[U-Boot] [PATCH V3] update VCMA9 port

11 Jan 2011

This patch brings the VCMA9 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)
 - various cleanups and coding style fixes
 - remove the unneeded config.mk file
Signed-off-by: David Müller d.mueller@elsoft.ch
---
Changes for V2:
 - delete config.mk
Changes for V3:
 - adjust patch meta info
