SMCCC v1.0 lacked discoverability of version and features. To accelerate adoption of few mitigations and protect systems more rapidly from various vulnerability, PSCI v1.0 was updated to add SMCCC discovery mechanism though the PSCI firmware implementation of PSCI_FEATURES(SMCCC_VERSION) which returns success on firmware compliant to SMCCC v1.1 and above. This inturn makes SMCCC v1.1 and above dependent on ARM_PSCI_FW for backward compatibility. Let us introduce a new hidden config for the same to build more features on top of SMCCC v1.1 and above. While at it, also sort alphabetically the psci entry.

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.
