Reset any i2c devices that may have been interrupted by a system reset. Normally this would be accomplished by clocking the line until SCL and SDA are released and then sending a start condtiion (From an Atmel datasheet). But since there is only write access to these lines on the MPC5200 we can only attempt to reset any slave devices by sending more start commands than bits the slave is attempting to transmit.

Other than the "#define CONFIG_MISC_INIT_F 1" change, the modifications to include/configs/galaxy5200.h should be separated out into a different patch (if you want to have them committed) as they don't have anything to do with the patch's title and description.
Best, Peter
