Ok ... can you debug the board_init_f/relocate_code/board_init_r functions?
Where is your relocate_code() destination address (it is calculated in
board_init_f())?
Is relocate_code() reached?
Does the fixup loop's run? (don't forget to reload symbol file as
described in doc/README.arm-relocation)
Is board_init_r() reached?
...

at91rm9200dk uses the deprecated arm920t/at91rm9200 stuff and is known
to be broken currently! The arm920t/at91rm9200 code will be deleted in
near future! (and so at91rm9200dk board, if you have one handy please
try to get it working with arm920t/at91 files). If your board uses
arm920t/at91rm9200 configuration please convert it to arm920t/at91 ASAP!

Sorry, I can not help here cause I didn't get dataflash working with
at91rm9200ek yet.

Well I own an at91rm9200ek and use the at91rm9200ek_ram_config to build
(is mainline). The NOR flash booting is currently broken but getting
this working is my next target.

Dataflash for at91 targets in principle is currently somewhat
broken/unreliable/defective API (there was a discussion these days,
search the list).
