The squashfs+jffs2 root filesystem only came up as read-only
and the config would not take:
[ 25.600237] mount_root: Could not open mtd device: /dev/mtd4
[ 25.634674] mount_root: reading rootfs_data failed
[ 25.665346] mount_root: Could not open mtd device: /dev/mtd3
[ 25.699802] mount_root: reading rootfs failed
[ 25.726426] mount_root: mounting /dev/root
Well that is not very strange since the whole firmware partition
is made read-only in the device tree. Let's fix that by augmenting
the OpenWrt patch.
