    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.
