CONFIG_DEBUG_MVEBU_UART_ALTERNATE: Kernel low-level debugging messages via MVEBU UART (new bootloaders)

General informations

The Linux kernel configuration item CONFIG_DEBUG_MVEBU_UART_ALTERNATE:

• prompt: Kernel low-level debugging messages via MVEBU UART (new bootloaders)
• type: bool
• depends on: CONFIG_ARCH_MVEBU
• defined in arch/arm/Kconfig.debug
• found in Linux kernels: 3.11–3.19

Help text

Say Y here if you want kernel low-level debugging support on MVEBU based platforms.

This option should be used with the new bootloaders that remap the internal registers at 0xf1000000.

If the wrong DEBUG_MVEBU_UART* option is selected, when u-boot hands over to the kernel, the system silently crashes, with no serial output at all.
