Forum Post: Are there any U-boot changes for 16-bit memory vs 8-bit memory?

Hi,

We're designing a custom board based on AM437x EVM that uses 16-bit Micron memory as against 8-bit used by the EVM. Below are both the part numbers.

EVM DDR3 part number - MT41K512M8RH 

Custom board DDR3 part number - MT41K256M16HA-107:E

 

We are working on porting u-boot and linux and I would like to know if there are any changes pertaining to the width of the memory bus. If so, kindly point to the macro that needs to be modified.
