MCF52233 and external RAM

Hi all. I have a doubt regarding the MCF52233: can it manage anyhow an external RAM, so I can expand the 32 kb of the uC?

I have this doubt because I have run out of in chip RAM, but I have an external SPI EEPROM, which I want to use as a RAM memory, so I haven't got to change the board nor the program.

 

It would be fine if I can manage it using the .lcf, and (maybe?) handling the exception error to access to the external memory.

 

Can something like this be done?

 

Thanks in advance,

Ruben
