My platform is Intel Denverton with Coreboot 4.8.1 and it can boot up successfully except RTC. There is always an error like “unable to open rtc device (rtc0)” when I try to set clock. But if I use BIOS to boot up again, this error will be disappeared and later boot up with Coreboot and setup hwclock successfully. Does anyone have same experience and know how to fix it? Thanks.
