	   This option enables the host functionality of the ETRAX 100LX
	   built-in USB controller. In host mode the controller is designed
	   for CTRL and BULK traffic only, INTR traffic may work as well
	   however (depending on the requirements of timeliness).

config ETRAX_PTABLE_SECTOR
	int "Byte-offset of partition table sector"

	help
	  Byte-offset of the partition table in the first flash chip.
	  The default value is 64kB and should not be changed unless
	  you know exactly what you are doing. The only valid reason
	  for changing this is when the flash block size is bigger
	  than 64kB (e.g. when using two parallel 16 bit flashes).

config ETRAX_I2C

	  Enables an I2C driver on ETRAX100.

	  i2c_arg = I2C_WRITEARG(STA013_WRITE_ADDR, reg, val);
	  ioctl(fd, _IO(ETRAXI2C_IOCTYPE, I2C_WRITEREG), i2c_arg);

	  Select whether to use the special I2C mode in the PB I/O register or
	  not.  This option needs to be selected in order to use some drivers
	  that access the I2C I/O pins directly instead of going through the

	  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);

	  val = ioctl(fd, _IO(ETRAXGPIO_IOCTYPE, IO_READBITS), NULL);
	  Remember that you need to setup the port directions appropriately in
	  the General configuration.
