 1.27  21-Jul-2022  andvar fix typos in comments and log messages, mainly s/intrrupt/interrupt/.
 1.26  07-Aug-2021  thorpej Merge thorpej-cfargs2.
 1.25  24-Apr-2021  thorpej branches: 1.25.8;
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?).
 1.24  31-Mar-2017  msaitoh branches: 1.24.28;
Remove extra 0x. This bug was added when replacing bitmask_snprintf(9) with
snprintb(3) (in between NetBSD 5 and 6). Old bitmask_snprint(9) didn't add
0x" automatically for hexadecimal value, so old code used it with "0x%s".
 1.23  29-Mar-2014  christos branches: 1.23.6; 1.23.10; 1.23.14;
make pci_intr_string and eisa_intr_string take a buffer and a length
instead of relying in local static storage.
 1.22  27-Oct-2012  chs branches: 1.22.2;
split device_t/softc for all remaining drivers.
replace "struct device *" with "device_t".
use device_xname(), device_unit(), etc.
 1.21  05-Apr-2009  dholland branches: 1.21.12; 1.21.22;
Fix broken build from missing comma. (HI CHRISTOS!!)
 1.20  16-Dec-2008  christos branches: 1.20.2;
replace bitmask_snprintf(9) with snprintb(3)
 1.19  11-Dec-2005  christos branches: 1.19.74; 1.19.78; 1.19.86;
merge ktrace-lwp.
 1.18  26-Aug-2005  drochner s/locdesc_t/int/g
 1.17  30-Jun-2005  drochner branches: 1.17.2;
adaptions to config_search() change, and minor autoconf fixes, mostly from Havard Eidnes
 1.16  07-Jun-2005  he Sprinkle some const around to make these files compile with -Wcast-qual.
 1.15  24-Apr-2004  kleink Update for new pci_devinfo(9) signature.
 1.14  15-Jul-2003  lukem __KERNEL_RCSID()
 1.13  24-Mar-2003  imp branches: 1.13.2;
It appears that we now need locators.h. Other files in this directory
have it, and adding it makes this compile. If this is not the right
way to fix this problem, please let me know the right way...
 1.12  01-Jan-2003  thorpej Use aprint_normal() for cfprint routines.
 1.11  02-Oct-2002  thorpej Use CFATTACH_DECL().
 1.10  27-Sep-2002  thorpej Declare all cfattach structures const.
 1.9  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.
 1.8  10-Mar-2002  takemura Attached vrpiu at vrc4173bcu.
 1.7  10-Mar-2002  takemura Attached vrkiu at vrc4173bcu.

for a reference, the tree before this commit was tagged
as yamt-pagecache-tag8.

this commit was splitted into small chunks to avoid
a limitation of cvs. ("Protocol error: too many arguments")

 1.24.28.7  05-Apr-2021  thorpej Decorate the problematic config_probe() calls (non-boolean return value)
with XXX.
 1.24.28.6  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.
 1.24.28.5  04-Apr-2021  thorpej CFARG_SUBMATCH -> CFARG_SEARCH for the indirect configuration uses.
 1.24.28.4  03-Apr-2021  thorpej Give config_attach() the tagged variadic argument treatment and
mechanically convert all call sites.
 1.24.28.3  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.
 1.24.28.2  20-Mar-2021  thorpej Don't pass the autoconfig print routine as the aux pointer to the
indirect search routine. That argument slot is meant for "attach
args" structures, not function pointers. Besides, no one actually
used it anyway.
 1.24.28.1  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.
 1.25.8.1  04-Aug-2021  thorpej Adapt to CFARGS().
