*
* On every boot, the bootloader will read the recovery_message
* from flash and check the command field. The bootloader should
* deal with the command field not having a 0 terminator correctly
* (so as to not crash if the block is invalid or corrupt).
*
* The bootloader will have to publish the partition that contains
* the recovery_message to the linux kernel so it can update it.
*
* if command == "boot-recovery" -> boot recovery.img
* else if command == "update-radio" -> update radio image (below)
* else -> boot boot.img (normal boot)
*
* Radio Update Flow
* 1. the bootloader will attempt to load and validate the header
* 2. if the header is invalid, status="invalid-update", goto #8
* 3. display the busy image on-screen
* 4. if the update image is invalid, status="invalid-radio-image", goto #8
* 5. attempt to update the firmware (depending on the command)
* 6. if successful, status="okay", goto #8
* 7. if failed, and the old image can still boot, status="failed-update"
* 8. write the recovery_message, leaving the recovery field
