- Routine Description:
- Get the imageid of last image block: EFI_HII_IIBT_END_BLOCK when input
- ImageId is zero, otherwise return the address of the
- corresponding image block with identifier specified by ImageId.
-
- Arguments:
- ImageBlock - Points to the beginning of a series of image blocks stored in order.
- ImageId - If input ImageId is 0, output the image id of the EFI_HII_IIBT_END_BLOCK;
- else use this id to find its corresponding image block address.
-
- Returns:
- The image block address when input ImageId is not zero; otherwise return NULL.
