Currently i need these labels in uboot to add additional properties (e.g. hwver to cpu-nodes) and linking the existing nodes (clocks to eth node) to some added in uboot overlay.
Currently we face some hen-egg issue as support is in mainline uboot and we forced to move to of_upstream to add pcie support and maybe more,but in mainline linux we miss nearly all nodes we have in our private repos...but i'm busy in getting of_upstream in uboot working basicly.
