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 64-bytes FIFO for UART 16750"
depends on UART_NS16550
help
This enables support for 64-bytes FIFO 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.
