The memory node gets automatically generated by U-Boot in arch_fixup_fdt(), before passing control to the kernel using U-Boots representation of the dram banks. However the upstream kernel uses the memory node to carve-out regions of RAM for various purposes. To make this work without changing arch_fixup_fdt() which will effect many platforms we replicate the upstream memory node layout using the dram banks.
