menuconfig UART_NS16550
	bool "NS16550 serial driver"
	select SERIAL_HAS_DRIVER
	select SERIAL_SUPPORT_INTERRUPT
	help
	  This option enables the NS16550 serial driver.
	  This driver can be used for the serial hardware
	  available on x86 boards.

config UART_NS16550_LINE_CTRL
	bool "Enable Serial Line Control for Apps"
	depends on UART_LINE_CTRL && UART_NS16550
	help
	  This enables the API for apps to control the serial line,
	  such as CTS and RTS.

	  Says n if not sure.

config UART_NS16550_DRV_CMD
	bool "Enable Driver Commands"
	depends on UART_DRV_CMD && UART_NS16550
	help
	  This enables the API for apps to send commands to driver.

	  Says n if not sure.

config UART_NS16750
	bool "Enable UART 16750 (64-bytes FIFO and auto flow control)"
	depends on UART_NS16550
	help
	  This enables support for 64-bytes FIFO and automatic hardware
	  flow control if UART controller is 16750.

config UART_NS16550_ACCESS_WORD_ONLY
	bool "NS16550 only allows word access"
	depends on UART_NS16550
	help
	  In some case, e.g. ARC HS Development kit, the peripheral space of ns
	  16550 (DesignWare UART) only allows word access, byte access will raise
	  exception.
