This driver parses the reboot commands like "reboot bootloader" and "reboot recovery" to get a boot mode described in the device tree , then call the write interfae to store the boot mode in some place like special register or sram, which can be read by the bootloader after system reboot, then the bootloader can take different action according to the mode stored. This is commonly used on Android based devices, in order to reboot the device into fastboot or recovery mode.
