Urgh... no!!! U-Boot is definitely *not* suitable for any kind of real-time tasks. By design it implements strict single-tasking with usally polling hardware access only. No multi-tasking, no interrupts, no locking, no timers, nothing... > You can't get much more arms length than that except perhaps requiring U-Boot > to use an interrupt.

You could not implement any of this without heavily relyin on and deriving from internal interfaces of U-Boot which are not exported for non-GPL use.
