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 an MRQ, for which a service routine will be run when a
corresponding event is received from the firmware.

MRQ?

I think that means "Message ReQuest", which is sort of like an IRQ but
the user will receive a message (with potentially payload) instead. Do
you want me to spell that out in the commit message, or what would you
suggest?

I believe MRQ refers to the ID/type/semantics of the message structure 
itself, not so much the notification aspect of having received a message.
