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.

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.
