From 7458629de369a220ea24afdfbf5f1dc9fdc36a5e Mon Sep 17 00:00:00 2001 From: Nico Huber Date: Mon, 18 Feb 2019 01:21:11 +0100 Subject: drivers/intel/gma: Move gfxinit into sub package Move the actual graphics init provided by libgfxinit into a sub package `GMA.GFX_Init`. This way it can be compiled in individually.
