[ Upstream commit 6b7330303a ]
Certain platforms like K2G reguires the outbound ATU window to be
aligned. The alignment size is already present in mem->page_size.
Use the alignment size present in mem->page_size to configure an
aligned ATU window. In order to raise an interrupt, CPU has to write
to address offset from the start of the window unlike before where
writes were always to the beginning of the ATU window.

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.
