2017-03-10soc/intel/skylake:Add _DSM method to reduce D3 cold delay for eMMC controllersowmyav
eMMC Controller is taking over 100ms to resume during runtime which results in I/O latency issues on the Skylake systems like Cave and Caroline. This patch adds _DSM method for eMMC comtroller for specifying the device readiness durations. Function index 9 returns package of five integers to set D3 cold delay to zero and ACPI constant Ones for the elements where overriding the default values is not desired. BUG=b:35774937 BRANCH=none TEST=update caroline coreboot and test i/o latency is under 100ms Change-Id: Iacc8aa8560897da8770fe559ca8cd17aaf6ebeba Signed-off-by: Sowmya V <v.sowmya@intel.com> Reviewed-on: https://review.coreboot.org/18532 Tested-by: build bot (Jenkins) Reviewed-by: Duncan Laurie <dlaurie@chromium.org>

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.

2016-12-06spi_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.

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).

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.

2016-10-16soc/intel/skylake: Implement Global Reset MEI messageSubrata Banik
As per ME BWG, there are two mechanism to generate a Global Reset (resets both host and Intel ME), one is through CF9h IO write of 6h or Eh with "CF9h Global Reset" (CF9GR) bit set, PMC PCI offset ACh[20]. Another is to issue the Global Reset MEI message. Because any attempts to cause global reset without synchronizing the two sides might cause unwanted side effects, such as unwritten flash data that will get destroyed if the host were to cause a global reset without informing Intel ME firmware, the recommended method is to send a Global Reset MEI message when the following conditions are met: The PCH chipset firmware just needs to complete the Intel ME Interface #1 initialization and check the Intel ME HFSTS state if Intel ME is not in ERROR state and is accepting MEI commands then firmware should be able to use Global Reset MEI message to trigger global reset. Furthermore, if Intel ME is in ERROR state, BIOS can use I/O 0xCF9 write of 0x06 or 0x0E command with PCH ETR3 register bit [20] to perform the global reset.
