2017-02-17nb/intel/x4x: Implement resume from S3 suspendArthur Heymans
It rewrites the results of receive enable stored in the upper nvram region, to avoid running receive enable again. Some debug info is also printed about the self-refresh registers. (Not enforcing a reset here, since 0 does not necessarily mean it's not in self-refresh).

2017-02-17nb/intel/x4x: Fix raminit on reset pathArthur Heymans
Previously the raminit failed on hot reset and to work around this issue it unconditionally did a cold reset. This has the following issues: * it's slow; * when the OS issues a hot reset some disk drives expect their 5V power supply to remain on, which gets cut off by a cold reset, causing data corruption. To fix this some steps in raminit must be ommited on the reset path. This includes receive enable calibration. To achieve this it stores receive enable results in RTC nvram for them to be rewritten on the resume path. Note: The same thing needs to be done on the S3 resume path. Calling a hot reset after raminit "outb(0x6, 0cf9)" works.

2017-02-04drivers/intel/gma/vbt: Add Kconfig symbol for SSC refNico Huber
The selection of the SSC reference frequency for LVDS was based on a completely unrelated clock. The `ssc_freq` flag should be set when the SSC reference runs at a different frequency than the general display reference clock (DREF). 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.

A fix is to hardcode the core display and render clocks to their maximum, potentially also improving graphical performance. Vendor bios on all boards in coreboot with this northbridge have the same value in this PCI config address.

DIMMs are counted from 0 to 3 where 0..1 covers channel 0, and 2..3 covers channel 1. Since we have two DIMMs per channel, we have to multiply the channel index by 2 (or shift it left by 1) to get the index of the first DIMM in the channel. Finally, to get the offset of a DIMM in the channel we take its index modulo 2 (again, the number of DIMMs per channel).

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.
