This patchset fixes it so SOCs that use the SDMA can make use of the NAND DMA prefetch. I've decided to split this patchset from the slightly larger patchset that included EDMA support. Adding EDMA support will be added in a later patchset. Tested using the latest master on: am37 gp evm Due to a silicon issue Dra7 SoCs are unable to use NAND DMA prefetch.
