void	rtems_put_char (int c, void *unused)
	Puts the character using rtems_putc()

int	putk (const char *s)
	Outputs the characters of the string and a newline character to the kernel character output device.

	RTEMS_PRINTFLIKE (1, 2) int printk(const char *fmt
	Outputs the characters defined by the format string and the arguments to the kernel character output device.

int	vprintk (const char *fmt, va_list ap)
	Outputs the characters defined by the format string and the variable argument list to the kernel character output device.

int	rtems_printk_printer (void unused, const char fmt, va_list ap)
