This is being used by other drivers which are dependent on serial. menu "Serial Port Options" config SERIAL_INTERRUPT_LEVEL bool "Serial interrupt level" depends on IOAPIC default y help Option signifies that the serial controller uses level interrupts instead of edge config SERIAL_INTERRUPT_LOW bool "Serial interrupt low" depends on IOAPIC default n help Option signifies that the serial controller uses low level interrupts instead of high config UART_INTERRUPT_DRIVEN bool prompt "Interrupt driven UART support" default n help This option enables interrupt support for UART allowing console input and UART based drivers. endmenu config NS16550 bool "NS16550 serial driver" default n select SERIAL_HAS_DRIVER help This option enables the NS16550 serial driver. This driver can be used for the serial hardware available on x86 platforms such as basic_atom and basic_minuteia. config NS16550_PCI bool "NS16550 PCI serial driver" default n depends on PCI && NS16550 help This enables NS16550 to probe for PCI-based serial devices. This option enables the driver to auto-detect the device configuration required to access those ports. config NS16550_PORT_0_BASE_ADDR hex "NS16550 port 0 PCI base address" default 0x00000000 depends on NS16550_PCI config NS16550_PORT_1_BASE_ADDR hex "NS16550 port 1 PCI base address" default 0x00000000 depends on NS16550_PCI config K20_UART bool "K20 serial driver" default n select SERIAL_HAS_DRIVER help This option enables the K20 serial driver. This specific driver can be used for the serial hardware available at the Freescale FRDM K64F platform. config STELLARIS_UART bool "Stellaris serial driver" default n select SERIAL_HAS_DRIVER help This option enables the Stellaris serial driver. This specific driver can be used for the serial hardware available at the Texas Instrument LM3S6965 platform. config UART_PORT_0_NAME string default "UART_0" help This is the device name for UART, and is included in the device struct. config UART_PORT_1_NAME string default "UART_1" help This is the device name for UART, and is included in the device struct. config UART_PORT_2_NAME string default "UART_2" help This is the device name for UART, and is included in the device struct. config UART_PORT_3_NAME string default "UART_3" help This is the device name for UART, and is included in the device struct. config UART_PORT_4_NAME string default "UART_4" help This is the device name for UART, and is included in the device struct. config UART_PORT_5_NAME string default "UART_5" help This is the device name for UART, and is included in the device struct. config UART_PORT_6_NAME string default "UART_6" help This is the device name for UART, and is included in the device struct. config UART_PORT_7_NAME string default "UART_7" help This is the device name for UART, and is included in the device struct. endif
