145def4c47SEmmanuel Vadot  MStar/SigmaStar's Armv7 SoCs that have more than one processor
155def4c47SEmmanuel Vadot  have a region of registers that allow setting the boot address
165def4c47SEmmanuel Vadot  and a magic number that allows secondary processors to leave
175def4c47SEmmanuel Vadot  the loop they are parked in by the boot ROM.
