/* Important note: this memory map has the correct origins for all the flash sections.
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 */
