 1.22  07-Aug-2021  thorpej Merge thorpej-cfargs2.
 1.21  24-Apr-2021  thorpej branches: 1.21.8;
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?).
 1.20  25-Oct-2014  skrll branches: 1.20.34;
Remove katelib.h and references to it.

{Read,Write}{Word,Byte} macros are provided in the files that still use
them. Someone(tm) should convert them to bus_space(9)
 1.19  21-Jan-2014  christos fix unused variable
 1.18  27-Oct-2012  chs branches: 1.18.2;
split device_t/softc for all remaining drivers.
replace "struct device *" with "device_t".
use device_xname(), device_unit(), etc.
 1.17  03-Jun-2011  matt branches: 1.17.2; 1.17.12;
device_t, cfdata_t, device_private, device_xname cleanup
CFATTACH_DECL_NEW for struct device only devices
bump SYMTAB_SPACE for EB7500ATX
 1.16  12-May-2009  cegger branches: 1.16.4; 1.16.6; 1.16.10;
use device_xname()
 1.15  14-Mar-2009  dsl ANSIfy another 1261 function definitions.
The only ones left in sys are beyond by sed script!
(or in sys/dist or sys/external)
Mostly they have function pointer parameters.
 1.14  14-Mar-2009  dsl 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.)
 1.13  11-Dec-2005  christos branches: 1.13.80; 1.13.88; 1.13.94;
merge ktrace-lwp.
 1.12  14-Jul-2003  lukem use __KERNEL_RCSID() in a consistent manner
 1.11  01-Apr-2003  thorpej branches: 1.11.2;
Use PAGE_SIZE rather than NBPG.
 1.10  05-Oct-2002  chs add missing protos, clean up includes.
 1.9  02-Oct-2002  thorpej Fix script-o's in previous.
 1.8  02-Oct-2002  thorpej Use CFATTACH_DECL().
 1.7  27-Sep-2002  thorpej Declare all cfattach structures const.
 1.6  27-Sep-2002  provos remove trailing \n in panic(). approved perry.
 1.5  05-Aug-2002  bjh21 Rather than forcing on XS_POLL in SCSI transfers ourselves, set
SCSIPI_ADAPT_POLL_ONLY to tell the MI scsipi layer to do it for us. This,
plus G/Cing some debugging code, removes the card-specific scsi_request
wrappers.
 1.4  22-May-2002  bjh21 Substantial overhaul of podule IDs. Unlike on PCI or USB, podule IDs are
assigned by RISCOS Ltd (and were assigned by Acorn) to be unique across all
manufacturers. This means that associating each one with a manufacturer (and
checking the manufacturer when attaching) is bogus. Thus, we don't do that
any more.

This should have the pleasant side-effect of getting APDL IDE interfaces
working, since they're just ICS ones with a different manufacturer ID.
 1.3  27-Nov-2001  thorpej branches: 1.3.2; 1.3.10; 1.3.12;
Use <machine/intr.h>, not <machine/irqhandler.h>
 1.2  22-Nov-2001  thorpej Kill <machine/katelib.h>. Any place that still uses it should just
reference <arm/arm32/katelib.h> until such time as all use of this
file has been purged from the face of the earth.
 1.1  05-Oct-2001  reinoud branches: 1.1.4;
Initial commit of the splitting off of arch/acorn32 from arch/arm32.

The IOMD/VIDC combination is now moved to arch/arm/iomd together. These
files still need a lot of cleaning up :( .... esp. the RC7500 support that
is still dormant in it; this needs either to be removed or split out for
RC7500's ``VIDC'' video/audio variant.

Apart from the RC7500 support wich is still in arch/arm32 the
iomd,vidc,riscpc and podulebus subdirectories of arch/arm32 can be removed.

This split still uses some small parts of arch/arm32 .... those are the MI
parts that haven't been moved yet.

RiscPC/A7000 have been tested and confirmed to build as should NC.

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")
 1.17.2.1  30-Oct-2012  yamt sync with head
 1.18.2.1  18-May-2014  rmind sync with head
 1.20.34.1  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.
 1.21.8.1  03-Aug-2021  thorpej Adapt to CFARGS().
