ArmPlatformSecExtraAction() The PcdStandalone is a PCD ARM Ltd uses to make the difference between a standalone UEFI (boot from cold boot to Boot Manager without user intervention) and a Debug UEFI firmware (the firmware engineer has to copy the Normale World image into the DRAM to enable his/her firmware). By coping the firmware into DRAM in the non standalone version it is much faster than reflashing the NOR Flash after each build. ArmPlatformSecExtraAction() function is called just before the Sec module jump to normal world. The platform firmware can run extra actions at this stage.
