Right. Messages should appear after a few milliseconds when booting
from NOR.

Ya you are right.

U-Boot will start printing messages long before it starts accessing
the RAM.

So I dont think any issue in the DDR2 RAM initialization in my case.

Misconfiguration of your hardware / port?  Eventually you are running
at an extremely slow clock rate?

CPU clock is at higher rate 660MHz which is the maximum clock for this
series of CPU, how port information can be wrong as I am getting the
messages on console on this port.

May be misconfiguration and initialization of NOR Flash taking more time, it
is not getting chip select at right time, this is my understanding. Please
let me know if any thing I need to cross verify in this regard.
