|
|
*
|
|
* 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.
