[otbn] Add a "clear" input to otbn_stack This doesn't do anything except zero the write pointer. We're eventually going to add some sort of secure wipe, which will splat the stack contents. It might also do a 2-stage wipe of the write pointer, in which case this will take a bit more cleverness. For now, this change is just to allow functional correctness (clear the x1 stack on start) for testing. Signed-off-by: Rupert Swarbrick <rswarbrick@lowrisc.org>
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.
