0c7f2372d5 libmpeg2: Decode only Y on grayscale targets. The chroma skip code is probably less than optimal since it's basically the decoding code with minimum reading of the bitstream but it does the trick for now and gets some more FPS.

2b5f979d75 Reformat and code police (tabs, trailing whitespace, annoying overuse of parentheses, etc.) in libmpeg2 so I can stomach working on it. Don't call IDCT functions through pointers - I don't feel like extracting that change just for relevance sake.

fc43b9df82 Mpegplayer: Assembler optimised IDCT for coldfire, based on FS #5995 by Karim Boucher. Put the IDCT block buffer in IRAM for better performance. The whole libmpeg2 decoder struct doesn't fit without throwing some libmad buffers out of IRAM, but then doesn't change performance significantly. Mpegplayer is quite usable now on X5; H300 is sort-of usable for widescreen.

f4b5a723b0 mpeg2dec in mpegplayer: Do a little code slashing and organizing. Much more to come I think.

c9d66562af Initial commit of work-in-progress MPEG video player plugin based on libmpeg2. Works on all targets with colour LCDs, but most optimised for the ipod Color/Photo and Nano. It currently only plays raw MPEG-1 or MPEG-2 video streams (no audio). Also adds a new lcd_yuv_blit() function to the plugin API - currently only implemented for the ipod Color/Photo and Nano.
