 1.23  07-Aug-2021  thorpej Merge thorpej-cfargs2.
 1.22  24-Apr-2021  thorpej branches: 1.22.8;
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?).

malloc(9) -> kmem(9)
 1.20  10-Nov-2019  chs branches: 1.20.8;
in many device attach paths, allocate memory with M_WAITOK instead of M_NOWAIT
and remove code to handle failures that can no longer happen.

 1.16  26-Aug-2005  drochner s/locdesc_t/int/g
 1.15  30-Jun-2005  drochner branches: 1.15.2;
adaptions to config_search() change, and minor autoconf fixes, mostly from Havard Eidnes

- ANSI function decls
- remove __P()
- u_intNN_t -> uintNN_t
- remove register decls
- bcopy -> memcpy, strcpy
- bzero -> memset
- bcmp -> memcmp
- use malloc(9) with M_ZERO
- some KNF
etc.
 1.13  15-Jul-2003  lukem branches: 1.13.8; 1.13.10;
__KERNEL_RCSID()
 1.12  10-May-2003  tsutsui branches: 1.12.2;
- Prepare common structures for interrupt handler and share them between
Hyper-bus and AP-bus.
- Use LIST rather than static array for interrupt dispatcher.
 1.11  09-May-2003  tsutsui - Define and use struct hb_attach_args rather than struct confargs
for hb devices.
- Move declarations for hb functions and macros to dev/hbvar.h.
- Define and use hb_badaddr() macro for hb devices.
- Declare news3400_badaddr() in machine/cpu.h rather than machine/autoconf.h.
- Remove unused stuff from machine/autoconf.h.
 1.10  01-Jan-2003  thorpej Use aprint_normal() for cfprint routines.
 1.9  02-Oct-2002  thorpej Use CFATTACH_DECL().
 1.8  27-Sep-2002  thorpej Declare all cfattach structures const.
 1.7  27-Sep-2002  thorpej Introduce a new routine, config_match(), which invokes the
cfattach->ca_match function in behalf of the caller. Use it
rather than invoking cfattach->ca_match directly.
 1.6  27-Sep-2002  thorpej Rather than referencing the cfdriver directly in the cfdata entries,
instead use a string naming the driver. The cfdriver is then looked
up in a list which is built at run-time.
 1.5  03-Dec-2000  matt branches: 1.5.4; 1.5.8;
Make this stuff compile with -wstrict-prototpes -wmissing-prototypes.
More use of prototypes inside includes should be done.
 1.4  17-Dec-1999  tsubai Implement hb_intr_establish().
 1.3  11-Jul-1999  tsubai branches: 1.3.2; 1.3.8;
Cleanup.
 1.2  05-Jun-1998  tsubai branches: 1.2.10;
Add support for NWB-231A 4-port RS-232C card.
 1.1  18-Feb-1998  tsubai Initial import of NetBSD/news.
 1.2.10.1  02-Aug-1999  thorpej Update from trunk.
 1.3.8.1  27-Dec-1999  wrstuden Pull up to last week's -current.
 1.3.2.2  08-Dec-2000  bouyer Sync with HEAD.
 1.3.2.1  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.
 1.5.8.2  03-Jan-2003  thorpej Sync with HEAD.
 1.5.8.1  18-Oct-2002  nathanw Catch up to -current.

merge of i386 MP branch, and part of autoconf rototil work
 1.12.2.5  10-Nov-2005  skrll Sync with HEAD. Here we go again...

 1.18.26.1  05-Mar-2011  rmind sync with head
 1.18.22.1  29-Dec-2010  matt Adapt to the new interrupt framework.
Use mips_set_wbflush instead of playing preprocessor games.
 1.19.56.1  13-Apr-2020  martin Mostly merge changes from HEAD upto 20200411
 1.20.8.1  14-Dec-2020  thorpej Sync w/ HEAD.
 1.21.2.6  05-Apr-2021  thorpej Treat config_probe() as if it were a boolean function; don't compare
return value > 0... except for the odd balls, which are now really easy
to spot.
 1.21.2.5  05-Apr-2021  thorpej config_match() -> config_probe() for the straight-forward indirect config
cases. There are still a few odd balls using config_match() which should
be sorted out later.
 1.21.2.4  04-Apr-2021  thorpej CFARG_SUBMATCH -> CFARG_SEARCH for the indirect configuration uses.
 1.21.2.3  03-Apr-2021  thorpej Give config_attach() the tagged variadic argument treatment and
mechanically convert all call sites.
 1.21.2.2  21-Mar-2021  thorpej CFARG_IATTR usage audit:

If a device carries only one interface attribute, there is no need
to specify it when calling config_search(); that specification is
meant only to disambiguate which interface attribute (which is a
proxy for "what kind of attach args are being used") is having
children attached. cfparent_match() will take care of ensuring that
any potential children can attach to one of the parent's iterface
attributes, and if the parent only carries one, no disambiguation is
necessary.
 1.21.2.1  20-Mar-2021  thorpej The proliferation if config_search_*() and config_found_*() combinations
is a little absurd, so begin to tidy this up:

- Introduce a new cfarg_t enumerated type, that defines the types of
tag-value variadic arguments that can be passed to the various
config_*() functions (CFARG_SUBMATCH, CFARG_IATTR, and CFARG_LOCATORS,
for now, plus a CFARG_EOL sentinel).
- Collapse config_search_*() into config_search() that takes these
variadic arguments.
- Convert all call sites of config_search_*() to the new signature.
Noticed several incorrect usages along the way, which will be
audited in a future commit.
 1.22.8.1  04-Aug-2021  thorpej Adapt to CFARGS().
