Subject[PATCH 4.4 041/312] ARM: dts: orion5x: fix the missing mtd flash on linkstation lswtgl
Date
From: Roger Shimizu <rogershimizu@gmail.com>

commit 44361a2cc13493fc41216d33bb9a562ec3a9cc4e upstream.

MTD flash stores u-boot and u-boot environment on linkstation lswtgl.
The latter one can be easily read/write by u-boot-tools package in Debian.

Fixes: dc57844a736f ("ARM: dts: orion5x: add buffalo linkstation ls-wtgl")
