 yeah i used the printf("U-Boot Ravi at %s:%d!\n", __FILE__,
__LINE__); to confirm . it printed .

 yeah, wil try to do tat. .


>> The statement "my driver code is not gettung[sic] executed when my board boots up" is too vague for us to address.  What do you expect u-boot / your driver to do when it boots up (that it isn't already doing)?

what i meant by the above statement is tat when i insert printf in my
driver code  im not getting anything printed  on console .  so i have
to figure how to plug new spi driver into existing  code and use it.
thanks .
