[kmac] Revise the endianness in KMAC Previous commit 00310851134f35124264a55458a9fc9b1e48d645 fixed the ordering issue. Based on the update, the KMAC top is revised w.r.t the reverted endianness in MSG_FIFO. The CFG.msg_endianness represents little-endian if the value is 0. The KMAC top, however, byte-swapped the TL input data and mask if 0. Also, the msg_endianness describes the value to affect secret keys. So, the design is updated accordingly.

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.
