Description

We have 3 register file implementations, one flip-flop based, one latch based and one targetting FPGA implementation. They all duplicate various bits of security hardening logic. The register files should be refactored so the security hardening logic is in a common module as much as is possible and keeping the per-implementation logic to a minimum.

Research direction

Locate the three register file implementations described in the issue and compare their duplicated security hardening logic. Refactor the shared logic into a common module while keeping implementation-specific logic minimal; done means the three implementations no longer duplicate the common hardening behavior.
