U-Boot expects the FDT to be located right after the _end linker symbol (see fdtdec.c: board_fdt_blob_setup())
The "basic" LOAD_FIT path is aware of this limitation, and relocates the FDT at the expected location. Guessing the expected location probably only works reliably on 32-bit arm, and it feels like a hack. One proposal would be to pass the FDT address to u-boot (e.g. using 'r2' on arm platforms).
The variable is named "fdt_hack" to remind future contributors that, "hey! we should fix the underlying problem". However, that is beyond the scope of this patch.

Applied to u-boot/master, thanks!
