Log:
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
