	  Support for EZchip development platforms,
	  based on ARC700 cores.
	  We handle few flavours:
	    - Hardware Emulator AKA HE which is FPGA based chasis
	    - Simulator based on MetaWare nSIM
	    - NPS400 chip based on ASIC

config EZNPS_MTM_EXT
	bool "ARC-EZchip MTM Extensions"
	select CPUMASK_OFFSTACK
	depends on ARC_PLAT_EZNPS && SMP
	default y
	help
	  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.
