 1.10  04-Oct-2025  thorpej Use device_{get,set}prop_bool() for "is_console".
 1.9  24-Sep-2023  andvar define i variable in for loop.
valkyriefb_attach() doesn't have one defined in the function scope.

fixes VALKYRIEFB_DEBUG enabled build for macppc.
 1.8  16-Feb-2022  riastradh powerpc: Sprinkle "memory" clobbers on eieio and nearby asm blocks.

Otherwise the compiler may reorder these around loads and stores,
which mostly defeats the purpose. `asm volatile' just ensures the
instruction isn't _deleted_; it may still move around.
 1.7  07-Aug-2021  thorpej Merge thorpej-cfargs2.
 1.6  24-Apr-2021  thorpej branches: 1.6.8;
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?).

 1.4  06-Jul-2016  macallan shut up another unused function warning
 1.3  19-Feb-2014  macallan branches: 1.3.6;
- don't read beyond array bounds
- break a bunch of long lines
- remove an outdated comment
 1.2  23-May-2012  macallan branches: 1.2.2; 1.2.4;
cleanup, remove debug goo
 1.1  24-Jan-2012  macallan branches: 1.1.4; 1.1.6;

 1.1.6.4  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")
 1.1.6.3  30-Oct-2012  yamt sync with head
 1.1.6.2  17-Apr-2012  yamt sync with head
 1.1.6.1  24-Jan-2012  yamt file valkyriefb.c was added on branch yamt-pagecache on 2012-04-17 00:06:37 +0000
 1.1.4.3  02-Jun-2012  mrg sync to latest -current.
 1.1.4.2  18-Feb-2012  mrg merge to -current.
 1.1.4.1  24-Jan-2012  mrg file valkyriefb.c was added on branch jmcneill-usbmp on 2012-02-18 07:32:35 +0000
 1.2.4.1  18-May-2014  rmind sync with head
 1.2.2.2  03-Dec-2017  jdolecek update from HEAD
 1.2.2.1  20-Aug-2014  tls Rebase to HEAD as of a few days ago.
 1.3.6.1  09-Jul-2016  skrll Sync with HEAD
 1.5.18.1  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.
 1.6.8.1  04-Aug-2021  thorpej Adapt to CFARGS().
