Does that not select HAVE_EARLY_POWEROFF_SUPPORT for all platforms that use ChromeEC including Intel, ARM and AMD platforms? Also not all Intel platforms that use ChromeEC need this support - only more recent ones like Brox, Fatcat and probably Brya & Rex. Other mainboards like Dedede, Volteer and prior ones don't need this since Early Sign of Life is not supported in those boards.
