Thu Nov 24 16:44:01 CET 2011


The TAM3517 is a SOM module that can be used on custom boards.
The patch add a common configuration file that is included
by the boards using this module.

Changes since V1:
- CONFIG_OMAP_EHCI_PHY1_RESET_GPIO (Igor Grinberg)
- Used inline instead of adding unuseful defines
- rebased on latest posted patches for AM3517
- drop mixing of space an tabs (Igor Grinberg)
- move default environment into the common file
- sort lists (W. Denk)
- do not remove CONFIG_CMD_IMI (W. Denk)
- drop CONFIG_SYS_NAND_ADDR (W. Denk)
- coding styles (several comments)
- add redundant environment (W. Denk)
- drop completely CFI setup (W. Denk)
