kvx: add support for kvx arch to uClibc-ng
This commit adds support for Kalray VLIW family (kvx)
Kalray kv3 core is embedded in Kalray Coolidge SoC. This core which is the
third of the KV family has the following features:
32/64 bits execution mode
6-issue VLIW architecture
64 x 64bits general purpose registers
SIMD instructions
little-endian
In order to build a usable toolchain, build scripts are provided at the
following address: https://github.com/kalray/build-scripts.
Kalray uses FOSS which is available at https://github.com/kalray
This includes Linux kernel, uClibc-ng, gcc, binutils, etc.
