Hi experts

I plan to use i.mx285 to design a gateway product. I want to know that how many layers of the pcb is Suitable for my design?(especially how many signal layers?)

The peripheral which I will use is that: 1 i2c, 2 spi, 3 uart, 1 sdio, 1 audio interface, 2 can, 2 usb, flash + DDR2, no ethernet and no graphic interface(LCD)

and the area of the pcb is rich.

There is a reference design:
