Current trusted keys framework is tightly coupled to use TPM device as an underlying implementation which makes it difficult for implementations like Trusted Execution Environment (TEE) etc. to provide trusted keys support in case platform doesn't posses a TPM device. Add a generic trusted keys framework where underlying implementations can be easily plugged in. Create struct trusted_key_ops to achieve this, which contains necessary functions of a backend. Also, define a module parameter in order to select a particular trust source in case a platform support multiple trust sources. In case its not specified then implementation itetrates through trust sources list starting with TPM and assign the first trust source as a backend which has initiazed successfully during iteration. Note that current implementation only supports a single trust source at runtime which is either selectable at compile time or during boot via aforementioned module parameter.

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.
