 468           Enables the ETRAX general port device (major 120, minors 0-4).
 469           You can use this driver to access the general port bits. It supports
 470           these ioctl's:
 471           #include <linux/etraxgpio.h>
 472           fd = open("/dev/gpioa", O_RDWR); // or /dev/gpiob
 473           ioctl(fd, _IO(ETRAXGPIO_IOCTYPE, IO_SETBITS), bits_to_set);
 474           ioctl(fd, _IO(ETRAXGPIO_IOCTYPE, IO_CLRBITS), bits_to_clear);
 475           err = ioctl(fd, _IO(ETRAXGPIO_IOCTYPE, IO_READ_INBITS), &val);
 476           Remember that you need to setup the port directions appropriately in
 477           the General configuration.
