We simulate the PSCI CPU_OFF operation by reseting the core via RMR. For secondaries, that already puts them in the holding pen waiting for a "warm boot" request as part of PSCI CPU_ON. For the BSP, we have to add logic to distinguish a regular boot from a CPU_OFF state, where, like the secondaries, the BSP needs to wait foor a "warm boot" request as part of CPU_ON.
Testing done:
- ACS suite now passes more tests (since it repeatedly calls code on secondaries via CPU_ON).
- Linux testing including offlining/onlineing CPU0, e.g. "echo 0 > /sys/devices/system/cpu/cpu0/online".
