I am saving my environment to flash and relocating it from flash to ram when uboot starts. After I burn the flash, and run uboot, I noticed that the environment that was relocated had garbage data in it. I need to figure out if my build is incorrect,

Please restrict your line length to some 70 characters or so.

Your build is obviously incorrect, as it doesn't run correctly ;-)

and if not, how can I define a buffer in uboot that is located at a fixed address, and is intialized to all zeros

You can create a data aobject of sufficient size and edit the linker sript to place it where you like, but I cannot see a valid reason why you would want to do that. If you need zeroed RAM, just use data in BSS.
