Cover letter [PATCH 0/4] powerpc/mpc5200: Add support for ATA DMA

Hey everyone; here is the latest version of the patches to add ATA DMA support for the MPC5200. I'm pretty confident that these patches won't break anything and by default DMA support is turned off. Users wanting to test ATA DMA should add the 'libata.force=udma2' parameter to the kernel command line.

Since there are just minor changes from the last iteration and a couple of changes have been broken out into separate patches, I'm pushing this series out to my -next tree for Paul to pick up.

Cheers,
g.
