Xiang Xiao 46e47c8dcf Squashed commit of the following: ... drivers/serial/uart_16550.c: Add a configuration, analogous to the STM32 configuration option, to suppress the NuttX standard re-ordering for /dev/ttySN for special case of the 16550 UART. config/serial: UART 16550: Add CONFIG_SERIAL_UART_ARCH_MMIO option so the a memory mapped device doesn't need to provide uart_getreg() and uart_putreg() implementations. u16550_txempty() should check UART_LSR_TEMT to avoid some data left in the transmit FIFO		2018-08-26 11:17:33 -06:00
