5c49fd3aa0 gma500: Add the core DRM files and headers
Not really a nice way to split this up further for submission. This
provides all the DRM interfacing logic, the headers and relevant glue.

5091b7eb3f gma500: Add the i2c bus support
Again this might be a candidate for sharing later.

f910b41105 gma500: Add the glue to the various BIOS and firmware interfaces
Some of this should one day become a library shared by i915 and gma500 I
suspct. Best however to deal with that later once it is all nice and
stably merged.

bbbb262d37 gma500: Add device framework
The devices have various internal differences so we have some abstractions
to hide the ugly differences and we then wrap them up in standard
interfaces. Add these bits

4d8d096e9a gma500: introduce the framebuffer support code
We support 2D acceleration on some devices but we try and do tricks with
the GTT as a starting point as this is far faster. The GTT logic could be
improved further but for most display sizes it already makes a pretty good
decision.

8c8f1c958a gma500: introduce the GTT and MMU handling logic
This fits alongside the GEM support to manage our resources on the card
itself. It's not actually clear we need to configure the MMU at all.
Further research is needed before removing it entirely. For now we suck it
in (slightly abused) from the old semi-free driver.

e32681d66d gma500: GEM and GEM glue
The driver uses GEM along with a couple of small bits of wrapping of its
own. The only real oddity here is the support for using the 'stolen' memory
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.

3abcf41fb1 gma500: Move the basic driver out of staging
This driver supports unaccelerated KMS display, and accelerated console
handling on the Intel Poulsbo, Oaktrail, Cedarview and Medfield hardware.

For the initial merge Medfield will be left out as it needs considerable
further work to reach a decent standard

Begin by adding the Makefiles and Kconfig. These are not yet plumbed into
the DRM layer so will have no effect on their own
