vFlashPack: Simple Transportation of Flash Config

Complete configuration as one single file – containing only relevant data

Minimal but sufficient items in package (incl. flashware: ODX-F, bin, …)

Simply pass packages to others (e.g. from development to production)

Automated vFlash Pack Generation

… as part of build process, e.g. for production

… as extension to generate packages for VN8810
