Fix coverity finding in psci_cpu_on, in which target_idx is directly assigned the return value from plat_core_pos_by_mpidr. If the latter returns a negative or large positive value, it can trigger an out of bounds overflow for the psci_cpu_pd_nodes array. >>>> CID 382009: (OVERRUN) >>>> Overrunning callee's array of size 8 by passing argument "target_idx" (which evaluates to 4294967295) in call to "psci_spin_lock_cpu". > 80 psci_spin_lock_cpu(target_idx); >>>> CID 382009: (OVERRUN) >>>> Overrunning callee's array of size 8 by passing argument "target_idx" (which evaluates to 4294967295) in call to "psci_spin_unlock_cpu". > 160 psci_spin_unlock_cpu(target_idx); Signed-off-by: Olivier Deprez <olivier.deprez@arm.com> Change-Id: Ibc46934e9ca7fdcaeebd010e5c6954dcf2dcf8c7
