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).

return a struct device * of attached device, or NULL if device attach failed,
rather than 1/0 for success/failure, so that code that bus code which needs
to know what the child device is doesn't have to open-code a hacked variant
of config_found(). Make config_attach() return struct device *, rather than
void, to facilitate that.
* Add an ACB_RESET flag, so that a BUS DEVICE RESET can be queued within the
driver.
* If ACB_ABORT or ACB_RESET is set during reselection, schedule a message and
assert ATN.
* Optimize aic_datain_pio(), aic_dataout_pio() and aicintr() somewhat.
* Schedule a timeout only when we select the target, so that commands can't
time out prematurely.
temporarily revert bus config order back to isa->eisa->pci
until port allocation/accounting is ready (XXX).
works around problem of the if_ep driver's probe function trashing
an adaptec 2940 if the BIOS maps it in at port 0xf000. (the
BIOS on my new P166 does this, ... the BIOS on my P133's does not).
without this the P166 system will reset as soon as spl0() is called
(autoconf.c) making it impossible to install the OS.

an autochanger driver written by the Systems Programming Group at the
University of Utah Computer Science Department (currently residing
