[util,bazel] integrate flash scrambling with bazel This integrates the flash scrambling script with Bazel to enable pre-scrambling flash images before they are backdoor loaded in DV and Verilator simulations. A key feature to enable such is to pass the OTP VMEM image to the flash scrambling script so the flash scrambling key seeds, and enablement flag, can be read out and decoded for use. While this commit reads out the scrambling key seeds, they still must be processed to produce the actual scrambling keys (as is done in HW). Additionally, the scrambling enablement flag must be read to determine whether or not to enabling scrambling within the pre-preprocessing script. These will both happen in a follow up.

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.
