Well, it is not clear to me why you want to run u-boot as single
application, instead of replacing the version you have now on target.
And why are you loading u-boot at 0x22000000, because if I see in the
include/configs/at91sam9260ek.h CONFIG_SYS_TEXT_BASE is set to 0x21f00000...

Apart of that, you should also check the bootstrap code (not part of
u-boot), and maybe you have to fix it if the addresses do not correspond
or a smaller image from NAND flash as u-boot is copied.

Best regards,
