The Identification Page (32 byte) is an additional page which can be written and (later) permanently locked in Read-only mode.
phyCORE-RK3288 SoMs are using this page to describe the module variant. This page also contains a MAC.
Our boards can be equipped with a different amount of EEPROMs. To make this more transparent let's add an alias for the eeprom which stores the module variant.
