A short look to the arm/cpu/**/timer.c showed that most of them use a 16 bit timer to provide an 32 bit timer value. For that class of timer implementation it would be suffucient to have a 'uint32_t last_timer_val' and an 'uint32_t timestamp' in GD. regards Andreas Bießmann _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
