[sw, rom_ext_signer] Add signing and remaining image update API
- Retrieving exponent is work-in-progress, and at the moment
dummy hardcoded vector of `0xA5` is used.
- Retrieving modulus is work-in-progress, and at the moment
dummy hardcoded vector of `0xA5` is used.
- Peripheral Lockdown Info encodingis work in progress, and at
the moment dummy hardcoded vector of `0xA5` is used.
- It is not clear yet how the device_usage_value is encoded in
the 256-bit usage_constraints blob, and at the moment dummy
hardcoded vector of `0xA5` is used.
This change adds image signing functionality through Mundane.
* There was some refactoring done, missing fields
`extension{0,1,2,3}_offset` have been added.
* `image_length` is no longer passed in the config, as it is
set automatically in the manifest assembly file.
* `image_timestamp` is no longer passed in the config, and is
calculated at runtime.

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.
