As a firmware debugger, I want vemu to finish its ITM (instrumentation trace) model, so that I can depend on printf trace for production firmware, not just the common path.

Why it matters

printf trace

Summary

SW-driven trace messages

Scope of work

Currently a register-only stub. Replace it with a working model of ITM (instrumentation trace) that actually exhibits the hardware behavior. What it is: SW-driven trace messages. Why it matters: printf trace.

Current state

Status: Stub only (registers, no behavior). Notes / evidence: ROM-table entry only.
