The OMAP remote processors send a special mailbox message (RP_MBOX_CRASH) when they crash and detect an internal device exception. Add support to the mailbox handling function upon detection of this special message to report this crash to the remoteproc core. The remoteproc core can trigger a recovery using the prevailing recovery mechanism, already in use for MMU Fault recovery.

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.
