Hi Wolfgang,
Please pull from the 'for-upstream' branch of
git://www.atmel.no/~hskinnemoen/u-boot/avr32 for-upstream
to receive the updates listed below.
This is basically the same pull request I sent a while ago rebased against your latest git tree. It contains some major restructuring of the avr32 code, ultimately resulting in it relocating itself to SDRAM at startup.
There are also some changes to the clock- and portmux management code in here, which was necessary because the old code used to keep some state around in global variables. The new code provides mostly the same functionality, is simpler and works without a writable data section.
I've tested this on my own board for a couple of months now, and everything seems to be fine. There are some unresolved issues with cfi flash support, but this lot needs to go in before we can even think about dropping the custom flash driver.
I'm not attaching any combined patch since it's quite big and has been posted before:
