My bad, I should have provided the link in my previous response

Processor Programming Reference (PPR) for AMD Family 19h Model 01h, 
Revision B1 Processors

https://www.amd.com/system/files/TechDocs/55898_B1_pub_0.50.zip

look for the PPR_B1_PUB_1.pdf for RMP entry details.

SEV-SNP firmware spec is at developer.amd.com/sev
https://www.amd.com/system/files/TechDocs/56860.pdf

thanks
