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.
