Enables I2C EEPROM (non-volatile RAM) on PB0 and PB1 using the I2C
driver. Select size option: Probed, 2k, 8k, 16k.

---help---
Enables the ETRAX general port device (major 120, minors 0 and 1).
You can use this driver to access the general port bits. It supports
these ioctl's:
#include <linux/etraxgpio.h>
fd = open("/dev/gpioa", O_RDWR); // or /dev/gpiob
ioctl(fd, _IO(ETRAXGPIO_IOCTYPE, IO_SETBITS), bits_to_set);
ioctl(fd, _IO(ETRAXGPIO_IOCTYPE, IO_CLRBITS), bits_to_clear);
val = ioctl(fd, _IO(ETRAXGPIO_IOCTYPE, IO_READBITS), NULL);
Remember that you need to setup the port directions appropriately in
the General configuration.
