samples/audio: Add Sound Open Firmware Adds the Sound Open Firmware project, built as a Zephyr application, under samples/subsys/sudio/sof. Signed-off-by: Liam Girdwood <liam.r.girdwood@linux.intel.com>

samples/subsys/audio/sof: enable CONFIG_LOG_PRINTK Route printk()'s through logging subsystem. This is required to get clean OS panics in log output. If this is not defined, e.g. the stack backtrace is mixed with the Zephyr OS panic information. Signed-off-by: Kai Vehmanen <kai.vehmanen@linux.intel.com>

sof: remove superfluous and duplicate code 1. SOF doesn't have to be built in .bin format 2. don't include soc.c and soc_mp.c twice in cmake 3. remove an unused mailbox.h header Signed-off-by: Guennadi Liakhovetski <guennadi.liakhovetski@linux.intel.com>

ADSP / SOF: don't force uniprocessor mode Allow SMP processing for SOF on ADSP. Note, that after this SOF will build with SMP support enabled on all cAVS versions, but secondary cores will remain disabled unless an SMP topology is loaded by the host.

samples/subsys/audio/sof: build with CONFIG_SPEED_OPTIMIZATIONS The inner loops of SOF audio algorithms benefit from compiler optimizations. On Intel cAVS platforms, it was noted zero-overhead loops ("loop" family of instructions) is not used for fixed-size inner loops when using -Os (optimize for size) and the XCC xtensa toolchain.

samples/subsys/audio/sof: use -fstrict-overflow for SOF Align compiler flags of SOF Zephyr build with the build SOF XTOS and use -fstrict-overflow. With -fno-strict-overflow, some versions of XCC compiler (e.g. xt-xcc 12.0.8) always emit a "bltu" instruction to check for overflow in loops like: unsigned int n; for(n = 0; n < 1024; n++) do_arithmetic(); With "-fno-strict-overflow", you'll have: 18: 068076 loop a0, 22 <dummy_dspload+0x22> 1b: 445a add.n a4, a4, a5 1d: 551b addi.n a5, a5, 1 1f: 023657 bltu a6, a5, 25 <dummy_dspload+0x25> 22: fffc86 j 18 <dummy_dspload+0x18> With "-fstrict-overflow": 16: 038476 loop a4, 1d <dummy_dspload+0x1d> 19: 223a add.n a2, a2, a3 1b: 331b addi.n a3, a3, 1 As this is a common pattern in audio DSP code, change the default for SOF builds to -fstrict-overflow.

samples/subsys/audio/sof: fix sys-ticks-per-sec to 15000 The value of CONFIG_SYS_CLOCK_TICKS_PER_SEC has side-effects that are not expected with tickless kernel mode. In bug #46378, application code is shown to run slower with higher sys clock tick value. In SOF bug #5921, audio quality issues were root-caused to k_timer inaccuracy with 50000 sys clock tick. Set the the value to 15000 for all SOF applications. All existing test cases pass with this value.
