Watchdog detection after watchdog reset

[volker]

Hi,
I have non Linux question about the A33. Maybe someone could help me:
I working on an A33 and would like to detect if the watchdog has rest my board.
Is there a register, that saves the state, if the watchdog has reset the chip?

The use case is: Linux set the watchdog. After a reset, I would check in U-Boot, if the watchdog has triggered the reset, I would like to boot a rescue system.

Thanks,
Volker
