2017-07-17soc/intel/common/gpio: distingiush single vs multi acpi devicesAaron Durbin
Sadly, small core and big core are not aligned with the OS driver's expectation on the number of ACPI devices used for each community. Big core uses a single device while small cores use one ACPI device per community. Allow for this distinction within the common gpio implementation and ensure apollolake is utilizing the new option to retain the correct behavior.

2017-06-20soc/intel/common: Add SMM common code for Intel PlatformsBrandon Breitenstein
SMI code is very similar across Intel platforms. Move this code to common/block/smi to allow it to be shared between platforms instead of duplicating the code for each platform. smihandler.h has already been made common so all it will contain is name changes and a move to the common block location. Due to moving smihandler code, APL changes are bundled here to show this change.

2017-04-28soc/intel/apollolake: Update default LPDDR4 CA ODT configRavi Sarawadi
Update default ODT config to have correct CA ODT settings as the current defaults are incorrect for all the current apollolake designs. All the current designs pull both A and B channels' LPDDR4 modules' ODT pins to 1.1V. Therefore, the correct impedance setting needs to be applied. In order for the settings to take effect one needs to clear the memory training cache in deployed systems. Trigger this by bumping the memory setting version for the SoC. If needed in the future support for allowing the override of this setting from the mainboard should be straight forward. It's just not necessary at this time.

Also taking this opportunity to namespace all VBOOT Kconfig options, and clean up menuconfig visibility for them (i.e. some options were visible even though they were tied to the hardware while others were invisible even though it might make sense to change them).

2017-03-28vboot: Assume EC_SOFTWARE_SYNC and VIRTUAL_DEV_SWITCH by defaultJulius Werner
The virtualized developer switch was invented five years ago and has been used on every vboot system ever since. We shouldn't need to specify it again and again for every new board. This patch flips the Kconfig logic around and replaces CONFIG_VIRTUAL_DEV_SWITCH with CONFIG_PHYSICAL_DEV_SWITCH, so that only a few ancient boards need to set it and it fits better with CONFIG_PHYSICAL_REC_SWITCH. (Also set the latter for Lumpy which seems to have been omitted incorrectly, and hide it from menuconfig since it's a hardware parameter that shouldn't be configurable.) Since almost all our developer switches are virtual, it doesn't make sense for every board to pass a non-existent or non-functional developer mode switch in the coreboot tables, so let's get rid of that. It's also dangerously confusing for many boards to define a get_developer_mode() function that reads an actual pin (often from a debug header) which will not be honored by coreboot because CONFIG_PHYSICAL_DEV_SWITCH isn't set. Therefore, this patch removes all those non-functional instances of that function. In the future, either the board has a physical dev switch and must define it, or it doesn't and must not. In a similar sense (and since I'm touching so many board configs anyway), it's annoying that we have to keep selecting EC_SOFTWARE_SYNC. Instead, it should just be assumed by default whenever a Chrome EC is present in the system. This way, it can also still be overridden by menuconfig.

Wake status is calculated from the four pairs of gpe0 in cbmem CBMEM_ID_POWER_STATE which is filled very early in romstage and depends on the routing information in PMC GPE_CFG register. Coreboot sets the proper value of routing based on devicetree from pmc_init.
