powerpc/mpc5200: Add MDMA/UDMA support to MPC5200 ATA driver
This patch adds MDMA/UDMA support using BestComm for DMA on the MPC5200 platform. Based heavily on previous work by Freescale (Bernard Kuhn, John Rigby) and Domen Puncer. With this patch, a SanDisk Extreme IV CF card gets read speeds of approximately 26.70 MB/sec. Signed-off-by: Tim Yamin <plasm@roo.me.uk> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
