tridentfb: acceleration code improvements
This patch brings various acceleration improvements: - set copyarea/fillrect for non-accelerated framebuffer (fix) - remove 15 bpp depth handling to simplify code as it hardly works (15 bpp handling was obviously missing in some switches) - add fb_sync call and move waiting before accelerated function to make acceleration more asynchronous to cpu (few % of speed improvement) - add cpu_relax() call in waiting loops - make longer register names and name more registers - move registers' definition to header - general code improvements (shortening, simplifying) Signed-off-by: Krzysztof Helt <krzysztof.h1@wp.pl> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
