Oops, I think it should be renamed for consistency.

I believe there's only one chip in the GXM family (S912) so it might be
that we could either drop the -s912 from the q20x boards or, add it to
the nexbox.

I lean towards dropping the -s912 since there's a single chip in GXM.
(FWIW, GXL has more than one chip in the family so we added the chip
there.)

No.  Unless Neil or you thing otherwise, I think we should send a patch
to drop the -s912 from the q20x boards instead.  (where "we" == Neil) ;)
