[meta-xilinx] security patches in the Linux kernel in the meta-xilinx

Hi Philip, Nathan,

meta-enea is available under this URL:

Yes, it would be good  for meta-xilinx users to get security patches that apply to the Xilinx kernel but the questions is  where we should send those patches. 
Maybe we should contact "git at xilinx.com" to upstream security patches in the  in the future.

Is meta-enea public? (I dont't see it in the layer index) It would be nice for users of meta-xilinx to have some knowledge of security patches that apply to the Xilinx kernel.

In the meta-xilinx layer we directly use this kernel, we avoid patching it within meta-xilinx except under very specific circumstances (e.g. backporting bug fixes).
