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.

This is the bootloader's responsability. If you use an EPCS controller, the bootloader is included. Just set the CPU to boot on the EPCS controller. If you use a parallel flash, set the CPU to boot on it and the Nios programmer will flash the bootloader for you.
