Flashrom

U can use flashrom to backup and write your flash.

Raspberry PI

Here's how to connect the Raspberry pi GPIO to the chip.

The Raspberry PI might not be able to provide enough power for the chip. Find a different 3.3v source, provide PSU-power to the laptop, desolder the chip or improvise.

You can read the flash via (asuming you have the MX25L6445):

./flashrom -p linux_spi:dev=/dev/spidev0.0 -c "MX25L6436E/MX25L6445E/MX25L6465E/MX25L6473E" -r x201-flash.bin

Do this twice and compare files to check for read errors.
