Pali Rohár 7f71a409fe PCI: aardvark: Implement workaround for the readback value of VEND_ID
Marvell Armada 3700 Functional Errata, Guidelines, and Restrictions
document describes in erratum 4.1 PCIe value of vendor ID (Ref #: 243):

    The readback value of VEND_ID (RD0070000h [15:0]) is 1B4Bh, while it
    should read 11ABh.

    The firmware can write the correct value, 11ABh, through VEND_ID
    (RD0076044h [15:0]).

Implement this workaround in aardvark driver for both PCI vendor id and PCI
subsystem vendor id.

This change affects and fixes PCI vendor id of emulated PCIe root bridge.
After this change emulated PCIe root bridge has correct vendor id.

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.
