0) Change the PEI core behavior to not install FV HOB for each FV INFO PPI installed. This allows more freedom to platform developer to choose to expose which FV to PEI core or DXE core.
1) Split MdePkg/Include/Library/PiLib.h to DxePiLib.h and PeiPiLib.h. These two library classes are for DXE phase and PEI phase. 2) Update the API names in DxePiLib and PeiPiLib to be longer ones to be more meaningfull and to avoid name collisions. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@4067 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.
