Why don't you help yourself? Configure and compile U-Boot for your
platform, then do a "touch examples/standalone/hello_world.c", do a
"make" again and study what commands are being generated. This is what
you will need to rebuild in your own makefile.
If you do this however, you may notice that it is not very trivial to
separate your application from U-Boot, as you will need the libstubs.a
and the header files. Maybe you would be better off to use what is
available and simply add another target to the makefile in the
standalone directory.
Cheers

Once the implementation is up and running, it is still a trick to keep it
running. In a normal, closed implementation, this is not a problem; in a
system with metaobject protocols [..] there is the potential for spectacular
failure modes if certain situations are not properly anticipated.
