You sure?  When I read to commit history correctly SPL NAND support for
sunxi has been introduced 2015-08:

        2015-08-08      Piotr Zierhoffer
            sunxi: nand: Add basic sunxi NAND driver for SPL with... 

I'm booting the C.H.I.P. with mainline SPL 2015.10 and let it load
U-Boot 2016.09-rc1:

        U-Boot SPL 2015.10 (Dec 22 2015 - 20:46:00)
        DRAM: 512 MiB
        CPU: 1008000000Hz, AXI/AHB/APB: 3/2/2


        U-Boot 2016.09-rc1 (Jul 31 2016 - 16:37:00 +0200) Allwinner Technology

        CPU:   Allwinner A13 (SUN5I)
        Model: NextThing C.H.I.P.
        I2C:   ready
        DRAM:  512 MiB
        NAND:  8192 MiB
        Using default environment

My question still is if somebody knows why SPL 2016.09-rc1 fails?  Maybe
I should revert the changes step by step and see which one broke it.
