[ Upstream commit 62f95ae805 ]
Newer combinations of the glibc, kernel and openssh can result in long initial
startup times on OMAP devices:
[ 6.671425] systemd-rc-once[102]: Creating ED25519 key; this may take some time ...
[ 142.652491] systemd-rc-once[102]: Creating ED25519 key; done.
due to the blocking getrandom(2) system call:
[ 142.610335] random: crng init done
Set the quality level for the omap hwrng driver allowing the kernel to use the
hwrng as an entropy source at 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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
