I have been in CC on U-Boot RPMI patches which got to my attention because
I don't want to have another interface for MB-V(riscv-) running in programmable 
logic and have another server in the system doing the same thing.

Based on that we had discussed about it with Vincent and Souvik (we missed you 
there) about using SCMI on non ARM platform and both of them didn't see the 
concern to be marked as ARM only protocol.
Truth is that some of protocols have ARM in description, file names, etc but 
some of them not. That's why I think it is good time to sync it up and enable
running this protocol on other SOCs.

I don't think it is going to be a big problem because it is just git mv which 
git is able to gracefully handle.
