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.
