[PATCH] Update cyblafb driver
This is a major update to the cyblafb framebuffer driver. Most
of the stuff has been tested in the mm tree.
Main advantages:
============
- vxres > xres support
- ywrap and xpan support
- much faster for almost all modes (e.g. 1280x1024-16bpp
draws more than 41 full screens of text instead of about 25
full screens of text per second on authors Epia 5000)
- module init/exit code fixed
- bugs triggered by console rotation fixed
- lots of minor improvements
- startup modes suitable for high performance scrolling
in all directions
This diff also contains a lot of white space fixes.
No side effects are possible, only one single graphics core is affected.
