* hammer: Add magnemite boardNicolas Boichat2019-08-161-1/+7

* hammer: Refactor config options to support more variantsNicolas Boichat2019-08-121-1/+1
| | | | | | | | | | | | | | | | | board.h is already quite difficult to read, and will become worse as we add more and more derivatives, let's refactor most of the variations into variants.h.

* ec.tasklist: Consolidate duplicate commentsDaisuke Nojiri2019-04-081-11/+1
| | | | | | | | | | | | | | | | | | | | | | | It's simply a bad idea to describe a macro in multiple locations. It'll make it hard to change. It'll be difficult to keep all locations in sync. This patch replaces the comment duplicated in all ec.tasklist with a pointer to the CONFIG_TASK_LIST definition. The macro will be described in a single place (just like all/most other macros).

| | | | | | | | | | | | | | | | | | Change the names to generic touchpad_* functions, instead of vendor-specific names. Makes it a little easier to add drivers for other touchpads. Also fix console_channel.inc to add the channel whenever any touchpad is used.
