e2e022ec51 gma500/oaktrail: panel display quality fix
The GCT setup was used on Moorestown. The Oaktrail version uses a normal PC
interface. That means we must also honour the dither info from the BIOS
data.

0cecdd818c gma500: Final enables for Oaktrail
This switches the ifdef to match the Kconfig so that Oaktrail probing occurs
and adds some additional minor bulletproofing.

fea578b6a1 gma500: SDVO DDC bus guessing isn't working so hardcode it instead
We currently don't have support for parsing SDVO mappings from BIOS so we're
guessing the bus switch parameter. This isn't working so hardcode it to a
configuration known to work on most poulsbo hardware.

aa0c45fdca gma500: Fix oaktrail probing part 1
The Oaktrail platform does not use the GCT/VBT format that is used by the
Moorestowm (non PC legacy) equivalent device. It uses the BIOS tables which
means an opregion and the like.

The current code uses the wrong table which breaks things like the Fujitsu
q550 tablets. Fix the table usage as a first step.

The problem was found and diagnosed by Chia-I Wu

a6ba582d26 gma500: gtt based hardware scrolling console
Add support for GTT based scrolling. Instead of pushing bits around we simply
use the GTT to change the mappings. This provides us with a very fast way to
scroll the display providing we have enough memory to allocate on 4K line
boundaries. In practice this seems to be the case except for very big displays
such as HDMI, and the usual configurations are netbooks/tablets.

89c78134cc gma500: Add Poulsbo support
This provides the specific code for Poulsbo, some of which is also used for
the later chipsets. We support the GTT, the 2D engine (for console), and
the display setup/management. We do not support 3D or the video overlays.

In theory enough public info is available to do the video overlay work
but that represents a large task.

Framebuffer X will run nicely with this but do *NOT* use the VESA X
server at the same time as KMS. With a Dell mini 10 things like Xfce4 are
nice and usable even when compositing as the CPU has a good path to the
memory.

The driver uses GEM along with a couple of small bits of wrapping of its

rather than wasting several MB.

We use a simple resource manager as we don't need to manage our space
intensively at all as we only do 2D work. We also have a GTT which is
entirely GPU facing so in the Cedarview case are not even allocating from
host address space.
