AT91RM9200 fully I2C bus functional

There are dozens of chips using I2C (Inter-IC bus) bus. The AT91RM9200 chip used
in The Sarge SBC project has embedded I2C master controller. Initially I’ve experienced some problems using the bus, but it was hardware/design problem. Now the I2C is fully functional and can be used very easly under linux with applications like lm-sensors. Adding various chips we can read the temperature, pressure, humidity, time etc.
Just for test I have connected DS1621 chip to the board and was able to read the temperature.
