[ Upstream commit2b9f217433] The outbound windows (PCIEPAUR(x), PCIEPALR(x)) describe a mapping between a CPU address (which is determined by the window number 'x') and a programmed PCI address - Thus allowing the controller to translate CPU accesses into PCI accesses. However the existing code incorrectly writes the CPU address - lets fix this by writing the PCI address instead. For memory transactions, existing DT users describe a 1:1 identity mapping and thus this change should have no effect. However the same isn't true for I/O.

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.
