The firmware is not different. However the signature on these images is 
different with each image having a different SWID. This is a limitation 
coming from TZ at this point. There is an FR93715 on TZ, to be able to 
use single signature for authentication. This is TBD on future targets 
from TZ i believe. Till that time for our QLI meta to load this image on 
available NSPs different copies needs to be there.
