+ * The recovery tool communicates with the main system through /cache files.
+ * /cache/recovery/command - INPUT - command line for tool, one arg per line
+ * /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=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
+ * --set_encrypted_filesystem=on|off - enables / diasables encrypted fs
+ *
+ * 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 --
+ * 5. erase_volume() reformats /data
+ * 6. erase_volume() 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 --
+ * 8f. erase_volume() reformats /cache
+ * 8g. finish_recovery() erases BCB
+ * -- after this, rebooting will (try to) restart the main system --
+ * 9. main() calls reboot() to boot main system
