My Daught board (LPC Expansion) uses the NSC PC87364, the wich is the
same WINBOND 87364. I compile successfull the last code, but i was not
able to see anything on serial port 0 of CS5535. But something is clear
for me now: if you don't have VSA initialized, you aren't able for using
serial port of companion chip.  As a matter of fact, you are probably
sending the bytes to port 0 of winbond super i/o, isn' t ?
Are you really sending the debug output for port 0 of  WINBOND 87364 ?
