As can be seen, the secondary CPUs check _hotplug_addr for a non zero

Linux mainline too has this hardcoded +0x1c.

You half read the Linux code... This offset is only add when there is a secure firmware (detected by "samsung,secure-firmware" node in the device tree).

On the Arndale the node doesn't exist.
