Subject: mvebu: mark all mtd partitions on GL.iNet GL-MV1000 read-only
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=22436d762bbd872c347a7b1ef21c474625435ff8;p=openwrt%2Fstaging%2Flinusw.git

mvebu: mark all mtd partitions on GL.iNet GL-MV1000 read-only

On this device, two of the three defined MTD partitions are
automatically set to read-only, since they do not end at an
erase/write block boundary.

In particular, the only partition remaining writable is the
one holding the u-boot bootloader.

Mark all of the partitions read-only, at least until a better
understanding of why the layout has been laid out this way is
gained.
