 Is there a way to enable high resolution timers on AT91SAM926x? The
best resolution I can get (kernel with at91 patch from is around 1ms. Is there any other way to get timers with
better resolution?

prerequisites for CONFIG_HIGH_RES) I'm unable to compile at91 part of

Is there any "unofficial" patch? I saw that in 2.6.24 high res is
supported for ARM, but AT91 still lacks support.
