Nevertheless, SPL reads all zeroes from nand. Regarding the sunxi_nand_spl.c module, I can not find any mention if it implies NAND_ECC_HW, NAND_ECC_HW_SYNDROME, or rather some other mode, or if these modes are irrelevant in this case? Can not guess browsing through the code, it looks too different from sunxi_nand.c to compare.
