Completely unrelated, but do you have any pointer for how to do this?
Hot plugging a 'dtb fragment' into the kernel would be really handy..

I'm thinking something like adding a tree below a PCI controller
describing a PCI device and sub nodes, similar to what Thierry was
doing for his Avionics. How would interrupt maps and phandles be
managed across the main dtb and the 'hot plugged' dtb?
