Yes, it is not the proper solution but at that time binary was already broken and I did not find at that time better fix for it to have again working u-boot build. > So I would be against what you did , to align to 4 bytes.

And allows to put DTB at any position or alignment. Then alignment could be changed also for mpc85xx to 8 or 128 bytes...
