I understand the advantages of being able to compile multiplatform
kernels - But for the typical embedded device, having the device tree
together with the kernel makes stuff a lot simpler when upgrading
because of the version depencies of the dts.

That's also why I submitted the (nacked) multifile uimage support some
time ago:

The fitimage stuff is the logical continuation of that.
