why use serial_core at all ? seems like you could just use the tty
layer directly. i did that with drivers/char/bfin_jtag_comm.c.

although, there's the suggestion in the air that my jtag driver could
be converted to the HVC framework to even further simplify things.
but no one thinks it should be serial_core :).
