Uboot Into Internal Rom
The AT91RM9200 Development Kits by default have a startup program in the internal 128k of rom. Is there any way to place U-Boot in the internal ROM? Basically, how do I replace the default first level boot on the AT91RM9200 chip?

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.
