SDRAM internal bank config

I am getting confused about how to configure internal SDRAM banks, as per EE-276.  I have two 16-bit SDRAMs connected in parallel as 32-bits to the EBIU.  Each device has 4 internal banks, and the BF561 can optimize fetches to and from different banks.  How do I configure the memory declarations and LDF to keep the code in bank0, the readBuffer in bank1, and the writeBuffer in bank2?

 

I admit that I got mixed up by internal vs external banks.

 

The SDRAM devices are: MT48LC23M16 (8M x 16b x 4 banks).

 

TIA.
