This patch series completes the description of the Cortex-A55 lusters by describing L3 caches, CPU cores 1-7, CPU map, PSCI for CPU bring up, CPUIdle, and CPU core clocks. This has been tested on the Spider development board, where now all 8 Cortex-A55 CPU cores are available after boot. All but the first CPU core can be controlled from sysfs (/sys/*/*/cpu/cpu[0-7]/online). CPU core performance follows the CPU core clocks, when changing the frequency of the latter. I plan to queue this in renesas-devel for v5.20. Thanks for your comments!
