This is going right in since it's long overdue. If anything is goofed, drop me a line or just tweak it yourself if you know what's wrong. :-) Make HW/SW codec interface more uniform when emulating HW functionality on SWCODEC for functions such as "audiohw_set_pitch". The firmware-to- DSP plumbing is in firmware/drivers/audiohw-swcodec.c. "sound_XXX" APIs are all in sound.c with none in DSP code any longer. Reduce number of settings definitions needed by each codec by providing defaults for common ones like balance, channels and SW tone controls. Remove need for separate SIM code and tables and add virtual codec header for hosted targets. Change-Id: I3f23702bca054fc9bda40f49824ce681bb7f777b
