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. For example, in case of NOR-only boards, below mapping is used (section name -> mtd name): hlos* -> 0:HLOS rootfs* -> rootfs And for boards with NAND (kernel inside UBI): ubi* -> rootfs Above mappings come from unmodified QSDK sources and might be wrong for boards running custom or modified QSDK-based firmware. Some of vendors adjust them to meet their modified mtd layout or features like recovery or dual-image support. This adds simple script 'mkits-qsdk-ipq-image.sh' (based on 'mkits.sh') 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 universal in a way it allows to include as many sections as needed. To make use of it, two generic/basic build recipes for NOR and NAND based boards are also included in 'image-commands.mk': Build/qsdk-ipq-factory-nand Build/qsdk-ipq-factory-nor Example usage for board with UBI in NAND: IMAGE/nand-factory.bin := append-ubi | qsdk-ipq-factory-nand Signed-off-by: Piotr Dymacz <pepe2k@gmail.com>
