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: http://www.andestech.com/product.php?cls=9 Vincent Ren-Wei Chen and I will maintain this port. Thanks to everyone who helped us and contributed to it. :) Any feedback is welcome.
