 1.38  26-Oct-2022  andvar nix double n, i or g in "ing", in comments and documentation.
 1.37  07-Aug-2021  thorpej Merge thorpej-cfargs2.
 1.36  24-Apr-2021  thorpej branches: 1.36.8;
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?).

 1.32  07-Aug-2017  uwe branches: 1.32.2; 1.32.4;
XXX: On hpcsh only - bring back old incorrect hpckbd_keymap_setup()
fixed in 1.31. The old one with UNCONST does work on hpcsh b/c the
kernel is directly mapped. The new one does not work on hpcsh b/c it
calls consinit() very early when malloc() is not yet available.

The real fix for this is to fix the constness of wscons keymap
structures that is self-contradictory.
 1.31  12-Jun-2017  manu Restore wscons keymaps feature on hpcarm

hpc ports need to alter keydesc data at runtime in order to load
alternate keymaps. But since keydesc is const initialized data, it
is mapped read only and the operation should fail.

It seems older compiler failed to enforce the read-only mapping and
this is why it used to work, but on recent NetBSD releases, the
feature is broken.

We fix it by duplicating the keydesc data once into a malloc'ed area
that can be modified.
 1.30  27-Oct-2012  chs branches: 1.30.12; 1.30.14; 1.30.30;

Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
 1.21  29-Jan-2007  hubertf branches: 1.21.2;
Remove more duplicate headers.
Patch by Slava Semushin <slava.semushin@gmail.com>

Again, this was tested by comparing obj files from a pristine and a patched
source tree against an i386/ALL kernel, and also for src/sbin/fsck_ffs,
src/sbin/fsdb and src/usr.sbin/makefs. Only changes in assert() line numbers
were detected in 'objdump -d' output.
 1.20  16-Nov-2006  christos __unused removal on arguments; approved by core.
 1.19  12-Oct-2006  uwe -Wextra fixes
 1.18  24-Sep-2006  peter Run the "power button event" hooks when the special button OFF is pressed.
Change the keycodes in the keymaps that are currently using the OFF button
to -1 so that they will still operate the same way (i.e. do nothing).

No objection on port-hpcsh & port-hpcmips.
 1.17  29-Mar-2006  thorpej branches: 1.17.8; 1.17.10;
Use device_private().
 1.16  13-Feb-2006  uwe branches: 1.16.2; 1.16.4; 1.16.6;
Move assignment out of conditional expression.
 1.15  12-Feb-2006  peter Fix a typo, use uintN_t, use assigned variables, add newline to a printf.
 1.14  11-Dec-2005  christos branches: 1.14.2; 1.14.4; 1.14.6;
merge ktrace-lwp.
 1.13  08-Jun-2005  he branches: 1.13.2;
Add an __UNCONST() to appease -Wcast-qual.

XXX The way this is done is really wrong, as this function ends up
modifying read-only data marked with 'const'.
The reason we can get away with this is that apparently all the
ports using this code maps text and read-only data read-write.

Reviewed by christos, who suggested "a big XXX comment".
 1.12  27-Feb-2005  perry nuke trailing whitespace
 1.11  13-Mar-2004  bjh21 branches: 1.11.8; 1.11.10;
Abstract the interface between pckbc(4), and the pckbd(4) and pms(4)
drivers that attach to it. This allows for other host interface chips
that use the same keyboards and mice, such as the ones in the ARM
IOMD20, ARM7500, and SA-1111. The PC-compatible driver is still
called pckbc(4), and the new abstraction layer is "pckbport", so the
child devices have moved from sys/dev/pckbc to sys/dev/pckbport, which
also contains some code shared between all host controllers. To avoid
incompatibility, pckbdreg.h is still installed in
/usr/include/dev/pckbc.

In theory, this shouldn't cause any behavioural changes in the drivers
concerned. Thy just use rather more function pointers than before. Tested
on i386 and (with a new host driver) acorn32. Compiled on several other
affected architectures.
 1.10  02-Oct-2002  thorpej branches: 1.10.6;
Add trailing ; to CFATTACH_DECL.
 1.9  30-Sep-2002  thorpej Use CFATTACH_DECL().
 1.8  27-Sep-2002  thorpej Declare all cfattach structures const.
 1.7  17-Mar-2002  atatat Convert ioctl code to use EPASSTHROUGH instead of -1 or ENOTTY for
indicating an unhandled "command". ERESTART is -1, which can lead to
confusion. ERESTART has been moved to -3 and EPASSTHROUGH has been
placed at -4. No ioctl code should now return -1 anywhere. The
ioctl() system call is now properly restartable.
