Adding wifi nfs boot to initramfs, under armbian and uboot

I'm trying to setup my an initramfs image to nfs boot from a WPA wifi access point. My image is working with armbian and uboot. so far I have NFS booting over ethernet just fine. But no real path to follow on the idea of getting all the right software, drivers, modules and scripts onto the initramfs image or even which are the right software,drivers,modules, scripts. For hardware I have 35 OrangePi Zero - manufacture link and wiki link The idea is to get them all up and booted from nfs using wifi and one sd card.
