Banana PI m4 with yocto

Hey, I have BPI-M4 and i would like to work with it using yocto. I saw that there is meta-sunxi layer present but can i use the same layer for m4 too? How can i setup the yocto project for M4? is there any tutorial present? Thanks a lot!

Is for Allwinner hardware. M4 is something completely different.

Thanks! Is there any easy way to make it working for M4?
