Chiming in on an old thread, please check with those in the know whether
these cores are Spectre-v3a/4-safe, and if so, add the MIDR to the
corresponding white/blacklists in arch/arm64/kernel/proton-pack.c

Also, please check for any erratas and supported-but-not-advertized-for-
-reasons features that may need to be implemented.
Doing this early will ensure we will all spend less % of our time
pulling out what remains of our hair when the platform suddenly
crashes for no reason!
