The Xilinx Versal Premium series has CPM5 block which supports Root Port
functioning at Gen5 speed.
Xilinx Versal CPM5 has a few changes from the existing CPM block:
- CPM5 has dedicated register space for control and status registers.
- CPM5 legacy interrupt handling needs additional register bit to enable
and handle legacy interrupts.
Add support for the new CPM5 features.
[bhelgaas: compare variant->version with CPM5 explicitly]

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.
