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. BUG=None BRANCH=None TEST=Compiles successfully.

2016-11-20intel sandy/ivy: Improve DIMM replacement detectionKyösti Mälkki
When MRC cache is available, first read only the SPD unique identifier bytes required to detect possible DIMM replacement. As this is 11 vs 256 bytes with slow SMBus operations, we save about 70ms for every installed DIMM on normal boot path. In the DIMM replacement case this adds some 10ms per installed DIMM as some SPD gets read twice, but we are on slow RAM training boot path anyways.

2016-11-20intel sandy/ivy: Skip SPD loading on S3 resume pathKyösti Mälkki
For S3 resume path SPD is only used for DIMM replacement detection. As this detection already fails in the case of removal/insertion of same DIMM, we can rely on cbmem_recovery() failure alone to force system reset in case someone accidentally does DIMM replacements while system is suspend-to-ram stage. Skipping DIMM replacement detection allows skipping slow SPD loading, thus reducing S3 resume path time by 80ms for every installed DIMM.

2016-10-29nb/intel/sandybridge/gma: Always initialize DP buffer translationNico Huber
These settings should be always made by the firmware, no matter if we set up graphics or not. It looks like Linux doesn't even know these registers. The values are taken from the PRMs for Sandy Bridge and Ivy Bridge [1, 2]. They match the settings that were done in the native graphics path for Ivy Bridge. I expect the differences to be an update (i.e. the set- tings we did on the Sandy Bridge path were just outdated). Also, these settings affect the PCH and not the CPU which are independent from each other.

Previously the 945gc raminit only worked for 533MHz FSB CPUs. This extends the tRD_Mclks in drt0_table for other FSB speeds. The values are taken from the vendor bios of Gigabyte ga-945gcm-s2l.
