Hi KAMEZAWA-San, I found patch 1 of your series can be shared by code updating devices persistently, with a slight change. (See my patch 1, I think it can be squashed into your patch 1 if you feel good with it) This series adds support for persistently updating devices, however, it is based on KAMEZAWA-San's series. I post it here for an early review and will update it later.
