It is my understanding that Heiko is taking a break from development, I
don't think he will be working on this soon.

Our proposed implementations is under reviewing in OpenSSL pr.
And I will check the gluing parts between Linux kernel and OpenSSL.

The OpenSSL PR is at [1].
And we are from SiFive.
