I won't say you are wrong but the reason why it's named arm_scpi is
because the protocol was developed by ARM. It doesnn't mean only
ARM/ARM64 needs to use it, it can be used on any architecture for
inter-processor communication using any communication technique
(currently mailbox is the only supported in the driver)
