/* 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 */
