goldfish: NAND flash driver
Fold together the NAND driver for Goldfish from Arve with cleanups by Jun Nakajima and a tidy up to 3.7 and checkpatch. This provides a virtual flash driver for the Goldfish Android Virtual Platform, and which is normally used as the root file system when testing emulated devices. Signed-off-by: Mike A.
