+ Support for EZchip development platforms,

+ We handle few flavours:
+ - Hardware Emulator AKA HE which is FPGA based chasis
+ - Simulator based on MetaWare nSIM
+ - NPS400 chip based on ASIC

+ Here we add new hierarchy for CPUs topology.
+ We got:
+ Core
+ Thread
+ At the new thread level each CPU represent one HW thread.
+ At highest hierarchy each core contain 16 threads,
+ any of them seem like CPU from Linux point of view.
+ All threads within same core share the execution unit of the
+ core and HW scheduler round robin between them.
