 1.20  07-Aug-2021  thorpej Merge thorpej-cfargs2.
 1.19  24-Apr-2021  thorpej branches: 1.19.8;
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?).
 1.18  07-Mar-2021  rin branches: 1.18.2;
Add initial support for Xorg server for wsfb(4):

- Fix WSDISPLAYIO_GTYPE ioctl.

- Support WSDISPLAYIO_LINEBYTES, _{GET,PUT}CMAP, and _SMODE ioctl.

As well as tiny improvements related to it:

- Use actual size of framebuffer for bus_space_mmap(9), as well as upper
bound for mmap(2).

- Use base address obtained from autoconf(9) layer for mmap(2), instead of
hard-coded one.

- Use rasops_cmap as default color map, instead of our own ANSI color map.

- Show monitor resolution and color depth instead of size as tty.

I've confirmed that mlterm-fb from pkgsrc/x11/mlterm also works fine.
 1.17  07-Mar-2021  rin Misc cleanup for clarity. No functional changes.

- Group function declarations, and reorder function bodies accordingly.
- Misc KNF.
 1.16  05-Mar-2021  rin Fix color map.

Almost all colors except *green* were wrong for the apparent reason ;).
 1.15  05-Mar-2021  rin Configure fb(4) appropriately also when it is not console.

Now, wsdisplay(4) can be used with serial console.
 1.14  21-Nov-2020  thorpej malloc(9) -> kmem(9)
 1.13  01-Jul-2011  dyoung branches: 1.13.66;
#include <sys/bus.h> instead of <machine/bus.h>.
 1.12  18-Jun-2011  matt split device/softc (CFATTACH_DECL_NEW)
struct device * -> device_t
struct cfdata * -> cfdata_t
Use <sys/foo.h> instead of <machine/foo.h> if <sys/foo.h> exists
Explicitly include <powerpc/ibm4xx/cpu.h> when needed.
 1.11  15-May-2010  tsutsui branches: 1.11.6;
Clear RI_NO_AUTO in actual attach functions during autoconf(9)
for console devices that set the flag during consinit().
 1.10  15-May-2010  tsutsui Set RI_NO_AUTO in ri_flg if fb_init() is invoked from cnattach.
Tested on Explora451.
 1.9  28-Apr-2008  martin branches: 1.9.20; 1.9.22;
Remove clause 3 and 4 from TNF licenses
 1.8  04-Mar-2007  christos branches: 1.8.40; 1.8.42; 1.8.44;
Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
 1.7  13-Apr-2006  hannken branches: 1.7.14;
Make it compile again by adding a second cookie to ioctl and mmap
wsdisplay accessops.
 1.6  11-Dec-2005  christos branches: 1.6.4; 1.6.6; 1.6.8; 1.6.10; 1.6.12;
merge ktrace-lwp.
 1.5  13-Sep-2004  drochner branches: 1.5.12;
use config_found() instead of config_found_sm() if no submatch
function is used
 1.4  05-Jan-2004  hannken Implement fb_mmap(). From David P. Reese Jr. with PR #23985.
 1.3  15-Jul-2003  lukem __KERNEL_RCSID()
 1.2  17-Mar-2003  hannken branches: 1.2.2;
Add hardware accelerated copy/erase ops.
 1.1  11-Mar-2003  hannken Add a port to the NCD Explora451 ThinClient.

- Supported devices: le, com, lpt, pckbd, frame buffer.
- Support missing: phy, audio, pcmcia.
- Boots from network or md.
