I have to admit, that without looking too deep into the fdt code, I don't see 
a way to set the force flag upon Linux booting. Here the code from 
common/cmd_bootm.c:

        /*
         * Add the chosen node if it doesn't exist, add the env and bd_t
         * if the user wants it (the logic is in the subroutines).
         */
        if (of_flat_tree) {
                if (fdt_chosen(of_flat_tree, initrd_start, initrd_end, 0) < 0)

As you can see, the force flag is always set to 0. So how should "force" the 
chosen node manipulation? Perhaps I'm missing something here.

Best regards,
Stefan
