If your software runs on any chip and your chip runs any software, you have a problem, but in embedded cases, you know which chip runs which software, because you designed them together.

This is very true and why I'm not liking that Xilinx is trying to go the other way. It really gets in the way and doesn't work. I know what's connected to what and how, but their system device tree generator doesn't and it yells really loud about that. And I don't even need a device tree, just xparameters.h
