+	  The AM335x SoC has a total of 6 UARTs (UART0 to UART5 as referenced
+	  in documentation, etc) available to it.  Depending on your specific
+	  board you may want something other than UART0 as for example the IDK

+	  The BAV335x has various version of the board. Rev.A (mostly obsolete)
+	  used 10/100 Ethernet PHY while Rev.B uses a Gigabit Ethernet PHY.
