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.
