PSCI is an interface for calling into power management firmware.
Just saying that *a* PSCI call failed is not informative, we really need the arguments of the call.

I'm not sure what firmware you have on the SD card but armstub8 from
https://github.com/gonzoua/rpi3-psci-monitor should support:
PSCI_VERSION, PSCI_CPU_ON, PSCI_SYSTEM_OFF, and PSCI_SYSTEM_RESET.
Which should be all the calls that FreeBSD ever does…
