Completely separate DFU from application program, we now have a real bootloader.

DFU occupies 0x00100000 - 0x00100fff in flash, application starts at 0x00101000.
DFU also occupies the first couple of bytes in SRAM, application starts at 0x00200024.

In order to produce a samba-flashable image, first build dfu.bin by typing 
'make -f Makefule.dfu', succeeded by 'make TARGET=... DEBUG=... BOARD=...' and then 
concatenating the two files together, e.g. cat dfu.bin main_reqa.bin > flash.bin.

Actual flashing via DFU is still not operational, but will be implemented next
