*

* each other.
*
* The command field is updated by linux when it wants to
* reboot into recovery or to update radio or bootloader firmware.
* It is also updated by the bootloader when firmware update
* is complete (to boot into recovery for any final cleanup)
*
* The status field is written by the bootloader after the
* completion of an "update-radio" or "update-hboot" command.
*
* The recovery field is only written by linux and used
* for the system to send a message to recovery or the
* other way around.
