DTS file of a chosen platform.
Clocksource may be depend on some clk from DTS as the
real source of this clock.

In SMP setup, master loops for each_present_cpu calling cpu_up().
For ARC it returns as soon as new cpu's status becomes online,
However secondary may still do HW initializing,
machine or platform hook level.
So turn secondary online only after all HW setup is done.

NPS device got 256 cores and each got 16 HW threads (SMT).
We use EZchip dedicated ISA to trigger HW scheduler of the
core that current HW thread belongs to.
This scheduling makes sure that data beyond barrier is available
to all HW threads in core and by that to all in device (4

NPS use special mapping right below TASK_SIZE.
Hence we need to lower STACK_TOP so that user stack won't
overlap NPS special mapping.

With generic "identity" num of CPUs is limited to 256 (8 bit).
We use our alternative AUX register GLOBAL_ID (12 bit).
Now we can support up to 4096 CPUs.

Since the CTOP is SMT hardware multi-threaded, we need to hint
the HW that now will be a very good time to do a hardware
thread context switching. This is done by issuing the schd.rw
instruction (binary coded here so as to not require specific
revision of GCC to build the kernel)

The default 256 bytes sometimes is just not enough.
We usually provide earlycon=... and console=... and ip=...
All this and more may need more room.

This will better reflect its description i.e. "any needed setup..."
and not just do an "IPI request".

We need our own implementaions since we lack LLSC support.
Our extended ISA provided with optimized solution for all 32bit
