That's the one. You cannot just put a NAND flash chip at the CPU's startup
vector and let it boot from it. You need _something_ for the CPU to start
with, be that SROM, a tiny NOR flash or ROM, or something else. All you
need is a few bytes to set up your DRAM and start pulling the real
bootloader off the NAND flash.
