[PATCH RFC 00/15] Support SPI NAND booting on the T113

[John Watts]

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-uwu@icenowy.me/
https://lore.kernel.org/all/20231111133432.755363-2-bigunclemax@gmail.com/

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