 1.34  04-Nov-2023  tsutsui Add support for LCD-MONO framebuffer on NWS-32x0 laptop machines.

Tested on NWS-3260, which was sent from ryo@'s belongins and repaired
by me, and also tested on my NWS-3470D, including Xorg mono server.
(Note X.org server on NEWS machines requires keymap modifications)
Also add proper initialization on consinit() in NMB-253 case.

Worth to pull up to netbsd-10 and netbsd-9.
 1.33  28-Oct-2023  tsutsui Remove trailing spaces and tab.
 1.32  28-Oct-2023  tsutsui Use C99 designated struct initializers.
 1.31  28-Oct-2023  tsutsui Use proper C99 exact-width integer types.
 1.30  28-Oct-2023  tsutsui Make local functions and variables static.
 1.29  07-Aug-2021  thorpej branches: 1.29.6;
Merge thorpej-cfargs2.
 1.28  24-Apr-2021  thorpej branches: 1.28.8;
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?).
 1.27  21-Nov-2020  thorpej branches: 1.27.2;
malloc(9) -> kmem(9)
 1.26  31-Jan-2014  tsutsui branches: 1.26.34; 1.26.42;
Add WSDISPLAYIO_LINEBYTES ioctl (for Xorg wsfb driver).
 1.25  15-May-2010  tsutsui branches: 1.25.8; 1.25.18; 1.25.22;
Set RI_NO_AUTO in ri_flg if init functions are invoked from cnattach.
Tested on NWS-3470D. xafb.c for NWS-5000 is untested.

XXX: isn't it better to have failsafe default than sprinkle RI_NO_AUTO
XXX: to avoid fatal silent hangup?
 1.24  09-Apr-2008  tsutsui branches: 1.24.4; 1.24.24; 1.24.26;
Split device_t/softc, with misc cleanup.
 1.23  04-Mar-2007  christos branches: 1.23.40;
Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
 1.22  12-Apr-2006  jmmv branches: 1.22.14;
Add an extra cookie to the ioctl and mmap wsdisplay accessops that points
to the screen on which they are being called. The driver cannot guess
this by itself but it is needed to implement, at least, the getwschar and
putwschar functions in the correct place. There are no functional changes
yet.

Tested on i386 (vga, vga_raster, machfb, vesafb), macppc and sparc64.
Suggested and reviewed by macallan@.
 1.21  11-Dec-2005  christos branches: 1.21.4; 1.21.6; 1.21.8; 1.21.10; 1.21.12;
merge ktrace-lwp.
 1.20  03-Jun-2005  tsutsui branches: 1.20.2;
constify.
 1.19  06-Feb-2005  tsutsui Misc cleanup:
- ANSI function decls
- remove __P()
- u_intNN_t -> uintNN_t
- remove register decls
- bcopy -> memcpy, strcpy
- bzero -> memset
- bcmp -> memcmp
- use malloc(9) with M_ZERO
- some KNF
etc.
 1.18  07-Nov-2003  dsl branches: 1.18.8; 1.18.10;
default: to 1024x768 landscape if unknown geometry (avoids uninitialised vars)
 1.17  15-Jul-2003  lukem __KERNEL_RCSID()
 1.16  09-May-2003  tsutsui branches: 1.16.2;
- Define and use struct hb_attach_args rather than struct confargs
for hb devices.
- Move declarations for hb functions and macros to dev/hbvar.h.
- Define and use hb_badaddr() macro for hb devices.
- Declare news3400_badaddr() in machine/cpu.h rather than machine/autoconf.h.
- Remove unused stuff from machine/autoconf.h.
 1.15  19-Apr-2003  tsutsui TAB/space cleanup.
 1.14  02-Oct-2002  thorpej Use CFATTACH_DECL().
 1.13  27-Sep-2002  thorpej Declare all cfattach structures const.
 1.12  04-Jul-2002  junyoung alloc_attr -> allocattr

Approved by Matthias Drochner.
 1.11  31-May-2002  thorpej Statements must follow labels.
 1.10  17-Mar-2002  atatat branches: 1.10.4;
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.
 1.9  03-Dec-2000  matt branches: 1.9.4; 1.9.8;
Make this stuff compile with -wstrict-prototpes -wmissing-prototypes.
More use of prototypes inside includes should be done.
 1.8  15-Nov-2000  tsubai Fix an uninitialized variable reference.
 1.7  15-Nov-2000  tsubai Remove an unused variable.
 1.6  14-Nov-2000  tsubai Correct VRAM size.
 1.5  13-Nov-2000  tsubai Switch to wscons.
 1.4  26-Jun-2000  simonb Change the kernel mmap interface so that the offset to map is an
"off_t" and the return value is a "paddr_t" to allow mappings
at offsets past 2^31 bytes. Somewhat inspired by FreeBSD, which
only changed the offset to a "vm_offset_t".

Includes updates for the i386, pc532 and sh3 mmmmap from Jason Thorpe.
 1.3  15-Feb-1999  hubertf branches: 1.3.8; 1.3.18;
RCS ID police

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
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.

sys/arch/newsmips/dev/fb.c: revision 1.33

Make local functions and variables static.

Use proper C99 exact-width integer types.

Use C99 designated struct initializers.

Remove trailing spaces and tab.

Add support for LCD-MONO framebuffer on NWS-32x0 laptop machines.

Tested on NWS-3260, which was sent from ryo@'s belongins and repaired
by me, and also tested on my NWS-3470D, including Xorg mono server.
(Note X.org server on NEWS machines requires keymap modifications)

Also add proper initialization on consinit() in NMB-253 case.
 1.27.2.1  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.
 1.28.8.1  04-Aug-2021  thorpej Adapt to CFARGS().
