you can find address map from sopc builder of your project.

u-boot will be linked to somewhere near the end of sdram.

check with nios2-linux-uclibc-objdump -h u-boot, to see the vma.

first try to run u-boot from sdram, it is similar to tryout linux, but u-boot replace zimage.

if it works, then you can program it to flash,

http://nioswiki.jot.com/wikihome/operating...flashprogrammer (http://nioswiki.jot.com/wikihome/operatingsystems/flashprogrammer)

it will insert an altera supplied cfi boot loader, which will copy u-boot image from flash to sdram, and jump start on sdram to run u-boot.
