[U-Boot-Users] PQ2FADS i2c -- no SCL

[Herb Radford]

I've done a recent port of U-Boot 1.0.0 to our MPC866 card and found a 
change was necessary for I2C to do anything (could not get output on SCL or 
SDA).
In the init code for I2c there was a statement which cleared rpbase to 0. 
The docs for the 866 indicate not to change this field!
I commented it out just on a hunch and I2C works!
Try that, maybe it'll help you.

Regards, Herb
