Plain U-Boot doesn't use any interrupts, although there are files like cpu///interrupts.c which contain some timer handling functions. But nevertheless you can implement your own interrupt handling while being quite sure that no standard drivers or functions from U-Boot will cause conflicts. If you want to push such an interrupt based functionality to the mainstream U-Boot, this will probably not be acceptable, unless you have extraordinary good arguments why interrupts are required.
