+         Tegra's boot ROM supports a mode whereby code may be downloaded and
+         flash-programmed over a USB connection. On dev boards, this is
+         typically entered by holding down a "force recovery" button and
+         resetting the CPU. However, not all boards have such a button (one
+         example is the Compulab Trimslice), so a method to enter RCM from
+         software is useful.
+
+         Even on boards other than Trimslice, controlling this over a UART
+         may be useful, e.g. to allow simple remote control without the need
+         for mechanical button actuators, or hooking up relays/... to the
+         button.
