The Boot and Power Management Processor (BPMP) is a co-processor found on Tegra SoCs. It is designed to handle the early stages of the boot process and offload power management tasks (such as clocks, resets, powergates, ...) as well as system control services. Compared to the ARM SCPI, the services provided by BPMP are message- based rather than method-based. The BPMP firmware driver provides the services to transmit data to and receive data from the BPMP. Users can also register a Message ReQuest (MRQ), for which a service routine will be run when a corresponding event is received from the firmware. A set of messages, called the BPMP ABI, are specified for a number of different services provided by the BPMP (such as clocks or resets).
