+================
+
+Up to two PSCs can be used as console.
+
+Support for hardware handshake has not been implemented yet.
+
+*) The first (default) console port is defined by:
+ #define CONFIG_PSC_CONSOLE <PSC number>
+
+*) The second (alternative) console port is defined by:
+ #define CONFIG_PSC_CONSOLE2 <PSC number>
+
+*) Commands to switch to the second console:
+ setenv stdout serial1
+ setenv stderr serial1
+ setenv stdin serial1
+
+*) Commands to switch to the first console:
+ setenv stdout serial0
+ setenv stderr serial0
+ setenv stdin serial0
+
+*) If a file descriptor is set to "serial" then the
+ current serial device will be used.
