Before this patch, clust1 has little core0~3, clust0 has big core0~3
cpu_l | cpu0 |
cpu_l | cpu1 | clust1
cpu_l | cpu2 |
cpu_l | cpu3 |
----------------------
cpu_b | cpu4 |
cpu_b | cpu5 | clust0
cpu_b | cpu6 |
cpu_b | cpu7 |
With this patch, clust0 will have little core0~3, clust1 will have big core0~3
cpu_l | cpu0 |
cpu_l | cpu1 | clust0
cpu_l | cpu2 |
cpu_l | cpu3 |
----------------------
cpu_b | cpu4 |
cpu_b | cpu5 | clust1
cpu_b | cpu6 |
cpu_b | cpu7 |
It makes no other change, just keep same with other SoCs definations.
