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.
