 1.37  14-Jul-2016  msaitoh KNF. No functional change.
 1.36  18-Oct-2014  snj branches: 1.36.2;
src is too big these days to tolerate superfluous apostrophes. It's
"its", people!
 1.35  27-Oct-2012  chs split device_t/softc for all remaining drivers.
replace "struct device *" with "device_t".
use device_xname(), device_unit(), etc.
 1.34  12-May-2009  cegger branches: 1.34.12; 1.34.22;
struct device * -> device_t, no functional changes intended.
 1.33  12-May-2009  cegger struct cfdata * -> cfdata_t, no functional changes intended.
 1.32  28-Apr-2008  martin branches: 1.32.14;
Remove clause 3 and 4 from TNF licenses
 1.31  08-Apr-2008  cegger branches: 1.31.2; 1.31.4;
use aprint_*_dev and device_xname
 1.30  19-Oct-2007  ad branches: 1.30.16;
machine/{bus,cpu,intr}.h -> sys/{bus,cpu,intr}.h
 1.29  16-Nov-2006  christos branches: 1.29.8; 1.29.22; 1.29.24; 1.29.28;
__unused removal on arguments; approved by core.
 1.28  12-Oct-2006  christos - sprinkle __unused on function decls.
- fix a couple of unused bugs
- no more -Wno-unused for i386
 1.27  11-Dec-2005  christos branches: 1.27.20; 1.27.22;
merge ktrace-lwp.
 1.26  04-Feb-2005  perry branches: 1.26.6;
de-__P
 1.25  14-Sep-2004  drochner branches: 1.25.4; 1.25.6;
Separate the namespace for default (ie unspecified) locators used
by the isa.c bus driver and the "address/whatever not specified"
argument passed to leaf device drivers.
The former is "ISACF_XXX_DEFAULT" as generaterd by config(8), the latter
"ISA_UNKNOWN_XXX", defined in isavar.h.
This way we save a dependency of every ISA device driver on "locators.h".
 1.24  02-Oct-2002  thorpej branches: 1.24.6;
Fix sizeof and whitespace bug from the script I'm using to do the
CFATTACH_DECL conversion. (Grumble.)
 1.23  02-Oct-2002  thorpej Use CFATTACH_DECL().
 1.22  27-Sep-2002  thorpej Declare all cfattach structures const.
 1.21  07-Jan-2002  thorpej Overhaul of the ISA autoconfiguration code to support direct
configuration of devices logically attached to the ISA bus:

* Change the isa_attach_args to have arrays of io, mem, irq, drq
resources.
* Add a "pnpnames" and a linked list of "pnpcompatnames" to the
isa_attach_args. If either of these members are non-NULL,
direct configuration of the bus is being performed. Add an
ISA_DIRECT_CONFIG() macro to test for this.
* Drivers are not allowed to modify the isa_attach_args unless
direct configuration is not being performed and the probe fucntion
is returning success.
* Adapt device drivers -- currently, all driver probe routines return
"no match" if ISA_DIRECT_CONFIG() evaluates to true.
 1.20  15-Nov-2001  lukem don't need <sys/types.h> when including <sys/param.h>
 1.19  13-Nov-2001  lukem add RCSID
 1.18  03-May-2001  ross branches: 1.18.2;
Split pci and eisa/isa attachment calls, plus misc cleanup.
 1.17  25-Apr-2001  bouyer Pull up the thorpej_scsipi branch to main branch.
This is a completely rewritten scsipi_xfer execution engine, and the
associated changes to HBA drivers. Overview of changes & features:
- All xfers are queued in the mid-layer, rather than doing so in an
ad-hoc fashion in individual adapter drivers.
- Adapter/channel resource management in the mid-layer, avoids even trying
to start running an xfer if the adapter/channel doesn't have the resources.
- Better communication between the mid-layer and the adapters.
- Asynchronous event notification mechanism from adapter to mid-layer and
peripherals.
- Better peripheral queue management: freeze/thaw, sorted requeueing during
recovery, etc.
- Clean separation of peripherals, adapters, and adapter channels (no more
scsipi_link).
- Kernel thread for each scsipi_channel makes error recovery much easier
(no more dealing with interrupt context when recovering from an error).
- Mid-layer support for tagged queueing: commands can have the tag type
set explicitly, tag IDs are allocated in the mid-layer (thus eliminating
the need to use buggy tag ID allocation schemes in many adapter drivers).
- support for QUEUE FULL and CHECK CONDITION status in mid-layer; the command
will be requeued, or a REQUEST SENSE will be sent as appropriate.

Just before the merge syssrc has been tagged with thorpej_scsipi_beforemerge
 1.16  03-Oct-2000  simonb branches: 1.16.2;
Revert rev 1.31 of bha.c (and associtated changes in the headers and
config glue files).

Fixes PR kern/9841. Tested by Tracy J. Di Marco White with a bt948
and 6 disks.
 1.15  01-Oct-1999  thorpej branches: 1.15.2; 1.15.12;
Fix compilation of ISA bha front-end. PR #8528, Takahiro Kambe.
 1.14  15-Aug-1998  mycroft Assign my copyrights to TNF.
 1.13  25-Jun-1998  thorpej Don't panic if a DRQ is already allocated. Instead, just return EAGAIN
to indicate that the resource is unavailable.
 1.12  09-Jun-1998  thorpej Nuke __BROKEN_INDIRECT_CONFIG.
 1.11  09-Jun-1998  thorpej Adjust for changes to the ISA DMA API.
 1.10  20-Oct-1997  thorpej Don't panic if we fail to remap i/o or mem space in the attach function.
Instead, print a diagnostic and return. (Some drivers do this already.)

Also, normalize the diagnostic message, and fix some places where the
printfs were getting ugly.
 1.9  19-Oct-1997  thorpej Make sure the i/o and/or mem addresses aren't wildcarded (i.e. -1) before
using the address in a bus_space_map() call.
 1.8  27-Aug-1997  bouyer Merge scsipi branch in the mainline. This add support for ATAPI devices
(currently only CD-ROM drives on i386). The sys/dev/scsipi system provides 2
busses to which devices can attach (scsibus and atapibus). This needed to
change some include files and structure names in the low level scsi drivers.
 1.7  06-Jun-1997  thorpej branches: 1.7.2; 1.7.4;
Pull thorpej-bus-dma branch into mainline.
 1.6  28-Mar-1997  mycroft branches: 1.6.2;
Use a temporary data structure for holding probe information, rather than a
full softc.
 1.5  21-Oct-1996  thorpej New bus.h implementation/interface:
- No more distinction between i/o-mapped and memory-mapped
devices. It's all "bus space" now, and space tags
differentiate the space with finer grain than the
bus chipset tag.
- Add memory barrier methods.
- Implement space alloc/free methods.
- Implement region read/write methods (like memcpy to/from
bus space).
This interface provides a better abstraction for dealing with
machine-independent chipset drivers.
 1.4  13-Oct-1996  christos backout kprintf changes
 1.3  10-Oct-1996  christos - printf -> kprintf, sprintf -> ksprintf
- Remove unused variable
- include <systm.h>
 1.2  01-Sep-1996  mycroft Minor changes.
 1.1  31-Aug-1996  mycroft Split the BusLogic driver apart, and rename it to `bha (like BSDi).
 1.6.2.2  18-May-1997  thorpej Do the __BROKEN_INDIRECT_CONFIG dance.
 1.6.2.1  13-May-1997  thorpej - Stash the bus dma tag and bus-specific DMA flags in the softc.
- Adapt to new software interface to the on-board ISA DMA controller.
- Detect buggy VLB variants of this card. Buggy cards get 24-bit
ISA DMA, working cards (rev. 3.37 and higher) get to use 32-bit DMA.
 1.7.4.1  27-Aug-1997  thorpej Update marc-pcmcia branch from trunk.
 1.7.2.1  01-Jul-1997  bouyer Updates for new scsipi subsystem. Actally known to work on i386 and sparc.
 1.15.12.1  04-Oct-2000  simonb Pull up rev 1.16 (approved by thorpej):
Revert rev 1.31 of bha.c (and associtated changes in the headers and
config glue files).

Fixes PR kern/9841. Tested by Tracy J. Di Marco White with a bt948
and 6 disks.
 1.15.2.2  27-Mar-2001  bouyer Convert these drivers to thorpej_scsipi (untested).
 1.15.2.1  20-Nov-2000  bouyer Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.
