There is no technical reason to add additional 4k space for FDT.
Could it be that this is needed for adjusting the FDT early on ?
It really depends how early. fdt_totalsize is called in reserve_fdt(). It means if this is done before then you are working with already updated size and there is no need to add any space. And switch/copy is done by reloc_fdt from board_f.c.
And in your case it is really question if 4k additional is enough. Because you can have a need to use more then 4k.
