			With newer versions of Raspian it seems to be necessary to specify the SPI speed (in kHz), e.g.
			'''flashrom -p linux_spi:dev=/dev/spidev0.0,spispeed=16000'''

			Be aware that '''spispeed=16M''' sets the speed to 16kHz, as the postfix seems to be removed silently!

			In case your notebook has two SPI flashs it may be necessary to connect CS# pin of the other flash to 3.3V from the RaspberryPi.
