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