This patch adds Cortex-A53 CPU cores to r8a7795 SoC for a total of 8
cores (4 x Cortex-A57 + 4 x Cortex-A53).

Thanks, I can confirm this works.
However, as the scheduler is not big.LITTLE aware (running processes are not
migrated automatically to the faster CA57 cores when these are idle), it makes
performance less deterministic.
What's the plan, then?
Waiting for big.LITTLE getting merged before enabling the A53? Or not
using the A53 at all?
Best regards
Dirk
