+ help
+ 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.
