From: Akash Goel <akash.goel@xxxxxxxxx>
These patches are mainly for increasing the utilization
of stolen memory area on VLV.
Although the changes were already there to allocate few
internal resources from stolen area, but due to a resource
conflict the stolen area was not getting used at all.
The third patch is also a bug fix but specific only to VLV.
The rest of the patches actually increase the utilization
stolen area on VLV by allocating User created frame buffers
(only X tiled).
These changes proved especially useful for Android BYT products,
which had smaller RAM(1GB), where it enabled playback of most
of the available 3D games/Apps.
