Moves inclusion of PLATFORM_INCDIR before SOF_INCDIR.
This temporarily fixes wrong inclusion of core-isa.h from
xtensa-root directory during build with gcc. It's the best
solution for now, because that unwanted header comes from
Xtensa Newlib C library, which will take much more time to change.

Let's remove reef to avoid confusion/legacy.
no functionality change but the name of generated files
will change so targets and install scripts will need
to be updated
There should be only one occurrence of "Reef" left in
rimage/file_format.h, left as is for backwards compatibility.
This may be changed separately at a later point.

Initialise the SA during platform init and then notify SA of idle in the
main audio loop.

Add an API to allow tasks to be added to the scheduler task list but not
run until the DSP enters an idle state. i.e. we schedule the task as normal
but dont immediately call schedule() to schedule that task for execution
and instead wait until schedule() is next called (at the end of some other
work).
This patch also calls schedule() before entering the idle state in the main
processing loop.

This change provides an IIR equalizer component. The
IIR equalizer can be used for any transducer or effects equalizer needs but
it is especially recommended for speaker response equalization and other
applications without dependence to matched phase response or best possible
THD+N performance where FIR may be a better choise. IIR equalization is
capable to strong response enhancement without need for large DSP resources
consumption. The tool to create the EQ setup blobs is included in the
rimage tools.
This change provides a finite impulse response (FIR)
equalizer component. The FIR equalizer can be used for any transducer or
effects equalizer needs but it is especially recommended for microphone
arrays equalization. The tool to create EQ setup blobs is included in the
rimage tools.
This change provides a tone generator component. The
purpose is to provide a high quality FW internal test signal generator for
objective audio quality measurements for component or system tests. It can
also be used as simple beep indication tones generator for users.
This change provides a sample rate converter (SRC).
The SRC is polyphase FIR type. All the conversions coefficients tables are
automatically generated by a separate Octave scripts set in the rimage
tools set. The supported in/out rates and the performance can be customized
for a different quality/resources trade-off.
Currently pipelines have to be statically defined in the firmware source
code. This patch provides a mechanism whereby they can be created and
destroyed via IPC messages from the host.
Part 2 to follow.

Create a global firmware context structure and pass this to each subsystem
on initialisation. This allows components to share access to global DSP
context.

This project provides an open source audio firmware infrastructure for audio
DSPs found on many modern devices. The intention is to allow developers to
create their own codecs, audio processing algorithms and pipelines using
the infrastructure and audio components provided by this project.
The project currently supports the Intel Baytrail and Cherrytrail audio DSP
platforms which use the Xtensa architecture.
The firmware source code is released under the BSD 3 clause licence.
