Xilinx has the Deep Neural Network Development Kit (DNNDK) that they just released the source code for in the last month or so. They have the code written nicely in the form of yocto recipes but it doesn't appear to be an actual layer: https://github.com/Xilinx/Edge-AI-Platform-Tutorials/tree/master/docs/DPU-Integration/reference-files/files . Is there a possibility of creating a layer for it? Or should I look into other options, like adding it as a submodule to my custom layer meta-l1calo: https://github.com/kratsg/meta-l1calo? 

Or if anyone has additional options, suggestions are appreciated! 

Thanks for the help!
