Use the io_no.h IO access support for all ColdFire systems, no matter whether configured with MMU enabled or disabled. Previously there was subtle differences in IO access functions used in both cases, and these resulted in broken behavior for some drivers. As observed and reported by Angelo when using MMU enabled systems the read/write family of functions was using little endian access, while the non-MMU enabled systems were using native endian. This results in drivers that are shared across Freescale processors (for some of the common internal SoC peripherals) not working - since they are wired up for native endian access. This problem brings to light issues with PCI bus access and local peripheral access - but these are not addressed with this fix.

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.
