| 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. |
