+config EEPROM_AT24
+ tristate "I2C EEPROMs from most vendors"
+ depends on I2C && SYSFS && EXPERIMENTAL
+ help
+ 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.
+
+config EEPROM_AT25
+ tristate "SPI EEPROMs from most vendors"
+ depends on SPI && SYSFS
+ help
+ Enable this driver to get read/write support to most SPI EEPROMs,
+ after you configure the board init code to know about each eeprom
+ on your target board.
+
+ This driver can also be built as a module. If so, the module
+ will be called at25.
+
+config EEPROM_LEGACY
+ tristate "Old I2C EEPROM reader"
+ depends on I2C && SYSFS
+ help
+ If you say yes here you get read-only access to the EEPROM data
+ available on modern memory DIMMs and Sony Vaio laptops via I2C. Such
+ EEPROMs could theoretically be available on other devices as well.
+
+ This driver can also be built as a module. If so, the module
+ will be called eeprom.
+
+config EEPROM_93CX6
+ tristate "EEPROM 93CX6 support"
+ help
+ This is a driver for the EEPROM chipsets 93c46 and 93c66.
+ The driver supports both read as well as write commands.
+
+ If unsure, say N.
