Switch to using the common MEC interface instead of the Chrome EC specific code. Tested on a Chell chromebook that has a MEC based Chrome EC to ensure that the EC interface is still functional.

2018-05-24chromeec: Add support for controlling USB port powerEmil Lundmark
This maps a bit field to the EC (EC_ACPI_MEM_USB_PORT_POWER) that can be used to control the power state of up to 8 individual USB ports. Some Chromeboxes have their GPIO pins for controlling USB port power wired to the EC, so they cannot be accessed directly by coreboot.

2017-03-28vboot: Move remaining features out of vendorcode/google/chromeosJulius Werner
This patch attempts to finish the separation between CONFIG_VBOOT and CONFIG_CHROMEOS by moving the remaining options and code (including image generation code for things like FWID and GBB flags, which are intrinsic to vboot itself) from src/vendorcode/google/chromeos to src/vboot. 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).

2016-11-18google/chromeec: Add common infrastructure for boot-mode switchesFurquan Shaikh
Instead of defining the same functions for reading/clearing boot-mode switches from EC in every mainboard, add a common infrastructure to enable common functions for handling boot-mode switches if GOOGLE_CHROMEEC is being used. Only boards that were not moved to this new infrastructure are those that do not use GOOGLE_CHROMEEC or which rely on some mainboard specific mechanism for reading boot-mode switches.

2016-10-02Kconfig: Update default hex values to start with 0xMartin Roth
Kconfig hex values don't need to be in quotes, and should start with '0x'. If the default value isn't set this way, Kconfig will add the 0x to the start, and the entry can be added unnecessarily to the defconfig since it's "different" than what was set by the default. A check for this has been added to the Kconfig lint tool.

2016-08-04chromeec: Chrome EC firmware source selection for EC and PD firmwaresPaul Kocialkowski
In some cases, we don't want the Chrome EC firmwares (both EC and PD) built directly by the coreboot build system or included in images at all. This is already supported with EC_EXTERNAL_FIRMWARE but it does implement a binary (build and include) or (neither build nor include) policy. Some cases require the ability to separately control whether the EC and PD firmwares should be built and included by the coreboot build system, only included from externally-built images or not included at all. This introduces config changes implementing that behaviour, renaming options to make it clear that they are specific to the Chrome EC.
