[kmac] Clear the entropy in StRandEdn This commit addresses the issue #6393 reported by @udinator As the comment in the code explains, if SW initiates a new hash operation while the Entropy FSM is refreshing the internal entropy (waiting for the EDN response), the logic keeps sending same entropy to the hash logic. This commit fixed the behavior to clear the entropy valid signal if following logic consumes the entropy. Then, the logic will wait until the EDN response comes back.

OpenTitan is an open source silicon Root of Trust (RoT) project. OpenTitan will make the silicon RoT design and implementation more transparent, trustworthy, and secure for enterprises, platform providers, and chip manufacturers. OpenTitan is administered by lowRISC CIC as a collaborative project to produce high quality, open IP for instantiation as a full-featured product. See the OpenTitan site and OpenTitan docs for more information about the project.
This repository contains hardware, software and utilities written as part of the OpenTitan project. It is structured as monolithic repository, or “monorepo”, where all components live in one repository. It exists to enable collaboration across partners participating in the OpenTitan project.
The project contains comprehensive documentation of all IPs and tools. You can access it online at docs.opentitan.org.
