How to connect secondary SPI NOR flash on FM4 S6E2GM Pioneer Kit Arduino interface

Hi Sir, 

I would like to have my WSON8 socket connect with Arduino interface to test SPI NOR flash. 
The FM4 S6E2GM Pioneer Kit has free pins on Arduino interface or even there is SPI interface 
available(not sure yet because the schematic connect to JTAG?). And that's why I want to use that interface to connect with. Is that doable not only hardware but also software? 

The next question will be how SPI interface looks like support single IO on schematic now. 
How to support Quad mode on schematic and software? 

Thanks, 
Michael
