Use these generic chip names, instead of 10 vendor-specific ones like at24c64 or 24lc02: 11 12 24c00, 24c01, 24c02, spd (readonly 24c02), 24c04, 24c08, 13 24c16, 24c32, 24c64, 24c128, 24c256, 24c512, 24c1024 14 15 Unless you like data loss puzzles, always be sure that any chip 16 you configure as a 24c32 (32 kbit) or larger is NOT really a 17 24c16 (16 kbit) or smaller, and vice versa. Marking the chip 18 as read-only won't help recover from this. Also, if your chip 19 has any software write-protect mechanism you may want to review the 20 code to make sure this driver won't turn it on by accident. 21 22 If you use this with an SMBus adapter instead of an I2C adapter, 23 full functionality is not available. Only smaller devices are 24 supported (24c16 and below, max 4 kByte). 25 26 This driver can also be built as a module. If so, the module 27 will be called at24. 28 29config EEPROM_AT25 30 tristate "SPI EEPROMs from most vendors" 31 depends on SPI && SYSFS 32 help 33 Enable this driver to get read/write support to most SPI EEPROMs, 34 after you configure the board init code to know about each eeprom 35 on your target board. 36 37 This driver can also be built as a module. If so, the module 38 will be called at25. 39 40config EEPROM_LEGACY 41 tristate "Old I2C EEPROM reader" 42 depends on I2C && SYSFS 43 help 44 If you say yes here you get read-only access to the EEPROM data 45 available on modern memory DIMMs and Sony Vaio laptops via I2C. Such 46 EEPROMs could theoretically be available on other devices as well. 47 48 This driver can also be built as a module. If so, the module 49 will be called eeprom. 50 51config EEPROM_93CX6 52 tristate "EEPROM 93CX6 support" 53 help 54 This is a driver for the EEPROM chipsets 93c46 and 93c66. 55 The driver supports both read as well as write commands. 56 57 If unsure, say N. 58 59endmenu 60
