commit 225b94cd upstream. The bootloader on the Netgear ReadyNAS RN104 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. The issue was initially reported and fixed by Ben Pedell for RN102. The RN104 shares the same Hynix H27U1G8F2BTR NAND flash and setup. This patch is based on Ben's fix for RN102.
