[sw/dif] Add FW override support to entropy src. The entropy src allows the firmware to disconnect the raw entropy from the pre-conditioner block at the output of the health checks. This allows firmware to access raw entropy. The firmware can also write data into the pre-conditioner block to provide firmware-controlled entropy at the output of the entropy src. This functionality can be useful to implement KAT tests of the pre-conditioner block. Signed-off-by: Miguel Osorio <miguelosorio@google.com>
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.
