Update of /cvsroot/src/sys/arch/mac68k/dev
In directory netbsd1:/var/slash-tmp/cvs-serv21090

Modified Files:
	grf.c grf_iv.c grf_mv.c grfvar.h 
Log Message:
Overhaul grf drivers to correct recent problems with X and dt
(address error faults), as well as other reported problems:

 - Simplify grfmv_phys() to work like grfiv_phys(), and eliminate the
   second argument to both, as we don't use it anyway.
 - Handle fbbase and fboff consistently throughout.  Closes PR 3862.
 - Eliminate grfaddr() by pulling it into grfmmap(), which is the
   only place it was used, previously.
 - grfmap() now gets the physical address of the framebuffer from
   the appropriate driver, rather than try to compute it by itself.
   Be careful with aligning the base to a page address and increase
   the length of the mapped region appropriately.  Closes PR 2867.
