2016-12-07soc/intel/skylake: Remove unwanted spi_release callFurquan Shaikh
Skylake uses a special SPI Flash controller and does not require spi_claim_bus and spi_release_bus functionality. This was a leftover call from earlier cleanup, so remove it.

Doing PCI config operations via MMIO window by default is a requirement, if supported by the platform. This means chipset or CPU code must enable MMCONF operations early in bootblock already, or before platform-specific romstage entry. Platforms are allowed to have NO_MMCONF_SUPPORT only in the case it is actually not implemented in the silicon.

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).

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. Also move BOOTBLOCK_CONSOLE out from UART_DEBUG to CPU_SPECIFIC_OPTIONS as part of the fix needed.

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.

2016-11-10mrc: Add support for separate training cache in recovery modeFurquan Shaikh
1. Re-factor MRC cache driver to properly select RW_MRC_CACHE or RECOVERY_MRC_CACHE based on the boot mode. - If normal mode boot, use RW_MRC_CACHE, if available. - If recovery mode boot: - Retrain memory if RECOVERY_MRC_CACHE not present, or recovery is requested explicity with retrain memory request. - Use RECOVERY_MRC_CACHE otherwise. 2. Protect RW and RECOVERY mrc caches in recovery and non-recovery boot modes. Check if both are present under one unified region and protect that region as a whole. Else try protecting individual regions. 3. Update training data in appropriate cache: - Use RW_MRC_CACHE if normal mode. - Use RECOVERY_MRC_CACHE if present in recovery mode. Else use RW_MRC_CACHE. 4. Add proper debug logs to indicate which training data cache is used at any point.

chip.h has a config array PcieRpClkReqNumber which corresponds to a FSP UPD parameter, the size is currently set to 20. However the size of PcieRpClkReqNumber UPD in FSP2.0 is 24, so memcpy (config buffer to UPD buffer) in chip_fsp20.c will read beyond the bounds of config array.

This patch updates below info, [1] Delete the DPTF_CPU_ACTIVE_AC* values because these are not being used. Hence, removing unnecessary defines. [2] Add new DPTF_TSR0_ACTIVE_AC* temperature trip points for TSR0 external thermal sensor. These trip points are being used by _ACx methods to control the fan speed on Skylake-U fan based Lars and Kunimitsu platforms. [3] Follow up patches are using DPTF_CPU_ACTIVE_AC* temperature trip points in board specific acpi/dptf.asl (for lars, kunimitsu, etc) to control the fan speed as per the CPU temperature trip points. [4] Newly added _ACx methods for thermal sensor TSR0 in this patch has nothing to do with DPTF_CPU_ACTIVE_AC*. We can control fan speed using various different thermal sensors.
