split device_t/softc for all remaining drivers.
replace "struct device *" with "device_t".
use device_xname(), device_unit(), etc.

Use "struct scsipi_command" in internal command structures so that
we have enough space for 16-byte CDBs.

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22364, verified by myself.

DMA, not dma nor Dma.

Use PAGE_SIZE rather than NBPG.

Eliminate commons. (including a few unused or mismatched ones).

- ANSIfy
- remove some trailing spaces/tabs
- minor style nits

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

branches: 1.15.6;
New callout mechanism with two major improvements over the old
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
resource allocation.
- Insertion and removal of callouts is constant time, important as
this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.

branches: 1.14.10;
Adapt to the new scsipi_adapter interface.

Prepare for support of Apollo-cpuboard-reworked A3000 mainboard SCSI.

branches: 1.12.4;
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.

branches: 1.11.10; 1.11.12;
- Cleanup for -Wall and -Wstrict-prototypes
- Added support for multiple floppy drives
- CyberVision64:
- has now a real console mode
- another bugfix for boards with the new S3 chip
- Ariadne:
- fixed crashes with aeput (mbuf failure)

minphys() functions really should return void.

update SCSI minphys routines' definitions to match standard minphys()
definition and usage.

Many changes from osymh@gemini.oscs.montana.edu (Michael L. Hitch)
Now use amiga HW for soft interrupts, non-contig options (2 or many chunks),
interrupt handler lists, 4066 ethernet, 1291 scsi, option to defer level 6
interrupts to level 4 (deal with icky built-in serial port)

catchup with scsi changes from osymh@gemini.oscs.montana.edu (Michael L. Hitch)

new RCS ID format.

don't flush cache on context switches for 040's, reduce flushing
on dma operations. code from me and Michael Hitch

resistance is futile, you will be assimilated.
amiga goes: config.new *and* /sys/scsi.
clock code coerced into a single .c file adding an accurate usec delay().
disklabel.c updated to DTRT, code to write RDB's to be added soon.
sbic (old scsi) converted over to new scsi and config this covers about
90% of users. Other drivers soon.
