CVS: blob/include/blob serial.h,1.2,1.3

[Erik M. <er...@us...>]

Update of /cvsroot/blob/blob/include/blob
In directory usw-pr-cvs1:/tmp/cvs-serv8566/include/blob

Modified Files:
	serial.h 
Log Message:
Happy new year!

This is the start of a new serial driver that should make porting blob to
non-StrongARM architectures easier. The SA11x0 driver is implemented, but
completely untested at the moment. It's trivial to do the rest of the serial
code, but I'd better go to bed, or otherwise Jan-Derk will complain that
I'm working too late ;) Part two follows tomorrow.
