ARM: mvebu: Netgear RN102: Use Hardware BCH ECC
commit ace8578182dc347b043c0825b9873f62fdaa5b77 upstream. The bootloader on the Netgear ReadyNAS RN102 uses Hardware BCH ECC (strength = 4), while the pxa3xx NAND driver by default uses Hamming ECC (strength = 1). This patch changes the ECC mode on these machines to match that of the bootloader and of the stock firmware. That way, it is now possible to update the kernel from userland (e.g. using standard tools from mtd-utils package); u-boot will happily load and boot it.
