[AON timer] Initial rtl commit This commit adds the basic timers, registers and CDC for the AON wakeup and watchdog timers. There is one functional change to the HJSON, which is to add a wakeup cause register. This register is written to zero by software to clear the wakeup request (similar to pinmux wakeup). CDC logic for register writes is currently not very sensible (a four entry async fifo for every register). There are TODOs covering this and it will be improved in subsequent updates.

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.
