 1.9  03-Mar-2022  riastradh arm: Use device_set_private for various drivers.
 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  26-Mar-2014  matt branches: 1.6.44;
Allow SRAB to be optional.
 1.5  17-Dec-2013  joerg branches: 1.5.2;
Mark bcmrng_write_4, bcmccb_write_4 and bcmccb_read_4 as unused
 1.4  28-Oct-2013  matt Add support for the BCM56340 iProc based switch
 1.3  03-Oct-2012  matt branches: 1.3.2; 1.3.4; 1.3.6;
Add code to init the SRAB (the switch robot). Don't configure eth3 by default.

 1.1  01-Sep-2012  matt branches: 1.1.2;
Add initial device support for the Broadcom BCM5301x family.
 1.1.2.2  20-Aug-2014  tls Rebase to HEAD as of a few days ago.
 1.1.2.1  20-Nov-2012  tls Resync to 2012-11-19 00:00:00 UTC
 1.3.6.1  18-May-2014  rmind sync with head
 1.3.4.2  28-Nov-2012  matt Merge improved arm support (especially Cortex) from HEAD
including OMAP and BCM53xx support.
 1.3.4.1  03-Oct-2012  matt file bcm53xx_ccb.c was added on branch matt-nb6-plus on 2012-11-28 22:40:22 +0000
 1.3.2.3  22-May-2014  yamt sync with head.

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")
 1.3.2.2  30-Oct-2012  yamt sync with head
 1.3.2.1  03-Oct-2012  yamt file bcm53xx_ccb.c was added on branch yamt-pagecache on 2012-10-30 17:18:59 +0000
 1.5.2.3  26-Mar-2014  matt Allow SRAB to be optional
 1.5.2.2  15-Feb-2014  matt Merge armv7 support from HEAD, specifically support for the BCM5301X
and BCM56340 evbarm kernels.
 1.5.2.1  17-Dec-2013  matt file bcm53xx_ccb.c was added on branch matt-nb5-mips64 on 2014-02-15 16:18:36 +0000
 1.6.44.3  03-Apr-2021  thorpej Give config_attach() the tagged variadic argument treatment and
mechanically convert all call sites.
 1.6.44.2  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.
 1.6.44.1  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.
 1.7.8.1  04-Aug-2021  thorpej Adapt to CFARGS().
