Description of problem:
'serial.c' calls the serial device driver's 'set_config' with 
a 'cyg_uint32' buffer. At least two serial device drivers, 'ser_16x5x.c' 
and 'sh_scif_serial.c', assume 'buf' points to a 'cyg_uint8'.  A big-endian 
target will fail.

I suspect most serial device drivers will have this problem because they all 
seem be derived from the same source.  This problem is not limited to the 2.0 
beta.  It also appears in the CVS sources.

I suggest better comments in 'serial.h' could have prevented this.
