[U-Boot] Help neede on MPC8315 I2C Interface

[vtvasan v]

Hi all,

             i am working on MPC8315 based board and i am able to port the U-Boot with 
(VERSION = 2009, PATCHLEVEL = 11, SUBLEVEL = 1). In my board one Temperature sensor chip is connected and i am not able to access the chip from u-Boot. The processor is getting initialized during power-up using I2C EEPROM but once powered up U-Boot is giving time out error when ever i am trying to access the EEPROM and  temperature sensor. when i probe the clock signal it is coming only when the processor is getting initialized from the EEPROM. i have disabled the the PCI interface in U-boot since in my board no PCI devices are there.

please help me to find out why there is no activity in MPC8315 I2C interface once U-Boot got loaded. 

Thanks,
