[PATCH 00/31] Andes(nds32) Linux Kernel Port

[Greentime Hu]

This patchset adds core architecture support to Linux for Andestech's
N13, N15, D15, N10, D10 processor cores.

Based on the 16/32-bit AndeStar RISC-like architecture, we designed the
configurable AndesCore series of embedded processor families. AndesCores
range from highly performance-efficient small-footprint cores for
microcontrollers and deeply-embedded applications to 1GHz+ cores running
Linux, covering general-purpose N-series cores for a wide range of computing
need, DSP-capable D-series cores for digital signal control,
instruction-extensible E-series cores for application-specific acceleration,
and secure S-series cores for best protection of the most valuable.

The patches are based on v4.14-rc8, and can also be found in the
following git tree:
  https://github.com/andestech/linux.git nds32-4.14-rc8

The build script and toolchain repositories are able to be found here:
  https://github.com/andestech/build_script.git

Freely available instruction set and architecture overview documents can
be found on the following page:

Vincent Ren-Wei Chen and I will maintain this port. Thanks to everyone who
helped us and contributed to it. :) Any feedback is welcome.
