-/* Bootloader / Recovery Flow
- *
- * On every boot, the bootloader will read the bootloader_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 bootloader_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 if command == "update-hboot" -> update hboot image (below)
- * else -> boot boot.img (normal boot)
- *
- * Radio/Hboot 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 bootloader_message, leaving the recovery field
- *    unchanged, updating status, and setting command to
- *    "boot-recovery"
- * 9. reboot
- *
- * The bootloader will not modify or erase the cache partition.
- * It is recovery's responsibility to clean up the mess afterwards.
