The BLE Config area needs to be subtracted from the size of the firmware. THis is because the firmware is counted by walking backwards from the end of memory, and the BLE config area is placed lower in memory than the firmware. Subtracting the BLE config size ensures the internal flash filesystem doesn't try to use the firmware as storage. Signed-off-by: Sean Cross <sean@xobs.io>
