From 6f00494abed261cdbfdd003fe45f671eb3a56d78 Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann Date: Tue, 28 Oct 2014 10:09:11 +0100 Subject: [PATCH] vga: add default display to machine class This allows machine classes to specify which display device they want as default. If unspecified the current behavior (try cirrus, failing that try stdvga, failing that use no display) will be used. Signed-off-by: Gerd Hoffmann Reviewed-by: Michael S.
