CONFIG_DEBUG_VEXPRESS_UART0_DETECT: Autodetect UART0 on Versatile Express Cortex-A core tiles

General informations

The Linux kernel configuration item CONFIG_DEBUG_VEXPRESS_UART0_DETECT:

• prompt: Autodetect UART0 on Versatile Express Cortex-A core tiles
• type: bool
• depends on: CONFIG_ARCH_VEXPRESS && CONFIG_CPU_CP15_MMU
• defined in arch/arm/Kconfig.debug
• found in Linux kernels: 3.6–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.10, 6.11-rc+HEAD

Help text

This option enables a simple heuristic which tries to determine the motherboard's memory map variant (original or RS1) and then choose the relevant UART0 base address.

Note that this will only work with standard A-class core tiles, and may fail with non-standard SMM or custom software models.
