here:

  http://lists.denx.de/pipermail/u-boot/2008-August/039672.html

Since the merge window is supposed to be closed now, I'm planning to
push this during the next release cycle, which should leave plenty of
time for testing.

This series has also been pushed out to the 'cleanups' branch of

  git://git.denx.de/u-boot-avr32.git cleanups

which I intend to merge into 'next' in a few days if nobody complains.
The 'cleanups' branch may get rebased, so please don't base any new
work on it yet.
