Add PCIe RC support on Orion O6 board. The Orion O6 board includes multiple PCIe root complexes. The current device tree configuration enables detection and basic operation of PCIe endpoints on this platform. GPIO and pinctrl subsystems for this platform are not yet ready for upstream inclusion. Consequently, attributes such as reset-gpios and pinctrl configurations are temporarily omitted from the PCIe node definitions. Endpoint detection and functionality are confirmed to be operational with this basic configuration. The missing GPIO and pinctrl support will be added incrementally in future patches as the dependent subsystems become available upstream.

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.
