The reset value of IPIDR should be zero for Freescale chipset, per the following 2 manuals I checked: - P2020RM (https://www.nxp.com/webapp/Download?colCode=P2020RM) - P4080RM (https://www.nxp.com/webapp/Download?colCode=P4080RM) Currently it is set to 1, which leaves the IPI enabled on core 0 after power-on reset. Such may cause unexpected interrupt to be delivered to core 0 if the IPI is triggered from core 0 to other cores later.
