IMHO, haveged is not well supported on ARM (yet).  Yes, we can build
and run haveged with --enable-clock_gettime option.  But I think that
this should be improved to use high resolution timer, if people really
want to use haveged on ARM.  That's because high resolution timer is
crucial part of haveged.

It seems for me that support of (userspace) high resolution timer on
ARM is not that good situation, though.  I found following two pages
about userspace high resolution timer on ARM.
