This works.
I included this in a file "openwrt/target/linux/generic/pending-5.15/489-mtd-spi-nor-add-fudan-fm25qxxx.patch" and recompiled.
The device now boots and works. Thank you for the assistance. I actually used the version a little further down in that thread Hasivo switches - #41 by bevanweiss
Not sure that the name fits conventions though. 4xx is for mtd related patches but I don't know how the sequencing works. Going to learn more now.
Thank you for the assistance!
