From c238c3434129b28de67d01c22b7456b2dd138759 Mon Sep 17 00:00:00 2001 From: "klightspeed@killerwolves.net" Date: Wed, 10 Sep 2014 18:55:41 +1000 Subject: 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.
