2 | Native Platform Configuration Database (PCD) INFO PROTOCOL.\r | |
3 | \r | |
4 | The protocol that provides additional information about items that reside in the PCD database.\r | |
5 | \r | |
6 | Different with the EFI_GET_PCD_INFO_PROTOCOL defined in PI 1.2.1 specification,\r | |
9095d37b | 7 | the native PCD INFO PROTOCOL provide interfaces for dynamic and dynamic-ex type PCD.\r |
96d6d004 SZ |
8 | The interfaces for dynamic type PCD do not require the token space guid as parameter,\r |
9 | but interfaces for dynamic-ex type PCD require token space guid as parameter.\r | |
