└─>Kernel low-level debugging messages via MVEBU UART0 (new bootloaders)
In linux kernel since version 4 (release Date: 2015-04-12)
Say Y here if you want kernel low-level debugging support
on MVEBU based platforms on UART0.
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.
