+ PCD Library Class provides a PCD usage macro interface for all PCD types.\r
+ It should be included in any module that uses PCD. If a module uses dynamic/dynamicex\r
+ PCD, module should be linked to a PEIM/DXE library instance to access that PCD.\r
+ If a module uses PatchableInModule type PCD, it also needs the library instance to produce\r
+ LibPatchPcdSetPtr() interface. For FeatureFlag/Fixed PCD, the macro interface is\r
+ translated to a variable or macro that is auto-generated by build tool in\r
module's autogen.h/autogen.c.\r
The PcdGetXX(), PcdSetXX(), PcdToken(), and PcdGetNextTokenSpace() operations are \r
only available prior to ExitBootServices(). If access to PCD values are required \r
There are no restrictions on the use of FeaturePcd(), FixedPcdGetXX(),\r
PatchPcdGetXX(), and PatchPcdSetXX().\r
