Hello,
After looking at code, searching the mailing list archive, and reviewing the git commit log, I now understand that for ARM relocation is performed unless U-Boot is already running at its final destination as computed within board_init_f. Since this computation attempts to back off from the end of RAM the resulting address varies when U-Boot changes size. On my board I have an earlier bootloader that initializes RAM. Presently, it copies U-Boot near the start of RAM and lets U-Boot relocate itself to the end. This is inefficient and I would like to eliminate the extra copy. I suspect that my situation is not unique and would be grateful to anyone willing to share their thoughts or experiences on how best to deal with this.
Thanks, Tim Kryger
