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. BUG=chrome-os-partner:63114 BRANCH=None TEST=Verified that 100 cycles of suspend/resume worked fine on poppy.

2017-02-20lynxpoint/broadwell: fix PCH power optimizerMatt DeVillier
Setting both bits 27 and 7 of PCH register PMSYNC_CFG (PMSYNC Configuration; offset 0x33c8) causes pre-OS display init to fail on HSW-U/Lynxpoint and BDW-U ChromeOS devices when the VBIOS/GOP driver is run after the register is set. A re-examination of Intel's reference code reveals that bit 7 should be set for the LP PCH, and bit 27 for non-LP, but not both simultaneously. The previous workaround was to disable the entire power optimizer section via a Kconfig option, which isn't ideal. Test: unset bit 27 of PMSYNC_CFG and boot google/lulu, observe functional pre-OS video output Change-Id: I446e169d23dd446710a1648f0a9b9599568b80aa Signed-off-by: Matt DeVillier <matt.devillier@gmail.com> Reviewed-on: https://review.coreboot.org/18385 Tested-by: build bot (Jenkins) Reviewed-by: Martin Roth <martinroth@google.com> Reviewed-by: Duncan Laurie <dlaurie@chromium.org>

2017-01-13fsp_baytrail: Enable graphic init per defaultWerner Zeh
Baytrail SoC has a bug where in some cases the DisplayPort can hang leading to a non-working display (it just stays black). To avoid this hang, a patch was introduced in 02/2016 (1c3b1112fa - fsp_baytrail: Fix a possible hanging DisplayPort) but per default not switched on so that each mainboard can decide if it wants to use this patch or not. Recently a new case of this bug was reported by Benoit Sansoni (benoit.sansoni@kontron.com) and he requested to enable this fix per default as it costs him a lot of time to find the cause and even the already available fix in coreboot. To avoid this effort for someone else in the future we can enable this fix per default as no negative side effects are known and it is now tested at Siemens and at Kontron on different mainboards with success. As the goal is to enable this code permanently the config switch is not longer needed and is removed.

2016-12-23spi: Get rid of SPI_ATOMIC_SEQUENCINGFurquan Shaikh
SPI_ATOMIC_SEQUENCING was added to accomodate spi flash controllers with the ability to perform tx and rx of flash command and response at the same time. Instead of introducing this notion at SPI flash driver layer, clean up the interface to SPI used by flash. Flash uses a command-response kind of communication. Thus, even though SPI is duplex, flash command needs to be sent out on SPI bus and then flash response should be received on the bus. Some specialized x86 flash controllers are capable of handling command and response in a single transaction. In order to support all the varied cases: 1. Add spi_xfer_vector that takes as input a vector of SPI operations and calls back into SPI controller driver to process these operations. 2. In order to accomodate flash command-response model, use two vectors while calling into spi_xfer_vector -- one with dout set to non-NULL(command) and other with din set to non-NULL(response). 3. For specialized SPI flash controllers combine two successive vectors if the transactions look like a command-response pair. 4. Provide helper functions for common cases like supporting only 2 vectors at a time, supporting n vectors at a time, default vector operation to cycle through all SPI op vectors one by one.

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).

2016-11-30soc/intel/apollolake: Add save/restore variable MRC cacheAndrey Petrov
Apollolake MRC cache is divided into two regions: constant and variable. Currently they are clubbed together. Since variable data changes across cold reboot it triggers invalidation of the whole cache region. This change declubs the data, adds routines to load/store variable data on flash. BUG=chrome-os-partner:57515 TEST=with patch series applied: cold reboot, make sure MRC is not updated. Do S3 suspend/resume cycle.

Piggy-back on existing MRC cache infrastructure to store variable MRC data. Only one set of data can be valid at given point of time.

Current implementation checks for CONFIG_BOOTBLOCK_CONSOLE and then initializes UART. If only CONFIG_BOOTBLOCK_CONSOLE is enabled without enabling CONFIG_UART_DEBUG, there are compilation issues. This is the case when using SIO UART for Skylake DT platform. Hence initialize UART when CONFIG_UART_DEBUG is enabled and not based on CONFIG_BOOTBLOCK_CONSOLE.

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.
