Add NAND support (including spl) on IFC, such as is found on the p1010.
Note that using hardware ECC on IFC with small-page NAND (which is what comes on the p1010rdb reference board) means there will be insufficient OOB space for JFFS2, since IFC does not support 1-bit ECC. UBI should work, as it does not use OOB for anything but ECC.
When hardware ECC is not enabled in CSOR, software ECC is now used.

Scott,
Do you want to take this via nand tree or just have me pull it in via 85xx with the other P1010 patches?
