The idea is to keep ArmPkg responsible for the ARM architectural modules and ArmPlatformPkg the ARM development platform packages (with their respective drivers). ArmPlatformPkg: Reduce driver dependency on ArmPlatform.h - Move some driver definitions from C-Macro to PCD values - Unify PCD driver namespace git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@11956 6f19259b-4bc3-4df7-8a09-765794883524
