Support for ARC770 core introduced with Rel 4.10 (Summer 2011)
This core has a bunch of cool new features:
-MMU-v3: Variable Page Sz (4k, 8k, 16k), bigger J-TLB (128x4)
- Shared Address Spaces (for sharing TLB entries in MMU)
+ Shared Address Spaces (for sharing TLB entries in MMU)

at designated entry point. For other case, all jump to common
entry point and spin wait for Master's signal.

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.
