I'm not really sure if this is what we need. You suggest to use different MACHINEs of one SOC_FAMILY, Right?

But if I bitbake the root filesystem for each MACHINE an *own* image is created. And not *one* usable for all of them.

What we wish is one image containing one kernel and device tree files for each product.

In addition a u-boot image for each product so that we can use a boot setup running different u-boot images starting the same kernel and root filesystem with different parameters (e.g. for the device trees).
