device and a printable "external name" (name + unit number), thus eliminating
if_name and if_unit. Updated interface to (*if_watchdog)() and (*if_start)()
to take a struct ifnet *, rather than a unit number.
naming conflicts between bus attachments on ports that can have
multiple instances of the LANCE.
Changed struct ifnet to have a pointer to the softc of the underlying
device and a printable "external name" (name + unit number), thus eliminating
if_name and if_unit. Updated interface to (*if_watchdog)() and (*if_start)()
to take a struct ifnet *, rather than a unit number.
after changing the cable type, as specified in the chip documentation.
Also, sanity-check that sc_dma is valid in case a Sun4m ever exists without
a ledma.
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.
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).
Use the bootpath[] array in setroot() to determine partition info in case
of boot devices of type DV_DISK. Also, precook more SCSI device info in
fake_bootpath() to simplify dk_establish().
in favour of storing the device pointer in the bootpath[] element corresponding
to the boot device. This also allows the opportunity to get to "intermediate"
devices (e.g. busses) should the need for this ever arise.
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...)
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).
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).
