Note that these are two different issues.
Scripting (i. e. the capability to run canned command sequences) has nothing to do with standalone programs like those in the examples/ direcotry.
the hello world program with one of my own programs. How can I compile my own program ? No info is available in the manuals I've read. I've already tried with the Makefile that's included with the examples and set ARCH to ppc and TOPDIR to ../u-boot/ (for config.mk) but that fails.
The simple way: just place your code in the examples/ directory and add a new target to examples/Makefile; alternatively, you can add you code to your board specific directory and adjust the makefile there. See for example boards/trab which includes some extra targets (trab_fkt.srec, trab_fkt.bin) for standalone hardware test routines.
Best regards,
