Global Clocks Driving Register Resets

DS180 indicates for Spartan-7 and Artix-7 (and other) devices, that the global clocks can route to and directly drive asynchronous control signals, such as the reset inputs on logic and (presumably also) I/O registers.

Does the same hold true for Spartan-6 devices, and for Spartan-3A devices?  Regarding the latter, note that UG331 indicates on p.46 that "clock routing resources...can only drive clock inputs".
