If the next available mailbox is not in the free state, print a warning
and handle the condition as a temporary resource shortage.  The condition
should never happen, but we shouldn't panic since recovery is possible.

d0993d7584 Fix probes when a port address is specified.
Convert from BT'isms to AHA'isms

Don't fail the probe if the illegal command bit is set in the status
register.  If the BusLogic MultiMaster probe preceeded us, it may well
have determined that the card we are attaching to was not a true MultiMaster
by sending us a command that fails on the 154X.

Reset the adapter before doing the inquiry.  This provides extra sanity
and will also clear the illegal command status bit that my be left over
from the MultiMaster probe.

ca1a3d8c33 Reduce the number of ccbs to 16, per the aha documentation. Move
bogus comment to proper place.

This should fix the hangs people are seeing under very heavy load, at
least it does for me.  Please let me know if you continue to have
problems.

bb415a7e88 Fix breakage introduced by last patch. bde has added CC_QUIET flag to
hasseen_isadev so this will be less noisy when conflicts do exist.
Also eliminate redundant warnings about conflicts.

19bed41a5d Fix conficts in probe:
o For bt and aha only probe the one I/O range if a specific I/O is specified
  in the config file.
o Don't even try to probe I/O ranges that have been seen already.
o If we conflict with an IRQ or DRQ, then fail the probe.

command that comes in through xpt_polled_action works correctly.

667b14c256 Misc cleanup and probe rework:
o Use the board id command to find out what kind of board
	  we're talking to.  If we're talking to a board that is has
	  an ID that is shared between boards supported by the aha
	  driver and the bt driver, then use the bt's geometry
	  register to weed out the bt cards.  Otherwise assume that we
	  support this card.
	o Remove bt esetup command sending to the card.  It seems to
	  wedge too many cards.
	o Revert to doing a soft reset after an invalid command.  This
	  change didn't fix anything, so I'm backing it out.  The
	  whole issue of card resetting needs to be revisisted at some
	  point so that we can do it properly on all hardware.
	o GC unused stuff in some places.

6a04333133 Perform a hard reset on cards when the command fails. This should help
those people that have cards that become wedged when a bogus command is
issued that are too wedged to have a soft reset help.

8d74c4aa15 Several minor cleanups, inspired by bug reports and the old driver:
o Unlock mailbox interface if we have a new card.  Before only newer cards
  (B or newer) that had the BIOS disabled would probe.  Cards with the
  BIOS enabled would fail to probe in the mailbox initialization code.
o Increase the number of ccbs and sg to 17 from 16 to support 64k I/O
  on a non page aligned boundary.  Ideas for dynamic determination of this
  value welcomed, as more of these are better.
o Took credit for this driver, even though I derived it from Justin's code.
  Made sure that Justin's copyright from bt.c was preserved, along with
  his name, since the error handling code is nearly identical.  Add my
  own, identical copyright.  Point people to aha_isa.c.

Cards tested: 1542C and 1542CF.  The B and CP might work now as well,
but logistical problems precluded me from testing them this evening
(if you have jumper settings for the B card, please send me private
mail).

empty but regressed to including it here.
