As we setup the memory regions for the device, give each a quick test to verify that we can read and write to the full iomem range. This ensures that our physical addressing for the device's memory is correct, and some reassurance that the memory is functional. v2: wrapper for memtest [Chris] v3: Removed the unused ptr i915 [Chris] v4: used the %pa for the resource_size_t.

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.
