Now that the JR0 reservation is done in both upstream (v2.7) and downstream (NXP lf_v2.4) TF-A versions, the kernel fails to initialize the job ring 0: # dmesg | grep jr caam_jr 30901000.jr: failed to flush job ring 0 caam_jr: probe of 30901000.jr failed with error -5 Disable the sec_jr0 nodes by default to avoid the caam_jr probe error.

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.
