* drivers/intel/gma: Add override for presence strapsMatt DeVillier2020-05-201-5/+22
| | | | | | | | | | | | | | A handful of boards do not properly implement the presence straps, leading libgfxinit to fail to detect an attached display. Add an override, defaulting to N, which can be set for affected boards. Add a section to the documentation detailing the option and its usage.

* 3rdparty/libgfxinit: Update submodule pointerNico Huber2020-03-091-8/+18
| | | | | | | | | | | | | | | | | | | | | | Changes allow to use the integrated panel logic (power sequen- cing and backlight control) for more connectors. The Kconfigs GFX_GMA_PANEL_1_PORT and GFX_GMA_PANEL_2_PORT can now be set to any port, e.g. config GFX_GMA_PANEL_1_PORT default "DP3" Now that the panel logic is not tied to the `Internal` port choice anymore, we can properly split it into `LVDS` and `eDP`. This also adds Comet Lake PCI IDs which should still work the same as Kaby and Coffee Lake.

* 3rdparty/lib{hwbase,gfxinit}: Update to latest masterNico Huber2017-10-281-11/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
