Marcos Del Sol Vives 72ee532421 PCI: Disable MSI on RDC PCI to PCIe bridges
[ Upstream commit ebc7086b39e5e4f3d3ca82caaea20538c9b62d42 ]

RDC PCI to PCIe bridges, present on Vortex86DX3 and Vortex86EX2 SoCs, do
not support MSIs. If enabled, interrupts generated by PCIe devices never
reach the processor.

I have contacted the manufacturer (DM&P) and they confirmed that PCI MSIs
need to be disabled for them.

README

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.
