[U-Boot] i2c on mx27

Hi,

Has anyone tried playing with the hardware i2c on the mx27 platform using u-boot. I am trying to enable the second controller and use hardware i2c by doing memory writes to the appropiate registers using "mw". Looks like i am missing out on some register values. I am unable to toggle the signals on the I2C2_CLK and I2C2_data lines. I have modifed the mux registers and the pad registers and the Clock gating registers appropiately. Any hints? Thanks, Alfred.
