On the other hand , what you are saying Pali, that objcopy trims trailing zeros, and your platform is broken, hence you are aligning to 4 bytes, I do not think that alignment to 4 bytes is the solution.
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. If the DTB is appended at the wrong position (somehow this is happening in my case as well), we should have U-boot (and your platform) look up the DTB at the right position , where it's supposed to be placed. And not move the DTB to a 4 byte alignment just because Uboot searches the DTB there. In the future if the DTC requires all DTBs to be aligned to 8 bytes as a hard rule, your solution is again not right. We would have to have the DTB aligned to 8 and the code to lookup the DTB in the right position.
So looking up the _end and placing the DTB directly there might be a better way to solve all the problems we are facing (as you actually suggested )
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...
