[kmac] Add Main State Machine This commit adds main state machine at the KMAC top and add `in_progress` and `in_keyblock` signals for the entropy generation logic to refresh the entropy. The entropy logic uses in_progress signal to refresh the LFSR seed. in_keyblock signal let entropy logic to refresh the entropy everytime it is consumed, if not in keyblock state, entropy logic gives randome value and not changed by consumed signal.

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.
