 1.8  07-Aug-2021  thorpej Merge thorpej-cfargs2.
 1.7  24-Apr-2021  thorpej branches: 1.7.8;
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?).
 1.6  01-Jul-2011  dyoung branches: 1.6.68;
#include <sys/bus.h> instead of <machine/bus.h>.
 1.5  18-Jun-2011  matt struct device * -> device_t
struct cfdata * -> cfdata_t
use device accessors, use device_private.
some softc/device_t splits (macppc needs a bunch more)
aprint*_dev used considerably more
 1.4  05-Jun-2011  matt struct device * -> device_t, struct cfdata * -> cfdata_t
CFATTACH_DECL(*, sizeof(struct device), -> CFATTACH_DECL_NEW(&, 0
 1.3  28-Apr-2008  martin branches: 1.3.22; 1.3.28; 1.3.32;
Remove clause 3 and 4 from TNF licenses
 1.2  17-Oct-2007  garbled branches: 1.2.2; 1.2.4; 1.2.8; 1.2.22; 1.2.24; 1.2.26;
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.

 1.1.6.1  02-Nov-2007  joerg More diff reduce to HEAD due to botched up merging.
 1.1.2.1  08-May-2007  garbled Move pmppc over to evbppc. (previous location sys/arch/pmppc)
 1.2.26.1  16-May-2008  yamt sync with head.
 1.2.24.1  18-May-2008  yamt sync with head.

 1.3.32.1  23-Jun-2011  cherry Catchup with rmind-uvmplock merge.
 1.3.28.1  06-Jun-2011  jruoho Sync with HEAD.
 1.3.22.1  12-Jun-2011  rmind sync with head
 1.6.68.3  22-Mar-2021  thorpej Audit CFARG_IATTR in config_found() calls, and remove it in situations
where the interface attribute is not ambiguous.
 1.6.68.2  22-Mar-2021  thorpej Mechanical conversion of config_found_sm_loc() -> config_found().
CFARG_IATTR usage needs to be audited.
 1.6.68.1  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.
 1.7.8.1  04-Aug-2021  thorpej Adapt to CFARGS().
