mainlining shenanigans
On newer CAAM versions, not all accelerators are disabled if the SoC is
a non-E variant. While the driver checks most of the modules for
availability, there is one - PKHA - which sticks out. On non-E variants
it is still reported as available, that is the number of instances is
non-zero, but it has limited functionality. In particular it doesn't
support encryption and decryption, but just signing and verifying. This
is indicated by a bit in the PKHA_MISC field. Take this bit into account
if we are checking for availability.
This will the following error:
[ 8.167817] caam_jr 8020000.jr: 20000b0f: CCB: desc idx 11: : Invalid CHA selected.
Tested on an NXP LS1028A (non-E) SoC.

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.
