Big Little Disable

[nifares]

hello, i'm not a fan of low core, how can i disable the little core, they should not be visible also should not be addressed

from the linux shell you can disable three A53 cores with
cpu 1-3 with

# echo 0 > /sys/devices/system/cpu/cpu1/online
# echo 0 > /sys/devices/system/cpu/cpu2/online
# echo 0 > /sys/devices/system/cpu/cpu3/online

put the commands into rc.local to get this reboot permanent.

One A53 core (cpu0) has to stay and you will loose the interrupt-binding
to this cores.

What gain do you expect from this move?
