 1.55  24-Apr-2021  thorpej branches: 1.55.8;
Merge thorpej-cfargs branch:

Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.

Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is
in play, and allowing for future change in semantics. (As of now,
this is just a wrapper around config_match(), but that is an
implementation detail.)

Remove unnecessary or redundant interface attributes where they're not
needed.

There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)

...and a sentinel value CFARG_EOL.

Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.

Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance. This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).

Chuck Silvers' patch posted current-users and tech-kern:
http://mail-index.netbsd.org/current-users/2012/10/09/msg021233.html

Should be pulled up to netbsd-6.
 1.52  23-Nov-2009  rmind branches: 1.52.12; 1.52.18; 1.52.22;
Use lwp_getpcb() on m68k ports, clean from struct user usage.
 1.51  18-Dec-2008  isaki Sync with other m68k ports.
- Remove PHYS_IODEV, PHYS_INTIODEV. These are real copy of INTIOBASE.

 1.50  05-Dec-2008  isaki Use TAILQ_* macros.
 1.49  29-Nov-2008  isaki Split device_t/softc. Use aprint*() and device_xname().
Not tested. I don't have its hardware and no response in port-x68k.

Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.
 1.45  12-May-2007  isaki branches: 1.45.10;
Clean up white spaces and tabs.
 1.44  11-Mar-2007  isaki branches: 1.44.2; 1.44.8;

 1.38  26-Nov-2005  tsutsui Fix typo (FALLTHOUGH -> FALLTHROUGH). From Jeff Ito.
 1.37  13-Jun-2005  he branches: 1.37.2; 1.37.8;
Change the signature of badaddr() and badbaddr() from taking a caddr_t
to taking a volatile void*. This gets rid of a number of casts to make
this compile under -Wcast-qual.
Add some volatiles and consts in other places to make this build under
-Wcast-qual.
Also rename a few variables to make this build under -Wshadow.
Also get rid of duplicated declarations of badaddr() and badbaddr()
in machdep.c, they're already there from <machine/cpu.h>.
 1.36  21-Feb-2005  thorpej Part 1 of a cleanup pass over the SCSI subsystem. The aim is to name
everything "scsi_*", since we really are talking about the SCSI command
set, ATAPI transport not withstanding. Improve the names of many structures,
and prepend "SCSI_" onto all SCSI command opcodes. Place items described
by the SCSI Primary Commands document into scsi_spc.h.

 1.26  19-Dec-2001  minoura Implement bus_dmamap_sync properly.

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
 1.21  16-Jun-2000  minoura branches: 1.21.4;
Print newline while attach.
 1.20  30-Apr-2000  minoura branches: 1.20.2;
Revert 1.18 change.
Hopefully this is a temporary fix; something might be missing in
the SCSI negotiation.
 1.19  23-Mar-2000  thorpej 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.
 1.18  18-Nov-1999  minoura Do not reset SCSI bus.
 1.17  30-Sep-1999  thorpej branches: 1.17.2; 1.17.8;

 1.15  24-Mar-1999  minoura branches: 1.15.2;
Shut up gcc -Wall.
 1.14  22-Mar-1999  minoura Use bus_dma(9) for DMA bouncing.
The code is dirty. It should be rewritten in the future.
 1.13  16-Mar-1999  minoura Merged minoura_x68k_bus_h branch.
 1.12  07-Feb-1999  minoura Issue SCSI reset on initialize.
Clean unused mha_reset.
 1.11  05-Dec-1998  mjacob branches: 1.11.4;
Update HBAs to incorporate the new max_lun property.
 1.10  19-Nov-1998  thorpej Adapt to the new scsipi_adapter interface.
 1.9  10-Oct-1998  thorpej Garbage-collect the open_target_lu and close_target_lu entry points from
struct scsipi_adapter; they were not used.

Add a scsipi_ioctl entry point to struct scsipi_adapter. This will be
used to issue ioctl commands to the host adapters.

Inspired by PR #6090, from Matt Jacob.
 1.8  09-Sep-1998  minoura Make device probe/attach sessions to be executed at splhigh.
mha driver used interrupt driven I/O.
