+
+ The TI Firmware required for functionality of the system can be
+ one of the following combination (see platform specific boot diagram for
+ further information as to which component runs on which processor):
+
+ * **TIFS** - TI Foundational Security Firmware - Consists of purely firmware
+ meant to run on the security enclave.
+ * **DM** - Device Management firmware also called TI System Control Interface
+ server (TISCI Server) - This component purely plays the role of managing
+ device resources such as power, clock, interrupts, dma etc. This firmware
+ runs on a dedicated or multi-use microcontroller outside the security
+ enclave.
+
+ OR
+
+ * **SYSFW** - System firmware - consists of both TIFS and DM both running on
+ the security enclave.
