		/*
		* Legend: proper name = the GPIO line is used as GPIO
		* NC = not connected (not routed from the SoC)
		* "[PER]" = pin is muxed for peripheral (not GPIO)
		* "" = no idea, schematic doesn't say, could be
		* unrouted (not connected to any external pin)
		* LSEC = Low Speed External Connector
		* HSEC = High Speed External Connector
		*
		* Pin assignments taken from LeMaker and CircuitCo Schematics
		* Rev A1.
		*
		* For the lines routed to the external connectors the
		* lines are named after the 96Boards CE Specification 1.0,
		* Appendix "Expansion Connector Signal Description".
		*
		* When the 96Board naming of a line and the schematic name of
		* the same line are in conflict, the 96Board specification
		* takes precedence, which means that the external UART on the
		* LSEC is named UART0 while the schematic and SoC names this
		* UART2. This is only for the informational lines i.e. "[FOO]",
		* the GPIO named lines "GPIO-A" thru "GPIO-L" are the only
		* ones actually used for GPIO.
