In the interest of making long-term branch maintenance incur as little technical debt on us as possible, we should not maintain any files on the branch we are not actually using. This has the added effect of making it extremely clear when merging CLs from the main branch when changes have the possibility to affect us. The follow-on CL adds a convenience script to actually pull updates from the main branch and generate a CL for the update.

- help
- Select MKBP delivery method
-
-config PLATFORM_EC_MKBP_USE_GPIO
- bool "Use GPIO"
- help
- Select to send MKBP events via GPIO. You should define GPIO_EC_INT_L
- in gpio_map.h as output from the EC. The GPIO is used to indicate an
- event is ready for serving by the AP.

-config PLATFORM_EC_MKBP_USE_GPIO_AND_HOST_EVENT
- bool "Use GPIO and host event"
- help
- MKBP events are notified by using both a GPIO and a host event.
-
- You should use this if you are using a GPIO to notify the AP of an MKBP
- event, and you need an MKBP event to wake the AP in suspend and the
- AP cannot wake from the GPIO. Since you are using both a GPIO and
- a hostevent for the notification, make sure that the S0 hostevent mask
- does NOT include MKBP events. Otherwise, you will have multiple
- consumers for a single event. However, make sure to configure the
- host event *sleep* mask in coreboot to include MKBP events. In order to
- prevent all MKBP events from waking the AP, use
- CONFIG_MKBP_EVENT_WAKEUP_MASK to filter the events.
-
-config PLATFORM_EC_MKBP_USE_CUSTOM
- bool "Use custom method"
- help
- Select to send MKBP events using custom method. You need to define
- mkbp_set_host_active_via_custom() which is called when there's a MKBP event
- to be sent. for more about the function, refer to mkbp_event.h.
