device-tree-compiler is actually needed for all kernels on embedded. Embedded 
devices don't have a BIOS and so you have to have some kind of hardware 
description in order to be able to even boot. The Linux kernel bundles a 
device-tree-compiler, that's why it didn't pop up sooner.

I'm fine with putting it into the u-boot module. Just know that u-boot is just 
the earliest one that needs it (because it patches device-tree files in order 
to pass information about the boot process to the kernel). Next the Linux 
kernel needs it and next all expansion board drivers need it, too. (all of 
those only while compiling)

It's a compiler, so you don't need it at runtime.
