    I have never seen that board before but that appears to be a serial flash device (SPI). So you would need a SPI master to access it, these are something called "3 wire" devices. You will need a driver to access it. That flash might be an EPCS128 device in which case you can just use the EPCS controller to access it from software.

    Also did you try out any the designs that came with the board? The webpage suggests there are pre-cooked designs ready for the board already.

    The SPI core in SOPC Builder/Qsys should be able to access it if you parameterize it correctly. You will need to write a software driver to access it since there is a protocol on top of the SPI protocol necessary to read/write to SPI flash devices.
