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).
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).
- split softc size and match/attach out from cfdriver into
a new struct cfattach.
- new "attach" directive for files.*. May specify the name of
the cfattach structure, so that devices may be easily attached
to parents with different autoconfiguration semantics.
[these bugs apply to the xy as well as the xd driver]
[1] check return value from malloc() for NULL before trying to bzero it.
[2] use "=" rather than "|=" when writing to CSR (otherwise you may
ACK something you don't mean to!).

of bwtwo, cgfour, cgsix, and cgeight. Includes support for attaching
the overlay plane of the cgfour and cgeight as a bwtwo instance (a'la
SunOS).
P4 register descriptions, cgfour driver, and cgeight driver partially
derived from OpenBSD.
This code may still need polishing.
