Keyword substitution: kv
Default branch: MAIN

TAB/space/indent cleanup.

fix typos in comments, mainly basicly -> basically.

sync with head

Another failed typedef fixed.

Sync with HEAD.

Sync with HEAD.

Update haad-dm branch to haad-dm-base2.

Split device_t/softc.  Use aprint*() and device_xname().
Not tested. I don't have its hardware and no response in port-x68k.

Sync with HEAD.

Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.

merge ktrace-lwp.

Sync with HEAD.

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

Catch up to -current.

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.

Convert to thorpej_scsipi (untested).

Use bus_dma(9) for DMA bouncing.
The code is dirty.  It should be rewritten in the future.

Merged minoura_x68k_bus_h branch.

scsirom driver to probe CZ-6BS1-clone and Mach-2 SCSI host adaptor board
itself.
Modifications to spc and mha drivers.
NOTE: mha is not fully bus.h'fied.

Adapt to the new scsipi_adapter interface.

Support of MK-HA1 Mach-2 SCSI adaptor.
