Hi Simon,

Probably in include/arch/arm/at91sam9260.h. Or, if you don't want to 
modify system files, you can add

   HWDEF+=-DEBI_HAS_CSA

in UserConf.mk of your build directory. However, be aware, that the 
SDRAM must be initialized before using it, typically in

   nut/arch/arm/init/crtat91sam9260_*.S

You can find a sample in crtat91sam7se512_rom.S.
