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