In BROM/ffff4000.s, nand_set_boot_random_seed loads 0x4a800008 into NAND controller register 0x34. The high word is the random seed, but the low bits (0x08) correspond to NFC_ECC_PIPELINE, not NFC_RANDOM_EN (0x100). At least that's what the flag is called in u-boot and linux sources from Allwinner.
