Since commit 7b3b74d32127 ("serial: serial_stm32: Enable overrun") on STM32F7xx based boards, the first lines of serial output are missing during boot (we no more see the U-Boot release version, board model and DRAM size).
By enabling the uart FIFO on STM32F7, the complete U-boot log can be sent correctly.
