 1.28  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.
 1.27  22-Jan-2022  thorpej Change the devhandle_from_*() functions to also take a "super handle",
from which the newly created handle will inherit it's implementation.
The root implementation for a new handle type is used if an invalid
"super handle" is passed.
 1.26  07-Aug-2021  thorpej Merge thorpej-cfargs2.
 1.25  24-Apr-2021  thorpej branches: 1.25.8;
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?).
 1.24  05-Mar-2021  rin branches: 1.24.2;
Convert to intr_establish_xname().
 1.23  26-Jan-2021  thorpej There is not much point in of_compatible() returning -1 for "no match"
and >= 0 for "match". Just make it return 0 for "no match" and >0 for
"match" so it can be treated like a boolean expression.

As such of_match_compatible() (a wrapper around of_compatible()) is now
obsolete, and will be removed once all call sites are converted to an
appropriate replacement.
 1.22  26-Jul-2011  macallan branches: 1.22.66;
finish device_t-ification
 1.21  30-Jun-2011  matt Modify mapiodev to take a third argument indicating whether the space
should be prefetchable (true) or not (false).
 1.20  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
 1.19  20-Dec-2010  matt branches: 1.19.6;
Move counting of faults, traps, intrs, soft[intr]s, syscalls, and nswtch
from uvmexp to per-cpu cpu_data and move them to 64bits. Remove unneeded
includes of <uvm/uvm_extern.h> and/or <uvm/uvm.h>.
 1.18  14-Mar-2009  dsl branches: 1.18.4;
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.
 1.17  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.)
 1.16  14-Mar-2009  dsl Remove all the __P() from sys (excluding sys/dist)
Diff checked with grep and MK1 eyeball.
i386 and amd64 GENERIC and sys still build.
 1.15  28-Aug-2008  jmcneill branches: 1.15.2; 1.15.8;
Add support for keylargo-style mediabays, as found in eg. PowerBook3,1
 1.14  17-Oct-2007  garbled branches: 1.14.16; 1.14.20; 1.14.22; 1.14.26;
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.

 1.2.2.1  20-Nov-2000  bouyer Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as

-current, as well as machine-dependant code.

Follow the merge of pmap.c on i386 and amd64 and move

and config_found_ia() call sites will be in subsequent commits.
