58b2e45782 Fix unified syntax in ARM inline assembly 
GCC 4.9 always emits assembly with divided syntax. Setting unified
syntax in inline assembly causes the assembler to complain about
GCC's generated code, because the directive extends past the scope
of the inline asm. Fix this by setting divided mode at the end of
the inline assembly block.

The assembler directives are hidden behind macros because later
versions of GCC won't need this workaround: they can be told to
use the unified syntax with -masm-syntax-unified.

3ba2f6e5c7 Nuke all TCC77x targets: iAudio 7, Sansa C100, M200(v1-3), Logik DAX 
They were never finished, never saw any release ever, and haven't
compiled for the better part of a decade.  Given their HW capabilities [1],
they are not worth trying to fix.

[1] 1-2MB RAM, ~256MB onboard flash, no expandability

388adff3cc pcm: Further cleanup of unused bits of the PCM ACPI: 
* pcm_get_bytes_remaining()
 * pcm_calculate_peaks()
 * pcm_get_peak_buffer()

Nothing in-tree uses these at all (except for the lua plugin wrapper)

fe2d52cc7d pcm: Get rid of pcm_play_pause() and associated APIs 
Nothing in the core has used it for some time.  It's exported to the
plugin API but the last plugins to use it were switched to the mixer API
back in 2011.

This allows us to get rid of pcm_play_dma_pause() from all audio drivers

59e5a323f1 Fix errors in unintentionally merged gerrit commit. 
It proved the system work as unintended, even if slightly prematurely.
It was almost ready anyway.

286a4c5caa Revise the PCM callback system after adding multichannel audio. 
Additional status callback is added to pcm_play/rec_data instead of
using a special function to set it. Status includes DMA error
reporting to the status callback. Playback and recording callback
become more alike except playback uses "const void **addr" (because
the data should not be altered) and recording  uses "void **addr".
"const" is put in place throughout where appropriate.

Most changes are fairly trivial. One that should be checked in
particular because it isn't so much is telechips, if anyone cares to
bother. PP5002 is not so trivial either but that tested as working.

4db3e89652 Shuffle some functions around so that interfacing with playback.c in particular isn't required. Though playback does finish the audio init, pcm doesn't care who does it.

a2b6703a36 Commit FS#12150 - Fully-functional audio mixer - and finally whip old limitations about playback of voice and other sounds when paused. Channels are independent in state and amplitude. Fade on stop/pause is handled by the channel's volume control rather than global volume which means it now works from anywhere. Opens up the possibility of plugin sounds during music playback by merely adding an additional channel enum. If any PCM drivers were not properly modified, see one of the last comments in the task for a description of the simple change that is expected. Some params are tunable in firmware/export/pcm-mixer.h as well.

d56999890f Make PCM->driver interface about as simple as it will get. Registered callback, zero data, alignment and stops are handled entirely inside pcm.c; driver merely calls fixed pcm.c callback. Remove pcm_record_more and do it just like playback; the original reason behind it isn't very practical in general. Everything checks out on supported targets. There wer some compat changes I can't check out on many unsupoorted but if there's a problem it will be a minor oops. Plugins become incompatible due to recording tweak-- full update. Sorted API.

4d04132c76 PCM bottom layer simplification. pcm_rec_peak_addr variable no longer has to be handled there. Driver can just return current pointer for recording peaks. A new define, HAVE_PCM_REC_DMA_ADDRESS, specifies that physical addresses are being used for recording and translation is needed before starting a new block. The drivers need not worry about aligning start and size nor should care if either will be zero. All this will be checked in the logical layer first.

888451fb0f Get rid of remaining audiohw_enable_output style codec setup and use pre/post split initialization. Move some SoC-specific code like i2s_reset out of the codec drivers. Helps to unify drivers and it was only ever used to enable. I cannot possibly test everything so report (I'll be on call ;) or fix problems if any crop up.

85807cd44e Trivial changes to make the main Rockbox builds for the Sansa m200 and Logik DAX ports compile. Note that some codecs are currently disabled (due to lowmem on these targets), but that needs more work and analysis to decide how much RAM we want to allocate to codecs.
