The AM62x and AM64x SoCs of the TI K3 family has a Cortex M4F core in the MCU domain. This core is typically used for safety applications in a stand alone mode. However, some application (non safety related) may want to use the M4F core as a generic remote processor with IPC to the host processor. The M4F core has internal IRAM and DRAM memories and are exposed to the system bus for code and data loading. A remote processor driver is added to support this subsystem, including being able to load and boot the M4F core. Loading includes to M4F internal memories and predefined external code/data memories. The carve outs for external contiguous memory is defined in the M4F device node and should match with the external memory declarations in the M4F image binary. The M4F subsystem has two resets. One reset is for the entire subsystem i.e including the internal memories and the other, a local reset is only for the M4F processing core. When loading the image, the driver first releases the subsystem reset, loads the firmware image and then releases the local reset to let the M4F processing core run.

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 reStructuredText 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.
