   6 # Qualcomm SDK (QSDK) sysupgrade compatible images for IPQ40xx, IPQ806x
   7 # and IPQ807x use FIT format together with 'dumpimage' tool from U-Boot
   8 # for verifying and extracting them. Based on 'images' sections names,
   9 # corresponding mtd partitions are flashed.
  10 # This is a simple script for generating FIT images tree source files,
  11 # compatible with the QSDK sysupgrade format. Resulting images can be
  12 # used for initial (factory -> OpenWrt) installation and would work
  13 # both in CLI and GUI. The script is also universal in a way it allows
  14 # to include as many sections as needed.
