This makes it possible to share the loader relocation code between arches, so that any flavor of loader(8) can be self-relocatable. Then r282731 makes the arm ubldr flavor of loader(8) relocatable. The benefit is that a board-specific setting of UBLDR_LOADADDR is no longer needed at compile time. Unrelated work around the same time (r283035) made loader aware of the fact that arm kernels are relocatable and can be loaded on any 2MB boundary in physical ram. -- Ian
