[otbn] Fix some issues in modexp assembly The modexp assembly doesn't currently run on the new simulator. Some problems are simulator-related, others are bugs in the code. I'm still going through all of them, but here are two fixes which are clearly wrong in the assembly. * LW expects offsets in bytes, not in 32b words. * In contrast to dcrypto1, routines need to end with an explicit ECALL instruction.

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.
