These comments are generated by Copilot (Claude Sonnet 4.5) and should be checked, but they do seem legit. This is a preliminary action to reproduce a similar programming interface as XIF in a memory-mapped (hwpe-ctrl) setting.
This renewed register interface mimics identical structure to the XIF that is currently the only supported one on the development branch of RedMulE.
…to redmule_top Also, propagate target_clear to the controller when using HWPE_TARGET interface (XIF currently does not provide a software-based soft clear mechanism, which is a significant liability...)

This pull request reintroduces a memory-mapped register interface for RedMulE, based on a SystemRDL specification. The changes include a SystemRDL file that describes the register map, a script to generate SystemVerilog and C header outputs using PeakRDL, and integration of the generated interface into the hardware design.
The register interface follows the same structure of the XIF interface currently available in the
ab/xif-1.0branch.To-do list before review:
