This series is my current working and tested setup for booting from SPI NAND chips on the Allwinner T113.
I have included the following patches from others. I may have modified them to work with the latest mainline: https://lore.kernel.org/all/20221014030520.3067228-1-...@icenowy.me/ https://lore.kernel.org/all/20231111133432.755363-2-biguncle...@gmail.com/ Hopefully this can get the ball rolling on how to properly implement SPI NAND support in mainline U-Boot.
