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.

Yes, for me it looks like a better solution which fixes both problems.
And allows to put DTB at any position or alignment. Then alignment
could be changed also for mpc85xx to 8 or 128 bytes...
