Problem building image "dev + stretch" for banana pi m1+

[hanni76]

Hello, guys,

 

I need your help with building an image with kernel 4.15 ("dev") for bananapi m1+ (can't use "next" because I need the new display engine).  First of all, I need to transfer patches from 4.14 so that I can create my own overlays. Can you tell me which patches I need to look at , besides "add-overlay-compilation-support.patch" ? 

Thank you
