From 5cf88249236220ba4e1dc991e99b6bd823cf8de8 Mon Sep 17 00:00:00 2001 From: Kyösti Mälkki Date: Fri, 18 Oct 2013 11:02:56 +0300 Subject: via/vx900: Remove GFXUMA and use of related global variables MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Remove global variables uma_memory_base and uma_memory_size from builds with via/vx900 northbridge, as these variables can be kept within the chipset.
