Hi,
The FUIDR is a 64-bit value set (and write protected) with a software readable value. You can use images that
can only pass secure boot on a specific chip.
This FUIDR value is replaced with a process in the LS1028A, such thing does not occur in almost all LayerScape processors.
The reason that the register is replaced with the process is to ensure the protection intended even in the documentation itself.
Thank you for your patience, regards
