- changes for v2:
- add comments from Bo Shen
- use gpio api
- remove unneccessary comment
- use at91_wait_for_reset()
- remove unneccessary code in board file
- Coding Style cleanup (tabs and unneccessary 1 after config define
removed, use ".xxx = x" notation for initializing structs)
- remove reset_phy()
- remove CONFIG_SYS_MEMTEST_x defines, as mtest command
is not used on this board.
- changes load address
- delete lcd support
- add comments from Andreas Bießmann:
- rearrange some init calls
- remove some unneeded ifdef
