2020-04-01drivers/pc80/rtc: Always load cmos.default if measured boot is enabledBill XIE
cmos.default used to be loaded only when cmos is needed to be reset, but conditional loading of CBFS files may change the calculated PCRs if measurement is hooked on each loading. In order to resolve this, loadings should be made less conditional, (if a file might be used, it should be loaded and measured) but the use of loaded data remains conditional.

2016-11-17rtc: Force negative edge on SET after battery replacementMarshall Dawson
After the RTC coin cell has been replaced, the Update Cycle Inhibit bit must see at least one low transition to ensure the RTC counts. The reset value for this bit is undefined. Examples have been observed where batteries are installed on a manufacturing line, the bit's state comes up low, but the RTC does not count.

2016-11-17rtc: Check update-in-progress bitMarshall Dawson
While the real-time clock updates its count, values may not be correctly read or written. On reads, ensure the UIP bit is clear which guarantees a minimum of 244 microseconds exists before the update begins. Writes already avoid the problem by disabling the RTC count via the SET bit.

2016-05-06rtc: Do checksum check for all bytesStefan Reinauer
Due to missing braces (that went undetected because of the indentation), I584189d9fcf7c9b831d9c020ee7ed59bb5ae08e8 CMOS: add set_option() only takes the last changed byte into regard when determining whether the checksum needs to be updated. This bug went undetected for 5 years.
