From: Feng Kan fkan@amcc.com

Hi Stefan: I have addressed most of the issues except two. - I removed get_emac_phy_config, the board will use dip switch to determine if the bridge will be GMII or RGMII. I will submit it later when it is more mature. - I would like to keep redwood.h. It seems one of the guys have PCIe.c file that source this file. There will be alot more defines in this file. If you think this is still a problem. I will merge the redwood.h into redwood.c.

Thanks

The AMCC Redwood reference board uses the latest PowerPC 464 CPU processor combined with a rich mix of peripheral controllers. The board will support PCIe, mutiple Gig ethernet ports, advanced hardware RAID assistance and IEEE 1588.
