[PATCH v2 0/3] RISC-V: Add CSRs for several supervisor extensions

[Tsukasa OI]

v1:
<https://sourceware.org/pipermail/binutils/2022-February/119858.html>

This patchset adds CSRs for following extensions:

-   Smstateen
-   Sscofpmf
-   Sstc

For consistency with CSR_CLASS_I hypervisor-related CSRs, minimum
privileged specification on hypervisor-related CSRs are 1.12 and non
hypervisor-related CSRs are 1.9.1 (minimum supported; Smstateen and
Sstc) or none (Sscofpmf; which has no hypervisor-related CSRs).

This decision corresponds Option A on:
<https://sourceware.org/pipermail/binutils/2022-February/119874.html>

I have been busy since submitting v1 and I completely forgot to submit
v2 (which is already completed on February).

Thanks,
Tsukasa
