How to set DDR data bus width to 16Bit

[Frank Prepelica]

Hi all,

Does anyone knows how to set the DDR data bus width to 16Bit in linux?
I've found that 
option in U-Boot in the MPC8313ERDB_config file. (verfied with a memory
dump of the 
CPU register (DDR_SDRAM_CFG)  - the 16Bit DBW is set(10b) ). But after
starting 
linux the value is set to 00b (=reseverd).

We are using a customized MPC8313ERDB board.

Thanks in advance


Kind regards
