Update Bootloader In An OTA Using The updater_script

Hi,

 

Maybe some one can Help me with this. I am trying to update the bootloader in an OTA (update.zip). I added the "u-boot-no-padding.bin" to the update zip, and then modified the updater_script. Is there anyone who might be able to tell if this updater_script is correct? I added the section at the end about u-boot.
