Subject: ARM: dts: orion5x: fix the missing mtd flash on linkstation lswtgl
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=44361a2cc13493fc41216d33bb9a562ec3a9cc4e;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ARM: dts: orion5x: fix the missing mtd flash on linkstation lswtgl

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.
