RevisionDateAuthorComments
 1.16  01-Jan-2022  andvar fix typos in comments, mainly basicly -> basically.
 1.15  12-Nov-2009  dyoung Remove definition of spc_activate(), it has gone away.
 1.14  12-Nov-2009  dyoung Remove superfluous activation hook.

Add a child-detachment hook.
 1.13  12-May-2009  cegger struct device * -> device_t, no functional changes intended.
 1.12  04-May-2008  martin branches: 1.12.14;
Move to standard TNF 2 clause license
 1.11  31-Mar-2008  tsutsui branches: 1.11.2; 1.11.4;
Split softc/device_t for spc(4) and misc related cleanup.
 1.10  11-Dec-2005  christos branches: 1.10.70;
merge ktrace-lwp.
 1.9  07-Dec-2004  thorpej Use "struct scsipi_command" in internal command structures so that
we have enough space for 16-byte CDBs.
 1.8  25-Sep-2004  tsutsui Use ANSI function decls.
 1.7  09-Aug-2004  mycroft Add detach support for spc@pcmcia, modeled after aic@pcmcia.
 1.6  02-Aug-2003  tsutsui TAB/space cosmetics
 1.5  01-Aug-2003  tsutsui - Add hooks for MD DMA transfers.
- Prepare ADAPTER_REQ_SET_XFER_MODE function.
(currently sync xfer is not supported)
 1.4  05-Jul-2003  tsutsui Rename some MI mb89352 functions for consistency:
spcintr() -> spc_intr()
spcattach() -> spc_attach()
 1.3  25-Apr-2001  bouyer branches: 1.3.22;
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
 1.2  07-Jan-2000  nisimura branches: 1.2.6;
Remove tinfo_t symbols which result in never used global common variables.
 1.1  13-Feb-1999  minoura branches: 1.1.8;
MI version of the Fujitsu MB89352 SCSI Protocol Controler (SPC) driver.
Based on experimental NetBSD/pc98 ISA/PISA version, which was derived
from the MD /sys/arch/x68k/dev/spc.c.
 1.1.8.2  27-Mar-2001  bouyer Convert these drivers to thorpej_scsipi (untested).
 1.1.8.1  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.
 1.2.6.1  21-Jun-2001  nathanw Catch up to -current.
 1.3.22.6  18-Dec-2004  skrll Sync with HEAD.
 1.3.22.5  19-Oct-2004  skrll Sync with HEAD
 1.3.22.4  21-Sep-2004  skrll Fix the sync with head I botched.
 1.3.22.3  18-Sep-2004  skrll Sync with HEAD.
 1.3.22.2  12-Aug-2004  skrll Sync with HEAD.
 1.3.22.1  03-Aug-2004  skrll Sync with HEAD
 1.10.70.2  02-Jun-2008  mjf Sync with HEAD.

 1.12.14.1  13-May-2009  jym Sync with HEAD.

Commit is split, to avoid a "too many arguments" protocol error.
