Two carveout reserved memory nodes have been added for the lone C71x DSP remote processor device present within the MAIN voltage domain for the TI J721E EVM boards. These nodes are assigned to the respective rproc device node 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 C71x DSP processor does support a MMU called CMMU, but is not currently supported and as such requires the exact memory used by the firmware to be set-aside. The firmware images currently do not need any RSC_CARVEOUT entries either in their resource tables to allocate the memory for firmware memory segments. The reserved memory nodes can be disabled later on if there is no use-case defined to use the C71x DSP remoteproc 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.
