[U-Boot] [PATCH] update SMDK2410 port
David Müller

Fri Dec 3 16:43:31 CET 2010
Hello
This patch brings the SMDK2410 port in sync with the latest U-Boot
version by doing the following:
- do the necessary adjustments to support the ARM relocation feature
- use the CFI flash driver (and removing the old one)
