Simplify the initialization of adapters by pulling all card specific
initialization to the card specific modules.
Set the Latency timer and Burst len to good values if thery are not
initialized during post or are reset during chip reset.
Properly identify and handle external SCB SRAM. The code was false
id'ing 255 SCBs on aic7880 chips.

pci now uses a different interrupt handler type for interrupts that it
dispatches and the isa interrupt handler type for the interrupts that
it handles.
Reduce default value of pcicb_membase to 0x2000000 (from 0x4000000)
since this seems to be the lower bound used by many systems.

all the other bt_XXX() functions in i386/scsi/bt*.
This the important effect of forcing a link error if the user is
still using the old "vector btintr" which is dangerously wrong
after Justin's updates to the driver.
The correct isa vector line for the bt driver is "vector bt_isa_intr".
Justin mentioned this in the commit message and updated LINT and
GENERIC. This change is to enforce that.. :-)
most devsw referenced functions are now static, as they are
in the same file as their devsw structure. I've also added DEVFS
support for nearly every device in the system, however
many of the devices have 'incorrect' names under DEVFS
because I couldn't quickly work out the correct naming conventions.
(but devfs won't be coming on line for a month or so anyhow so that doesn't
matter)
If you "OWN" a device which would normally have an entry in /dev
then search for the devfs_add_devsw() entries and munge to make them right..
check out similar devices to see what I might have done in them in you
can't see what's going on..
for a laugh compare conf.c conf.h defore and after... :)
I have not doen DEVFS entries for any DISKSLICE devices yet as that will be
a much more complicated job.. (pass 5 :)
pass 4 will be to make the devsw tables of type (cdevsw * )
rather than (cdevsw)
seems to work here..
complaints to the usual places.. :)
Removed ifnet.if_init and ifnet.if_reset as they are generally unused.
Change the parameter passed to if_watchdog to be a ifnet * rather than
a unit number. All of this is an attempt to move toward not needing an
array of softc pointers (which is usually static in size) to point to
the driver softc.
if_ed.c:
Changed some of the argument passing to some functions to make a little
more sense.
if_ep.c, if_vx.c:
Killed completely bogus use of if_timer. It was being set in such a way
that the interface was being reset once per second (blech!).
o Add signed/unsigned functionality to the matrox meteor device driver.
o Apply a few fixes to the sound driver.
o Add a ``SPIGOT_UNSECURE'' compile time definition so, if one defines
SPIGOT_UNSECURE in their conf file, then they can use the spigot w/o
root. There is a warning that this allows users access to the IO
page which is probably not secure.

Convert the remaining sysctl stuff to the new way of doing things.
the devconf stuff is the reason for the large number of files.
Cleaned up some compiler warnings while I were there.
incompatible with the type of a PCI interrupt handler.
Fixed the type of pdc_pci_ifintr(). The type of a PCI interrupt handler
is too generic to pass arbitrary struct pointers.
incompatible with the type of a PCI interrupt handler. A new entry
point `ahc_pci_intr()' is used for PCI. ISA and PCI interrupts are
penalized equally (:-) by calling a common handler `ahc_intr()'. This
should be reorganized. Some strings now name the wrong function...

this driver hasn't been checked but as a separate module, bringing it in won't
break anything else and it't the best way of testing it......

If RAMENB is set in devconfig, walk the external SCBs. Some Intel Xpress
motherboards set this bit.
For external SCBs for the 3940. It doesn't set RAMPS or RAMENB, but does
have the ram.
"I screwed the initialization of the burstsize. Right now it will default
to 0 (which can cause corruption problems on high latency PCI buses). It
should be set to 8 longwords to avoid problems with certain PCI chipsets."

for now since I don't have any documentation on this card yet and it
is software compatible with the earlier cards.
The 2940 *Ultra* is Adaptec's push to take SCSI to 20MHz bus rates. Its
based on the aic7880 chip which is the successor to the aic7870.
and for the 53c810ap, the improved version of the 53c810.
The driver should work with all those controllers, but doesn't know
about any of their advanced features.

This allows for easy modification of the actual virtual to physical

Make all applicable references to physical address values use the above
macros instead of calls to vtophys().
