		+	=== Other ECs ===
		+	ECs are supportable if you either have
		+	* interface docs for the vendor supplied closed source EC firmware or
		+	* complete docs for the EC, and docs for the hardware it should control (backlight, battery charging, power sequencing of the mainboard)
		+	* open source EC firmware
		+	Some of the info (interface docs) can be reverse engineered to some degree, but that is very tedious.
