Methods to Reset Persistent Partition
Use bootburn with additional argument --init_persistent_partitions to
         reset the persistent partition. 
Alternatively, if you are using create_bsp_images.py and
            flash_bsp_images.py, add --init_persistent_partitions
         to only create_bsp_images.py and flash_bsp_images.py
         resets the persistent partition.
To reset the partition there are two (2) different workflows:
   - Using bootburn.py to flash target: Please add --init_persistent_partitions command-line argument to bootburn.
- Using create_bsp_images.py + flash_bsp_images.py to flash target: Please add --init_persistent_partitions to create_bsp_images.py. (No --init_persistent_partitions command-line argument required for flash_bsp_images.)
