	  Enable this driver to get read/write support to most I2C EEPROMs,
	  after you configure the driver to know about each EEPROM on
	  your target board.  Use these generic chip names, instead of
	  vendor-specific ones like at24c64 or 24lc02:

	     24c00, 24c01, 24c02, spd (readonly 24c02), 24c04, 24c08,
	     24c16, 24c32, 24c64, 24c128, 24c256, 24c512, 24c1024

	  Unless you like data loss puzzles, always be sure that any chip
	  you configure as a 24c32 (32 kbit) or larger is NOT really a
	  24c16 (16 kbit) or smaller, and vice versa. Marking the chip
	  as read-only won't help recover from this. Also, if your chip
	  has any software write-protect mechanism you may want to review the
	  code to make sure this driver won't turn it on by accident.

	  If you use this with an SMBus adapter instead of an I2C adapter,
	  full functionality is not available.  Only smaller devices are
	  supported (24c16 and below, max 4 kByte).

	  This driver can also be built as a module.  If so, the module
	  will be called at24.
