An alternative Flash memory for Cyclone5

We used Winbond W25Q128JVPIQ series on a Cyclone V GX board and it worked. Make sure it is the IQ suffix. You must use Quartus 17.1 or later and select, in this case, EPCQ128A in AS x4 when you generated the programming file. Of course for different sizes replace 128 with your size.
