STiH415 I'm sure never shipped. I'm reasonably sure STiH416 didn't
either. These SoCs were considered legacy even when I was at ST
~3 years ago.

Also remember these are STB SoC's, so JTAG fuses are blown in
production boxes, and also full security is enabled. This means the
primary bootloader will only boot a signed kernel. So if a end user
did happen to have a box they would be unable to upgrade their kernel.

>From the landing team perspective they were interesting in that they
shared many IPs with the STiH407 family on which future chipsets were
based, and were available to us when that silicon was harder to get
hold of. So we used it as a vehicle for upstreaming so that upstream
support was already quite good when STiH407 silicon did land on our
desk.

regards,

Peter.
