Lennert Buytenhek 167e1770e5 [MTD] ixp2000: Remove port setting code
Setting the slowport to 8-bit mode is something that ought to be
done in the IXP2000 generic code, not in the MTD map driver.  See
the description for ARM patch 2493/1 for an explanation.

http://www.arm.linux.org.uk/developer/patches/viewpatch.php?id=2493/1

Now that 2493/1 has been accepted and will be upstream soon, this
doesn't need to be done in the map driver anymore.

Ben Dooks 011b2a3627 [MTD] Fixup probing logic for single 16bit devices
The change to the generic probe to look for the
smallest width of chip first is causing some problems
on boards with a single 16bit device.

The problem seems to be the jedec_match() is truncating
the device-id read from the table to match against the
one read from the hardware, causing a match against the
partial id of some chips with 16bit IDs (such as the
SST39LF160)

This fixes things for my own board, but something may
need to be done if the same problem is exhibited for
chips with an 8bit ID
