[PATCH 1/2] Added support for Designware SATA controller driver

[Feng Kan]

Hi Scott:

I agree with your statement, however this driver is wrapped with this 
AHB DMA controller.
It would be very hard for it to work on non 460EX platforms. I can 
expand the depend in
the future if it is available on more cores.

Thanks
Feng Kan
