two threads on porting linux on ppc7a, There
he mentioned ppc7a board is similar to EV64260  board. I tried to get 
the data sheets of EV64620, i failed to found this
board data sheets. If any one has this board data sheets , web link or 
any information please send the information to me.
Thanks and regards,
