The only think I don't see (and have been looking for a standalone app that
I am writing, is the difference between load address and entry address.

In the hello_world.c application, it's configured to run at address
0x00040004, but the load address is 0x00040000 - why in this case is there
a 4 byte difference.

=> tftp 40000 /tftpboot/hello_world.bin
...
=> go 40004 This is another test.

I assume that this is a toolchain issue, and may be offtopic for this list.

A slightly different issue - I know that you can load up an elf image as a
standalone app as well, but I don't seem to be able to pass it any command
line args.

=> tftp 1000000 /tftpboot/hello_world
=> bootelf this is another test

fails, becuase U-boot trys to pass "this is another test" to bootelf, and
it doesn't like it.
