Where is SDRAM initilization done?

I am trying to build a NIOS system with SDRAM. On an ARM SoC, usually software do the SDRAM initilization. But on NIOS system, I do not find who takes this job. Can anyone help to explain? Thanks.

It seems that there is no need for software to do initialization.

That's generally true for the Altera SDRAM controllers I know. On the other hand, the controller interface doesn't offer any means to send configuration parameters to the RAM, this should also answer your question.
