I've played with ideas for automatic recovery but I haven't done
anything with them yet. At least with the DS10 I have two kernels
that you can switch between with a jumper on the board.
What we can do that is cheap is to put a checksum in our rom image,
so we can catch corruption before the image is loaded. I've been
thinking about adding that in the PT_NOTE section of an elf image.
To do more we'd need a watchdog timer.
