12375d1d3a Merge functionality of wakeups and semaphores-- fewer APIs and object types. semaphore_wait takes a timeout now so codecs and plugins have to be made incompatible. Don't make semaphores for targets not using them.

9f0bad0efe Byteswap routines don't really need 'asm volatile', just 'asm' since it should be safe to move them for optimizing. Clean up the line endings for ARM.

18770dac2e Use __builtin_constant_p() to select the best byteswapping method: constant or target optimized. Same macro can then be used for constant values and inits as well as non-constant.

3b402e254a Change "r" back to "i" (i is for immediate, so no syntax error) and reclaim a bit binsize. Live with that those function don't build with -O0 since they rely on inlining.

a1bc3401f1 Fix a few possible problems discovered in -O0 / eabi experiments. 
- two essential parts of Sansa AMS drivers are optimzed away in newer gcc, so mark them volatile.
- use "r" instead of "i" (which is apparently invalid syntax) for the input list in some inline assembly

2acc0ac542 Updated our source code header to explicitly mention that we are GPL v2 or 
later. We still need to hunt down snippets used that are not. 1324 modified

1aaa89aa9b Wow. Fix those irq #defines for ARM and use the right one in power-c200_e200.c. How'd that happen?

af395f4db6 Do core interrupt masking in a less general fashion and save some instructions to decrease size and speed things up a little bit. Small fix to a few places where interrupts would get enabled again where they shouldn't have been (context switching calls when disabled).

6077e5b7c8 Unify PCM interface just above the hardware driver level for all targets including the sims. Perform lockout of audio callback when changing states. Weird new playback or recording trouble? Check before and after this revision first though things seem quite sound.

4ae87c8b8a Gigabeat: Add timer functionality. Rework tick timer setup to be exactly 100Hz. Metronome should work now but some pcm changes are needed to have faster tocks work correctly (in the works).

7b861eca95 More PP502x clock setup rework. This should fix the freezes on PP5020 once and for all. Enabled clock scaling for H10. * CPUFREQ_MAX changed to 78MHz * To be cleaned up soon.
