Broadcom BCM2709, ARMv8, and missing CPU features

[Jeffrey Walton <noloader@gmail.com>]

Hi Everyone,

I recently purchased a Raspberry Pi 3. Its got a Broadcom SoC, and its
ARMv8. Its running a Debian-lite kernel, which I believe is a modified
4.4 kernel.

Below is the output from cpuinfo. I see ARMv8's crc32 is available,
but I don't see pmull, aes or sha. At the moment, I'm not sure if its
truly missing, or the execution environment is not quite correct.

My question is, what's going on with the device? Is the hardware truly
lacking the features, or is the image lagging behind capabilities?
