# The test setup enables RDP level 1 by enabling hardware write protect and then
# enabling software write protect (with reboot of the EC); the test setup then
# disables hardware write protect, so that we can perform reads and change RDP
# levels through the bootloader (only accessible when HW write protect is
# disabled).
#
# When the test script starts, a read through the bootloader is done without
# disabling flash protection (changing RDP state). We verify that we are unable
# to read any data.
#
# Next a read through the bootloader is done, while also disabling flash
# protection (changing to RDP level 0), which triggers a mass erase. We verify
# that the bytes in the output are all 0xFF and that the firmware is no longer
# functional.
