I assume by 'timebase' you mean the 64-bit tick counter. If so, that is _exactly_ what I am suggesting we do (and what does already happen on ARM). The big change is, the prescaler is common code rather than haven dozens (some of them broken) implementations Regards, Graeme _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
