Generating DAC bundles

Optionally, you can enable DAC bundle generation for a specific target platform. It will use BundleGen, skopeo and umoci to do this. More info on BundleGen can be found here: https://github.com/rdkcentral/BundleGen . These tools don't need to be installed separately. They are built within the Yocto environment.

You can enable bundle generation by adding BUNDLE_GENERATE = "1" to conf/local.conf. By default it will generate a tarball bundle for RPI3 reference image. The bundles are output in the ./bundles/ directory together with a test script to easily upload and run it on the target.

Other options are these:

• BUNDLE_PLATFORM: use a different target platform. Defaults to "rpi3_reference"
• BUNDLE_OPTIONS: extra commandline options for BundleGen. Defaults to "-m normal"
• BUNDLE_TEMPLATE_PATH: path where to find the template files for your target. You could set it to "${TOPDIR}/templates" and put your templates in there. Example templates: https://github.com/rdkcentral/BundleGen/tree/master/templates
