From: "Jens Scharsig (BuS Elektronik)" <esw@bus-elektronik.de>

- update clock settings for higher perfomance
- change standard baud rate to 115200
- fix flash base address
- remove unused defines
- add I2C support
- switch form board dependent flash to cfi
- remove board dependent flash code
- use sdram bank 0 instead of bank 1 on boot
- enable on board frame buffer instead external
- remove fake mac address form config
- add watchdog support
- add status led support

changes since V1: 

remove autodetect video, don't work on all hardware revisions

Hello,

I have seen this patch is marked as "Changes Requested" in
patchwork. But I have never get a request or comment.
Is there an real reason for this state?

regards Jens

I also do not see any such requests on the list, so it must have happened
by an accident. I'll change the patch status in patchwork.

Applied to staging/agust@denx.de after fixing a build warning and
some small style issues. Please next time use tools/checkpatch.pl
for checking the patches before submission. Thanks!
