The DCD part now matches exactly for the top part (00000000 to
00000020) of it which i guess is the IVT header, which shouldn't be
the same?
The following is xxd where barebox (left side) has been shifted 0x400
to match u-boot part.

So I guess that the DCD table part now should be correct. So the
question is if this is and lowlevel.c/board.c boilerplate issue or
maybe I need something in the Kconfig menu.
