Merge thorpej-cfargs2.

Adapt to CFARGS().

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?).

Make sure to explcitly specify the "wsemuldisplaydev" interface attribute
when attaching the wscons display instance, because these devices can
also attach children using the "drm" interface attribute.

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.

BUS_SPACE_MAP_PREFETCHABLE yields a write combining region on x86 and that's
not what I intended.. BUS_SPACE_MAP_CACHEABLE is enough.

Mostly merge changes from HEAD upto 20200411

Merge changes from current as of 20200406

Mark res __diagused; #ifdef DIAGNOSTIC panic ---> KASSERT.

Map the video RAM cacheable/prefetchable, it's very slow and this helps a bit.

in many device attach paths, allocate memory with M_WAITOK instead of M_NOWAIT
and remove code to handle failures that can no longer happen.

Update haad-dm branch to haad-dm-base2.

Calculate maxdispoffset rather than hard-coding it. Fixes scrolling in
80x25 mode.

XXX This doesn't handle odd modes like 80x30 on 640x480, but the driver
didn't allow that selection previously so at least it's an improvement
over the previous behaviour.

vga_cnattach: calling wsdisplay_screentype_pick with a NULL type will
select the first entry in the list, which overrides the selected screen
type. Only call it a second time if the original selection is invalid.

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@.

Implement the replaceattr emulop.

Fix the eraserows operation, which was using an incorrect value to paint
the background.  The problem was exposed when setting a non-black color
as the background, as the shift did not produce the expected fill value
(for black it worked because 0 is black).

add missing __KERNEL_RCSID()

As beginning of merging uwscons to -current:
- Add a (temporary) printf to vga_raster_load_font() for tracking font
  loading process. If you encountered "vga_raster_load_font: called"
  kernel message, please let me know.
- While here, some KNF.

Changes to allow machines which don't use text mode at the boot time
to use generic VGA driver(s):
- Allow VGA drivers to use wsfont instead of builtin font.
- Add vga_reset() function, which will be called from MD consinit(),
  to put VGA into text mode. This function is enabled by options VGA_RESET.

Set a value for MISCOUT register correctly in vga_setup_regs().

const'ify.

- Replace some magic numbers with proper macro.
- Use vga_6845_{read,write}() defined in pcdisplayvar.h and
  remove vga_crtc_{read,write}() macros in vgareg.h.

KNF and space/TAB cleanup.

Sync with HEAD.

Fix compile error.

Missing '.'

Now VGA_CONSOLE_SCREENTYPE can be specified with VGA_RASTERCONSOLE.
Currently only 80x25 and 80x30 modes are supported.

Simplify vga_raster_setscreentype() and clean up code.

Catch up to -current.

file vga_raster.c was added on branch nathanw_sa on 2002-10-18 02:42:01 +0000

Add VGA raster graphics console driver. It is written as an extension
to char-cell based vga(4) driver, and fully compatible with existing
apps like XFree86. Currently it supports 80x25, 80x30, 80x40 and 80x50
text modes using emulation. You can enable it by specifying `options
VGA_RASTERCONSOLE' in your kernel config file.

Note that displaying multilingual text doesn't work yet. Necessary
code is already there, but userland stuff and some functionality isn't
ready for prime time yet. I'm working on them.
