16	Add an absolute time reference in hexo	Nicolas Pouillon	becoulet	"We need an abstracted method to retrieve the architecture's frequency. This can be useful to:
 * know about the real time elapsed
 * implement real data rates (some devices use a subdivision of the main clock for generating baudrates, that means we have to know the main clock freq)

This could be declared in hexo, implemented in arch. Depending on the arch, it could be:
 * a calibrating loop on ibmpc
 * in the fdt for soclib
 * depdendant on the arch for simple

Some problems are non-trivial to solve but may be addressed later:
 * CPU frequency scaling
 * GALS
