+Generic reboot mode communication driver

+This driver get reboot mode arguments from userspace
+and stores it in special register or ram . Then the
+bootloader will read it and take different action
+according the argument stored.
+
+Required properties:
+ - compatible = "reboot-mode" or other vendor compatible string;
+
+Each mode is represented as a sub-node of reboot_mode:
+
+Subnode properties:
+ - linux,mode: reboot mode command,such as "loader","recover", "fastboot".
