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.
