From 542e9488bd3f084c373e89e869aeca84aaa8c66c Mon Sep 17 00:00:00 2001 From: Nico Huber Date: Wed, 5 Oct 2016 17:47:32 +0200 Subject: drivers/intel/gma: Hook up libgfxinit 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.
