Merge tag 'arc-4.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vgupta/arc
Pull ARC architecture updates from Vineet Gupta:
- support for HS38 cores based on ARCv2 ISA
ARCv2 is the next generation ISA from Synopsys and basis for the
HS3{4,6,8} families of processors which retain the traditional ARC mantra of
low power and configurability and are now more performant and feature rich.
HS38x is a 10 stage pipeline core which supports MMU (with huge pages) and
SMP (upto 4 cores) among other features.

- support for ARC SDP (Software Development platform): Main Board + CPU Cards
= AXS101: CPU Card with ARC700 in silicon @ 700 MHz
= AXS103: CPU Card with HS38x in FPGA
- refactoring of ARCompact port to accomodate new ARCv2 ISA
- misc updates/cleanups
