+          However, this will confuse the currently deployed flash code which expects logical and and not
+          physical addresses and performs no sanity checks at all. If confronted with physical addresses, 
+          it will happily erase everything and brick the device. So for the time being translate these addresses
+          down in the objcopy call while updating all the flash code with proper sanity checks, then come
+          back later and fix the addresses. -- Henryk Plötz <henryk@ploetzli.ch> 2009-08-27 */
