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.
