+ * CONTEXT_HUB_OS_REBOOT
+ * Reboots context hub OS, restarts all the nanoApps.
+ * No reboot notification is sent to nanoApps; reboot happens immediately and
+ * unconditionally; all volatile FW state and any data is lost as a result
+ *
+ * Payload : none
+ *
+ * Response : status_response_t
+ *            On receipt of a successful response, it is
+ *               expected that
+ *
+ *               i) system reboot has completed;
+ *                  status contains reboot reason code (platform-specific)
+ *
+ * Unsolicited response:
+ *            System may send unsolicited response at any time;
+ *            this should be interpreted as FW reboot, and necessary setup
+ *            has to be done (same or similar to the setup done on system boot)
