Re-map NAND&I2C boot-device to the "normal" NAND boot-device. Otherwise the SPL boot IF can't handle this device correctly. Somehow booting with Hynix 4GBit NAND H27U4G8 on Siemens Draco leads to this boot-device passed to SPL from the BootROM. With this change, Draco boots just fine into main U-Boot.
