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

NuttX per default reorders the serial ports (/dev/ttySx) so that the
|
||||||
|
console is always on /dev/ttyS0. If more than one UART is in use this
|
||||||
|
can, however, have the side-effect that all port mappings
|
||||||
|
(hardware USART1 -> /dev/ttyS0) change if the console is moved to another
|
||||||
|
UART. This option disables that re-ordering for 16550 UARTs.
