[mask_rom] Perform basic AST initialization Copy the configuration from OTP unconditionally and then poll the ast_init_done flag until it is set. Future commits will make this initialization more flexible. In particular we need to skip AST configuration if OTP is not yet programmed and also we need to add a timeout to the polling. Note that the open source AST model does not validate the configuration and ast_init_done is hardcoded in the RTL to 1. Signed-off-by: Michael Munday <mike.munday@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.
