This causes barebox serial console to be non functional. To solve the problem barebox has built-in software-only clocksource. The software-only clocksource is used only if no hardware clocksource is registered. This can help if initialization order is wrong so that the time functions are used before the real clocksource was initialized. WARNING!!! Built-in software-only clocksource doesn't provide correct timing. The option CONFIG_CLOCKSOURCE_DUMMY_RATE is used to adjust this clocksource. The bigger rate valuest makes clocksource "faster". config CLOCKSOURCE_MVEBU bool depends on ARCH_MVEBU config CLOCKSOURCE_NOMADIK bool depends on ARM config CLOCKSOURCE_ORION bool depends on ARCH_MVEBU config CLOCKSOURCE_UEMD bool depends on ARCH_UEMD config CLOCKSOURCE_ROCKCHIP bool depends on ARCH_ROCKCHIP
