Description

> As discussed in person, and annotated here just for future consideration....a simple register/IP block on the Sonata bus that provided power down/suspend/reset on a physical system (we still have a requirement for a reset block) could also provide shutdown in simulation more elegantly.

Research direction

Start by reviewing issue 368 and its linked discussion, then inspect the Sonata bus and the existing physical reset-block requirements. Define the scope for an IP block that supports power down, suspend, and reset on hardware while also providing simulation shutdown; completion would require agreement on that design and its implementation.
