30 Process a firmware volume and create a volume handle.\r
31\r
32 Create a volume handle from the information in the buffer. For\r
33 memory-mapped firmware volumes, Buffer and BufferSize refer to\r
34 the start of the firmware volume and the firmware volume size.\r
35 For non memory-mapped firmware volumes, this points to a\r
36 buffer which contains the necessary information for creating\r
37 the firmware volume handle. Normally, these values are derived\r
38 from the EFI_FIRMWARE_VOLUME_INFO_PPI.\r

45 @param FvHandle Points to the returned firmware volume\r
46 handle. The firmware volume handle must\r
