The only way to find out for sure is to test it. You'll probably need to enable cuImage support in the kernel, at the very least. No one keeps track of whether newer kernels work with older U-Boots, so there's no way to know in advance whether a specific kernel and a specific device tree and a specific (older) U-Boot will work together.
Thanks for the comments.
However my concern is specific to the powerpc arch. If I understand correctly, the powerpc arch expects a bootloader provide a DTS file. I'm not sure how the current U-Boot transfers such info to the kernerl. People here can shed some light on this? I'm certain the old U-Boot (e.g. 1.1.2) doesn't have this kind of capability. The bd_info is still one of data transferred to the kernel, right? How does bd_info work with the DTS info?
Thanks, -Shawn.
