So far I wasn't aware of the remoteproc API. It appears to me that is
limited to power on/off and loading firmware in an AMP scenario. Here,
the Companion has a fixed firmware in it. It must already be running
quickly after power-up, even before the boot loader.

Does remoteproc also contain a communication framework?

Do you mean rpmsg? Here, I do not see how we could benefit from it.

Can you point me to an example where rpmsg is used over SPI?

Greetings,
Mark
