Laurent, maybe you could finally send a pull request for that patch here: https://lists.gnu.org/archive/html/qemu-devel/2016-05/msg00805.html ? Meanwhile, Peter, could you please take this patch here from Greg directly? Or should it go via qemu-trivial instead?

Well, this patch was waiting I resend my 680x0 support series, and I didn't have the time to rework it until now... but if you want to merge it as is, don't hesitate. Thanks, Laurent

The shipping default setting for the Freescale M5208EVB board is to run the CPU at 166.67MHz. The current qemu emulation code for this board is defaulting to 66MHz. This results in time appearing to run way to slowly. So a "sleep 5" in a standard ColdFire Linux build takes almost 15 seconds in real time to actually complete. Change the hard coded default to match the default hardware setting.
