The definition of 'struct sof_dev_desc' has the following properties
for imx chips:
1) FW path is the same for all chips.
2) Topology path is the same for all chips.
3) FW name can be written as: "sof-${machine_name}.ri"
4) IPC3 is the only supported protocol
The structure takes quite a few lines of code. Since the intention
is to add support for more imx8 chips in the same driver, we need
to try and reduce the number of lines taken by information that's
not particularly useful. As such, we can use 'IMX_SOF_DEV_DESC()'
to reduce the declaration of the structure to just one line. The
only information that's particularly useful can be seen from the
parameters of the macro.
Of course, if any of the assumptions don't apply anymore, driver
writers can simply declare the 'struct sof_dev_desc' the "old
fashioned way". No reason to make the macro suit multiple needs.
The same logic applies to the array of 'struct snd_soc_dai_driver'.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
