   2  * File to implement LibScanHandleDatabase(), which is used by rEFInd's
   3  * driver-loading code (inherited from rEFIt), but which has not been
   4  * implemented in GNU-EFI and seems to have been dropped from current
   5  * versions of the Tianocore library. This function was taken from a git
   6  * site with EFI code. The original file bore the following copyright
