One small request: Can we try to avoid the "NFC" name here? I think it's
too overloaded and people may confuse it with near-field communication,
which I'm sure will be supported in sunxi based devices at some point.

It doesn't hurt to also mention that the function block is called
nfc, but I think references to it are better named "nand", which is
less confusing.
