Hi, even though the comments were marked as resolved PRs usually still need explicit approval before being merged.

Would it be possible to revert this and open another PR so it can go through another round of review? Or was this reviewed internally within SiFive?

Unfortunately I don't think you can reopen merged PRs on GitHub
