GL-AR300M - Compile images for NAND?

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)

Can someone point me in the right direction as to how do I either compile or get images to install on the NAND?

NAND support is available only in snapshots.
