7 bool "\"EZchip\" ARC dev platform"
11 select EZCHIP_NPS_MANAGEMENT_ENET if ETHERNET
13 Support for EZchip development platforms,
14 based on ARC700 cores.
15 We handle few flavours:
16 - Hardware Emulator AKA HE which is FPGA based chasis
17 - Simulator based on MetaWare nSIM
18 - NPS400 chip based on ASIC
21 bool "ARC-EZchip MTM Extensions"
22 select CPUMASK_OFFSTACK
23 depends on ARC_PLAT_EZNPS && SMP
26 Here we add new hierarchy for CPUs topology.
30 At the new thread level each CPU represent one HW thread.
31 At highest hierarchy each core contain 16 threads,
32 any of them seem like CPU from Linux point of view.
33 All threads within same core share the execution unit of the
34 core and HW scheduler round robin between them.
