2018-11-08soc/intel/common: Add option to disable eSPI SMI at runtimeDuncan Laurie
Add an option that will disable eSPI SMI when ACPI mode is enabled, and re-enable eSPI SMI when ACPI mode is disabled. Additionally it ensures eSPI SMI is disabled on the ACPI OS resume path. This allows a mainboard to ensure that the Embedded Controller will not be able to assert SMI at runtime when booted into an ACPI aware operating system. This was tested on a Sarien board with the Wilco EC to ensure that the eSPI SMI enable bit is clear when booted into the OS, and remains clear after resume.

2018-10-08Move compiler.h to commonlibNico Huber
Its spreading copies got out of sync. And as it is not a standard header but used in commonlib code, it belongs into commonlib. While we are at it, always include it via GCC's `-include` switch. Some Windows and BSD quirk handling went into the util copies. We always guard from redefinitions now to prevent further issues.

2018-06-28soc/intel/common: Disable GPEs just before enabling SMIsFurquan Shaikh
Call to pmc_disable_all_gpe is required before enabling SMIs to ensure that we do not end up in a recursive SMI handler loop as mentioned in change 74145f7 (intel/common/pmc: Disable all GPEs during pmc_init). Thus, this call was added at the end of pmc_fill_power_state as we want to ensure that all the GPE registers are backed up before being cleared for identifying the wake source in ramstage. This resulted in a side-effect on APL where pmc_fixup_power_state was called much later in the boot process. Even though we have got rid of pmc_fixup_power_state, this change moves the call to pmc_disable_all_gpe to happen just before enabling SMIs. This helps to keep the disabling of GPEs logically before the enabling of SMIs and any clean ups that happen in pmc or soc-specific code should not affect the state of GPEs. BUG=b:110836465 TEST=Verified that wake sources are correctly identified on KBL and APL. Also, no SMI handler issues observed when resuming.

2018-03-05soc/intel/common/block/smm: Add configurable delay before entering S5Furquan Shaikh
This change adds a configurable delay in milliseconds before SLP_EN is set in SLP_SMI for S5. Reason for doing this is to avoid race between SLP and power button SMIs. On some platforms (Nami, Nautilus), it was observed that power button SMI triggered by EC was competing with the SLP SMI triggered by keyboard driver. Keyboard driver indicated power button press which resulted in depthcharge triggering SLP_SMI, causing the AP to enter S5. However, the power button press also causes the EC to send a pulse on PWRBTN# line, which is debounced for 16ms before an interrupt is triggered. This interrupt was generated after SLP_SMI is processed which resulted in the device waking back up from S5. This change adds a config option SOC_INTEL_COMMON_BLOCK_SMM_S5_DELAY_MS which is used to add a delay before SLP_EN is set for S5. This change should only affect CHROMEOS boards as the config option will be 0 in other cases. BUG=b:74083107 TEST=Verified that nami, nautilus do not wake back from S5 on power button press at dev mode screen.
