The only difference you should notice is that devices load in a different order at boot time. Specifically, you'll see all the busses listed first, then interrupt controllers, then l2cache, then clocks and timers, then all the usual stuff after that. There's no immediate benefit or speedup or anything, this is to help pave the way for using fdt data that comes with a board or system instead of needing our special freebsd dtb files. Right now we count on devices loading in the order we list them in our dts source. This is a new way of loading things that should ensure critical devices are loaded first, even when we can't control the order of things in the fdt data. I've tested this on wandboard only so far. -- Ian
