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.
