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 translate these addresses
8 down in the objcopy call while updating all the flash code with proper sanity checks, then come
9 back later and fix the addresses. -- Henryk Plötz <henryk@ploetzli.ch> 2009-08-27 */
