25 *
26 * This structure describes the content of a block in flash
27 * that is used for recovery and the bootloader to talk to
28 * each other.
29 *
30 * The command field is updated by linux when it wants to
31 * reboot into recovery or to update radio or bootloader firmware.
32 * It is also updated by the bootloader when firmware update
33 * is complete (to boot into recovery for any final cleanup)
34 *
35 * The status field is written by the bootloader after the
36 * completion of an "update-radio" or "update-hboot" command.
37 *
38 * The recovery field is only written by linux and used
39 * for the system to send a message to recovery or the
40 * other way around.
