A caution about talking about "rpi3" vs.
"rpi2" for what is supported. . .

Raspberry Pi 2 Model B V1.2 is Cortex-A53 based
(so arm64/aarch64). (A BCM2837, not a BCM2836.)
This dates about to something like 2014 based
on the pictures showing the (c) notice on the
boards but I think it was released somewhat
later. So rpi2 V1.2 is like the rpi3 for most
things.

V1.1 and before for rpi2 were armv7 (BCM2836)
based.

So rpi2 V1.2 and rpi3 go together.

And rpi2 V1.1 and before are separate.

(A single, modern distribution of the official
Raspbian software for the rpi2 does support
all the V1.x boards if I understand right:
they handle the V1.2 Cortex-A53 in AArch32
state mode to make user processes look like
a 32-bit armv7 context.)
