.. note::
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.
