I don't use embedded arm, but on other microcontrollers, bootloaders are
often also at the end of the flash. The main reason for this is to avoid
having to modify the linker file for normal programs (to switch between
bootloadable and not). For that, you need to have the exact amount of flash
in your CPU profile.
