   5            However, this will confuse the currently deployed flash code which expects logical and and not
   6            physical addresses and performs no sanity checks at all. If confronted with physical addresses,
   7            it will happily erase everything and brick the device. So for the time being pretend these addresses
   8            to start at 0x0 while updating all the flash code with proper sanity checks, then come back later and
   9            fix the addresses. -- Henryk Plötz <henryk@ploetzli.ch> 2009-08-27 */
