K3 devices introduces the concept of centralized power, resource and security management to System Firmware. This is to overcome challenges by the traditional approach that implements system control functions on each of the processing units.
The software interface for System Firmware is split into TIFS and DM. DM (Device Manager) is responsible for resource and power management from secure and non-secure hosts. This additional binary is necessary for specific platforms' ROM boot images and is to be packaged into tispl.bin
Add an entry for DM. The entry can be used for the packaging of tispl.bin by binman along with ATF and TEE.
