AFAIK, you cant, but you can override the internal boot rom by
setting BSM high during reset. THere should be at resistor R159 to
change the bahaviour.

Please note that the AT91RM9200-DK port is not a full port and depends
on Atmels loader.bin is placed first in the flash. The u-boot AT91RM9200-DK
port do no initialize cpu, flash or sdram.
