ff9f3f8c04 Revert r14786 which resulted in a substantial reduction in accuracy to save a 7.6KB of RAM. Accuracy should be greatly improved now, and if we want to make that trade off again, I think of better ways to do it.

dab9fa1ef7 Fix for WMAv1 decoding suggested by Rafael Carre. I don't think anyone out there will ever use V1, but its worth having correct code for its own sake.

c0951d95b3 Resort operands in mul/smull/mla/smlal to use D[] as second multiplication operand. Additionally do not pre-scale D[] for the 64 Bit precision synthesizer. Through this the 64 Bit multiplication is speed up by 1.5MHz without loss of precision.

cc11e9466a Further changes in mpc buffered seek. Remove magical number and replace it with a better commented #define. Use shift and bit mask instead of division and modulo operations when using the seek buffer. Saves some binary size for the codec.

bc97952134 libmad: PP5002 does in fact profit more from -O2 than PP502x, so use it for all targets. The previous check was half-baked (excluded iPod 3rd Gen only, but 1st/2nd Gen are also PP5002).

6a74a5dd3b Commit FS#9015. Rework of musepack buffered seek. Now a static seek buffer of 8192 entries is used. The seeking precision is adapted to the length of the file (e.g. 26ms for files <=3.5min and 0.4s for files ~60min).

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).
