The serial_transfer loader, as long as the target program voluntarily terminates itself at some point, is able to load multiple programs consecutively without requiring a physical power cycle to reload the transfer program from CD. The current example.mk juggles between two different "memory layouts", one for "burn to a physical CD" and another for "load via serial cable". Because the serial_transfer program now relocates itself to the end of system memory, this means the 0x8c010000 area is now usable by programs that are loaded by serial_transfer.
