- *   /cache/recovery/log - OUTPUT - combined log file from recovery run(s)
- *   /cache/recovery/intent - OUTPUT - intent that was passed in
- *
- * The arguments which may be supplied in the recovery.command file:
- *   --send_intent=anystring - write the text out to recovery.intent
- *   --update_package=root:path - verify install an OTA package file
- *   --wipe_data - erase user data (and cache), then reboot
- *   --wipe_cache - wipe cache (but not user data), then reboot
- *
- * After completing, we remove /cache/recovery/command and reboot.
- * Arguments may also be supplied in the bootloader control block (BCB).
- * These important scenarios must be safely restartable at any point:
- *
- * FACTORY RESET
- * 1. user selects "factory reset"
- * 2. main system writes "--wipe_data" to /cache/recovery/command
- * 3. main system reboots into recovery
- * 4. get_args() writes BCB with "boot-recovery" and "--wipe_data"
- *    -- after this, rebooting will restart the erase --

- * 6. erase_root() reformats /cache
- * 7. finish_recovery() erases BCB
- *    -- after this, rebooting will restart the main system --
- * 8. main() calls reboot() to boot main system
- *
- * OTA INSTALL
- * 1. main system downloads OTA package to /cache/some-filename.zip
- * 2. main system writes "--update_package=CACHE:some-filename.zip"
- * 3. main system reboots into recovery
- * 4. get_args() writes BCB with "boot-recovery" and "--update_package=..."
- *    -- after this, rebooting will attempt to reinstall the update --
- * 5. install_package() attempts to install the update
- *    NOTE: the package install must itself be restartable from any point
- * 6. finish_recovery() erases BCB
- *    -- after this, rebooting will (try to) restart the main system --
- * 7. ** if install failed **
- *    7a. prompt_and_wait() shows an error icon and waits for the user
- *    7b; the user reboots (pulling the battery, etc) into the main system
- * 8. main() calls maybe_install_firmware_update()
- *    ** if the update contained radio/hboot firmware **:
- *    8a. m_i_f_u() writes BCB with "boot-recovery" and "--wipe_cache"
- *        -- after this, rebooting will reformat cache & restart main system --
- *    8b. m_i_f_u() writes firmware image into raw cache partition
- *    8c. m_i_f_u() writes BCB with "update-radio/hboot" and "--wipe_cache"
- *        -- after this, rebooting will attempt to reinstall firmware --
- *    8d. bootloader tries to flash firmware
- *    8e. bootloader writes BCB with "boot-recovery" (keeping "--wipe_cache")
- *        -- after this, rebooting will reformat cache & restart main system --
