I don't think that's justified, only a few boards have SPI flash,
really, also it's a new driver that nobody desperately needed so far.

What about:
	default y if ARCH_SUNXI && SPI

That would mean to just define CONFIG_SPI=y in a defconfig to enable SPI
(flash) support for a board.
Similar we should add
	select DM_SPI if SPI
	select DM_SPI_FLASH if SPI
to the ARCH_SUNXI stanza in arch/arm/Kconfig

Cheers,
Andre.
