From f651022df366565871ca28bff644c049f46bcf0e Mon Sep 17 00:00:00 2001 From: Angel Pons Date: Thu, 17 Dec 2020 11:51:36 +0100 Subject: mb/prodrive/hermes: Drop EEPROM address function parameters Only one EEPROM is used to store the board settings, and its I2C address is constant. Thus, there's no need to pass its address as a parameter. In addition, reduce the scope of the `I2C_ADDR_EEPROM` definition, since using it outside of eeprom.c would bypass the API's abstraction layer.
