[mask_rom] HMAC driver fixes for digest reading and endianness This change fixes `hmac_sha256_init` and `hmac_sha256_final` to match the output of `openssl` and `sha256sum` and preserve the numerical value of the digest. It also fixes IRQ clearing in these functions so that the driver can be used more than once. This is required to be able to verify the second slot if the first one does not succeed.

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.
