fffc6c4a80 Trapped into ifdef-hell. Configure libfaad's IRAM/DRAM usage like it is meant to be.

281666a066 The last submit had one define too much. Nevertheless fix the IRAM configuration for static allocation method.

2263cf35ab libfaad: AAC including HE-profile needs ~470 KB for playback (measured on ARM). Therefor it does not make sense to enable HE on devices with CODEC_SIZE < 512 KB. This will allow to load and play larger AAC-LC files on such devices.

a602f46d69 Rework of libfaad in several areas. Allow removal of malloc with a new define FAAD_STATIC_ALLOC (in common.h). For now malloc is not fully removed but used by a few arrays needed for AAC-HE SBR+PS only. Reason to keep malloc is to have this amount of memory available for AAC-LC files which might require large m4a tables. The changes make the allocation routines much smaller, better centralized and allow to move duplicated code from aac.c/raa.c to libfaad. The rework includes removal of (now and former) unused code as well.

ae019419ff Use the very large IRAM of S5L870x to speed up AAC-HE by ~1-5%.

560d89130f Using icode attribute for S5L870x is faster on some codecs. Speed up for mpc is ~3%, for aac ~1%.

cba9d259b0 Further libfaad cleanup. Make libfaad compilable for floating point. Floating point cannot be used as reference though, as errorous noise is the result.

52f17dfe9d Submit FS#11445. Speed up of faad (aac) decoder via several optimizations like refactoring some requantization routines, moving several arrays and code tables to IRAM, using an optimized swap32() function and inlining several huffman decoder functions. Decoding is sped up by ~10% (PP5002, PP5022, MCF5249) and ~22% (MCF5250).

50a6ca39ad Move c/h files implementing/defining standard library stuff into a new libc directory, also standard'ify some parts of the code base (almost entirely #include fixes). 
This is to a) to cleanup firmware/common and firmware/include a bit, but also b) for Rockbox as an application which should use the host system's c library and headers, separating makes it easy to exclude our files from the build.

af5bad46d8 Libfaad pow2/log2 improvements: 
Correct pow2_* to calculate correct output for input < 0.0 or between 0.0 and 1.0 instead of returning 0. This will change output, but the float version of this codec uses pow(2.0,x) in place of these functions, so this behavior was probably a bug
Replace 64-bit multiply in pow2_* with left or right shift by whole part of input, rounding if shifting right. An ARM-specific optimized version is provided as a C inline function, other targets use a C macro.
Increase constant size of table for pow2 to improve accuracy, also avoid early truncation in linear interpolation of result.
Move constant tables for pow2 and log2 to iram.

85aad9b397 Extend av_log2 in codeclib into a generic for scanning for set bits, which can provide either log2 or leading-zero-count output, and can force mapping 0 input to 0 output if needed (otherwise 0 input produces undefined result). Replace av_log2 in lib/codeclib.h, floor_log2 and wl_min_lzc in libfaad/common.c and common.h, and count_leading_zeros in libalac/alac.c with macros using bs_generic.

f5884fdeb6 Disable AAC-SBR, AAC-SSR, and AAC-PS on Sansa clip. Clean up warnings introduced by this. Enable compiling the AAC codec on the Clip. Due to lack of memory for seek tables, files over 10 minutes long or so will probably fail.

c6b3d38a15 New makefile solution: A single invocation of 'make' to build the entire tree. Fully controlled dependencies give faster and more correct recompiles. 
Many #include lines adjusted to conform to the new standards.

3fa5e5f592 Apply a bunch of simple AAC decoder optimizations. Biggest speedup is on ColdFire targets, but ARM targets benefits too. Allows realtime playback of some AAC files on Iriver targets (H1x0, H3x0). Remove support for some rarely used AAC profiles to reduce code size a bit.
