With the introduction of the SCMI (System Control and Management Interface), it is now possible to use the SCMI to handle the hold boot instead of a dedicated SMC call. As consequence two configurations are possible: - without SCMI server on OP-TEE: use the Linux rcc reset service and use syscon for the MCU hold boot - With SCMI server on OP-TEE: use the SCMI reset service for both the MCU reset and the MCU hold boot. This patch: - make optional and deprecated the use of the property st,syscfg-tz which was used to check if the trusted Zone was enable to use scm call, to manage the hold boot. The reset controller phandle is used instead to select the configurations. - make st,syscfg-holdboot optional - adds properties check on resets definitions. - adds an example of the SCMI reset service usage.

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.
