Hi all,
   I made a u-boot binary with the custom configuration for my 8260 
board.  I am using SMC2 as the serial device. When I boot using BDI, It 
comes upto the boot prompt and does not receive characters.  When I don't 
use BDI, it does not even come to the command prompt, it crashes in 
between, I don't know why?.  I am guessing that the serial driver reception 
is broken?.  I was looking at the serial driver code, looks like it is 
using polling mechanism instead of interrupts.  Is the problem points to 
the serial clks or the driver itself?  Has anyone used SMC2 as the serial 
driver in the U-boot code.  I was comparing the getc function of 
smc_serial.c and uart.c, one is using the while loop to wait and the other 
is using the for loop to wait, does it make a difference.  Can anyone tell 
me what is going on?
