ec/lenovo/h8: Reintroduce h8_mb_init() for specific boards
Mainboard specific dock-init mechanism introduced https://review.coreboot.org/c/coreboot/+/36093 works on most boards, but https://ticket.coreboot.org/issues/256 shows that some boards (e.g. x201 and t410) need communication with h8 EC to enable or disable dock, (in dock_connect() and dock_disconnect() respectively) so they must be done after the h8 EC is brought up, which is not garanteed in the above mainboard specific dock-init mechanism. This time, a hook function h8_mb_init() will be called at the end of h8_enable(). (in place of the ancient h8_mainboard_init_dock() removed in CB:36093) Its default implementation is a weak empty function, but could be overrided with a strong one for boards needing to perform actions which should be done after h8 EC is brought up. This should fix the regression detected in https://ticket.coreboot.org/issues/256 Change-Id: I3674fbfeab2ea2cd2a4453a8e77521157d553388 Signed-off-by: Bill XIE <persmule@hardenedlinux.org> Reviewed-on: https://review.coreboot.org/c/coreboot/+/39708 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Patrick Rudolph <siro@das-labor.org>
