2023-01-18soc/intel/cannonlake: Fix incorrect `prev_sleep_state` issueSubrata Banik
The patch fixes indication of incorrect `prev_sleep_state` on the next boot after global reset trigger. The existing code misses an important check about `if PCH doesn't set the WAK_STS` while checking power failure. As a result, every early warm/global reset is considered as power failure after looking into the PMC MMIO CON-A register alone (as ignoring the ACPI PM_CTRL.WAK_STS bit). As per the code comment this code logic is expected to check the power failure reason if PCH doesn't set the WAK_STS while waking from G3 state. TEST=Able to build and boot google/hatch. Without this patch: Observation: Resuming after a warm reset is considered as `prev_sleep_state 5` although the SLP_TYP is zero and WAK_STS bit is set. pm1_sts: 8100 pm1_en: 0000 pm1_cnt: 00000000 GEN_PMCON: d1215238 00002200 .... prev_sleep_state 5 With this patch: Observation: Resuming after a warm reset is considered as `prev_sleep_state 0`.

They're listed in AUTHORS and often incorrect anyway, for example: - What's a "Copyright $year-present"? - Which incarnation of Google (Inc, LLC, ...) is the current copyright holder? - People sometimes have their editor auto-add themselves to files even though they only deleted stuff - Or they let the editor automatically update the copyright year, because why not? - Who is the copyright holder "The coreboot project Authors"? - Or "Generated Code"? Sidestep all these issues by simply not putting these notices in individual files, let's list all copyright holders in AUTHORS instead and use the git history to deal with the rest.

The contents of vbnv in CMOS could pass the crc8 though the values could be bad. In order to fix this introduce two functions: 1. vbnv_init_cmos() 2. vbnv_cmos_failed() At the start of vboot the CMOS is queried for failure. If there is a failure indicated then the vbnv data is restored from flash backup or reset to known values when there is no flash backup.
