b15a523870 e200v1/c200v1: Implement limited samplerate switching. Rates 24kHz and below are being a bear as far as minor crackling at higher amplitude-- leave them out for the time being since no solution is currently evident. 48, 44, 32 (rec rates 24, 22, 16) seem perfectly fine. I'm betting c200 is ok to include because it uses the same setup as e200.

fc570147e6 Philips SA9200: initialize i2c, i2s, and as3514 as the OF does. Fixes clicks/pops heard when reading the adc.

6c399b8254 Use DMA for audio playback on PP502x (FS#9910 + some further mods). I can't say at this point about any change in battery life but it frees up a percent or two of CPU cycles as measured in the buffering screen. No change in recording transfers yet. Testing seemed to check out so put it out for general use and see what happens.

e69d567d9e Bring consistency to pcm implementation and samplerate handling. Less low-level duplication. A small test_sampr fix so it works on coldfire again.

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

a5d3029c82 Update source files to include the header file for the functions they implement, to make sure the header and the implementation is consistent (and fix it for a case where it wasn't).

782aae4402 Finish the conversion to packed i2s for PP502x. Karl Kurbjun-approved for Mini-1G. Simplify the pcm format selection #ifdefs.

1092edf3e1 Packed I2S for ipod Color (tested) and ipod 4G (untested, but assumed to be the same as the Color - everything else is).

ce135909b9 Change c200 and e200 to use the same IIS FIFO format as seems to be working for others. Samples there have been packed for a long time though so no change to that.

856ca78110 Use halfword IIS FIFO mode for H10. Won't save interrupts but seems it should be the DMA compatible mode. Setup pcm-pp.c to ease evaluating setting up PortalPlayer targets for DMA audio and for building an inventory of proper I2S settings and transfer sizes for all.

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.

940e8990b5 PP502x: Make RAM physical addresses uncached. Cache the flash ROM on targets with one. Kill all the now unneeded cache flushing and i2s tweaking on e200 so clicking is no worry. Write the driver framebuffer at uncached addresses. Recording monitoring may be a little noisy in the left channel for the moment when not boosted and will be addressed. All seems to work as advertised including flash ROM dump.

6dd3f449b3 I2S buffer level adjustment is not necessary on c200 as there is no memory mapped framebuffer that requires constant cache flushing like on e200.

dbc6b4e39a Sansa c200 port. Rockbox works with sound. Several features are disabled including some lcd options, FM radio, recording, and all plugins. Loading the OF from the Rockbox bootloader does not work.

e7075db2a7 e200: Use 16-16 L-R pairs when writing to the TX FIFO. Kill the channel swapping and clicks. Reduce number of FIQs. Should be adaptable to iPods and other PP targets in a few minutes work, eh?
