Files /SDK to have Linux on ALTERA on NIOS-2

Dear All ,

This is my first thread on altera and first project hence apologies if there is an mistake in my understanding.

1) Could group members point me to Linux SDK files that can be used (Tool-chain , Boot-loader , Kernel , File-system etc)

to have Linux on Altera Stratix IV GX FPGA Board.

2) Could team members please provide any tutorial / application notes / wiki providing steps to do so ?

Thanks ,
