I think Reinhard is already thinking about a solution.

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.
