[U-Boot-Users] [PATCH 3/9] NAND update

The following modifications have been made in cpu/
Note that the patch-series is broken unless it is seen as one single patch. It is broken up to multiple emails to fit the size limit.
We have set up a git repository were you can pull the complete patch: http://git.tandberg.com/tandberg/u-boot.git
Best regards William
