05099149f1 Enable nocache sections using the linker. PP5022/4 must use SW_CORELOCK now with shared variables in DRAM (it seems swp(b) is at least partially broken on all PP or I'm doing something very wrong here :\). For core-shared data use SHAREDBSS/DATA_ATTR. NOCACHEBSS/DATA_ATTR is available whether or not single core is forced for static peripheral-DMA buffer allocation without use of the UNCACHED_ADDR macro in code and is likely useful on a non-PP target with a data cache (although not actually enabled in config.h and the .lds's in this commit).

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.

a222f27c4a mpegplayer: Make playback engine fully seekable and frame-accurate and split into logical parts. Be sure to have all current features work. Actual UI for seeking will be added soon. Recommended GOP size is about 15-30 frames depending on target or seeking can be slow with really long GOPs (nature of MPEG video). More refined encoding recommendations for a particular player should be posted soon.

fd3fe45bc1 FS#7487 - mpegplayer - video start time seek with resume 
by John S. Gwynne & Brian J. Morey
This should stop the patch from breaking again and give them opportunity to improve it further.

8310848421 Some small mpegplayer improvements/bug-fixes, and improved A/V sync. Audio is used as the master clock and video is synced to the number of samples played. This doesn't take account of any PTS difference at the start of the stream. Also enable Limit FPS and Skip Frames by default - these options need to be enabled for A/V sync to work. Adds pcm_get_bytes_waiting() to the plugin API

4b801b2d3a Initial implementation of audio support (44.1KHz only, mp2 or mp3, mono/stereo, any bitrate) and .mpg file (MPEG program stream) parsing for mpegplayer - .m2v files are no longer supported. .mpg parser based on patch #6366 from Mathieu Favreaux. Currently limited to only playing files smaller than the available buffer RAM (it will play longer files, but never refills the buffer when it runs empty). There is also no a/v sync implemented, and still no seeking support. Coldfire (iriver H3x0 and iaudio X5) users can use the optimisations provided in patch #5995 to increase the framerate, and PortalPlayer (ipods and iriver H10) users will want to use kernel_on_cop_6.diff from FS#5755 which enables mpegplayer to run the video thread on the second CPU core - video on the second core with audio on the first core runs at the same speed as the old mpegplayer did with no audio.

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.
