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.muel...@elsoft.ch>
---
Changes for V2:
- delete config.mk
Changes for V3:
- adjust patch meta info
