Hello Felix Singer, Lance Zhao, build bot (Jenkins), Furquan Shaikh, Tim Wawrzynczak, Tim Wawrzynczak, Paul Menzel, Angel Pons, Subrata Banik, Patrick Rudolph,
I'd like you to reexamine a change. Please visit

to look at the new patch set (#14).
Change subject: soc/intel/pmc: add a note about legacy OSes/payloads to PM Timer Kconfig ......................................................................
soc/intel/pmc: add a note about legacy OSes/payloads to PM Timer Kconfig
Since ACPI 5.0A it is allowed to disable the ACPI Timer, when the according FADT flag `ACPI_FADT_PLATFORM_CLOCK` is unset.
Starting with Skylake, most platforms (except Xeon-SP) support PM Timer emulation, so even legacy OSes and payloads should work fine with the hardware PM Timer disabled. However, when the `TMR_STS` functionality is required, some legacy OSes might still not work (properly).
Add a note about this to the Kconfig help.
