Subject: ARM: dts: orion5x: fix the missing mtd flash on linkstation lswtgl
|
|
Origin: https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/?id=44361a2cc13493fc41216d33bb9a562ec3a9cc4e
|
|
|
|
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")
