The bootloader implements an open standard for Device Firmware Upgrade. The 
supplied dfu-util implements the host end of the standard on linux, but in 
principle any compliant host end could be used. There is a version available 
for the Mac too.

You can also flash the freerunner using the debug board. If you want to flash 
the uBoot in NOR this is the only way to do it.
