[Avila] External I2C on 2345 (or 2348)

[John Carter]

I have a need to connect some external I2C addressable components to  
a 2345 board and it doesn't look like the SCL and SDA lines from the  
I2C bus used to communicate with the on-board devices are brought out  
to headers anywhere.  I could use two of the 5 available GPIO lines,  
but I need all of those for other interfaces.

So I guess I have two questions:

1. Do the I2C SDA and SCL lines appear on one of the headers  
somewhere that is not documented?

2. Are there any additional GPIO lines anywhere on the board that can  
be used externally?

Thanks,
