This patch series adds support for SMCCCv1.2 ARCH_SOC_ID.
This doesn't add other changes added in SMCCC v1.2 yet. They will
follow these soon along with its first user SPCI/PSA-FF.

This is tested using upstream TF-A + the patch[3] fixing the original
implementation there.

Applied to arm64 (for-next/smccc), thanks!

Arnd -- Sudeep's reply to you about the sysfs groups seemed reasonable to me,
but please shout if you'd rather I dropped this in order to pursue an
alternative approach.

I missed the reply earlier, thanks for pointing me to it again.

I'm not entirely convinced, but don't revert it for now because of that,
I assume we can find a solution.

However, please have a look at the build failure report for patch 5
and fix it if you can see what went wrong.

        Arnd
