Description
APOLLOLAKE S/L motherboard is equipped with accurate external RTC chip. It can hold the time
accurately under absence of NTP time server.
The RTC timer works together with internal PCH timer on processor.
When OS is running, User APP is updating PCH time at runtime. During System boot, BIOS will copy
the timer from external RTC to internal PCH.
