[U-Boot] [PATCH 2/2] Kirkwood: openrd_base: Added SATA support

[Prafulla Wadaskar]

From: Prafulla Wadaskar <prafulla at pe-lt078.(none)>

This patch enables mvsata driver and related filesystem support.
The patch is tested for ide reset and ext2ls operation for a disk drive connected on SATA port0.
This patch depends upon the patche-series http://lists.denx.de/pipermail/u-boot/2010-August/074908.html
