5253b892e9 Add a hardware dependent initialization function lehwinit() 
to support selecting UTP media on sun4m
 1996-04-22 02:37:10 +00:00

709298a10a - Changed Sun4m DMA chip support to detect and use maximum available SBus 
burst size when transferring data.
- Changed ledma attach code to pay attention to the PROM's notion of what
  cable type is being used. Note that this patch does not fix the problem
  recently discussed on port-sparc; in most cases the PROM doesn't know
  what cable type is being used. The default is now TP rather than AUI,
  though. A complete fix is forthcoming.

d7d306aeb7 change LANCE copy & zero functions' names to start with amd7990_, and 
remove their 'integrate' (usually defined to be 'static') keywords.
when lance drivers are split up by attachment, more than one file will
reference the copy/zero functions (i.e. not just the file that pulls in
am7990.c... and eventually inclusion of am7990.c should go away entirely).

c28fcc3539 Use extra value in `struct bootpath' to describe the PROM's bootpath better. 
Use the bootpath[] array in setroot() to determine partition info in case

fake_bootpath() to simplify dk_establish().

devices (e.g. busses) should the need for this ever arise.

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...)

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.)

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).

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).

8de1fd22bc Add sun4m support. Many, many changes.. 
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.
