interfacing RTC module to hps driven i2c pins

Hi Snehal

I am not too sure on what could cause the kernel hang but I would suggest you use a newer version of the linux kernel.

From my experience with RS232, I have not seen a software flow control for RS232.

The RS232 got lots of hardware flow control that we could utilize.

I could be wrong on this statement.

However I managed to find this RS232 example from the Intel website.
