should work. Maybe you run into trouble cause of missing armv4 support
in the toolchain. There are workarounds, just let u-boot build its own
libgcc stuff -> 'USE_PRIVATE_LIBGCC'.

Well, please update this board to use the new arm920t/at91 SoC code, see
at91rm9200ek for example.

At least these steps are missing:
- configure to use arm920t/at91, not arm920t/at91rm9200 (-> boards.cfg)
- set correct USART in config
- adopt includes in board file
