[sw, mask_rom] Initialise Pinmux UART pins used to be dedicated, however with recent changes these became multiplexible. This means that in order to get any uart output in Mask ROM or ROM_EXT - the corresponding pins must be configured. This change adds call to pinmux_init at the beginning of mask_rom_boot. This ensures that the UART pins are configured in both Mask ROM and ROM_EXT. NOTE: DIF Pinmux is work in progress, however it is expected that Mask ROM will use the DIF directly to configure the pins. This also means that sw_lib_pinmux will cease to exist.

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.
