Hi BenjaminRoy,
The MCF5223x family of ColdFire microcontrollers does not support external memory for flash, sram and/or dram.
If memory is accessible via SPI or I2C then we have then ability to do so but we do have to start the boot process from internal flash first.
Hope this helps.

Hi BenjaminRoy,
SST and Spansion have external flash memories that have a SPI interface.
You could bit bang a protocol on GPIO for the memory sticks you've sent links to but that bandwidth would be far less than using the intergrates SPI bus.
I do not have an example SPI to Flash schematic.
