Simple NIOS-II simulator instruction decode

This code implements a simple NIOS-II cpu; It's not a complete or
generalized implementation, however.  I only need to simulate a small
amount tightly coupled instruction memory and tightly coupled data
memory and data ddr2 (sdram).

The memorys are in fixed locations.  You'll have to modify mem.c to suit
your implementation.

The loader will read an arbitrary elf file generated by the nios toolchain.
