[sw,otbn] Add OTBN code snippet for P-384 Solinas reduce. Adds a small code snippet demonstrating Solinas modular reduction algorithm for P-384. This implementation takes 86 cycles for a modular multiplication and full reduction, or 46 cycles for a modular reduction alone. It compares favorably to a generic Barrett implementation, which takes 150 cycles for multiplication and reduction (1.76x speedup) and 110 for a reduction alone (2.39x speedup).

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.
