"mxicy" looks strange to me, I know it has been used in the past and
cannot be removed, but I don't think it is wise to continue using it
while your use "mxic" in all your other contributions. I would update
the prefix to mxic here and fill-in the relevant doc.

Also, what is nand-morph? I thought we were okay for
the "-nand-controller" suffix.


Thanks,
