Bugzilla 771 - Fix pata_fsl libata driver DMA mode
Patch for Bugzilla 771 - Fix pata_fsl libata driver DMA mode. Full
sglist DMA working on linux 2.6.22 for MX27/MX31. Not fast enough on
MX27, though. MX31 is as fast as the old mxc_ide driver. Writes are
unreliable on MX27 TO1. Beyond UDMA3 on MX27 wasn't 100% reliable.
