Yurii Monakov 6700c0d9ae PCI: keystone: Fix outbound region mapping
commit 2d0c3fbe43fa0e6fcb7a6c755c5f4cd702c0d2f4 upstream.

The Keystone outbound Address Translation Unit (ATU) maps PCI MMIO space in
8 MB windows.  When programming the ATU windows, we previously incremented
the starting address by 8, not 8 MB, so all the windows were mapped to the
first 8 MB.  Therefore, only 8 MB of MMIO space was accessible.

Update the loop so it increments the starting address by 8 MB, not 8, so
more MMIO space is accessible.

Fixes: e75043ad97 ("PCI: keystone: Cleanup outbound window configuration")

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.
