Before running the final build, apply the following change to the Linux kernel device tree.
The ``audioreach-kernel`` package includes the ``q6apm_audio_mem`` driver, which manages shared
memory between the APPS processor and the ADSP. This driver probes on the ``qcom,q6apm-dais``
compatible string to enable the audio memory device node.

Use ``devtool modify`` to check out the kernel source into the workspace:

.. code-block:: bash

devtool modify virtual/kernel

In ``<yocto_build_root>/sources/linux-imx/arch/arm64/boot/dts/freescale/imx8mp-evk-dsp.dts``,
add the following inside the root ``/ { }`` block:

.. code-block:: dts

q6apmdai: dais {
compatible = "qcom,q6apm-dais";
};

Once the configuration is complete, run the following command to generate the full build with
the integrated AudioReach components:
