R-Car H3 with OpenCL

Hi,

I'm trying to include OpenCV 4.x with OpenCL enabled in my Yocto 3.1 Dunfell in the Rcar H3 device. OpenCV 4 is fine and I can build the yocto with that, but OpenCL part is problematic.

There is an opencl layer, but it needs to include some binary files in the layers before starting the build which I couldn't find them anywhere.

There used to be a tarball file here in this dead link :  https://www.renesas.com/us/en/solutions/automotive/rcar-download/rcar-opencl.html but nothing provided as an alternative from Renesas.. nothing that I could find. 

Do you guys have any idea how can I proceed?

If you want to see which binary files exactly, here I list them from this guide:

libOpenCL.so
libPVROCL.so
ocl_unit_test
boclcompiler.so
libglslcompiler.so
libdbm.so
libdlc_REL.so
libufwriter.so


So, any help/hint is appreciated.

p.s: in the elinux the OpenCL help page is T.B.D, but the older version is available and I found that dead link there.
