nisimura 4371d91433 Have MI ncr53c9x_attach() the 2nd and 3rd arguments for scsipi_adater
and scsipi_device respectively, with size reduction of ncr53c9x_softc.
Specifying NULL instructs the driver to use default adapter and default
device codes. Every target port has ncr53c9x_attach(sc, NULL, NULL) anyway.

oster 39a667120f In the event that an up-to-date component cannot be located for a specific
position, see if there is a failed component still hanging around that
we can use instead (but still mark it as failed).  This leads to more
reasonable behaviour (and fewer surprises!) when autoconfiguring and
failed (or previously failed) components are still on the system.

ragge 16f02724d6 Some updates to the DEUNA driver:
- Change the transmit logic to send from a pre-allocated buffer instead
  of doing DMA out of the mbufs directly. Timing shows that it takes
  4 times longer to map in the mbufs via the sgmap routines instead of
  just copying the data! This must be fixed sometine in the future.
- A bunch of other minor fixes.

fvdl 3713246e34 Don't bother searching the qinfifo for SCBs to requeue in the BUSY

oster 26b4598736 Components which match on everything but the mod_counter are
renegades, and must be handled correctly.  In particular, they should
be added to their old auto-config set, but then immediately released.
Failing to do otherwise means that they potentialy end up in a
different (and competing!) RAID set which may auto-configure in place
of the correct one, and cause all sorts of chaos at auto-configure
time.

ragge 38d5764cd1 Fix for a driver bug provided by Jon W Grubbs (jgrubbs@megsinet.net).
This bug is only visible on some disks, and I have verified that it works
correctly on VAX. However, du to the author, it is a problem on other
machines/disks as well. Here's the author's comments:

> The MI code for the NCR5380 has a small bug in it  The RZ56 wants to
> negotiate for Synchronous Data Transfers and when it does, the current code
> looks like it will send a REJECT message as the spec calls for when we cant
> handle the request.  However, a couple of lines of code in the
> ncr5380_msg_in routine are missing wrt the PARITY message and anything that
> wants to send a REJECT message.  The ATN setup that is done in
> ncr_sched_msgout is immediately negated by the final byte ACK sequence in
> this routine.  This causes bad things to happen to an RZ56.

bouyer b063b2ec36 Separate the sheduler from the main script, allocate another DMA-safe
memory page for the sheduler. Put the main script in the on-chip RAM when
available.
Avoid a null-pointer dereference when DSA is invalid.

thorpej 4f92d2cd54 Update from Bill Studenmund <wrstuden@zembu.com>:
- Note that the FreeBSD driver distributed by Cyclades served as
  documentation on how the board works.
- Use the wait-until-pending-I/O-completes-before-loading-parameters
  command in czttyparam().
- Pass BREAKs up to the tty later properly.
- Garbage-collect some debugging code.

bouyer e662e86225 sd_interpret_sense() can be called from interrupt context; call scsipi_start()
with XS_CTL_ASYNC if the failed command was called with XS_CTL_ASYNC.
Add a SDF_RESTART flag to keep state, cleared in sddone().
A mounted disk can now spin down, it will propely spin up at the next access.

thorpej 071aed40ac A foolish consistency; most parts of the kernel use bp->b_data, so
change these from bp->b_un.b_addr to bp->b_data, as well.  This also
allows us more flexibility to experiment with other data buffer types
hung off of struct buf.
