Insert one step here:

then run dd if=coreboot.rom bs=1 \
 skip=$[sizeof(coreboot.rom) - 0x10000] count=64k | hexdump
# and verify that the complete range is filled with ff bytes before
# proceeding further. if this is not the case, the coreboot image
# needs to be recreated with the second-to-last 64kbyte block unused

That should of course read:

then run dd if=top64k.bin of=coreboot.rom bs=1 \
 seek=$[sizeof(coreboot.rom) - 0x20000] count=64k conv=notrunc
