2017-03-09soc/intel/skylake: Add GPIO macros for IOxAPIC and SCILi Cheng Sooi
Add two GPIO macros: 1. PAD_CFG_GPI_APIC_EDGE allows a pin to be route to the APIC with input assuming the events are edge triggered. 2. PAD_CFG_GPI_ACPI_SCI_LEVEL to route the general purpose input to SCI assuming the events are level triggered.

2017-03-08intel/skylake: Filter suspend well power failure event for Deep SxDuncan Laurie
If Deep Sx is enabled the event log will get entries added on every power sequence transition indicating that the suspend well has failed. When a board is using Deep Sx by design this is intended behavior and just fills the logs with extraneous events. To make this work the device init state has to be executed first so it actually enables the Deep Sx policies in the SOC since this code does not have any hooks back into the devicetree to read the intended setting from there. BUG=b:36042662 BRANCH=none TEST=Perform suspend/resume on Eve device with Deep S3 enabled, and then check the event log to be sure that it does not contain the "SUS Power Fail" event.

With recent change (a4b11e5c90: soc/intel/skylake: Perform CPU MP Init before FSP-S Init) to perform CPU MP init before FSP-S init, suspend resume is currently broken for all skylake/kabylake boards. All the skylake/kabylake boards store external stage cache in TSEG, which is relocated post MP-init. Thus, if FSP loading and initialization is done after MP-init, then ramstage is not able to: 1. Save FSP component in external stage cache during normal boot, and 2. Load FSP component from external stage cache during resume In order to fix this, ensure that FSP loading happens separately from FSP initialization. Add fsp_load callback for pre_mp_init which ensures that the required FSP component is loaded/saved from/to external stage cache.

2016-12-06intel PCI ops: Remove explicit PCI MMCONF accessKyösti Mälkki
MMCONF was explicitly used here to avoid races of 0xcf8/0xcfc access being non-atomic and/or need to access 4kiB of PCI config space. All these platforms now have MMCONF_SUPPORT_DEFAULT.

2016-12-06spi_flash: Make a deep copy of spi_slave structureFurquan Shaikh
Commit 36b81af (spi: Pass pointer to spi_slave structure in spi_setup_slave) changes the way spi_setup_slave handles the spi_slave structure. Instead of expecting spi controller drivers to maintain spi_slave structure in CAR_GLOBAL/data section, caller is expected to manage the spi_slave structure. This requires that spi_flash drivers maintain spi_slave structure and flash probe function needs to make a copy of the passed in spi_slave structure. This change fixes the regression on Lenovo X230 and other mainboards.

2016-12-05spi: Define and use spi_ctrlr structureFurquan Shaikh
1. Define a new structure spi_ctrlr that allows platforms to define callbacks for spi operations (claim bus, release bus, transfer). 2. Add a new member (pointer to spi_ctrlr structure) in spi_slave structure which will be initialized by call to spi_setup_slave. 3. Define spi_claim_bus, spi_release_bus and spi_xfer in spi-generic.c which will make appropriate calls to ctrlr functions.

2016-12-05spi: Pass pointer to spi_slave structure in spi_setup_slaveFurquan Shaikh
For spi_setup_slave, instead of making the platform driver return a pointer to spi_slave structure, pass in a structure pointer that can be filled in by the driver as required. This removes the need for platform drivers to maintain a slave structure in data/CAR section.

2016-11-30soc/intel/skylake: Pass proper CPU flex ratio override to FSPNaresh G Solanki
In bootblock, cpu flex ratio is set to non-turbo max. In FSP UPD, if CpuRatioOverride is zero, then it tries to program cpu ratio to zero. Since it is different than the non-zero value programmed in bootblock, FSP gives reset. To avoid the reset, set FSP UPD for CPU flex ratio override to that value as set in bootblock.

2016-11-30soc/intel/skylake: Fix top_of_ram calculationNaresh G Solanki
FSP 2.0 implementation conditionally sets PMRR base based on EnableC6Dram UPD. Therefore, handle the case of the PMRR base not being set since FSP 2.0 changed behavior from FSP 1.1 implementation. If prmrr base is non-zero value, then top_of_ram is prmrr base. If Probeless trace is enabled, then deduct trace memory size from calculated top_of_ram.

2016-11-30soc/intel/skylake: Disable Legacy PME for Root portsNaresh G Solanki
Legacy PME are enabled by default in FSP UPD region. When Legacy PME is enabled, then an SCI is generated and should be handled by OS and BIOS/Coreboot in collboration. OS requires some ACPI methods (eg _L69) which help to determine the wake source and also to clear some registers. But this infrastructure is not present as of now in coreboot and also linux handles PMEs natively. Hence the SCI was never handled by OS and the status bits were never cleared i.e., PCI_EXP_STS. For this reason the level triggered SCI will remain active and the system will wake up as soon as it enters S3. To fix this, diabled Legacy PME (PmSci for Root ports).
