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.

Ok, makes sense. I did stumble over one machine basedon STiH412
the other day [1], but there probably isn't much shared with that
one. Since this a NAS server rather than an STB box, it's probably
less locked-down and potentially a target for OpenWRT or similar.

I just double checked with ST and STiH412 is a STiH407 family based SoC
so support still exists for this upstream. No idea what if any security is
enabled on this product though.

Most probably the A/V stack on it will be SDK2, although native upstream
multimedia drivers for this chipset are looking pretty good now.

Peter.
