The specification states (maintained by the RVI program managers) can
be found here:
https://wiki.riscv.org/display/HOME/Specification+Status
The AIA specification is in the state "Freeze Arch Review Complete"
with version "0.3.1-draft.32".
However, the public review period has not started yet.
I assume this will happen in the next 1-2 weeks (Anup probably knows better).
Ratification will then happen after the 45 days public review period.
Would the beginning of the public review period be acceptable for merging?
This patch needs a v2 anyway because I missed the Hypervisor and VS CSRs.
