[ Upstream commit c9cca7034b34a2d82e9a03b757de2485c294851c ]
The MPC885 reference manual states:
SEC Lite-initiated 8xx writes can occur only on 32-bit-word boundaries, but
reads can occur on any byte boundary. Writing back a header read from a
non-32-bit-word boundary will yield unpredictable results.
In order to ensure that, cra_alignmask is set to 3 for SEC1.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
