STM32F427 adding SDRAM with NOR Flash and SSD1963 to FMC

Dear All,

If I use the FMC external bus to drive SDRAM and also some NOR flash and a display via an SSD1963, do you recommend buffering the bus between the SDRAM and the Flash / Display?
I've looked at various application notes for other CPUs, and also the schematics of the new Eval boards, and they seem to contradict each other.
A note on the schematic for the STM324x9I-EVAL board asks for the SDRAM signals (Data / Address / Control) to be the same length, and has no buffer.
Not sure at what length of trace, this becomes critical for the SDRAM.

An application note from ST might help, if one exists? 

Thanks.
