## Summary
The Beaglebone black BSP console driver currently only works if the BSP is
built with CONSOLE_POLLED configuration. When built with CONSOLE_POLLED = False
(i.e. interrupt driven mode), the console driver doesn't accept input.
## Steps to reproduce
Build the Beaglebone black BSP with CONSOLE_POLLED = False and run the
following test application:
`#include <sys/stat.h>
#include <fcntl.h>
#include <stdio.h>
#include <unistd.h>
#include <assert.h>
#include <stdlib.h>
#include <sys/ioctl.h>
#include <rtems.h>
#include <bsp/beagleboneblack.h>
#include <bsp/gpio.h>
#include <bsp/i2c.h>
static void Init(rtems_task_argument arg) {
rtems_status_code status;
printf("Starting Console testing\n");
printf("Enter a string up to 80 characters:\n");
char buf[80] = "";
char *cmd, *sval, *rval;
int num_bytes = read(STDIN_FILENO, buf, sizeof(buf));
printf("You entered: %s\n", buf);
status = rtems_task_delete( RTEMS_SELF); /* should not return */
printf("rtems_task_delete returned with status of %d.\n", status);
exit(1);
}

When the BSP will not accept any input, but will immediately return an empty
output as per the following:
`....
Starting kernel ...
RTEMS Beagleboard: am335x-based
ARM Debug: 0x4b141000
Starting Console testing
Enter a string up to 80 characters:
You entered:
`
## Expected behaviour
When the BSP is built with with CONSOLE_POLLED = False, the example application
above will accept input and display it back to the user like this:
`....
Starting kernel ...
RTEMS Beagleboard: am335x-based
ARM Debug: 0x4b141000
Starting Console testing
Enter a string up to 80 characters:
This is a test string
You entered: This is a test string`
