2023-01-26drivers/intel/gma: Use libgfxinit Update_Output to turn off graphicsJeremy Compostella
We were using the libgfxinit `Initialize' function with the `Clean_State' parameter because the more appropriate `Update_Output' function was not performing all the necessary clean up operations for the PEIM driver to be successful when libgfxinit was used in romstage. Thanks to a lot of experiments and some log analysis efforts, we were able to identify the missing operation and fix the `Update_Output' function (cf. https://review.coreboot.org/c/libgfxinit/+/72123). The `initialized' global variable is now unnecessary as we track the initialization in the Ada code instead. Since the `Update_Output' function does not return any value, this patch modifies the `gma_gfxstop' prototype accordingly. This does not have any impact as the return value was not used anyway.

2023-01-12soc/intel/common/block: Add Intel VGA early graphics supportJeremy Compostella
This patch introduces an early graphics driver which can be used in romstage in cache-as-ram mode. The implementation relies on `libgfxinit' and provide VGA text mode support. SoCs wanting to take advantage of this driver must implement the `early_graphics_soc_panel_init' function to set the panel power sequence timing parameters.

2020-03-093rdparty/libgfxinit: Update submodule pointerNico Huber
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.

2017-10-283rdparty/lib{hwbase,gfxinit}: Update to latest masterNico Huber
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.
