+ Firmware Volume specified by FvHandle. On this FvHandle, an EFI_FIRMWARE_VOLUME2_PROTOCOL protocol instance
+ should be located succesfully in order to carry out the Firmware Volume operations.
+
+ 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 FvHandle 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.
