-# This script monitors S0/S1 fault GPIO and detects errors or warnings from CPUs
-#
-# According to OpenBMC_Software_Funcional_Specification, section 3.16,
-#
-# When the BMC detects the GPIO_FAULT signal indicating an SCP booting failure:
-# •  If a non-critical error/warning from the SCP occurs, the BMC blinks the Fault LED once.
-# •  If a critical error from the SCP occurs, the BMC turns on the Fault LED.
-# The BMC monitors the GPIO_FAULT signal from the SCP during SCP booting to determine whether
-# the error is non-critical or critical. A fatal error is indicated when the signal is On and then Off
-# continuously, followed by a “quiet” period of about three seconds, and this pattern repeats. If the “quiet”
-# period is longer than three seconds, the error is non-fatal. The BMC must set up appropriate debounce
-# times to detect such errors. The BMC is expected to turn on the Fault LED forever for fatal errors, or to
-# turn on the Fault LED and turn it off when the fault clears for non-fatal errors.
