Our jitterentropy port on ARM depends on the performance counters. To
use them on base-hw/ARM you have to explicitly enable user space access
to the performance counters by setting 'SPECS += perf_counter' in your
<build>/etc/specs.conf file.

The easiest way would be to use the ram_fs component indeed.
