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.

# Geode family framebuffer configuration

config FB_GEODE
bool "AMD Geode family framebuffer support (EXPERIMENTAL)"
depends on FB && PCI && EXPERIMENTAL && X86
---help---
Say 'Y' here to allow you to select framebuffer drivers for
the AMD Geode family of processors.
config FB_GEODE_GX
tristate "AMD Geode GX framebuffer support (EXPERIMENTAL)"
depends on FB && FB_GEODE && EXPERIMENTAL
select FB_CFB_FILLRECT
select FB_CFB_COPYAREA
select FB_CFB_IMAGEBLIT
---help---
Framebuffer driver for the display controller integrated into the
AMD Geode GX processors.
To compile this driver as a module, choose M here: the module will be
called gxfb.
If unsure, say N.
config FB_GEODE_GX_SET_FBSIZE
bool "Manually specify the Geode GX framebuffer size"
depends on FB_GEODE_GX
default n
---help---
If you want to manually specify the size of your GX framebuffer,
say Y here, otherwise say N to dynamically probe it.
Say N unless you know what you are doing.
config FB_GEODE_GX_FBSIZE
hex "Size of the GX framebuffer, in bytes"
depends on FB_GEODE_GX_SET_FBSIZE
default "0x1600000"
---help---
Specify the size of the GX framebuffer. Normally, you will
want this to be MB aligned. Common values are 0x80000 (8MB)
and 0x1600000 (16MB). Don't change this unless you know what
you are doing
config FB_GEODE_GX1
tristate "AMD Geode GX1 framebuffer support (EXPERIMENTAL)"
depends on FB && FB_GEODE && EXPERIMENTAL
select FB_CFB_FILLRECT
select FB_CFB_COPYAREA
select FB_CFB_IMAGEBLIT
---help---
Framebuffer driver for the display controller integrated into the
AMD Geode GX1 processor.
To compile this driver as a module, choose M here: the module will be
called gx1fb.
If unsure, say N.
