+ Description: These files show the system reset cause, as following:
+ COMEX thermal shutdown; wathchdog power off or reset was derived
+ by one of the next components: COMEX, switch board or by Small Form
+ Factor mezzanine, reset requested from ASIC, reset cuased by BIOS
+ reload. Value 1 in file means this is reset cause, 0 - otherwise.
+ Only one of the above causes could be 1 at the same time, representing
+ only last reset cause.
