On a PLPKS enabled PowerVM LPAR, the secvar format property for static key management is misrepresented as "ibm,plpks-sb-unknown", creating reason for confusion. Static key management mode uses fixed, built-in keys. Dynamic key management mode allows keys to be updated in production to handle security updates without firmware rebuilds. Define a function named plpks_get_sb_keymgmt_mode() to retrieve the key management mode based on the existence of the SB_VERSION property in the firmware. Set the secvar format property to either "ibm,plpks-sb-v<version>" or "ibm,plpks-sb-v0" based on the key management mode, and return the length of the secvar format property.

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 reStructuredText 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.
