Initial Commit: Based on TI OpenCL v0.8, originally based on clover.shamrock_v0.8
This is a continuation of the clover OpenCL project:
http://people.freedesktop.org/~steckdenis/clover
based on the contributions from Texas Instruments for Keystone II DSP device:
git.ti.com/opencl
and adding contributions from Linaro for ARM CPU-only support.
See README.txt for more info, and build instructions.
