This library hides where the 'XIP' Global Variable are located in the memory. It is expected the Sec/PrePi modules define the Global Variable area through the GlobalVariable HOB. The ArmPlatformGlobalVariableLib library allows access to global variables by their offsets in this region. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@12420 6f19259b-4bc3-4df7-8a09-765794883524
