No objections to the patch, but would it be possible to just add all the missing
ones here to the degree that they are known already? I don't see any entries for
Cortex-A34, Cortex-A65AE, Cortex-A78, Cortex-A78C, Cortex-A78AE,
Neoverse-E1, Neoverse-V1, Cortex-X1, Cortex-X2, Cortex-A510, Cortex-A710
and Cortex-R82 among the Arm-designed cores that can run Linux, and there
are probably others that I missed going through the list.
