2017-11-22chromeec: Change the API for hostevent/wake masks to handle 64-bitFurquan Shaikh
ChromeEC is getting ready to bump up the hostevents and wake masks to 64-bits. The current commands to program hostevents/wake masks will still operate on 32-bits only. A new EC host command will be added to handle 64-bit hostevents/wake masks. In order to prevent individual callers in coreboot from worrying about 32-bit/64-bit, the same API provided by google/chromeec will be updated to accept 64-bit parameters and return 64-bit values. Internally, host command handlers will take care of masking these parameters/return values to appropriate 32-bit/64-bit values.

2017-07-01ec/google/chromeec: Add support for EC device eventsDuncan Laurie
Add support for the new EC device event interface which is used to report events from devices that are connected behind the EC. This can be used to differentiate wake sources from the EC in the case that the EC has the wake pins from various devices. This can be used in case the AP is unable to directly wake from the device itself, for example when using the Deep S3 state on Intel platforms only a few pins can directly wake the AP. BUG=b:30624430 TEST=build google/* boards that use chrome EC. Feature is used and tested further in a subsequent commit.

2016-07-15ec/google/chromeec: provide common SMI handler helpersAaron Durbin
The mainboards which use the Chrome EC duplicate the same logic in the mainboard smi handler. Provide common helper functions for those boards to utilize.
