This #error message was included, because if you look at the code
you'll see that the read/write accessors are 32-bit operations *(u32 *
).  These may or may not work on your configuration.  It should be
trivial to write accessors for a 16-bit bus, but nobody had hardware
to try it out on.  Please do so and submit a patch.
