      4 Subject: mtdsplit: find magic of little-endian JFFS2
      5 
      6 On a little-endian CPU, the little-endian JFFS2 magic
      7 appears to be word-swapped.
      8 
      9 There is probably a better way to implement this; if you are reading
     10 this patch you are probably well-qualified to do that and upstream it
     11 to OpenWrt
