Add the sub-mailbox nodes that are used to communicate between MPU and various remote processors present in the J721E SoCs to the J721E EAIK board. These include the R5F remote processors in the dual-R5F cluster (MCU_R5FSS0) in the MCU domain and the two dual-R5F clusters (MAIN_R5FSS0 & MAIN_R5FSS1) in the MAIN domain; the two C66x DSP remote processors and the single C71x DSP remote processor in the MAIN domain. These sub-mailbox nodes utilize the System Mailbox clusters 0 through 4. All the remaining mailbox clusters are currently not used on A72 core, and are hence disabled. The sub-mailbox nodes added match the hard-coded mailbox configuration used within the TI RTOS IPC software packages. The R5F processor sub-systems are assumed to be running in Split mode, so a sub-mailbox node is used by each of the R5F cores. Only the sub-mailbox node for the first R5F core in each cluster is used in case of a Lockstep mode for that R5F cluster.

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.
