config EEPROM_AT24
|

tristate "I2C EEPROMs / RAMs / ROMs from most vendors"
|
|
depends on I2C && SYSFS
|
|
help
|
|
Enable this driver to get read/write support to most I2C EEPROMs
|
|
and compatible devices like FRAMs, SRAMs, ROMs etc. After you
|
|
configure the driver to know about each chip on your target
|
|
board. Use these generic chip names, instead of vendor-specific
|
|
ones like at24c64, 24lc02 or fm24c04:
|
|
|
|
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.

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

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.

If you say yes here you get read-only support for the user EEPROM of
|
|
the Maxim MAX6874/5 EEPROM-programmable, quad power-supply
|
|
sequencer/supervisor.
|
|
|
|
All other features of this chip should be accessed via i2c-dev.
|
|
|
|
This driver can also be built as a module. If so, the module

|

erase the whole EEPROM.
|

help
|

This option enables access to display configuration EEPROMs
|
|
on digsy_mtc board. You have to additionally select Microwire
|
|
EEPROM 93XX46 driver. sysfs entries will be created for that
|
|
EEPROM allowing to read/write the configuration data or to
|
|
erase the whole EEPROM.

help
|
|
This is a driver for the 'security ID' available on various Allwinner
|
|
devices.
|
|
|
|
Due to the potential risks involved with changing e-fuses,
|
|
this driver is read-only.
|
|
|
|
This driver can also be built as a module. If so, the module
|
|
will be called sunxi_sid.
