On STMicroelectronics boards, the UART can reliably go up to 2000000 bauds when connected to the on-board ST-LINK-V2 for STM32MP15 Unfortunately U-Boot will fall back to 115200 unless higher rates are declared via CONFIG_SYS_BAUDRATE_TABLE. This patch add the support of higher baudrates on STMicroelectronics boards with ST-LINK.
