Hello,

I am currently attempting to utilize Verified Boot to verify FIT images on my 
T104x-based device. I am building U-Boot with the standard options for Verified 
Boot (CONFIG_FIT, CONFIG_FIT_SIGNATURE, CONFIG_RSA, CONFIG_OF_CONTROL and 
CONFIG_OF_SEPARATE).


When building U-Boot I need to supply a DTB image at build time. However, the 
device I am targetting may have a number of different configurations. This has 
been manged previously by using a single version of U-Boot and loading 
different FIT images containing different DTBs based on how the device will be 
used.


Does the DTB supplied to U-Boot at build time have to be "fully-featured"? Can 
it be a dummy DTB containing minimal nodes just for the purpose of storing the 
key contents for Verified Boot?


Kind regards,

BDG
