The mxc_nand driver is completely useless with

	5775ba3 (mtd: mxc_nand: fix several sparse warnings about incorrect address space)

but without this patch. So it would be great if we could have it in 3.5.
Or alternatively revert 5775ba3. This fix currently it sits as

	096bcc2 (mtd: mxc_nand: use 32bit copy functions)

in next/master.

Best regards
Uwe
