Actually "go" is the native command that is supposed tobe used to
start SA apps.

Frankly, this is crap.  You don;t make use of the image header here,
so you could as well save all the efforts.  Just store "hello_world"
(the ELF file) in your file system, then load that dierectly, and
start it.  There is no sense in using mkimage as done above.

And how would you pass additional arguments to the SA app?

Use "go", this was made for the purpose at hand!
