* `MTD\VENDOR_foo&PRODUCT_bar&NAME_baz`
If the `FirmwareGType` quirk is set for the device then the firmware is read back from the device at
daemon startup and parsed for the version number.
In the event the firmware has multiple child images then the device GUIDs are used as firmware IDs.
## Update Behavior
The MTD device is erased in chunks, written and then read back to verify.
