 459  *
 460  * When the 96Board naming of a line and the schematic name of
 461  * the same line are in conflict, the 96Board specification
 462  * takes precedence, which means that the external UART on the
 463  * LSEC is named UART0 while the schematic and SoC names this
 464  * UART3. This is only for the informational lines i.e. "[FOO]",
 465  * the GPIO named lines "GPIO-A" thru "GPIO-L" are the only
 466  * ones actually used for GPIO.
