In the olden days the Qualcomm shared memory (SMEM) region consisted of multiple chunks of memory, so SMEM was described as a standalone node with references to its various memory regions. But practically all modern Qualcomm platforms has a single reserved memory region used for SMEM. So rather than having to use two nodes to describe the one SMEM region, update the binding to allow the reserved-memory region alone to describe SMEM. The olden format is preserved as valid, as this is widely used already.

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.
