I think if the specific ARM platform you are working supports a oneshot 
clock_device, you would get the high res timer support.

You can check for clock_devices defined in your platform having feature 
- CLOCK_EVT_FEAT_ONESHOT.

rdtsc is x86 specific... Sorry.

But there are other options.

Compares rdtsc with hpet:

Other reference about timers:

I'm not sure if HPET works on ARM.
