Add a new "fdt_high" enviroment variable. This can be used to control (or
prevent) the
relocation of the flattened device tree on boot. It can be used to prevent
relocation
of the fdt into highmem. The variable behaves similarly

Well, that does sound strange. I'd think

Our boot script loads the kernel 2MB into physical RAM. It loads the
initrd and fdt from the same NAND flash file system into RAM below that.
When we boot without specifying an FDT, u-boot

If one excludes HIGHMEM from the area u-
