Description

The KMAC hardware block is only going to be used to check the contents of the ROM, so we can save power by disabling it (stopping its clock) once that the check is complete and the core starts fetching instructions.

Research direction

Trace the KMAC ROM-check completion signal and the transition where the core begins fetching instructions. Stop the KMAC clock only after the check completes, then verify that instruction fetching still starts normally and the KMAC block remains disabled.
