1. Please send always the mailing list, too!

2. Use the rework101229 branch (minus the last 5 patches).

There is lot of cleanup done in the header files and the ATMEL drivers.
The at91sam9260(9xe)ek board builds fine and works.
Use that as a template or reference what to do.
You should *only* need to adapt board/*/files and your configs/<board>.h
files. And of course updated entries in boards.cfg.

Once the rework is done for *almost* *ALL* AT91 SoCs it will be put for
review into mainline, probably for the 06.2011 U-Boot.

Best Regards,
Reinhard
