This brings the core NAND code up to date with the Linux kernel. Since there were several drivers in Linux as of the last update that are not in u-boot, I'm not bringing over new drivers that have been added since in the absence of an interested party. I did not update OneNAND since it was recently synced by Kyungmin Park, and I'm not sure exactly what the common ancestor is. Signed-off-by: Scott Wood <scottwood@freescale.com>
