2 | PCD Library Class provides PCD usage macro interface for all PCD types. It should be \r |
| 3 | included at any module who use PCD. \r |
| fb3df220 |
4 | \r |
| fb287b56 |
5 | If module use dynamic/dynamicex PCD, module should be linked to PEIM/DXE library \r |
| 6 | instance to access that PCD.\r |
| 7 | If module uses PatchableInModule type PCD, also need library instance produce LibPatchPcdSetPtr()\r |
| 8 | interface.\r |
| 9 | For FeatureFlag/Fixed PCD, macro interface is translated to an variable or macro\r |
| 10 | which is auto-generated by build tool in module's autogen.h/autogen.c\r |
