MCF52259 mini-flex-bus series resistance. Is it really necessary?

I am re-spinning my MCF52259 board for a third time now and I am thinking about dropping the 22 ohm series resistance on the mini-flex-bus pins.I originally based my design on the MCF52259 EVB schematic that used the bus for external flash. It had the little resistors. My board connects to 8 static ram chips. I use a multiplexer to control the chip selects.
