Broadcom tailor silicon to their customers.  For example, put it in a
different package or with different options enabled.

So the BCM2708 is the base silicon family, and the particular instance of
that in the Pi 0 and Pi 1 is the BCM2835.  The chip in the first Pis was a
side effect of other projects, which is why the BCM2708 is used in other
things.

The Pi 2 v1.0 used a BCM2836 (variation of 2708 with four Cortex A7 cores)
and the v1.2 and Pi 3 used a BCM2837 (variation of 2708 with four A53
cores).

The SoC in the Pi 4 is custom for that, so it's only the BCM2711.
