serial: ns16550: fix debug uart putc called before init

2019-01-15T20:28:52Z

If _debug_uart_putc() is called before _debug_uart_init(), the ns16550 debug uart driver hangs in a tight loop waiting for the tx FIFO to get empty. As this can happen via a printf sneaking in before the port calls debug_uart_init(), introduce a config option to ignore characters before the debug uart is initialized. This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99). Tested on socfpga_cyclone5_socrates. Signed-off-by: Simon Goldschmidt Reviewed-by: Simon Glass

serial: MediaTek: add high-speed uart driver for MediaTek SoCs

2018-11-29T04:04:53Z

Many SoCs from MediaTek have a high-speed uart. This UART is compatible with the ns16550 in legacy mode. It has extra registers for high-speed mode which can reach a maximum baudrate at 921600. However this UART will no longer be compatible if it's in high-speed mode. Some BootROM of MediaTek's SoCs will change the UART into high-speed mode and the U-Boot must use this driver to initialize the UART.
