Now that we have lehwinit() for the Sun4m, make sure that we wait 20ms

after changing the cable type, as specified in the chip documentation.

a ledma.

- 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.

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).

Fix oversight in sun4m changes: the CPU attach code moved, so the CPU

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).

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).
