I still don't see why u-boot would not end up where specified. The fact that there is a "plug-in" (I assume it's what I would call an IPL) does not change the fact that its payload (u-boot) can and will be loaded where specified, i.e. at TEXT_BASE -- and if it is loaded elsewhere, it is at a fixed address, so TEXT_BASE can be adjusted) All IPLs that I know of put their payload where specified. > Thanks for your comments.
