Yes, if you have hardware to support this (i. e. two flash banks that
can be swapped, where the "switch" can  be  controlled  by  software,
remembers  it's state when powered off *and* has some kid of watchdog
function to toggle back to the other position in case the system does
not come up). Not many systems support this ;-)

If I don't document something, it's usually either for a good reason,
or a bad reason.  In this case it's a good reason.  :-)
