While I'm in favor of having some way for SPL to pass data to U-Boot, I don't think this patch achieves this as long as we don't have a common mechanism that makes use of this struct. At the very least I would've expected to see a #define that is shared by SPL and U-Boot that defines the address for this struct (if we were to use the ventana implementation).
