The following set of patches applies on top of for-next branch.
Patches verified on: omap3430-SDP, omap3630-sdp, zoom3 and beagle board
And these are the patches required to address the following input -
1. The NAND driver needs to stop tinkering with the GPMC registers
The omap General Purpose Memory Controller (GPMC) registers are omap
specific, and not driver specific. Tinkering with these registers can
cause issues with the other devices on the GPMC.
2. Passing hardcoded GPMC_CS0_BASE needs to go from the board files
Passing hardcoded GPMC virtual addressess is sure way to mess up things.
This should all become unnecessary once the NAND drivers stops messing
with the GPMC registers directly.
Changes in this series -
Unused function removed.
Functions related to ecc and prefetch engine are optimized.
Few functionality was missing like - There should be some locking as only
one chipselect can use the ECC or prefetch engine at a time. If you have
NAND in two chipselects, bad things would happen.
Additionally, it was needed to implement more functions for the platform
init code to use.
