Currently arm64 doesn't initialize the primary CRNG in a (potentially) trusted manner as we only detect the presence of the RNG once secondary CPUs are up. Now that the core RNG code distinguishes the early initialization of the primary CRNG, we can implement arch_get_random_seed_long_early() to support this. This patch does so.

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.
