HI gvb

I was trying to print the status of phy registers by putting some debug
statements in adjust_link function of tsec.c (drivers/tsec.c).

I found that after putting these debugs, i could not recreate the problem
and ethernet works fine.

does this mean there is DDR2 initialization problem in my code..?
