The SPL can already be compiled for these platforms. What you're doing
is allowing the NAND support to be compiled in the SPL.

[U-Boot] [PATCH 3/8] sunxi: Allow SPL to be compiled for sun8i platforms

[Miquel Raynal]

Add some clocks/PLL definitions and the dependency on MACH_SUN8I in
Kconfig so the SPL could be compiled to boards using A33 SoCs.
