This is an initial import of the atom bios parser with modesetting support
for r500 hw using atombios. It also includes a simple memory manager
layer that translates a radeon GEM style interface onto TTM internally.
So far this memory manager has only been used for pinned object allocation
for the DDX to test modesetting.
- There is one fb, used for as many outputs as possible.
- Eventually smaller screens will be scaled to see the full console, but for the moment this'll do.
This splits a lot of the core modesetting code out into a file of
helper functions, that are only called from themselves and/or the driver.
The driver gets called into more often or can call these functions from itself
if it is a helper using driver.
I've broken framebuffer resize doing this but I didn't like the API for that
in any case.
The kernel has removed nopage so move the old nopage codepaths into a compat vm file and switch to using the fault paths.
nopfn is on its way out in the future also, so we should switch to using fault
for that path as well soon
It's not really a graphics memory allocator, just something to track ranges
of address space. It doesn't involve actual allocation, and was consuming
some desired namespace.
This should work on all radeon but there is still many things todo:
- add crtc2
- tmds
- lvds
- add bios data table so we don't need to hardcode dac/crtc infos
- separate clock control to make power saving easier & cleaner
- tiling (warning tiling shouldn't be enable in double scan or interlace)
- surface reg manager (this goes along with tiling)
- suspend/resume hook
- avivo & r500 family support
- atom bios support (for posting card mostly)
- finish superioctl skeleton
- what else ? :)

Fixup suspend/resume conflicts (basically use what's in DRM master for now).
Also fix up a few other conflicts that snuck in (i915_dma changes etc.).
All nv30 functions in nv30_graph.c that can be used on nv20 are renamed
as accordingly. nv20 specific parts from nv20_graph.c are moved into
nv30_graph.c.

Mostly removing typedefs that snuck into the modesetting code and
updating to the latest TTM APIs. As of today, the i915 driver builds,
but there are likely to be problems, so debugging and bugfixes will
come next.
