+ If the Fv has already been processed, skip it. If the Fv has not been\r
+ processed then mark it as being processed, as we are about to process it.\r
+ Read the Fv and add any driver in the Fv to the mDiscoveredList.The\r
+ mDiscoveredList is never free'ed and contains variables that define\r
+ the other states the DXE driver transitions to..\r
+ While you are at it read the A Priori file into memory.\r
