While we are there, you will also see that init_baudrate() and serial_init() is called even much earlier than this, and for example all systems that store the environment in EEPROM will have to read the baudrate from the EEPROM - and thus need to initialize the I2C controller. I don;t know how many of these boards are still in practical use (I know at least one [pcu_e] which has long reached EOL), but this still leves > 10 affected boards in mainline. > So it would appear that most scenarios are already covered for 8xx. How Most is not all, and here probably not good enough.
