The IFC interface is not very high-speed interface, 100 Mhz max, so there is no specific board layout recommendations.
The only general recommendations could be given:
1. Match signal length for data and control signals for easy understanding of signal timings at remote side
2. Route all signals on the same layer - for same reason, to make signal propagation time to be the same.
3. Use impedance matching techniques to reduce signal ringing on long traces, minimize stubs.
Have a great day,
Alexander
