b7ae8b66ce Add locking to the bt(4) driver and mark it MPSAFE.
- Use device_printf() and device_get_unit() instead of storing the unit
  number in the softc.
- Remove use of explicit bus space handles and tags.
- Return an errno value from bt_eisa_attach() if an error occurs rather
  than -1.
- Use BUS_PROBE_DEFAULT rather than 0.

88ddf531d9 Classify all EISA cards with major firmware revions '2' as 742As.
This allows us to successfully attach early Storage Dimension cards.

Allocate mailboxes for the 742A bellow the 16MB limit.  Although these
cards seem to be able to deal with all other types of data anywhere
in a 32bit address space, 24bit addresses are required for mailboxes.

bt_eisa.c:
	Add device IDs for all Storage Dimension products I could
	find from their web site.

Thanks to Ted Mittelstaed for loaning me the equipment to diagnose
and fix these problems.

961b97d434 Back out the previous change to the queue(3) interface.
It was not discussed and should probably not happen.

d93fbc9916 Change the way that the queue(3) structures are declared; don't assume that
the type argument to *_HEAD and *_ENTRY is a struct.

ab7a87c594 - Point the right bits at the new location of the bus front ends.
The 'bt' SCSI driver now lives in sys/dev/buslogic.

- Correct a few comments.

d31d6be6f6 Implement an EISA new-bus framework. The old driver probe mechanism
had a quirk that made a shim rather hard to implement properly and it was
just easier to convert the drivers in one go.  The changes to the
buslogic driver go beyond just this - the whole driver was new-bus'ed
including pci and isa.  I have only tested the EISA part of this so far.

bc169999cf Improve bt_cmd() so that it has a better chance of working when there
are pending I/O transactions.  It is not clear that is works 100% of
the time under SMP, but since the bt_cmds() that are sent after other
CPUs are started are not critical, the driver will function until I
can figure out why this is the case.

984e3d8eed Add bt_port_probe() a routine shared by the EISA and ISA probe code to
determine IRQ and DRQ information.

Fix a bug that would cause us to attempt to retrieve extended sync
rate information on cards/firmware revs that do not support that command.

0fcabcf90e Do not disable the ISA compatibility window if it is the same value as
that set for our PCI IO address space.  This can happen on the BT-946.
