2018-04-05soc/intel/skylake: Enable VT-d and X2APICNico Huber
We use the usual static addresses 0xfed90000/0xfed91000 for the GFX IOMMU and the general IOMMU respectively. These addresses have to be configured in MCHBAR registers (maybe, who knows, the blob is undocu- mented), advertised to FSP and reserved from the OS. The new devicetree option `ignore_vtd` allows to retain the old beha- viour (do whatever pre-set UPD values suggest). We also let FSP set up distinct BDFs for messages originating from the I/O-APIC and the HPET.

2017-07-01soc/intel/skylake: Remove unnecessary P-State and Flex Ratio assignmentBarnali Sarkar
This patch basically does two things - 1) Remove unnecessary setting of flex_ratio to TDP nominal: Factory configured (default) Max Non-TURBO ratio(P1) is already cofigured in MSR_PLATFORM_INFO(0xCE). If this Maximum Non-TURBO Ratio(P1) needs to be modified, it should be done using MSR_FLEX_RATIO (0x194). Here, in this code, the FLEX_RATIO is being modified by the TDP Nominal Ratio, reading the MSR_CONFIG_TDP_NOMINAL(0x648). But this value is actually less than the factory configured Maximum Non TURBO Ratio (P1). So, this code is actually not required. Also, the Bit 12 in PCH Soft Strap Register is already set in descriptor. This Bit implies Processor Boot Max Frequency - 0 = Disable Boot Max Frequency 1 = Enable Boot Max Frequency (Default) This setting determines if the processor will operate at maximum frequency at power-on and boot. Thus this patch will avoid one extra platform warm reset now onwards. 2) Remove wrongly setting Max Frequency in Bootblock phase: In the function set_max_frequency(), the P-State max ratio was set to TDP Nominal ratio if C-TDP was enabled, else it was set to Max Non Trbo ratio. But, when the cpu gets reset, it will operate with the Max-Non Turbo ratio only, which is greater than the TDP Nominal ratio. So, no need to set back the ratio to TDP Nominal which is lower than the currently operating frequency.

With the move to FSP 2.0 the number of VR types supported was reduced to 4, and the VR_RING type is no longer present. This means all existing boards using FSP 2.0 are incorrectly passing VR configuration into FSP as the values corresponding to "GT Sliced" and "GT Unsliced" have changed.

2017-02-22soc/intel/skylake: Fix broken suspend-resumeFurquan Shaikh
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.

2016-11-22spi: Clean up SPI flash driver interfaceFurquan Shaikh
RW flag was added to spi_slave structure to get around a requirement on some AMD flash controllers that need to group together all spi volatile operations (write/erase). This rw flag is not a property or attribute of the SPI slave or controller. Thus, instead of saving it in spi_slave structure, clean up the SPI flash driver interface. This allows chipsets/mainboards (that require volatile operations to be grouped) to indicate beginning and end of such grouped operations. New user APIs are added to allow users to perform probe, read, write, erase, volatile group begin and end operations. Callbacks defined in spi_flash structure are expected to be used only by the SPI flash driver. Any chipset that requires grouping of volatile operations can select the newly added Kconfig option SPI_FLASH_HAS_VOLATILE_GROUP and define callbacks for chipset_volatile_group_{begin,end}. spi_claim_bus/spi_release_bus calls have been removed from the SPI flash chip drivers which end up calling do_spi_flash_cmd since it already has required calls for claiming and releasing SPI bus before performing a read/write operation.
