Practically all modern Qualcomm platforms has a single reserved-memory region for SMEM. So rather than having to describe SMEM in the form of a node with a reference to a reserved-memory node, allow the SMEM device to be instantiated directly from the reserved-memory node. The current means of falling back to dereferencing the "memory-region" is kept as a fallback, if it's determined that the SMEM node is a reserved-memory node. The "qcom,smem" compatible is added to the reserved_mem_matches list, to allow the reserved-memory device to be probed. In order to retain the readability of the code, the resolution of resources is split from the actual ioremapping.

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.
