Dave Airlie b8c00ac5b5 drm/fb: add more correct 8/16/24/32 bpp fb support. The previous patches had some unwanted side effects, I've fixed the lack of 32bpp working, and fixed up 16bpp so it should also work. this also adds the interface to allow the driver to set a preferred console depth so for example low memory rn50 can set it to 8bpp. It also catches 24bpp on cards that can't do it and forces 32bpp. Tested on r100/r600/i945.

The Direct Rendering Manager (drm) is a device-independent kernel-level
device driver that provides support for the XFree86 Direct Rendering
Infrastructure (DRI).

The DRM supports the Direct Rendering Infrastructure (DRI) in four major
ways:

    1. The DRM provides synchronized access to the graphics hardware via
       the use of an optimized two-tiered lock.

    2. The DRM enforces the DRI security policy for access to the graphics
       hardware by only allowing authenticated X11 clients access to
       restricted regions of memory.

    3. The DRM provides a generic DMA engine, complete with multiple
       queues and the ability to detect the need for an OpenGL context
       switch.

    4. The DRM is extensible via the use of small device-specific modules
       that rely extensively on the API exported by the DRM module.


Documentation on the DRI is available from:
