CONFIG_SERIAL_8250_FSL: Freescale 16550 UART support

General informations

The Linux kernel configuration item CONFIG_SERIAL_8250_FSL has multiple definitions:

Freescale 16550 UART support found in drivers/tty/serial/8250/Kconfig

The configuration item CONFIG_SERIAL_8250_FSL:

• prompt: Freescale 16550 UART support
• type: tristate
• depends on: ( CONFIG_COMPILE_TEST && !( CONFIG_PPC || CONFIG_ARM || CONFIG_ARM64 )) && ( CONFIG_SERIAL_8250 ) && ( CONFIG_PPC || CONFIG_ARM || CONFIG_ARM64 )
• defined in drivers/tty/serial/8250/Kconfig
• found in Linux kernels: 6.5–6.11, 6.12-rc+HEAD
• modules built: 8250_fsl

Help text

Selecting this option enables a workaround for a break-detection erratum for Freescale 16550 UARTs in the 8250 driver. It also enables support for ACPI enumeration.
