All Keymile boards have an EEPROM that is called IVM that contain information about the board that is progammed at production time. One piece of information is the MAC addresses assigned to the board.
u-boot requires the MAC address of the ethernet interfaces it uses to be defined when the interface is intialized. This is most of the time read from the environment but in the case where only the default environment is available, this must be read from somewhere else, in our case the IVM.
This patch series splits the reading and analysis of the IVM content in 2, so that the IVM content and MAC addresses can be read prior to ethernet initialization. The analysis of the rest of the IVM content still happens at a later second stage.
Changes in v2: - Include the first patch, which was forgotten in the first submission
Valentin Longchamp (6): KM/IVM: split the IVM reading and parsing in 2 parts kirkwood/km_arm: read the IVM eeprom earlier 85xx/kmp204x: read the IVM eeprom earlier 83xx/km83xx: read the IVM eeprom earlier 82xx/km82xx: read the IVM eeprom earlier KM/IVM: remove ivm_read_eeprom(void)
