WNDR3700v4 (AR71xx NAND) fails to boot after 3.18 change

Component: kernel Version: Trunk

Description

Kernel panics due to failing to mount root which in turn is the result of an UBI failure:

[ 3.180000] UBI: auto-attach mtd8
[ 3.180000] UBI: attaching mtd8 to ubi0
[ 3.390000] UBI error: scan_peb: bad image sequence number 1577530812 in PEB 168, expected 1752529953
[ 3.400000] Erase counter header dump:

[ 3.440000] UBIFS error (pid 1): ubifs_mount: cannot open "ubi0:rootfs", error -19

No problems if the AR71xx Makefile is switched back to using 3.14

Update:

This is likely due to 3.18 not having /target/linux/generic/patches-3.14/490-mtd-ubi-add-EOF-marker-support.patch ported over to it.
