 1.7  20-Dec-2023  thorpej Remove unnecessary <sys/malloc.h> include.
 1.6  04-Aug-2023  rin amiga/acafh(4): Appease GCC 12.3.0 -Wmisleading-indentation

No binary changes. Alternatively, pmap_update(9) can be placed in
this loop, but it should make nothing other than small overhead.
 1.5  07-Aug-2021  thorpej Merge thorpej-cfargs2.
 1.4  24-Apr-2021  thorpej branches: 1.4.8;
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?).
 1.3  26-Dec-2013  rkujawa branches: 1.3.4; 1.3.6; 1.3.10; 1.3.50;
Implement the probe procedure for ACA500. Now the user just needs acafh0
compiled in his kernel and it all should(tm) work.

Due to lack of obio in amiga port, the probe is called directly from mbattach().
This is going to change with the introduction of obio for all non-autoconfig
expansions.
 1.2  22-Dec-2013  rkujawa Changes to ACA500 support:
- Add support for second (aux) CF slot.
- Rework wdc attachment to be more sane.
- Add support for clockport on ACA500.
- Fix style where appropriate.
 1.1  22-Dec-2013  rkujawa Add preliminary support for the Individual Computers ACA500 in the form of acahf
driver. If ACA500 is equipped with supported accelerator with MMU, it allows
running NetBSD on an Amiga 500.

Since ACA is not autoconf-aware, and the probe procedure does not exist yet, the
driver is activated with the ACA500_SUPPORT kernel option. The acahf driver
is commented out in the GENERIC kernel for now (at least until it stops being
very experimental and hackish).

When it comes to ACA-specific hardware, for now the boot CF slot works. Support for everything else is incoming...
 1.3.50.1  23-Mar-2021  thorpej Convert config_found_ia() call sites where the device only carries
a single interface attribute to bare config_found() calls.
 1.3.10.2  20-Aug-2014  tls Rebase to HEAD as of a few days ago.
 1.3.10.1  26-Dec-2013  tls file acafh.c was added on branch tls-maxphys on 2014-08-20 00:02:43 +0000
 1.3.6.2  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")
 1.3.6.1  26-Dec-2013  yamt file acafh.c was added on branch yamt-pagecache on 2014-05-22 11:39:28 +0000
 1.3.4.2  18-May-2014  rmind sync with head
 1.3.4.1  26-Dec-2013  rmind file acafh.c was added on branch rmind-smpnet on 2014-05-18 17:44:55 +0000
 1.4.8.1  03-Aug-2021  thorpej Adapt to CFARGS().
