This patch introduces the initial support for stdio library in Galileo platform. For now, only standard output and error are supported. Both streams use the UART1 device. Newlib doesn't call open() for stdin, stdout, and stderr which means that the _write_r call is the first activity the stub will see on those streams. For that reason, we initialize the UART1 device in Galileo's platform main() function instead of in open() system call.
