2020-11-22soc/intel/block/pmc: Move pmc_set_acpi_mode() to pmc_lib.cArthur Heymans
pmc.c mostly contains a PCI driver, while this function just calls into SMM.

This patch adds a check to avoid violating the PCH EDS recommendation that the PchPmPwrCycDur will never be smaller than the the SLP_Sx assertion widths. This code was initially added for cannonlake and now moving it to common code since the same check will be used to program the PchPmPwrCycDur for Jasperlake and Tigerlake.

2020-03-18soc: Remove copyright noticesPatrick Georgi
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.

This is a consolidation of the respective feature in `soc/intel/*lake/`, including additional support for MAINBOARD_POWER_STATE_PREVIOUS. For the latter, firmware has to keep track of the `previous` state. The feature was already advertised in Kconfig long ago, but not implemented. SoC code has to call pmc_set_power_failure_state() at least once during boot and needs to implement pmc_soc_set_afterg3_en() for the actual register write.

The newest and most useful incarnation was hiding in soc/intel/common/. We move it into the Mainboard menu and extend it with various flags to be selected to control the default and which options are visible. Also add a new `int` config MAINBOARD_POWER_FAILURE_STATE that moves the boolean to int conversion into Kconfig: 0 - S5 1 - S0 2 - previous state This patch focuses on the Kconfig code. The C code could be unified as well, e.g. starting with a common enum and safe wrapper around the get_option() call. TEST=Did what-jenkins-does with and without this commit and compared binaries. Nothing changed for the default configurations.

Instead of disabling all GPEs during PMC init in bootblock, this change moves it to pmc_fill_power_state which allows romstage to correctly fill up GPE_EN registers in chipset_power_state. This is essential for correctly identifying the wake source. Disabling all GPEs was added recently in change 74145f76 (intel/common/pmc: Disable all GPEs during pmc_init) because keeping GPEs enabled in coreboot while enabling SMI could lead to side-effects as explained in the change. Moving pmc_disable_all_gpe to pmc_fill_power_state should be safe as that happens before SMI is enabled in coreboot. TEST=Verified that GPE-based wake source is correctly identified. Also, no issues observed while resuming from S3.
