Well, obviously its a device tree generator bug, the driver code is
perfect.  :-P

In all seriousness though, the '8-bit' property has been present for a
while now and needs to be retained to not break existing users.  It
would be okay for the driver to be modified to *also* check for the
xlnx,mem-width property, but the better solution is to modify the
device tree generator.  Plus, the '8-bit' property is the documented
binding in Documentation/powerpc/dts-bindings/xilinx.txt

Cheers,
