We are working with the iMX28 with Yocto (morty) building the 4.1 kernel and using the linux.sb & linux.sdcard output to burn a µSD image. We use rpm packages to do over-the-air updates to are target device but the bootstream is not packaged by morty. I can arrange for the bootstream to be left in "tmp/deploy/images/<machine>" but I don't know how to get the packaging system to make a package of it, preferably named with the same version number as the kernel and it's modules.
Has anyone done this?
