In this case, I'd not go with OpenSoCDebug for now, but use the or1k 
debug infrastructure with adv_debug_sys & Co. directly. It should be 
easy to revisit this decisions once you have a need for more 
sophisticated debug/trace infrastructure (and by then OSD should also 
have run-control debug working out of the box).
