Hi,

And while at it, why not finally add the DT register definitions for Allwinner A20 NFC. I'm certainly not the author of these, and they have been
[...]
nand_pins_a: nand_base0@0 {allwinner,pins = "PC0", "PC1", "PC2","PC5", "PC8", "PC9", "PC10","PC11", "PC12", "PC13", "PC14","PC15", "PC16";allwinner,function = "nand0";allwinner,drive =<0>;allwinner,pull =<0>;allwinner,{pins,function,drive,pull} syntax has been deprecated in favor or general pinctrl syntax.
You can check how sun5i.dtsi defines these blocks.
Well, I could certainly do such editing, but I'm not sure if something related in the tree will also need to be updated accordingly, therefore I'd prefer to refrain. I'm rather a u-boot user than a u-boot developer, I can do some simple searching and testing, but probably not refactoring. Thing is, however, the original Allwinner's implementation of nand boot procedure for A20 appeared to be so messy and fragile and inconvenient that using u-boot's mainline approach is basically the only reasonable choice for this device. (And btw great thanks to all developers who implemented it!)
