Native Platform Configuration Database (PCD) INFO PROTOCOL.
|
|
|
|
The protocol that provides additional information about items that reside in the PCD database.
|
|
|
|
Different with the EFI_GET_PCD_INFO_PROTOCOL defined in PI 1.2.1 specification,
|
|
the native PCD INFO PROTOCOL provide interfaces for dynamic and dynamic-ex type PCD.
|
|
The interfaces for dynamic type PCD do not require the token space guid as parameter,
|
|
but interfaces for dynamic-ex type PCD require token space guid as parameter.
