The denomination 'Normal' was used to make reference to the 'Normal' or 'Non Secure' or 'Non Trusted' world. To avoid confusion, this prefix has been removed from PCDs to define the normal world. The PCDs explicitely related to the Secure/Trusted World continue to have the 'Sec' prefix. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@12416 6f19259b-4bc3-4df7-8a09-765794883524
