commit 1574051e52cb4b5b7f7509cfd729b76ca1117808 upstream. The Intel C620 Platform Controller Hub has MROM functions that have non-PCI registers (undocumented in the public spec) where BAR 0 is supposed to be, which results in messages like this: pci 0000:00:11.0: [Firmware Bug]: reg 0x30: invalid BAR (can't size) Mark these MROM functions as having non-compliant BARs so we don't try to probe any of them. There are no other BARs on these devices. See the Intel C620 Series Chipset Platform Controller Hub Datasheet, May 2019, Document Number 336067-007US, sec 2.1, 35.5, 35.6.

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.
