NAND DMA prefetch has been broken for awhile and seems to have only worked for SDMA based devices This patchset fixes DMA prefetch to work on both EDMA and SDMA devices Test on: am335x gp evm am437x gp evm am37x gp evm This rev is pretty much the same as v2 which was blocked due to dependencies to Roger's update GPMC/NAND rework. This updated rev removes this dependency. Also it fixes an issue that was introduced when the eDMA driver was recently updated.
