At some point the distro has to install a dtb into some cannonical
place so the bootloader can find it..
Are you thinking that distros will have to ship a /boot/dtbs/*.dtb
with every dtb from the kernel build?
What happens when you install two different versions of the kernel?
What about boot schemes that can load a kernel version dependent dtb?
I've said this before - I really think the kernel community will do
itself a big favor if it encourages boot schemes that can handle a
kernel version dependent dtb, rather that design schemes that
absolutely can't allow for that.
