[sw/dif] Add tests for HMAC DIF This change adds some simple hardware smoke tests for the HMAC DIF. These tests perform the following checks/actions: 1. Configure the HMAC engine. 2. Push a message into the HMAC engine. 3. Check that the HMAC engine is reporting the correct message length. 4. Kick off a run of HMAC/SHA256. 5. Read the digest and compare the result to the expected result. This test is run in both HMAC and SHA256-only modes. The purpose of these tests is to provide some basic sanity checks on hardware and to serve as a working example of how to interface with the DIF. Unit tests of the HMAC DIF are to follow.

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.
