This causes barebox serial console to be non functional. To solve the problem this software-only clocksource driver is used. WARNING!!! This clocksource doesn't provide correct timing. To adjust this clocksource please use CONFIG_CLOCKSOURCE_DUMMY_RATE. The bigger rate valuest makes clocksource "faster". It's possible to add this clocksource unconditionally. This clocksource starts very early (pure_initcall) so real clocksource will take over. This can help if initialization order is wrong so that the time functions are used before the real clocksource was initialized. config CLOCKSOURCE_DUMMY_RATE int prompt "dummy clocksource rate" depends on CLOCKSOURCE_DUMMY default 1000 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
