thorpej 940ccbc5df Fix typo that caused sun4 machines to be misidentified as sun4c-class.
Fixes reported problem of binstall not stripping the a.out header from
the boot block on sun4 machines.
1996-04-07 20:00:12 +00:00
thorpej 77366064b8 Fix oversight in sun4m changes: the CPU attach code moved, so the CPU
was never getting attached on a sun4 machine.  Fix this so that the
cache and FPU get enabled on sun4 machines.  (Believe me, a 4/260 is
slot enough, *with* the cache...)

thorpej d68e57ee64 Make this compile again on a SUN4-only kernel. (Avoid "unused foo"
warnings from gcc -Wall.  While the optimizer is smart enough to
eliminate dead code, it looks like the rest of gcc doesn't Get It.)

chuck e50fc72424 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).   we now ignore these entries on a sun4 since
they could never be valid (eliminates a 'panic:alignment' fault at bootup).
1996-04-05 21:50:05 +00:00
chuck a7c600676f 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).

Note on multi-architecture kernels: most architecture dependent traps are
forked off directly by having a separate trap table for each (sun4,sun4c,sun4m)
This reduces the number of tests on `cputyp' significantly, and it's easier
on the mind. There are still some entry points that need to test `cputyp',
most notably microtime().. yuck.
