[otbn] Adjust BN.LID/BN.SID/BN.MOVR encoding As these use indirect addressing grd register field is moved to the field used for grs2 in all other instructions as the given grd value becomes a base side register to read to generate a bignum side register index for the destination register. BN.SID has no destination but the grs2 register field is moved to match with all other instructions (and so the offset and inc fields match up with BN.LID/BN.MOVR).

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.
