> The boot_lock is something that was required for ARM development
> platforms to ensure that the delay calibration worked properly.  This
> is not necessary for modern platforms that have better bus bandwidth
> and do not need to calibrate the delay loop for secondary cores.
> Remove the boot_lock entirely.
