in fact, it's up to you :
You can either have your nk.bin file get copied as is in flash, then
expanded in RAM by bootloader, and have it executed in RAM. In this case,
the process of loading from flash to RAM is the same as loading from
ethernet to RAM, except that you would take datas from flash instead of
ethernet.

You can also have your nk.nb0 located direcly in flash, and then, if your
flash allows code execution (as an example, NOR flash), have it directly
executed from flash, either through a jump from bloader, or even without a
bloader at all (if the flash is the boot flash).
