you mean using irq_set_chained_handler() ? 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.
