Make the DWC PCIe RC/EP safer and more verbose for invalid or failed inbound and outbound iATU window setups. Silently ignoring iATU regions setup errors may cause unpredictable errors. For instance if a cfg or IO window fails to be activated, then any CFG/IO requested won't reach target PCIe devices and the corresponding accessors will return platform-specific random values.

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.
