[flash_ctrl] update `IPoly` parameter in flash scrambler While working on #9322, I noticed the GF(2) irreducible polynomial used for the flash scrambling scheme was not the Conway polynomial with degree 64, but rather the Conway polynomial with degree 32. After discussion in #17443, it was determined that while OK, as the polynomial was still irreducible, a better, NIST recommended polynomial should be used instead. This updates the GF(2) irreducible polynomial used by the flash scrambler to the NIST recommended polynomial for block ciphers: `x^64 + x^4 + x^3 + x + 1`.

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.
