What I thought was:
	(a) SCI doesn't have flow control feature with that
	(b) Someone may implement RTS/CTS using some port signal,
	    for his board
	(c) In that case, he may want to implement it here.

Please go ahead!  Currently, SCI and SCIF is compile time option.  At
that time, I didn't understand SH7750 (or SH7709) has both of SCI and
SCIF.  It would be good if:

	(1) We use both of SCI and SCIF.
	(2) We can change which is primary on runtime. (command line option)

Thought?
