PCD Purpose
gEfiMdeModulePkgTokenSpaceGuid. PcdFlashNvStorageVariableBase Base address of the NV variable range in flash device.
gEfiMdeModulePkgTokenSpaceGuid. PcdFlashNvStorageVariableSize Size of the non-volatile variable range. Note that this value should less than or equal to PcdFlashNvStorageFtwSpareSize.
gEfiMdeModulePkgTokenSpaceGuid. PcdFlashNvStorageFtwWorkingBase Base address of the FTW working block range in flash device.
gEfiMdeModulePkgTokenSpaceGuid. PcdFlashNvStorageFtwWorkingSize Size of the FTW working block range.
gEfiMdeModulePkgTokenSpaceGuid. PcdFlashNvStorageFtwSpareBase Base address of the FTW spare block range in flash device. Note that this value should be block size aligned.
gEfiMdeModulePkgTokenSpaceGuid. PcdFlashNvStorageFtwSpareSize Size of the FTW spare block range. Note that this value should larger than PcdFlashNvStorageVariableSize and block size aligned.
gMinPlatformPkgTokenSpaceGuid. PcdFlashFvSecurityBase Security FV base address.
gMinPlatformPkgTokenSpaceGuid. PcdFlashFvSecuritySize Security FV size.
