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. The 'ARM Standalone' concept has moved to the implementation of ArmPlatformSecExtraAction() for the ARM development boards (in ArmPlatformPkg/Library/DebugSecExtraActionLib). ArmPlatformPkg: Enable DebugAgentLib in Sec and PrePeiCore ArmPlatformPkg: Fix line endings in some source files Use CR+LF line endings as defined by the EDK2 coding convention git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@11991 6f19259b-4bc3-4df7-8a09-765794883524
