From: Simon Glass <sjg@chromium.org> It is sometimes useful to create a different main program for U-Boot, or even to use some parts of U-Boot in an entirely different project. Add a new option to allow building a .so from parts of U-Boot. For now this does nothing. Enable it by default for sandbox, excluding the tools-only build, where it has no meaning.
