As some advised, instead of trying to write a boot loader for a custom AT91 board, I wanted to use the loader.bin and u-boot.bin from ATMEL.
Even better just use U-Boot and forget about loader.bin ...
My alternate question is, how to port u-boot, so that I can start it in RAM with the above configuration (I've got a small boot loader done in assembly, which is loaded from SPI on startup. So I could store u-boot in the SPI flash, and load it to RAM from there on startup by my small boot loader. how to do this? eg. where to load the u-boot image in RAM? I guess I have to also adjust the SDRAM setup and timings which are differing from the atmel DK.). have anyone ported u-boot to such a configuration?
Instead of doing all this which is really non-trivial and also ineffficient you could just boot from flash. I've just checked in the necessary patches for the AT91RM9200DK and CMC_PU2 boards ...
