 1.19  07-Aug-2021  thorpej Merge thorpej-cfargs2.
 1.18  04-Jul-2021  thorpej branches: 1.18.2;
Remove unnecessary #include <sys/malloc.h>
 1.17  24-Apr-2021  thorpej branches: 1.17.2;
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?).
 1.16  14-Jun-2011  matt branches: 1.16.68;
Major cleanup of alpha device drivers.
Switch to CFATTACH_DECL_NEW.
struct device * -> device_t
struct cfdata * -> cfdata_t
Use of device_xname. No direct access to struct device members.
Use aprint* (not complete).
 1.15  14-Mar-2009  dsl branches: 1.15.10;
Change about 4500 of the K&R function definitions to ANSI ones.
There are still about 1600 left, but they have ',' or /* ... */
in the actual variable definitions - which my awk script doesn't handle.
There are also many that need () -> (void).
(The script does handle misordered arguments.)
 1.14  14-Mar-2009  dsl Remove all the __P() from sys (excluding sys/dist)
Diff checked with grep and MK1 eyeball.
i386 and amd64 GENERIC and sys still build.
 1.13  04-Mar-2007  christos branches: 1.13.44; 1.13.52; 1.13.58;
Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
 1.12  01-Jan-2003  thorpej branches: 1.12.18; 1.12.56;
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  14-May-1998  thorpej branches: 1.9.26; 1.9.28;
Garbage-collect the old confargs stuff that was used in the Early Days.
It isn't really appropriate anymore. Replace it with a real mainbus
attach args structure.
 1.8  13-May-1998  thorpej Clean up a buglet.
 1.7  12-Jan-1998  thorpej Adjust for config changes.
 1.6  02-Sep-1997  thorpej Nuke the idea of <machine/options.h>. It completely defeats the purpose
of fine-grain option dependencies.
 1.5  08-Jun-1997  thorpej branches: 1.5.4; 1.5.6;
Print the hose number in kftprint().
 1.4  07-Apr-1997  cgd branches: 1.4.2;
by default, provide RCS IDs for NetBSD/alpha kernel files in kernel binaries.
This can be disabled (to save a bit of space) with the NO_KERNEL_RCSIDS
options, which is present but commented out in the ALPHA config file.
In ELF-format kernels, these strings are present in the kernel binary but
are not loaded into memory. (In ECOFF-format kernels, there's no easy way
to keep them from being loaded, so they _are_ loaded into memory.)
 1.3  06-Apr-1997  cgd clean up NetBSD RCS ID strings, include machine/options.h
 1.2  12-Mar-1997  cgd Copyright notice consistency, per Matthew Jacob.
 1.1  12-Mar-1997  cgd AlphaServer 8200 & 8400 support, including CPU specific details, TurboLaser
system bus support, and KFTxx support. From Matthew Jacob, NASA Ames
Research Center.
 1.4.2.2  22-Jul-1997  cgd sync nwscons branch with changes in -current as of July 21, 1997
 1.4.2.1  01-Jun-1997  cgd sync the nwscons branch up with yesterday's version of the trunk.
Lots of conflicts/changes because of the RCS Id format changes.
Also, a few cleanups and corrections.
 1.5.6.2  08-Jun-1997  thorpej Print the hose number in kftprint().
 1.5.6.1  08-Jun-1997  thorpej file kftxx.c was added on branch alpha-nwscons on 1997-06-08 07:02:46 +0000
 1.5.4.1  04-Sep-1997  thorpej Update marc-pcmcia branch from trunk.
 1.9.28.1  10-Oct-2002  jdolecek sync kqueue with -current; this includes merge of gehenna-devsw branch,
merge of i386 MP branch, and part of autoconf rototil work
 1.9.26.2  03-Jan-2003  thorpej Sync with HEAD.
 1.9.26.1  18-Oct-2002  nathanw Catch up to -current.
 1.12.56.1  12-Mar-2007  rmind Sync with HEAD.
 1.12.18.1  03-Sep-2007  yamt sync with head.
 1.13.58.1  13-May-2009  jym Sync with HEAD.

Commit is split, to avoid a "too many arguments" protocol error.
 1.13.52.1  28-Apr-2009  skrll Sync with HEAD.
 1.13.44.1  04-May-2009  yamt sync with head.
 1.15.10.1  23-Jun-2011  cherry Catchup with rmind-uvmplock merge.
 1.16.68.1  21-Mar-2021  thorpej Give config_found() the same variadic arguments treatment as
config_search(). This commit only adds the CFARG_EOL sentinel
to the existing config_found() calls. Conversion of config_found_sm_loc()
and config_found_ia() call sites will be in subsequent commits.
 1.17.2.1  01-Aug-2021  thorpej Sync with HEAD.
 1.18.2.1  03-Aug-2021  thorpej Adapt to CFARGS().
