Searches all the available firmware volumes and returns the first matching FFS section.

This function searches all the firmware volumes for FFS files with an FFS filename
|
|
specified by NameGuid. The order in which the firmware volumes are searched is not
|
|
deterministic. For each FFS file found, a search is made for FFS sections of type
|
|
SectionType. If the FFS file contains at least SectionInstance instances of the FFS
|
|
section specified by SectionType, then the SectionInstance instance is returned in
|
|
Buffer. Buffer is allocated using AllocatePool(), and the size of the allocated buffer
|
|
is returned in Size.
|
|
|
|
If SectionType is EFI_SECTION_TE, and the search with an FFS file fails,
|
|
the search will be retried with a section type of EFI_SECTION_PE32.
