Completely nothing :)
The upstream SPI NAND framework is available in 4.19. I do have a
backport of it to 4.14 but that changed so many things that it doesn't
As for raw nand driver for AR9344/QCA9558, the ar934x-nfc driver isn't
ported to ath79 yet.

No due to lack of a SPI NAND driver.

I agree. I think this subtarget should be disabled.
