No, it's vice versa. U-Boot has always been just implementing what
the kernel does. There are many other boot loaders around that all
have to adhere to the interface(s) imposed on them by the kernel.

Well, actually nobody has problems: the ARM and MIPS folks have
working solutions, too. The next architecture will implement yet
another way of passing information to the kernel, implement it and
state that they will not accept any other solution, and so on.
