36 | Install a EFI_PEI_FIRMWARE_VOLUME_INFO PPI to inform PEI core about the existence of a new Firmware Volume.\r | |
37 | \r | |
38 | The function allocate the EFI_PEI_PPI_DESCRIPTOR structure and update the fields accordingly to parameter passed\r | |
39 | in and install the PPI.\r | |
40 | \r | |
41 | @param FvFormat Unique identifier of the format of the memory-mapped firmware volume. If NULL is specified,\r | |
42 | EFI_FIRMWARE_FILE_SYSTEM2_GUID is used as the Format GUID.\r | |
43 | @param FvInfo Points to a buffer which allows the EFI_PEI_FIRMWARE_VOLUME_PPI to\r | |
44 | process the volume. The format of this buffer is specific to the FvFormat. For\r | |
45 | memory-mapped firmware volumes, this typically points to the first byte of the\r | |
46 | firmware volume.\r | |
47 | @param FvInfoSize Size of the data provided by FvInfo. For memory-mapped firmware volumes, this is\r | |
48 | typically the size of the firmware volume.\r | |
49 | @param ParentFvName, ParentFileName If the firmware volume originally came from a firmware file, then these point to the\r | |
50 | parent firmware volume name and firmware volume file. If it did not originally come\r | |
51 | from a firmware file, these should be NULL\r | |
