Two carveout reserved memory nodes each have been added for each of the R5F remote processor device within both the MCU and MAIN domains for the TI K3 AM69 SK boards. These nodes are assigned to the respective rproc device nodes as well. The first region will be used as the DMA pool for the rproc device, and the second region will furnish the static carveout regions for the firmware memory. The current carveout addresses and sizes are defined statically for each device. The R5F processors do not have an MMU, and as such require the exact memory used by the firmwares to be set-aside. The firmware images do not require any RSC_CARVEOUT entries in their resource tables either to allocate the memory for firmware memory segments. Note that the R5F1 carveouts are needed only if the R5F cluster is running in Split (non-LockStep) mode. The reserved memory nodes can be disabled later on if there is no use-case defined to use the corresponding remote processor.

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.
