This is a nommu config?
If CONFIG_MMU=y,  GENERIC_IOMAP=y and iowrite8_rep() is available.

Greg: is there any reason we can't use GENERIC_IOMAP=y for the nommu

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
