-	  Support NS16550 UART or compatible with driver model. This can be
-	  enabled in the device tree with the correct input clock frequency.
-	  If the input clock frequency is not defined in the device tree,
-	  the macro CONFIG_SYS_NS16550_CLK defined in a legacy board header
-	  file will be used. It can be a constant or a function to get clock,
-	  eg, get_serial_clock().
