2018-01-11intel/fsp2_0: Set boot mode default as per s3wake statusAamir Bohra
Currently bootmode default is set to FSP_BOOT_WITH_FULL_CONFIGURATION and bootmode UPD is updated in fsp_fill_mrc_cache based on mrc cache data validity. With current implementation in S3 resume path, if mrc cache data is invalid, the bootmode is not updated further and remains set at FSP_BOOT_WITH_FULL_CONFIGURATION. This results in fsp-m to get incorrect boot mode context and reinitialize memory in S3 resume path. In correct flow fspm should have correct bootmode context i.e. S3 resume and return error in case mrc cache data is invalid or not found.

2018-01-11intel/fsp2_0: Issue hard reset in S3 resume for invalid mrc cache dataAamir Bohra
In S3 resume, for cases if valid mrc cache data is not found or RECOVERY_MRC_CACHE hash verification fails, the S3 data pointer would be null and bootmode is set to BOOT_WITH_FULL_CONFIGURATION. This gets memory to be retrained in S3 flow. Data context including that of imdr root pointer would be lost, invoking a hard reset in romstage post memory init.

2017-10-23drv/intel/gma/opregion: fix opregion version for WindowsMatt DeVillier
Although Intel's current spec[1] shows the OpRegion structure version as being the top 16 bits of the field, Intel's Windows drivers require the OpRegion structure version to be in the top 8 bits of the field when not using a VGA BIOS (eg, NGI or GOP driver). As the Linux i915 driver only checks that the version is >= 2, there is no change in functionality there. This change effectively matches Intel's implementation in TianoCore, where the version is set to 0x0200 << 16.

This patch removes checks that ensure EC to be in RO for recovery boot. We do not need these checks because when recovery is requested automatically (as opposed to manually), we show 'broken' screen where users can only reboot the device or request recovery manually. If recovery is requested, Depthcharge will check whether EC is in RO or not and recovery switch was pressed or not. If it's a legitimate manual recovery, EC should be in RO. Thus, we can trust the recovery button state it reports. This patch removes all calls to google_chromeec_check_ec_image, which is called to avoid duplicate memory training when recovery is requested but EC is in RW.

The caller of find_fsp() only takes care about a NULL-pointer but not about a possible error code. This leads to memory access violations in case of error when FspTempRamInit is called.

On Chrome OS systems a memory setting change is needed to be deployed without updating the FSP blob proper. Under such conditions one needs to trigger retrain of the memory. For ease of use provide an option, FSP_PLATFORM_MEMORY_SETTINGS_VERSIONS, which incorproates the SoC and mainboard memory setting version number into the FSP version passed to the platform. The lower 8 bits of the FSP version are the build number which in practice is normally 0. Use those 8 bits to include the SoC and mainboard memory settings version. When FSP, SoC, or mainboard memory setting number is bumped a retrain will be triggered.

Some renamings force us to update our code: * Scan_Ports() moved into a new package Display_Probing. * Ports Digital[123] are called HDMI[123] now (finally!). * `Configs_Type` became `Pipe_Configs`, `Config_Index` `Pipe_Index`. Other noteworthy changes in libgfxinit: * libgfxinit now knows about ports that share pins (e.g. HDMI1 and DP1) and refuses to enable any of them if both are connected (which is physically possible on certain ThinkPad docks). * Major refactoring of the high-level GMA code.

2017-03-28Remove libverstage as separate library and source file classJulius Werner
In builds without CONFIG_VBOOT_SEPARATE_VERSTAGE, verstage files are linked directly into the bootblock or the romstage. However, they're still compiled with a separate "libverstage" source file class, linked into an intermediate library and then linked into the final destination stage. There is no obvious benefit to doing it this way and it's unclear why it was chosen in the first place... there are, however, obvious disadvantages: it can result in code that is used by both libverstage and the host stage to occur twice in the output binary. It also means that libverstage files have their separate compiler flags that are not necessarily aligned with the host stage, which can lead to weird effects like <rules.h> macros not being set the way you would expect. In fact, VBOOT_STARTS_IN_ROMSTAGE configurations are currently broken on x86 because their libverstage code that gets compiled into the romstage sets ENV_VERSTAGE, but CAR migration code expects all ENV_VERSTAGE code to run pre-migration. This patch resolves these problems by removing the separate library. There is no more difference between the 'verstage' and 'libverstage' classes, and the source files added to them are just treated the same way a bootblock or romstage source files in configurations where the verstage is linked into either of these respective stages (allowing for the normal object code deduplication and causing those files to be compiled with the same flags as the host stage's files). Tested this whole series by booting a Kevin, an Elm (both with and without SEPARATE_VERSTAGE) and a Falco in normal and recovery mode.

2017-03-18nb/i945/gma.c: Refactor panel setupArthur Heymans
This reuses some of gm45 code to set up the panel. Panel start and stop delays and pwm frequency can now be set in devicetree. Linux does not make the difference between 945gm and gm45 for panel delays, so it is safe to assume the semantics of those registers are the same. The core display clock is computed according to "Mobile Intel® 945 Express Chipset Family" Datasheet. This selects Legacy backlight mode since most targets have some smm code that rely on this. This sets the same backlight frequency as vendor bios on Thinkpad X60 and T60. A default of 180Hz is selected for the PWM frequency if it is not defined in the devicetree, this might be annoying for displays that are LED backlit, but is a safe value for CCFL backlit displays.

For most platforms, there is no choice, i.e. for i945 and gm45 the SSC reference always differs from the display reference clock (i945: 66Mhz SSC vs. 48MHz DREF; gm45: 100MHz SSC vs. 96Mhz DREF), for Nehalem and newer, it's the same frequency for SSC/non-SSC (120MHz). The only, currently supported platform with a choice seems to be Pineview, where the alternative is 100MHz vs. the default 96MHz.

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.
