I've never got "bootm" to run any of the standalone applications in the 
example directory but through trial and error (maybe luck) "bootelf" works 
for me. I've tested that this works with old 2010.XX and latest 2014.XX 
releases. Note I use PowerPC, but worth I try in your case I guess.


This is how I build the hello_world binary:

tools/mkimage -A powerpc -T standalone -C none -a 0x200000 -e 0x200000 -n 
hello_world -d examples/standalone/hello_world hello_world.img

And these are these serries of commands that loads and executes the binary:

usb start
fatload usb 0 80000 hello_world.img
bootelf 80040

Good luck!
