Hi Evan,

I've some question about end user's provisioning.

As we knew, ufs are mainly adopted to boot device like mobile phone.
Usally after  provisioning operation, every data in ufs (eg. Android :
system, userdata, boot info and etc) would be removed. How end user
download and flash all data to ufs?. dd or another download tools?.
