What is the endian of your ARM9 testbed?

I've tested the hello_world standalone image with and without your patch on 
a T5040 (BE). Behaviour of "bootm" does not change. So I am not sure what 
problem this patch fixes on PowerPC, if any. The patch might be applicable 
only to certain archs so you should test it on other archs as well 
(otherwise this patch might break them).


As a reference, the standalone image was created using the commandline:
../../tools/mkimage -A powerpc -O u-boot -T standalone -C none -a 0x10040000 
-e 0x10040000 -n test -d hello_world.bin hello_world.img

(Yes, I modified CONFIG_STANDALONE_LOAD_ADDR for this test.)
(Yes, hello_world was modified to not return for this test.)


And executed, on the board:
tftp 100000 hello_world.img
bootm 0x100000

Also, your patch does not apply on master.

All the best,
