Hi David,
It looks like the entry point is 0x40000. Why does the tutorial state that the example needs to be run from a 4 byte offset? In this case this will result in a failure to create a stack frame for hello_world.
For PowerPC the entry point used to be non-deterministic, but was generally 0x40004 which is where the wiki value came from. The following 2 patches made the entry point consistently 0x40000:
http://git.denx.de/cgi-bin/gitweb.cgi?p=u-boot.git;a=commit;h=620bbba524fbaa...
http://git.denx.de/cgi-bin/gitweb.cgi?p=u-boot.git;a=commit;h=c91d456c055237...
I updated the wiki to match the newer 0x40000 address, which is valid for PowerPC boards with a comment to check out CONFIG_STANDALONE_LOAD_ADDR for other architectures.
