The OMAP remoteproc driver has been enhanced to parse and store the kernel mappings for different internal RAM memories that may be present within each remote processor IP subsystem. Different devices have varying memories present on current SoCs. The current support handles the L2RAM for all IPU devices on OMAP4+ SoCs. The DSPs on OMAP4/OMAP5 only have Unicaches and do not have any L1 or L2 RAM memories. IPUs are expected to have the L2RAM at a fixed device address of 0x20000000, based on the current limitations on Attribute MMU configurations. NOTE: The current logic doesn't handle the parsing of memories for DRA7 remoteproc devices, and will be added alongside the DRA7 support.

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.
