+/// High-level procedure flow:
+///
+/// \verbatim
+///
+/// do {
+/// - Clear the Deep Exit Masks to allow Special Wake-up to occur
+/// - Put all EX chiplets in special wakeup
+/// - Mask the PM FIRs
+/// - Disable PMC OCC HEARTBEAT before halting and reset OCC
+/// - Halt and then Reset the PPC405
+/// - PMC moves to Vsafe value due to heartbeat loss
+/// - Force Vsafe value into voltage controller to cover the case that
+/// the Pstate hardware didn't move correctly
+/// - Reset PCBS-PM
+/// - Reset PMC
+/// As the PMC reset kills ALL of the configuration, the idle
+/// portion must be reestablished to allow that portion to operate.
+/// - Run SLW Initialiation
+/// - This allows special wake-up removal before exit
+/// - Reset PSS
+/// - Reset GPEs
+/// - Reset PBA
+/// - Reset SRAM Controller
+/// - Reset OCB
+/// - Clear special wakeups
+/// } while(0);
+///
+/// if error, clear special wakeups to leave this procedure clean
+///
+/// SLW engine reset is not done here as this will blow away all setup
+/// in istep 15. Thus, ALL manipulation of this is via calls to
+/// p8_poreslw_ioit or by p8_poreslw_recovery.
