EEPROM write protect

[ashevche]

The addresses 0x30...0x37 can be used by the EEPROM chips as explained in the Linux kernel documentation:

The Microchip 24AA52/24LCS52, ST M34C02, and others support an additional software write protect register at 0x30 - 0x37 (0x20 less than the memory location).
