It seems a bit unnecessary for the PLPKS code to have a user-visible config option when it doesn't do anything on its own, and there's existing options for enabling Secure Boot-related features. It should be enabled by PPC_SECURE_BOOT, which will eventually be what uses PLPKS to populate keyrings. However, we can't get of the separate option completely, because it will also be used for SED Opal purposes. Change PSERIES_PLPKS into a hidden option, which is selected by PPC_SECURE_BOOT.

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.
