We only need handle host page tables on platforms that we
program DMA host buffer(addr/size) inside firmware, for
other platforms, host driver will program these settings
and won't pass in page tables.
So here add frag CONFIG_HOST_PTABLE to configure this for
different platforms, on Baytrail, Cherrytrail, we need
CONFIG_HOST_PTABLE to be selected.

For debug reason, e.g. DMA trace doesn't work or not implemented
yet, we can use --disable-dma-trace in configure command line,
which will unset CONFIG_DMA_TRACE flag, and it will fallback
to use traditional mailbox trace instead.
The flag is set by default, if we don't add '--disable-dma-trace'
to configure command.

gcc -Wall is not enough, add -Wmissing-prototypes to align with
kernel warnings.
Add relevant includes and move functions without prototype as static

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.
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

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

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.
