[opentitantool] Persistent session support This change introduces a `opentitansession` command. `opentitansession --conf ... --interface ...` will start a new persistent session process, which would load the given configuration files and connect to the given physical interface. Default transport in absense of `--interface` has been changed to be "proxy" on `localhost:9900`, such that manual one-off manipulation can be done with the shortest possible command line. Configuration files are loaded as part of the session process startup, meaning that aliases can be used in the `gpio read` command above, without each individual invocation needing `--conf ...`. Forwarding of GPIO, UART and SPI has been verified with UltraDebug and Andreiboard: `opentitantool bootstrap` and `opentitantool console` works. Simulation transports such as Verilator or Ti50 host emulation would create a simulation environment as part of the constructor for their implementation of the `Transport` trait. Large parts of the asynchronous socket code has been copied from host emulation code in the Ti50 repository, developed by Semihalf. For now, the session process will continue running in the foreground, (unless shell primitives are used). A followup will enable proper daemon functionality, with .pid files, etc. Signed-off-by: Jes B.

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.
