[PATCH][SERIAL] mpsc updates
From: Mark A. Greer
Date: Tue Jan 25 2005 - 19:55:25 EST
Hi again, Andrew.
This patch:
- replaces several macros with the actual code
- change the type of pointer variables from u32 to void *
- removes unecessary casts
- puts the contents of mpsc_defs.h into mpsc.h and removes the mpsc_defs.h
- reflects the new names of some structs
- cleans up some whitespace
