Rajasekaran,
The EVM has never failed to boot from SPI NOR (i.e., without using the emulator). However it also never gives a name for the SO-DIMM.
When I remove the SO-DIMM, I get an error and it hangs:
U-Boot 2013.01 (Nov 24 2013 - 16:43:18) I2C: ready Cannot read DIMM params Detected SO-DIMM [] But with the DIMM installed, it boots fine. Below is the u-boot output with the SO-DIMM installed booting directly from SPI NOR (I cut it off during kernel boot, but that always works as well):

I looked at init_ddr3 in ddr3.c (u-boot) and the name is checked against the one you show in your log. If it matches, then it configures at 400MHz, otherwise it uses 333MHz.
The SO-DIMM on my board is marked as 2GB and has an Advantech sticker on it.
I also notice that your log shows a total of 8GiB while mine only show 2GiB. Is yours the same board type as mine (Advantech K2-EVM-HK)?
Thanks,
Lance
