Make the mixer compute two channels per loop iteration. This allows for
easier vectorisation. The loop is also more efficient if we update or
source/sink pointers after mixing has completed.

The conversion should up/down convert only if source/sink is host or dai.
Volume should be 32 bit at all other times

Use period frames instead of period size in bytes. This makes the pipeline
configuration less ambiguous and also allows for host, dai and internal frame
sizes to be defined.

Host buffers are not guaranteed to be continuous physical pages or a factor
of the DSP period size. Add support for non continuous host buffers of any
size.

The host buffer may not be a multiple of host PHY page size, so provide
so pass this value as part of our host buffer init.

Add support to immediately reload the DMA during a DMA transfer completion
callback. This allows components to respond quickly to any physical
DMA copy updates i.e. period split over two non continuous physical host
pages.

switch the BCLK generation from shim ssp clock divider to
using SSCR0.SCR, as the divider may lead to jitter.
clear and remove M/N divider part code.

for DMA controller, we need mask dsp local memory before
setting it to DMAC registers, otherwise, DMAC will locate
to wrong memory address.

We need clear/reset buffer content to 0s each time
creating a pipeline buffer, to avoid random noise
when using it.

In order to use native XTENSA compiler the core target needs to
be overwite with the good platform. This patch is adding an optional
option in order to be able to overwrite the core selection.
Example:
- Set Xtensa export PATH=$PATH:<PATH>/xtensa/XtDevTools/install/tools/RD-2012.5-linux/XtensaTools
./configure --with-arch=xtensa --with-platform=baytrail --with-dsp-core=CHT_audio_hifiep --with-root-dir=<PATH>/xtensa/XtDevTools/install/tools/RD-2012.5-linux/XtensaTools --host=xtensa CC=xt-xcc OBJCOPY=xt-objcopy OBJDUMP=xt-objdump
make
make bin

On the linux driver side, it need get version infomation
from fw, including:
type -- Reef
version -- major.minor
build number
last commit id -- gID
So here we use the package string, which come from git
version, which can provide all those fw version infos.

We are using 6 states, 2 of them are substates:
init, idle, running, paused,
draining(sub state when transferring from running to idle)
pausing(substate when transferring from running to paused).
Don't response new command when in substates, only stay in
substates for limited timeout. e.g. 2ms for draing and 1ms
for pausing.

The tool-dir naming was a bit ambiguous so rename and fix build-all.sh
to use new name too.

The DMA controller needs to differentiate between host and DSP memory
regions. This can be done with a mask that is ORed with local DSP memory
locations.

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.
