This patch adds support for the SkyLake and KabyLake code loader on top of the SOF IPC4. The work was initially contributed in 2018 by Liam Girdwood and Zhu Yingjiang, and abandoned due to firmware signature issues. With the existing support of IPC v4, it's time to re-add this capability. This patch uses the newly added FSR (Firmware State Register) definitions for DSP state handling and targeting, ass well as new state definition for SKL which indicates that the firmware has been started (similar to FW_ENTERED on other platforms).

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.
