* zpu-loader is a simple program created for White Rabbit PTP Core(WRPC).
* It loads the zpu firmware, given as the argument, directly to a dual-port RAM,
* which is the part of WRPC. This way, there is no need to synthesize whole
* FPGA project if one change anything in ZPU firmware.
* The binary file taken by zpu-loader is the result of the following action:
*
* ${CC} -o $(OUTPUT).elf $(OBJS) $(LDFLAGS)
* ${OBJCOPY} -O binary $(OUTPUT).elf $(OUTPUT).bin
*
* zpu-loader uses rawrabbit kernel driver written by Alessandro Rubini.
