AMD introduced the next generation of SEV called SEV-SNP (Secure Nested
Paging). SEV-SNP builds upon existing SEV and SEV-ES functionality while
adding new hardware security protection.
Define the commands and structures used to communicate with the AMD-SP
when creating and managing the SEV-SNP guests. The SEV-SNP firmware spec
is available at developer.amd.com/sev.
[ mdr: update SNP command list and SNP status struct based on current
spec, use C99 flexible arrays, fix kernel-doc issues. ]
