Please do not top-post! (put your own comments _after_ the quoted
portion of the original mail you are responding to just like everyone
else on this mailing list).

Your SDRAM size is 2GiB. That means U-Boot will relocate the FDT
outside reach for the kernel. Try setting 'fdt_high=0xffffffff' (or
${fdt_addr}), to prevent U-Boot from relocating the FDT.
