[yocto] Using SDK/ESDK to build images

[Kristupas Savickas]

Hi,

we're looking into providing our customers with SDK/ESDK packages to 
develop custom solutions on our boards. We don't want to provide the 
whole project itself as it would leak our intellectual property, so 
precompiled packages are a must. Looking around, it seems like both SDK 
and ESDK are suited to build single packages, rather than complete 
images. Am I correct about this? Is there some kind of method to allow 
images be built using SDK packages?
