AR300M-EXT custom NAND Images

I am able to compile OpenWrt 19.07.4, r11208-ce6496d796 successfully using the openwrt git source but the images only support the generation of .bin images for NOR (Atheros AR7XXX/AR9XXX) (Generic) (GL.iNet GL-AR300M)

How do I get images to install on the NAND?

You can find it in the snapshot of ATH79

How do I get MY images to install on NAND? I’m not looking for the pre-compiled images. The gl-inet git source is broken for the AR300M-NAND and is impossible to build/compile. I had an older source from gl-inet that was working but after I updating it broke, and now none of the git images seem to work anymore as they are full of build/compile errors. The generic versions build/compile but not the AR300M-NAND. I’ve tried clean new downloads/images of multiple versions and none of the gl-inet sources work anymore.
