[PATCH v3 0/6] mtd: nand: Fix support for NAND DMA prefetch

[Franklin S Cooper Jr]

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.
