[U-Boot] [PATCH] display the entry point when compiling a stand-alone program

[Timur Tabi]

Contrary to popular belief, the entry point for a stand-alone program is not
consistent.  The only way to know for sure is to use the nm program and
search for the entry point function.  So we update the Makefile build rule
to display this entry point after the ELF image is created.

I was thinking along the same lines but decided that this is not the
correct solution but only sweetening the fall ;)

We should concentrate on creating a correct linker script so that the
entry point ends up where we want it to be, namely at
STANDALONE_LOAD_ADDR.

Can you have a look at this and maybe solve the problem for good then?

Thanks!
  Detlev

I have no idea how to do that.  I don't know diddly about linker scripts.
