2016-12-15soc/intel/common: provide option to invalide MRC cache on recoveryAaron Durbin
Allow a board/platform to invalidate the normal MRC cache when hardware retraining is requested in recovery mode. A small 4 byte payload is used to update the latest data written. It will of course fail on MRC cache retreival on next usage.

2016-12-15soc/intel/common: remove mrc cache assumptionsAaron Durbin
Update the mrc cache implementation to use region_file. Instead of relying on memory-mapped access and pointer arithmetic use the region_devices and region_file to obtain the latest data associated with the region. This removes the need for the nvm wrapper as the region_devices can be used directly. Thus, the library is more generic and can be extended to work on different boot mediums.

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.

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).

2016-11-22spi: 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.
