The general idea is that each core will release all of its threads into the secondary thread startup code, which will eventually wait in the secondary core holding area, for the appropriate bit in the PACA to be set. The kick_cpu function pointer will set that bit in the PACA, and thus "release" the core/thread to boot. We also need to do a few things that U-Boot normally does for CPUs (like enable branch prediction).
