Subject: [PATCH RFC 09/12] RISC-V: crypto: update perl include with helpers for vector (crypto) instructions
From: Heiko Stuebner <heiko.stuebner@...ll.eu>
The openSSL scripts use a number of helpers for handling vector
instructions and instructions from the vector-crypto-extensions.
Therefore port these over from openSSL.
