Reconfigure FPGA another using NIOS II SoC

There are plenty of ways to dynamically reconfigured FPGAs. However, the development kits you have listed probably do not support reconfiguration by another board, simply because that is not something needed on a development board.

The four FPGAs on this board are dynamically reprogrammed by the PowerPC and FPGA seen on the right-side of the image:

This document describes reconfiguration:

A NIOS II processor could be used to enable a reconfiguration controller like this, or it could "bit-bang" the passive serial interface on the FPGA.
