add initial drm_fb framebuffer So far I can load fbcon, once I use my miniglx to add a framebuffer. fbcon doesn't show anything on screen but baby steps and all that.

Large changes for fbdev support. Change from DIRECTCOLOR to TRUECOLOR, and enable support for PSEUDOCOLOR. DIRECTCOLOR support needs more work. Add the ability to change the mode on the fbdev device. Support depth 8, 15, 16 and 24 (and 32). Add a /dev/fbX device per CRTC, but there's some code which doesn't allocate the fbX device unless the output is actually enabled. Read the code on this as it impacts the fbcon map flags. Pick CRTC's based on the available outputs. More work could be done here to match modes, so cloning could be achieved on outputs. This fits more inline with what the X code does.

Add locking. The main lock is dev->mode_config.config_lock. It should be held across any operations that modify mode lists, crtc config, output config, etc. It should be taken at high level entry points (currently just initial config and user IOCTL). Seems to work ok on my system, but needs more testing (with lockdep) and review from some fresh eyes.

Large changes for fbdev support. Change from DIRECTCOLOR to TRUECOLOR, and enable support for PSEUDOCOLOR. DIRECTCOLOR support needs more work. Add the ability to change the mode on the fbdev device. Support depth 8, 15, 16 and 24 (and 32). Add a /dev/fbX device per CRTC, but there's some code which doesn't allocate the fbX device unless the output is actually enabled. Read the code on this as it impacts the fbcon map flags. Pick CRTC's based on the available outputs. More work could be done here to match modes, so cloning could be achieved on outputs. This fits more inline with what the X code does.
