The board_early_init_f() inits clock before initing pinmux. However, the clock configuration code might need to adjust PMIC settings of a PMIC on I2C bus (e.g. board/ti/am335x/board.c does that). If the I2C bus pin muxing is not configured before attempting to communicate with the PMIC, the communication will silently fail and the prcm_init() may configure fast enough CPU clock that the default voltage provided by the PMIC would be insufficient and the platform would become unstable.
