Robin Murphy f4ac7292b6 perf/arm-cmn: Support CMN-600AE
[ Upstream commit 12a94953c3 ]

The functional safety features of CMN-600AE have little to no impact on
the PMU relative to the base CMN-600 design, so for simplicity we can
reasonably just treat it as the same thing. The only obvious difference
is that the revision numbers aren't aligned, so we may hide some aliases
for events which do actually exist, but those can still be specified via
the underlying "type,eventid" format so it's not too big a deal.

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.
