My first thought would be to leave serial_ppc.c out of the conversion,
but that would be tricky given how the series is structured (with the
temporary CONFIG).

Perhaps a TODO on the #define above since it should be cleaned up, and
we want to make sure no one copies it.

Since you have it ready I think it should go in, with the TODO if you
can manage it.

Simon
