>Description:
The i2c-tools package contains a heterogeneous set of I2C tools for
Linux: a bus probing tool, a chip dumper, register-level SMBus access
helpers, EEPROM decoding scripts, EEPROM programming tools, and a python
module for SMBus access.
Only DIMM SPD decoding tool is ported at the moment.
