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:

Hopefully this can get the ball rolling on how to properly implement SPI NAND support in mainline U-Boot.
