2016-12-01romstage_handoff: remove code duplicationAaron Durbin
The same pattern was being used throughout the code base for initializing the romstage handoff structure. Provide a helper function to initialize the structure with the S3 resume state then utilize it at all the existing call sites.

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.

2016-11-12cpu/x86/mtrr: allow temporary MTRR range during corebootAaron Durbin
Certain platforms have a poorly performing SPI prefetcher so even if accessing MMIO BIOS once the fetch time can be impacted. Payload loading is one example where it can be impacted. Therefore, add the ability for a platform to reconfigure the currently running CPU's variable MTRR settings for the duration of coreboot's execution. The function mtrr_use_temp_range() is added which uses the previous MTRR solution as a basis along with a new range and type to use. A new solution is calculated with the updated settings and the original solution is put back prior to exiting coreboot into the OS or payload. Using this patch on apollolake reduced depthcharge payload loading by 75 ms.

The datasheets "Intel® Core™ Duo Processor and Intel® Core™ Solo Processor on 65 nm Process" mentions cpu C-states substates which can either be attained by adding a substate hint to the MWAIT/P_LVLx request or automatically by setting some msr bits correctly. This just sets the same msr bits as model_6fx to enable dynamic L2 cache, C2E and C4E acpi cpu states. The result is that when limiting a thinkpad x60 with a yonah T2400 cpu to the acpi cpu C2 state, the idle power usage drops from 18W to 14W. When the lowest C-state is set to C4 the idle power usage seems to remain similar.

Provide a default value of 0 in drivers/spi as there weren't default values aside from specific mainboards and arch/x86. Remove any default 0 values while noting to keep the option's default to 0.

2016-08-18Kconfig: lay groundwork for not assuming SPI flash boot deviceAaron Durbin
Almost all boards and chipsets within the codebase assume or use SPI flash as the boot device. Therefore, provide an option for the boards/chipsets which don't currently support SPI flash as the boot device. The default is to assume SPI flash is the boot device unless otherwise instructed. This falls in line with the current assumptions, but it also allows one to differentiate a platform desiring SPI flash support while it not being the actual boot device. One thing to note is that while google/daisy does boot with SPI flash part no SPI API interfaces were ever implemented. Therefore, mark that board as not having a SPI boot device.

2016-07-27cpu/x86: Support CPUs without rdmsr/wrmsr instructionsLee Leahy
Quark does not support the rdmsr and wrmsr instructions. In this case use a SOC specific routine to support the setting of the MTRRs. Migrate the code from FSP 1.1 to be x86 CPU common. Since all rdmsr/wrmsr accesses are being converted, fix the build failure for quark in lib/reg_script.c. Move the soc_msr_x routines and their depencies from romstage/mtrr.c to reg_access.c.
