[otbn] Pass lc_escalate as lc_tx_t to otbn_controller Instead of flattening the lifecycle escalate input at the top-level `otbn` module to a single bit and passing this bit down, this commit passes the multi-bit lifecycle escalate input to the FSM in `otbn_controller`, where it is then processed. This should be more difficult to attack. Signed-off-by: Andreas Kurth <adk@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.
