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.

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.

2016-11-30soc/intel/skylake: Pass proper CPU flex ratio override to FSPNaresh G Solanki
In bootblock, cpu flex ratio is set to non-turbo max. In FSP UPD, if CpuRatioOverride is zero, then it tries to program cpu ratio to zero. Since it is different than the non-zero value programmed in bootblock, FSP gives reset. To avoid the reset, set FSP UPD for CPU flex ratio override to that value as set in bootblock.

2016-11-30soc/intel/skylake: Fix top_of_ram calculationNaresh G Solanki
FSP 2.0 implementation conditionally sets PMRR base based on EnableC6Dram UPD. Therefore, handle the case of the PMRR base not being set since FSP 2.0 changed behavior from FSP 1.1 implementation. If prmrr base is non-zero value, then top_of_ram is prmrr base. If Probeless trace is enabled, then deduct trace memory size from calculated top_of_ram.

2016-11-30soc/intel/skylake: Disable Legacy PME for Root portsNaresh G Solanki
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).

2016-11-30soc/intel/apollolake: Add save/restore variable MRC cacheAndrey Petrov
Apollolake MRC cache is divided into two regions: constant and variable. Currently they are clubbed together. Since variable data changes across cold reboot it triggers invalidation of the whole cache region. This change declubs the data, adds routines to load/store variable data on flash. BUG=chrome-os-partner:57515 TEST=with patch series applied: cold reboot, make sure MRC is not updated. Do S3 suspend/resume cycle.

Piggy-back on existing MRC cache infrastructure to store variable MRC data. Only one set of data can be valid at given point of time. Currently this magically happens because region alignment is forced to 0x1000 and region itself is of the same size. This needs to be somehow programmatically enforced.
