Jordan Crouse f378819a19 [PATCH] gxfb: Fixups for the AMD Geode GX framebuffer driver 
We cannot assume that the BIOS will be correctly setting up the hardware, so
set some bits in various display registers to enable video output.  Allow an
advanced user to specify a frambuffer size, rather then probing the BIOS.  All
of these fixes were prompted by the OLPC effort.

Jordan Crouse 4c1979c896 [PATCH] FB: Get the Geode GX frambuffer size from the BIOS 
Use the Geode GX BIOS virtual registers to get the actual size of the
framebuffer.

David Vrabel fc4effc7a9 [PATCH] fbdev: framebuffer driver for Geode GX 
A framebuffer driver for the display controller in AMD Geode GX processors
(Geode GX533, Geode GX500 etc.).  Tested at 640x480, 800x600, 1024x768 and
1280x1024 at 8, 16, and 24 bpp with both CRT and TFT.  No accelerated features
currently implemented and compression remains disabled.

This driver requires that the BIOS (or the SoftVG/Firmbase code in the BIOS)
has created an appropriate virtual PCI header.
