The partition scheme is defined using the config file config/platform-tq-mbls102xa/config/images/uboot-hd.config. 

To create the image the genimage host tool is used. This tool is automatically selected and built. You can find the build directory under <BSPROOT>/platform-MBLS102x/build-host/genimage. See the README file for how to use this tool.
