 * J2002 63453-140LF.
 *
 * For the lines routed to the external connectors the

 *
 * 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
 * UART3. This is only for the informational lines i.e. "[FOO]",
 * the GPIO named lines "GPIO-A" thru "GPIO-L" are the only
