Update of /a/cvsroot/src/sys/arch/sparc/sparc
In directory pain.lcs.mit.edu:/a/tmp/cvs-serv28890

Modified Files:
	autoconf.c 
Log Message:
make netbsd/sparc boot on sun4 once again.    the sun4m changes introduced
config lines for obio0 devices without addresses (thus cf->cf_loc[0] took
the default value of -1).   this caused autoconf.c to map memreg0 to 
obio physical address -1 (invalid).   as soon as we took a memory fault
the code in memfault_sun4 [locore] would get a Watchdog timeout when trying to
read memreg0 (a.k.a. par_err_reg).
