2018-05-11drivers/intel/gma: honor vbt_size parameter to locate_vbt()Aaron Durbin
In 4a3956d7 (drivers/intel/gma, soc/intel/common: improve cooperation) the vbt_size parameter was not honored leading to the use of unitialized variables from the caller. Instead, keep track of if the vbt is already loaded by using the size returned from the load. If it's non-zero the vbt has been loaded.

2018-05-09drivers/intel/gma, soc/intel/common: improve cooperationPatrick Georgi
Instead of both featuring their own VBT loaders, use a single one. It's the compression-enabled one from soc/intel/common, but moved to drivers/intel/gma. The rationale (besides making all the Kconfig fluff easier) is that drivers/intel/gma is used in some capacity on all platforms that load a VBT, while soc/intel/common's VBT code is for use with FSP. BUG=b:79365806 TEST=GOOGLE_FALCO and GOOGLE_CHELL both build, exercising both affected code paths.

2018-04-133rdparty/libgfxinit: Update submodule pointerNico Huber
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.

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.

2017-10-23drv/intel/gma/opregion: fix opregion version for WindowsMatt DeVillier
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.

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.

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.

2016-12-19drivers/intel/gma: Use scaling to simplify fb configNico Huber
Utilize libgfxinit's support for scaling to simplify the framebuffer configuration. In case of multiple displays of different resolutions, 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.

Add an alternative gfxinit implementation for textmode. The legacy VGA plane and textmode is configured through coreboot provided functions. libgfxinit uses this plane as alternative to the usual high resolution plane.

2016-11-29drivers/intel/gma: Hook up libgfxinitNico Huber
Add `libgfxinit` as another option for native graphics initialization. For that, the function gma_gfxinit() (see drivers/intel/gma/i915.h) has to be called by the respective northbridge/soc code. 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.
