Merge the PI enabling works from the branch
First round of PI enabling work: 1) PiPeiCis changes (CONST, EFI_PEI_FILE_HANDLE.. etc) 2) Make use of FirmwareVolume 2 protocol. 3) Verified for Nt32Pkg and real platform for S3. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@3772 6f19259b-4bc3-4df7-8a09-765794883524

/**
|
||||
Allocate and fill a buffer with an image identified by a Firmware File GUID name and a Firmware Section type.
|
||||
The Firmware Volumes to search for the Firmware File can be specified to be either all Firmware Volumes
|
||||
in the system, or the Firmware Volume which contains the Firmware File specified by an image handle.
|
||||
|
||||
If ImageHandle is NULL, all Firmware Volumes in the system will be searched. If ImageHandle is not NULL,
|
||||
ImageHandle is interpreted as EFI_PEI_FILE_HANDLE for the implementation of this function for PEI phase.
|
||||
The input parameter ImageHandle is interpreted as EFI_HANDLE, on which an EFI_LOADED_IMAGE_PROTOCOL
|
||||
is installed, for the implementation of this function for DXE phase. The search always starts from the FV
|
||||
identified by ImageHandle. If WithinImageFv is TRUE, search will only be performed on the first FV. If WithinImageFv
|
||||
is FALSE, search will continue on other FVs if it fails on the first FV. The search order of Firmware Volumes is
|
||||
deterministic but arbitrary if no new firmware volume is added into the system between each search.
|
||||
|
||||
The search order for the section type specified by SectionType in the Firmware File is using a depth-first
|
||||
and left-to-right algorithm through all sections. The first section found to match SectionType will be returned.
|
||||
|
||||
If SectionType is EFI_SECTION_PE32, EFI_SECTION_PE32 will be used as Firmware Section type
|
||||
to read Firmware Section data from the Firmware File. If no such section exists, the function will try
|
||||
to read a Firmware File named with NameGuid. If no such file exists, EFI_NOT_FOUND is returned.
|
||||
|
||||
If SectionType is EFI_SECTION_TE, EFI_SECTION_TE will be used as Firmware Section type to read Firmware Section
|
||||
data from the Firmware File. If no such section exists, EFI_SECTION_PE32 will be used as Firmware Section type to
|
||||
read Firmware Section data from the Firmware File. If no such section exists, the function will try to read a Firmware
|
||||
File named with NameGuid. If no such file exists, EFI_NOT_FOUND is returned.
|
||||
|
||||
The data and size is returned by Buffer and Size. The caller is responsible to free the Buffer allocated
|
||||
by this function. This function can only be called at TPL_NOTIFY and below.
|
||||
|
||||
If ImageHandle is NULL and WithinImage is TRUE, then ASSERT ();
|
||||
If NameGuid is NULL, then ASSERT();
|
||||
If Buffer is NULL, then ASSERT();
|
||||
If Size is NULL, then ASSERT().
|
||||
|
||||
@param NameGuid The GUID name of a Firmware File.
|
||||
@param SectionType The Firmware Section type.
|
||||
@param Buffer On output, Buffer contains the the data read from the section in the Firmware File found.
|
||||
@param Size On output, the size of Buffer.
|
||||
|
||||
@retval EFI_SUCCESS The image is found and data and size is returned.
|
||||
@retval EFI_NOT_FOUND The image specified by NameGuid and SectionType can't be found.
|
||||
@retval EFI_OUT_OF_RESOURCES There were not enough resources to allocate the output data buffer or complete the operations.
|
||||
@retval EFI_DEVICE_ERROR A hardware error occurs during reading from the Firmware Volume.
|
||||
@retval EFI_ACCESS_DENIED The firmware volume containing the searched Firmware File is configured to disallow reads.
