If that's sufficient, why would you need the -mrelocatable option on PowerPC? -fPIC makes the compiler generate position-independent code, which is necessary but not sufficient in order to get a fully relocatable binary. The second part of the puzzle is dynamic relocations. Shared libraries have them, and apparently, PowerPC binaries have them if you link with -mrelocatable. Currently u-boot is compiled with -fPIC, so the result is almost fully relocatable. We work around the lack of dynamic relocations by manually fixing up a handful of pointers at runtime.
