Hi Jagan,
Seems like your and Kurt's board have different DRAM type:
- 16bit row + 1 CS
- 15bit row + 2 CS
Capacity detect function is missing for the driver now, and it's not able
to detect the correct size like Kurt is using.
Thanks,
- Kever

The board has 4G memory but only 2G is detected by TPL. Please
let me know if additional information is needed.

Please check it I can able to detect 2GB each channel, so total 4GB.
