+ Describes a vendor-specific reset type. The string after "reboot-mode-"
+ maps a reboot mode to the parameters in the PSCI SYSTEM_RESET2 call.
+
+ Parameters are named reboot-mode-xxx = <type[, cookie]>, where xxx
+ is the name of the magic reboot mode, type is the lower 31 bits
+ of the reset_type, and, optionally, the cookie value. If the cookie
+ is not provided, it is defaulted to zero.
