Make the reserved video memory on Geode GX1 based systems configurable.
This makes sense on systems with small memories when the VGA feature is not used (CONFIG_VIDEO_MB = 0 in this case). On Geode GX1 based systems the following amount of memory should be reserved when VGA support is enabled: - 1MiB for VGA and SVGA resolutions - 2MiB for XGA resolution - 4MiB for SXGA resolution Signed-off-by: Juergen Beisert <juergen127@kreuzholzen.de> Acked-by: Peter Stuge <peter@stuge.se> Acked-by: Uwe Hermann <uwe@hermann-uwe.de> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@2840 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
