If you are going for a simple and cheap solution than using only an serial SPI flash (EPCS) is better.

The epcs can hold both the hardware configuration image and the software. A parallel flash would be needed, if you need a very high read speed, or very large amounts of flash.

EPCS and other SPI flash chips

- sizes from 1Mbit to 64Mbit (usualy op to 512kB are used for the hardware image, the rest can be used for software and flash file systems)

- read speed of 1MB/s is easily achievable
