3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ben Hutchings <bhutchings@xxxxxxxxxxxxxx>
[ Upstream commit bfeed902946a31692e7a24ed355b6d13ac37d014 ]
On big-endian systems the MTD partition names currently have mangled
subtype numbers and are not recognised by the firmware update tool
(sfupdate).
