 From the first look it looks like SCMI. Why do you introducing something what 
can be replaced by SCMI?
And SCMI has only specific ARM transport layer but the rest is arch independent.

In our case where we have Microblaze V in programmable logic I can't see any 
reason to use RPMI for talking to the same server if I need to do it from ARM 
side too via SCMI.

I pretty much think that there should be communication with ARM and instead of 
creating another firmware interface talk to each other and have only one which 
can be used across multiple architectures.
