RedBoot is normally the name of the image running directly from ROM/Flash.
Redboot[backup] is normally the name of an image to be loaded into RAM and
run from there. We should probably change those names really - they're
quite misleading.
Not very surprisingly if you think about it, you can't update the Flash
image ("RedBoot") if you are running from it at the time - your code will
instantly have moved around!
NB this isn't always the case - on some platforms "RedBoot" is a ROMRAM
startup type application, in which case you can update it, and there's no
need for a RedBoot[backup] image.
