[otbn] Change how we describe valid ranges for PC-relative operands It used to look something like this: Valid range: .-1048576 to .+1048574 in steps of 2 And is now expanded quite a lot to be super-explicit: Valid range: -1048576 to 1048574 in steps of 2. This is encoded PC-relative but appears as an absolute value in assembly. To write a raw value in an assembly file, write something in the range .-1048576 to .+1048574.

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.
