Add support for a new 'non CCA clear key token' with these ECC clear keys supported: - ECC P256 - ECC P384 - ECC P521 - ECC ED25519 - ECC ED448 This makes it possible to derive a protected key from this ECC clear key input via PKEY_KBLOB2PROTK3 ioctl. As of now the only way to derive protected keys from these clear key tokens is via PCKMO instruction. For AES keys an alternate path via creating a secure key from the clear key and then derive a protected key from the secure key exists. This alternate path is not implemented for ECC keys as it would require to rearrange and maybe recalculate the clear key material for input to derive an CCA or EP11 ECC secure key.

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.
