Subject: mediatek: define NMBM management region for WAX220
X-Git-Url: http://git.openwrt.org/?a=commitdiff_plain;h=92eec257dd562547bc08ee76c1901eb22b66937c;p=openwrt%2Fstaging%2Fnbd.git

mediatek: define NMBM management region for WAX220

The NETGEAR WAX220 employs NMBM on SPI-NAND. In order to avoid dealing
with invalid factory data, enable NMBM in the area preceding the UBI
volume.
