0beb62760d 3rdparty/libgfxinit: Update submodule pointer
Update libgfxinit to current master. Changes include:

* a fix to decode the size stolen memory correctly on pre-SandyBridge
  hardware,
* a PCI id based generation check, obsoleting the old check based
  on PCH audio ids,
* some minor improvements around rarely used DDI ports (D and E), and
* added support for tiled and rotated framebuffers on Skylake+ hardware
  (less interesting for coreboot, I guess?).

TEST=Booted kontron/ktqm77 (Ivy Bridge) and pending kontron/bsl6
     (Skylake) both with text and linear framebuffers and observed
     FILO's prompt showing up.

71cbd71eb5 drivers/intel/gma: Depend less on default fb values
Instead of hard-coding a lot of default values of the framebuffer config,
we use the values provided by Display_Probing.Scan_Ports() and only
overwrite what is necessary. This way we are more independent from
changes inside libgfxinit.

06c8c0d1fe drivers/intel/gma: Amend stride calculation of linear fb
Aligning the stride up to a multiple of 64 pixels was flawed: We want
to actually align up to one cacheline (64 bytes) as that's the mini-
mum what the hardware supports.

681ef51d73 drivers/intel/gma: fix opregion SCI register for Atom platforms
Most Intel platforms use separate registers for software-based
SMI (0xe0) and SCI (0xe8), but Atom-based platforms use a single
combined register (0xe0) for both. Adjust opregion implementation
to use the correct register for Atom-based platforms.

Test: Boot Windows on Atom-based ChromeOS device with Tianocore
payload and non-VBIOS graphics init; observe Intel display
driver loaded correctly and internal display not blank.
(requires additional change for Atom platforms to select
CONFIG_INTEL_GMA_SWSMISCI)

504d1eff4b 3rdparty/lib{hwbase,gfxinit}: Update to latest master
Simplifies our C interface function gma_gfxinit(), due to the following
changes:

* *libgfxinit* knows about the underlying PCI device now and can
  probe MMIO addresses by itself.
* The framebuffer mapping is now completely handled inside the
  library where we validate that we neither overflow
  - the stolen memory,
  - the GTT address space, the GTT itself nor
  - the aperture window (i.e. resource2 of the PCI device)
    that we use to access the framebuffer.

Other changes:

* Fixes and a quirk for DP training.
* Fix for DP-VGA adapters that report an analog display in EDID.
* Fixes for Skylake support with coreboot.
* DDI Buffer drive-strength configuration for Haswell, Broadwell and
  Skylake.
* `gfx_test` can now be run from X windows (with glitches).
* Compatibility with GCC 7 and SPARK GPL 2017.

TEST=Booted lenovo/t420 and verified that everything works as usual.

fd0a891ee9 drv/intel/gma/opregion: fix opregion version for Windows
Although Intel's current spec[1] shows the OpRegion structure version 
as being the top 16 bits of the field, Intel's Windows drivers
require the OpRegion structure version to be in the top 8 bits of
the field when not using a VGA BIOS (eg, NGI or GOP driver).

As the Linux i915 driver only checks that the version is >= 2,
there is no change in functionality there.

This change effectively matches Intel's implementation in TianoCore,
where the version is set to 0x0200 << 16.

[1] https://01.org/sites/default/files/documentation/skl_opregion_rev0p5.pdf

TEST: Boot Windows [8.1,10] in UEFI mode w/GOP graphics init and
Legacy mode with libgfxinit, observe Intel GPU driver functional.

* Try to locate vbt.bin in CBFS.
* Try to locate VBIOS in CBFS.
* Keep existing code to probe at 0xc0000.

Tested on Lenovo T430 (sandybridge) using vbt.bin, tested using buggy
VBIOS with wrong vbt_offset, tested with fake vbt written by NGI at
0xc0000.

Tested with https://review.coreboot.org/#/c/21766/ on i945 (using fake
vbt at 0xc0000), x4x (using vbt.bin) and gm45 (using vendor VBIOS).
In all cases linux was successfully provided with VBT from ACPI

bdb5c8feae coreboot_tables: specify clear interface for lb_framebuffer()
For some reason the "interface" for adding framebuffer information
is sitting in src/include/vbe.h while also guarding the call to
fill_lb_framebuffer() with vbe_mode_info_valid() along with some
macro if CONFIG_* for good measure.

Move the fill_lb_framebuffer() declaration to coreboot_tables.h and
provide a comment about how it should be used. Also, now that
there's no need for the notion of a global vbe_mode_info_valid()
remove it from the conditional call path of fill_lb_framebuffer().

989aae9f61 3rdparty/libgfxinit: Update submodule pointer
Some renamings force us to update our code:

  * Scan_Ports() moved into a new package Display_Probing.

  * Ports Digital[123] are called HDMI[123] now (finally!).

  * `Configs_Type` became `Pipe_Configs`, `Config_Index` `Pipe_Index`.

Other noteworthy changes in libgfxinit:

  * libgfxinit now knows about ports that share pins (e.g. HDMI1 and
    DP1) and refuses to enable any of them if both are connected
    (which is physically possible on certain ThinkPad docks).

  * Major refactoring of the high-level GMA code.

8e079000dc nb/i945/gma.c: Refactor panel setup
This reuses some of gm45 code to set up the panel.

Panel start and stop delays and pwm frequency can now be set in
devicetree.

Linux does not make the difference between 945gm and gm45
for panel delays, so it is safe to assume the semantics of those
registers are the same.

The core display clock is computed according to "Mobile Intel® 945
Express Chipset Family" Datasheet.

This selects Legacy backlight mode since most targets have some smm
code that rely on this.

This sets the same backlight frequency as vendor bios on Thinkpad X60
and T60.

A default of 180Hz is selected for the PWM frequency if it is not
defined in the devicetree, this might be annoying for displays that
are LED backlit, but is a safe value for CCFL backlit displays.

561bebfbaa drivers/intel/gma/vbt: Add Kconfig symbol for SSC ref
The selection of the SSC reference frequency for LVDS was based on a
completely unrelated clock.

The `ssc_freq` flag should be set when the SSC reference runs at a
different frequency than the general display reference clock (DREF).
For most platforms, there is no choice, i.e. for i945 and gm45 the SSC
reference always differs from the display reference clock (i945: 66Mhz
SSC vs. 48MHz DREF; gm45: 100MHz SSC vs. 96Mhz DREF), for Nehalem and
newer, it's the same frequency for SSC/non-SSC (120MHz).  The only,
currently supported platform with a choice seems to be Pineview, where
the alternative is 100MHz vs. the default 96MHz.

we had configured one framebuffer big enough for their union, each
display only showing its respective upper left window. Instead, we use
the smallest resolution now and show the whole image on all displays.

For that, the function gma_gfxinit() (see drivers/intel/gma/i915.h) has

A mainboard port needs to select `CONFIG_MAINBOARD_HAS_LIBGFXINIT` and
implement the Ada package `GMA.Mainboard` with a single function `ports`
that returns a list of ports to be probed for displays.

v2: Update 3rdparty/libgfxinit to its latest master commit to make
    things buildable within coreboot.

v3: Another update to 3rdparty/libgfxinit. Including support to select
    the I2C port for VGA.

deeec18520 gma ACPI: Do not overwrite backlight configuration
Changes to CR1 and CR2 were effectively overwriting the backlight
configuration from the devicetree with static values.

Instead read the maximum brightness value from BCLM (backlight
modulation frequency) and calculate the target level (Arg0 is the
target level as percentage).

Turned out that _BQC has to return a value from the list returned by
_BCL. So XBQC got a little heavier to search for the correct value.
