2007-07-16	drm: remove drmP.h internal typedefs	Dave Airlie

2005-11-28	Assert an MIT copyright on sis_drm.h, since one was lacking and I created	Eric Anholt
	that particular file. Its contents have changed a good bit since the original sis code, and the original sis code didn't care much about attribution since it routinely disclaims Precision Insight/VA Linux from responsibility. Also, adjust formatting around license headers (have a comment open immediately before the "Copyright" line, not as a runon of any previous comments) for automatic processing into FreeBSD, where /*- is used to signal the beginning of license headers for automatic compilation of license lists.
2004-09-30	Lindent of core build. Drivers checked for no binary diffs. A few files	Jon Smirl
	weren't Lindent's because their comments didn't convert very well. A bunch of other minor clean up with no code implact included.
2004-09-27	First check in for DRM that splits core from personality modules	Jon Smirl

2004-08-24	Merged drmfntbl-0-0-2	Dave Airlie

2004-04-12	Add mach64 to the trunk	Dave Airlie
