2. Open file ->

vim src/drivers/intel/gma/Kconfig +90

Add like so that it looks like: 

|| SOC_INTEL_WHISKEYLAKE || SOC_INTEL_COMETLAKE

So, I have made the change to src/drivers/intel/gma/Kconfig and when I run the build it now gives the error:

warning: (BOARD_SPECIFIC_OPTIONS) selects GFX_GMA which has unmet direct dependencies ((NORTHBRIDGE_INTEL_GM45 || NORTHBRIDGE_INTEL_X4X || NORTHBRIDGE_INTEL_IRONLAKE || NORTHBRIDGE_INTEL_SANDYBRIDGE || NORTHBRIDGE_INTEL_HASWELL || SOC_INTEL_BROADWELL || SOC_INTEL_SKYLAKE || SOC_INTEL_APOLLOLAKE || SOC_INTEL_KABYLAKE || SOC_INTEL_COFFEELAKE || SOC_INTEL_WHISKEYLAKE || SOC_INTEL_COMETLAKE) && (MAINBOARD_USE_LIBGFXINIT || INTEL_GMA_LIBGFXINIT_EDID))

As there is a && in the middle of the expression I have tried adding the MAINBOARD_USE_LIBGFXINIT option but that doesn’t fix the build either!
