If yes, this IMHO doesn't look usefull because it's used for adding a secondary interrupt controller. But what I need is telling bridge ASIC to direct the xtalk IRQ packet to a specific HUB/HEART/BEDROCK from the HUB/HEART/BEDROCK specific code. And want to avoid dragging in bridge details to that specific code. But I'm open reusing whatever fits the bill here.
