Added the 'fdtcmd' environment variable as a way to provide 'fdt' commands that the user can supply to manipulate the device tree after ft_board_setup() and before the tree is handled to the kernel.
The idea is that users may want to add or manipulate nodes w/ changing the u-boot binary. The current point in the code we do this we have yet to determine the final size and have yet to do the final fixup of the initrd information.
If its desirable for the 'fdtcmd' support to have the proper initrd information a bit of code reorder will be in order.
The current state of the bootm implementation is bad enough, but adding such a callback opens just another few cans of worms. Sorry, but I do not want to see that in mainline.
I dont see how this is different than the proposal of moving to a script based mechanism for doing a large portion of what bootm does today.
I get not wanting to add the the complexity that is bootm. But I dont think the script mechanism is the right answer either.
