This patch adds debug support for imx platforms. This is important in order to gather information about the state of the DSP in case of an oops and the reason for the oops. This is done by checking if a message with a panic code has been placed in the debug box, in the imx8_dsp_handle_request function from sof/imx. If positive, the function imx8_dump, added in common, will be called. The first step is to gather information about the registers, filename, line number and stack by calling the imx8_get_registers, added in common. Then the information will be printed to the console by calling the get_status function.

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 Restructured Text 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.
