Add a reserved memory node to reserve a portion of the DDR memory to be used for performing inter-processor communication between all the MCU R5F remote processors running RTOS on all the TI AM654 boards. This memory shall be exercised only if the MCU R5FSS cluster is configured for Split mode. A single 1 MB of memory at 0xa2000000 is reserved for this purpose, and this accounts for all the vrings and vring buffers between pair of these R5F remote processors.

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.
