Is there any change can we clean this up?

and potentially add those flags for  dealing with the  CTS & RTS   ,  
that may not be used on every board,  because this clean up sit's in  
my minor changes for the YL9200, specifically to  re-jig the USARTS  
lines so that we can separate  RXD TXD , from a forced requirment to  
use  control lines when using  232
