There are three separate series here:

 1. Smoke test support for SNP
 2. Negative tests for SEV+
 3. Prefault tests for SEV+

#3 likely has a dependency on #1, and probably on #2 as well (for style if nothing
else).  But that's really just an argument for focuing on #1 first, and the moving
onto the others once that's ready to go.
