Power off in Coreboot?

Folks,
We are working through the PMIC requirements for Coreboot on our 
hardware.
I understand the need for Coreboot to command a reboot, e.g. VerStage 
detects FW_A is bad and wants to try FW_B.
What is not clear is what is the use-case for Coreboot to command a 
power-off.

In grepping the sources I see the API is provided and only used in a 
handful of cases, mainly x86.

On an ARMv8 target is there a power-off use-case for Coreboot?
This is strictly from Coreboot perspective, not Depthcharge.
Cheers,
T.mike

You're right, there is no globally standardized power off API in coreboot,
it's only implemented internally by select chipsets. There is no ARM target
that implements something like this at the moment, because they don't
really need to.
