Are you sure your local bus runs at 100 MHz?
Check your clock routing!!
What about CONFIG_CONS_EXTC_RATE and CONFIG_CONS_EXTC_PINSEL ?
Still am not getting any think on console, The SMC ports are inbuilt, it needs any serial driver to modify or any other files? Please suggest me to come out of this problem.
Attach a scope to the pins and check if there is output, just at an unexpected baud rate.
If this doesn't help, then get yourself a JTAG debugger and start GDB.
